  Hereinafter, embodiments of a maintenance staff position information management system will be described with reference to the drawings.

(1) Configuration of Maintenance Person Location Information Management System According to the Present Embodiment FIG. The maintenance staff location information management system 1 manages the mobile terminal 10 that is a terminal that transmits location information through the public network 20 and the maintenance staff 15 having the mobile terminal 10, communicates with the sales office 40, and the maintenance staff 15 It comprises a monitoring center 30 that is a management device that monitors the site 50 where the equipment 50C to be maintained for maintenance work is installed and receives position information.

  A facility 50C controlled by the control device 50A is installed at the site 50, and a display device 50B that is an image device used by the user is disposed in the facility 50C. The remote monitoring device 50D is provided to remotely monitor the control device 50A for any abnormality from the monitoring center 30. When there is an abnormality, the monitoring center 30 receives a report such as confinement from the site 50 and transmits a report such as confinement site information to the mobile terminal 10. For example, in the case of a site 50 where an elevator is installed, the facility 50C is a car, and when an abnormal stop occurs, the monitoring center 30 automatically receives a report such as confinement from the control device 50A, and the information on the confinement site etc. Send a report. Note that a notification such as confinement may be transmitted to the monitoring center 30 when a passenger in the passenger car 50C presses a notification button installed in the passenger car 50C.

  The position information management server 31, which is a forming module that forms an image showing the transition of position information of the monitoring center 30, receives the position information by the position information receiving device 31 </ b> A, and displays position information based on the received position information. The image data of the map in which the position information of the maintenance staff 15 is displayed on the device 31B is created.

  The position information display device 31B is connected to a PC 41 which is a personal computer or the like in the sales office 40 where the maintenance staff 15 goes to work before the work starts or after the work ends. For this reason, the administrator 42 in the sales office 40 can confirm the position of the maintenance staff 15 via the PC 41.

  The monitoring server 32 of the monitoring center 30 receives a report such as confinement from the site 50 by the data receiving device 32A, which is a communication device, and determines whether the equipment 50C is a model that can display image data on the display device 50B. If the model can be displayed, the image display determination device 32C acquires the image data from the position information display device 31B, transmits the acquired image data to the site 50 through the data transmission device 32B, which is a communication device, and the public Image data is displayed on the display device 50B via the line network 20, the communication device 50E, the remote monitoring device 50D, and the control device 50A.

  The maintenance staff 15 inputs to the mobile terminal 10 according to his / her situation. This input may be input by the maintenance staff 15 by operating a button or a touch panel, or may be automatically input according to the distance from the site 50 or the sales office 40.

  As shown in the input column T11 of the status data table T1 in FIG. 2, the types of inputs that are the status of the maintenance staff 15 include “departure”, “work in progress”, “exit”, and “return”. As shown in the status column T12, the status data table T1 is associated with the statuses corresponding to the maintenance staff 15 of “moving”, “working”, “moving”, and “stopped”, respectively. . Note that the response status includes “moving” in which the maintenance staff 15 is moving with respect to the maintenance target, “work in progress” in which the maintenance staff 15 is performing maintenance work on the maintenance target, and “stop” In addition to “,” there is “emergency” that the maintenance staff 15 to be described later should urgently maintain the maintenance target. The status data table T1 is stored in the memory 12 described later.

  Here, the case where the maintenance staff 15 leaves the sales office 40, maintains the site A51 and the site B52, and returns to the sales office 40 will be described. When the maintenance staff 15 leaves the sales office 40, the maintenance staff 15 operates the portable terminal 10 and inputs “departure”. With this input, the mobile terminal 10 transmits the position information immediately after this input, and starts transmitting the position information in the transmission cycle when the status is “moving”. When the maintenance staff 15 arrives at the site A51, the maintenance staff 15 operates the portable terminal 10 and inputs “entry”. With this input, the mobile terminal 10 transmits the position information immediately after this input, and starts transmitting the position information in the transmission cycle when the status is “working”. When the work at the site A51 is completed, the maintenance staff 15 operates the portable terminal 10 and inputs “Exit”. With this input, the mobile terminal 10 transmits the position information immediately after this input, and starts transmitting the position information in the transmission cycle when the status is “moving”.

