A case in which it is a range from being stored until the next “0” is stored) will be described. For example, in FIG. 8, two time pack logs are acquired based on the logs. This time pack log specifically stores the item “calling location information”, the item “accuracy”, and information corresponding to each of these items in association with each other, and corresponds to each of these items. The information is information corresponding to the information stored in the equipment position log table 52c.

In addition, in the application display log update processing described below, the control unit 51 of the server 50 specifies the application display log shown in FIG. 8 based on the time pack log. The “app display log” is a log for specifying the position of the material icon (described later) that is actually displayed on the display 12 of the receiving terminal 10.

The information corresponding to the item “approach determination flag” stores information that specifies whether or not the key of each equipment is present near the corresponding equipment at each time. In the form 1, “1” indicating that the key is in the vicinity of the equipment (that is, the equipment is in an operating state), or that the key is not in the vicinity of the equipment (that is, the equipment is not One of "0" indicating that it is in the operating state is stored. Note that a method for determining whether or not the key exists near the equipment will be described later.

Returning to FIG. 2, the key time pack log table 52f is a key time pack log storage unit that stores the key time pack log. The key time pack log table 52f stores each key time pack log based on the information stored in the key position log table 52e in the operation status specifying process described later. The process of acquiring the key time pack log and the specific method of updating the operating status will be described later in the operating status specifying process. Here, the “key time pack log” is a log that is a collection of a plurality of key logs acquired within a predetermined time range, and the key is located near the equipment in the plurality of key logs. Is a log that identifies whether or not there is even one key log indicating. The “plurality of key logs” may include any number of key logs, but in the present embodiment, 10 minutes is regarded as one pack, and a plurality of key logs are included in the 10 minutes. The case will be described. For example, in FIG. 9, three key time pack logs are acquired based on the key log. Specifically, the key time pack log stores an item “judgment ID”, an item “pack approach judgment flag”, and information corresponding to each of these items in association with each other. As the information corresponding to the item “judgment ID”, serial numbers are stored in time sequence of the key time pack log. Further, as the information corresponding to the item “pack approach determination flag”, a key log indicating that the key is located in the vicinity of the equipment (that is, approach determination flag=“1”) is included in the plurality of key logs. There is no "1" indicating that even one exists, or no key log indicating that the key is located in the vicinity of the equipment (that is, the approach determination flag = "1") (that is, the approach determination flag). Either "0" indicating that "= only "0" exists" is stored.

Further, in the operation condition specifying process described later, the control unit 51 of the server 50 specifies the operation status shown in FIG. 9 based on the key time pack log. The “operating status” is information for identifying whether the equipment is operating (operating status) or not operating (non-operating status) at the current time, and in the example of FIG. 9, for example, , "Active" or "non-active" is stored.

Returning to FIG. 2, FIG. 10 is a diagram illustrating information stored in the operation rate table 52g. As shown in FIG. 10, the operation rate table 52g stores the items “rank”, “type”, and item “operation rate” and the information corresponding to these items in association with each other.

(Configuration-Key Beacon)
The key beacon 60 is a key transmitter arranged in the vicinity of a key for operating the equipment, and specifically, attaches a key beacon ID for uniquely identifying itself to radio waves to Radio waves are emitted in all directions at 360°. Here, "arranged in the vicinity of the key" means that the beacon 60 is arranged with respect to the key at such a close distance that there is no problem even if the position of the key beacon 60 is equated with the position of the key. Means that the key beacon 60 is attached to the key through a fitting such as a metal fitting or a string, or the key beacon 60 is housed in a common key bag together with the key. Including. This key beacon 30 is arranged by the worker one at a position near each key.

(processing)
Next, the processing executed by the operating condition identification system for equipment according to the first embodiment will be described. In this system for identifying the operating status of equipment, beacon registration processing, server DB updating processing, application display log updating processing, operating status identifying processing, and operating rate calculation processing are executed.

(Processing-Beacon registration processing)
First, the beacon registration process executed by the control unit 17 of the receiving terminal 10 according to the first embodiment will be described. In this beacon registration process, roughly, a worker goes around the construction site while holding the receiving terminal 10, arranges the fixed beacon 20 on the construction site, and receives information about the arranged fixed beacon 20 from the receiving terminal 10. This is a process executed when the touch pad 11 is registered in the drawing DB 18b or the transmission position DB 52a.

Specifically, first, the worker places the fixed beacon 20 on the construction site. Subsequently, the worker registers the beacon ID and the transmission position information of the fixed beacon 20 arranged by himself/herself in the transmission position DB 52a of FIG. The specific method of this registration is arbitrary, and an example thereof will be described below.

First, the control unit 17 displays a beacon registration icon on the display 12, and when a worker presses this icon, the beacon registration mode is set. In this mode, first, the setting of the drawing for which the fixed beacon 20 is to be registered is accepted. Specifically, the control unit 17 displays thumbnails of the drawing information stored corresponding to the item “drawing information” in the drawing DB 18b, and one of the thumbnails is selected by the worker (by tapping or the like). Then, the drawing information is displayed on the display 12. Further, a beacon icon indicating the position of the fixed beacon 20 is displayed in the center of the screen. Then, the control unit 17 receives the movement of the display position of the beacon icon. Specifically, for example, when the pressing of an arrow-shaped beacon movement icon (not shown) displayed on the display 12 is received, the beacon icon may be received in the direction indicated by the arrow, or the beacon icon When a finger slide is received while the display position is pressed by the operator's finger, the beacon icon may be moved along the slide. Then, when the confirmation icon (not shown) is pressed in a state where the beacon icon is moved to the position where the fixed beacon 20 is installed, a window for receiving the input of the beacon ID is displayed. Then, the user inputs the beacon ID while confirming the beacon ID described in the fixed beacon 20, and when the beacon ID is input, it is specified by a known method based on the beacon ID and the position of the beacon icon. It is transmitted to the server 50 in association with the transmission position information and stored in the transmission position DB 52a. Further, the beacon ID input as described above is stored in the information corresponding to the item "beacon ID" of the drawing to be registered in the drawing DB 18b of FIG. This completes the beacon registration process.

