The work equipment 100 is, for example, equipment procured by rental at the construction site of the multi-layer structure 2.
The power supply unit 110 is, for example, a power supply battery for an aerial work platform. The power supply unit 110 supplies electric power to the corresponding drive unit (not shown) of the work equipment 100 when various operations are performed on the work equipment 100. Alternatively, the power supply unit 110 may be a power supply cable or the like that is connected to a commercial power supply or the like and supplies power to the work equipment 100.

Here, the control unit 32 is an example of the “first acquisition unit”. Further, the communication unit 33 is an example of the "first communication unit".

The operation sensor 30 is, for example, a clamp-type current sensor having a clamp 300. The operation sensor 30 detects the current value flowing through the work device 100 by sandwiching the positive (+) terminal of the power supply unit 110 of the work device 100 with the clamp 300. The operation sensor 30 outputs the detected current value to the control unit 32.
The barometric pressure sensor 31 is, for example, a barometer that detects atmospheric pressure. The atmospheric pressure sensor 31 is built in the operation information communication module 3, for example, and detects the atmospheric pressure at the place where the work equipment 100 to which the operation information communication module 3 is attached is arranged. The barometric pressure sensor 31 outputs information indicating the detected atmospheric pressure to the control unit 32.

The communication unit 33 communicates with another operation information communication module 3, the reference floor relay module 4, and the management device 5, which are different from the own device. The communication unit 33 transmits information to the management device 5, for example, based on the control of the control unit 32. Further, the communication unit 33 relays the information transmitted from the other operation information communication module 3 and the reference floor relay module 4 to the management device 5. For example, when the transmission destination of the received information is the management device 5, the communication unit 33 transmits the information to the management device 5.
The power supply unit 34 supplies electric power to each component of the operation information communication module 3. FIG. 2 shows an example in which the power supply unit 34 receives power from the power supply unit 110 included in the work equipment 100. However, the present invention is not limited to this, and for example, the power supply unit 34 may be a storage battery built in the operation information communication module 3, a power supply cable for supplying power to the operation information communication module 3, or the like. There may be.

The control unit 32 determines, for example, whether or not the work equipment 100 is operating based on the current value detected by the operation sensor 30. For example, the control unit 32 determines that the work equipment 100 is operating when the current value detected by the operation sensor 30 is equal to or higher than a predetermined threshold value. Further, when the current value detected by the operation sensor 30 is less than a predetermined threshold value, the control unit 32 determines that the work equipment 100 is not operating.
The control unit 32 determines, for example, whether the work equipment 100 is operating at a predetermined time (hereinafter, referred to as management time) at a predetermined interval (for example, 10 to 60 minutes) (hereinafter, referred to as management time). , Acquire the judgment result as operation information. Then, the control unit 32 acquires the atmospheric pressure detected by the barometric pressure sensor 31 at the control time as pressure information.
The control unit 32 associates the operation information with the atmospheric pressure information and transmits the operation information to the management device 5 via the communication unit 33.

For example, the control unit 32 writes operation information or the like to the operation information management table (see FIG. 3A) stored in the storage unit (not shown) of the operation information communication module 3 to the management device 5. Generates information to be transmitted (hereinafter referred to as transmission information).
FIG. 3A is a diagram showing an example of an operation information management table. In the example of FIG. 3A, the operation information management table has items of management time T, operation information W, and transmission determination D, respectively. The management time T is a predetermined time for each management time (for example, 60 minutes), the operation information W is the operation information at each management time, and the transmission determination D is whether or not the information at each management time is successfully transmitted. Each is memorized. In the example of FIG. 3A, the case where the management time is set to 60 minutes is shown.

