Detailed Description of the Invention [Industrial applications]

The present invention relates to a remote monitoring device for an elevator equipped with an earthquake detector, and more particularly to a remote monitoring device for an elevator that automatically notifies a maintenance center of the operation of the earthquake detector through a telephone line.

[Prior art]

As an earthquake countermeasure for an elevator, an earthquake control system has been established and widely used, when an earthquake of a certain level or more occurs, an earthquake detector operates to automatically stop the running elevator at the nearest floor. Therefore, an elevator equipped with an earthquake control system can safely stop when a wide-area earthquake with a seismic intensity of 4 to 5 occurs, for example, and the safety of the elevator against earthquakes can be improved. However, in the case of a wide area earthquake, it takes a lot of time to restore the operation of the elevator. In other words, an elevator having an earthquake control system does not have a function of diagnosing a failure that occurred during an earthquake even if it has a function related to earthquake detection. It is necessary to restore it after confirming safety. Therefore, when a large number of elevators existing in the area are stopped as in the case of a wide area earthquake, these cannot be restored in a short time. On the other hand, in the elevator earthquake restoration device disclosed in Japanese Patent Laid-Open No. 60-77081, various automatic inspection functions are added to the elevator, and when the building manager confirms that there is no abnormality in the building, etc. , It is possible to restore the elevator operation without waiting for the arrival of maintenance personnel. However, there is a problem that it takes a lot of money to make the automatic inspection function of the elevator equivalent to the inspection by the maintenance staff. Therefore, in order to shorten the elevator recovery time, a remote seismic control operation monitoring system as shown in FIG. 5 has been conventionally proposed. In FIG. 5, 1 is an earthquake detector that operates when an earthquake of a certain level or higher occurs, 2 is an elevator control device that performs seismic control operation and normal operation, and 3 is a telephone line 4 that indicates an earthquake occurrence.
This is an automatic telephone notification device for making a notification to the maintenance center 5 via. In the monitoring system configured as described above, the seismic detector 1 operates when seismic vibration of a level at which the elevator has to be stopped is detected, and the detection signal is the elevator control device 2.
And is output to the automatic telephone notification device 3. Upon receiving the earthquake detection signal, the elevator control device 2 performs the seismic control operation to automatically stop the elevator to the nearest floor. At the same time, the automatic telephone notification device 3 automatically notifies the maintenance center 5 via the telephone line 4 that the earthquake detector 1 has been activated. In this way, the operation of the seismic detector 1 in the elevator group is constantly monitored by the maintenance sensor so that the elevator operation can be restored early.

[Problems to be Solved by the Invention]

In the conventional elevator monitoring system as described above, the operating state of the seismic detector 1 is simply notified to the maintenance center by the telephone automatic notification device 3, so that the operating state of the seismic detectors at several locations can be checked. When receiving with 5, there is no problem. However, earthquakes that require elevators to stop are generally large and widespread, so
If the earthquake detectors 1 of many buildings in the earthquake area operate at the same time as the occurrence of the earthquake, the notifications to the maintenance center 5 will be concentrated in a short time. Is confused and expected to go down. In such a case, the elevator to which the seismic detector operates can be significantly delayed or cannot be notified to the maintenance center 5, and the elevator with the seismic detector can be detected at the maintenance center 5. There was a problem that the recovery of the elevator would be delayed significantly. The present invention has been made to solve the above-described problems, and with the occurrence of a large-scale wide area earthquake, it is possible to reliably detect the maintenance center without radiating the elevator where the earthquake detector operates, It is an object of the present invention to obtain an elevator remote monitoring device that enables early elevator restoration measures.

[Means for Solving the Problems]

The elevator remote monitoring device according to the present invention is a notification control for setting the priority of the notification to the maintenance center by changing the time from the operation of the seismic detector in the building in which each elevator is operated until the alarm is issued. It is equipped with means.

