  However, the wide area disaster support system as described above provides each worker with the shortest route for the next restoration target elevator from the current work position, and informs the situation of the disaster over a wide area. Not.

  Therefore, conventional general disaster communication uses a method in which a disaster maintenance service center or service base notifies the status of a disaster to a mobile terminal possessed by each worker by telephone or e-mail. Therefore, each worker creates a list of elevators to be restored in places to be visited on the day based on the disaster situation provided from the disaster maintenance service center or service base. Then, the vehicle travels according to the created list of restoration target elevators and carries out restoration work.

  However, it is difficult to properly communicate the disaster status of each recovery target elevator from the disaster maintenance service center or service base to each worker, and a list of recovery target elevators is created for each worker, The disaster situation is written in. For this reason, there is a problem that a lot of time is spent on creating a list of restoration target elevators and writing the disaster situation, and the subjective judgment of each worker is easy to enter.

  Furthermore, in the event of a wide-area disaster, there may be cases where each worker makes inquiries by telephone or e-mail regarding the disaster situation. However, the disaster maintenance service center or service base cannot respond individually, or the communication path may be due to congestion of the line. Since it is not established, a communication impossible state occurs. This has the problem that disaster information of the restoration target elevator cannot be quickly communicated to many workers.

  The present invention has been made in view of the above circumstances.

  The elevator control panel 2 is connected to a storage device 21 for storing operation status data in addition to a normal operation control program and various control operation control programs including earthquakes. A report determination unit 23 and a transmission / reception unit 24 are provided.

  When the operation control unit 22 receives a hall call or a car call, the operation control unit 22 registers the call according to the normal operation control program, and then sends a rotational drive command to the hoisting machine 12 so that the car 14 is directed to the destination floor. Execute normal operation control. When a seismic detection signal of a predetermined seismic intensity level (P wave or extra low gal) is received from the seismic detector 16, the seismic control operation control is performed according to the seismic control operation control program, and a monitoring device such as a monitoring room is provided. When a fire occurrence signal is received from 3, fire control operation control is carried out according to the fire control operation control program, operation status data as a result of operation control from each required location, earthquake detection signal, load under the car frame A car load signal or the like for confirming the presence or absence of a person in the car is taken from a detector (not shown), stored in the storage device 21, and sent to the monitoring device 3 as necessary.

  The abnormality report determination unit 23 determines whether the user is trapped from the car load signal or the emergency report signal generated by operating the emergency call button 14a after stopping the car to a predetermined floor by various control operations, or the operation control unit 22. In spite of having performed predetermined operation control from, when an abnormality is received from the operation status data, an abnormality report including abnormality content is transmitted to the transmission / reception unit 24.

  The transmission / reception unit 24 sends the operation status data to the monitoring device 3 every predetermined cycle, and immediately sends the abnormality report from the abnormality notification determination unit 23 to the monitoring device 3.

  The monitoring device 3 corresponds to a remote monitoring device connected via a communication network such as a management room of a building where an elevator is installed or a telephone communication line, LAN, WAN, etc., and constantly monitors the operation state of the elevator, Based on the monitoring results, an optimal operation control command is sent to the elevator control panel 2 side, and an abnormality report transmitted from the elevator control panel 2 together with the property identification data (elevator identification data) is transmitted via telephone communication line, LAN, WAN, etc. To the maintenance service management center 4 via the network 6. In addition, the manager or the supervisor of the monitoring device 3 installed in the management room recognizes the abnormality directly and maintains the disaster status data including the property identification data without receiving an abnormality report from the elevator control panel 2. It may be transmitted to the service management center 4.

  As shown in FIG. 2, the maintenance service management center 4 inputs information for creating various tables, an input unit 41 such as a keyboard and a mouse for inputting necessary setting data, and a maintenance management composed of a CPU. A processing unit 42, a display unit 43, and a maintenance management database 44 are provided, and a disaster situation providing server 45 is connected via an internal network such as a LAN.

