Description

  The present invention relates to a work support system, a setting device, a setting method, and a setting program.

In business such as building management, workers may be allowed to carry out work in target facilities such as company premises or inside buildings. For example, such work includes equipment inspection, patrol and cleaning work. In such operations, a work record is created regarding whether or not the requested work has been performed at the target facility, or how much the work has been performed.
For example, in the case of the cleaning work, the worker visits the cleaning area in the target facility regularly or irregularly in a predetermined order and cleans each cleaning area. At this time, an operation record is created as to whether or not the points to be cleaned have been cleaned without omission. The work record may be based on the self-report of the worker, but it is desirable that the work record be more reliable.

  A more reliable work record is desired not only for cleaning work, but also for maintenance inspection work for equipment and the like and patrol work. For example, in the field of maintenance inspection work, a portable terminal device that supports inspection and maintenance of facilities has been proposed (for example, Patent Document 1). The portable terminal device includes an interface device that receives a facility ID output from a wireless tag attached to the facility. By making the portable terminal device carried by the worker receive the equipment ID, it is possible to record that the worker was near the equipment.

Japanese Patent Laid-Open No. 10-222543

However, the presence or absence of reception of a signal from a wireless tag attached to the facility may not be sufficient as a work record. For example, there is a possibility that the signal of the wireless tag may be erroneously detected outside the work area. Further, for example, even if a worker is in the work area, there is a risk that an unauthorized record is intentionally created without performing the work sufficiently.
An object of the present invention is to improve the reliability of work records relating to work performed by workers in a work area.

  According to an aspect of the present invention, a work support system including a terminal device carried by a worker working in a work area and a setting device communicating with the terminal device is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
(Overall configuration of work support system)
FIG. 1 is a schematic configuration diagram illustrating an entire work support system according to the first embodiment. Here, a case where work history information in a plurality of work areas 1a, 1b, and 1c in a work target facility is generated as work records will be described. The work in the work areas 1a to 1c may be, for example, equipment inspection, guard patrol, or cleaning work, but is not limited thereto. Further, the work area may be a plurality of places or one place. The work areas 1a to 1c may be a plurality of areas in a single facility or may be distributed in different facilities.
The work support system includes a management terminal device 3 used by the work manager 2, a work terminal device 5 carried by the worker 4, wireless transmitters 6a and 6b installed in the work areas 1a to 1c, and 6c. In the following description, the work areas 1a to 1c may be collectively referred to as “work area 1”. The wireless transmitters 6a to 6c may be collectively referred to as “wireless transmitter 6”.

  The management terminal device 3 registers an identification signal unique to each wireless transmitter 6 installed in the work area 1. The wireless transmitter 6 repeatedly transmits a unique identification signal at a constant transmission cycle T0 by short-range wireless communication. The wireless transmitter 6 may be, for example, an active RFID (Radio Frequency IDentification) tag that has a power source and periodically transmits a beacon signal. Such active RFID tags include, for example, iBeacon (trademark) compliant with Bluetooth (registered trademark) LE, but are not limited thereto.

The management terminal device 3 sets a set time and a set intensity for each work area 1. The set time is a threshold used for determining whether or not work is performed based on the stay time of the worker 4 in each work area 1. The set time is compared with the accumulated time of the reception time when the work terminal device 5 receives the identification signal of the wireless transmitter 6 in each work area 1. When the accumulated time is equal to or longer than the set time, it is determined that the work in the work area 1 is performed. When the accumulated time is less than the set time, the work in the work area 1 is determined to be incomplete, insufficient, or not performed. Is done.
The set strength is a threshold value used for determining whether or not the reception time of the identification signal is accumulated based on the reception strength of the identification signal of the wireless transmitter 6. The set strength is compared with the reception strength of the identification signal. The reception time is accumulated when the reception strength is equal to or higher than the set strength, and the reception time is not accumulated when the reception strength is less than the set strength.

  The management terminal device 3 generates identification information of the wireless transmitters 6a to 6c installed in the work areas 1a to 1c, and area information representing the set times and set strengths of the work areas 1a to 1c, respectively. FIG. 2 is a diagram illustrating a first example of area information. The area information includes information elements “work area”, “identification signal”, “setting strength”, and “setting time”. The information element “work area” designates work area 1. The information element “identification signal” indicates the identification signal of the wireless transmitter 6 installed in the designated work area 1. The information element “set strength” indicates the set strength set for the designated work area 1. The information element “set time” indicates the set time set for the designated work area 1.

For example, in the area information example of FIG. 2, the identification signal of the wireless transmitter 6 installed in the work area 1a is “id001”, and the set intensity and set time set for the work area 1a are “−70 dBm”, respectively. "And" 10 minutes ".
In this way, the work areas 1a to 1c are associated with the identification signals of the wireless transmitters 6a to 6c, respectively, according to the area information. That is, the work areas 1a to 1c are associated with the wireless transmitters 6a to 6c, respectively, according to the area information. Similarly, the setting strengths and setting times of the work areas 1a to 1c are associated with the work areas 1a to 1c, respectively, according to the area information. Thereby, the setting intensity and the setting time of the work areas 1a to 1c are associated with the wireless transmitters 6a to 6c, respectively, by the area information.

  Please refer to FIG. The work terminal device 5 receives the area information from the management terminal device 3. For example, the management terminal device 3 and the work terminal device 5 may be communicable via the communication network 10. The communication network 10 may be a wireless communication network according to a communication scheme such as W-CDMA (Wideband Code Division Multiple Access), CDMA2000, LTE (Long Term Evolution), and the like. The work terminal device 5 may receive area information from the management terminal device 3 via the communication network 10. Further, for example, the work terminal device 5 and the management terminal device 3 may be connected by a wired line, and the work terminal device 5 may receive area information from the management terminal device 3 via the wired line. .

The worker 4 carries the work terminal device 5 and visits the work areas 1a to 1c in a predetermined order, and performs work in each of the work areas 1a to 1c. For example, it is assumed that the worker 4 visits the work area 1a, the work area 1b, and the work area 1c in this order.
First, the work terminal device 5 receives the identification signal “id001” of the wireless transmitter 6a in the work area 1a. At this time, the reception time of the identification signal of the wireless transmitter 6a is accumulated. For example, when the reception strength of the identification signal of the wireless transmitter 6a is equal to or higher than the set strength “−70 dBm” of the work area 1a set by the area information, the work terminal device 5 may accumulate the reception time. In the following description, the reception time of the accumulated identification signal may be referred to as “accumulated reception time”.
Then, when the accumulated reception time is equal to or longer than the set time “10 minutes” of the work area 1a set by the area information, it is determined that the work in the work area 1a has been performed.

When the work in the work area 1a is completed, the worker 4 visits the work area 1b. When the work in the work area 1b is completed, the worker 4 visits the work area 1c. As in the case of the work area 1a, it is determined that work in the work areas 1b and 1c has been performed when the accumulated reception times of the identification signals of the wireless transmitters 6b and 6c are longer than the set times of the work areas 1b and 1c, respectively. Is done.
The work terminal device 5 is an example of a terminal device described in the claims. The management terminal device 3 is an example of a setting device and a wireless receiver.