  When the maintenance staff 15 arrives at the site B52, the maintenance staff 15 operates the portable terminal 10 and inputs “entry”. With this input, the mobile terminal 10 transmits the position information immediately after this input, and starts transmitting the position information in the transmission cycle when the status is “working”. When the work at the site B51 is completed, the maintenance staff 15 operates the portable terminal 10 and inputs “Exit”. With this input, the mobile terminal 10 transmits the position information immediately after this input, and starts transmitting the position information in the transmission cycle when the status is “moving”. When the maintenance staff 15 arrives at the sales office 40, the maintenance staff 15 operates the mobile terminal 10 and inputs “return”. As a result of this input, the status of the portable terminal 10 becomes “stop”, and transmission of position information is stopped.

  Note that the above-described content is an example, and “return” may be automatically input to the mobile terminal 10 when the mobile terminal 10 approaches a certain distance of the sales office 40, or the mobile terminal 10 may “Working” may be automatically input to the mobile terminal 10 when the mobile terminal 10 approaches a certain distance, or when the mobile terminal 10 moves away from the fixed distance between the sales office 40 and the work site 50, “ “Moving” may be input to the mobile terminal 10. Further, in the above-described contents, the mobile terminal 10 transmits the position information even when “working”, but does not need to transmit the position information when “working”. . In addition, when the maintenance staff 15 starts maintenance at the site 50 and detects the establishment of communication connection between the communication device 50E and the portable terminal 10 (completion of communication connection when maintenance is completed), the detection result is sent to the monitoring center 30 or the mobile phone. By entering the terminal 10, entry / exit information of “entry” and “exit” may be determined.

  According to the transmission cycle data table T2 of FIG. 2, the statuses “moving”, “working”, “emergency”, and “stop” shown in the status column T21 are the transmission cycles “10” shown in the transmission cycle column T22. ”,“ 60 ”,“ 1 ”, and“ 0 ”, respectively. The transmission cycle data table T2 is stored in the memory 12 described later. The relationship between the values of the transmission cycle between the statuses is that the value of the “working” transmission cycle is the largest, the value of the “moving” transmission cycle is next, and the value of the “emergency” transmission cycle is The value shall be the smallest. Note that the transmission period of “stop” is “0”, and when “0” is set as the value of the transmission period, the mobile terminal 10 does not transmit the position information.

The mobile terminal 10 held by the maintenance staff 15 is a CPU (Central
CPU 11 such as Processing Unit (MPU) or Micro Processor Unit, DRAM (Dynamic RAM), RAM (Random Access Memory) or ROM (Read Only Memory) storing various data and programs necessary for processing of CPU 11 And a communication device 14 for the CPU 11 to communicate with a monitoring center 30 outside the portable terminal 10.

  The memory 12 includes a transmission cycle setting program 12A for performing a transmission cycle setting process for setting a transmission cycle based on the transmission cycle data table T2, and a maintenance for performing a maintenance worker work state input reception process for receiving an input of a work state of the maintenance staff 15. A worker work state input reception program 12B, a maintenance worker work state management program 12C for performing maintenance worker work state management processing for managing the maintenance worker's work state, and position information transmission determination processing for determining whether to transmit position information. A position information transmission determination program 12D, a position information measurement program 12E for measuring a position using a GPS or a base station of the mobile terminal 10, a position information transmission program 12F for transmitting position information, and a report of confinement site information, etc. And a site information receiving program 12G for receiving. The memory 12 includes the above-described status data table T1 and transmission cycle data table T2.

  Here, the transmission cycle setting program 12A, the maintenance worker work state input reception program 12B, and the position information transmission program 12F are programs. However, the control module, the input module, and the position information for setting the position information transmission cycle are transmitted. The maintenance module work state management program 12C, the position information transmission determination program 12D, the position information measurement program 12E, and the on-site information reception program 12G may be modules.

