Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an inspection device for an elevator control device.

[Conventional technology]

In the event of an earthquake, fire, etc., the elevator will carry out control operations to rescue passengers in the car. By the way, conventionally, in order to confirm whether or not the control operation is normally performed, one maintenance staff artificially generates an emergency state such as an earthquake or a fire in the elevator machine room,
One other maintenance staff boarded the car to check if the control operation was normally performed. For example, in the case of control operation by simulating an earthquake, the car is the I was making sure to stop at the floor. As described above, at least two maintenance personnel are required to confirm the known control operation.

On the other hand, there is an attempt to reduce the number of maintenance personnel required for confirmation of control operation, for example, Japanese Patent Laid-Open No. 58-1576.
As disclosed in Japanese Patent Publication No. 85, a signal simulating an emergency condition such as an earthquake or a fire is generated, this output is input to the car control device, the car is controlled, and the failure diagnosis device controls the control operation. An inspection device has been proposed that automatically diagnoses whether or not it is operating normally.

[Problems that the device tries to solve]

In the above conventional inspection device, the former method is labor-intensive and requires a large labor cost, and the latter method requires a new failure diagnosis device and this input / output device, which makes the device complicated and costly. There was a problem of becoming expensive.

The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide an inspection device for an elevator control device that is inexpensive and does not require manpower.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides an elevator control device for activating an elevator car control device to shift a car to a predetermined control operation when an emergency condition such as an earthquake or a fire is detected. An inspection switch arranged in the room, and signal input means for operating after a first time from operating the inspection switch to input a simulated signal simulating the occurrence of the earthquake, fire or the like to the car control device. ,
And a signal cut-off means for stopping the input of the simulated signal to the control device of the car after a second time from the operation of the signal input means, and one maintenance person operates the inspection switch during the first time. After the operation, it is a time equivalent to moving into the car, and the second time is for the one maintenance person to confirm the operation of the control device of the car in the car. Equipped with means chosen to be a comparable time.

[Action]

According to the means, the maintenance person first operates the inspection switch in the elevator machine room, and then, at the timing when the maintenance person gets into the car, the simulated signal simulating the emergency state is the control device for the car. Entered in. At this time,
The maintenance personnel confirms whether or not the control operation of the car is normally performed while riding on the car, and at the timing when the confirmation is finished, the simulation input to the control device of the car The signal is cut off, and the control operation of the car is automatically canceled. As described above, the confirmation test of the operation of the control device of the car can be performed by only one maintenance person, and the confirmation test does not require any expensive test device.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

The figure shows the electric circuit diagram of the inspection device according to the present invention. P and N are DC power supply terminals, A is an earthquake detector, A _a is its a contact, 1 is an earthquake control device, and 2 is a machine room. It is an inspection switch provided in. 3R is a relay that is energized when the inspection switch 2 is operated, and 3R _a1 and 3R _a2 are the a
The contact 3R _b is the b contact. 4 is a timer that is, the signal input means is biased counted after a predetermined time, for example after 5 minutes from the time of contact 3R _a2 is closed, 4 _a1, 4
_a2 is the a contact. When the contact _4a1 is closed, a simulation signal for operating the seismic control device 1 is input. 5
Is a timer or signal interrupting means that starts counting when the contact _4a2 is closed and is energized after a predetermined time, for example, 10 minutes, and 5b is its b contact. A signal generating means 3 for generating a simulated signal equivalent to an earthquake by using the inspection switch 2, the signal input means 4, the signal blocking means 5, etc. described above.
Is configured.

Next, the operation of the present invention will be described.

Now, when the maintenance person operates the inspection switch 2 in the machine room, the circuit of P-2-5b-3R-N is formed, and the relay 3
R is energized, the relay 3R is self held by the contact _{3R a1,} close contact _{3R a2} is, signal input means 4 starts counting.

The maintenance staff leaves the machine room and rides a car (not shown). The signal input means 4 is energized after a first time, for example 5 minutes, the contact _4a2 is closed and the signal interruption means 5 starts counting.
Further, since the contact _{4a1 is} also closed, a circuit of P- _4a1-1 -N is formed, a simulated signal is input, the seismic control device 1 is activated, and seismic control operation is performed. For example, the seismic control light in the car is turned on, the car is stopped at the nearest floor, the door is opened, the door is closed after a predetermined time, the light is turned off, and the car waits on that floor. A second time indicating the timing at which the control operation ends,
For example, after 10 minutes, the signal interruption means 5 is energized and the contact 5
b is opened, the relay 3R is deenergized, and the initial state is restored.

It should be noted that, during the relay 3R is energized to open the contact 3R _b, contact A
It is set so that _a is invalid.

According to the present embodiment, by providing the signal input means 4 for generating a simulated signal equivalent to an earthquake, the inspection switch 2, etc., only one maintenance person can inspect the seismic control system.

Although the above-described embodiment has described the case of the seismic control operation, the fire control operation can be similarly tested by using the fire control device instead of the seismic control device.

[Effect of device]

According to the present invention, the inspection switch disposed in the elevator machine room and the inspection signal that operates after a first time from the operation of the inspection switch are input to the car control device by simulating the occurrence of an earthquake, fire, or the like. And a signal cutoff means for stopping the input of the simulated signal to the control device of the car after the second time from the operation of the signal input means. It is the time equivalent to moving into the car after operating the inspection switch, and the second time is equivalent to the one maintenance worker performing a confirmation test of the operation of the car control device in the car. Since it is chosen to be the time to do, only one maintenance person can carry out a confirmation test of the operation of the elevator control device, and the number of people for this confirmation test can be confirmed by this kind of confirmation so far. Significantly compared to the test It is possible to Gensa. Further, it is possible to perform a confirmation test of the operation of the elevator control device without using an expensive failure diagnosis result, and it is possible to obtain an inexpensive inspection device for the elevator control device having a simple structure. .
