Description

The present invention relates to a mobile terminal device, a visit confirmation system and a program, and in particular, management of visits to facilities of workers.

Workers go to the facility and maintain equipment such as elevators according to the contract with the customer. At this time, various methods have been conventionally used in order to prevent omission of visits. For example, the connection information between elevators and escalators that are subject to maintenance and maintenance tools installed in the mobile terminal devices of workers is recorded in the mobile terminal device and notified to the information center that manages maintenance work or reported after returning to work. To do. Alternatively, the operator operates the operating means of the elevator to transmit the information from the elevator to the information center. In addition, a technology has been proposed in which an IC tag installed on an elevator is read by a mobile terminal device having a reader function and transmitted to a management system (for example, Patent Document 1).

Workers record and report that they have visited the facility by any of the methods described above, depending on the specifications of the elevator and the installation environment.

The mobile terminal device 10 is a terminal device that is carried when a maintenance staff visits the building 1. The maintenance staff dispatches from the office 4 according to the maintenance schedule, visits each building 1 in order according to the schedule information, and performs predetermined maintenance work. Then, when the maintenance work on the day is completed, the office returns to the office 4. In FIG. 1, the movement of the worker is indicated by an arrow. It should be noted that each worker carries the portable terminal device 10 when going to the building 1 and patrolles each building 1 according to his or her own schedule, so only one worker is shown in FIG.

FIG. 2 is a hardware configuration diagram of the mobile terminal device 10 according to the present embodiment. In the present embodiment, a case where a smartphone is used as the mobile terminal device 10 is assumed and described. It should be noted that the hardware configuration not used in the description of the present embodiment is omitted from FIG. 2. The mobile terminal device 10 in the present embodiment is a general-purpose hardware configuration that has been equipped with a computer and has existed before. realizable. That is, as shown in FIG. 2, the mobile terminal device 10 includes a CPU 21, a ROM 22, a RAM 23, a storage 24, an operation panel 25 provided as a user interface unit, a network interface (IF) 26 provided as a communication unit, and a positioning unit. A GPS (Global Positioning System) 27 serving as a sensor and an acceleration sensor 28 serving as a sensor unit are connected to an internal bus 29.

The mobile terminal device 10 according to the present embodiment includes a movement detection unit 11, a movement record information generation unit 12, a movement record information notification unit 13, a reference movement pattern storage unit 14, and a movement record information storage unit 15. Note that components not used in the description of the present embodiment are omitted from FIG. The movement detection unit 11 detects the movement pattern of the worker by analyzing the output from the acceleration sensor 28, and compares the detected movement pattern with the reference movement pattern registered in the reference movement pattern storage unit 14. The movement of the worker using the elevator is detected by. The movement record information generation unit 12 generates movement record information when the movement detection unit 11 detects movement of the worker using the elevator, and writes and stores the movement record information in the movement record information storage unit 15. The movement record information notification unit 13 notifies the movement record information stored in the movement record information storage unit 15 to the monitoring server installed in the monitoring center 3.

FIG. 4 is a diagram showing an example of the data structure of the movement record information stored in the movement record information storage unit 15 in the present embodiment. The movement record information includes date and time and position information. The date and time is date and time information indicating the date and time when the movement of the worker using the elevator is detected. The position information is information indicating the detected position of the movement. In this embodiment, the latitude and longitude information obtained from the GPS 27 is used as the position information. When the movement record information is sent from the mobile terminal device 10 to the monitoring server 30, the identification information of the worker or the mobile terminal device 10 and the information such as the transmission date and time are added to individually identify the worker. ..

