Abstract

PURPOSE:To detect elevator the earthquake sensors of which are worked without congestion by providing an alarming control means which differs a time between operation of the earthquake sensor of a building where elevators are built and alarming and sets a priority order of alarming to a maintenance center. CONSTITUTION:When an earthquake sensor 10 is operated by earthquake vibration of a given level or more, a circuit 111 of an earthquake sensor alarming control device 11 receiving a contact signal 10a from the earthquake sensor outputs an earthquake sensor operation signal 11a to a control device 12. Meanwhile, when a signal from a terminal B of the circuit 111 is inputted to an enable terminal E of a circuit 112, the circuit 12 starts to count. When a counting value attains a set time set by a circuit 114, an output Q is increased to H to gate an AND gate 115. Thereby, after an output signal from the terminal B of the circuit 111 is delayed for a set time set by the circuit 114, it is outputted as a delay operation signal 11b to a signal selector 13, where it is converted into a signal for a telephone circuit transmission and transmitted to a maintenance center 16.

Description

[Detailed description of the invention] [Industrial Icheon field]

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

[Conventional technology]

As an earthquake countermeasure for elevators, an earthquake control system has been established and widely used, in which when an earthquake of a certain level or higher occurs, an earthquake detector is activated to automatically stop the elevator in progress at the nearest floor. Therefore, an elevator equipped with an earthquake control system can safely stop when a wide area jtli with a seismic intensity of about 4 to 5 occurs, thereby improving the safety of the elevator against earthquakes. However, in the case of a wide-area earthquake, it takes a lot of time to restore elevator operation. In other words, even though elevators with earthquake control systems have functions related to earthquake detection, they do not have the function to diagnose failures that occur during earthquakes. It is necessary to restore the system after confirming its safety. For this reason, when a large number of elevators in a region stop, such as during a wide-area earthquake, it is not possible to restore them in a short time. On the other hand, in the old elevator station gtx device disclosed in Japanese Patent Application Laid-Open No. 60-77081, various automatic inspection functions are added to the elevator. When the system is approved, it is possible to restore elevator operation without waiting for maintenance personnel to arrive. However, there is a problem in that it requires a large amount of cost to make the automatic inspection function of the elevator equivalent to the inspection performed by maintenance personnel. Therefore, in the past, a remote earthquake control operation monitoring system as shown in FIG. 5 has been proposed in order to shorten the elevator restoration time. In Figure 5, 1 is an earthquake sensor that activates when an earthquake of a certain level or higher occurs, 2 is an elevator control device that performs earthquake control operation and normal operation, and 3 is an earth! This is an automatic telephone notification device that notifies the maintenance center 5 of the occurrence of t via the telephone line 4. In the monitoring system configured as described above, the ground insulator 1 operates when it detects seismic vibration at a level that requires stopping the elevator, and the detection signal is sent to the elevator control system N.
2 and the automatic telephone notification device 3. Upon receiving the earthquake detection signal, the elevator control device M2 performs earthquake control operation to automatically stop the elevator at the nearest floor. At the same time, the automatic telephone notification device 3 automatically reports to the maintenance center 5 via the telephone line 4 that the earthquake sensor 1 has been activated. In this way, the maintenance center constantly monitors the operation of the earthquake sensing ls1 of the elevator group, in order to restore operation of the elevators at an early stage.

[Problem to be solved by the invention]

In the conventional elevator monitoring system as described above, the operating state of the jllllt sensor 1 is simply notified by the automatic telephone notification device 3.
Since the information is only automatically reported to the maintenance center, there is no problem when the maintenance center 5 receives the operating status from the earthquake sensors at several locations. However, since earthquakes that require elevators to be stopped are generally large in scale and spread over a wide area, if the earthquake detection Wi 1 of many buildings in the earthquake area activates at the same time as the earthquake occurs, the notification to the maintenance center 5 can be made in a short time. As a result, it is expected that the processing capacity of telephone exchanges will be exceeded, leading to confusion and downtime of telephone lines. In such a case, the notification to the maintenance center 5 of the elevator whose earthquake sensor has activated may be significantly delayed or may become impossible to report, and the maintenance center 5 may not be able to detect the elevator whose earthquake sensor has activated. There was a problem that the restoration of the elevator was significantly delayed. This invention was made in order to solve the above-mentioned problems.In the event of a large-scale, wide-area earthquake, it is possible for a maintenance center to reliably detect an elevator in which an earthquake sensor has activated without causing any disturbance. The object of the present invention is to obtain a remote monitoring device for an elevator that enables early elevator recovery mW.

