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, 1 is a fire control command switch installed on the staff management panel installed in the building manager's room, 1a is a fire control command signal that becomes "H" when fire control command switch 1 is turned on, and 2 is a fire control command signal. Earthquake detector 2a installed in the elevator machine room.
Earthquake detection signal becomes "H" when an earthquake of 80 gal or higher is detected, 3 is a fire detector installed in the machine room or elevator landing, 3a is a fire detector 3 that detects smoke or heat above a certain temperature. The fire detection signal 4, which becomes "H", controls the operation of the elevator car and also includes a control operation circuit (not shown) that performs management operation in the above-mentioned emergency, and determines the setting of the driving direction, running, and stopping. , a car management device that manages various functions such as door opening/closing commands, attendant management panel 1, car and display on the landing, 4a is an earthquake control light lighting signal, 4b is a fire control light lighting signal, 4c is a traffic control Operation completion light lighting signal, 5 to 7 are earthquake control lights, fire control lights, and control operation completion lights provided on the staff management panel, respectively; 8 is a car control that controls the operation of the car according to commands from the car management device 4; It is a device.

That is, when the earthquake sensor 2 detects an earthquake of 80 gal or more, the earthquake detection signal 2a becomes "H",
The control operation circuit in the management device 4 operates, and the earthquake control light lighting signal 4a becomes "H". with this,
The earthquake control light 5 lights up to indicate that earthquake control operation has begun. And if the car is stopped,
Open the door and let all passengers get out of the car to ensure their safety. If the car is running, a stop command is issued to the control device 8 to stop the car at the nearest floor. When the car stops and the door opens, the control operation completion light lighting signal 4c becomes "H" 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 passed.

Next, when the fire detector 3 detects a fire, the fire detection signal 3a becomes "H", and the fire control light lighting signal 4b becomes "H" in the same manner as described above. The fire control light 6 now lights up, indicating that fire control operation has begun. If the car is stopped, the car immediately closes the door and runs toward the evacuation floor (usually the first floor). If the car is running upwards above the evacuation floor, it should be immediately stopped with the door closed and the car should continue to run toward 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 is "H".
Then, the control operation completion light 7 lights up, indicating that the evacuation has been completed. Cars will no longer be allowed to run until the fire is contained. Further, when the staff operates the fire control command switch 1, the fire control command signal 1a becomes "H", and the 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 the first
Although not shown in the diagram, when a power outage occurs, an emergency power source (in-house power source, battery, etc.) returns the number of baskets to the evacuation floor in sequence according to the power capacity.
After all the elevators have returned, the number of cars commensurate with the power supply capacity will continue to operate to accommodate elevator users.

In order to quickly escape passengers from the car and ensure their safety in such an emergency, it is absolutely necessary to avoid a situation where controlled operation cannot be performed due to a failure in the controlled operation circuit. However, the occurrence of the above-mentioned emergency situation 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 is recommended to conduct test runs of the control operation frequently, but in reality, it is important for the manager of the building where the elevator is installed to also consult the elevator maintenance company. However, the current situation is that trial runs cannot be performed frequently because they require time and manpower.

This invention improves the above-mentioned problem by generating a simulated signal simulating an emergency state, inputting this signal to the car management device regardless of the detection of the emergency state, and causing the car to be operated under control. An object of the present invention is to provide an elevator inspection operation device that allows inspection operation to be performed at any time without requiring time and effort.

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

In the figure, reference numeral 9 is a failure diagnosis device installed at a maintenance company that outputs command signals and simulated signals for inspection operation, and also inputs signals representing the status of the elevator to perform failure diagnosis. 9A is a failure diagnosis device 9. The installed abnormality light, 9B, is also a normal light, 10 is a transmitter installed on the maintenance company side and transmits inspection command signals and simulated signals through the telephone line, 11 is installed on the building side and receives the signal from the transmitter 10. 11a is an inspection operation command signal that becomes "H" when remote commanding an inspection operation of control operation, 11b is an earthquake simulation signal that becomes "H" when simulating the occurrence of an earthquake, and 11c is a signal that simulates the occurrence of a fire. 11d is a fire control command simulation signal that becomes "H" when simulating the activation of fire control command switch 1, 12 to 14 represent the OR gate, and 15 represents the floor where the car is located. The car position signal 16a is an up direction signal which becomes "H" when the car is running in the up direction, 16b is a down direction signal which becomes "H" when the car is running in the down direction, and 17 is "when the car is running". 18 is a running signal that becomes ``L'' when the car door is stopped; 18 is a door switch signal that is ``H'' when the car door is closed; and ``L'' when it is open; 19 is a signal that is provided on the building side and is transmitted from the car management device 4. Input 4a of
A transmitter 20 inputs signals 4c, 15, 16a, 16b, 17, and 18 and sends them out through a telephone line, and 20 is provided at the maintenance company and receives signals from the transmitter 19 and sends them to the fault diagnosis device 9. It is a receiving device. Note that the failure diagnosis device 9 and the transmitting device 10 constitute a simulated signal generating device, and the receiving device 11 and the OR gates 12 to 14 constitute an input device. Other than the above, the configuration is the same as in FIG. 1.