5A and 5B are conceptual diagrams showing the reference movement patterns preset in the reference movement pattern storage unit 14 in the present embodiment. Here, when an elevator is assumed to be used as the elevator, the operation when the elevator moves up and down is basically uniform. That is, as shown in FIG. 5A, although the moving time (time length between t4 and t5) of the elevator at a constant speed varies depending on the number of floors to move, the speed and acceleration when the elevator starts to rise. The speed and acceleration for stopping at the designated stop floor are predetermined by the elevator, and the elevator is controlled to operate in the ascending direction according to the setting. This is
The same applies to the operation of the elevator in the descending direction shown in B. Note that if the specifications of the elevators subject to maintenance management are different, the inclinations and magnitudes of acceleration and speed, and the time length between t2 and t3 in FIG. 5A may change. A reference movement pattern may be prepared for each.

Also, even in the reference movement pattern of the escalator that moves diagonally with respect to the vertical direction of the elevator, the inclination of acceleration or the degree of plus or minus may differ from that of the elevator, but basically, FIG. 5A and FIG. It has the same shape as the reference movement pattern shown in FIG.

Each of the components 11 to 13 in the mobile terminal device 10 is realized by a cooperative operation of a computer installed in the mobile terminal device 10 and a program operating by the CPU 21 installed in the computer. The storage units 14 and 15 are realized by the storage 24 installed in the mobile terminal device 10. Alternatively, the RAM 23 or an external storage unit may be used via the network.

FIG. 6 is a hardware configuration diagram of a server computer forming the monitoring server 30 according to the present embodiment. The monitoring server 30 is a server computer that is installed in the monitoring center 3 and is used to perform visit management such as monitoring of workers' omissions to the facility. The server computer forming the monitoring server 30 in the present embodiment can be realized by a general-purpose hardware configuration that has existed before. That is, the computer connects the CPU 41, the ROM 42, the RAM 43, the hard disk drive (HDD) 44, the mouse 45 and keyboard 46 provided as input means, and the display 47 provided as a display device, as shown in FIG. An input/output controller 48 and a network interface (IF) 49 provided as a communication means are connected to the internal bus 50.

FIG. 7 is a block configuration diagram of the monitoring server 30 in the present embodiment. The monitoring server 30 in the present embodiment has a movement record information acquisition unit 31, a visit omission detection unit 32, a visit omission notification unit 33, a schedule information storage unit 34, and a movement record information storage unit 35. Note that constituent elements not used in the description of the present embodiment are omitted from FIG. 7. The movement record information acquisition unit 31 acquires the movement record information sent from each mobile terminal device 10 and stores it in the movement record information storage unit 35. The missed visit detection unit 32 collates the position of the facility scheduled to be visited by the worker, which is identified based on the schedule information preset in the schedule information storage unit 34, with the acquired movement record information to visit the worker. Detect missed visits to the planned building 1. When the visit omission detection unit 32 detects the omission of the visit, the visit omission notification unit 33 notifies the visit omission by transmitting the content to a terminal device (not shown) used by the administrator or the like.

In the schedule information storage unit 34, the identification information of the building 1 to be visited by each worker, the location information for identifying the location, and the schedule information in which at least the order of visit are specified are registered. The location information may be information indicating the storage location of the information in which the address of the building 1 is described. The location information does not necessarily have to be included in the schedule information storage unit 34, and the location information may be retrieved and acquired based on the identification information of the building 1.

Each of the components 31 to 33 in the monitoring server 30 is realized by the cooperative operation of the computer forming the monitoring server 30 and the program operating by the CPU 41 installed in the computer. The storage units 34 and 35 are realized by the HDD 44 mounted on the monitoring server 30. Alternatively, the RAM 43 or an external storage unit may be used via the network.

Further, the program used in the present embodiment is, of course, provided by communication means,
It is also possible to store it in a computer-readable recording medium such as a CD-ROM, a USB memory, or a card type memory, and provide it. The program provided from the communication unit or the recording medium is installed in the computer, and the CPU of the computer sequentially executes the program to realize various processes.