[Action]

If many earthquake detectors in the monitoring area of the maintenance center operate at the same time as an earthquake occurs, the alarms associated with those operations are prioritized by each alarm control means.
The operation of the seismic detector will be reported in order from the elevator with the highest priority, and the maintenance center will be notified. Therefore, according to the present invention, even if many earthquake detectors operate at the same time, the alarm sent to the maintenance center through the telephone line does not sound, and the elevator where the earthquake detector operates can be reliably detected. In addition to being able to do so, it becomes possible to restore the elevator early.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are block diagrams showing an embodiment of an elevator remote monitoring apparatus according to the present invention. In FIG. 1, the seismic detector 10 mechanically operates to close the contacts when seismic vibrations of a predetermined level or more at which the elevator should stop are generated, and the contact signal 10a is restored until artificially restored.
Will continue to be output. The seismic detector alarm controller 11 uses the contact signal 10 of the seismic detector 10.
Upon receiving a, the operation signal 11a of the earthquake detector 10 is output, and the delayed operation signal 11b of the earthquake detector 10 is output after a preset time delay. The delayed operation signal 11b of the seismic detector 10 is used to set a priority when the seismic detector 10 of the monitored elevator operates and automatically notifies the maintenance center through a telephone line. It is determined by the location conditions of elevators in the area, the structure of buildings and traffic conditions. For example, in the case of location conditions, priority is given to an elevator located in the management area of the maintenance center that takes a longer time for a maintenance worker who is far from the maintenance center to arrive. When setting according to the building structure, etc., give priority to those that are prone to property damage due to floor height, rigid / flexible structure. When setting according to the traffic conditions, priority is given to the size of the building, the number of elevators, and the normal operation rate, whichever is more affected by the suspension of the elevator due to the earthquake. In FIG. 1, when the elevator controller 12 receives the seismic detector operation signal 11a from the seismic detector alarm controller 11, the elevator controller 12 controls the elevator to stop at the nearest floor, and then the elevator automatically operates until the safety inspection ends. Various operation monitor signals 12a related to elevator operation that prevent startup
Is output. Further, the signal selector 13 selectively takes in the operation monitor signal 12a and the delayed seismic detector operation signal 11b, converts it into a signal for line transmission, and outputs it. The automatic telephone device 14 transmits the signal output from the signal selector 13 to the receiving device 16a of the maintenance center 16 via the telephone line network 15 by automatic dialing. , And the telephone line network 15 and the maintenance center 16 are connected by telephone lines 17 and 18, respectively. Furthermore, the uninterruptible power supply 19 supplies power to the earthquake detector alarm controller 11 and the signal selector 13 without interruption. FIG. 2 is a detailed diagram of the internal configuration of the seismic sensor alerting controller 11. The seismic sensor alerting controller 11 includes a signal converting circuit 111, a counting circuit 112, a clock generating circuit 113, a time setting circuit 114 and It consists of AND gate 115. The signal conversion circuit 111 receives the contact signal 10a from the seismic detector 10 and converts it into an seismic detector operation signal 11a and a signal that also serves as an enable and alarm for the counting circuit 112.
11a is output from the output terminal A, and a signal also used for reporting is output from the output terminal B. Further, when a signal from the B terminal of the signal conversion circuit 111 is input to the enable terminal E of the counting circuit 112, the counting circuit 112 counts the clocks that are significant and is input from the generation circuit 113 to the clock terminal C, and the count is calculated. When the numerical value reaches the set value applied from the time setting circuit 114 to the load terminal L, a counting completion signal is output from the Q terminal to the AND gate 115 to gate the AND gate 115, and the B terminal of the signal conversion circuit 111 is output. The output signal is sent as the delay operation signal 11b. The time setting circuit 114 is used by the maintenance center 16 when the seismic detector operates.
When the alarm is sent to the elevator, the priority is determined so that the alarm does not radiate on the transmission line with the alarm associated with the operation of the earthquake detector of other elevators, and the delay time for determining the priority is It is set by a switch circuit or a memory circuit. Next, the operation of this embodiment configured as described above will be described. When the earthquake detector 10 operates due to earthquake vibration of a predetermined level or higher, the contact signal 10a is output.
