Embodiment 1 FIG.
1 is a block diagram showing an elevator control system according to Embodiment 1 of the present invention. In the figure, the elevator control device 1 controls the operation of the elevator. An earthquake detection signal from the earthquake detector 2 is input to the elevator control device 1. The earthquake detector 2 is installed in a building where an elevator is installed.

  The elevator control device 1 can also receive an earthquake detection signal (real-time earthquake information) from the earthquake information transmission device 3 installed in the Japan Meteorological Agency. The earthquake detection signal from the earthquake information transmitting device 3 is input to the elevator control device 1 via the server 4, the receiver 5 and the interface 6, or via the server 7, the router 8 and the interface 6.

  When an earthquake of a predetermined level or higher is detected, the elevator control device 1 performs an earthquake control operation. In the control operation during an earthquake, the elevator is stopped after the car is moved to the nearest floor.

  In addition, the elevator control device 1 performs an automatic diagnosis operation (automatic recovery operation) for checking whether there is an abnormality in the elevator equipment after a predetermined time from the end of the earthquake control operation. In the automatic diagnosis operation, the car 4 is driven at an extremely low speed (for example, 4 m / min or less) sufficiently lower than the rated speed, and it is automatically checked whether or not the elevator can be operated normally.

  As an item to be inspected, for example, the presence or absence of catching of a cord-like body such as a main rope, a governor rope, and a control cable can be mentioned. The hook of the cord-like body is detected based on, for example, the traveling direction of the car, the torque signal of the hoisting machine, and the scale signal from the scale device. Further, in the automatic diagnosis operation, for example, the abnormality of the elevator device can be detected from the frequency and level of noise generated in the hoistway.

  After the occurrence of the earthquake, the elevator control device 1 causes automatic notification related information, which is information related to automatic diagnosis operation, to be notified by a notification device 9 provided in at least one of the hall and the car. As the notification device 9, for example, a display device provided in the hall and the car, a floor indicator provided in the hall and the car, an announcement device provided in the hall and the car, a dedicated display device, and the like can be used. .

Moreover, the elevator control apparatus 1 records automatic diagnosis history information in which automatic diagnosis related information is associated with time information. The elevator control device 1 is provided with a timepiece for obtaining time information.

  An elevator monitoring device 10 that monitors all elevator control devices in the building is connected to the elevator control device 1. The elevator monitoring apparatus 10 is installed in a management center in a building, for example. The elevator control device 1 transmits automatic diagnosis history information to the elevator monitoring device 10. The elevator monitoring apparatus 10 can display the contents of automatic diagnosis history information as necessary.

  The diagnostic operation control unit 11 includes an elevator control device 1 and an elevator monitoring device 10. Each of the elevator control device 1 and the elevator monitoring device 10 includes a computer having an arithmetic processing unit (CPU), a storage unit (ROM, RAM, hard disk, etc.), and a signal input / output unit.

  The elevator monitoring device 10 is connected to a remote monitoring device 12 as a remote monitoring unit via a communication line (telephone line, private IP line, Internet line, etc.). The remote monitoring device 12 is installed, for example, in a maintenance company monitoring center remote from the building where the diagnostic operation control unit 11 is installed. The elevator monitoring device 10 transmits automatic diagnosis history information to the remote monitoring device 12. The remote monitoring device 12 can display the contents of automatic diagnosis history information as necessary.

  The remote monitoring device 12 can transmit at least a part of the automatic diagnosis history information to the communication terminal 13 in response to a request from the communication terminal 13 connected via the communication network. Examples of the communication terminal 13 include a personal computer and a mobile phone. Further, the remote monitoring device 12 determines whether or not automatic diagnosis history information can be transmitted to the communication terminal 13 based on the identification information (ID, password, etc.) received from the communication terminal 13.

  Specifically, the remote monitoring device 12 posts at least a part of the automatic diagnosis history information on the website. The information posted on the Web site can be confirmed after authentication by an authentication means issued by a maintenance company to a maintenance contract customer (owner, management company, etc.). Thereby, the maintenance contract customer can confirm the state of the target elevator without calling the maintenance company even when the telephone line of the maintenance company is congested.

  The remote monitoring device 12 can input maintenance staff information, which is information related to the service status of the elevator by the maintenance staff. The maintenance staff information includes, for example, maintenance staff arrangement status information (arranged / not arranged), maintenance staff arrival scheduled time information, maintenance staff arrival time information, information indicating a time when the elevator is restored by the maintenance staff, and the like. be able to. In addition, when it is difficult for a maintenance person to recover, it is possible to input recovery difficulty information such as information on a damaged portion, parts arrangement information, and expected recovery time information to the remote monitoring device 12.