Hereinafter, a method in which the control unit 32 generates transmission information corresponding to the management time T (for example, T = 13) will be described as an example.
First, the control unit 32 starts monitoring the current value detected by the operation sensor 30 at the management time T (= 13).
Next, when the monitored current value exceeds a predetermined threshold value, the control unit 32 stores "1" in the operation information W column corresponding to the management time T (= 13). After that, the control unit 32 suspends the monitoring of the current value until the next management time T (= 14). As a result, the increase in power consumption in the operation information communication module 3 is suppressed.
Then, when the next management time T (= 14) is reached, the control unit 32 acquires the atmospheric pressure detected by the atmospheric pressure sensor 31 at that time as atmospheric pressure information. Then, the control unit 32 associates the operation information W (= 1) at the immediately preceding management time T (= 13), the management time T (= 13), and the atmospheric pressure information with the identification information of the operation information communication module 3. By doing so, transmission information is generated.
The control unit 32 continues monitoring the current value started at the management time T (= 13) until the next management time T (= 14), and the current value monitored during that time is predetermined. If it is less than the threshold value, "0" is stored in the operation information column corresponding to the management time T (= 13). Then, the control unit 32 associates the operation information W (= 0) at the immediately preceding management time T (= 13), the management time T (= 13), and the atmospheric pressure information with the identification information of the operation information communication module 3. By doing so, transmission information is generated.

Further, when the transmission information is successfully transmitted (for example, when a transmission error is not shown in the response corresponding to the transmission), the control unit 32 is in the transmission determination D column corresponding to the management time T (= 13). To memorize "1".
When the transmission of the transmission information fails (for example, when a transmission error is indicated in the response corresponding to the transmission), the control unit 32 transmits the transmission information to the management device 5 again. When the transmission of the transmission information fails a predetermined number of times (for example, three times), the control unit 32 stores "0" in the transmission determination D column corresponding to the management time T (= 13).
Then, when the next management time T (= 15) is reached, the control unit 32 refers to the column of the transmission determination D corresponding to the management time T (≦ 13) before the immediately preceding management time T (= 14). When "0" is stored in the transmission determination column, the transmission information at the management time T and the transmission information at the immediately preceding management time T (= 14) are transmitted to the management device 5, respectively.

The reference floor relay module 4 includes a barometric pressure sensor 40, a control unit 41, a communication unit 42, and a power supply unit 43. Here, the control unit 41 is an example of the “second acquisition unit”. Further, the communication unit 42 is an example of the “second communication unit”.

The barometric pressure sensor 40 is built in the reference floor relay module 4, for example, and detects the pressure of the atmosphere at the place where the reference floor relay module 4 is arranged. The barometric pressure sensor 40 outputs information indicating the detected atmospheric pressure to the control unit 41.
The communication unit 42 communicates with the operation information communication module 3, another reference floor relay module 4 different from the own device, and the management device 5. The communication unit 42 transmits information to the management device 5, for example, based on the control of the control unit 41. Further, the communication unit 42 relays the information transmitted from the other operation information communication module 3 and the reference floor relay module 4 to the management device 5. For example, when the transmission destination of the received information is the management device 5 instead of itself, the communication unit 42 transmits the information to the management device 5.
The power supply unit 43 is, for example, a storage battery built in the reference floor relay module 4. Alternatively, the power supply unit 43 may be a power supply cable or the like that supplies power to the reference floor relay module 4.

For example, at the control time, the control unit 41 acquires the atmospheric pressure detected by the barometric pressure sensor 40 at the control time as the reference floor pressure information. The control unit 41 transmits the acquired reference floor pressure information and the management time to the management device 5 via the communication unit 33 with the information (hereinafter referred to as the reference floor transmission information) associated with the identification information of the reference floor relay module 4.

In the example of FIG. 4A, the operation status table for each work device has items of work device, date, management time T, operation information W, work floor F, and reception determination R. The work equipment is the management number of the work equipment 100, the date is the date when the operation information or the like is acquired, the management time T is the predetermined time for each management time, and the operation information W is the operation information at each management time and the work floor. The work floor on which the target work equipment 100 is arranged is stored in F, and whether or not the reception of the operation information or the like at each management time is successful is stored in the reception determination R.
As shown in FIG. 4A, in the operation status table for each work device, the operation information and the work floor are aggregated for each day and for each work device 100.