Next, the operation of this embodiment will be explained.

When the inspection operation command is not issued from the failure diagnosis device 9, each signal 1a to 3a is output from the OR gate 12 to
By inputting the information to the car management device 4 via the terminal 14, a controlled operation is performed in the same manner as in FIG.

When performing an inspection operation of an earthquake control operation by remote control, an inspection operation command is issued from the fault diagnosis device 9 and transmitted via the transmitting device 10 and the receiving device 11, and the inspection operation command signal 11a is set to "H". becomes. The car management device 4 then issues a command to the car control device 8 to cause the car to operate one floor at a time between the bottom floor and the top floor, so-called floor-stop operation. The status of the car in stopped operation on each floor is transmitted to the failure diagnosis device 9 via the transmitting device 19 and receiving device 20, including the car position signal 15, up and down direction signals 16a and 16b, running signal 17, and door switch signal 18. You can find out by reading. Therefore, the earthquake simulation signal 11b is emitted when the car reaches a predetermined state. If the earthquake simulation signal 11b becomes "H" while the car is running in the upward direction between the 5th and 6th floors, the output of the OR gate 14 also becomes "L", as explained in Fig. 1. The earthquake control light 5 lights up, the car immediately stops on the 6th floor, the door opens, and the control operation completion light 7 lights up. During this time, the condition of the car and the lighting conditions of the earthquake control light 5 and control operation completion light 7 are transmitted to the fault diagnosis device 9 via the transmitting device 19 and the receiving device 20, and whether the car operates according to a predetermined procedure or not is sent to the fault diagnosis device 9 via the transmitting device 19 and the receiving device 20. It is detected whether the earthquake control light lighting signal 4a and the control operation completion light lighting signal 4c are outputted without fail. If an abnormality is detected, the abnormality light 9A lights up to indicate the failure. In addition, as a result of inspection operations for various car conditions,
If no abnormality is detected, the normal light 9B lights up and the inspection operation ends.

Further, when the fire control operation is performed by remote control, when the inspection operation command signal 11d becomes "H", the management device 4 causes the car to stop at each floor. Then, a fire simulation signal 11c (or a fire control command simulation signal 11d) is issued when the state of the car reaches a predetermined state. 5 baskets
If the fire simulation signal 11c (or fire control command signal 11d) becomes "H" while traveling in the upward direction between the 6th floor and the 6th floor, the OR gate 13 (or
The output of the OR gate 12) also becomes "H", the fire control light 6 lights up as explained in Fig. 1, and the car immediately stops on the nearest floor, the 6th floor, with the door closed.
Next, run toward the evacuation floor. When the car arrives at the evacuation floor and the door is opened, the control operation completion light 7 lights up. These operations are detected by the fault diagnosis device 9,
If there is an abnormality, the abnormal light 9A lights up, and if it is normal, the normal light 9B lights up.

In the embodiment, control operation inspections during earthquakes and fires are performed by remote control, but the present 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, earthquake rescue operation in which cars stopped in the express section are run at low speed to rescue passengers when an earthquake occurs, In addition to inspection operations to determine whether normal operation can be resumed after an earthquake has subsided, and strong wind control operations in which cars are stopped at the nearest floor when the building shakes strongly during strong winds such as typhoons, doors cannot be opened. This can also be applied to remote control inspections of automatic emergency operations in the event of an elevator failure, such as traveling to the next floor upon detection, closing/returning operation when the door cannot be closed, and disconnection of the faulty car when departure is detected. It's obvious.

Moreover, although failure diagnosis is automatically performed and the diagnosis results are displayed, it does not necessarily have to be automatic. At least means capable of issuing commands necessary for diagnosis and means for displaying the status of the car may be provided so that the operator can determine whether or not there is a failure. Furthermore, it is also possible to perform failure diagnosis for a plurality of cars using a single failure diagnosis device.

Furthermore, for example, the earthquake detection signal 2a and the earthquake simulation signal 11b may be input to the management device 4 by switching between them using a switching circuit (not shown). Also,
A device for vibrating the earthquake sensor 2 may be provided, and the vibration device may be operated to operate the earthquake sensor 2 in response to a command from the failure diagnosis device 9.

Further, when the inspection operation command signal 11a is issued, the car is stopped and operated on each floor, but the present invention is not limited to this. For example, the state of the car can be changed freely by issuing a call for any floor. It may also be possible to change the configuration to a more precise fault diagnosis.

Furthermore, in the case of a large building, it may be better to install the fault diagnosis device 9 in the safety center of the building. In this case, the means for transmitting and receiving command signals for inspection operation and signals representing the condition of the car does not necessarily have to be a telephone line.

As explained above, in this invention, a simulated signal simulating an emergency condition is generated, and this signal is inputted to the car management device regardless of the occurrence of the emergency condition to cause the car to operate under control, and to detect abnormalities in the operation of the car. Since the judgment is made automatically, the operation of the entire elevator control system can be checked without requiring time and effort, and inspection operation can be performed at any time to check whether control operation in an emergency can be performed normally. Can be done.
