Specific embodiments of the present invention are described below with reference to the drawings.

Figure 1 shows a system configuration diagram of a workload management system 100 including a server according to one embodiment of the present invention. For example, the workload management system 100 used by a transportation company is a system for managing the workload of workers within the premises of a facility (factory, warehouse, etc.) where work vehicles such as forklifts run.

The workload management system 100 includes a server 20, a beacon 40, and an in-vehicle device 50. In addition, a PC (personal computer) 10 that is placed in the office of the transportation company and operated by an administrator, and a mobile terminal 30 that is operated by the administrator in the same manner as the PC 10, can be connected to the workload management system 100.

The server 20 is connected to a network N such as the Internet, and can communicate with the PC 10, the mobile terminal 30, and the vehicle-mounted device 50 via the network N. In particular, the server 20 functions as a work amount calculation device that calculates the amount of work done by a worker based on data acquired from the vehicle-mounted device 50. In particular, the server 20 in this embodiment functions as a device that counts the number of times the vehicle-mounted device 50 travels between two points within a specified period of time, as described below.

Beacons 40 are generally installed in multiple locations in a facility and are transmitters that emit radio waves including an ID, i.e., a beacon ID, which is identification information for identifying the beacon itself. In the illustrated example, a first beacon (first transmitter) 40A and a second beacon (second transmitter) 40B are shown.

The vehicle-mounted device 50 is mounted on a work vehicle 60 traveling within the facility premises, receives information about the work vehicle 60, performs predetermined processing, and transmits the predetermined information. In particular, the vehicle-mounted device 50 can receive radio waves from the beacon 40 and extract the beacon ID. The beacon ID corresponds to the position of each beacon and is information that indicates the position of the vehicle-mounted device 50 within the premises. The vehicle-mounted device 50 records operation data that includes the beacon ID itself and the time when the beacon ID was received.

The PC 10 is placed in the office of the transportation company, and users including managers and operators can check data such as workload by receiving various information from the server 20 via the network N. The mobile terminal 30 is a portable electronic device such as a smartphone or tablet, and receives various information from the server 20 in the same way as the PC 10.

The beacon 40 and the vehicle-mounted device 50 can wirelessly communicate with each other using short-range wireless communication such as Bluetooth. The beacon 40 and the vehicle-mounted device 50 can also be wirelessly connected to the network N via the base station B using a wireless LAN. The mobile terminal 30 can also be wirelessly connected to the network N via the base station B using a mobile phone network such as LTE (Long Term Evolution) or 5G.

Reducing the burden on workers at facilities and improving work efficiency have long been issues. Work that deserves particular attention is work in which a work vehicle 60 travels between two specific locations, alternating between loading and unloading cargo. Because such work occurs frequently within facilities, by counting the number of trips made by the worker of the work vehicle 60, it is possible to ascertain the amount of cargo being transported. Furthermore, the count can also be used to help evaluate the efficiency of the worker's work.

Therefore, the server 20 of this embodiment acquires the operation data recorded by the vehicle-mounted device 50 at the facility, grasps the number of round trips made by the work vehicle between two points, and analyzes the data to make effective use of it.

FIG. 2 is a block diagram of a server 20 according to an embodiment. The server 20 includes a control unit 21, a receiving unit 22 (data acquisition unit), a transmitting unit 23, an analyzing unit 24, a memory unit 25, an input unit 26, and an output unit 27.

The control unit 21 is the part that is responsible for the overall control of the server 20, and is composed of various arithmetic processing devices (computers). The receiving unit 22 receives various data from the PC 10, the mobile terminal 30, and the vehicle-mounted device 50 via the network N. In particular, the receiving unit 22 functions as a data acquisition unit that receives the above-mentioned operation data from the vehicle-mounted device 50, but may also receive other data. The transmitting unit 23 transmits various data to the PC 10, the mobile terminal 30, and the vehicle-mounted device 50 via the network N. In particular, the transmitting unit 23 can transmit the analysis results of the analysis unit 24, which will be described later, to the PC 10 and the mobile terminal 30.

The analysis unit 24 analyzes the operation data acquired by the receiving unit 22. A specific analysis method will be described later. The storage unit 25 stores the operation data acquired by the receiving unit 22. The storage unit 25 may store various programs that are read by the control unit 21 to cause the server 20 to execute various functions.