[Means to solve the problem]

The remote monitoring device for elevators according to the present invention sets a priority order for issuing alarms to the maintenance center by setting a priority order for issuing alarms to the maintenance center by setting different times from when the earthquake detectors of the building in which each elevator is installed to when an alarm is issued. It is equipped with information control means.

[Effect]

When many earthquake detectors within the monitoring area of the maintenance center operate at the same time as an earthquake occurs, the alarms associated with the operation are prioritized by each alarm control means.
From the elevator with the highest priority to the ground! The operation of the I sensor will be reported and the maintenance center will be notified. Therefore, in this invention, even if many earthquake detectors operate at the same time, the alarms sent to the maintenance center through the telephone line will not be overloaded, and the elevator in which the earthquake detector has operated can be reliably detected. Not only can it be detected, but it can also be used to quickly restore the elevator. It becomes possible.

【Example】

Embodiments of the present invention will be described below based on the drawings. FIGS. 1 and 2 are block diagrams showing an embodiment of an elevator remote monitoring device according to the present invention. As shown in Figure 1, the seismic sensor 1O mechanically operates to close the contacts when seismic vibration exceeding a predetermined level at which the elevator should be stopped continues to output the contact signal 10a until the elevator is manually reset. It is. The earthquake sensor alarm controller 11 receives the contact signal 10a of the earthquake sensor Is10, outputs the operation signal 11a of the earthquake sensor 10, and also outputs the earthquake sensor v after a preset time delay.
A delayed operation signal 1lb of s10 is output. The delayed operation signal 1lb of the earthquake detection@10 is used to set the priority when automatically reporting this to the maintenance center through the telephone line when the earthquake detection N10 of the monitored elevator operates. It is determined by the location of the elevator within the building, the structure of the building, traffic conditions, etc. That is, in the case of location conditions, priority is given to elevators located within the management area of the maintenance center that are far away from the maintenance center and take time Cζ for the maintenance worker to arrive. When setting according to building structure, etc., prioritize buildings that are likely to cause property damage due to floor height and rigid/flexible structure. When setting according to traffic conditions, priority is given to buildings that are more likely to be affected by elevator suspension due to an earthquake, based on the size of the building, the number of elevators, and the normal operating rate. In FIG. 1, an elevator system 11111112 is an earthquake sensor operation signal 11 from an earthquake sensor alarm controller 11.
When a is received, the elevator is controlled to stop at the nearest floor, and thereafter automatic start-up of the elevator is prevented until the safety inspection is completed, and various continuous monitor signals 12a related to elevator operation are output. Further, the signal selection@13 selectively takes in the operation monitor signal 12a and the delayed earthquake sensor operation signal 1lb, converts it into a signal for line transmission, and outputs it. The own 6F4 talk device 14 transmits the signal output from the signal selector 13 to the receiving device 1'i6a of the maintenance center 16 via the telephone line network 15 by automatic dialing. 14 and the telephone line network 15,
A telephone line 17.1 is connected between the telephone line network 15 and the maintenance center 16.

