Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for inspecting and operating an elevator.

It is well known that in the event of an emergency such as an earthquake, fire, or power outage, elevators are operated under controlled conditions in order to rescue passengers in the cars. The outline is shown in Figure 1.

In the figure, il+ is the fire control command switch installed on the staff control panel installed in the building's manager's room, (la) fl
When the fire control command switch (1) is turned on, the fire control command signal becomes rHJ, (2) is the earthquake sensor installed in the elevator machine room, (2a) is the earthquake sensor (21 is 8
Earthquake detection signal that becomes rHJ when an earthquake of 0 gal or higher is detected, (3) is a fire detector installed in the machine room or elevator hall, (3a) is a fire detector (3) that detects smoke or a temperature above a certain level. Fire detection signal that becomes rHJ when heat is detected, (
4 includes a control operation circuit (not shown) that manages the operation of the elevator car and performs control operation in the above-mentioned emergency, and is responsible for setting the driving direction, determining running and stopping, and commanding door opening and closing. , an attendant management board (1), a car management device that manages various functions such as displays on cars and landings, (4a) is an earthquake control light lighting signal, (4b) is a fire control light lighting signal, (4
C) is the control operation completion light lighting signal, (5) to (7) are the earthquake control light, fire control light and control operation circuit light installed on the staff management panel, (8) the height control device (command of 4+) This is a car control device that completely controls the operation of the car using VC.

In other words, when the earthquake sensor (2.80 kW or more) detects all earthquakes, the earthquake detection signal (2a) becomes rHJ, the control operation circuit in the management device (4) operates, and the earthquake control light lighting signal is activated. (4a) becomes rHJ. Now, the earthquake control light (5) lights up, fully indicating that earthquake control operation has started. Then, if the car is stopped, the doors are fully opened and all passengers are removed from the car. Alight the car and ensure the safety of the passengers.If the car is running, issue a stop command to the control device (8) and stop the car at the nearest floor.When the car stops and the door opens, the control operation is complete. The light lighting signal (4C) becomes IBJJ, and the control operation completion light (7) lights up, indicating that the evacuation is complete.

Even after the earthquake ends, the car is not allowed to run until a predetermined period of time has elapsed.

Next, when the fire detector (3) detects a fire, the fire detection signal (3a) becomes rHJ, and the fire control light lighting signal (4b) becomes "H" in the same manner as described above. Now, the fire control light (61) lights up, indicating that fire control operation has started.If the car is stopped and you start to panic, immediately close the door and head towards the mh floor (usually the 1st floor). Go.If,
If you go up above the evacuated floor and go to the power turn,
Immediately stop the vehicle with all doors closed and proceed towards the evacuation floor. If the car is running in a downward direction above the evacuation floor, it will not stop at any intermediate floor and will continue straight to the evacuation floor. When the car arrives at the evacuation floor and the door is opened, the control operation completion light lighting signal (4c) becomes rHJ, and the control operation completion light (7) turns on, indicating that the evacuation is complete. Cars will not be allowed to run until the fire is extinguished. In addition, the staff member should also check the fire control command switch (1
) After full operation, the fire control command signal (1a) becomes rHJ, and fire control operation is performed in the same manner as above.

In addition to the above-mentioned earthquake control operations and fire control operations, emergency control operations include power outage control operations. This is not shown in Figure 1, but when a power outage occurs, emergency power sources (in-house power sources, batteries, etc.) are used to return the number of cars corresponding to the power capacity to the evacuation floor one by one, and all units are returned to the emergency power source. Once completed, the number of cars that match the power supply capacity (91) will continue to operate to accommodate elevator users.

In such an emergency, passengers can quickly escape from the car,
In order to ensure the safety of passengers, VC must absolutely avoid situations where controlled operation cannot be performed due to a failure in the control operation circuit. However, the occurrence of the above-mentioned emergency state is extremely rare, and there are very few opportunities for the above-mentioned controlled operation to be performed, making it more difficult for failures in the controlled operation circuit to be discovered.

Therefore, in order to quickly discover failures in the control operation circuit,
It would be good to conduct controlled test runs frequently, but in reality, test runs cannot be performed frequently because it requires time and manpower for both the manager of the building where the elevator is installed and the elevator maintenance company. is the current situation.

This invention improves the above-mentioned problem by generating a simulated signal that simulates the entire emergency state, and inputting this signal to the car management device regardless of the detection of the entire emergency state to cause the car to be operated under full control. To provide an elevator inspection operation device which allows inspection operation to be carried out at any time without consuming time and effort.

Hereinafter, one embodiment of the present invention will be fully explained with reference to FIG.

In the figure, (9) is a failure diagnosis device installed at a maintenance company that outputs a command signal for inspection operation and an imitation signal 'iEj, and also inputs a signal indicating the elevator status to perform a failure diagnosis.

Other than the above, the configuration is the same as in FIG. 1.

