According to such a configuration, the first maintenance mobile body performing the work recognizes the scheduled time when the second maintenance mobile body having the necessary equipment reaches the place where the maintenance work of the equipment is performed. The maintenance work can be started as much as possible by using the equipment of the first maintenance mobile body itself until the scheduled arrival time of the second maintenance mobile body. Thus, it is possible to further ensure the speed of maintenance work.

  In the present invention, “equipment” refers to parts, fixtures, tools, instruments, and the like necessary for maintenance (such as repair and maintenance). Further, in the present invention, the “equipment installation location” used in the “maintenance mobile body searching means” means a location where the equipment is installed. Note that the installation location itself may use a name that identifies the device. Further, in the present invention, “maintenance mobile terminal” refers to a mobile terminal that can be installed in a person or vehicle that can be moved to a predetermined location for maintenance, such as a maintenance worker or a maintenance vehicle for repair. In the present invention, the “working status” indicates a state of maintenance, movement, or standby.

  In the present invention, the transmission means displays information on a display screen of a computer, or transmits information to a maintenance mobile terminal included in a corresponding maintenance person or maintenance vehicle.

  Further, in the present invention, the “maintenance movable body” is a vehicle that can be moved to a place where maintenance is performed, such as a vehicle for maintenance work or a maintenance worker, and can perform maintenance. In the present invention, the “reception unit” may receive information data transmitted from the device, or may receive information data transmitted by the administrator of the device.

  The technical idea of the present invention is not necessarily limited to the above-described combination, and includes a technical idea realized by arbitrarily combining any of the above-described plurality of inventions.

  According to the maintenance management device and the maintenance management method of the present invention, when a failure occurs in a device, the first maintenance moving body closest to the installation location of this device is moved in advance, and the possessed equipment is insufficient. If the second maintenance mobile unit is made to replenish the shortage of equipment, the location of the faulty device can be reached as soon as possible.

  The timer 5 is configured to have a timekeeping function, and is configured to be able to measure the time between the current time and a predetermined time to another predetermined time. Further, regarding the timing process by the timer 5, the calculation process by the control unit 2 is executed, so that a time after a predetermined time has elapsed from a certain time can be calculated.

  The communication unit 6 is configured to be able to read traffic information data by communicating with a host computer (not shown) of the traffic information center 40 provided outside. In addition, the communication unit 6 is configured to be able to communicate with the maintenance mobile terminal 20 configured to be portable for maintenance personnel and the device 30 that needs to perform maintenance management.

  In addition, the auxiliary storage unit 7 stores storage areas of a possessed equipment storage unit 8, an equipment storage unit 9, a maintenance worker information storage unit 10, and a failure information storage unit 11.

  The possessed equipment storage unit 8 is a matrix-like possession in which information data including a maintenance staff's unique number (maintenance staff number), the possessed equipment for each maintenance staff and the number of possessions is sequentially stored for each maintenance staff. The equipment data table is stored. An example of the possessed equipment data table stored in the possessed equipment storage unit 8 is shown in FIG.

  As shown in FIG. 2, in this embodiment, specifically, the maintenance equipment numbers 001 to 005 are assigned and stored for each maintenance staff in the possessed equipment storage database. Further, in this possessed equipment data table, tools and parts possessed by the respective maintenance personnel, that is, possessed equipment types are stored as data of six types (tool 1 to tool 3 and parts 1 to part 3). The number of possessed equipment is stored and stored in a matrix in association with the maintenance staff number data.

  More specifically, for example, in the case of a maintenance person whose maintenance person number is “001”, each of the tools 1 to 3 is possessed, and one part 1 and four parts 3 are possessed. The component 2 is stored as a state where it is not possessed.

  In addition, each possession value in this possessed equipment data table decreases when maintenance personnel use equipment such as replacement parts in maintenance work of various devices, and increases when replenished. Or This information changes every moment based on data transmitted from the maintenance mobile terminal carried by the maintenance personnel, and in this possessed equipment data table, information on equipment possessed by the maintenance staff can always be updated. It has become.