It is composed of. The signal conversion circuit 111 inputs the contact signal 10a from the earthquake sensor IIr10 and converts it into an earthquake sensor operation signal 11a and a signal that also serves as an enable and alarm for the counting times Is112, and the operation signal 11a is output. A signal that also serves as an alarm is output from the terminal A and an output terminal B, respectively. Further, when the 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 become significant and is input to the clock terminal C from the generation circuit 113, and calculates the clock. The numerical value is the time setting circuit 11
When the set value applied from 4 to the load terminal L is reached, a counting completion signal is output from the Qm element to the 7th gate 115, and the 1st gate 115 is connected to the gate 1.
The signal output from the B terminal of No. 1 is sent out as a delayed operation signal 1lb. When issuing an alarm to the maintenance center 16 when the earthquake sensor is operating, the time setting circuit 114 prioritizes the alarm so that the alarm does not overlap with the alarm accompanying the earthquake detection US operation of other elevators. The delay time for determining the priority is set by a switch circuit or a memory circuit. Next, the operation of this embodiment configured as described above will be explained. When the earthquake sensor 10 is activated by seismic vibration of a predetermined level or higher, a contact signal 10a is output, so the signal conversion circuit 111 of the Earthquake Detection Alliance Notification Control@11 that receives this contact signal 10a converts the earthquake sensor operation signal into 11a is output to the elevator control device jigll2. Upon receiving this, the elevator control device 12 performs an earthquake 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 IIs 112, the counting circuit 112 starts counting. Then, when the counted value reaches the set time set by the time setting circuit 114, the Q output becomes rHJ, and thereby the AND gate 115 is gated. Therefore, the signal conversion circuit 1
The signal output from B@11 is the time setting times $11.
After being delayed for the set time set in 4, the delayed operation signal 1
It is output to the signal selector 13 as lb. signal selection vj
At 13, the delayed operation signal is converted into an 11-bit telephone line transmission signal 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, and thereby transmits the delayed earthquake sensor operation signal 1 lb to the maintenance center 16 through the telephone line network. do. In addition, since power is supplied to the earthquake detection M alarm controller 11 and signal selection @ 13 from the uninterruptible power supply 19, even if a power outage occurs immediately after an earthquake occurs, the operation of the earthquake sensor is sent to the maintenance center 16. Reports can be made with certainty. In addition, the occurrence of a power outage is monitored by the elevator control device 12, and the signal selector 1
3, the power outage information can also be reported to the maintenance center 16. In this embodiment as described above, the earthquake detection I of each elevator installed building existing within the monitoring area of the maintenance center 16 is
The time from when #10 operates until the alarm is issued is set by each earthquake sensor alarm controller 11, and this gives priority to the alarm from each elevator installation building to the maintenance center 16. Since the configuration is such that alarms are issued in the order of highest priority, even if many earthquake detection ILs 10 operate at the same time as an earthquake occurs in a large area, the alarms can be issued to the maintenance center 16 without any noise. As a result, elevators with activated earthquake sensors can be reliably detected remotely. Since the earthquake sensor operation is notified to the maintenance center in order starting from the building that requires the earliest restoration, it becomes possible to take early restoration measures for the elevator, and the reliability of remote monitoring of elevators through telephone lines is improved. It will improve. Figures 3 and 4 show other embodiments of the elevator remote monitoring device according to the present invention, with Figure 3 showing the overall configuration and Figure 4 showing details of the earthquake sensor alarm control WjllA. It is a block diagram. In this figure, parts that are the same as those in FIGS. 1 and 2 are given the same reference numerals, and their explanation will be omitted, and different parts will be emphasized. The earthquake sensor alarm controller 11A has a time setting memory 116 that stores the setting value of the alarm delay time counting circuit 112, and this memory 116 is composed of a non-volatile memory such as E2PROM, The time data can be written by the maintenance center 16. For this purpose, the maintenance center 16 is equipped with a transmitting/receiving device 16b capable of transmitting and receiving signals with the own IIIIT1 talk device 14 of each building within the monitoring area, and from this transmitting/receiving device 16b, time data for delaying alarms are sent. is converted into a signal for the telephone line and transmitted through the telephone line network 15 to the automatic telephone equipment 1 in each building.
It is now possible to send it to 4, and it is self! @The signal received by the telephone device 14 is output to the signal selector 13. The signal selector 13 selectively outputs the received signal from the self-a telephone device 14 to the signal decoder 20. The signal decoder 20 decodes the received signal and converts it into time data 20a for delaying the alarm. B's time data 20a is in the time setting memory 11
Written in 6 and 7l. In the above embodiment, the time from the operation of the earthquake sensor until the alarm is issued can be automatically set by the maintenance center 16. In line with this, when changing the recovery system in the event of an earthquake due to an increase in the number of elevators within the monitoring area of the maintenance center,
The maintenance center 16 resets the alarm delay time for each elevator.
This can be done quickly on the side, greatly reducing the burden on maintenance personnel.

As explained above, according to the present invention, the time elapsed from when the earthquake detectors of each building with elevators located within the monitoring area of the maintenance center are activated due to earthquake vibration of a predetermined level or higher until the maintenance center is notified is The alarm control means for each earthquake sensor is different, and the structure is configured so that the elevators in each building where the elevators are installed can prioritize the alarms sent to the maintenance center through the telephone line, starting with the elevator with the highest priority. Even if many earthquake detectors operate at the same time as an earthquake occurs, the alarm associated with the operation can be sent to the maintenance center without being overloaded, and the elevator in which the earthquake detector has operated can be reliably detected remotely. At the same time, there is an effect that the elevator can be restored at an early stage.