(Processing-Server DB update processing)
Next, the server DB update processing executed by the control unit 51 of the server 50 according to the first embodiment will be described. The server DB update process is a process of updating the server DB 52b to the latest one based on the signal (hereinafter, log signal) transmitted from the receiving terminal 10. The server DB update process may be executed at any timing, and may be executed when the server 50 is powered on, for example.

First, when receiving the radio wave from the fixed beacon 20, the receiving terminal 10 identifies the fixed beacon ID attached to the received radio wave (the fixed beacon ID transmitted from the fixed beacon 20). At this time, when radio waves are being received from a plurality of fixed beacons 20, these radio wave intensities are compared, and the fixed beacon 20 having the strongest radio wave intensity (that is, existing closest to the receiving terminal 10 exists). The fixed beacon ID of the fixed beacon 20) is specified. Next, the floor corresponding to the fixed beacon ID thus identified is identified from the drawing DB 18b shown in FIG.

Similarly, when receiving the radio wave from the equipment/material beacon 30, the receiving terminal 10 identifies the equipment/material beacon ID attached to the received radio wave (the equipment/material beacon ID transmitted from the equipment/material beacon 30). Then, the radio field intensity from the equipment beacon 30 is specified by a known method. When the radio wave from the equipment beacon 30 is not received (that is, when the position of the receiving terminal 10 is not within the predetermined distance from the equipment beacon 30), the equipment beacon ID and the radio wave intensity are not specified. Good.

Similarly, when receiving the radio wave from the key beacon 60, the receiving terminal 10 identifies the key beacon ID attached to the received radio wave (the key beacon ID transmitted from the key beacon 60). If the radio wave from the key beacon 60 is not received (that is, the position of the receiving terminal 10 is not within the predetermined distance from the key beacon 60), the key beacon ID need not be specified.

Then, in addition to the time stamp of the transmission time and the terminal ID of the receiving terminal 10 itself, the receiving terminal 10 further indicates the equipment beacon ID, the fixed beacon ID, the key beacon ID, the floor, and the radio field intensity identified as described above. The attached log signal is created and transmitted to the server 50 by a known method. Such a transmission process by the receiving terminal 10 may be executed at an arbitrary timing, for example, may be executed at a predetermined interval (for example, an interval of 5 seconds). Then, a log signal is transmitted from the plurality of receiving terminals 10 to the server DB 52b by performing such a transmitting process similarly by the plurality of receiving terminals 10.

Then, the control unit 51 of the server 50 sequentially updates the server DB 52b each time the log signal from the receiving terminal 10 is received. Specifically, the information corresponding to the item "time" is updated based on the time stamp included in the received log signal, and the information corresponding to the item "terminal ID" is updated based on the terminal ID included in the log signal. Then, the information corresponding to the item “material beacon ID” is updated based on the equipment beacon ID included in the log signal, and the information corresponding to the item “fixed beacon ID” is updated based on the fixed beacon ID included in the log signal. Is updated, the information corresponding to the item “key beacon ID” is updated based on the key beacon ID included in the log signal, and the information corresponding to the item “floor” is updated based on the floor included in the log signal, By referring to the transmission position DB 52a, the transmission position information corresponding to the fixed beacon ID included in the log signal is specified, the information corresponding to the item "transmission position information" is updated based on the specified transmission position information, and the log The information corresponding to the item "accuracy" is updated based on the radio wave reception intensity included in the signal. As a method of obtaining accuracy, for example, it may be specified by referring to an accuracy specifying table (not shown) that stores the radio wave reception intensity and the accuracy in association with each other, but is not limited to this. Further, in the first embodiment, the accuracy is specified and stored on the server 50 side in this way, but the present invention is not limited to this, and the reception terminal 10 calculates the accuracy and then transmits it by including it in the log signal. The accuracy included in the signal may be stored. Further, the transmission position DB 52a may be provided in the reception terminal 10 so that the transmission position information is specified on the reception terminal 10 side and then added to the log signal and transmitted. This completes the server DB update process.

As described above, the control unit 51 of the server 50 updates the information corresponding to the item “transmission position information” based on the log signal from the receiving terminal 10, and thus the receiving terminal 10 moves with the worker. It functions as a terminal position specifying unit that specifies the position of the receiving terminal 10 that receives the radio wave from the equipment beacon 30 attached to the equipment. Further, by updating the information corresponding to the item “accuracy” based on the log signal, the mutual reception of the reception terminal 10 and the equipment/material beacon 30 based on the electric wave reception intensity from the equipment/material beacon 30 of the reception terminal 10. It functions as an estimated distance specifying unit that specifies an estimated distance between the two. Further, by updating the server DB 52b by associating the information of the item "originating position information" and the information of the item "accuracy" with each other, the position of the receiving terminal 10 specified by the terminal position specifying means and the estimated distance specification at the position. It functions as a log acquisition unit that acquires a log in which the estimated distance specified by the means is associated with each other.

(Process-App display log update process)
Next, the application display log update process executed by the control unit 51 of the server 50 according to the first embodiment will be described. In the following description of the process, the step is abbreviated as “S”. 12 is a flowchart of the app display log update process according to the first embodiment, and FIG. 13 is a flowchart of the app display log update process subsequent to FIG. This application display log update processing is processing for updating the application display log based on the log signal received from the receiving terminal 10 and improving the accuracy of the display position of the equipment icon. The application display log updating process may be executed at any timing, and may be executed when the server 50 is powered on, for example.

In SA1, the control unit 51 of the server 50 determines whether or not a log signal regarding the position of the equipment has been received. A specific method of this determination is arbitrary, for example, referring to the item “material equipment beacon ID” in the server DB 52b, and when information including the material equipment beacon ID is newly stored, a log signal regarding the position of the material equipment is displayed. Determined as acquired. Note that, for example, even if a log signal is received from the receiving terminal 10, if the log signal does not include the equipment beacon ID, there is no information regarding the location of the equipment. Then, the process waits until the log signal regarding the position of the equipment is received (SA1, No), and when the log signal is received (SA1, Yes), the process proceeds to SA2.