  Further, the equipment storage unit 9 is classified according to the type of failure that occurs in the device in which the failure occurs, and data of equipment (for example, tools and parts) required for each type of failure, and the type of failure. Data such as the quantity of equipment required for each is stored and stored in a matrix form as an equipment data table. An example of the equipment data table stored in the equipment storage unit 9 is shown in FIG.

  As shown in FIG. 3, in the equipment data table according to this embodiment, data relating to four types of failures assigned with type numbers 001 to 004 are stored as types of failures.

  Then, sufficient equipment for each type of failure, for example, three types of tools and three types of parts, are stored and stored as six types of equipment data in total. Data on the number of equipment required in association with the fault type number is stored and stored in a matrix.

  More specifically, for example, when a failure with a failure type number “004” occurs, the equipment necessary for the maintenance work is one for each of the tool 1 and the tool 2, two for the component 2, Information that there are two parts 3 is stored. The necessary equipment corresponding to the type of failure and the number thereof are known information that is fixed in advance for each type of failure. In this embodiment, the equipment is stored in the equipment storage unit 9. The equipment data table is fixed and basically unchanged.

  The maintenance staff information storage unit 10 also includes maintenance staff number data, current position data for each maintenance staff, work status data indicating whether the maintenance staff is performing maintenance work, and maintenance staff execution. The maintenance work type data and the scheduled work end time data are associated with each other and stored as a maintenance staff information data table. An example of the maintenance staff information data table stored in the maintenance staff information storage unit 10 is shown in FIG.

  As shown in FIG. 4, in this embodiment, specifically, the maintenance staff information data table stores current status data regarding five maintenance staff assigned with maintenance staff numbers 001 to 005 respectively. ing.

  The maintenance staff information data table stores the current status of each maintenance staff as status information data that can be recognized by the control unit 2. More specifically, for example, in the case of a maintenance person whose maintenance person number is “001”, the maintenance person has the current position (200, 200), the working state “working”, the type of work (failure) Is stored in the state information data indicating that the vehicle traffic signal lamp has run out and the scheduled time at which this maintenance operation is to be completed is “15:00”.

  In addition, the numerical value of the current position in the maintenance worker information data table is a position where the maintenance target device exists when the maintenance worker is working (working state: “working”). Further, when the maintenance staff moves on a vehicle or the like, the current position changes one by one. In addition, the maintenance staff whose work state is on standby can be dispatched when a failure occurs.

  The maintenance staff information is information that changes every moment based on data transmitted from the maintenance mobile terminal 20 carried by the maintenance staff. In the maintenance staff information data table, the status information of the maintenance staff is constantly updated.

The failure information storage unit 11 includes failure occurrence number data added by the control unit 2 according to the failure occurrence order, failure occurrence time data, failure device name data, failure type data including failure number data, The device installation location data and the device installation location name data are associated with each other and stored as a failure information data table. An example of the failure information data table stored in the failure information storage unit 11 is shown in FIG.

  As shown in FIG. 5, in this embodiment, specifically, in the failure information data table, for example, three failures are associated with failure numbers 001 to 003 assigned by the control unit 2 in the order of occurrence. Status data relating to occurrence is stored.

  This failure information data table is stored as failure information data that allows the controller 2 to recognize the failure status. More specifically, for example, in the case of the failure with the failure number “002”, the device in which the failure has occurred is a traffic signal for a vehicle, the installation location is (300, 650), and the location name is “ DEF intersection ". Then, the time when the failure occurred in this vehicle traffic signal is 14:00, and the type of the failure is “inclination of the vehicle traffic signal”. In this embodiment, “the inclination of the vehicle traffic signal” corresponds to the type number “002” as the type of failure.

  In addition, this failure occurrence information data table is a data table in which the data itself increases or decreases with the occurrence of a failure or the repair of a failure so that the status information is constantly updated according to the occurrence or repair of a failure. It has become. These item data are not necessarily limited to the items shown in FIG. 5. Other item data may be included, or item data such as device installation location name data and faulty device name data may be omitted. It is also possible to do.

  The respective data tables in the possessed equipment storage unit 8, the equipment storage unit 9, the maintenance staff information storage unit 10, and the failure information storage unit 11 are stored in a predetermined area of the auxiliary storage unit 7. The unit 2 is configured to be searchable.