  The maintenance management database 44 stores a disaster situation with property identification data in the order of abnormality notification when receiving an abnormality report including a disaster situation (disaster content) with property identification data from a plurality of monitoring devices 3,. Maintenance that registers a status storage unit 44a, a maintenance target property table 44b (see FIG. 3) that stores data for specifying a maintenance target property, and a maintenance staff dispatched to the maintenance target property (to become a disaster recovery worker in the event of a disaster) Service area map information storage unit for storing map information of at least the maintenance service management area, in addition to a worker registration table 44c (see FIG. 4) and a disaster situation mark table 44d (see FIG. 5) for registering symbol marks according to the disaster situation 44e is provided.

  The maintenance management processing unit 42 is a disaster target property, worker (maintenance worker), property registered in each of the tables 44b to 44d based on the disaster status with the property identification data stored in the disaster status storage unit 44a when a wide-area disaster occurs. A disaster dispatch table (refer to FIG. 6) composed of symbol marks representing the abnormality content is created and stored in the maintenance management database 44.

  The disaster situation providing server 45 reads the map information of the maintenance service area from the service area map information storage unit 44e of the maintenance management database 44, and uses the map information of the service area, for example, using HTML (markup) language. A disaster recovery map describing the disaster situation including the contents of the disaster dispatch table (see FIG. 6), for example, disaster recovery target property, dispatch worker, symbol mark, etc. is created and stored in the disaster situation information storage unit 46.

  Accordingly, the maintenance personnel 7a, 7b,... Scattered in each service area access the disaster situation providing server 45 via the portable terminal (for example, a mobile phone) 8 and browse the disaster recovery map describing the disaster situation. can do. Reference numeral 9 denotes a base station connected to the network 6. That is, the portable terminal 8 possessed by the maintenance personnel 7a, 7b,... Can exchange the disaster recovery map described in the language of HTML with the disaster situation providing server 45 using the Hyper Text Transfer Protocol (HTTP). To.

The disaster situation providing server 45 may store map information of all maintenance service areas in advance. Next, the operation of the wide area disaster communication system as described above and the wide area disaster communication method according to the present invention will be described with reference to FIG. Will be described with reference to FIG.

  The elevator control panel 2 of each elevator shifts to seismic control operation control when a wide-area disaster such as an earthquake occurs and receives an earthquake detection signal of a predetermined seismic intensity level (P wave or extra low gal) from the earthquake detector 16. However, depending on the magnitude of the earthquake, building fires, power outages, elevator equipment breaks, water leakage into the pits, and passenger car confinement, etc.

  At this time, the abnormality report determination unit 23 of the elevator control panel 2 determines the car confinement state of the user from the car load signal or the emergency report signal generated by the operation of the emergency call button 14a after the control operation and during the control operation. When other abnormality is determined from the situation data, an abnormality report including the disaster situation is sent to the monitoring device 3 through the transmission / reception unit 24.

  Here, when the monitoring device 3 receives an abnormality report including a disaster situation, and when necessary, a monitoring person of the monitoring device 3 determines various disaster situations of the elevator car lifting equipment system 1 and obtains the property identification data. An abnormality report including the accompanying disaster situation (disaster content) is transmitted to the maintenance service management center 4 through the network 6.

  When a wide-area disaster occurs, the maintenance service management center 4 receives an abnormality report from a large number of monitoring devices 3,... Scattered in the maintenance service management area. The data is sequentially stored in the disaster situation storage unit 44a of the maintenance management database 44.

  When the maintenance service management center 4 receives a disaster dispatch table creation instruction from the input unit 41 by an operator, the maintenance service management center 4 executes a disaster dispatch table creation process shown in FIG.

  That is, the maintenance service management center 4 refers to the disaster situation storage unit 44a of the maintenance management database 44 and determines whether there is an abnormality report (S1). When it is determined that there is an abnormality report, based on the property identification data included in the abnormality report transmitted from the monitoring device 3, the property location data corresponding to the same property identification data is referred to the maintenance target property table 44b shown in FIG. (Latitude / longitude data), building name, and maintenance area name are read out, sequentially registered in a predetermined area of the disaster dispatch table shown in FIG. 6, and displayed on the display unit 43 (S2).