In SA2, the control unit 51 of the server 50 adds a log to the equipment position log table 52c (each item other than the item "continuity") based on the received log signal. Specifically, a new log ID is added as information corresponding to the item "log ID" of the equipment position log table 52c, and the item "equipment beacon ID", item "time", and item "transmission" of the added record are added. In the “position information” and the item “accuracy”, information corresponding to the items of the same name in the server DB 52b is sorted and stored in chronological order for each equipment beacon ID.

In SA3, the control unit 51 of the server 50 has elapsed time t1 from the time of the log added in the previous process of SA2 (hereinafter, the previous log) to the log added in the process of SA2 of the present time (hereinafter, the current log). To calculate. Specifically, the time from the time stored in the item “time” of the previous log to the time stored in the item “time” of the current log is calculated by referring to the equipment position log table 52c in FIG. This time is calculated as the elapsed time t1. For example, when L08 in FIG. 8 is the current log, the elapsed time from the previous log (L07) is 25 minutes.

In SA4, the control unit 51 of the server 50 determines whether the elapsed time t1 calculated in SA3 is 1 minute or less. In the first embodiment, 1 minute has been described, but this time is merely an example, and an arbitrary time such as 3 minutes or 5 minutes can be applied. Then, when the elapsed time t1 is not less than 1 minute (SA4, No), the process proceeds to SA5, and when the elapsed time t1 is 1 minute or less (SA4, Yes), the process proceeds to SA7.

In SA5, the control unit 51 of the server 50 sets a 0 flag (a log that is not continuous) in the current log. Specifically, in the first embodiment, "0" is stored as information corresponding to the item "continuity" of the current log of the equipment position log table 52c shown in FIG. For example, when L08 of FIG. 8 is set as the current log, the elapsed time t1 from the previous log (L07) is 25 minutes, and since there is no continuity because one minute or more has elapsed, the item “Continuity” "0" is stored in.

In SA6, the control unit 51 of the server 50 generates a new time pack log. For example, in the above example, the time pack log having the transmission position coordinates (X002, Y001) of the current log (L08) and the accuracy (20) is added to the lower end of the time pack log table 52d of FIG. When a new time pack log (hereinafter "current time pack log") is created in this way, the current time pack log and the previously generated time pack log (hereinafter "previous time pack log") The app display log is updated based on the comparison. The details of updating the application display log will be described later.

In SA7, the control unit 51 of the server 50 sets 1 flag (continuous log) in the current log. Specifically, in the first embodiment, "1" is stored as information corresponding to the item "continuity" of the current log of the equipment position log table 52c shown in FIG.

In SA8, the control unit 51 of the server 50 compares the accuracy of the current log with the other logs up to the log having the 0 flag before the current log. For example, if the current log is L07, the accuracy of the logs up to L05 (that is, L05 and L06) having the 0 flag before L07 is compared with the accuracy of the current log (L07).

In SA9, the control unit 51 of the server 50 determines whether or not the accuracy of the current log is less than or equal to the accuracy of all other compared logs. For example, in the above example, since the accuracy (40) of L07 is not less than the accuracy (30) of L06, it is determined that the accuracy of the current log is not less than or equal to the accuracy of all compared logs. If the accuracy of the current log is less than or equal to the accuracy of all compared logs (SA9, Yes), the current log is a log acquired at a position closer to the equipment than the existing log. It is assumed that the current log is more suitable for indicating the position of the equipment, and the process proceeds to SA10 to overwrite the time pack log with the current log. On the other hand, if the accuracy of the current log is not less than or equal to the accuracy of all compared logs (SA9, No), the existing log is a log acquired at a position closer to the equipment than the current log, It is assumed that the existing log is more suitable for indicating the position of the equipment and materials, and the application display log update process is terminated without overwriting the time pack log.

In SA10, the control unit 51 of the server 50 overwrites the transmission position coordinates of the time pack log. Specifically, the latest time pack log (current time pack log) shown in FIG. 2 is overwritten with the transmission position coordinates and accuracy of the current log. As described above, the control unit 51 of the server 50 overwrites the current time pack log with a log having a smaller accuracy among the plurality of logs, so that the log acquisition unit can perform the predetermined time range (in the first embodiment, As described above in SA4, it functions as a log specifying unit that specifies the time pack log, which is the log indicating the smallest estimated distance, from the plurality of logs acquired in 1 minute).

In SA11, the control unit 51 of the server 50 calculates the elapsed time t2 from the previous time pack log to the current time pack log. For example, referring to the item “time” of the equipment position log table 52c in FIG. 8 in the example of FIG. 8, the elapsed time t2 from the previous time pack log (L02) to the current time pack log (L06) is 5 minutes. I know there is.

In SA12, the control unit 51 of the server 50 determines whether or not the elapsed time t2 calculated in SA11 is a predetermined time (one day in the present embodiment) or more. When the elapsed time t2 is one day or longer (SA12, Yes), the information in the previous time pack log is old and has low usefulness, and therefore the process proceeds to SA15 in order to overwrite it with the current time pack log. On the other hand, when the elapsed time t2 is not longer than 1 day (SA12, No), the information of the previous time pack log is not old, and the one with higher utility is selected from the current time pack log and the previous time pack log. , SA13. In the first embodiment, one day is set as the criterion for determining whether the information in the time pack log is old, but the present invention is not limited to this, and any period can be set, for example, 6 hours or 12 hours. .. In the example of FIG. 8, the elapsed time t2 from the previous time pack log (L02) to the current time pack log (L06) is 5 minutes, and it is determined that it has not yet exceeded one day.

In SA13, the control unit 51 of the server 50 compares the accuracy of the current time pack log with the accuracy of the previous time pack log. For example, the item "accuracy" of the time pack log table 52d shown in FIG. 8 is referred to and compared.