(Working sequence in the first embodiment)
Next, a work sequence in the work support system of the first embodiment will be described with reference to FIG. In the work support system of the first embodiment, the accumulation of the reception time of the identification signal of the wireless transmitter 6 and the work execution determination are executed by the work terminal device 5.
In the following description, the setting strength associated with the wireless transmitter 6 based on the area information may be referred to as “setting strength corresponding to the wireless transmitter 6”. The set time associated with the wireless transmitter 6 by the area information may be referred to as “set time corresponding to the wireless transmitter 6”.

In addition, the setting strength associated with the wireless transmitter 6a by the area information may be referred to as “setting strength corresponding to the wireless transmitter 6a”. The set time associated with the wireless transmitter 6a by the area information may be referred to as “set time corresponding to the wireless transmitter 6a”.
The work area 1 where the wireless transmitter 6 is installed uniquely corresponds to the identification signal of the wireless transmitter 6. For this reason, in the following description, the work area 1 in which the wireless transmitter 6 that is the transmission source of the identification signal is installed may be referred to as a “work area corresponding to the identification signal”.

  In step S100, the work manager 2 performs area information setting processing in the management terminal device 3 prior to work. The area information setting process will be described later with reference to FIGS. In step S <b> 101, the work manager 2 performs a work instruction input operation in the work areas 1 a to 1 c on the management terminal device 3. The management terminal device 3 that has received the input operation transmits to the work terminal device 5 the work instruction signal for instructing the worker 4 to work in the work areas 1a to 1c and the area information set in step S100. In step S102, the work terminal apparatus 5 receives the work instruction signal and the area information.

  The worker 4 arriving at the work target facility in step S103 performs a start notification operation on the work terminal device 5 to notify the work manager 2 of the work start. For example, the worker 4 may perform the start notification operation by reading the entrance tag provided at the entrance of the facility to be worked with the work terminal device 5, or the start notification operation by operating the work terminal device 5. May be performed. When accepting the start notification operation, the work terminal device 5 transmits a work start signal notifying the start of work to the management terminal device 3. When the work start signal is received, in step S104, the management terminal apparatus 3 stores the work start in the work areas 1a to 1c as the work status. The management terminal device 3 may notify the work manager 2 by displaying the stored work status.

When the worker 4 enters the first work area 1a and starts work, in step S105, the work terminal device 5 receives the identification signal “id001” from the wireless transmitter 6a in the work area 1a. When the reception strength of the identification signal of the wireless transmitter 6a is equal to or higher than the set strength “−70 dBm” corresponding to the wireless transmitter 6a, the work terminal device 5 accumulates the reception time. The reception time accumulating process may be realized, for example, by adding the transmission period T0 of the identification signal of the wireless transmitter 6 to the accumulated reception time every time an identification signal having a set strength or higher is received once.
The work terminal device 5 may accumulate the number of receptions of the identification signal instead of the reception time itself. Since the accumulated reception time is obtained by the product of the number of receptions and the transmission cycle T0, the number of receptions can be used as a value representing the reception time. Thus, in this specification, the accumulation of the reception time includes not only the reception time itself but also accumulation of other values representing the reception time.

  In step S106, the work terminal device 5 determines whether or not the accumulated reception time is equal to or longer than the set time “10 minutes” corresponding to the wireless transmitter 6a. When the accumulated reception time is less than the set time (No in step S106), the work terminal device 5 determines that the work in the work area 1a has not been completed, is insufficient, or is not performed. Thereafter, the process returns to step S105. When the accumulated reception time is equal to or longer than the set time (Yes in step S106), the work terminal device 5 determines that the work in the work area 1a has been performed. Thereafter, the process proceeds to step S107. In step S107, the work terminal device 5 stores the current time as work history information. In this way, work history information in the work area 1a is generated. Note that the reception process of the identification signal in the work terminal device 5 will be described in detail later with reference to FIGS.

When the work in the work area 1a is completed, the worker 4 enters the next work area 1b and starts work. In step S108, the work terminal device 5 receives the identification signal “id002” from the wireless transmitter 6b in the work area 1b. Thereafter, similar to the processing in steps S105 to S107 in the case of the work area 1a, accumulation of reception time, determination of work execution, and generation of work history information are performed. The same applies to the work area 1c next to the work area 1b.
When the work in the work area 1c is completed, in step S109, the work terminal device 5 notifies the work manager 2 of the work end in the work areas 1a to 1c, and the work history information stored in step S107. Is transmitted to the management terminal device 3. For example, the work terminal device 5 transmits a notification work end signal and work history information when the worker 4 reads the exit tag provided at the entrance of the work target facility with the work terminal device 5. Good. In addition, for example, the work terminal device 5 may automatically transmit a notification work end signal and work history information when the accumulated reception time is equal to or longer than the set time in the last work area 1c.

  When the work end signal is received, in step S110, the management terminal device 3 stores the work end in the work areas 1a to 1c as the work status. In addition, the management terminal device 3 stores the received work history information. In this way, work history information including the work end time of each of the work areas 1a to 1c can be recorded in the management terminal device 3 as a work record.

(Configuration of management terminal device)
Next, the configuration of the management terminal device 3 will be described. Please refer to FIG. As the management terminal device 3, a smartphone or a mobile phone can be adopted. However, the management terminal device 3 is not limited to these. The management terminal device 3 is portable, has a short-range wireless communication function for receiving the identification signal of the wireless transmitter 6, a communication function with the work terminal device 5, and an information processing function, and stores an application program. Other devices that can realize these functions may be used.

The management terminal device 3 includes a communication unit 20, a near field communication unit 21, an operation unit 22, a display unit 23, a storage unit 24, and a control unit 25.
The communication unit 20 includes wired and wireless communication interfaces, and is connected to the communication network 10 via a connector or an antenna.
The short-range communication unit 21 includes an interface circuit for performing short-range wireless communication in accordance with a communication method such as iBeacon (trademark) compliant with, for example, Bluetooth (registered trademark) LE. The short-range wireless communication range is about several meters to several tens of meters, whereby the short-range communication unit 21 receives the identification signal transmitted from the wireless transmitter 6.

The operation unit 22 functions as an information input unit, and may include an input button, a touch panel provided on the display screen of the display unit 23, and the like. The operation unit 22 is used to accept data input and operation input to the management terminal device 3. The display unit 23 functions as a display unit, and displays various types of information under the control of the control unit 25. The storage unit 24 includes a nonvolatile memory and / or a hard disk drive device. The storage unit 24 stores various data, application programs, and the like.
For example, the storage unit 24 may store area information generated by the management terminal device 3, work history information received from the work terminal device 5, and work situations in the work areas 1a to 1c.

In addition, the storage unit 24 has a setting program 26 that causes the control unit 25 to perform setting processing of area information, and a process for managing work in the work areas 1a to 1c by communicating with the work terminal device 5 in the control unit 25. A management program 27 to be executed may be stored.
The setting program 26 and the management program 27 may be recorded on a machine-readable recording medium, read by a medium reading device (not shown), and installed in the storage unit 24. Further, the setting program 26 and the management program 27 may be downloaded from the communication network 10 via the communication unit 20 and installed in the storage unit 24.

  The communication unit 20, the short-range communication unit 21, the operation unit 22, the display unit 23, and the storage unit 24 are connected to the control unit 25. The control unit 25 includes a processor, its peripheral circuits, a ROM (Read Only Memory), and a RAM (Random Access Memory). The control unit 25 reads the setting program 26 and the management program 27 from the storage unit 24 and executes these programs. Hereinafter, the functional configuration of the control unit 25 will be described.