  The maintenance staff information and the recovery difficulty information input to the remote monitoring device 12 are transmitted to the elevator monitoring device 10. When the elevator monitoring device 10 receives the maintenance staff information and the recovery difficulty information, the elevator monitoring device 10 transmits at least a part of the information to the elevator control device 1 as necessary and causes the notification device 9 to notify it.

  Further, when the elevator monitoring device 10 reports the diagnosis history information to the remote monitoring device 12, the elevator monitoring device 10 creates report status information (notifying, reporting retry, reporting completed, etc.), and the information is sent to the elevator control device as necessary. 1 and is notified by the notification device 9.

  A maintenance tool 14 can be connected to the elevator monitoring device 10. The notification contents and notification availability in the notification device 9 for each elevator state can be arbitrarily set from the maintenance tool 14 or the remote monitoring device 12. For example, when the elevator recovers normally, it is possible to set so that automatic diagnosis related information is not notified.

  Here, when the notification device 9 is a display device, a message corresponding to the automatic diagnosis related information can be displayed on the display device. At this time, an appropriate fixed phrase is selected from a plurality of fixed phrases registered in advance according to the automatic diagnosis related information, and a part of the selected fixed sentence is partially replaced according to the automatic diagnosis related information. If a message is created by the above, the amount of memory used for message display can be reduced. For example, in the following display examples (1) to (3), the portion indicated by “◯” is a portion to be replaced according to the automatic diagnosis related information.

Display example (1)
“A shake equivalent to seismic intensity ○ was detected at ○ year ○ month ○ day, ○ hour ○ minute ○ second, and stopped.
Reactivation was performed because the detected shaking was slight.
Since each device is operating normally, please use it with confidence.
As a precaution, we asked a maintenance company to check. "

Display example (2)
“A shake equivalent to seismic intensity ○ was detected at ○ year ○ month ○ day, ○ hour ○ minute ○ second, and stopped.
On behalf of a professional engineer, we performed automatic diagnostic operation of equipment.
Since each device is operating normally, we provide normal service.
As a precaution, we asked a maintenance company to check. "

Display example (3)
“A shake equivalent to seismic intensity ○ was detected at ○ year ○ month ○ day, ○ hour ○ minute ○ second, and stopped.
When an automatic diagnosis operation is performed, the service is stopped because an error is detected at XX.
The maintenance company has been contacted. Please wait a while. "

  In addition, when a display device with a small content that can be displayed at a time, such as a floor indicator, is used as the notification device 9, characters such as kanji, hiragana, katakana, and alphabet are sequentially switched one by one in accordance with the capability of the display device. Show it. By repeating such display for a predetermined time, it is possible to convey automatic diagnosis related information to the user, owner, maintenance staff, and the like.

  FIG. 2 is a front view showing a floor indicator which is an example of the notification device 9 of FIG. In this example, the floor number (“5” in the figure) is displayed by blinking the light emitters 9a arranged at 5 × 7. As a method of displaying automatic diagnosis related information using such a floor indicator, for example, a combination with reverse display as shown in FIG. 3 can be used.

  For example, when the service is stopped on the fifth floor and the service is disabled, the display in FIG. 2 and the display in FIG. 3 are alternately repeated. In addition to this, the time of reverse display can be made to correspond to the state of the elevator. For example, if the reverse display time is preset to 1 second in state A, 2 seconds in state B, 4 seconds in state C, etc., the state of the elevator related to automatic diagnosis operation is maintained. Easy to understand.

  It is also possible to increase the information to be displayed by performing reverse display at different times across the normal floor display. For example, when the service is not available on the 5th floor, and the report to the maintenance company is completed, the maintenance can be performed by switching the display in the order of normal display, 2 second reverse display, normal display, and 8 second reverse display. Three types of information can be transmitted to employees.

  Furthermore, a code indicating the state of the elevator may be displayed alternately with the floor. For example, “S” is set as the code indicating that the service is disabled, and “C” (FIG. 4) is set as the code indicating that the notification to the maintenance company has been completed, and “5”, “S”, “C” are set. By switching the display in this order, it is possible to communicate to the maintenance staff that the service is not possible and that the notification to the maintenance company has been completed while it is stopped on the fifth floor. Also, the code size may be reduced and a plurality of codes may be displayed simultaneously.

  Furthermore, the display by the floor indicator may be a flicker (flashing) display at a speed corresponding to the state of the elevator. For example, in state A, flicker is displayed for 10 seconds at intervals of 0.1 seconds, in state B, flicker is displayed for 10 seconds at intervals of 0.5 seconds, and in state C, flicker is displayed for 10 seconds at intervals of 1.0 seconds. If it is set in advance, the maintenance staff can easily understand the state of the elevator related to the automatic diagnosis operation. When a plurality of pieces of information are transmitted, the above-described flicker display with different speeds may be sequentially performed every predetermined time.