  The maintenance management device 1 described above can be communicated with the maintenance mobile terminal 20, the equipment 30, and the traffic information center 40 carried by maintenance personnel through the communication unit 6 via the communication networks 21, 31, and 41, respectively. Thus, a maintenance management system according to this embodiment is configured.

(Maintenance management method)
Next, a maintenance management method using the maintenance management apparatus 1 according to this embodiment configured as described above will be described. FIG. 6 shows a flowchart of the maintenance management method according to this embodiment, and FIG. 7 shows the current position of each maintenance staff and the location of occurrence of each failure in an example of the maintenance management method according to this embodiment.

  That is, as shown in FIG. 6, first, when a failure occurs in the device 30, a failure occurrence signal indicating the occurrence of the failure is output from the device 30 and transmitted. The output failure occurrence signal is received by the communication unit 6 as failure information receiving means via the communication network 31.

  In the maintenance management device 1, the device setting location data and the failure information data included in the failure occurrence signal are extracted by the control unit 2, and the failure number data is added and stored in the failure information storage unit 11.

  In this embodiment, as an example, when a failure such as a lamp failure occurs in a vehicle traffic signal at the GHI intersection at 15:00, for example, as shown in FIG. ”Is added and sequentially stored in the failure information data table of the failure information storage unit 11.

  Thus, in step ST1, installation location data and failure information data of the device 30 are received (step ST1). The failure occurrence signal may be transmitted from the administrator of the device 30 in addition to adopting a method of outputting from the device 30.

  Next, the process proceeds to step ST2, and maintenance staff information data including the current position and work status of each maintenance staff is output and transmitted from the maintenance mobile terminal 20 carried by each maintenance staff. The output maintenance worker information data is received by the communication unit 6 as a receiving means via the communication network 21.

  In the maintenance management device 1, the current position data and work state data included in the maintenance staff information data are extracted by the control section 2 and stored in the maintenance staff information storage section 10. At this stage, the item data changed in the failure information storage unit 11 is at least current position data and work state data as shown in FIG. If necessary, the work type data and the work end scheduled time data may be changed as needed. Further, the item data is not necessarily limited to the item data shown in FIG. 4, and other item data may be included, or work type data may be omitted.

  Next, the process proceeds to step ST3, where the control unit 2 of the maintenance management apparatus 1 stores the device installation location data in the failure information data table stored in the failure information storage unit 11 and the maintenance staff information storage unit 10. Current position data and work status data are retrieved.

  That is, first, work state data is searched, and maintenance personnel whose work state data is “standby (standby state)” are searched. In this embodiment, maintenance personnel whose maintenance personnel numbers are “003” to “005” are searched for as maintenance personnel whose work status data is “standby”.

  Next, the control unit 2 uses the current installation position data (“600, 200”) of the current position data of the waiting maintenance personnel (003 to 005) and the failure information data (“003”) where the failure has occurred. )). Then, as shown in FIG. 7, the maintenance staff closest to the device installation location data is searched as the first maintenance staff from the maintenance staff information data whose work state is “standby”. Here, the maintenance person with the maintenance person number “003” becomes the first maintenance person.

  Next, the process proceeds to step ST4 shown in FIG. 6, and the communication unit 6 receives the traffic information data output from the traffic information center 40 to the communication network 41. Thereafter, accident information data, traffic jam information data, and the like are supplied by the traffic information data received by the communication unit 6.

  Then, based on the received traffic information data, the control unit 2 and the timer 5 calculate the time until the maintenance staff closest to the failed device 30 reaches the device 30. Here, the required travel time from the current position (“500, 300”) of the maintenance staff number “003” to the installation location (“600, 200”) of the failed device is calculated.

  Then, the scheduled time (scheduled arrival time) at which the first maintenance staff “003” arrives at the installation location of the failed device is calculated based on the travel time and the current time that is always kept by the timer 5. The

  Thereafter, the process proceeds to step ST6, where a necessary equipment search process is executed. That is, first, failure type data in the failure information data stored in the failure information storage unit 11 is retrieved by the control unit 2. In this case, the lamp traffic outage “003” of the vehicle traffic signal is searched.