(2) Processing in Mobile Terminal FIG. 3 shows a flowchart of processing in the mobile terminal 10. The mobile terminal 10 receives an input of the work status of the maintenance staff 15, and enters a maintenance staff work status input reception process and a maintenance staff work status management process (SP 10) for managing the work status of the maintenance staff 15, and the transmission cycle data table T 2. A transmission cycle setting process (SP20) for setting a transmission cycle based on the above, an emergency response process (SP30) for determining whether there is an emergency call such as confinement site information from the monitoring server 32, and setting an emergency transmission cycle; A position information transmission determination process (SP40) for periodically transmitting position information is performed. Note that the above-described series of processing of SP10 to SP40 shown in FIG. 3 is processed periodically (for example, every one minute) at regular intervals by processing such as timer interruption.

  FIG. 4 shows a flowchart of maintenance worker work state input acceptance processing and maintenance worker work state management processing (SP10). First, the type of input is determined by the maintenance worker work state input receiving program 12B (SP11). The type of input here is determined, for example, when the maintenance staff 15 selects an input state from the touch panel of the mobile terminal 10 or the like.

  Next, the maintenance worker work state management program 12C refers to the status data table T1 and sets a status according to the determination result (SP12 to SP14).

  In the description of step SP12 to step SP14 and the status data table T1, there is no “emergency” in the input. However, instead of the emergency response process (SP30), the maintenance staff 15 receives from the monitoring center 30 or the administrator 42. When receiving a notification, the user may input “emergency” by himself and set the status to “emergency”.

  FIG. 5 shows a flowchart of the transmission cycle setting process (SP20). The transmission cycle setting program 12A determines whether the status is set (SP21). When the status is determined, the transmission cycle setting program 12A measures the position information by the position information measurement program 12E (SP22), and transmits the position information by the position information transmission program 12F (SP23). Thereafter, the transmission cycle setting program 12A sets (resets) the value of the transmission counter held by the position information transmission determination program 12D to 0 (SP24), refers to the transmission cycle data table T2, and sets the transmission cycle corresponding to the status. Set (SP25). If the status is not set, the transmission cycle setting program 12A ends the process.

  FIG. 6 shows a flowchart of the emergency response setting process (SP30). The position information transmission determination program 12D determines whether a report of confinement site information or the like has been received from the monitoring server 32 by the site information reception program 12G (SP31). Note that the position information transmission determination program 12D acquires the position information and the like of the site 50 by reporting the received confinement site information and the like.

  If the determination at step SP31 is affirmative, the position information transmission determination program 12D determines whether the status is “moving” (SP32). If the determination at step SP32 is affirmative, the position information transmission determination program 12D reports the confinement site information and the like. Whether it is within a certain range of the transmitted site 50 is determined based on the location information measured by the location information measurement program 12E and the location information of the site 50 acquired in step SP31 (SP33), and the determination in step SP33 is a positive result In this case, the status is set to “emergency” (SP34), the transmission cycle data table T2 is referred to, and the transmission cycle corresponding to the status is set (SP35). The position information transmission determination program 12D ends the process when the determinations in steps SP31 to SP33 are negative.

  In step SP33, the position information measured in step SP22 is used. However, in step SP33, the position information transmission determination program 12D may measure the position information by the position information measurement program 12E.

  FIG. 7 shows a flowchart of the position information transmission determination process (SP40). The position information transmission determination program 12D adds 1 to the transmission counter (increment) (SP41), and determines whether the value of the transmission counter is equal to or larger than the transmission cycle value set in step SP25 (SP42). When the value of the transmission counter is equal to or greater than the value of the transmission cycle described above, the position information transmission determination program 12D measures the position information by the position information measurement program 12E (SP43) and transmits the position information by the position information transmission program 12F ( (SP44), the value of the transmission counter is set to 0 (reset) (SP45). If the value of the transmission counter is smaller than the value of the transmission cycle described above, the position information transmission determination program 12D ends the process.