In SA14, the control unit 51 of the server 50 determines whether or not the accuracy of the current time pack log is less than or equal to the accuracy of the previous time pack log. For example, in the example of FIG. 8, since the accuracy of the current time pack log is 30 and the accuracy of the previous time pack log is 10, it is determined that the accuracy is not less than the accuracy of the previous time pack log. When the accuracy of the current time pack log is less than or equal to the accuracy of the previous time pack log (SA14, Yes), the current time pack log is acquired closer to the equipment beacon 30 than the previous time pack log. It is assumed that the log is suitable for indicating the position of the equipment, and the process proceeds to SA15 to update the application display log to the current time pack log. On the other hand, if the accuracy of the current time pack log is not less than or equal to the accuracy of the previous time pack log (SA14, No), the previous time pack log was acquired closer to the equipment beacon 30 than the current time pack log. It is a log and is suitable for representing the position of the equipment, and the application display log is not updated and the previous time pack log is left as it is and the application display log process is terminated. As described above, the control unit 51 of the server 50 specifies the application display log by comparing the time pack logs, and thus the target object position for specifying the position of the equipment based on the time pack log specified by the log specifying unit. Functions as a specifying means.

In SA15, the control unit 51 of the server 50 overwrites the application display log with the current time pack log. That is, when the elapsed time t2 is one day or more (SA12, Yes), the information of the previous time pack log is old and has low usefulness, so that the application display log is overwritten with the current time pack log in order to overwrite with the latest log. To do. When the accuracy of the current time pack log is less than or equal to the accuracy of the previous time pack log (SA14, Yes), the current time pack log is acquired closer to the equipment beacon 30 than the previous time pack log. It is assumed that the log is a log that is suitable for showing the position of the equipment, and the application display log is overwritten with the current time pack log. This is the end of the description of the application display log update process.

(Processing-operation status specifying process)
Next, the operation status specifying process executed by the control unit 51 of the server 50 according to the first embodiment will be described. This operation status specifying process is a process for roughly specifying whether or not the material/device is in operation (operation status) based on the information from the material/device beacon 30 and the key beacon 60. The operation status specifying process may be executed at any timing, and may be executed when the server 50 is powered on, for example. FIG. 14 is a flowchart of the operation status specifying process.

In SB1, the control unit 51 of the server 50 determines whether or not a log signal regarding the position of the key has been received. A specific method of this determination is arbitrary, for example, referring to the item “key beacon ID” of the server DB 52b, and when the information including the key beacon ID is newly stored, the log signal regarding the position of the key is acquired. judge. Then, it waits until the log signal is received (SB1, No), and when the log signal is received (SB1, Yes), the process proceeds to SB2.

In SB2, the control unit 51 of the server 50 adds a log to the key position log table 52e based on the received log signal. Specifically, a new key log ID is added as information corresponding to the item "key log ID" in the key position log table 52e, and the item "material beacon ID", item "time", and item "of the added record are added. The information corresponding to the item of the same name in the server DB 52b is sorted and stored in chronological order for each equipment beacon ID in the "transmission position information". Further, for the item “approach determination flag”, the item “transmission position coordinate” of the server DB 52b is referred to, and the position of the equipment at the peripheral time of the current time (for example, 3 minutes before and after) is extracted to determine the key position. If the position of the materials and equipment is within the predetermined distance, it is determined that they are approaching and "1" is stored, and if they are not within the predetermined distance, it is determined that they are not approaching and "0" is stored. Here, a specific method for determining whether or not the key and the equipment are within a predetermined distance is arbitrary. For example, whether the key beacon 60 and the equipment beacon 30 are in the vicinity of the fixed beacons 20 adjacent to each other. Alternatively, when they exist near the same fixed beacon 20, it may be determined that they are close to each other. However, not limited to such a method, for example, the positions of the key beacon 60 and the equipment beacon 30 are specified based on the radio field intensity from each beacon, the distance between these positions is calculated, and the calculated distance is calculated. It may be determined whether is within a predetermined distance (for example, 5 m).

In SB3, the control unit 51 of the server 50 updates the key time pack log table 52f. Specifically, all the key logs within a predetermined time (10 minutes in the present embodiment) including the added key log are referred to, and if at least one key log with the approach determination flag=1 exists. , "1" is stored in the item "pack approach determination flag" of the key time pack log table 52f, and if there is no key log with the approach determination flag=1, the item "pack approach determination" of the key time pack log table 52f. "0" is stored in the "determination flag".

In SB4, the control unit 51 of the server 50 identifies the operating status of the equipment. Specifically, of the information stored in the key time pack log table 52f updated in SB3, the latest key time pack log (in FIG. 9, the log of the judgment ID 001) is referred to, and the item “pack approach judgment is performed”. If "1" is stored in the flag, it is determined to be "operating", and if "0" is stored, it is determined to be "non-operating". As described above, in the present embodiment, since the operation status is determined by referring to the key time pack log that is a collection of a plurality of key logs, it is possible to erroneously detect the position coordinates due to some reason such as communication failure. It is possible to eliminate erroneous determination caused by determining the operating status based on one key log. This is the end of the operation status specifying process.

(Process-occupancy rate calculation process)
Next, the operation rate calculation process executed by the control unit 51 of the server 50 according to the first embodiment will be described. This occupancy rate calculation process is a process for calculating the occupancy rates of a plurality of materials and equipment to grasp the materials and equipment that are not used and reduce the rental cost of the materials and equipment. The operation rate calculating process may be executed at any timing, and may be executed by the control unit 51 of the server 50 once a day or once a half day, for example.

First, the control unit 51 of the server 50 refers to the key time pack log table 52f, and for each key beacon ID, the number of times the equipment is in the operating state (that is, “1” is set in the item “key time pack log”). The number of stored logs) and the number of logs in which the equipment is not in operation (that is, the number of logs in which “0” is stored in the item “key time pack log”) are calculated. Next, the operating rate of the equipment is calculated based on the following formula (1).
R=n _on /(n _on +n _off )...(1)
here,
R = utilization rate of materials and equipment,
n _on = number of logs that the equipment is operating,
n _off = the number of logs that the equipment is not in operation.
For example, in the example of FIG. 9, n _on =2, n _off =1 and R=2/3 (ie about 66.7%). The operation rate of all materials and equipment is calculated using the same procedure.