FIG. 4B is a diagram showing an example of an operation status table for each work floor. In the example of FIG. 4B, the operation status table for each work floor has items of floor, ID, number of units, and operation rate. The number of floors of each floor in the structure 2 is stored in the floor.

The number of units includes items that are in use and unused, and the number of work equipment 100 arranged on each floor is stored in each item according to the operating status. The ratio [%] of the number of working equipment 100 to the number of working equipment 100 working on each floor is stored in the operating rate.

The output unit 53 is, for example, a display, and displays the floor pressure table, the work equipment operation status table, or the work floor operation status table stored in the storage unit 52 on the display.

The control unit 51 is realized by, for example, a processor such as a CPU executing a program stored in the program memory, and controls the management device 5 in an integrated manner. Based on the information received by the communication unit 50, the control unit 51 determines the work floor indicating where the work equipment 100 to which the operation information communication module 3 is attached is located.
First, the control unit 51 determines the reference floor in which the reference floor relay module 4 that has transmitted the information is arranged, based on the reference floor transmission information received by the communication unit 50. In the control unit 51, for example, a reference floor relay module 4 corresponding to a predetermined identification information and the identification information is arranged based on the identification information included in the reference floor transmission information transmitted by the reference floor relay module 4. By referring to a table (not shown) in which the relationship between the reference floors is stored, the reference floor in which the reference floor relay module 4 is arranged is determined.

Next, the control unit 51 acquires the atmospheric pressure at the reference floor based on the reference floor transmission information for which the reference floor has been determined. The control unit 51 writes and stores the acquired atmospheric pressure of the reference floor in the corresponding column of the atmospheric pressure table for each floor. For example, the control unit 51 sets the atmospheric pressure indicated by the reference floor pressure information included in the reference floor transmission information for determining the reference floor as the determined reference floor pressure. In the example of FIG. 3B, the reference floor pressures of the reference floors (1F, 5F, and 10F) are (1012.0 [hPa], 1010.0 [hPa], and 1007.8 [hPa], respectively. Indicates the case where.

Next, the control unit 51 derives the air pressure of each floor based on the air pressure of each reference floor.
There are two methods for the control unit 51 to derive the atmospheric pressure of each floor. Each method will be referred to as a first method and a second method for deriving the atmospheric pressure of each floor, and will be described below in order.
As a first method of deriving the atmospheric pressure of each floor, the control unit 51 divides the difference of the atmospheric pressure of each of the two reference floors by the difference of the height of the two reference floors, for example. Derivation of the air pressure of the floor located in between. In the example of FIG. 3B, the control unit 51 sets the difference in atmospheric pressure (= 1010-1007.8 [hPa]) between the two reference floors (for example, 10F and 5F) as the difference in height (=). The value divided by 39-19 [m]) is calculated as the amount of change in atmospheric pressure [hPa / m] per unit height. Then, the control unit 51 multiplies the calculated atmospheric pressure change amount [hPa / m] by the height difference (= 39-35 [m]) between the reference floor (for example, 10F) and each floor (for example, 9F). By subtracting the obtained value to the atmospheric pressure (1007.8 [hPa]) of the reference floor (10F), the atmospheric pressure (= 1008.2 [hPa]) of each floor (9F) is derived.
As a second method of deriving the atmospheric pressure of each floor, the control unit can, for example, control the atmospheric pressure of a certain reference floor, a predetermined amount of change in atmospheric pressure (for example, -0.112 [hPa / m]), and the reference floor thereof. And the atmospheric pressure of each floor is derived based on the difference in height of each floor. In the example of FIG. 3B, the control unit 51 changes the atmospheric pressure (1012.0 [hPa] of a certain reference floor (for example, 1F) to a predetermined predetermined atmospheric pressure change amount (for example, −0.112 [hPa]). / M]) multiplied by the difference in height (0- (-4) [m]) between the reference floor (1F) and each floor (for example, B1F), and the atmospheric pressure of each floor (B1F) is subtracted. (1012.4 [hPa] is derived.