  Note that the maintenance service management center 4 receives the disaster dispatch table creation instruction or after the disaster dispatch table is displayed in step S2, the maintenance staff registration table 44c shown in FIG. Is displayed in a window. Whether the operator has been dispatched near the restoration target elevator that has already issued an error report from the maintenance staff registration table 44c or the maintenance staff dispatch schedule table, or whether the operator has not been dispatched yet and is waiting The dispatch worker name is input from the input unit 41 and written in the corresponding area of the disaster dispatch table (S3).

  Further, the maintenance service management center 4 writes the dispatched maintenance staff name in the disaster dispatch table, and then, based on the disaster situation sent together with the abnormality report, the symbol corresponding to the disaster situation from the disaster situation mark table 44d shown in FIG. Marks (graphics, etc.) or character data (eg, kana characters, etc.) are read out, registered in the disaster dispatch table as shown in FIG. 6, and stored in the maintenance management database 44 (S4, S5).

  Then, it is determined whether or not the processing of all the properties that received the abnormality report has been completed (S6), and if there are still properties of the abnormality notification in the disaster status storage unit 44a, the process returns to step S2 and the same processing is performed. Repeatedly.

  In step S6, when the registration process for all abnormality report properties is completed, the process proceeds to the next step S7, where it is determined whether or not to continue the process from a preset flag (S7). After the elapse (S8), the process proceeds to step S1 again, and the same process is repeatedly executed.

  As a result, a new property to be restored that is generated during a predetermined time is registered, or a disaster dispatch is always automatically performed by receiving the notification of the restoration completed property and deleting the contents of the disaster status storage unit 44a. The table can be updated.

  On the other hand, the disaster situation providing server 45 reads the map information from the service area map information storage unit 44e of the maintenance management database 44 and replaces it with the map information of the maintenance service management area described in the language of HTML. Read the contents of the disaster dispatch table shown in Fig. 6, and based on the property location data that is the source of the abnormality report, the name of the building and the dispatch worker who will be the target for disaster recovery at the corresponding property location on the map information in the maintenance service management area , The disaster recovery management map data in which the symbol mark or character data representing the disaster situation is written is created and stored in the disaster situation information storage unit 46 so as to be viewable.

  Therefore, each disaster recovery worker (maintenance worker) 7a, 7b,... Selects the wide area disaster menu from the menus displayed on the portable terminal 8 possessed by himself / herself when a wide area disaster occurs, and the disaster situation providing server 45 Is accessed, a disaster recovery management map is provided from the disaster situation providing server 45 and can be displayed on the display unit of the portable terminal 8.

  The displayed disaster recovery management map is a regional map that includes disaster names based on the names of disaster-causing buildings, dispatched workers, and symbol marks. Information, property stoppage abnormalities, pit leakage, fire damage, etc.), and without creating a list of properties to be restored (recovery elevators) You can easily find the property to be restored.

  The mobile terminal 8 can also exchange information shown in FIG. 8 with the disaster situation providing server 45. When the dispatch worker selects the wide area disaster menu from the menu displayed on the display unit of the portable terminal 8 (S11), the disaster recovery management map is taken in from the disaster situation providing server 45 under the access by the URL, A disaster recovery management map describing the disaster recovery target property is displayed on the display unit (S12).

  Here, when the dispatch worker selects a disaster recovery target property on the map that he or she is in charge of (S13), the disaster situation providing server 45 determines that there is a dispatch (dispatch check), and the disaster dispatch shown in FIG. For example, a circle mark is added to the dispatch area of the disaster recovery target property on the table to notify that the property is moving or heading for the recovery target property. When the disaster recovery target property on the map in charge is not yet selected, the process returns to step S12 to repeat whether or not the disaster recovery target property is selected.

