Description

  The present invention relates to a method and apparatus for managing field work by acquiring position information of a mobile terminal.

  As a conventional system for managing field work, for example, there is a power management system for electric railways. Here, when some work is required in the on-site railway facilities, a work plan is created in advance and the work schedule is registered in the power management system. In addition, when actually performing work at the scheduled date and time, the worker communicates that the work is started or finished by operating the telephone or the portable terminal.

  In such field work, the highest priority is given to ensuring the safety of the worker during the period from the start to the end of the work. For example, in the case of an electric power management system for electric railways, the electric railway power supply in the work site is shut off before starting work, the work is performed after it is in an inactive state, and the work is restored to the live state after completion. There is a need. Also, the work is often a late-night work after the vehicle stops, and it is required to finish the work within a predetermined time.

  Such on-site safety assurance and process time limit management are left to the on-site manager, but the burden on the manager is large, and it is desirable that the central power management system can grasp this.

  In this regard, Patent Document 1 receives position information transmitted from an operator, identifies the worker position on a specific map from the position information, and stores changes over time of the worker. According to the literature 1, it is possible to grasp the position of the worker along with the change of time.

Schematic which shows the database of equipment data and accumulation | storage data. The processing flow figure which put together the flow of the rough process of this invention. FIG. 5 is a processing flowchart showing details of the processing unit 2D of FIG.

  An embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram showing the configuration of a management system according to the present invention and a work site. In this figure, the central device and the work site are shown roughly.

  In the example of the figure, an example in which a power management system 2 for electric railway is installed as a central device is shown. In addition, a work plan input means 1 as an input means, a terminal communication device 4 that communicates with a worker at the time of work, and a position information acquisition device 3 that acquires worker position information at the time of work are provided.

  On the other hand, in the case of electric railways on the site side, there are facilities A, B, and C along the track 8, and the current site work is performed in the work area 10 centering on the facility B. In the present invention, the area 9 close to the work area 10 is defined as a monitoring area, and the entry and exit of the worker to the work area 10 is based on the passing of the monitoring area 9 as a rule. Each worker 5 has a portable terminal 6.

  The main composition of the center and the site is as described above. In the present invention, a plurality of databases 2A, 2B, and 2E are provided in the power management system 2 when performing on-site work management. Among these, 2A is a work database for storing work plans for field work, and FIG. 2 shows a detailed example. 2B is an equipment database that stores equipment information related to on-site equipment A, B, and C. FIG. 3 shows a detailed example. 2E is a storage database that stores data of field work planned and executed in the past and data of current work. In the power management system 2, 2D is a processing unit that processes these data, and 2C is a monitor that displays the progress of work.

  The position information acquisition device 3 also includes a database 3A. Here, position information from a portable terminal carried by each worker is stored as position data. A detailed example of the position data is shown in FIG.

  The work management procedure according to the present invention will be described below. First, at the work planning stage, the work planner M1 inputs a work schedule to the power management system 2 using the work plan input means 1. As specific input contents of the work schedule, items described in the work database 2A shown in detail in FIG. 2 are input. These are the work name, work place, worker name, number of workers, worker role, skill, ID of the portable terminal possessed by the worker, work date, work start time, work end time, and the like.

  FIG. 2 shows an example of these input items. This example is a midnight work by three workers M2, M3, and M4 in the area 10 around the facility B. The input of these series of input items does not have to be determined simultaneously by a single planner, but the determination items may be sequentially input according to the plan development status and determined by a predetermined time limit. However, when the three workers M2, M3, and M4 are determined, the IDs (XXX, YYY, and ZZZ) of the portable terminals possessed when these three workers perform work need to be input in association with each other. .

  In the database 2B of FIG. 3, the facility ID, the monitoring area position information, and the work area position information are stored in association with each other. For example, when the content of the item “work place” described in the work database 2A is equipment B, referring to “equipment ID” in the database 2B in FIG. The coordinate information meaning the area 10 is searched as the work area position information. As described above, when the items described in the work database 2A are input and the work place is determined, the database 2B in FIG. 3 is referred to correspondingly.

  Items determined by the work plan input (items described in the work database 2A) and items derived therefrom (items described in the facility database 2B) are assigned to three workers M2, M3, and M4. It is conveyed and can be started at the scheduled time on the day of the work. The IDs of the portable terminals possessed when these three persons work are XXX, YYY, and ZZZ, respectively.

  These three persons gather in the area 9 (monitoring area 9) described in the monitoring area position information of the database 2B at the scheduled time of the work day, and put the portable terminal 6 possessed into an operating state. Thereby, the position specifying information where the workers M2, M3, and M4 are located is transmitted to the terminal communication device 4 of the position information acquisition device 3. Thereafter, the position information is stored in the position database 3A, so that the position information of the mobile terminal 6 is constantly monitored.

  At this time, the information stored in the position database 3A in FIG. 2 is the terminal ID, the terminal position information, and the time. Among these, XXX, YYY, and ZZZ, which are the IDs of the mobile terminals of the three workers M2, M3, and M4, are detected as the terminal ID, and the monitoring area 9 is detected as the terminal position information.