Next, the calculated operating rates of the equipment are arranged in descending order, and the operating rate table 52g shown in FIG. 10 is updated. At this time, as the information corresponding to the item “rank”, a number indicating the rank (1 to 5 in the present embodiment) is stored in advance, and with respect to the item “kind”, the materials and equipment for which the operating rate is specified. It may be acquired by referring to the material/material DB 18c based on the material/material beacon ID. As for the item “occupancy rate”, the operation rate of the equipment specified above is stored. In this way, the information stored in the operating rate table 52g is transmitted to the receiving terminal and displayed on the display of the receiving terminal, so that the worker can grasp the operating status at a glance. In addition, since the location and operating rate of materials and equipment can be visualized at the same time, it is possible to easily find and return materials and equipment with low operating rates from a large construction site, improving worker convenience and reducing construction costs. Can be reduced.

(Effect of Embodiment 1)
As described above, according to the operation status identification system for equipment according to the first embodiment, the operation status of the equipment is identified based on the information transmitted from the equipment beacon 30, and thus the position of the equipment is identified. It is possible to easily identify the operating status of the equipment by using the equipment beacon 30 for that purpose, and suppress an increase in construction cost due to the use of an unnecessary number of equipment.

In addition, since the operating status of the equipment is specified based on the radio wave from the key transmitter and the equipment beacon 30, the equipment is operating based on the key of the equipment being located near the equipment. That is, it is possible to easily specify that the convenience is improved.

In addition, since the operating rate of materials and equipment is calculated as the operating status of materials and equipment, the operating status of materials and equipment can be easily grasped as a numerical value, and the operating statuses of multiple materials and equipment can be easily compared, improving convenience. ..

Moreover, the operating rate of the equipment, because the calculation by the equation _{R = n on / (n on} + n off), based on the equipment of the log can easily identify the operation status of the equipment, thereby improving convenience ..

If at least one key log that identifies that the equipment is in operation is included in the plurality of key logs, it means that the equipment is in operation, so it is in operation. Even if there is an omission of acquisition of the key log indicating, the other key log can be supplemented and it can be determined that it is in the operating state, and the specific accuracy is improved.

(Embodiment 2)
Next, an operation status specifying system for equipment according to the second embodiment of the present invention will be described.

Here, the atmospheric pressure sensor constitutes, together with the receiving terminal 10, the fixed beacon 20, the equipment beacon 30 and the key beacon 60, an acquisition means for obtaining operation status information for specifying the operation status of the equipment in the target space. To do. The scaffold 71 of the equipment and materials transmits a detection signal to the equipment and materials beacon 30 by utilizing the fact that the altitude changes (that is, the atmospheric pressure changes) between the time of operation and the time of non-operation. Specifically, the atmospheric pressure at the time of non-operation is recorded in advance, and when the atmospheric pressure different from the recorded atmospheric pressure is determined, it is determined that the scaffold 71 is elevated and is in the operating state, and the detection signal is sent. Send. Not limited to such a method, for example, the atmospheric pressure is regularly measured at a predetermined time interval, and when the atmospheric pressure decreases by a predetermined value or more as compared with the past measured value, the scaffold 71 is moving up and operating. It may be determined that the state is present and the detection signal may be transmitted. The processing executed by the equipment beacon 30 and the receiving terminal 10 after transmitting the detection signal is the same as that in the second embodiment, and thus detailed description thereof will be omitted.

(Effect of Embodiment 3)

In particular, the operating condition specifying program for equipment according to the first embodiment is installed in the server 110 via an arbitrary recording medium or network to substantially configure each unit of the server 110. The “operation status specifying program for materials and equipment” means that the computer is based on the operation status information acquired by the acquisition means for acquiring the operation status information for specifying the operation status of the materials and equipment in the target space. It is a program that causes it to function as a specific means for specifying the operating status of materials and equipment.

(Structure-Server-Data recording unit)
The data recording unit 112 is a recording unit that records programs and various data necessary for the operation of the server 110, and can be configured, for example, in the same manner as the data recording unit 52 of the first embodiment. The data recording unit 112 roughly includes a user DB 112a, a material/material DB 112b, and a drawing DB 112c.

The user DB 112a is a user information storage unit that stores information about a user who owns the reservation terminal 100. FIG. 17 is a diagram illustrating an example of information stored in the user DB 112a. As shown in FIG. 17, the user DB 112a stores items “user ID”, items “name”, items “company name”, and items “password” in association with each other and information corresponding to these items. To do.

Here, as the information corresponding to the item “user ID”, identification information for uniquely identifying each user is stored. For example, like “UID0001” or “UID0002”, the alphabet “UID” and four digits are stored. Identification information composed of numbers is stored. As the information corresponding to the item “name”, the name of the user who owns each reservation terminal 100 is stored. As the information corresponding to the item "company name", the company name of each user's affiliation is stored. As information corresponding to the item “password”, a password for performing login authentication of each user is stored.

Returning to FIG. 16, the material/material DB 112b is a material/material information storage unit that stores information regarding the material/material existing in the target area and information for specifying the reservation status of each material/material. FIG. 18 is a diagram exemplifying information stored in the equipment/materials DB 112b. As shown in FIG. 18, the material/material DB 112b stores the items “material/material ID”, the item “high vehicle name”, the item “floor number”, the item “type”, the item “dedicated”, and the item “reservation”. The information corresponding to each item is stored in association with each other.

Here, as the information corresponding to the item “materials and equipment ID”, information for uniquely identifying each material and equipment (in the fourth embodiment, an aerial work vehicle) is stored, for example, “EID0001”. Identification information composed of the alphabet “EID” and a four-digit number, such as “EID0002” or “EID0002”, is stored. The item “high vehicle name” stores information that identifies the name of each material and equipment. For example, “9m1” indicating the first machine of a 9m aerial work vehicle, and the first machine of a 6m aerial work vehicle. "6m1" and the like shown are stored. As the information corresponding to the item "floor number", information for specifying the floor number for arranging each material and equipment is stored, for example, "1st floor" and "2nd floor" are stored. The item “type” stores information that identifies the type of each equipment, for example, “9m aerial work vehicle” indicating a 9m aerial work vehicle, “6m aerial work vehicle” indicating a 6m aerial work vehicle. "Work vehicle" and the like are stored. As information corresponding to the item “dedicated”, information for identifying whether each equipment is dedicated or non-dedicated (shared) is stored. For example, either “dedicated” or “non-dedicated” is stored. Is stored. Here, “dedicated” indicates a state in which it is necessary to continuously rent materials and equipment from a rental company, and “non-dedicated” does not require continuous rental of materials and equipment from a rental company. Indicates that equipment and materials can be returned to the rental company. As information corresponding to the item “reservation”, information for specifying the reservation status of each equipment is stored. For example, the date and time when the reservation is made, such as “20171114am” and am or pm Information (20171114am indicates the morning of November 14, 2017) and information identifying the user who made the reservation (UID0001 corresponds to the user ID in the user DB 112a in FIG. 17). Is stored in association with each other.

