Description

  The present invention relates to a technology for push-distributing information in real time, and more particularly, a system for maintenance of facilities and equipment distributed over a wide field, such as a power / gas supply system and a road / river management system. The present invention relates to a technique suitable for distributing information to maintenance personnel.

  In general, information delivery from a server to a client performed on the Internet realizes an apparent push delivery by requesting update information according to a predetermined schedule. It looks like the information is being updated automatically.

  However, in such an apparent push distribution, there is a problem that even if the server information is updated, it is not immediately transmitted to the client depending on the setting of the update schedule.

  Therefore, a “real push” type information distribution technique has been devised in which information of new contents is immediately registered in the server and the information is immediately distributed to the client. In this method, the client reserves the type of information desired to be distributed in advance using the ASCII code, and the server reserves the type of information when new information is registered. The information is distributed. As a result, the client can automatically receive the reserved type information without inquiring of the server.

  Here, when a maintenance person moves from place to place in a mobile environment and considers a maintenance system that handles maintenance for facilities and equipment distributed over a wide field, the information required by the maintenance person is not simply represented by the information type. For example, information relating to the current position during patrol or information relating to the maintenance staff's area in charge differs depending on the state of the maintenance staff (location and business content). Also, the maintenance personnel who need the information differ depending on the location of the information to be distributed.

  That is, for example, in maintenance operations, maintenance personnel generate a failure in response to a normal operation in which inspection is performed while patroling the monitoring field, and an abnormality detection of a sensor installed in the monitoring field or a report from a customer. There is an emergency work that goes straight to the location to perform fault recovery. Of these, in the case of an emergency work, if an alarm or notification occurs, the local maintenance staff at the place where the event occurred will be visited nearby. There is also a request for maintenance information to be distributed.

  However, if the conventional real push type information distribution technology described above is applied, it is necessary to re-register the information type every time the maintenance staff moves around the district, which is troublesome and complicated to manage. End up. In addition, when carrying out emergency work, information such as construction history and past work reports on the relevant location is useful. However, when trying to distribute these to maintenance personnel using conventional technology, construction and work reports are not available. It will be delivered at the time it was made, and information that is not necessary for normal business will be delivered unconditionally.

  As described above, there are many problems that cannot be dealt with in the conventional real push type information distribution technology in the maintenance system in which the facilities and equipment distributed in the wide field are handled as maintenance.

  Therefore, the object of the present invention is to solve these problems and to provide the information in real time only to the delivery destination that needs the information in consideration of the current location of the delivery destination (maintenance staff). It is to realize a technology capable of delivering relevant information required for emergency work to maintenance personnel in a timely manner during emergency work.

  If the object of the present invention is achieved, the responsiveness and efficiency of maintenance work can be improved in a maintenance system in which facilities and equipment distributed over a wide field are handled as maintenance.

A program 30 is a mobile communication program.

  The spatial information management DB 21 stores map information, distribution facility information, resource information, and space generation information. Here, the distribution facility information is information (name, structure, position information, etc.) regarding the distribution facility (steel tower, utility pole, distribution line, etc.), and the resource information is information regarding the monitoring station 2 and the maintenance staff terminal 3 (ID, Phone number, location information, etc.). The space generation information includes observation information at the monitoring station 2, notification information from customers, work report information from the maintenance staff terminal 3, and the like, and is information generated by resources in the monitoring field.

  The information collection program 26 performs observation information collection processing, and the alarm reception program 27 receives alarm information from the monitoring station 2. The terminal message reception program 29 receives information from the maintenance staff terminal 3. The information distribution program 28 distributes the information collected by the information collection program 26 and the alarm information received by the alarm reception program 27 to the maintenance staff terminal 3 as necessary. The center screen display program 23 displays map information, facility information, resource information, and space generation information on the screen of the commander terminal 1c based on the contents of the space information management DB 21. The report reception program 24 performs registration processing for the report information received by the telephone 1c. The mobile communication program 30 realizes mobile communication with the monitoring station 2 and the maintenance staff terminal 3.