  When the mobile terminal 8 selects the disaster recovery target property, the mobile terminal 8 stores the selected property name, so it continues to determine whether or not the disaster recovery target property has arrived (S14). If the property has not yet arrived at the disaster recovery target property, the process returns to step S12 to repeat the same processing.

  When the dispatch worker arrives at the recovery target property and inputs an arrival instruction, the mobile terminal 8 stores the arrival at the disaster recovery target property and transmits the arrival instruction data with the target property to the disaster situation providing server 45. .

  Here, the disaster situation providing server 45 determines that it has arrived at the corresponding recovery target property (arrival check), and adds, for example, a check mark to the arrival area of the target recovery target property on the disaster dispatch table. Inform.

  Furthermore, the portable terminal 8 determines whether or not an instruction to complete the restoration work for the disaster restoration target property has been input (S15). When there is no instruction for completion of the recovery work, the process returns to step S12 and the same process is repeatedly executed.

  Here, when the portable terminal 8 receives the restoration work completion instruction, the portable terminal 8 transmits the restoration work completion instruction data with the target property to the disaster situation providing server 45. The disaster situation providing server 45 determines that the recovery work for the corresponding recovery target property has been completed, and marks the recovery area of the target recovery target property on the disaster dispatch table with, for example, a circle to notify the recovery.

  Thereafter, after completion of the recovery work for the disaster recovery target property, it is determined whether or not to continue the process based on a preset flag (S16). If the process is continued, the process returns to step S12 to carry the mobile phone. A disaster recovery management map is displayed on the display unit of the terminal 8. If the process is not continued, the process ends.

  In addition, as a result of investigating the property to be recovered by the worker, if it is determined that recovery is difficult at present, a call is made from the mobile terminal 8 to the maintenance service management center 4 to notify the reason for recovery and the next disaster Select the property to be restored.

  Therefore, according to the above embodiment, when a wide-area disaster occurs, the disaster situation providing server 45 of the maintenance service management center 4 is accessed through the portable terminal 8 possessed by each restoration worker 7a, 7b,. Since the disaster recovery management map with the disaster situation is provided, the maintenance service management center 4 individually contacts each recovery worker, or the maintenance service management center 4 performs maintenance management from the mobile terminal 8 side of each recovery worker. Without asking the status of the property, it is possible to quickly grasp the property to be restored by itself and the disaster status of the property.

  In addition, after each recovery worker 7a, 7b,... Displays the disaster recovery management map with the disaster situation provided from the disaster situation provision server 45 by selecting the wide area disaster menu from the portable terminal 8, he / she is in charge. By selecting the property to be restored, it is possible to notify the maintenance service management center 4 of the state in which the restoration is impossible, in addition to the dispatch, arrival of the property, completion of the restoration work.

  Furthermore, since the service base 5 is linked to the maintenance service management center 4, by reading and displaying the disaster dispatch table in the maintenance management database 44, it is possible to check the progress of recovery for a wide-area disaster, A support system can be quickly established.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

(1) In the above embodiment, it is possible to provide a disaster recovery management map with a disaster situation describing the name of a disaster recovery target property, a recovery worker, and the disaster situation from the disaster situation providing server 45 of the maintenance service management center 4. However, based on the contents of the disaster dispatch table shown in FIG. 6, for example, a sort processing function is used to create a disaster dispatch table corresponding to FIG. You may make it possible to provide a disaster recovery management map with a situation.

  With such a configuration, each of the recovery workers 7a and 7b accesses the disaster situation providing server 45 from the portable terminal 8, and if the recovery worker is input and transferred, the corresponding restoration work is performed from the disaster situation providing server 45. It is possible to receive a disaster dispatch table or a disaster recovery management map with a disaster situation that the employee is in charge of and display on the display unit of the mobile terminal 8.

(2) In general, the display area of the portable terminal 8 is small, but by adding a scroll function, if the disaster recovery management map is scrolled, each recovery worker can be sure over a wide range of maintenance service areas. It is possible to grasp the disaster situation.