The input unit 26 is an input device such as a keyboard or a mouse, and is a device that accepts data that the user directly inputs to the server 20. The output unit 27 includes a device that outputs video, such as a liquid crystal display device, and a device that outputs audio.

Figure 3 is a block diagram of the vehicle-mounted device 50. The vehicle-mounted device 50 includes a receiver 51, a transmitter 52, and a memory 53. The receiver 51 receives radio waves from the beacon 40 and extracts the beacon ID. The memory 53 records operation data that links the beacon ID received by the receiver 51 with the reception time when the beacon ID was received. The transmitter 52 transmits the operation data recorded by the memory 53 to the server 20 via the network N.

Figure 4 is a block diagram of the beacon 40. The beacon 40 includes a receiver 41 and a transmitter 42. The receiver 41 receives information, for example, from the server 20 via the network N, that the beacon 40 is located at one of two points between which the work vehicle 60 makes a round trip. That is, the server 20 can specify two beacons corresponding to two points on the round trip route, thereby specifying the round trip route between which the number of round trips by the work vehicle 60 should be counted, for example, the route between the first beacon 40A and the second beacon 40B.

The transmitter 42 constantly transmits radio waves including a beacon ID, which is identification information for identifying the beacon. The vehicle-mounted device 50 records the beacon IDs received from the beacon 40 in chronological order. When the distance between the vehicle-mounted device 50 and the beacon 40 is within a certain distance, the vehicle-mounted device 50 can receive radio waves and record operational data including the beacon ID.

Figure 5 is a table showing an example of operation data recorded in the memory unit 53 of the vehicle-mounted device 50. The operation data includes at least the beacon ID contained in the radio waves received from the beacon and the reception time when the beacon ID was received. In this example, the operation data also includes the vehicle-mounted device number that identifies the vehicle-mounted device 50 itself, and the crew ID that identifies the crew operating the work vehicle 60 on which the vehicle-mounted device is mounted.

Figure 6 is a flowchart showing the processing process by the server 20 according to the embodiment. The server 20 functions as a work amount calculation device that counts the number of times the vehicle-mounted device 50 travels between two points within a specified time. First, the receiving unit 22 of the server 20 receives the operation data of Figure 5 transmitted from the transmitting unit 52 of the vehicle-mounted device 50 via the network N (step S1). The server 20 acquires the operation data from the vehicle-mounted device 50 at regular intervals, such as once a day.

Next, the analysis unit 24 of the server 20 selects two beacons 40, for example a first beacon 40A and a second beacon 40B, from the received operation data (step S2). The selected beacons 40 are the beacons 40 at two locations where the number of round trips of the work vehicle 60 should be counted. The two beacons 40 are determined in advance by a user's input to the input unit 26. Alternatively, the user may select the two beacons 40 using the PC 10 or mobile terminal 30, and the receiving unit 22 may receive the beacon IDs of the two selected beacons 40 via the network N.

If two beacons 40 to be selected are present in the operation data (Yes in step S3), the analysis unit 24 first determines whether or not the first beacon 40A has been detected from the operation data (step S4). If the first beacon 40A has been detected (Yes in step S4), the analysis unit 24 determines that the first beacon ID (first identification information), which is the identification information of the first beacon 40A, has been received at the first time.

Next, the analysis unit 24 determines whether the second beacon 40B is detected at a second time within a predetermined time from the first time, i.e., the detection of the first beacon 40A, in the operation data (step S5). In other words, the analysis unit 24 determines whether the second beacon ID (second identification information), which is the identification information of the second beacon 40B, is received at the second time.

If the analysis unit 24 does not determine that the second beacon ID was received at a second time within the predetermined time from the first time (No in step S5), the analysis unit 24 again determines whether or not the first beacon 40A was detected from the operation data (step S4). On the other hand, if the analysis unit 24 determines that the second beacon ID was received at a second time within the predetermined time from the first time (Yes in step S5), the process proceeds to step S6. The analysis unit 24 determines whether or not the first beacon 40A was detected at a third time within the predetermined time from the detection of the second beacon 40B in the operation data, that is, whether or not the first beacon ID was received at the third time (step S6).

If it is not determined that the first beacon ID was received at the third time within the predetermined time from the second time (No in step S6), the analysis unit 24 again determines whether or not the first beacon 40A was detected from the operation data (step S4). Note that the first time to the third time in steps S4 to S6 correspond to the times at which the operation data was received.