On business days, the worker visits the building 1 in the designated order according to the setting contents of the schedule information and performs maintenance work. It is premised that the worker carries the mobile terminal device 10 when going to the site, that is, the building 1 to be visited, and when carrying out further maintenance work, he/she always rides on the elevator to be maintained for safety confirmation work and the like. There is. Hereinafter, movement detection processing by the elevator that operates in the mobile terminal device 10 while the worker is patroling the building 1 to be visited will be described with reference to the flowchart shown in FIG.

The application that executes this process is started when the worker moves out of the office 4. The GPS 27 of the mobile terminal device 10 constantly detects the current position of the worker by positioning. The acceleration sensor 28 of the mobile terminal device 10 constantly detects acceleration.

The movement detection unit 11 constantly acquires the output from the acceleration sensor 28 and generates the movement pattern of the worker (step 101). Since the elevator operates mechanically, it operates at a predetermined moving speed and acceleration. That is, the moving speed and the acceleration can be increased or decreased by a fixed amount. On the other hand, it is difficult for human beings to keep constant speed and acceleration like a machine even if they move at the same speed, and it slightly fluctuates. That is, when a person walks or moves using some moving means other than an elevator such as a vehicle, a movement pattern having a uniform shape such as the reference movement pattern illustrated in FIGS. 5A and 5B is used. Should not be. In other words, if the movement pattern generated based on the movement of the worker is a mechanical reference movement pattern such as the reference movement pattern illustrated in FIGS. 5A and 5B, it means that the worker is moving himself. It is thought that the elevator is used to move instead of the no. The present embodiment is characterized by focusing on the difference in the pattern shape between the movement using the elevator and the movement not using the elevator.

Therefore, the movement detection unit 11 collates the generated movement pattern of the worker with each reference movement pattern registered in the reference movement pattern storage unit 14 (step 102). Note that, as described above, the length of the reference movement pattern, for example, the time length between t4 and t5 in FIG. 5A varies depending on the number of floors the elevator moves, so it is necessary to adjust this time length when performing matching. Will occur. Further, for simplicity, a constant speed may be detected and collated.

Then, as a result of the collation, when the movement pattern of the worker does not match any of the reference movement patterns registered in the reference movement pattern storage unit 14 (N in step 103), the movement detection unit 11 does not use the elevator. Judge as moving. This application is not terminated until the worker returns to the office 4 (N in step 105), and the process returns to step 101.

On the other hand, as a result of the collation, when the movement pattern of the worker matches any of the reference movement patterns registered in the reference movement pattern storage unit 14 (Y in step 103), the movement detection unit 11 moves using the elevator. To judge. When the movement using the elevator is detected, the movement record information generating unit 12 acquires the current position from the GPS 27, generates the movement record information including the detection date and time and the current position of the movement, and moves the movement record information storage unit 15 It is written in and saved in (step 104). Then, as described above, the above processing is repeated until the office 4 is returned to.

When the worker returns to the office 4 after the maintenance work for the current day ends, the worker ends the application (Y in step 105).

Subsequently, when the mobile terminal device 10 is connected to the monitoring server 30 by wire or wirelessly, the movement record information notification unit 13 transmits the movement record information stored in the movement record information storage unit 15 to the monitoring server 30. .. When transmitting, the identification information of the worker or the mobile terminal device 10 is added so that the worker who worked can be specified.

When the movement record information acquisition unit 31 in the monitoring server 30 acquires the movement record information transmitted from the mobile terminal device 10, the movement record information acquisition unit 31 writes and stores the movement record information in the movement record information storage unit 35. Next, the visit omission detection unit 32 actually visits the visited place by collating the acquired movement record information with each position information of the visited place (building 1) included in the schedule information of the worker. To find out. When the visit omission detection unit 32 detects a visit omission, the visit omission notification unit 33 notifies the content by transmitting the content to the terminal device used by the administrator or the like.

Here, a method of detecting a visit leakage in the visit leakage detecting unit 32 will be described with reference to FIG.