For example, the control unit 51 sets the atmospheric pressure of the floor located between the two reference floors (for example, the floor between the 1st floor and the 10th floor in FIG. 3B, excluding the reference floor) in the first method. The atmospheric pressure of the floor not located between the two reference floors (for example, B1F and B2F in FIG. 3B) is derived by the second method. However, the present invention is not limited to this, and the control unit 51 may derive all the floors in the structure 2 except the reference floor by the first method, or all the floors in the structure 2 except the reference floor. The floor may be derived by the second method. The control unit 51 stores the derived atmospheric pressure in the corresponding portion of the item of atmospheric pressure for each floor of the atmospheric pressure information table.
By the control unit 51 deriving the atmospheric pressure of each floor based on the atmospheric pressure of the reference floor, even if the atmospheric pressure of the atmosphere changes with time, it is possible to more accurately determine where the working floor is. Can be done. The control unit 51 updates the atmospheric pressure of the corresponding reference floor every time it receives information from the reference floor relay module 4, and derives the atmospheric pressure of each floor based on the updated atmospheric pressure of the reference floor. Alternatively, the air pressure on each floor may be derived at the timing when the information is completely received from all the reference floor relay modules 4 arranged in the structure 2 (for example, 5 minutes after the management time). ..

Further, the control unit 51 determines where the work floor of the work equipment 100 to which the operation information communication module 3 is attached is based on the derived atmospheric pressure on each floor. For example, the control unit 51 determines where the work floor of the work equipment 100 to which the operation information communication module 3 is attached is by comparing the derived atmospheric pressure of each floor with the atmospheric pressure shown in the atmospheric pressure information. In the example of FIG. 3B, when the atmospheric pressure indicated by the atmospheric pressure information included in the transmission information is 1010.8 [hPa], the control unit 51 refers to the atmospheric pressure table for each floor and the difference from the atmospheric pressure in each floor. Determines on the smallest floor (3F) where the work floor of the work equipment 100 to which the operation information communication module 3 that transmitted the transmission information is attached is.

The control unit 51 associates the determined work floor with the identification information together with the operation information, and writes and stores the determined work floor in the operation status table for each work device shown in the example of FIG. 4A. Further, the control unit 51 generates an operation status table for each work floor shown in the example of FIG. 4B based on the operation status table for each work equipment.
For example, the control unit 51 refers to the operation status table for each work device at a predetermined timing, and for each work floor, the number of work devices 100 in use among the work devices 100 arranged on that floor, The number of unused work devices 100 is totaled. The timing at which the control unit 51 refers to the operation status table for each work device is, for example, a predetermined time from the management time (for example, 10) on which it is assumed that the control unit 51 finishes receiving the transmission information corresponding to the management time and the reference floor transmission information. Minutes) have passed. The number of work devices 100 in use is the number of work devices 100 in which "1" is stored in the operation information in the operation status table for each work device. Further, the unused work equipment 100 is the number of work equipment 100 in which "0" is stored in the operation information in the operation status table for each work equipment.

Here, an operation example of the operation management system 1 of the embodiment will be described with reference to FIG.
FIG. 5 is a flowchart showing an operation example of the management device 5 of the embodiment.
First, the management device 5 receives the transmission information transmitted by the operation information communication module 3 and acquires the operation information and the atmospheric pressure information included in the transmission information (step S1).
Next, the management device 5 receives the information transmitted by the reference floor relay module 4 and acquires the reference floor pressure information included in the information (step S2).
Next, the management device 5 determines where the work floor of the work equipment 100 that has transmitted the transmission information is, based on the atmospheric pressure indicated in the atmospheric pressure information and the reference floor pressure indicated in the reference floor pressure information ( Step S3).
Then, the management device 5 stores the determined work floor and the operation information in the operation status management table in association with each other (step S4).