  Further, by turning on, turning off, or blinking the light emitters (dots) 9a at the predesignated position of the floor indicator or the row of the predesignated light emitters 9a corresponding to the state of the elevator, Can communicate status.

  The display time (period) by the notification device 9 as described above can be set in advance. For example, when the normal service is possible, the display is performed for a predetermined time (for example, 5 hours) after the earthquake is detected, and the display of the automatic diagnosis related information is ended after the predetermined time has elapsed. Thereby, the trouble of switching display contents can be omitted.

  On the other hand, when the service is not possible or an abnormality of the device is detected, the display of the automatic diagnosis related information is continued until the maintenance engineer performs inspection and then switches. In this case, the display contents cannot be switched by a simple operation such as power ON / OFF until the operation is switched by a special operation of a switch provided on the operation panel in the car or the control panel or an operation from the maintenance tool 14.

  Next, FIG. 5 is a flowchart showing an example of the operation after the earthquake detection of the diagnostic operation control unit 11 of FIG. When an earthquake of a predetermined level or higher is detected by the Meteorological Agency earthquake information or the earthquake detector 2, the elevator control device 1 performs an earthquake control operation (step S1). Then, earthquake information including the earthquake occurrence time and detection level is recorded (step S2). Thereafter, a notification to the remote monitoring device 12 of the maintenance company monitoring center (step S3) and a notification by the notification device 9 (step S4) are performed.

  After the control operation at the time of the earthquake is finished and the shaking due to the earthquake is stopped, the automatic diagnosis operation is started (step S5), and the notification by the notification device 9 is performed (step S6). Here, as the automatic diagnosis operation, a plurality of diagnosis operations A to N that are different in traveling speed, traveling direction, inspection items, and the like are performed (step S7). When all the diagnostic operations A to N are normally completed, the operation of the elevator is resumed (step S8). However, if even one of the diagnostic operations A to N cannot be completed normally, the automatic diagnostic operation is interrupted and the operation of the elevator is suspended.

  When the automatic diagnosis operation ends, automatic diagnosis history information including progress information and result information is notified by the notification device 9 (step S10) and transmitted to the remote monitoring device 12 (step S).

  Note that the timing and number of notifications to the maintenance company monitoring center and the timing and number of notifications by the notification device 9 are not limited to the above example, but may be performed more frequently or periodically at a predetermined cycle. Or may be carried out.

  FIG. 6 is an explanatory diagram showing an example of automatic diagnosis history information managed by the diagnostic operation control unit 11 of FIG. In this example, the floor corresponding to the car position, the running / stopped state, the running direction, the car absolute position, and the event contents are recorded at a predetermined cycle.

  In the elevator control system as described above, the automatic diagnosis-related information is notified by the notification device 9, so that information relating to automatic diagnosis operation can be promptly transmitted to the user and maintenance personnel. Thereby, a sense of security can be given to the user.

  For example, if automatic diagnosis-related information is displayed on a display device at a hall on the entrance floor of a building, the maintenance staff can check the status of the elevator without getting on the elevator, and the inspection time can be reduced. Furthermore, if automatic diagnosis-related information is displayed on the display device at the hall that can be seen from the entrance of the building, the maintenance staff can check the status of the elevator without entering the building. In this way, by reducing the inspection time per elevator, when it is necessary to inspect more elevators due to an earthquake, more elevators can be inspected promptly and effective. is there.

Furthermore, since the diagnosis operation control unit 11 automatically transmits the automatic diagnosis related information to the remote monitoring device 12, the maintenance company monitoring center can quickly grasp the status of the automatic diagnosis.
Furthermore, the remote monitoring device 12 can transmit at least a part of the automatic diagnosis related information to the communication terminal 13 in response to a request from the communication terminal 13, so that the maintenance contract customer manages the status of the elevator managed by the remote monitoring device 12 Can be confirmed in a timely manner. Accordingly, it is possible to reduce inquiries from maintenance contract customers by telephone to the maintenance company, and to suppress the occurrence of congestion on the telephone line of the maintenance company.

Further, since the remote monitoring device 12 determines whether or not the automatic diagnosis related information can be transmitted to the communication terminal 13 based on the identification information received from the communication terminal 13, the automatic diagnosis related information flows out to a third party. Can be prevented and security can be ensured.
Furthermore, it is possible to input maintenance personnel information to the remote monitoring device 12, and since the remote monitoring device 12 transmits the input maintenance personnel information to the diagnostic operation control unit 11, it corresponds to the situation of the elevator. The response on the maintenance company side can be easily confirmed on the building side where the diagnostic operation control unit 11 is installed.
Furthermore, since the diagnostic operation control unit 11 causes the notification device 9 to notify maintenance personnel information, the maintenance company side can be informed to the user.