FIG. 9A is a diagram when the worker plots each position 2 using the elevator in a certain space based on the position information included in the movement record information registered in the movement record information storage unit 35. According to the date and time information included in the movement record information, the position 2 where the worker uses the elevator has moved counterclockwise from the position 2a to reach the position 2n.

9B, the building 1 and the office 4 shown in FIG. 1 are applied to FIG. 9A. Then, as shown by the broken line, the position where the plotted positions 2 are connected in time series is the movement path of the worker. Of course, in the case of the present embodiment, the information for guiding the travel route is only the position information included in the travel record information, and therefore the travel route shown by the broken line is based on estimation. As can be understood from FIG. 9B, it can be understood that the worker dispatched from the office 4 according to the schedule information and visited the buildings 1a, 1c and 1d in order. Then, as shown in the position 2d, it can be seen that the worker used the elevator in the building 1d. That is, it can be confirmed that the worker visited the building 1d. In the buildings 1a and 1c, a plurality of positions are plotted, which means that the elevator has been used a plurality of times. It is considered that the same elevator is used a plurality of times and that a plurality of elevators are used. On the other hand, the position 2 is not plotted in the building 1b. This means that no workers are visiting the building 1b. This corresponds to a visit omission. Although the position 2e does not correspond to the building 1, this means that the worker used, for example, an elevator or an escalator of a building other than the station or the maintenance target.

The visit omission detection unit 32 collates the position specified from the movement record information with the position of the building 1 to be maintained in this way, and, for example, within a few tens of meters from the position information (longitudinal information) of the building 1, If the use is confirmed, the worker determines that he/she visited the building 1. On the other hand, like the building 1b, if the position information (longitude and latitude information) of the building 1 is not plotted within tens of meters, the worker determines that the building 1 has not been visited. The tens of meters is a range that serves as a criterion for determining whether or not a worker has visited the building 1. The range used as the criterion may be set appropriately.

According to the present embodiment, as described above, the position where the worker uses the elevator is extracted as a candidate for the position where the worker performs maintenance, and the position of the building 1 is set to any of the extracted positions. If so, the worker can confirm that he/she visited the building 1. Since it is not necessary for the worker to perform any operation, the worker does not miss the report of the visit.

Strictly speaking, the worker may simply use the elevator in the building 1 without performing maintenance work on the elevator to be maintained. That is, it is possible that the intended maintenance work may not have been performed, but in the present embodiment, it can be confirmed that at least the building 1 in which the elevator to be maintained is installed is visited.

Embodiment 2.
FIG. 10 is a block configuration diagram of the mobile terminal device 10 according to the present embodiment. In the present embodiment, the hardware configuration of the mobile terminal device 10, the hardware configuration and the block configuration of the monitoring server 30 may be the same as in the first embodiment. The mobile terminal device 10 according to the present embodiment includes a movement record information generation unit 16, a movement detection unit 17, a movement record information notification unit 13, a reference movement pattern storage unit 14, and a movement record information storage unit 15. The same components as those in the first embodiment will be assigned the same reference numerals and explanations thereof will be omitted. Further, as in the first embodiment, constituent elements not used in the description of the present embodiment are omitted from FIG. The movement record information generation unit 16 in the present embodiment periodically acquires the current position from the GPS 27 and generates the movement record information including at least the current position. The movement detection unit 17 stores, in the reference movement pattern storage unit 14, the movement pattern of the worker obtained by analyzing the output from the acceleration sensor 28 when the movement record information generation unit 16 generates the movement record information. The movement of the worker using the elevator is detected by collating with the set reference movement pattern. When detected, the detection information indicating that the movement is detected is added to the movement record information.

FIG. 11 is a diagram showing an example of the data structure of the movement record information stored in the movement record information storage unit 15 in the present embodiment. The movement record information in the present embodiment is configured by adding a use flag as detection information to the movement record information in the first embodiment.