  The work data 2A and the position data 3A in FIG. 2 and the equipment data in FIG. 3 hold the planned value and the actual measurement value as time passes, but these databases are linked to each other. Therefore, in the processing unit 2D of FIG. 1, it can be detected that the field work has started as scheduled, and can be displayed and monitored on the monitor 2C. In addition, the key of the link between specific databases is the terminal ID between 3A and 2A, the terminal ID of the worker, the terminal position information and the work place (also linked to the equipment ID of 2B), the time and the work start, For example, the end time.

  Accordingly, when XXX, YYY, and ZZZ are detected as terminal IDs in the position database 3A, the three workers M2, M3, and M4 can be identified by using the terminal IDs of the workers in the work database 2A, and the terminal position information When the time is detected, the work data 2A and the equipment ID of the equipment database 2B are also linked so that it can be understood that the user has entered the monitoring area 9 before the work of the equipment B (area 10).

  In this manner, when the worker 5 enters the point of the monitoring area 9 designated at the time of inputting the work schedule for the work, the work progress status automatically becomes the work preparation start status. The position data 3A stored at this time is collated with the work data 2A and the facility data 2B. When the data match is confirmed and the process is correctly completed, a confirmation request to the mobile terminal 6 confirms with the worker 5 (the central side confirms that the scheduled personnel have entered the monitoring area for the scheduled work) Contact).

  Then, work starts from the center side to the equipment B by automatic processing. For example, energization from the power source for the railway to the work area 10 is stopped, and an operation for ensuring safety in the work area 10 is executed from the center side. The operator enters the work area 10 for the first time after confirming that the electric railway power supply is turned off at the portable terminal 6 and starts a predetermined facility maintenance work.

  In this way, the meaning of confirming the location where workers gather in the monitoring area is to confirm that all workers are present at a position away from the work area, and to ensure safety in the work area. Is to execute from the center. Even when withdrawing from the work area, the location of the worker is confirmed in the monitoring area and the power is turned on. In the present invention, by adopting such a countermeasure, the safety of the site is achieved while reducing the burden on the manager.

  Next, the management of the progress status during work will be described. The work status is output to the monitor 2C as the work progress status. Even during this work period, the position information of each worker is grasped by the position information acquisition device 3 on the center side based on the position information using the portable terminal. For the work progress management during this work period, reference is made to the storage database 2E of FIG.

  The data items of the accumulated data 2E include work type, action pattern, movement distance per unit time, movement pattern per unit time, positional relationship with the worker per unit time, positional relationship with the equipment per unit time, etc. is there.

  These data items of the accumulated data 2E are obtained by accumulating actual values at the same kind of work performed in the past. By comparing and displaying the current work and the past work on the monitor 2C, within the scheduled time The progress of work to be completed can be grasped to some extent even at the center. For example, regarding the painting work performed by the worker M3 in the work database 2A, this time, when the painting at a distance of 30 meters is scheduled to be completed, the actual value at the time of the painting work in the past case is compared to the scheduled end time. It is possible to grasp that work can be completed.

  As described above, in the present invention, the progress of the current work can be grasped in the center by comparison with the past results of the same kind of work.

  In this way, when the work in the work area 10 is completed, the data collation process of the position data 3A is performed when entering the point of the monitoring area 9 designated at the time of the work schedule input. Thereby, it can be confirmed that the scheduled worker has finished the work in the work area 10 at the work end time and has returned to the monitoring area 9. When this is confirmed on the central side, the data match is confirmed, and when the processing is correctly completed, the operation is terminated by automatic processing, electric power is turned on in the track 8, and the worker is instructed to leave.

  FIG. 4 is a processing flow diagram summarizing the general processing flow of the present invention. Here, the position data 3A is received from the portable terminal 6 in step S42. The processing unit 2D performs processing using the position data 3A. The work status is displayed on the monitor 2C as work progress information. Work progress information serving as a comparison reference is output from the accumulated data 2E.

  FIG. 5 is a processing flow diagram showing in detail the processing in the processing unit 2D of FIG. At this stage, the work plan has been completed, and workers have gathered in the monitoring area 9 to perform actual work. First, when the worker 5 enters the monitoring area 9, the portable terminal 6 is brought into a communicable state, so that the position information acquisition device 3 obtains position data.

  In the processing in the processing unit 2D in such a state, data collation processing is performed in steps S51 to S53 based on the acquired information of the position database 3A.

  First, in step S51, the terminal ID information in the position database 3A is compared with the terminal ID information of the worker in the work database 2A. In step S51, it is checked that the two match, and it is confirmed that the worker is registered in the work database 2A. For example, when XXX, YYY, and ZZZ are detected as terminal ID information in the position database 3A, if the same is stored as the worker terminal ID in the work database 2A, the process proceeds to the next step S52.