  Subsequently, the control unit 2 searches the equipment data table stored in the equipment storage unit 9 based on the retrieved failure type data (see FIG. 3). Here, the fault type number “003” is searched as the fault type in the fault information data. When the controller 2 searches the equipment data table for data of the corresponding failure type “003”, the necessary equipment information included in this data is read. Here, as the necessary equipment information, data of one “tool 3” and two “component 3” is read.

  Next, the process proceeds to step ST7, where the control unit 2 transmits an outgoing command signal to the maintenance mobile terminal 20 through the communication unit 6 through the communication circuit 21. Here, the dispatch command signal includes fault information data and work place data in the equipment storage unit 9, and the fault information and fault are displayed on a display screen (not shown) provided in the maintenance mobile terminal 20. The data of the location (working location) of the occurrence is displayed.

  Thereafter, the process proceeds to step ST8, where the control unit 2 determines whether the first maintenance staff has equipment necessary for maintenance of the failed device, that is, possesses equipment capable of solving the failure. Judgment is made.

  That is, the control unit 2 first reads out the necessary equipment type data corresponding to the type of failure, and searches the possessed equipment data table stored in the possessed equipment storage unit 8. Then, the controller 2 compares the read equipment type data with the possessed equipment data. Specifically, in this embodiment, the equipment required for maintenance is one “tool 3” and two “parts 3” (see FIG. 3), while the equipment possessed by the first maintenance person “003”. Are 0 “tool 3” and 2 “component 3” (see FIG. 2).

  As a result of this determination processing, if the equipment possessed by the first maintenance staff is sufficient for maintenance (repair) of the failed device, the first maintenance staff performs the same as in the normal maintenance processing. Maintenance personnel move to the location of the failure and perform maintenance work. Thereby, maintenance management is completed.

  On the other hand, as a result of the determination processing, if the equipment possessed by the searched first maintenance staff does not have equipment necessary for maintenance of the equipment in which the failure has occurred, the process proceeds to step ST9 to generate the failure. The second maintenance staff search process is carried out that can possess or possess equipment that is necessary for maintenance of the equipment that the first maintenance staff does not have (hereinafter, lack equipment).

(Second maintenance personnel search process)
Here, a specific example of the second maintenance worker search process will be described with reference to two examples.

(First method of second maintenance worker search processing)
First, the second maintenance worker search process according to this embodiment will be described. FIG. 8 shows an example of a flowchart of the second maintenance staff search process according to this embodiment.

  As shown in FIG. 8, in the above-described step ST8 (see FIG. 6), when the first maintenance person “003” does not have the equipment necessary for the maintenance of the failure, first, in step S1, the control unit 2 Thus, it is determined whether all waiting maintenance personnel other than the first maintenance personnel have been searched.

  If the search for all the maintenance personnel on standby is not completed, the process proceeds to step S2. Then, in the same manner as in the above-described step ST3, the control unit 2 searches the maintenance worker information storage unit 10 for a maintenance worker at a position close to the location of the failure and on standby.

  Thereafter, when a maintenance person is searched, the process proceeds to step S3, and the possessed equipment data table stored in the owned equipment storage unit 8 read by the control unit 2 is searched, and the owned equipment data relating to the searched maintenance staff is retrieved. Is read out.

  Subsequently, the process proceeds to step S4, and the control unit 2 determines whether or not the first maintenance staff possesses insufficient equipment with respect to the possessed equipment data read by the second maintenance staff. If the searched maintenance person possesses the lack of equipment of the first maintenance person, the searched maintenance person becomes the second maintenance person, and the second maintenance person search process ends. To do.

  On the other hand, if the searched maintenance person does not have the lack of equipment of the first maintenance person, the process proceeds to step S1 and the above-described steps S1 to S3 are repeatedly executed.

  Then, when the search process is repeatedly executed and all maintenance personnel waiting in step S1 are searched, that is, the working state is “waiting” and the first maintenance personnel has insufficient equipment. If there is no maintenance staff, the process proceeds to step S5.

