Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to control of an abnormality notification device during automatic elevator inspection.

Since elevators move people up and down, it is stipulated that they be thoroughly inspected. Various inspection operations for inspecting the elevator include the following.

(a) Inspection by stopping each floor and opening/closing each floor.

(b) Inspection for returning to normal operation after an earthquake.

(c) Control operation in emergencies such as power outages, fires, earthquakes, etc.

(d) Checking the operation of indicators, etc.

Conventionally, these various inspections have generally been carried out by a staff member or maintenance person while riding the car and driving the car.

However, this kind of inspection while riding in the car requires a lot of manpower, and frequent inspections require even more manpower, so in recent years automatic inspections using remote control have become more and more popular. It tends to be done.

FIG. 1 is a circuit diagram showing an example of a device having an automatic inspection function by remote control. In the figure, a fire detector 1 generates a fire detection signal 1a of "H" level when it detects a fire. 2
is a failure diagnosis device installed at an elevator maintenance company, and has an abnormal light 2a and a normal light 2b that indicate the diagnosis results. 3 is a transmitting device that supplies various command signals generated from the failure diagnosis device 2 to a receiving device 4 provided at the location to be inspected via a telephone line; 6 is a transmitting device 5 that transmits various statuses of the elevator; This is a receiving device that receives information sent via a telephone line and supplies it to a fault diagnosis device. In this case, the receiving device 4 outputs an inspection operation command signal 4b and a fire simulation signal 4a that are issued from the maintenance company's failure diagnosis device 2 and sent via the transmitting device 3. 7 is an OR gate which receives as input the fire detection signal 1a generated from the fire detector 1 and the fire simulation signal 4a generated from the receiver 4; 8 is the output of the inspection operation command signal 4b generated from the receiver 4 and the OR gate 7; This is an elevator control device that receives as input, and has a fire control circuit that controls the operation of the car and performs controlled operation in the event of a fire. 8a to 8g are various output signals generated from the elevator control device 8, of which 8a is a car position signal indicating the elevator car position, and 8g is an up direction signal indicating the up direction movement of the car as an "H" level signal. , 8d is a down direction signal, 8b is a running signal that indicates "H" when the car is moving, 8c is a door switch signal that is "H" when the car door is closed and "L" when it is open, and 8e is a door switch signal that is "H" when the car door is closed. 8f is a fire control signal which becomes "H" during the fire control operation, and a fire control completion signal which becomes "H" at the end of the fire control operation.

Next, 9 is activated when it detects the occurrence of a fire control signal 8e generated from the elevator control device 8, and informs passengers of the occurrence of a fire through a speaker 10 provided in the car and urges them to evacuate. 11 and 12 are fire control lights installed in the car and on the staff management panel; 13 is an abnormality bell installed on the staff management board; these fire control lights 11 and 12 and abnormal The bell 13 is activated by the fire control signal 8e. 14 is a fire control completion signal 8f generated from the elevator control device 8
This is the control operation completion light that is activated by the These constitute a notification device 15 that displays guidance inside the car and on the attendant management panel.

In the device configured as described above, when the fire detector 1 detects heat from smoke, the fire detection signal 1a generated becomes "H" and is supplied to the elevator control device 8 via the OR gate 7. The elevator control device 8 generates a fire control signal 8e immediately after the fire control circuit provided therein is activated. When the fire control signal 8e is generated, the broadcasting device 9 is first activated and a message saying "A fire has broken out. We are now heading to the evacuation floor" is made inside the car via the speaker 10. At the same time, the fire control light 12 inside the car lights up, and the abnormality bell 13 provided on the staff management panel rings to notify the user of the occurrence of a fire.

On the other hand, the elevator control device 8
At the time when the fire signal 7a supplied from the car becomes "H" and is generated, if the car is stopped, the car immediately closes the door and departs for the evacuation floor (usually the first floor). In this case, when the car is traveling in the upward direction on a floor above the evacuation floor, it is immediately stopped at the nearest floor with the door closed, and then made to proceed directly to the evacuation floor. Furthermore, when the car is traveling in a downward direction on a floor above the evacuation floor, the car ignores calls at intermediate floors and is allowed to go straight to the evacuation floor. Then, when the car goes straight to the evacuation floor and the door is opened, the fire control completion signal 8f becomes "H", so the control operation completion light 14 lights up to notify that the evacuation is complete.

The above is the operation of the control operation when a fire actually occurs.Next, the case where the fire control operation is inspected by remote control will be explained.
First, the failure diagnosis device 2 installed at the maintenance company
When an inspection operation instruction is issued by the operator, this signal is sent from the transmitter 3 to the receiver 4 via the telephone circuit. Therefore, upon receiving this command signal, the receiving device 4 supplies the inspection operation command signal 4b to the elevator control device 8 as an "H" level signal.

On the other hand, the elevator control device 8 is activated by being supplied with the inspection operation command signal 4b, and is caused to perform a so-called floor-by-floor stop operation in which the floors between the top floor and the bottom floor are operated one by one. The status of the elevators in stopped operation on each floor is supplied from the elevator control device 8 to the notification device 5, where it is sent via the telephone line to the receiving device 6 provided at the maintenance company. When the receiving device 6 receives the signals sent via the telephone line, it supplies all the signals to the fault diagnosis device 2. In this case, the signal sent to the failure diagnosis device 2 is the car position signal 8.
a, car running direction signal 8g, 8d, running signal 8
b and a door switch signal 8c, and fault diagnosis is performed from these signals.