  Next, the software configuration of the monitoring station 2 (control device 2a) is shown in FIG.

  In FIG. 3, 31 is a mobile communication program, and 32 is an observation data transfer / status monitoring program.

  Finally, FIG. 4 shows the software configuration of the maintenance staff terminal 3 (pen computer 3b).

  As shown in FIG. 4, the software configuration of the maintenance staff terminal 3 includes a mobile communication program 41, a GPS location report program 42 that transmits location information of the maintenance staff terminal 3 measured by the GPS device 3a, and a navigation function 43. The terminal screen display program 44, the spatial information management DB 45, the spatial information receiving program 46 for receiving information from the monitoring center 1, and a business support program 47 for supporting maintenance personnel work are included.

  The space information management DB 45 stores map information, power distribution facility information, and space generation information transmitted from the monitoring center 1.

  Note that the hardware configuration of each device is the same as the hardware configuration of a general information processing device including a CPU, a memory, and a communication I / F.

  The operation according to the first embodiment will be described below.

  First, processing until the monitoring center 1 receives observation information and alarm information from the monitoring station 2 will be described with reference to FIGS.

  In the monitoring center 1, the information collection program 26 periodically executes the processing shown in the processing flowchart of FIG. 5, and the observation information from the monitoring station 2 (status value detected by the sensor 2c, video taken by the digital camera 2b). Information).

  That is, in the monitoring center 1, as shown in FIG. 5, the information collection program 26 first acquires the address information of all the monitoring stations 2 from the spatial information management DB 21, and stores the monitoring station address table 60 shown in FIG. Expand upward (step 501).

  As shown in FIG. 6, the monitoring station address table 60 includes IDs 61 and telephone numbers 62 of all the monitoring stations 2 in the monitoring field, and the information collection program 26 uses each monitoring station 2 based on the monitoring station address table 60. Are sequentially connected, receive an observation message, and store observation information set in the received observation message in the spatial information management DB 21 (step 502 to step 504).

  The information collection program 26 transmits the received observation message to the center screen display program 23 and the information distribution program 28 by inter-process communication (step 505), and then disconnects the line (step 506).

  After performing steps 502 to 506 for all the monitoring stations 2 (step 507), the processing is terminated.

  Here, the format of the observation message is as shown in FIG. 7, and this format is common to an alarm message, a notification message, a terminal location information message, a work report message, and a delivery condition registration message, which will be described later.

  These messages are distinguished by the setting contents of the information type 74. The ID 71 is set to the ID of the monitoring station 2 or the maintenance staff terminal 3, the position information 72 is set to the position information of the monitoring station 2 or the maintenance staff terminal 3, and the time information 73 should be notified by a message. The time when the information was acquired is set. Further, the content of information to be notified by a message is set in the data 75.

  On the other hand, in the monitoring station 2, the observation data transfer / status monitoring program 32 executes the processing flowchart shown in FIG.

  That is, in the monitoring station 2, as shown in FIG. 8, the observation data transfer / status monitoring program 32 first sets a timer (step 801) so that the timer routine is periodically started. In parallel with waiting for the observation information request from the monitoring center 1, the status of the devices such as the sensor 2c and the digital camera 2b and the status value detected by the sensor 2c are checked, and an abnormality is detected on the monitoring station 2 side. This is for detection.

  After setting the timer, the observation data transfer / status monitoring program 32 waits for line connection from the monitoring center 1, and when the line connection is made and observation information is requested (step 802), the status value detected by the sensor 2c. The video information captured by the digital camera 2b is acquired as observation information (step 803), and an observation message in which the observation information is set is created and transmitted to the monitoring center 1 (step 804).

  After the transmission of the observation message, the observation data transfer / status monitoring program 32 disconnects the line with the monitoring center 1 (step 805) and waits for a line connection from the monitoring center 1 again.

