Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator abnormality notification system for notifying a remote central monitoring center of the occurrence of an abnormality.

0002

[Prior Art] For example, as shown in Japanese Patent Application Laid-Open No. 193873/1987, an elevator is equipped with an abnormality detector such as an abnormality detector such as an abnormality detecting a situation such as an unusable state or a passenger being trapped in a car. A central monitoring center is provided with central monitoring equipment located remotely and connected to a number of elevators. An automatic telephone device is disposed between the abnormality detector and the central control device.

[0003] Conventional elevator abnormality notification devices are configured as described above, and when a failure occurs in one of the elevators and the abnormality detector of that elevator is activated, this operation is communicated to the central supervisory system via an automatic telephone device. will be notified. Then, based on the notification, the malfunctioning elevator is repaired by maintenance personnel.

0004

[Problem to be Solved by the Invention] In the conventional elevator abnormality alarm system as described above, it is conceivable that an abnormality occurs in each of a large number of elevators during an earthquake. There was a problem in that the receiving line of the central monitoring device became congested due to its operation, making it impossible to receive data.

[0005] This invention was made in order to solve such problems, and an object of the present invention is to obtain an elevator abnormality notification device that alleviates the situation in which reception is not possible due to the simultaneous operation of abnormality detectors when an earthquake occurs. do.

[0006]

[Means for Solving the Problems] An elevator abnormality notification means according to the present invention includes a first timer, a second timer, and a control device set for an elevator group consisting of a plurality of elevators installed in a building. Anomaly detectors are installed in the equipment, each elevator, and an earthquake detector near the building.

[0007]

[Operation] In the elevator abnormality notification system constructed as described above, the control device is energized by the operation of one of the abnormality detectors and the earthquake detector. Then, after the time limit of the first timer has elapsed, an abnormality notification operation is performed on the central control device, and if this abnormality notification has not been received, an abnormality re-alarm operation is performed after the timer limit of the second timer device has elapsed.

[0008]

[Example] Example 1. 1 and 3 are diagrams showing one embodiment of the present invention, and in the diagrams, 1 is a building in which an elevator group 2 is installed, 3 -
5 are elevators forming elevator group 2,
3 is machine A, 4 is machine B, and 5 is machine C. 6 is an earthquake detector installed at a suitable location in the building 1, 7 to 9 are detectors installed in each elevator and operate by detecting abnormalities such as rail derailment, 7 is an abnormality detector for Unit A 3, Reference numeral 8 indicates an abnormality detector of the B-unit machine 4, and 9 indicates an anomaly detector of the C-unit unit 5.

Reference numerals 10 to 12 are timer devices each set to a predetermined time limit for the elevator group 2; 10 is a first timer device, 11 is a second timer device, 12 is a third timer device, and 13 is a second timer device.
is an elevator control panel connected to each elevator of elevator group 1. 14 is a control device having an abnormality notification program, and includes an I/0 port 14a, a RAM 14b, and a C
Computer 1 equipped with PU14c and ROM14d
4e. 15 is a central control device installed in a central control center (not shown) remote from the building 1 and connected to the elevator group 2 and many other elevators (not shown).

The operation of the elevator abnormality notification device configured as described above will be explained with reference to the flowchart shown in FIG. That is, if the elevator control panel 13 is activated and the elevator is in operation, steps 101 to 10 are performed.
The process proceeds to step 2, and if an earthquake occurs and the earthquake detector 6 is activated, the process proceeds to step 103. In step 103, if the abnormality detector 7 of the A machine is activated, the process proceeds to step 106; otherwise, the process proceeds to step 104. In step 104, if the abnormality detector 8 of the B machine is activated, the process proceeds to step 106; otherwise, the process proceeds to step 105. If the abnormality detector 9 of the C machine is activated in step 105, the process advances to step 106. Step 1
In 06, the first timer 10 set for the elevator group 2 is energized and when the first predetermined time has elapsed, the process proceeds to step 107, and the control device 14 detects the occurrence of an abnormality in at least one of the elevators A to C 7 to 9. is reported to the central control device.

[0011] Therefore, although it is conceivable that abnormalities occur in a large number of elevators at once due to an earthquake, in this case, only one elevator in elevator group 2 will be notified of an abnormality, so congestion in the receiving line will be alleviated. be done. Furthermore, the abnormality alarm is issued after a first predetermined time period appropriately set for each elevator group such as elevator group 2, that is, with a time difference for each elevator group. This makes it easier to receive abnormality alerts when an earthquake occurs. It is also possible to set a short first predetermined time limit in an elevator in a building with a high repair priority, such as a hospital, so that the signal can be received early and repaired urgently.

[0012] Then, from step 107 to step 10
If the alarm has not been delivered, the process proceeds to step 109, where the second timer 11 appropriately set for each elevator group such as elevator group 2 is activated, and when the second predetermined time period has elapsed, the process returns to step 107. Abnormality is re-reported. Therefore, the congestion of the receiving line at the time of abnormal re-reporting is alleviated.

In step 102, if the earthquake detector 6 does not operate, the process proceeds to step 110; if the A unit and abnormality detector 7 do not operate, the process proceeds to step 112; if they do, proceed to step 111, and the control device 14 is activated. The abnormality of machine A is reported to the central control device 15 via the central control device 15. Then, the process proceeds to step 112, and if the B unit abnormality detector 8 does not operate, the process proceeds to step 114, and if there is an operation, the process proceeds to step 113, where the abnormality of the B unit is reported to the central control device 15 via the control device 14. . Next, the process proceeds to step 114, and if the unit C abnormality detector 9 does not operate, the process proceeds to step 116.
If there is an operation, the process advances to step 115, and the abnormality of machine C is reported to the central management device 15 via the control device 14. Then, proceed to step 116, and if the notification is not delivered, step 1
The process proceeds to step 17, where the third timer 12 appropriately set for each elevator group such as elevator group 2 is energized, and after the third predetermined time period has elapsed, the process proceeds to step 118. Step 118
The abnormality is re-reported at step 116, and the process is repeated until the alarm is transmitted. This makes it easier to receive abnormality notifications when abnormalities occur frequently at the same time other than during earthquakes.

[0014]

[Effects of the Invention] As explained above, the operation of the abnormality detector and earthquake detector of one of the elevators in the elevator group causes an abnormality to be generated in the central control device after the first predetermined time period set for the elevator group. If the alarm is not delivered, the abnormality is re-reported after a second predetermined time period set for the elevator group. This has the effect of reducing the number of abnormality alerts issued during an earthquake, and providing a time difference between abnormality alerts and facilitating the reception of abnormality alerts.