When it is determined that the first beacon ID was received at the third time within a predetermined time from the second time (Yes in step S6), the analysis unit 24 calculates the number of round trips i that the work vehicle 60 made between the two points of the first beacon 40A and the second beacon 40B (step S7). This calculation is performed by counting in a manner that increments the number of round trips (i = i + 1) each time the first time to the third time in steps S4 to S6 are detected. The output unit 27 may output the calculated number of round trips i. In addition, the transmission unit 23 may transmit the calculated number of round trips i to the PC 10 and the mobile terminal 30 via the network N.

The analysis unit 24 further refers to the load per piece of luggage. This reference is made, for example, by the analysis unit 24 referring to a table stored in advance in the memory unit 25. This table associates time periods with the load per piece of luggage. "Load per piece of luggage" refers to the amount of luggage that the work vehicle 60 transports in one operation, such as the amount of luggage packed on one pallet.

Finally, the analysis unit 24 calculates the total load weight using the formula (total load weight = A x i) (step S9). In other words, the analysis unit 24 can calculate the total load weight transported by the work vehicle 60 between the two points.

As described above, if the first beacon ID is received at a first time (step S4), the second beacon ID is received at a second time after the first beacon ID is received (Yes in step S5), and the first beacon ID is again received at a third time after the second beacon ID is received (Yes in step S6), the analysis unit 24 increments the number of round trips by 1 (step S7).

This allows the server 20 to count the number of times the work vehicle 60 travels back and forth between the first point linked to the first beacon 40A and the second point linked to the second beacon 40B. Therefore, for example, it is possible to count the number of times that the work vehicle 60 loads cargo at the first point, transports the cargo to the second point, unloads it, and then returns to the first point. By automatically counting the number of round trips in this way, it is possible to grasp the workload of the crew in transporting cargo. It also becomes possible to evaluate the crew based on the workload.

The analysis unit 24 also performs the judgments of steps S5 and S6 separately, and if both are satisfied (Yes in steps S5 and S6), increments the number of round trips by 1. That is, the analysis unit 24 increments the number of round trips by 1 if the time from the first time to the second time is within a first predetermined time and the time from the second time to the third time is within a second predetermined time.

As a result, if the time it takes for the work vehicle 60 to go from the first point to the second point is within the first specified time, and the time it takes to return from the second point to the first point is within the second specified time, the number of round trips is counted. If the condition is not met, such as if the movement between the first point and the second point is not completed within the specified time because another point was passed through, the number of round trips is not counted. Therefore, for example, because movements that pass through points other than the two specified points can be excluded from the number of round trips, it is possible to accurately grasp the number of round trips corresponding to the number of loads transported between the two target points. The first specified time and the second specified time may be different from each other or the same.

The server 20 also includes an input unit (input unit 26) that accepts input for selecting any two of the multiple beacons 40 placed within the facility as the first beacon 40A and the second beacon 40B. This allows the number of round trips between any two points selected by the user to be counted when the beacons 40 are placed at multiple points within the facility. However, the receiving unit 22 of the server 20 may receive input of the first beacon 40A and the second beacon 40B corresponding to the two points selected by the user from an external device such as a PC 10 or a mobile terminal 30, which also provides the same effect.

The analysis unit 24 also calculates the total load based on the load per piece of luggage and the number of round trips (step S8). As a result, if the same amount of luggage is transported each time, the total load can be found by calculating the product of the load per piece of luggage and the number of round trips. This makes it possible to determine the total amount of luggage transported by the crew.

Furthermore, the output unit 27 of the server 20 can output the calculated number of round trips. As a result, the output unit 27 can display the number of round trips counted by the analysis unit 24, for example, on a screen, thereby making it possible to grasp the workload of the crew.

The transmission unit 23 of the server 20 may transmit the calculated number of round trips. In this way, the transmission unit 23 can transmit the number of round trips counted by the analysis unit 24 to the PC 10, mobile terminal 30, etc., thereby making it possible to grasp the workload of the crew.

Figure 7 is a flowchart showing another processing process by the server 20 according to the embodiment. In this process, steps S5A and S6A are executed instead of steps S5 and S6 in Figure 6.

In step S5 of FIG. 6, the analysis unit 24 determines whether or not a second beacon ID is received at a second time within a predetermined time from the first time. On the other hand, in step S5A, the analysis unit 24 determines only whether or not a second beacon B is detected at a second time after detecting the first beacon 40A, and does not determine whether or not this second time is within a predetermined time from the first time.