Returning to FIG. 16, the drawing DB 112c is a drawing information storage unit that stores drawing information about a building. For example, from the information stored in the drawing DB 18b of FIG. 4, the item “fixed beacon ID” and information corresponding to this item. Stores information without and.

(processing)
Next, the processing executed by the operating condition identification system for equipment according to the fourth embodiment will be described. Prior to this processing, the above-described information is acquired by any method and stored in advance in the user DB 112a, the equipment DB 112b, and the drawing DB 112c. This process includes a reservation process for making reservations for materials and equipment and an operation rate specifying process for specifying the operation rate of materials and equipment.

(Process-Reservation process)
First, a reservation process for making a reservation for materials and equipment will be described. When the user makes a login request by inputting his or her own user ID and password via the touch pad 101 of the reservation terminal 100, the control unit 104 of the reservation terminal 100 stores the user ID and password in the server. Send to 110. The control unit 111 of the server 110 determines whether or not a combination of these user ID and password is stored in the user DB 112a, and if stored, permits login, generates reservation screen information, and generates a reservation terminal. Send to 100. The control unit 104 of the reservation terminal 100 displays the reservation screen on the display 102 based on the reservation screen information.

FIG. 19 is a diagram showing a display example of a reservation screen. As shown in FIG. 19, the reservation screen is configured to include the item “reservation list”. The item "reservation list" is composed of an item "floor number" and an item "high vehicle name", and is acquired from the equipment DB 112b as information corresponding to the item "floor number" and the item "high vehicle name", respectively. Information of the same item name is displayed. A free entry field is provided below each high car name, and the user can enter arbitrary information (in the example of FIG. 19, “Group A” or the like). In the upper part of the reservation screen, as the information of the logged-in user, the company name (“XX Co., Ltd.” in the example of FIG. 19) and the name (“Yoshida” in the example of FIG. 19) acquired from the user DB 112a. ) Is displayed. In addition, the reservation screen displays information that specifies the month and day (such as "November 14" in the example of FIG. 19), information that specifies the day of the week (such as "month" in the example of FIG. 19), and morning and afternoon. Information to be specified (“AM” in the example of FIG. 19) is displayed.

Further, on the reservation screen, "empty", "completed", and "other" are displayed as information for specifying the reservation status. The information that specifies these reservation statuses is the equipment that is arranged in the number of floors specified by the information that corresponds to the item "floor number", and that is specified by the information that corresponds to the item "high car name". Is the date specified by the information specifying the date, and is the information specifying the status of the reservation in the morning or the afternoon specified by the information specifying the morning and afternoon (hereinafter, these date and morning Or, the afternoon combination is referred to as "reservation time zone"). Of these, "empty" indicates that no reservation has been made, "completed" indicates that a user who is logged in or another user of the same company as the user has made a reservation, and "other" Indicates that a reservation is made by a user of a company other than the company of the logged-in user. For example, “empty” indicated by reference numeral 120 in FIG. 19 indicates that the equipment with the high vehicle name “9m3” located on the floor number “2” is the reserved time of “am” on the month and day “November 15”. The band indicates that no reservation has been made. In addition, for example, “Done” indicated by reference numeral 121 in FIG. 19 indicates that the material/equipment with the high vehicle name “9m3” located on the floor number “2” is reserved for “Afternoon” on the date “November 15” It indicates that the reservation is made by the logged-in user "Yoshida" or another user of the same company "○○ Co., Ltd." as the user "Yoshida" in the time zone. Alternatively, for example, “other” indicated by reference numeral 122 in FIG. 19 indicates that the equipment with the high vehicle name “9m3” located on the floor number “2” is reserved for “am” on the month and day “November 16”. In the time zone, the reservation is made by users of companies other than the same company "○○ Co., Ltd." as the logged-in user "Yoshida". These pieces of information are specified and displayed when the reservation screen is generated by the control unit 111 of the server 110 based on the information corresponding to the item “reservation” in the equipment DB 112b of FIG. 18 and the information input by the user at the time of login. R. For example, if "20171114am-UID0001" is stored as the information corresponding to the item "reservation" and the user ID "UID0001" is acquired as the information input by the user at the time of login, the date "November 14" Since it is possible to specify that the user who has logged in during the reserved time period of "am" of "day" has made a reservation, "completed" is displayed in the corresponding part of the reservation screen. Alternatively, when the user ID included in the information corresponding to the item “reservation” does not match the user ID included in the information input by the user at the time of login, or by referring to the user DB 112a based on each of these user IDs. If the specified company names do not match, "other" is displayed at the corresponding location on the reservation screen. Alternatively, for a reserved time zone that is not included in the information corresponding to the item “reservation” in the equipment/materials DB 112b, “empty” is displayed at the corresponding location on the reservation screen. However, as a structure for storing such reservation information and a method for specifying a reservation time zone, any known structure and method can be adopted. As a result, the user can easily visually confirm the reservation status of each equipment. Note that FIG. 19 shows an example in which the reservation screen is displayed in black and white for convenience of illustration, but the visual effect may be further enhanced by displaying in color. For example, the reservation status is displayed with the characters "empty", "done", and "other", but the frame in which this character is displayed has a different color depending on the reservation status (for example, "empty" is " "White" and "done" may be displayed in "blue", and "other" may be displayed in "gray". In order to distinguish between “dedicated” and “non-dedicated”, the floor and high name of “dedicated” equipment are displayed in “blue”, and the floor and high of “non-dedicated” equipment are shown. The vehicle name may be displayed in "gray".