  On the other hand, when the timer routine is started, the observation data transfer / status monitoring program 32 checks the status of devices such as the sensor 2c and the digital camera 2b, and the status value detected by the sensor 2c (step 806). . If the check result is normal (step 807), the timer is set again (step 811), and the timer routine is terminated. If an abnormal check result is found (step 807), an alarm line is connected to the monitoring center 1 (step 808), and an alarm message in which status values and video information are set as alarm information is created. The data is transmitted to the monitoring center 1 (step 809).

  After transmission of the alarm message, the observation data transfer / status monitoring program 32 disconnects the alarm line with the monitoring center 1 (step 810), sets a timer (step 811), and ends the timer routine. .

  The alarm message transmitted from the monitoring station 2 by this timer routine is processed by the alarm reception program 27 in the monitoring center 1.

  FIG. 9 is a process flowchart of the alarm reception program 27.

  As shown in FIG. 9, the alarm reception program 27 is in a line connection waiting state from the monitoring station 2 (step 901), and when an alarm message is received after being connected to the line (step 902), the received alarm message is displayed. The set alarm information is stored in the spatial information management DB 21 (step 903).

  The alarm reception program 27 transmits the received alarm message to the center screen display program 23 and the information distribution program 28 by inter-process communication (step 904), and then disconnects the line (step 905). Return to the line connection waiting state again.

  Through these processes, the monitoring center 1 can periodically receive an observation message from the monitoring station 2 and can receive an alarm message when the monitoring station 2 is abnormal. Further, the message received by the monitoring center 1 is stored in the spatial information management DB 21 and transmitted to the center screen display program 23 and the information distribution program 28.

  Next, registration processing when a report from a customer or the like is received in the monitoring center 1 will be described with reference to FIG.

  When the commander of the monitoring center 1 receives a report from a customer or the like via the telephone 1c, the commander starts the report reception program 24.

  FIG. 10 is a process flowchart of the report acceptance program 24.

  As shown in FIG. 10, when the report reception program 24 first receives an input of a report location and report contents confirmed by a commander from a customer or the like (step 1001), a report message in which the received contents are set as report information is displayed. Create (step 1002).

  The report acceptance program 24 stores the report information in the spatial information management DB 21 (step 1003) and transmits the report information to the center screen display program 23 and the information distribution program 28 by inter-process communication (step 1004).

  Next, processing in which the monitoring center 1 distributes observation messages, alarm messages, and notification messages to the maintenance staff terminal 3 will be described with reference to FIGS. 11 and 12.

  This process is the most characteristic process in the first embodiment, and is executed by the information distribution program 28.

  FIG. 11 is a process flowchart of the information distribution program 28.

  As shown in FIG. 11, the information distribution program 28 first acquires the attribute information of all maintenance personnel terminals 3 from the spatial information management DB 21 and expands the distribution condition table 120 shown in FIG. 12 on the memory (step 1101). .

  Here, the distribution condition table 120 will be described.

  As a premise, the monitoring field of the maintenance support system according to the first embodiment is divided into a plurality of areas, and maintenance personnel (maintenance personnel terminal 3) to be in charge are determined in advance for each area. That is, for each maintenance staff terminal 3, an ID, a telephone number, and a responsible area are registered in advance in the spatial information management DB 21 as attribute information. Further, the attribute information includes a distribution method and a distribution information type described below.

  Therefore, the distribution condition table 120 developed on the memory by the information distribution program 28 includes a maintenance staff terminal ID 121, a telephone number 122, a charge area 123, a distribution method 124, and a distribution information type 125, as shown in FIG.

  As will be described later, the distribution condition table 120 is also read and written from the terminal message reception program 29, and the setting contents of the assigned area 123, distribution method 124, and distribution information type 125 are changed in response to a request from the maintenance staff terminal 3. Is done.