Signal conversion circuit 111 of the seismic sensor alerting controller 11
Outputs an earthquake detector operation signal 11a to the elevator controller 12. Upon receiving this, the elevator control device 12 performs seismic control operation such as stopping the elevator at the nearest floor. On the other hand, when the signal output from the B terminal of the signal conversion circuit 111 is input to the enable terminal E of the counting circuit 112, the counting circuit 112 starts counting. When the count value reaches the set time set by the time setting circuit 114, Q
The output becomes "H", and thereby the AND gate 115 is gated. Therefore, the signal output from the B terminal of the signal conversion circuit 111 is delayed by the set time set by the time setting circuit 114, and then the signal selector 13 outputs the delayed operation signal 11b.
Is output to. In the signal selector 13, the delay operation signal 11b is converted into a signal for telephone line transmission and output to the automatic telephone device 14. The automatic telephone device 14 establishes a data ring with the maintenance center 16 through the telephone line network 15 by automatic dialing,
As a result, the delayed seismic detector operation signal 11b is transmitted to the maintenance center 16 through the telephone line network. In addition, the earthquake detector alarm controller 11 and the signal selector 13,
Since power is supplied from the uninterruptible power supply 19, even if there is a power failure immediately after the occurrence of an earthquake, the operation of the earthquake detector can be reliably notified to the maintenance center 16. Further, the occurrence of a power failure is monitored by the signal selector 13 because an abnormality occurs in the operation monitor signal 12a of the elevator control device 12, so the power failure information can also be reported to the maintenance center 16. In the above-described embodiment, the seismic detector 10 of each elevator installation building existing in the monitoring area of the maintenance center 16 is installed.
The time from when the alarm is activated until the alarm is issued is set by each earthquake detector alarm controller 11, which gives priority to the alarms sent from the elevator installation buildings to the maintenance center 16 Since the structure is such that the red alarms are issued in sequence, many seismic detectors 10
Can be performed without noise even if the maintenance center 16 operates, and the elevator where the seismic detector operates can be reliably detected remotely. Then, since the earthquake detector operation is reported to the maintenance center in order from the building that needs to be restored sooner, the elevator can be restored quickly and the reliability of remote monitoring of the elevator via the telephone line can be improved. Will be improved. 3 and 4 show another embodiment of the elevator remote monitoring apparatus according to the present invention. FIG. 3 shows the overall configuration, and FIG. 4 shows the details of the seismic sensor alarm controller 11A. It is a block diagram shown. In the figure, the same parts as those in FIG. 1 and FIG. 2 are designated by the same reference numerals, the description thereof will be omitted, and different parts will be mainly described. The earthquake detector alarm controller 11A includes an alarm delay time counting circuit 112.
Has a time setting memory 116 for storing the set value of, and this memory 116 is composed of a non-volatile memory such as an E ² PROM, and the time data stored therein can be written from the maintenance center 16. For this reason, the maintenance sensor 16 is a transmission / reception device 16 capable of transmitting / receiving a signal to / from the automatic telephone device 14 of each building in the monitoring area.
The transmission / reception device 16b is provided with b, and the time data for the notification delay is converted into a signal for the telephone line, and the telephone line network is provided.
The signal can be transmitted to the automatic telephone device 14 of each building through 15 and the signal received by the automatic telephone device 14 is output to the signal selector 13. The signal selector 13 is an automatic telephone device 14
To selectively output the received signal from the signal decoder 20. The signal decoder 20 decodes the received signal and converts it into time data 20a for delaying the notification. This time data 20a is written in the time setting memory 116. In the above embodiment, the time from the operation of the seismic detector until the alarm is issued can be automatically set by the maintenance center 16. Along with this, when changing the restoration system in case of an earthquake due to an increase in the number of elevators in the maintenance area of the maintenance center, the maintenance center 16 side can quickly set the alarm delay time for each elevator. The burden on is greatly reduced.