  Further, as shown in FIG. 8, instead of the emergency response process (SP30), a series of processes (SP31, SP33 and SP34) for setting the status to “emergency” may be performed after the process of step SP12.

(3) Processing in Monitoring Center FIG. 9 shows a flowchart of processing in the image display determination device 32C of the monitoring server 32 installed in the monitoring center 30. The image display determination device 32C determines whether a notification such as confinement is received from the remote monitoring device 50D at the site 50 (SP51). If the determination in step SP51 is affirmative, the image display determination device 32C refers to the location information on the site 50 and the maintenance personnel 15 on the location information display device 31B to determine whether there is a maintenance worker within a certain range of the site 50. Determination (SP52) is made. If the determination in step SP52 is affirmative, the image display determination device 32C acquires image data from the position information display device 31B (SP53), and transmits the image data to the site 50 via the data transmission device 32B ( SP54), it is determined whether or not confinement has been restored (SP55). Whether the confinement or the like has been recovered is determined by receiving a recovery notification from the site 50. If the determination in step SP55 is a negative result, the process returns to step SP52, and if the determination in step SP51 is a negative result or if the determination result in step SP55 is a positive result, the image display determination device 32C ends the process. . Note that the processing shown in FIG. 9 is periodically executed by processing such as timer interruption, and the processing of step SP52 to step SP55 may also be periodically executed by timer interruption or the like. And

  FIG. 10 shows a sequence diagram of the maintenance staff position information management system 1 in normal time and emergency (SP60). As shown in FIG. 10, at the normal time, the position information transmitted from the mobile terminal 10 to the position information management server 31 is an interval between the position information transmission step SP61A and the position information transmission step SP61B. If the worker is moving, it is transmitted every 10 minutes, and if it is working, it is transmitted every 60 minutes) (SP61).

  On the other hand, in an emergency, a report such as confinement is transmitted from the remote monitoring device 50D to the monitoring server 32 (SP62). Upon receipt of the notification of the confinement or the like, based on this, the monitoring server 32 transmits a report of the confinement site information or the like to the mobile terminal 10 (SP63). Upon receipt of the notification of the confinement site information, etc., the mobile terminal 10 transmits the location information to the location information management server 31 based on this notification, as an emergency such as the interval between the location information transmission step SP64A and the location information transmission step SP64B. Transmit at time intervals (SP64). This interval is, for example, 1 minute. Further, the monitoring server 32 determines whether the equipment 50C provided with the remote monitoring device 50D is a model that supports display of image data (SP68), and if it is a model that supports display, Image data is requested from the position information management server 31 (SP65), and the position information management server 31 transmits the image data to the monitoring server 32 in response to this (SP66). The monitoring server 32 transmits the image data to the remote monitoring device 50D based on the received image data (SP67).

  FIG. 11 shows image data 60 displayed on the display device 50B of the facility 50C. The image data 60 includes a map area 61 in which a map is displayed, a field information area 62 in which information on the field 50 requiring urgent response is displayed, and a maintenance staff information area 63 in which information on the maintenance staff 15 is displayed. Consists of The image data may be the same as the image data displayed on the PC 41.

(4) Effects of this Embodiment As described above, in the maintenance staff position information management system 1 according to this embodiment, the period for transmitting the position information in the portable terminal 10 to the monitoring center is increased during work with little movement. The frequency of the location information transmission is lowered, and the consumption of the battery of the mobile terminal 10 consumed by transmitting the location information is suppressed. In addition, in an emergency, the monitoring server 32 determines whether the equipment C50 is a model that can display image data. If the equipment is a displayable model, the monitoring server 32 transmits a report such as confinement site information to the mobile terminal 10. As a result, the mobile terminal 10 transmits the position information to the position information management server in a short cycle, and the position information management server sends the image data updated at intervals that allow the maintenance staff 15 to approach the monitoring center. Through the remote monitoring device 50D and displaying on the display device 50B, the user's anxiety of the facility 50C can be reduced.