  In step S5, the control unit 2 searches for the maintenance staff whose work status data is “standby” and whose current position is closest to the place where the equipment is stored (equipment storage place). Supplied as maintenance personnel.

  Then, the process proceeds to step S <b> 6, and the control unit 2 transmits the shortage equipment information data of the first maintenance staff to the maintenance mobile terminal 20 of the second maintenance staff. The insufficient equipment information data is displayed on a display unit (not shown) provided in the maintenance mobile terminal 20. As a result, the second maintenance staff can recognize the equipment required by the first maintenance staff.

  Thus, the second maintenance staff search process ends. Then, the second maintenance staff carries out necessary equipment from the equipment storage location based on the displayed insufficient equipment information. As a result, the second maintenance staff possessing the lack of equipment of the first maintenance staff is searched.

(Second method of second maintenance personnel search process)
Another example of the second maintenance staff search process according to this embodiment will be described. FIG. 9 shows a flowchart of the second maintenance staff search process according to the second method.

  In the second maintenance worker search process, the process is started by moving to step ST9 following step ST8 in the maintenance management method described above. Then, as shown in FIG. 9, in step S11, a maintenance person whose work status data is “standby” and whose current position data is closest to the equipment storage location is searched.

  Next, the process proceeds to step S12, and it is determined whether or not the searched maintenance staff possesses the lacking equipment of the first maintenance staff.

  As a result of the determination, if the searched maintenance person possesses the lack of equipment of the first maintenance person, the searched maintenance person is set as the second maintenance person, and the second maintenance person search is performed. The process ends. Thereafter, the process proceeds to step ST10 in the maintenance management method.

  On the other hand, in step S12, when the searched maintenance person does not have the lack of equipment of the first maintenance person, the process proceeds to step S13, from the control unit 2 via the communication unit 6 and the communication circuit network 21, The information data of the lacking equipment of the first maintenance staff is transmitted to the maintenance mobile terminal 20 of the found maintenance staff. As a result, the searched maintenance staff can recognize the necessary equipment, so that the missing equipment can be replenished by visiting the equipment storage place.

  In step S12, when it is determined that the searched maintenance staff possesses the lack of equipment of the first maintenance staff, this maintenance staff is designated as the second maintenance staff, and the second maintenance staff search. The process ends. Thereafter, the process proceeds to step ST10 of the maintenance management method.

  As described above, when the second maintenance staff possessing the insufficient equipment is searched for by the control unit 2 by various processes in step ST9, the communication unit 6 and the communication network 21 as the transmission means from the control unit 2 are searched. The delivery command signal including the work place data and the failure information data is transmitted to the maintenance mobile terminal 20 of the second maintenance person via the. If necessary, necessary equipment data can be transmitted together.

  Thereafter, the process proceeds to step ST11, and based on the traffic information data already received, the scheduled time at which the second maintenance staff arrives at the current position of the first maintenance staff is calculated in the same manner as in step ST5. The

  Thereafter, the process proceeds to step ST12, where the control unit 2 and the timer 5 change the first maintenance staff searched in step ST3 to the installation position of the equipment for which maintenance work is performed by the first maintenance staff. The time when the second maintenance staff is scheduled to arrive, that is, the estimated arrival time is transmitted. As a result, the first maintenance staff must perform maintenance work within the possible range of work even if the equipment is owned by the first maintenance staff until the second maintenance staff arrives. Can do.

  As described above, the maintenance management process according to this embodiment is executed. Actually, when the second maintenance person passes the missing equipment to the first maintenance person, the equipment necessary for the maintenance of the failed device is prepared as the equipment owned by the first maintenance person. Therefore, it becomes possible for the first maintenance staff to repair (maintain) the failed device.

  Although one embodiment of the present invention has been specifically described above, the present invention is not limited to the above-described embodiment, and various modifications based on the technical idea of the present invention are possible.

  For example, the possessed equipment type data and numerical data, maintenance staff information data, and failure information data listed in the above-described embodiment are merely specific examples in the description, and differ depending on individual specific situations. The possessed equipment type data and numerical data, maintenance staff information data, and fault information data are adopted.