  When the ID is different from the scheduled one, there is a possibility that an unscheduled worker has been mixed in, and a confirmation request process is executed in step S56. For example, a field worker is called by a portable terminal to check the circumstances. If it is considered illegal, an alarm process or the like in step S59 is further performed.

  In the next step S52, the terminal position information of the position data 3A is compared with the work place information of the work data 2A. In step S52, it is checked that the two match, and it is confirmed that the work place registered in the work database 2A has been reached. For example, the area 9 is initially recognized as the terminal location information in the location database 3A. At this time, as the work place information in the work database 2A, the work area 10 is registered, and there is no information on the area 9, so there is a mismatch. However, by obtaining information by referring to the equipment ID in the equipment database 2B in FIG. 3, the area 9 recognized as the terminal location information in the position database 3A is actually the monitoring area before entering the work area 10. Make sure. As a result of the follow-up survey up to the equipment database 2B, when a match is confirmed, the process proceeds to the next step S53.

  If the result of the follow-up survey is different from the planned location, there is a possibility that the operator has visited an unscheduled work location due to misunderstanding of the worker, etc., and a confirmation request process is executed in step S56. For example, a field worker is called by a portable terminal to check the circumstances. If it is considered illegal, an alarm process or the like in step S59 is further performed.

  In the present invention, for safety measures, the worker is not allowed to enter the work area directly, but is always via the monitoring area. For this reason, in the process of step S52, when the terminal position information of the position data 3A and the work location information of the work database 2A are compared, they should not coincide at this stage. As a result of further follow-up investigation, the equipment ID in the equipment database 2B should be referred to match the information registered in the monitoring area position information. If it matches the work location information in the work database 2A, it is necessary to execute a confirmation request process in step S56.

  In the third step S53, the time information in the position database 3A is compared with the work start time and work end time in the work database 2A in order to check that the work is performed according to the registered time. It is confirmed that the work time is included within the error range specified by the work start time to the work end time. When these conditions cannot be satisfied, a confirmation request process 56 is performed on the mobile terminal 6. Subsequently, an alarm output process 59 can be performed to notify the operator 5 not to perform an incorrect operation.

  When the conditions of Step S51, Step S52, and Step S53 are satisfied, the next step S54 checks whether the worker 5 has passed the point designated when inputting the work schedule in the monitoring area 9. If not, wait for it to pass.

  In step S55, the number of times of passage through a certain point in the monitored worker monitoring area 9 is confirmed. If it is the first entry, a confirmation request process is executed using a portable terminal in step S56. The confirmation content in this case is to enter the work area and start work from now on. After confirmation, the “work start” automatic processing (electric power supply shutdown) in step S57 is executed, and the worker is allowed to enter. To do.

  The processing flow of FIG. 5 performs the above determination when the worker enters the work area 10. Also, when the worker finishes the work in the work area 10 and returns to a point in the monitoring area 9, the flow of FIG.

  Since the flow at the time of leaving is the same as described above from step S51 to S55, this is omitted. However, in step S55, the number of times of passage of a certain point in the monitored area 9 of the confirmed worker is confirmed, and it is determined that it is not the first.

  If it is not the first entry, the confirmation request process is executed using the portable terminal in step S56. The confirmation content in this case is to finish the work in the work area 10 and leave, and after the confirmation, the “work end” automatic processing (turning on the electric railway power supply) in step S58 is executed to leave the worker. Allow.

  In FIG. 4, when the current position data is received (step S42) and the passage of the monitoring area is not confirmed, the processing of the processing unit 2D is terminated, and the process proceeds to the work progress status display 2C. .

  According to the present invention described above, automatic processing is performed by acquiring position information from a portable terminal using a position specifying function such as GPS and collating data. In addition, the progress can be managed according to the work progress status, and the state of the equipment can be known from the operator by inquiry. This makes it possible to improve work management and ensure worker safety.

  In Patent Document 1, the worker's position is monitored over time to detect the worker's dynamics. In other words, while focusing on the movement of the worker, the present invention aims to manage the progress of the entire work by collating operation patterns according to the positions of workers, equipment, work schedules, and work types.

  According to the method of the present invention configured as described above, the progress of work can be automatically managed by the position and action pattern for each role of the worker. If the meeting place for the pre-work meeting does not come within the designated time, the position of the worker in charge can be confirmed and a confirmation can be communicated, or an alarm can be output if the work area is entered before the work time. Similarly, it is possible to turn on the power after confirming that the worker has evacuated from the work area upon receiving notification of the work completion. In this way, safer and more efficient work is possible.

  Also, by storing the skill information of the workers in the database, in the event of an emergency, it is possible to assign workers with the necessary skills near the location. Prompt response in an emergency can minimize damage. The trend of workers during work has been grasped, and the option of automatic contact has been increased in the traditional manual contact method. Also, by accumulating behavior patterns, work progress is automatically acquired. By managing from both human and system aspects, it is possible to contribute to labor saving and to work more safely.

  The present invention can be applied to management in many field operations other than for electric railways.