Next, when the elevator is in a predetermined state, the failure diagnosis device 2 issues an instruction to simulate a fire outbreak. For example, when the fire simulation signal 4a is emitted from the receiving device 4 while the car is traveling upward between the 5th and 6th floors, the fire signal 7a emitted from the or gate 7 also becomes "H" and is transmitted to the elevator control device. The fire control circuit in 8 is activated and a fire control signal 8e is generated. When the fire control signal 8e is issued, as in the case described above, fire control operation guidance is provided inside the car and on the attendant management panel, and the car immediately stops on the nearest floor, the 6th floor, with the door closed. Then, head straight to the first floor, which is the evacuation floor. When the car reaches the first floor and the door is opened, the fire control completion signal 8f becomes "H" and the fire control completion light 14 lights up.

On the other hand, the fault diagnosis device 2 instructs the operation of the elevator car and the guidance display according to a predetermined procedure based on signals indicating the elevator status and the guidance display status sent from the elevator control device 8 during this time. A check is made to see if this has been done correctly, and if an abnormality is detected, the abnormal light 2a is turned on, and if no abnormality is detected, the normal lamp 2b is turned on.

Inspection of controlled operation by remote control is
Since it does not require much manpower or effort, it can be done more frequently, and failures can be detected earlier and countermeasures can be taken. Therefore, even in the event of a fire, passengers can be evacuated reliably and completely.

However, in the above-mentioned configuration, the same guidance display as in actual control operation is performed during inspection operation, so if a passenger happens to be in the car when the inspection operation instruction is sent out, the passenger may actually be in danger of a fire. This will cause unnecessary confusion in the car. In addition, an extremely urgent and abnormal display such as the ringing of a bell will be displayed on the staff management panel, which will cause unnecessary confusion for the staff even if the inspection operation is in progress. The inconvenience of such inspection operations performed by remote control without staff entering the car is not limited to fire control operations, but also control operations during emergencies such as power outages and earthquakes, and operation to the next floor when it is detected that the door cannot be opened. This will also occur when inspecting automatic emergency operations in the event of an elevator failure, such as repeated door closing operations when the door cannot be closed, and operation to disconnect the failed car when it is unable to depart.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an elevator notification device that does not cause unnecessary confusion to passengers or staff when inspecting an elevator by remote control, in order to eliminate the above-mentioned drawbacks. . Hereinafter, an elevator notification device according to the present invention will be explained in detail using the drawings.

FIG. 2 is a circuit diagram showing an embodiment of the elevator notification device according to the present invention, and the same parts as in FIG. 1 are indicated using the same symbols. In the same figure, 1
6 is a fire simulation signal 4a emitted from the receiving device 4;
17 is an AND gate that inputs the fire control signal 8e generated from the elevator control device 8 and the output of the inverter 16. and is configured to be supplied to the abnormality bell 13.

In the elevator notification system configured as described above, when the fire simulation signal 4a is sent during inspection operation by fire control operation, the inverter 16
The output of is inverted to "L". When the output of the inverter 16 becomes "L", the output of the AND gate 17 is forced to "L", so the fire control signal 8
Even if e occurs, the broadcasting device 9, fire control light 11, and abnormality bell 13 do not operate. Therefore,
Unnecessary confusion for passengers and attendants in the car is prevented. When the car returns to the evacuation floor, the fire control completion signal 8f becomes "H".
In conjunction with this, the completion light 14 on the staff management panel lights up.

On the other hand, since the fire control signal 8e and the fire control completion signal 8f are supplied to the transmitting device 5 as in the case of FIG. 1, these signals are supplied to the fault diagnosis device 2 via the telephone line and receiving device 6. The timing of displaying information is checked.
It is determined whether there is a failure in the fire control operation circuit system. In addition, when the inspection operation is not in progress,
The fire simulation signal 4a becomes “L” and the inverter 1
Since the output of the gate 6 is "H", when a fire actually occurs and the fire control signal 8e becomes "H", the output of the AND gate 17 becomes "H", and the A predetermined guidance display will also be displayed on the staff management board.

In the above embodiment, only operation control in the event of a fire has been described, but it can also be applied to control operation in the following modes.

(A) During remote inspection operation of emergency control operations other than fire (control operation during power outages, earthquakes, typhoons, etc.), some or all of the emergency guidance will be disabled.

(B) Disable some or all of the abnormality indications for automatic emergency measures (operation to move to the next floor when the door cannot be opened, repeated door closing operation when the door cannot be closed, operation to disconnect the failed car when departure is impossible, etc.) .

(C) In addition to emergency and abnormality displays inside the car and on the attendant management panel, disable control of emergency and abnormality displays at the landing.

(D) Disable only the auditory display among the emergency and abnormal display.

(E) Rather than disabling part or all of the emergency display or abnormal display, perform control to change the display format.

As explained above, the elevator notification device according to the present invention is designed to prevent part or all of the guidance display from operating when inspecting the elevator by remote control, so it is difficult for elevator users and staff to This has the excellent effect of preventing unnecessary confusion.