Next vc% The operation of this embodiment will be explained.

When the inspection operation command is not issued from the failure diagnosis device R (9), each signal -Q (la) ~ (3a,) or OR gate (
By inputting the information to the car management device (4) through 121 to (14), the controlled operation is performed in 4) in FIG.

When performing inspection operation of earthquake control operation by remote control i7
When the inspection operation command is issued from the failure diagnosis device (9), C is the transmitter fjlt (+ol and receiver
The inspection operation command signal (X1a) is transmitted via rH
becomes j. In this process, the car management device (4) issues a command to the car control device (8) to operate the car I/C one floor at a time between the bottom floor and the top floor, so-called each floor stop. Have them drive. The status of the car while it is stopped and running on each floor is 8th floor (19) and the receiving device 201? Through the fault diagnosis device (
9) Send it to? c car position signal (151, up and down direction signals (16a), (16b), running signal 07
and the door switch signal qδ; Therefore, when the corner reaches a predetermined state, an earthquake simulation signal (11b) is sent to the sword at full timing. In winter, an earthquake simulation signal (
If ll'b) becomes rHj, OR Kate 04
) output becomes rHJ, and as explained in Figure 1, the earthquake control light (5) lights up, the car stops at the neck Vζ6th floor, the door opens, and the control operation completion light (7) lights up. Ding.The state of the river force 1 and the lighting state of the earthquake control light (bI support and control operation completion light (A)) are determined by the failure diagnosis device ( 9) Send to
whether the car operates according to predetermined procedures;
It is detected whether the earthquake control light lighting signal (4a) and the control operation completion light lighting signal (4C) are output without fail. If an abnormality is detected, the abnormality light (9A
) lights up to indicate a malfunction. Furthermore, if no abnormality is detected as a result of the inspection operation for various car conditions, the normal light (9B) is turned on and the inspection operation ends.

In addition, when a fire control operation is performed by remote control, when the inspection operation command signal (lld) becomes rHj, the management device (4) causes the car to stop at each floor.

Then, when the condition of the car reaches a predetermined condition, a fire simulation signal (llc) (also (-i fire control command signal signal (lld)) is issued. When driving uphill, the fire simulation signal (llc
) (or fire control command signal (F], a)) becomes rHJ, OR gate (1 or OR gate (
121) output becomes rHJ, the fire control light (6) lights up as explained in Figure 1, and the car immediately stops at the nearest floor, the 6th floor, with the door open, and then heads to the next V (destination floor). When the car reaches the evacuation floor and opens the door, the control operation completion light (7) lights up.These operations are detected by the fault diagnosis device (9), and if there is an abnormality, the abnormality light (9A) is turned on. lights up, and if it is normal, the normal light (9B) lights up.

In this example, we will use remote control to inspect control operations during earthquakes and fires, but the invention is not limited to this. Power outage control operation such as recall operation and continuous operation during power outage, earthquake control operation by detecting the initial tremor of an earthquake, and rescuing stunned passengers by running cars stopped in the express section at low speed during an earthquake. Rescue operations, inspection operations to determine whether it is okay to return to normal operation after the earthquake has subsided, and emergency operations to stop the car on the highest floor when the building is severely damaged during strong winds such as a typhoon. In addition to controlled operation, when inspecting automatic emergency operations in the event of an elevator failure, such as traveling to the next floor when the door cannot be opened, repeated closing of the door when the door cannot be opened, and opening the fault when it is detected that the elevator is unable to depart. It is clear that VC can also be used.

1. I made it possible to perform fault diagnosis automatically and display the diagnosis results, but it does not necessarily have to be automatic. It is sufficient to provide at least means for issuing necessary commands for diagnosis and means for displaying the status of the car so that the operator can determine whether or not there is a failure. 1. It is also possible to make it possible to diagnose the failure of one of several baskets of bales.

Furthermore, for example, the earthquake @Chitsukuda (2a) and the earthquake simulation (Th (lxb)) may be switched by a switching circuit (not shown) to be manually input to the management 4H1/mu). As for the device d that causes the earthquake sensor (21) to vibrate, the vibration device may be operated in response to a command from the failure diagnosis device (9) to fully operate the earthquake sensor (2).

In addition, when the "inspection operation" b condolence signal (lla) is issued, the car is made to stop running on the floor.
/Koshi, so that you can freely change the state of the basket (・(
This allows more detailed fault diagnosis to be performed.

The officer vC1 failure diagnosis age 1 bottle + 91 may be better if the power sold is better in the case of a large building.

In this case, the command signal for inspection operation and the 4I transmission Gl-6 reception signal indicating the state of the corner need not necessarily be transmitted through a telephone line.

As explained above, in this invention, a simulated signal simulating an emergency situation is generated, and this signal is input to the car management device regardless of the occurrence of an emergency situation to cause the car to be operated under control, which saves time and effort. Elevator inspection operations can be performed at any time without requiring maintenance.
