This state is continued until an earthquake control release motion is effected by means of the switch 14.

Description

[Detailed description of the invention] [Object of the invention] (Industrial application field) The present invention enables seismic control operation of an elevator,
The present invention relates to an elevator control device that can remotely release the activated earthquake sensing means from an elevator monitoring panel or the like after an inspection operation.

(Prior art) Conventionally, earthquake control operations using earthquake sensors have been
It has been generalized as described in related laws, JEAS published by the Elevator Association, and specification manuals published by various ministries and agencies. There are three types of earthquake detectors: extra low gal earthquake detectors that can set extra low gal values, low gal earthquake sensors that can set low gal values, and high gal earthquake sensors that can set high gal values. The elevator control device is equipped with at least two of these, an extra low gull earthquake sensor and a low gull earthquake sensor.

The control system for elevators equipped with special low-gal earthquake sensors is
When the special low gal earthquake sensor operates (including longitudinal wave detection),
After the car stops at the nearest floor, the earthquake sensor is automatically canceled (reset) after a certain period of time has elapsed, and the car returns from earthquake control operation to normal operation.

In addition, the control device for an elevator equipped with a low-gal earthquake sensor is designed so that when the low-gal earthquake sensor is activated, a running car will stop at the nearest floor, and a stopped car will continue to be stopped. There is.

In addition, when the high-gal earthquake detector is activated, the elevator control device equipped with a high-gal earthquake sensor will forcibly stop a car in an express zone, etc., or a car that is stopped due to a power outage, and will notify the manager on the monitoring panel side. etc. closes the earthquake low-speed switch, and at the same time asks the passengers inside the car to continue pressing the door close switch, the car is driven in the direction away from the counterweight to rescue the passengers inside the car. In this way, even if the earthquake sensor is activated, the car is stopped at the nearest floor to ensure the safety of the passengers inside the car, thereby preventing secondary disasters.

In this case, if the earthquake is greater than a preset low gal value, all the cars are stopped at the nearest floor. After the earthquake has calmed down, the earthquake detectors are deactivated after the cars are inspected and operated. To the room,
Since you may have to walk around using the stairs, if there are multiple elevators or in a location with a high number of floors, deactivate the earthquake detector and return the elevators to normal operation. may take a long time.

(Problem to be Solved by the Invention) As described above, in the conventional elevator control device, when the earthquake sensor operates and reaches a low gal value or a high gal value, the earthquake sensor itself is canceled. Because the elevators do not work at all, people who maintain the elevators have to walk up the stairs, and when there are multiple elevators, they have to walk to each machine room to disable the earthquake detectors.
Alternatively, the administrator is in trouble, and it takes a considerable amount of time to get the elevator back into normal operation.

Therefore, even if the earthquake sensor is activated, the present invention enables inspection operation by remote control without having to go to the machine room where it is installed, and then cancels the earthquake control operation.
Furthermore, it is an object of the present invention to provide an elevator control device that can return to normal operation by canceling earthquake control No. 73 for each elevator.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention is provided with an earthquake sensing means, and when the earthquake sensing means detects an earthquake of a low gal value or higher, the elevator operation device In an elevator control device in which a normal operation command given to an elevator is switched to an earthquake control operation command, an elevator control panel is installed on an elevator monitoring panel side that is separate from a machine room housing the elevator operation device. An inspection operation means for giving an inspection command and a direction specifying means for giving a driving direction command are provided,

The earthquake tube 1. It is equipped with an earthquake control operation cancellation means for canceling the I operation.