Then, the user can reserve or cancel the reservation on each of the materials and equipment on the reservation screen. For example, when the user clicks on a frame in which the reservation status is “empty”, the control unit 104 of the reservation terminal 100 corresponds to the material ID of the material corresponding to the clicked frame and the clicked frame. The information indicating the reserved time zone and the user ID acquired at the time of login are transmitted to the server 110. Based on these pieces of information, the control unit 111 of the server 110 stores the reservation information in the relevant part of the item “reservation” in the equipment DB 112b. Further, the control unit 104 of the reservation terminal 100 displays "Complete" instead of "Empty" in the frame of the reservation screen clicked by the user. This completes the reservation. Alternatively, when the user clicks on a frame whose reservation status is “completed”, the control unit 104 of the reservation terminal 100 corresponds to the material ID of the material corresponding to the clicked frame and the clicked frame. The information indicating the reserved time zone and the user ID acquired at the time of login are transmitted to the server 110. The control unit 111 of the server 110 deletes the reservation information stored in the relevant part of the item “reservation” in the equipment DB 112b based on these pieces of information. Further, the control unit 104 of the reservation terminal 100 displays "empty" instead of "completed" in the frame of the reservation screen clicked by the user. This completes the cancellation of the reservation. In this way, since it is possible to easily reserve the materials and equipment, it is possible to increase the utilization rate of the materials and equipment. Alternatively, since it becomes possible to easily cancel the reservation of the material/equipment, it becomes possible for another user to reserve the material/equipment, and the operating rate of the material/equipment can be increased.

Further, the reservation screen is provided with a “MAP” button 123 for confirming the position of the material and equipment, and when the user clicks on the “MAP” button 123, the “MAP” button 123 corresponds to the “MAP” button 123. The location of materials and equipment can be confirmed. The specific method of confirming the position is arbitrary, but for example, when the user clicks the “MAP” button 123, the equipment ID of the equipment corresponding to the “MAP” button 123 is transferred from the reservation terminal 100 to the server 110. Then, the control unit 111 of the server 110 converts this equipment ID using the equipment information beacon ID of the first embodiment using conversion information prepared in advance (for example, equipment ID “EID0001” Beacon ID “E0001” is converted), and the converted equipment beacon ID is transmitted to the server 50 of the first embodiment. The control unit 51 of the server 50 acquires the application display log corresponding to the equipment beacon ID and transmits it to the server 110. The control unit 111 of the server 110 identifies the position of the material/equipment based on the application display log, and superimposes and displays a predetermined thumbnail indicating the material/equipment on the corresponding position on the drawing stored in the drawing DB 112c. Drawing information is generated and this drawing information is transmitted to the reservation terminal 100. The control unit 104 of the reservation terminal 100 displays the drawing on the display 102 based on this drawing information. As a result, the user can easily visually confirm the position of each equipment.

Further, the reservation screen is provided with a “return” button 124 for requesting the return of the materials and equipment, and when the user clicks the “return” button 124, the “return” button 124 is responded to. You can request the return of materials and equipment. For example, when the user clicks the “return” button 124 corresponding to the material/material to be returned, the control unit 104 of the reservation terminal 100 causes the server 110 to input the material/material ID of the material/material corresponding to the clicked “return” button 124. Send. The control unit 111 of the server 110 refers to the material/material DB 112b based on the material/material ID, and changes the information of the item “dedicated” corresponding to the material/material ID to “non-dedicated”. In addition, the control unit 111 of the server 110 is a mail in a predetermined format for requesting a return to the equipment manager based on the email address of the equipment administrator set in advance, and the return is requested. Send an email containing the equipment ID of the equipment. As a result, the equipment manager can request the equipment and materials manager to return the unnecessary equipment and materials to the rental company, so that the equipment and materials manager can return the unnecessary equipment and materials in a timely manner, and rent the equipment and materials. The cost can be reduced.

Further, the reservation screen is provided with a “position confirmation” button 125 for confirming the position of the equipment and materials, and the user clicks the “position confirmation” button 125 to confirm the position of the equipment and materials. be able to. Although a specific method of confirming the position is arbitrary, for example, when the user clicks the “confirm position” button 125, a position confirmation request is transmitted from the reservation terminal 100 to the server 110, and the control unit 111 of the server 110 This position confirmation request is transmitted to server 50 of the first embodiment. The control unit 111 of the server 110 acquires an application display log corresponding to each equipment beacon ID and transmits it to the server 110. The control unit 111 of the server 110 identifies the position of the material/equipment based on the application display log, and superimposes and displays a predetermined thumbnail indicating the material/equipment on the corresponding position on the drawing stored in the drawing DB 112c. Drawing information is generated and this drawing information is transmitted to the reservation terminal 100. The control unit 104 of the reservation terminal 100 displays the drawing on the display 102 based on this drawing information. As a result, the user can easily visually confirm the position of each equipment. At this time, for example, a drawing of a specific floor is displayed, icons are displayed at the respective positions of all the equipment arranged on the floor, and corresponding information (high car name, reservation, etc.) is displayed. If there is, the user name or company name of the user who has made the reservation is displayed. Further, on this screen, a pull-down menu for switching the floor number is displayed, and when the floor number for which the drawing is desired to be viewed is selected via this pull-down menu, it is possible to switch to the display of the drawing of the selected floor number. As a result, the user can easily visually confirm the position of each material and equipment and make a reservation or the like with reference to this position.

Further, on the reservation screen, there is provided a “search for an empty vehicle” button 126 for searching for available materials and equipment. When the user clicks on the “search for an empty vehicle” button 126, the available resources are searched. You can search for equipment. For example, when the user clicks the “search for an empty car” button 126, a search request is transmitted from the reservation terminal 100 to the server 110, and the control unit 111 of the server 110 generates search screen information and transmits it to the reservation terminal 100. The control unit 104 of the reservation terminal 100 displays the search screen on the display 102 based on the search screen information.