  The control unit 25 includes a reception intensity setting unit 30, a set time presentation unit 31, an area information generation unit 32, an area information transmission unit 33, a start signal reception unit 34, an end signal reception unit 35, a work history reception unit 36, and a work history record. The unit 37 is provided. The setting program 26 includes a command for causing the control unit 25 to execute the processes of the reception intensity setting unit 30, the set time presentation unit 31, and the area information generation unit 32. The management program 27 includes instructions for causing the control unit 25 to execute the processes of the area information transmitting unit 33, the start signal receiving unit 34, the end signal receiving unit 35, the work history receiving unit 36, and the work history recording unit 37.

  The reception intensity setting unit 30 sets the setting intensity of the work area 1. First, the reception intensity setting unit 30 designates the identification signal of the wireless transmitter 6 installed in the work area 1 as a reception target. For example, when the work manager 2 designates the identification signal of the wireless transmitter 6a installed in the work area 1a as a reception target, the work manager 2 brings the management terminal device 3 close to the wireless transmitter 6a and receives the identification signal with high strength. By doing so, the identification signal of the wireless transmitter 6a may be designated. Similarly, in the work areas 1b and 1c, the identification signals of the wireless transmitters 6b and 6c may be designated, respectively.

Next, the reception strength setting unit 30 detects the reception strength when the identification signal of the wireless transmitter 6 is received in the work area 1. For example, when detecting the reception strength of the identification signal of the wireless transmitter 6a in the work area 1a, the reception strength setting unit 30 determines whether the reception signal received by the short-range communication unit 21 is the identification signal of the wireless transmitter 6a. Determine whether. The reception strength setting unit 30 detects the reception strength when the received signal is an identification signal of the wireless transmitter 6a, and does not detect the reception strength when the received signal is not the identification signal of the wireless transmitter 6a.
The reception strength setting unit 30 may use an average value of the reception strengths of the identification signals received a plurality of times during a predetermined measurement time as a detection value of the reception strength. During the measurement time, for example, the work manager 2 may place the management terminal device 3 in a place farthest from the wireless transmitter 6 in the work area 1 within a range where the worker 4 works. For example, the work manager 2 may cause the short-range communication unit 21 to receive the identification signal at a plurality of reception positions by carrying the management terminal device 3 and moving in the work area 1. Similarly, in the case of the work areas 1b and 1c, the reception intensity may be detected.
The operation unit 22 starts the reception of the identification signal by the short-range communication unit 21 or the detection start of the reception strength by the reception strength setting unit 30 so that the reception strength can be detected when the management terminal device 3 is at a desired position. May be accepted by the work manager 2.

The reception intensity setting unit 30 presents the detected reception intensity on the display unit 23. FIG. 5A and FIG. 5B are explanatory diagrams of an example of a setting screen 50 displayed on the display unit 23. The setting screen 50 includes a reception intensity index 51 at the current position, a setting intensity slider 52, a setting intensity index 53, a setting intensity display area 54, a setting time display area 55, a setting time slider 56, and a registration button 57. Have
When the reception strength is detected, the reception strength setting unit 30 sets the detection value of the reception strength to the initial value of the setting strength. Also, the reception intensity setting unit 30 moves the reception intensity index 51 from the initial position shown in FIG. 5A to the position shown in FIG. 5B according to the detection value, thereby detecting the reception intensity detected at the current position. Is presented so as to be visually recognized as the degree of separation from the wireless transmitter 6.

  The set strength in which the initial value is set from the detected value of the received strength can be changed and input by operating the set strength slider 52. Further, by operating the registration button 57, the work manager 2 can make a fixed input of the set intensity. The operation unit 22 receives the change input and the confirmation input as input operations for setting strength. The set intensity is represented by a set intensity index 53, and the value is displayed in the set intensity display area 54. When the positions of the set intensity index 53 and the received intensity index 51 match (that is, the initial value state), the set intensity matches the received intensity at the current position. When the set intensity is higher, the range in which the work terminal device 5 detects the identification signal, that is, the range in which the reception time is accumulated becomes narrower. On the contrary, when the setting intensity is lower, the range in which the work terminal device 5 detects the identification signal becomes wider. The reception intensity setting unit 30 outputs the identification signals specified for the work areas 1a to 1c and the setting intensity set for the work areas 1a to 1c to the area information generation unit 32, respectively.

Please refer to FIG. The set time presentation unit 31 calculates an initial value of the set time according to the reception strength detected by the reception strength setting unit 30, that is, the reception strength of the identification signal received by the short-range communication unit 21.
For example, it is assumed that the transmission intensity of the wireless transmitter 6 is set to be constant between the work areas 1a to 1c. In this case, the wider the work area 1 is, the longer the distance between the management terminal device 3 and the wireless transmitter 6 when the reception strength setting unit 30 detects the reception strength, the lower the reception strength. Therefore, the set time presentation unit 31 may calculate a longer initial value as the reception strength is lower, and may calculate a longer initial value when the work area 1 is wider. For example, the set time presentation unit 31 may calculate an initial value that is proportional to 1 / ^{4th of the} received intensity (1 / (received intensity) ⁴ ).

The set time presentation unit 31 presents the calculated initial value of the set time on the display unit 23. Reference is made to FIG. 5A and FIG. Before the set time slider 56 is operated, an initial value of the set time is presented in the set time display area 55. By operating the set time slider 56, the work manager 2 can input a change in the set time. Further, by operating the registration button 57, the work manager 2 can perform a fixed input of the set time. The operation unit 22 receives the change input and the confirmation input as input operations for the set time.
By performing a definite input after the change input, the input value of the change input is set as the set time. An initial value is set as a set time by performing a definite input without changing. The set time presentation unit 31 receives an input of the set time from the operation unit 22, and outputs the set time set for each work area 1 to the area information generation unit 32.

Please refer to FIG. The area information generation unit 32 generates area information based on the identification signal and the setting intensity received from the reception intensity setting unit 30 and the setting time received from the setting time presentation unit 31. Further, the area information generation unit 32 stores the area information in the storage unit 24.
When the operation instruction 22 is accepted by the operation unit 22, the area information transmission unit 33 transmits a work instruction signal and area information to the work terminal device 5.
The start signal receiving unit 34 receives the work start signal transmitted from the work terminal device 5. When receiving the work start signal, the start signal receiving unit 34 stores the start of work in the work areas 1a to 1c in the storage unit 24 as the work status.

The end signal receiving unit 35 receives the notification work end signal transmitted from the work terminal device 5. When receiving the work end signal, the end signal receiving unit 35 stores the work end in the work areas 1a to 1c as the work status in the storage unit 24.
The work history receiving unit 36 receives work history information transmitted from the work terminal device 5. The work history recording unit 37 records the received work history information in the storage unit 24.
Note that the processing of step S100 in FIG. 3 corresponds to the processing of the reception intensity setting unit 30, the set time presentation unit 31, and the area information generation unit 32. The processes of steps S101 and S104 correspond to the processes of the area information transmitting unit 33 and the start signal receiving unit 34, respectively. The processing in step S110 corresponds to the processing of the end signal receiving unit 35, the work history receiving unit 36, and the work history recording unit 37.