In the distribution condition table 120 shown in FIG. 12, information to be distributed to the maintenance staff terminal 3 is set in the distribution method 124. In the first embodiment, specifically,
(1) Distribute information generated in the assigned area (2) Distribute information generated in the current area (3) Distribute information generated in the specified area (4) Pre-designated from the current position of the maintenance staff terminal 3 It is assumed that one of four types of distribution of information generated within a predetermined distance (for example, 1 km) is set.

In addition, in the distribution information type 125, the type of information to be distributed to the maintenance staff terminal 3 is set. In the first embodiment, specifically,
(1) All types of information (2) Alarm information and notification information (3) One of three types of status information, alarm information, and notification information shall be set.

  Returning to FIG. 11, the information distribution program 28 loads the distribution condition table 120 on the memory, and then captures any message by inter-process communication (step 1102).

  Then, the information distribution program 28 obtains the occurrence area of information notified by the message from the position information 72 set in the fetched message (step 1103), and obtains the obtained information occurrence area from the spatial information management DB 21. The maintenance engineer terminal 3 that is traveling is searched (step 1104). The current position of each maintenance staff terminal 3 is registered in the spatial information management DB 21 and the registration method will be described later.

  Subsequently, the information distribution program 28 searches the maintenance staff terminal 3 that matches the distribution conditions with reference to the information generation area, the maintenance staff terminal 3 that is circulating in the information generation area, and the distribution condition table 120 (step 1105). .

  As a result of the search, if there is no maintenance staff terminal 3 serving as a delivery destination (step 1106), the process returns to step 1102, and if there is a maintenance staff terminal 3 serving as a delivery destination (step 1106), a communication with the maintenance staff terminal 3 is performed. A line connection is made (step 1107), and the message type is checked from the information type 74 set in the fetched message (step 1108).

  If the message type is an observation message (step 1108), the information distribution program 28 transmits an observation message (step 1109) and disconnects the line (step 1112).

  If it is either an alarm message or a notification message (step 1108), the information distribution program 28 is further registered in association with the occurrence area of the information notified by the message from the spatial information management DB 21. The area related information is searched (step 1110). The spatial information management DB 21 stores, for each area, past observation information, past alarm information, past report information, past work report information, and the like associated with each other as area-related information. In one embodiment, if any of the alarm message and the notification message is used, there is a high possibility that an emergency operation is performed by the maintenance staff. Also trying to deliver.

  Therefore, the information distribution program 28 sets the searched area related information in the data 75 of the message to be distributed and transmits it (step 1111), and disconnects the line (step 1112). The area related information may be transmitted as a separate message together with the message to be distributed.

  After message distribution to all maintenance personnel terminals 3 matching the distribution conditions is completed (step 1113), the information distribution program 28 returns to step 1102 and waits for message reception by inter-process communication.

  Here, a specific example of message distribution will be described.

  It is assumed that four maintenance personnel terminals 3 with maintenance personnel terminal IDs = 1, 2, 3, and 4 exist in A district, B district, C district, and D district, respectively, and the contents of distribution condition table 120 are shown in FIG. A specific example will be described.

  For example, when the monitoring center 1 acquires status information from the A district, the maintenance personnel terminal ID in which the responsible area 123 is “A district”, the distribution method 124 is “responsible area”, and the distribution information type 125 is “all types”. = 1 maintenance personnel terminal 3 and maintenance method terminal 3 with distribution method 124 “area A area designation” and distribution information type 125 “status information, alarm information, report information” For each, status information is distributed.

  Further, for example, when the monitoring center 1 acquires alarm information from the B district, the maintenance staff who is currently in the B district, the delivery method 124 is “present location”, and the delivery information type 125 is “alarm information, report information”. Alarm information (and area-related information in the B district) is distributed to the maintenance staff terminal 3 with terminal ID = 2.