When the analysis unit 24 detects the second beacon 40B at the second time after detecting the first beacon 40A (Yes in step S5A), the process proceeds to step S6A. The analysis unit 24 determines whether the first beacon 40A is detected again in the operation data at a third time within a predetermined time from the initial detection of the first beacon 40A, that is, whether the first beacon ID is received at the third time (step S6A). If it is determined that the first beacon ID is received again at a third time within a predetermined time from the first time (Yes in step S6A), the analysis unit 24 calculates the number of round trips i that the work vehicle 60 has made between the two points of the first beacon 40A and the second beacon 40B (step S7). The rest is the same as in FIG. 6.

That is, when the analysis unit 24 receives the second beacon ID at a second time after the first time (Yes in step S5A) and receives the first beacon ID at a third time within a predetermined time from the first time (Yes in step S6A), the analysis unit 24 increments the number of round trips by 1. That is, when the time from the first time to the third time is within a predetermined time, the analysis unit 24 increments the number of round trips by 1, and when the time from the first time to the third time exceeds the predetermined time, the analysis unit 24 does not increment the number of round trips.

In this way, the server 20 does not count the number of round trips when the time required for a round trip is longer than a predetermined time, and can therefore exclude, for example, movements that pass through locations other than the two specified locations from the number of round trips. This allows the server 20 to accurately grasp the number of round trips that corresponds to the number of times luggage is transported between the two target locations.

The workload management system 100 of the embodiment includes a server 20, an in-vehicle device 50, a first beacon 40A, and a second beacon 40B. The in-vehicle device 50 has a memory unit 53 that stores operation data, and a transmission unit 52 that transmits the operation data to the server 20, and in the server 20, a receiving unit 22, which is a data acquisition unit, receives and acquires the operation data.

As a result, the vehicle-mounted device 50 transmits operation data to the server 20, and the server 20 can calculate the number of round trips by analyzing the received operation data. Therefore, the crew manager, etc. does not need to load the operation data into the workload calculation device via a memory card, etc. Therefore, the server 20 makes it easy to know the number of times the work vehicle 60 has made a round trip between the first point linked to the first beacon 40A and the second point linked to the second beacon 40B. In this way, by automatically counting the number of round trips in the server 20, it is possible to easily know the workload of the crew in carrying luggage. In addition, it becomes possible to evaluate the crew based on the workload.

The process of grasping the amount of work described above is executed by the control unit 21, which is a computer of the server 20, reading out a work amount calculation program in which such a process is programmed. The control unit 21 can read out the work amount calculation program stored in the memory unit 25, for example, and calculate the amount of work as shown in Figures 6 and 7.

In the above embodiment, the server 20 receives one day's worth of operation data from the vehicle-mounted device 50, but the timing at which the server 20 receives the operation data from the vehicle-mounted device 50 is not limited. For example, the server 20 may receive operation data from the vehicle-mounted device 50 when the driver is changed, or, if the server 20 and the vehicle-mounted device 50 are capable of communicating in real time, the server 20 may receive operation data each time the vehicle-mounted device 50 updates the operation data.

In addition, in the embodiment, the server 20 receives the operation data directly from the vehicle-mounted device 50, but the server 20 may obtain the operation data from the vehicle-mounted device 50 via a communication terminal such as the PC 10. For example, the operation data may be stored in a memory card in the vehicle-mounted device 50, and the communication terminal may read the memory card to obtain the operation data and transmit it to the server 20, and the server 20 may receive the operation data.

Here, the features of the embodiments of the workload calculation device, workload management system, and workload calculation program according to the present invention described above are briefly summarized and listed below in [1] to [10].

[1] A data acquisition unit (receiver 22) that acquires operational data recorded by an on-board device (50) mounted on a work vehicle (60), the operational data including identification information of a transmitter (beacon 40) and a time of receipt of the identification information;
and an analysis unit (24) that analyzes the operation data and increments the number of round trips by 1 when first identification information, which is identification information of a first transmitter (first beacon 40A), is received at a first time, and after receiving the first identification information, second identification information, which is identification information of a second transmitter (second beacon 40B), is received at a second time, and after receiving the second identification information, the first identification information is received at a third time.
Work load calculation device (server 20).