(Management terminal device setting process)
Next, area information setting processing in the management terminal device 3 will be described. FIG. 6 is a flowchart of the area information setting process in the management terminal device 3 according to the first embodiment. Hereinafter, the setting process in the work area 1a is exemplified, but the area information may be set in the work areas 1b and 1c by the same process.
In step S120, the reception intensity setting unit 30 specifies an identification signal of the wireless transmitter 6a installed in the work area 1a to be received. In step S121, the reception intensity setting unit 30 determines whether the short-range communication unit 21 has received the designated identification signal, that is, the identification signal of the wireless transmitter 6a. If the designated identification signal is not received (No in step S121), the setting process ends. When the designated identification signal is received (Yes in step S121), the process proceeds to step S122.

  In step S122, the reception intensity setting unit 30 detects the reception intensity of the received identification signal. In step S123, the reception strength setting unit 30 sets the detected reception strength as an initial value of the setting strength and presents it on the setting screen 50 of the display unit 23. In step S124, the reception strength setting unit 30 determines whether or not a change input of the initial value of the setting strength has been made. If there is no input to change the initial value (No in step S124), the process proceeds to step S126. In this case, the initial value is set as the setting intensity corresponding to the wireless transmitter 6a. If there is an initial value change input (Yes in step S124), the process proceeds to step S125. In step S125, the reception strength setting unit 30 sets the input value of the change input as the setting strength corresponding to the wireless transmitter 6a. Thereafter, the process proceeds to step S126.

  In step S126, the set time presentation unit 31 calculates an initial value of the set time according to the reception intensity of the identification signal received by the short-range communication unit 21. In step S127, the set time presentation unit 31 presents the initial value of the set time on the setting screen 50. In step S128, the set time presentation unit 31 determines whether or not a change input for changing the set time has been performed. If a change input has been made (Yes in step S128), the process proceeds to step S129. If no change input is made (No in step S128), the process proceeds to step S130.

  In step S129, the set time presentation unit 31 sets the input value of the change input as the set time corresponding to the wireless transmitter 6a. Thereafter, the process proceeds to step S130. In step S <b> 130, the set time presentation unit 31 determines whether or not a fixed input of the set time has been performed. If the confirmation input is not performed (No in step S130), the process returns to step S128. When the confirmation input is performed (Yes in step S130), the set time presentation unit 31 confirms the set time. Thereafter, the process proceeds to step S131. When the confirmation input is made without any change input, the initial value is set as the set time. In step S131, the area information generation unit 32 generates area information.

(Configuration of work terminal device)
Next, the configuration of the work terminal device 5 will be described. Please refer to FIG. As the work terminal device 5, a smartphone or a mobile phone can be employed. However, the work terminal device 5 is not limited to these. The work terminal device 5 is portable, has a short-range wireless communication function for receiving the identification signal of the wireless transmitter 6, a communication function with the management terminal device 3, and an information processing function, and stores an application program. Other devices that can realize these functions may be used.

The work terminal device 5 includes a communication unit 70, a short-range communication unit 71, an operation unit 72, a display unit 73, a storage unit 74, and a control unit 75.
The communication unit 70 includes wired and wireless communication interfaces, and is connected to the communication network 10 via a connector or an antenna.
The short-range communication unit 71 includes an interface circuit for performing short-range wireless communication according to a communication method such as iBeacon (trademark) conforming to Bluetooth (registered trademark) LE, for example. The short-range wireless communication range is about several meters to several tens of meters, whereby the short-range communication unit 71 receives the identification signal transmitted from the wireless transmitter 6.

  The operation unit 72 functions as an information input unit, and may include an input button, a touch panel provided on the display screen of the display unit 73, and the like. The operation unit 72 is used for receiving data input and operation input to the work terminal device 5. The display unit 73 functions as a display unit and displays various types of information under the control of the control unit 75. The storage unit 74 includes a nonvolatile memory and / or a hard disk drive device. The storage unit 74 stores various data, application programs, and the like. For example, the storage unit 74 may store area information received from the management terminal device 3 and work history information generated by the work terminal device 5. Further, the storage unit 74 may store a work program 76 that causes the control unit 75 to execute processing for generating work history information of work in the work areas 1a to 1c.

The work program 76 may be recorded on a machine-readable recording medium, read by a medium reading device (not shown), and installed in the storage unit 74. The work program 76 may be downloaded from the communication network 10 via the communication unit 70 and installed in the storage unit 74.
The communication unit 70, the short-range communication unit 71, the operation unit 72, the display unit 73, and the storage unit 74 are connected to the control unit 75. The control unit 75 includes a processor, its peripheral circuits, ROM and RAM. The control unit 75 reads the work program 76 from the storage unit 74 and executes it. Hereinafter, the functional configuration of the control unit 75 will be described.

The control unit 75 includes an area information reception unit 80, a start signal transmission unit 81, an accumulation processing unit 82, a work determination unit 83, an end signal transmission unit 84, and a history information transmission unit 85. The work program 76 is a command for causing the control unit 75 to execute the processes of the area information receiving unit 80, the start signal transmitting unit 81, the accumulation processing unit 82, the work determining unit 83, the end signal transmitting unit 84, and the history information transmitting unit 85. including.
The area information receiving unit 80 receives area information transmitted from the management terminal device 3. The area information receiving unit 80 stores area information in the storage unit 74. Thereby, the storage unit 74 stores the work areas 1a to 1c and the identification signals of the wireless transmitters 6a to 6c in association with each other. That is, the storage area 74 stores the work areas 1a to 1c and the wireless transmitters 6a to 6c in association with each other. Further, the storage unit 74 stores the set intensity and set time of the work areas 1a to 1c and the work areas 1a to 1c in association with each other. Thereby, the setting intensity and setting time of the work areas 1a to 1c and the wireless transmitters 6a to 6c are stored in the storage unit 74 in association with each other.

The start signal transmission unit 81 transmits a work start signal to the management terminal device 3 when the worker 4 performs a start notification operation.
When receiving the identification signal of the wireless transmitter 6 in the work area 1 where the worker 4 is working, the accumulation processing unit 82 compares the reception strength of the identification signal with the set strength corresponding to the wireless transmitter 6. When the reception strength is equal to or higher than the set strength, the accumulation processing unit 82 accumulates the reception time by adding the current reception time to the cumulative reception time of the identification signal of the wireless transmitter 6. When the reception strength is less than the set strength, the accumulation processing unit 82 does not accumulate the reception time of the identification signal of the wireless transmitter 6.

  For example, when the worker 4 is working in the work area 1a, when the accumulation processing unit 82 receives the identification signal of the wireless transmitter 6a, the accumulation intensity of the identification signal and the setting corresponding to the wireless transmitter 6a Compare strength. When the reception intensity is equal to or higher than the set intensity, the accumulation processing unit 82 accumulates the reception time of the identification signal of the wireless transmitter 6a. When the reception intensity is less than the set intensity, the accumulation processing unit 82 does not accumulate the reception time of the identification signal of the wireless transmitter 6a. Similarly, in the work areas 1b and 1c, the reception times of the identification signals of the wireless transmitters 6b and 6c may be accumulated, respectively.