Each of the components 13, 16 and 17 in the mobile terminal device 10 is realized by a cooperative operation of a computer installed in the mobile terminal device 10 and a program operating by the CPU 21 installed in the computer.

Next, movement detection processing by the elevator in the mobile terminal device 10 will be described with reference to the flowchart shown in FIG. In addition, the same step number is assigned to the same processing step as that of the first embodiment, and the description will be appropriately omitted.

When the application that executes this process is activated when the worker is dispatched, the GPS 27 of the mobile terminal device 10 constantly detects the current position of the worker by positioning. The acceleration sensor 28 of the mobile terminal device 10 constantly detects acceleration.

The movement record information generation unit 16 periodically acquires the current position from the GPS 27, generates the movement record information including the acquired date and time and the current position and writes the movement record information in the movement record information storage unit 15 every time the acquisition is performed. Save (step 201). The use flag is initially set to clear that the elevator is not used. The cycle of acquiring the current position and generating the movement record information may be set appropriately with reference to the storage capacity of the movement record information storage unit 15 and the like.

When the movement record information generation unit 16 generates the movement record information, the movement detection unit 17 generates the movement pattern of the worker based on the output from the acceleration sensor 28 which is constantly acquired (step 101). Then, the movement detection unit 17 collates the generated movement pattern of the worker with each reference movement pattern registered in the reference movement pattern storage unit 14 (step 102). As a result of collation, when the movement pattern of the worker does not match any of the reference movement patterns registered in the reference movement pattern storage unit 14 (N in step 103), the movement detection unit 11 determines the point where the movement record information is generated. Then, it is judged that the movement does not use the elevator. This application is not terminated until the worker returns to the office 4 (N in step 105), and the process returns to step 201.

On the other hand, as a result of the collation, when the movement pattern of the worker matches any of the reference movement patterns registered in the reference movement pattern storage unit 14 (Y in step 103), the movement detection unit 17 moves the movement using the elevator. Then, the use flag corresponding to the movement record information is set (step 202).

When the worker returns to the office 4 after the maintenance work for the current day ends, the worker ends the application (Y in step 105). Then, as in the first embodiment, the movement record information notification unit 13 transmits the movement record information stored in the movement record information storage unit 15 to the monitoring server 30.

The operation of the monitoring server 30 is basically the same as that of the first embodiment. However, in the first embodiment, only the movement record information corresponding to the position where the use of the elevator is detected is generated, whereas in the present embodiment, the movement record information has a fixed cycle regardless of whether the elevator is used. Have been generated. Therefore, the visit omission detection unit 32 identifies the use position of the elevator by referring to the use flag included in the movement record information.

In the first embodiment described above, only the position where the use of the elevator is confirmed is plotted, and therefore the movement route shown by the broken line in FIG. 9B is based on the estimation. On the other hand, in the present embodiment, since the movement record information is periodically generated as described above, it is possible to specify the movement route of the worker by plotting based on the movement record information. Then, the position where the elevator is used is plotted on the movement path.

According to the present embodiment, like the first embodiment, it is possible to detect the omission of the visit by the worker. Also, the movement route of the worker can be confirmed. Furthermore, since it becomes possible to confirm the residence time at one point, it becomes possible to estimate the working time. On the other hand, since the movement record information is generated at regular intervals, the storage capacity required for recording the movement record information increases.

In each of the above-described embodiments, the terminal device used by the administrator or the like is the output destination of the omission of the visit and the report of the building 1 or the like that has missed the visit. The output destination may be storage means or may be transmitted to the outside via a network.

Further, although cases have been described with the above embodiment as examples where an acceleration sensor is used as the sensor unit, an atmospheric pressure sensor may be used instead of the acceleration sensor, or each sensor may be used in combination.

Further, in each of the above-described embodiments, the acceleration and the speed are prepared as the reference movement pattern, but at least one of them may be used.