  Also, for example, when the monitoring center 1 acquires status information from the D district, if the current position of the maintenance staff terminal 3 with the maintenance staff terminal ID = 4 is within 1 km from the information acquisition position, the distribution information type Since 125 is “all types”, the status information is distributed to the maintenance staff terminal 3 having the maintenance staff terminal ID = 4.

  Thus, the four maintenance personnel terminals 3 with maintenance personnel terminal IDs = 1, 2, 3 and 4 each include information on the area in charge, the district in the current area, the district in the designated area, and the district within the designated distance. Is delivered.

  Next, when the monitoring center 1 receives the position information transmission processing from the maintenance staff terminal 3, the work report information transmission processing from the maintenance staff terminal 3, the information distribution condition registration processing from the maintenance staff terminal 3, and so on. Will be described with reference to FIGS. 13 to 15.

  In the maintenance staff terminal 3, the transmission process of the location information is performed by the GPS location report program 42 that is activated periodically.

  FIG. 13 is a process flowchart of the GPS position report program 42.

  As shown in FIG. 13, the GPS location report program 42 first detects the current location by the GPS device 3a (step 1301), and creates a terminal location information message in which the detected location information is set (step 1302). Then, a line connection is established with the monitoring center 1 (step 1303), a terminal location information message is transmitted (step 1304), and the line is disconnected (step 1305).

  In the maintenance staff terminal 3, work report information transmission processing and information distribution condition registration processing are performed by the business support program 47.

  FIG. 14 is a process flowchart of the business support program 47.

  As shown in FIG. 14, the business support program 47 first checks the business content (step 1401). If it is a work report creation, it accepts input of work report data according to the operation of the maintenance staff (step 1402). ), Accepting input of image data of the work place (step 1403). Then, a work report message is created in which the input work report data and video data are set as work report information (step 1404).

  Further, if the business content is distribution condition registration, the business support program 47 accepts input of the registered content of the area in charge, the distribution method, and the distribution information type according to the operation of the maintenance staff (step 1405), and the input registration A delivery condition registration message with the contents set is created (step 1406).

  After creating the message, the business support program 47 establishes a line connection with the monitoring center 1 (step 1407), transmits the created message (step 1408), and disconnects the line (step 1409).

  The terminal location information message, work report message, and delivery condition registration message transmitted from the maintenance staff terminal 3 are processed by the terminal message reception program 29 in the monitoring center 1.

  FIG. 15 is a process flowchart of the terminal message reception program 29.

  As shown in FIG. 15, the terminal message reception program 29 is in a line connection waiting state from the maintenance staff terminal 3 (step 1501), and when connected and receives a message (step 1502), it is set in the received message. The stored information is stored in the spatial information management DB 21 (step 1503). That is, if the received message is a work report message, it is newly registered in the spatial information management DB 21, and if it is a terminal location information message and a distribution information registration message, the registered contents are updated.

  At this time, the terminal message reception program 29 checks the message type of the received message (step 1504). If it is a terminal position information message, the terminal position information message is further transmitted to the center screen display program 23 by inter-process communication. Is transmitted (step 1505), and if it is a distribution condition registration message, the distribution condition table 120 developed in the memory is further updated (step 1506).

  Thereafter, the terminal message reception program 29 disconnects the line with the maintenance staff terminal 3 (step 1507), returns to step 1501, and again enters a line connection waiting state.

  Through these processes, the monitoring center 1 can periodically grasp the current position of each maintenance staff terminal 3 and accumulate work report information created by the maintenance staff. Further, the distribution condition table 120 can be updated in response to a request from the maintenance staff.

  Next, screen display in the monitoring center 1 will be described.

  The screen display at the monitoring center 1 is performed by the center screen display program 23.

  FIG. 16 is a processing flowchart of the center screen display program 23.