The work determination unit 83 determines whether or not the accumulated reception time of the wireless transmitter 6 is equal to or longer than a set time corresponding to the wireless transmitter 6. When the accumulated reception time is equal to or longer than the set time, the work determination unit 83 determines that the work in the work area 1 has been performed.
For example, when the worker 4 is working in the work area 1a, the work determination unit 83 determines whether or not the accumulated reception time of the wireless transmitter 6a is equal to or longer than a set time corresponding to the wireless transmitter 6a. To do. When the accumulated reception time is equal to or longer than the set time, the work determination unit 83 determines that the work in the work area 1a has been performed.

The work determination unit 83 may display the work status in which the work in the work area 1 is reflected on the display unit 73. FIG. 8A and FIG. 8B are explanatory diagrams of an example of the work status screen 100 displayed on the display unit 73.
The work status screen 100 has a work area display area 101 and a work status display area 102. In the work area display area 101, names of the work areas 1a to 1c are displayed. The work status display area 102 displays whether or not work has been performed for each of the work areas 1a to 1c. For example, a state where the work is not performed is represented by parentheses [] sandwiching a blank, and a state where the work is performed is represented by parentheses [●] sandwiching a circle. For example, the example of (a) of Drawing 8 shows the state where work is not carried out in any of work areas 1a-1c. The example of FIG. 8B shows a state in which work is performed only in the work area 1a.

In addition, when the work determination unit 83 determines that the work in the work area 1 has been performed, the work determination unit 83 stores the current time as work history information. That is, the work determination unit 83 stores the time at which the work in the work area 1 is considered to be performed as work history information.
FIG. 9 is a diagram illustrating a first example of work history information. The work history information includes information elements “work area” and “end time”. The information element “work area” designates work area 1. The information element “end time” indicates a time at which it is considered that the work in the designated work area 1 is performed. The work determination unit 83 records each time when the work is performed as the end time when the work is finished in each of the work areas 1a to 1c.
For example, in the example of the work history information of FIG. 9, the end time of the work area 1a is “8:10:45”. The work in the work areas 1b and 1c has not been completed, and the end time has not been recorded. Here, for convenience of explanation, only the time is shown, but it is preferable that the work history information includes date information.

On the other hand, when the accumulated reception time is less than the set time, the work determination unit 83 determines that the work in the work area 1a has not been completed, is insufficient, or is not performed. In the case of the work areas 1b and 1c, execution of work may be similarly determined.
The end signal transmission unit 84 transmits a notification work end signal to the management terminal device 3. The history information transmission unit 85 transmits work history information to the management terminal device 3.

  Note that the processes in steps S102 and S103 in FIG. 3 correspond to the processes in the area information receiving unit 80 and the start signal transmitting unit 81, respectively. The processing of steps S105 and S108 corresponds to the processing of the accumulation processing unit 82. The processing of steps S106 and S107 corresponds to the processing of the work determination unit 83. The process of step S109 corresponds to the process of the end signal transmission unit 84 and the history information transmission unit 85.

(Reception processing of identification signal in work terminal device)
Next, the reception process of the identification signal in the work terminal device 5 will be described. FIG. 10 is a flowchart of an identification signal reception process setting process in the work terminal device 5 according to the first embodiment. Hereinafter, although the reception process in the work area 1a is illustrated, the same reception process may be performed also in the work areas 1b and 1c.

  When the short-range communication unit 71 receives the identification signal of the wireless transmitter 6a, in step S140, the accumulation processing unit 82 compares the reception strength of the identification signal with the set strength corresponding to the wireless transmitter 6a. If the reception intensity is less than the set intensity (No in step S140), the reception process ends. If the reception strength is equal to or higher than the set strength (Yes in step S140), the process proceeds to step S141. In step S141, the accumulation processing unit 82 accumulates the reception time by adding the current reception time to the accumulated reception time of the identification signal of the wireless transmitter 6a.

In step S142, the work determination unit 83 determines whether or not the accumulated reception time of the wireless transmitter 6a is equal to or longer than a set time corresponding to the wireless transmitter 6a. If the accumulated reception time is less than the set time (No in step S142), the reception process ends. If the accumulated reception time is equal to or longer than the set time (Yes in step S142), the process proceeds to step S143.
In step S143, the work determination unit 83 determines that the work in the work area 1a has been performed. In step S144, the work determination unit 83 stores the current time as work history information.

(Effect of 1st Embodiment)
(1) The management terminal device 3 calculates a set time, which is a threshold used for determining whether or not work is performed, according to the reception strength of the identification signal of the wireless transmitter 6 received in the work area 1. The reception intensity varies depending on the distance from the wireless transmitter 6, and the work amount in the work area 1 varies depending on the size of the work area 1. Therefore, since the set time calculated in this way reflects the work amount of the work area 1, it can be used as an index for evaluating whether or not the work is performed in the work area 1. By using such a set time for determination of work execution, the reliability of the work execution record can be improved.
Further, by calculating a set time reference value reflecting the work amount in the work area 1 and presenting it to the management terminal device 3, it is possible to prevent setting mistakes caused by an unfamiliar work manager 2. Moreover, the set time set in different work areas can be leveled.

(2) The work terminal device 5 accumulates the reception time of the identification signal of the wireless transmitter 6 received in the work area 1, and when the accumulated reception time is equal to or longer than the set time corresponding to the wireless transmitter 6 1 is determined to be performed. For this reason, it is possible to determine whether or not the worker 4 carrying the work terminal device 5 has stayed in the work areas 1a to 1c for the set time set for each of the work areas 1a to 1c. As a result, the reliability of the work execution record can be improved.
(3) The work terminal device 5 displays the work execution determination result on the display unit 73. For this reason, the worker 4 can determine whether or not the amount of work performed is sufficient.

(Modification of the first embodiment)
Hereinafter, modifications of the first embodiment will be described.
(1) The management terminal device 3 may be a stationary computer, an information processing device, or a computer. In this case, the reception strength of the identification signal of the wireless transmitter 6 in the work area 1 is detected by using another portable terminal device having a short-range communication function with the wireless transmitter 6, for example, the work terminal device 5. It's okay. The management terminal device 3 may acquire information related to the reception strength of the identification signal from the portable terminal device used for detection. The set time presentation unit 31 may set the set time of the work area 1 according to information acquired from the portable terminal device.

(2) The set time presentation unit 31 may calculate the initial value of the set time so that the longer the received intensity, the longer the set time. For example, it is assumed that the transmission intensity of the wireless transmitter 6 is set higher in advance as the work area 1 is wider. In this case, if the reception intensity is detected while keeping the distance between the management terminal device 3 and the wireless transmitter 6 constant in any work area 1, the reception intensity becomes higher as the work area 1 is wider. Therefore, the higher the reception intensity, the longer the initial value, and the wider the work area 1, the longer the initial value.
The set time presentation unit 31 may determine the set time according to the set strength set by the reception strength setting unit 30.

  (3) The history information transmission unit 85 of the work terminal device 5 transmits the history information to the management terminal device 3 every time the work determination unit 83 determines that each work in the work areas 1a to 1c has been performed. Also good. By transmitting the history information every time work for each work area 1 is performed, the work manager 2 can check the progress of work for each work area 1.