As described above, the operation management system 1 of the embodiment is an operation management system including an operation information communication module 3, a reference floor relay module 4, and a management device 5 capable of communicating with each other. The operation information communication module 3 has a control unit 32 that acquires atmospheric pressure information indicating the atmospheric pressure at a place where the work by the work equipment 100 is performed, and a communication unit 33 that transmits the atmospheric pressure information to the management device 5. The reference floor relay module 4 has a control unit 41 that acquires reference floor pressure information indicating the atmospheric pressure in the reference floor, and a communication unit 42 that transmits the reference floor pressure information to the management device 5. The management device 5 has a communication unit 50 that receives atmospheric pressure information and reference floor pressure information, and a control unit 51 that determines where the work floor of the work equipment 100 is based on the atmospheric pressure information and the reference floor pressure information.
As a result, the operation management system 1 of the embodiment has the above-mentioned effect. This is because the management device 5 can derive the atmospheric pressure of each floor based on the reference floor atmospheric pressure information, and can determine where the working floor of the work equipment 100 is based on the derived atmospheric pressure and atmospheric pressure information of each floor.

Here, as a comparative example, consider a configuration in which the management device 5 determines where the work floor of the work equipment 100 is based only on the atmospheric pressure information transmitted from the operation information communication module 3. In this case, the management device 5 may determine where the work floor of the work equipment 100 is, for example, assuming that the atmospheric pressure on the 1st floor is 1 atm. However, since the place where the structure 2 is constructed may be a place where the altitude is high or a place where the altitude is low, the pressure on the 1st floor is not always 1 atm, and it is accurate where the work floor is. Cannot be determined. Further, even if it is possible to determine where the work floor is, the atmospheric pressure changes with time, so if the atmospheric pressure fluctuates depending on the atmospheric condition, it is possible to accurately determine where the work floor of the work equipment 100 is. It will disappear.
On the other hand, in the operation management system 1 of the embodiment, the management device 5 derives the atmospheric pressure of the reference floor and the atmospheric pressure of each floor based on the reference floor pressure. Thereby, even when the structure 2 is constructed in a place where the altitude is high or a place where the altitude is low, it is possible to accurately determine where the work floor of the work equipment 100 is. Further, even if the atmospheric pressure changes with time, the atmospheric pressure of each floor can be derived based on the atmospheric pressure of the reference floor after the change, so it is possible to accurately determine where the working floor of the work equipment 100 is. can do.

Further, in the operation management system 1 of the embodiment, the reference floor pressure information acquired by the control unit 41 includes the reference floor pressure information in at least two reference floors, and the control unit 51 includes the reference floor pressure information of each floor in the structure 2. Based on the height, the atmospheric pressure of the floor located between the two reference floors is derived by apportioning the difference between the atmospheric pressures of the two reference floors shown in each of the two reference floor pressure information, and the derived atmospheric pressure of each floor is derived. The working floor is determined by comparing with the atmospheric pressure shown in the atmospheric pressure information.
As a result, the operation management system 1 of the embodiment has the above-mentioned effect. This is because the management device 5 can derive the atmospheric pressure of each floor based on the reference floor atmospheric pressure information, and can determine where the working floor of the work equipment 100 is based on the derived atmospheric pressure and atmospheric pressure information of each floor.