  As shown in FIG. 16, the center screen display program 23 first displays a map and distribution facilities on the screen based on the map information and distribution facility information stored in advance in the space information management DB 21 (step 1601). Above, the symbol of the monitoring station 2 and the symbol of the maintenance staff terminal 3 are displayed in a mapping manner (steps 1602 to 1603). The screen displayed so far is the initial screen.

  After the initial screen is displayed, the center screen display program 23 enters an event waiting state (step 1604), receives a message by inter-process communication (step 1605), and if the received message is a terminal location information message (step 1606). ), The position of the symbol of the corresponding maintenance staff terminal 3 is changed based on the maintenance staff terminal ID and location information set in the terminal location information message (step 1607). If the received message is an observation message (step 1606), the center screen display program 23 displays the observation information set in the observation message on the screen (step 1609), and either the alarm message or the notification message is displayed. If so (step 1606), the alarm information or report information set in the message is displayed on the screen (step 1608).

  FIG. 17 shows a screen display example at the monitoring center 1.

  In FIG. 17, 171 is a monitoring field status window, 172 is an observation window, and 173 is an alarm / report window.

  Therefore, the center screen display program 23 sets the monitoring field status window 171 to the initial screen status in steps 1601 to 1603, and changes the position of the corresponding symbol in the monitoring field status window 171 in step 1607.

  In step 1609, the center screen display program 23 displays the monitoring station ID, position information, time information, and information type set in the observation message in the observation window 172, and the information type is a status value. If present, the status value is also displayed.

  In step 1608, the center screen display program 23 displays the position information, time information, and alarm / report information set in the alarm message or report message in the alarm / report window 173, and further displays the position information. The area including the position indicated by is also displayed.

  On the other hand, the center screen display program 23 waits for an event, and when an operation (selection operation of the symbol of the monitoring station 2) is performed from the commander on the monitoring field status window 171 (step 1604), the selected monitoring is performed. Information relating to the station 2 is extracted from the spatial information management DB 21 and displayed on the screen (step 1610). Further, when an operation from the commander (message selection operation) to the observation window 172 or an operation from the commander (message selection operation) to the alarm / report window 173 is performed while waiting for an event (step 1604). ), The detailed information of the selected message is extracted from the spatial information management DB 21 and displayed on the screen (step 1610).

  As a result, the commander can intuitively understand the location and state of the information stored in the spatial information management DB 21 and can view the collected information with a simple operation.

  Finally, screen display on the maintenance staff terminal 3 will be described.

  The screen display on the maintenance staff terminal 3 is performed by the terminal screen display program 44.

  An example of a screen display on the maintenance staff terminal 3 is shown in FIG.

  Since the navigation function 43 is added to the terminal screen display program 44, the maintenance staff terminal 3 has map information in a predetermined range centered on the current position of the maintenance staff terminal 3, as shown in FIG. The distribution facility information and the symbol of the monitoring station 2 are displayed. That is, the maintenance staff terminal 3 is different from the screen display in the monitoring center 1 in that the display range is limited and the symbols of the other maintenance staff terminals 3 are not displayed. Is similar to the screen display in the monitoring center 1.

  Here, the contents displayed in the observation window and the alarm / report window are information set in the message distributed from the monitoring center 1, and the message distributed from the monitoring center 1 in the maintenance staff terminal 3 is: It is processed by the spatial information receiving program 46. Therefore, prior to the description of the terminal screen display program 44, the spatial information reception program 46 will be described.

  FIG. 18 is a process flowchart of the spatial information receiving program 46.

  As shown in FIG. 18, the spatial information receiving program 46 is in a line connection waiting state from the monitoring center 1 (step 1801), and when it is connected to the line and receives a message (step 1802), The set information is stored in the spatial information management DB 45 (step 1803). Then, the received message is transmitted to the terminal screen display program 44 by inter-process communication (step 1804), and then the line is disconnected (step 1805).