  (4) The accumulation processing unit 82 of the work terminal device 5 may store the accumulated reception time accumulated in the work area 1 in association with the work area 1 as work history information. Further, the cumulative processing unit 82 of the work terminal device 5 may display the cumulative reception time on the display unit 73. The history information transmission unit 85 may transmit the accumulated reception time accumulated in the work area 1 to the management terminal device 3 as work history information. In this case, it is not necessary to determine whether or not the accumulated reception time of the wireless transmitter 6 is equal to or longer than the set time corresponding to the wireless transmitter 6, and the work determination unit 83 may be omitted.

(Second Embodiment)
Next, a second embodiment will be described. When receiving the identification signal from the wireless transmitter 6, the work terminal device 5 of the second embodiment transmits the reception result of the identification signal to the management terminal device 3. Based on the reception result transmitted from the work terminal device 5, the management terminal device 3 compares the accumulated reception time when the identification signal is received by the work terminal device 5 with the set time corresponding to the wireless transmitter 6. To do. When the accumulated reception time is equal to or longer than the set time, the management terminal device 3 determines that the work in the work area 1 in which the wireless transmitter 6 is installed has been performed.

(Configuration of work terminal device)
The configuration of the work terminal device 5 will be described. Please refer to FIG. Constituent elements similar to those of the first embodiment shown in FIG. The control unit 75 includes a reception result transmission unit 86. The work program 76 includes a command for causing the control unit 75 to execute the process of the reception result transmission unit 86.
The reception result transmission unit 86 transmits a reception result signal indicating the reception result of the identification signal of the wireless transmitter 6 by the short-range communication unit 71 to the management terminal device 3. The reception result signal may be a signal indicating that the short-range communication unit 71 has received the identification signal, for example. The reception result transmission unit 86 may transmit the reception result signal to the management terminal device 3 every time the short-range communication unit 71 receives the identification signal.
The reception result transmission unit 86 may transmit the reception result signal to the management terminal device 3 at a transmission cycle T1 that is longer than the transmission cycle T0 of the identification signal of the wireless transmitter 6. In this case, the reception result signal may include the number of times of reception of the identification signal during the transmission cycle T1. Since the transmission cycle T1 of the reception result signal is longer than the transmission cycle T0 of the identification signal, the load on the management terminal device 3, the work terminal device 5, and the communication network 10 can be reduced.

(Configuration of management terminal device)
Next, the configuration of the management terminal device 3 will be described. Please refer to FIG. Constituent elements similar to those of the first embodiment shown in FIG. The control unit 25 includes a reception result reception unit 38, an accumulation processing unit 39, and a work determination unit 40. The management program 27 includes a command for causing the control unit 25 to execute the processes of the reception result receiving unit 38, the accumulation processing unit 39, and the work determination unit 40.
The reception result receiving unit 38 receives a reception result signal transmitted from the work terminal device 5.

  When the reception result reception unit 38 receives the reception result signal, the accumulation processing unit 39 accumulates the reception time by adding the reception time to the accumulated reception time of the identification signal of the wireless transmitter 6. For example, when the reception result signal is transmitted every time the short-range communication unit 71 receives the identification signal, the accumulation processing unit 39 causes the wireless transmitter 6 to receive the reception result signal every time the reception result reception unit 38 receives the reception result signal. The reception time may be accumulated by adding the transmission period T0 of the identification signal to the accumulated reception time. For example, when the reception result signal includes the number of times of reception of the identification signal, the accumulation processing unit 39 may accumulate the reception time by adding the product of the transmission period T0 and the number of receptions to the accumulated reception time.

The work determination unit 40 determines whether or not the accumulated reception time of the identification signal of the wireless transmitter 6 is equal to or longer than a set time corresponding to the wireless transmitter 6. When the accumulated reception time is equal to or longer than the set time, the work determination unit 40 determines that the work in the work area 1 in which the wireless transmitter 6 is installed has been performed. The work determination unit 40 may display the work area 1 where the work has been performed on the display unit 23. As a result, the work execution status displayed on the display unit 23 is updated each time work in each work area 1 is performed.
Further, when the work determination unit 40 determines that the work in the work area 1 has been performed, the work determination unit 40 stores the current time as work history information of the work area 1 in which the wireless transmitter 6 is installed. Further, when the work determination unit 40 determines that the work in the work area 1 has been performed, the work determination unit 40 may transmit information notifying that the work in the work area 1 has been performed to the work terminal device 5. .

(Working sequence in the second embodiment)
Next, a work sequence in the work support system of the second embodiment will be described with reference to FIG. The processes in steps S200 to S205 are the same as the processes in steps S100 to S105 in the first embodiment shown in FIG.
In step S206, the reception result transmission unit 86 of the work terminal device 5 transmits a reception result signal indicating the reception result of the identification signal of the wireless transmitter 6a in the first work area 1a to the management terminal device 3. In step S <b> 207, the reception result receiving unit 38 of the management terminal device 3 receives the reception result signal transmitted from the work terminal device 5. When the reception result receiving unit 38 receives the reception result signal, the accumulation processing unit 39 accumulates the reception time of the identification signal of the wireless transmitter 6a.

In step S208, the work determination unit 40 of the management terminal device 3 determines whether or not the accumulated reception time of the identification signal of the wireless transmitter 6a is equal to or longer than the set time corresponding to the wireless transmitter 6a. If the accumulated reception time is less than the set time (No in step S208), the process returns to step S207. If the accumulated reception time is equal to or longer than the set time (Yes in step S208), the process proceeds to step S209.
In step S209, the work determination unit 40 of the management terminal device 3 determines that the work in the work area 1a has been performed. The work determination unit 40 stores the current time as work history information of the work area 1a.

Thereafter, when the work in the work area 1a is completed, the worker 4 enters the next work area 1b and starts work. In step S210, the short-range communication unit 21 of the work terminal device 5 receives the identification signal from the wireless transmitter 6b in the work area 1b. Thereafter, similarly to the processing in steps S205 to S209 in the case of the work area 1a, accumulation of reception time, determination of work execution, and generation of work history information are performed. The same applies to the work area 1c next to the work area 1b.
When the work in the work area 1c is completed, the end signal transmission unit 84 of the work terminal device 5 transmits a work end signal to the management terminal device 3 in step S211. In step S212, when receiving the work end signal, the end signal receiving unit 35 of the management terminal device 3 stores the work end in the work areas 1a to 1c as the work status.

(Effect of 2nd Embodiment)
(1) The management terminal device 3 compares the accumulated reception time when the identification signal is received by the work terminal device 5 with the set time corresponding to the wireless transmitter 6. The management terminal device 3 determines that work in the work area 1 in which the wireless transmitter 6 is installed has been performed when the accumulated reception time is equal to or greater than the set time. For this reason, it is possible to determine whether or not the worker 4 carrying the work terminal device 5 has stayed in the work areas 1a to 1c for the set time set for each of the work areas 1a to 1c. As a result, the reliability of the work execution record can be improved.
(2) The management terminal device 3 displays the determination result of the work execution on the display unit 73. For this reason, every time work for each work area 1 is carried out, the work execution status displayed on the display unit 23 is updated. As a result, the work manager 2 can check the progress of work in units of work areas.