According to the workload calculation device of the configuration [1] above, it is possible to count the number of times a work vehicle travels back and forth between a first point linked to a first transmitter and a second point linked to a second transmitter. Therefore, for example, it is possible to count the number of times a work vehicle loads a load at a first point, transports the load to a second point, unloads it, and then returns to the first point. By automatically counting the number of round trips in this way, it is possible to grasp the workload of the crew in transporting the load. It is also possible to evaluate the crew based on the workload.

[2] The analysis unit increments the number of round trips by 1 when a time from the first time to the third time is within a predetermined time, and does not increment the number of round trips when the time from the first time to the third time exceeds the predetermined time.
The workload calculation device according to [1] above.

According to the work amount calculation device having the configuration of [2] above, if the time required for a round trip is longer than a predetermined time, the number of round trips is not counted, so that, for example, movements via locations other than the two specified locations can be excluded from the number of round trips. Therefore, with this work amount calculation device, it is possible to accurately grasp the number of round trips corresponding to the number of times a load is carried between the two target locations.

[3] The analysis unit increments the number of round trips by 1 when a time from the first time to the second time is within a first predetermined time and a time from the second time to the third time is within a second predetermined time.
The workload calculation device according to [1] above.

According to the work amount calculation device having the configuration of [3] above, if the time it takes for the work vehicle to go from the first point to the second point is within a first predetermined time, and the time it takes to return from the second point to the first point is within a second predetermined time, the number of round trips is counted, but if the condition is not met, such as movement via another point, it is not counted as a round trip. Therefore, for example, movement via a location other than the two specified locations can be excluded from the number of round trips, so that the number of round trips corresponding to the number of loads transported between the two target locations can be accurately determined.

The workload calculation device according to any one of [1] to [5] above.

According to the work amount calculation device configured as in [6] above, when the same amount of luggage is transported each time, the total load amount can be calculated by multiplying the load amount per piece of luggage by the number of round trips. This makes it possible to grasp the total amount of luggage transported by the crew.

[7] An output unit (27) for outputting the number of reciprocations,
The workload calculation device according to any one of [1] to [6] above.

According to the workload calculation device having the configuration of [7] above, the output unit displays the number of round trips counted by the analysis unit, for example, on a screen, so that the workload of the crew can be grasped.

[8] A transmitter (23) for transmitting the number of round trips,
The workload calculation device according to any one of [1] to [6] above.

According to the workload calculation device having the configuration of [8] above, the number of round trips counted by the analysis unit is transmitted by the transmission unit to a communication terminal, so that the workload of the crew can be ascertained. Examples of communication terminals include a PC or mobile terminal that is placed in the office of the transportation company and operated by a manager.

[9] A server (20) that functions as the work amount calculation device according to any one of [1] to [8] above, the vehicle-mounted device, the first transmitter, and the second transmitter,
The vehicle-mounted device includes:
A storage unit (53) for storing the operation data;
A transmission unit (52) that transmits the operation data to the server,
In the server,
The data acquisition unit acquires the operation data by receiving the operation data.
Workload management system.

According to the workload management system configured as in [9] above, the vehicle-mounted device transmits operation data to a server, and the server can calculate the number of round trips by analyzing the received operation data. Therefore, crew managers, etc. do not need to load operation data into the workload calculation device via a memory card or the like. Therefore, it is possible to easily grasp the number of times the work vehicle has made a round trip between a first point linked to the first transmitter and a second point linked to the second transmitter. By automatically counting the number of round trips in this way, it is possible to easily grasp the workload of the crew in transporting cargo. In addition, it becomes possible to evaluate the crew based on the workload.

[10] A step of acquiring operation data recorded by an on-board device (50) mounted on a work vehicle (60), the operation data including identification information of a transmitter (beacon 40) and a time of receiving the identification information;
a step of analyzing the operation data, and incrementing the number of round trips by 1 when first identification information, which is identification information of a first transmitter (first beacon 40A), is received at a first time, and after receiving the first identification information, second identification information, which is identification information of a second transmitter (second beacon 40B), is received at a second time, and after receiving the second identification information, the first identification information is received at a third time;
A work amount calculation program that causes a computer to execute the above.

According to the workload calculation program of the configuration [10] above, it is possible to count the number of times a work vehicle travels back and forth between a first point linked to a first transmitter and a second point linked to a second transmitter. Therefore, for example, it is possible to count the number of times a work vehicle loads a load at a first point, transports the load to a second point, unloads it, and then returns to the first point. By automatically counting the number of round trips in this way, it is possible to grasp the workload of the crew in transporting the load. It is also possible to evaluate the crew based on the workload.