FIG. 20 is a diagram showing a display example of the search screen. As shown in FIG. 20, the search screen is configured in substantially the same manner as the reservation screen, but in the upper part, a frame 130 for displaying the floor number of the material and equipment to be searched and the floor number of the material and material to be searched are selected. A drop-down list 131, a frame 132 for displaying the type of material/equipment to be searched, a drop-down list 133 for selecting the type of material/equipment to be searched, and a “search” button 134 for instructing a search are provided. Then, when the user selects these floors and types and clicks the “search” button 134, these floors and types are transmitted to the control unit 111 of the server 110. The control unit 111 of the server 110 refers to the material/material DB 112b based on the number of floors and types, and identifies the material/equipment that matches the number of floors and types and has "empty" in the reservation status. Then, the search screen information is generated based on only the information about the specified equipment and transmitted to the reservation terminal 100. As a result, the user can visually and easily confirm the materials and equipment that match his or her desired conditions, and make a reservation or the like with reference to this position. The search screen is provided with a “position confirmation” button 135 having the same function as the “position confirmation” button 125 of FIG. 19 and a “reserve” button 136. The user can click the button 136 to return to the reservation screen of FIG.

(Processing-operation rate specifying process)
Next, an operation rate specifying process for specifying the operation rate of the equipment will be described. When the user logs in at the reservation terminal 100 similarly to the reservation process and then requests the operation rate identification by an arbitrary method, the control unit 104 of the reservation terminal 100 transmits an operation rate identification request to the server 110. The control unit 111 of the server 110 refers to the server DB, calculates the operating rate of each equipment, and transmits the calculated operating rate to the reservation terminal 100. The control unit 104 of the reservation terminal 100 displays the operating rate on the display 102.

As this operating rate, for example, two types of operating rates can be calculated and displayed. One of the operation rates is the dedicated period utilization rate, which is calculated by using the dedicated period utilization rate=the utilization rate of materials/equipment/the exclusive utilization rate of materials/equipment. Here, the usage rate of the materials and equipment is a time ratio in which the materials and equipment are used for a predetermined period (for example, a period specified by the user when requesting the operation rate to be specified, for one week or one month). , Utilization rate of materials/equipment = time during which materials/equipment was used / predetermined period The time when the materials and equipment have been used can be acquired from the server 50 of the first embodiment, for example. The exclusive rate of materials and equipment is the time ratio in which the materials and equipment are “exclusive” during a predetermined period (for example, a period specified by the user when requesting the operation rate, for one week or one month). , Utilization rate of material/equipment = time when material/equipment was “exclusive”/predetermined period. By grasping the usage rate for such a dedicated period, it becomes possible to easily and accurately ascertain how much the equipment was used during the "dedicated" period. By returning low-priced equipment to the rental company, it becomes possible to reduce rental costs for equipment.

The other operation rate is the exclusive rate (empty input exclusive rate), which is calculated by exclusive rate = reservation exclusive period/total exclusive period. Here, the reservation-dedicated period is a period in which the equipment is “dedicated” and reserved. The all-dedicated period is the period during which the equipment was "dedicated". By grasping such exclusive rates, it is possible to easily and accurately grasp how much the equipment was reserved during the period of "exclusive", and for equipment with low exclusive rates. By returning to the rental company, it will be possible to reduce the rental cost of materials and equipment.

[III] Modifications to Embodiments Although the embodiments according to the present invention have been described above, the specific configurations and means of the present invention are within the scope of the technical idea of each invention described in the claims.

May be specified.

(About receiving terminal)
In the present embodiment, the case where all the workers have the receiving terminal 10 has been described, but the present invention is not limited to this, and only the on-site manager may have the receiving terminal 10, or a part of the workers. May carry a beacon instead of the receiving terminal 10 and specify the position in the same manner as the equipment.

(About equipment beacon)
If there is a material/material beacon 30 that has not received a radio wave for a predetermined time or longer (for example, for a day or longer), a worker may be prompted to confirm the material/material. For example, referring to the item “time” of the equipment position log table 52c, if the latest log is before the current time by a predetermined time (for example, one day), the equipment beacon of the equipment beacon 30 concerned. The ID-added signal may be transmitted to the receiving terminal 10, and the receiving terminal 10 receiving this signal may highlight the equipment icon I2 of the equipment (for example, display it in a different color from other beacons). ..

(Regarding specific aspects of equipment)
In each embodiment, the method of identifying the operating status of the aerial work vehicle as the material and equipment has been described, but the operating status of other types of material and equipment can be specified in the same specific manner. Further, the operating status may be specified in different specification modes depending on the type of materials and equipment. For example, when identifying the operating status of an elevator, the equipment beacon 30 is attached to the elevator, and the radio waves from the equipment beacon 30 are transmitted to the receiving terminals existing on multiple floors within a predetermined time (for example, 10 minutes). When the radio wave is received by the elevator, it may be determined that the elevator is moving across the floor and is operating. According to such a modified example, since the operating status of the equipment is specified in different identification modes according to the type of the materials and equipment, the operation status can be identified in the optimal manner according to the type of the materials and equipment. Accuracy and speed are improved.

For example, a vibration sensor may be used to identify the operating status of the equipment from the vibration status of the equipment. When the equipment is started up or used, some vibration occurs. Therefore, when the vibration is detected, if the electric wave is transmitted from the vibration sensor including the operation flag ON information, the equipment operates like the second and third embodiments. The situation can be specified.

(About calculation and output of operating status)
The operation status identifying system for the materials and equipment described in the fourth embodiment is described as a system different from the operation status specifying system for the materials and equipment in the first to third embodiments, but both of them or Some may be integrated. For example, the server 50 of FIG. 2 and the server 110 of FIG. 16 may be integrated, or the receiving terminal 10 of FIG. 2 and the reservation terminal 100 of FIG. 16 may be integrated. In these cases, it is possible to store the information that correlates the equipment IDs described in the first to third embodiments with the equipment IDs described in the fourth embodiment, and thus the first to third embodiments. Associating the operating rate of each material and equipment calculated in step (hereinafter, transmitter operating rate) and the operating rate of each material and material (hereinafter, reserved operating rate) calculated in Embodiment 4 with the same material and equipment You can Then, for example, by calculating the ratio of the transmitter operating rate to the reserved operating rate, the ratio (actual operating rate) at which the equipment is reserved and is actually operating, or the actual operating rate is calculated from 100%. By subtracting, it is possible to obtain the ratio (vacant reservation rate) that the equipment is not actually operating even though it is reserved, and compensate for the low accuracy of the transmitter operation rate. It is possible to evaluate the operating rate from various perspectives.