(Modification of the second embodiment)
Hereinafter, modifications of the second embodiment will be described.
(1) The work terminal device 5 may include an accumulation processing unit 82. The reception result signal may include the reception time accumulated by the accumulation processing unit 82. The work determination unit 40 of the management terminal device 3 may determine that the work has been performed when the accumulated reception time included in the reception result signal is equal to or longer than the set time.
(2) The cumulative processing unit 39 of the management terminal device 3 may display the cumulative reception time on the display unit 23. By displaying the accumulated reception time, the work manager 2 can check the progress of work in each of the work areas 1a to 1c. The cumulative processing unit 39 may display the cumulative reception time itself on the display unit 23, and express the cumulative reception time by displaying the ratio of the cumulative reception time to the set time corresponding to the wireless transmitter 6. Also good.

(Third embodiment)
Next, a third embodiment will be described. Even if the cumulative reception time of the identification signal is equal to or longer than the set time, the work actually performed is not always sufficient. For example, the worker 4 may take a break without permission while staying in the work area 1.
Therefore, the management terminal device 3 according to the third embodiment receives the reference action amount as a reference for each action amount of the work in the work areas 1a to 1c in advance in the work areas 1a to 1c, respectively. It is calculated according to the reception intensity of the identification signal.
On the other hand, the work terminal device 5 of the third embodiment detects the amount of action of the worker 4 in accordance with the movement that occurs in the work terminal device 5. The work terminal device 5 records the accumulation of action amounts detected while the reception times of the identification signals are accumulated in the work areas 1a to 1c, respectively, as the action amount of work in the work areas 1a to 1c.
The management terminal device 3 compares the action amount recorded by the work terminal device 5 with the reference action amount, and determines the work abnormality in the work areas 1a to 1c.

(Working sequence in the third embodiment)
Next, a work sequence in the work support system of the third embodiment will be described with reference to FIG.
In step S400, the work manager 2 performs area information setting processing and reference action amount setting processing in the management terminal device 3 prior to work. The area information setting process is the same as the process in the first embodiment. The reference action amount setting process will be described later with reference to FIGS. The management terminal device 3 generates action amount information representing the set reference action amount.

(A) of FIG. 15 is an example of action amount information. The action amount information includes information elements “work area”, “identification signal”, and “reference action amount”. The information element “work area” designates work area 1. The information element “identification signal” indicates the identification signal of the wireless transmitter 6 installed in the designated work area 1. The information element “reference action amount” indicates a reference action amount set for the designated work area 1. In the example of the behavior amount information in FIG. 15A, the reference behavior amount set for the work area 1a is “300”.
The action amount information may be part of the area information. That is, the action amount information may be generated integrally with the area information. (B) of FIG. 15 is a figure which shows the example of the area information produced | generated integrally with action amount information. The information element shown in (b) of FIG. 15 is the same as the information element shown in FIG. 2 and the information element shown in (a) of FIG.

Refer to FIG. The processing from step S401 to step S405 is the same as the processing from step S101 to step S105 in FIG. If the reception strength of the identification signal of the wireless transmitter 6a is equal to or higher than the set strength corresponding to the wireless transmitter 6a, the work terminal device 5 detects the behavior of the worker 4 detected within the reception time of the identification signal in step S406. Accumulate the amount. That is, the work terminal device 5 accumulates the action amount of the worker 4 detected while accumulating the reception time of the identification signal. In the following description, the accumulated action amount may be referred to as “accumulated action amount”.
In step S407, the work terminal device 5 determines whether or not the accumulated reception time is equal to or longer than the set time corresponding to the wireless transmitter 6a. When the accumulated reception time is less than the set time (No in step S407), the work terminal device 5 determines that the work in the work area 1a has not been completed, is insufficient, or is not performed. Thereafter, the process returns to step S405. If the accumulated reception time is equal to or longer than the set time (Yes in step S407), the work terminal device 5 determines that the work in the work area 1a has been performed. Thereafter, the process proceeds to step S408.

  In step S408, the work terminal device 5 stores the current time and the accumulated action amount as work history information. FIG. 16 is a diagram illustrating a second example of work history information. The work history information includes information elements “work area”, “end time”, and “cumulative action amount”. The information elements “work area” and “end time” are the same as the information elements “work area” and “end time” of the work history information shown in FIG. The information element “cumulative action amount” indicates the accumulated action amount of the worker 4 detected while the reception time of the identification signal is accumulated in the designated work area 1. In the example of the work history information in FIG. 16, the cumulative action amount in the work area 1a is “305”. Further, the work in the work areas 1b and 1c has not been completed, and the cumulative action amount has not been recorded.

When the work in the work area 1a is completed, the worker 4 enters the next work area 1b and starts work. In step S409, the work terminal device 5 receives the identification signal from the wireless transmitter 6b in the work area 1b. Thereafter, similarly to the processing in steps S405 to S408 in the case of the work area 1a, the accumulation of the reception time and the action amount, the determination of the work execution, and the generation of work history information are performed. The same applies to the work area 1c next to the work area 1b.
Steps S410 and S411 are the same as steps S109 and S110 in FIG.

  In step S412, the management terminal device 3 compares the cumulative action amount accumulated in the work areas 1a to 1c with the reference action amount set for the work areas 1a to 1c. The management terminal device 3 detects a work abnormality based on the comparison result. If an abnormality is detected, the management terminal device 3 notifies the work manager 2 of the abnormality in step S413.

(Configuration of management terminal device)
Next, the configuration of the management terminal device 3 will be described. Refer to FIG. Constituent elements similar to those of the first embodiment shown in FIG. The control unit 25 includes a behavior amount calculation unit 41, a behavior amount information generation unit 42, a comparison unit 43, and a notification unit 44. The management program 27 includes a command for causing the control unit 25 to execute the processes of the behavior amount calculation unit 41, the behavior amount information generation unit 42, the comparison unit 43, and the notification unit 44.

The behavior amount calculation unit 41 calculates an initial value of the reference behavior amount according to the reception strength detected by the reception strength setting unit 30, that is, the reception strength of the identification signal received by the short-range communication unit 21.
For example, it is assumed that the transmission intensity of the wireless transmitter 6 is set to be constant between the work areas 1a to 1c. In this case, the behavior amount calculation unit 41 may calculate a larger reference behavior amount as the reception intensity is lower.
Further, for example, a case is assumed where the transmission intensity of the wireless transmitter 6 is set higher in advance as the work area 1 is wider. In this case, a higher reference action amount may be calculated as the reception intensity is higher.

The behavior amount calculation unit 41 presents the calculated initial value of the reference behavior amount on the display unit 23 of the management terminal device 3. FIG. 18 is an explanatory diagram of a second example of the setting screen 50 displayed on the display unit 23. Components similar to those of the first embodiment shown in FIGS. 5A and 5B are denoted by the same reference numerals. The setting screen 50 includes a reference action amount display area 58 and a reference action amount slider 59.
Before the reference action amount slider 59 is operated, an initial value of the reference action amount is presented in the reference action amount display area 58. By operating the reference action amount slider 59, the work manager 2 can input change of the reference action amount. Further, by operating the registration button 57, the work manager 2 can perform a fixed input of the reference action amount. The operation unit 22 receives the change input and the confirmation input as input operations for the reference action amount.
An input value of the change input is set as a reference action amount by performing a definite input after the change input. The initial value is set as the reference action amount by performing the definite input without performing the change input. The behavior amount calculation unit 41 receives the input of the reference behavior amount from the operation unit 22 and outputs the reference behavior amount set for each of the work areas 1 a to 1 c to the behavior amount information generation unit 42. The behavior amount information generation unit 42 generates behavior amount information based on the reference behavior amount received from the behavior amount calculation unit 41. The behavior amount information generation unit 42 stores the behavior amount information in the storage unit 24.