(Function) According to the present invention, since the inspection operation means and the car operation direction designation means are disposed on the elevator monitoring panel side, when the earthquake detection means is activated and the earthquake control operation is started, an earthquake occurs. After completion, at the discretion of the manager, etc., close the inspection operation means and the car operation direction designation means to check and confirm the condition of the hoistway and elevator, especially when there is no problem in restarting the elevator. Under the condition that the earthquake detector with a low gal value or higher is activated, and after completing manual operation and after a certain period of time, Jt! ! The earthquake control operation can be canceled by the earthquake control operation cancellation f stage. Therefore, even if the earthquake sensor is activated, you do not have to go to the machine room where it is installed (but you can perform inspection operation by remote control, and then cancel the earthquake control operation, and also cancel the earthquake control signal for each elevator. It is possible to return to normal operation.

It has an a contact 11a and a b contact 11b that interlock with each other, and when the contact 5a2 is closed by the operation of the low gal action keep relay 5, the contact 11a is closed and the contact 11b is opened during inspection operation. , to raise the car and perform a check operation. The low gal operation lowering switch 12 has an a contact 12a and a b contact 12b that are interlocked with each other, and when the contact 5a2 is closed by the operation of the low gal operation keep relay 5, the contact 12a is closed during inspection operation. , and by opening the contact 12b, the car is lowered to perform a checking operation. The earthquake control release switch 14 is pressed to cancel the earthquake control operation, and thereby only the designated elevator is released from the earthquake control operation. The above-mentioned low gal operation inspection switch 10, low gal operation up switch 11, and low gal operation down switch 12
and the earthquake control release switch 14 are both provided within the elevator monitoring panel.

The earthquake control inspection relay 15 has an a contact 15a1 and an a contact 15a2, and is energized when the changeover contact 10'c of the inspection switch 10 during low gal operation is switched to the a terminal, whereby the contacts 15a1, ”

is opened, and by opening the earthquake control release switch 14 with this contact 16b open, the earthquake control is released only for the specified elevator.

Di! The lil microprocessor 13 closes either the up switch 8 or the down switch 9 when the elevator inspection switch 7 is operated, the contact 7a is closed, and the changeover contact 7c is switched to the a terminal side. As a result, an inspection command is given to the elevator operating device located in the machine room (not shown).

Here, the operation of this embodiment configured as above will be explained. Now, when an earthquake occurs and the special low gal earthquake sensor 1 operates, the special low gal operation relay 3 is energized and the contact 3a is closed, and a signal is manually sent to the control microprocessor 13. An earthquake control command is given to the operating device of the elevator (not shown), and the running car decelerates to a stop at the nearest floor and waits for an arbitrary period of time.Then, after a certain period of time, the special low gal earthquake detector 1 will be automatically canceled.

In addition, when an earthquake occurs and the low gal earthquake sensor 2 is activated, the contact 4a is closed by the excitation of the low gal operation relay 4, and the low gal operation keep relay 5 is thereby energized and the contact 5al is closed. The control microprocessor 1 is then connected via the switch 14 and the contact 16b connected in parallel with the switch 14.

Since the earthquake control operation cancellation means consisting of the switch 14 is disposed on the monitoring panel side, the contact 5a2
is closed, by closing the contact 10a of the low gal operation check switch 10, the inspection operation state is entered.In this state, the low gal operation raise switch 11 or the low gal operation lower switch・By closing Sochi 12, the elevator can be raised and lowered for inspection operation.

On the other hand, the aforementioned inspection suite! At the same time as the closing operation of -10, the earthquake control inspection relay 15 is energized and contacts 15a1.15
a2 is closed to form a self-holding circuit, and after completing the inspection operation, close the contact 10a of the inspection switch 10 and switch the changeover contact 10c to the terminal 8b. After an arbitrarily set time, the time relay for canceling earthquake control is activated. 16 is excited and the contact 16b operates to open the circuit. At this time, by pressing Earthquake control release switch 14, earthquake control will be canceled for only the specified elevator, and by registering a platform call, the elevator will be pulled to the destination floor, allowing the manager or maintenance person to quickly It is possible to go to the top floor and perform inspection operations in the event of an earthquake, as well as deactivate earthquake detectors 1 and 2.