Further, in the operation management system 1 of the embodiment, the control unit 32 acquires the operation information indicating whether or not the work equipment 100 is operating, and the communication unit 33 associates the operation information with the atmospheric pressure information and manages the management device 5. The communication unit 50 receives the operation information, and the control unit 51 generates an operation status table for each work floor in which the operation information is associated with the work floor.
As a result, the operation management system 1 of the embodiment can obtain the above-mentioned effects and can determine the operation status of the work equipment 100. The management device 5 determines where the work floor of the work equipment 100 is, and further acquires the operation information of the work equipment 100, so that the work equipment 100 is located on which floor in the structure 2 and how many of them. This is because it is possible to count whether the machines are in operation. That is, as compared with the conventional case, the work equipment 100 can be rented in the optimum number without becoming excessive, which leads to cost reduction.
Conventionally, when the work equipment 100 is insufficient at the work site, even if there is a work equipment 100 that is not in operation at another work site of the structure 2, the information is not shared and the work equipment that is not in operation is not shared. It was conceivable that the work equipment 100 could not be found and the work equipment 100 was additionally rented even though there was a work equipment 100 that was searched around for 100 or was not in operation.
On the other hand, in the operation management system 1 of the embodiment, the management device 5 generates an operation status table for each work floor, so that the current work floor and the operation status of the work equipment 100 can be disclosed to the workers. It is possible to grasp where the non-operating work equipment 100 is without having to search around for the non-operating work equipment 100. In addition, by disclosing the current work floor and operating status of the work equipment 100 to the workers, it is possible to suppress a situation in which the work equipment 100 is additionally rented even though there is a work equipment 100 that is not in operation. be able to.

Further, in the operation management system 1 of the embodiment, the control unit 32 determines whether or not the work equipment 100 is operating based on the operating current value flowing through the work equipment 100 when the work equipment 100 is in operation, and determines whether or not the work equipment 100 is operating. The operation information is acquired based on the judgment result.
As a result, in the operation management system 1 of the embodiment, in addition to achieving the above-mentioned effects, the control unit 32 acquires the operating current value of the work device 100, and the work device 100 easily operates based on the acquired current value. Can be determined.
Further, in the operation management system 1 of the embodiment, there are a plurality of operation information communication modules 3, and a tree-type network in which the plurality of operation information communication modules 3, the reference floor relay module 4, and the management device 5 are wirelessly connected is formed. Form.
As a result, in the operation management system 1 of the embodiment, in addition to the above-mentioned effects, the network between the operation information communication module 3, the reference floor relay module 4, and the management device 5 is more firmly established. Since the information transmitted by the operation information communication module 3 and the reference floor relay module 4 is reliably received by the management device 5, it is possible to accurately determine where the work floor of the work equipment 100 is.

In the above-described embodiment, an example in which the management device 5 generates an operation status table for each work floor for each management time has been described, but the management device 5 has a working time of one day (for example, from 8:00 am to pm). The operation status table for each work floor corresponding to the management time included in (until 5 o'clock) may be aggregated to generate the operation status table for each work floor for each day. As a result, if there is a bias in the work floor of the work equipment 100 on that day, the bias can be clarified, and the movement plan for leveling the bias and the number of rental equipment returned can be clarified. , Rental cost and placement space can be reduced.
Further, the management device 5 may aggregate the work floors of the work devices 100 at the end of the day (for example, 5 pm). Further, the control unit 51 may generate a weekly or monthly work floor operation status table based on the daily work floor operation status table. As a result, it is possible to formulate a work plan considering the next week's process from the weekly work floor and operation status. For example, efficient work such as moving the work equipment 100 to the next week's work floor in advance can be performed. Can be promoted. In addition, it is possible to formulate a work plan considering the next month's process from the monthly work floor and operating status, and when renting equipment on a monthly basis, it is possible to adjust the excess or deficiency of the number of rental units on a monthly basis.
Further, the management device 5 may detect and output a malfunctioning work device 100 that is not in operation based on the daily, weekly, and monthly work floors and operating conditions. As a result, if there is a malfunctioning work equipment 100, it can be expected that the rental company will be notified promptly so that the work equipment 100 can be replaced or repaired promptly, and the work equipment 100 can be operated efficiently. Can be made to.