  As shown in FIG. 19, the terminal screen display program 44 first displays a map and distribution facilities on the screen based on the map information and distribution facility information stored in advance in the spatial information management DB 45 (step 1901). Above, the symbol of the monitoring station 2 is mapped and displayed (step 1902). The screen displayed so far is the initial screen. However, as shown in FIG. 20, the map displayed on the screen in step 1901 is a limited range map centered on the current position of the maintenance staff terminal 3, and the distribution facility and the symbol of the monitoring station 2 Only those that exist within the map area are displayed.

  After the initial screen is displayed, the terminal screen display program 44 enters an event waiting state (step 1903). When a message is received by inter-process communication (step 1904), if the received message is an observation message (step 1905), The observation information set in the observation message is displayed in the observation window (step 1906), and if it is either an alarm message or a notification message (step 1905), the alarm information or notification information set in the message Is displayed in the alarm / report window (step 1907).

  In step 1907, the terminal screen display program 44 displays the area-related information added to the alarm message or report message in the alarm / report window so that the relation can be understood.

  On the other hand, the terminal screen display program 44 waits for an event, and when an operation (selection operation of the symbol of the monitoring station 2) is performed from the commander to the monitoring field status window (step 1903), the selected monitoring station 2 is extracted from the spatial information management DB 45 and displayed on the screen (step 1908). Also, when an operation from the commander for the observation window (message selection operation) or an operation from the commander for the alarm / report window (message selection operation) is performed while waiting for an event (step 1903), The detailed information of the selected message is extracted from the spatial information management DB 45 and displayed on the screen (step 1908).

  Further, when the current position of the maintenance staff terminal 3 is changed while waiting for an event (step 1903), the terminal screen display program 44 retrieves necessary data from the spatial information management DB 45 again and displays the field status window. Reconstruction is performed (step 1909).

  According to the first embodiment, by the processing of the monitoring center 1, the monitoring station 2, and the maintenance staff terminal 3 described above, the maintenance staff can perform the distribution conditions registered in advance and the self without performing troublesome inquiry work. Depending on the current position, necessary information of information generated in the monitoring field can be received in real time. The transmission at the time of information distribution is from the monitoring center 1 side, and is real push type information distribution.

In particular, when an alarm / report occurs, there is a high possibility that an emergency operation will be performed by maintenance personnel. At this time, the maintenance personnel can also receive area-related information together, so that the maintenance center 1 is independent. Emergency operations.
(Second Embodiment)
Next, a second embodiment will be described.

The type of information (for example, observation information, alarm information, report information, work report information, etc.) is set.

  Then, the request program establishes a line connection with the monitoring center 1 (step 2102) and transmits a request message (step 2103).

  Since the response message is transmitted from the monitoring center 1 that has received the request message by the processing of the request reception program described later, the request message is set in the received response message when the response message is received (step 2104). The stored information is stored in the spatial information management DB 45 (step 2105). The received response message is transmitted to the terminal screen display program 44 by inter-process communication (step 2106), and the line is disconnected (step 2107).

  On the other hand, in the monitoring center 1, the request message transmitted from the maintenance staff terminal 3 is processed by the request reception program.

  FIG. 23 is a process flowchart of the request reception program.

  As shown in FIG. 23, the request reception program is in a state of waiting for a selection connection from the maintenance staff terminal 3 (step 2301). When the request reception program is connected and receives a request message (step 2302), it is requested by the received request message. The acquired information is acquired from the spatial information management DB 21 (step 2303), a response message in which the acquired information is set is created and transmitted (step 2304), and the line is disconnected (step 2305).

  The format of the response message is the same as the format shown in FIG.

According to the second embodiment, by the processing of the maintenance staff terminal 3 and the monitoring center 1 described above, especially when an alarm / report occurs, the maintenance staff receives the area-related information list together, and the necessary information is included. Only information can be obtained from the monitoring center 1. Thus, by listing the area related information, the amount of data transmitted to the maintenance staff terminal 3 can be reduced.