The comparison unit 43 compares the cumulative action amount of the work areas 1a to 1c recorded as the work history information in the storage unit 24 with the reference action amount of the work areas 1a to 1c recorded as the action amount information. The comparison unit 43 detects work abnormalities in the work areas 1a to 1c based on these comparison results. For example, work abnormality may be detected when the difference between the cumulative action amount and the reference action amount is not within a predetermined allowable range.
When the abnormality is detected, the notification unit 44 notifies the work manager 2 of the abnormality. For example, the notification unit 44 may display the work area 1 where the abnormality is detected on the display unit 23.

  The process of step S400 in FIG. 14 corresponds to the processes of the reception intensity setting unit 30, the set time presentation unit 31, the area information generation unit 32, the behavior amount calculation unit 41, and the behavior amount information generation unit. The processes of steps S412 and S413 correspond to the processes of the comparison unit 43 and the notification unit 44, respectively.

(Management terminal device setting process)
Next, setting processing of area information and work amount information in the management terminal device 3 will be described. FIG. 19 is a flowchart of setting processing of area information and work amount information in the management terminal device 3 according to the first embodiment. Hereinafter, the setting process in the work area 1a is exemplified, but the area information and the work amount information may be set in the work areas 1b and 1c by the same process.
The processing from step S420 to step S426 is the same as the processing from step S120 to step S126 in FIG.

In step S427, the behavior amount calculation unit 41 calculates an initial value of the reference behavior amount in the work area 1a according to the reception strength of the identification signal of the wireless transmitter 6a received by the short-range communication unit 21. In step S428, the set time presentation unit 31 and the behavior amount calculation unit 41 present the initial value of the set time and the initial value of the reference behavior amount on the setting screen 50.
In step S429, the set time presentation unit 31 determines whether or not a change input for changing the set time has been performed. Further, the behavior amount calculation unit 41 determines whether or not a change input for changing the reference behavior amount has been performed. If a change input has been made (Yes in step S429), the process proceeds to step S430. If no change input is made (No in step S429), the process proceeds to step S431.

When the change input of the set time is performed, in step S430, the set time presentation unit 31 sets the input value of the change input as the set time corresponding to the wireless transmitter 6a. When the change input of the reference action amount is performed, the action amount calculation unit 41 sets the input value of the change input as the reference action amount of work in the work area 1a. Thereafter, the process proceeds to step S431.
In step S431, the set time presentation unit 31 and the action amount calculation unit 41 determine whether or not a fixed input of the set time and the reference action amount has been performed. If the confirmation input is not performed (No in step S431), the process returns to step S429. When the confirmation input is performed (Yes in step S431), the set time presentation unit 31 and the action amount calculation unit 41 determine the set time and the reference action amount. If a final input is made without changing the reference action amount once, the initial value is set as the reference action amount. Thereafter, the process proceeds to step S432.
In step S432, the area information generation unit 32 generates area information. In step S433, the behavior amount information generation unit 42 generates behavior amount information.

(Configuration of work terminal device)
Next, the configuration of the work terminal device 5 will be described. Refer to FIG. Constituent elements similar to those of the first embodiment shown in FIG. The work terminal device 5 includes a behavior amount sensor 78. The control unit 75 includes a behavior amount detection unit 91 and a behavior amount recording unit 92. The work program 76 includes instructions for causing the control unit 75 to execute the processes of the behavior amount detection unit 91 and the behavior amount recording unit 92.
The behavior amount sensor 78 detects a movement that occurs in the work terminal device 5. The behavior amount sensor 78 may be a vibration sensor that detects, for example, vibration applied to the work terminal device 5 as a motion generated in the work terminal device 5. Further, for example, the behavior amount sensor 78 may be an acceleration sensor that detects an acceleration applied to the work terminal device 5 as a motion generated in the work terminal device 5.

The behavior amount detection unit 91 detects the behavior amount of the worker 4 within the reception time of the identification signal of the wireless transmitter 6 according to the movement detected by the behavior amount sensor 78. For example, one unit may be counted as a behavior amount when a motion such as vibration amount or acceleration detected by the behavior amount sensor 78 exceeds a predetermined threshold. If the reception intensity of the identification signal is equal to or higher than the set intensity corresponding to the wireless transmitter 6, the action amount detection unit 91 uses the detected action amount as the action amount of work in the work area 1 in which the wireless transmitter 6 is installed. Accumulate as.
For example, it is assumed that the worker 4 is working in the work area 1a. If the reception strength of the identification signal of the wireless transmitter 6a is equal to or higher than the set strength corresponding to the wireless transmitter 6a, the behavior amount detection unit 91 determines the behavior amount of the worker 4 detected within the reception time of the identification signal. Accumulated as the amount of work activity in the work area 1a.

For example, the behavior amount detection unit 91 may accumulate the behavior amount by adding the behavior amount detected during the most recent transmission cycle T0 of the reception time of the identification signal to the accumulated behavior amount. In addition, for example, the behavior amount detection unit 91 adds a predetermined amount to the cumulative behavior amount if the detected behavior amount is equal to or greater than the threshold during the transmission cycle T0 nearest to the reception time of the identification signal. If the detected action amount is less than the threshold, the action amount may be accumulated by not adding to the accumulated action amount.
The behavior amount recording unit 92 records the accumulated behavior amount accumulated by the behavior amount detection unit 91 for each of the work areas 1a to 1c as work history information.

  Note that the process of step S406 in FIG. 14 corresponds to the process of the behavior amount detection unit 91. The process of step S408 corresponds to the process of the work determination unit 83 and the action amount recording unit 92.

(Reception processing of identification signal in work terminal device)
Next, the reception process of the identification signal in the work terminal device 5 will be described. FIG. 21 is a flowchart of the setting process of the reception process of the identification signal in the work terminal device 5 according to the third embodiment. Hereinafter, although the reception process in the work area 1a is illustrated, the same reception process may be performed also in the work areas 1b and 1c.

The processing in steps S440 and S441 is the same as the processing in steps S140 and S141 shown in FIG.
In step S442, the action amount is accumulated by adding the action amount detected within the current reception time to the accumulated action amount of the work area 1a in which the wireless transmitter 6a is installed.
The processes in steps S443 and S444 are the same as the processes in steps S142 and S143 shown in FIG.
In step S445, the work determination unit 83 stores the current time as work history information. The action amount recording unit 92 records the accumulated action amount as work history information.

(Effect of the third embodiment)

By using such a reference action amount for determination of work abnormality, the reliability of work execution records can be improved.
In addition, by calculating a reference action amount that reflects the amount of work in the work area 1 and presenting it to the management terminal device 3, it is possible to prevent setting mistakes caused by an unfamiliar work manager 2. In addition, it is possible to level the reference action amount set in different work areas.

  (2) The work terminal device 5 detects the amount of action of the worker 4 according to the movement that occurs in the work terminal device 5, and accumulates the amount of action detected while the reception time of the identification signal is accumulated.

For this reason, it is possible to determine whether or not the worker 4 carrying the work terminal device 5 has performed an action commensurate with the work amount scheduled in the work area 1. As a result, the reliability of the work execution record can be improved.
