Description

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

Inspection operations to check whether an elevator is malfunctioning include the following.

a. Inspection by stopping each floor and opening/closing each floor; Color inspection when returning to normal operation after an earthquake; C1 Inspection of operation in emergencies such as power outages, fires, earthquakes, etc. d0 Inspection of operation of indicators. These inspections This is normally carried out by a staff member or maintenance worker who gets into the elevator car and operates it.

Recently, in order to save the labor of the attendants, the cars are operated by remote control without the need for people to board the cars.At the same time, since the attendants are not in the corner, inspection operations are started with passengers still on board. In addition, there is a possibility that passengers may board the vehicle during inspection, which may cause safety problems.

This invention is intended to improve the above-mentioned problems, and the elevator automatic operation can be performed when it is detected that there are passengers in the car during inspection operation. A transmitting device (++) is provided on the building side and transmits the inspection operation command by wire or wirelessly, and a receiving device (02) that receives the above command and issues an inspection operation command signal (llal) causes the car to respond to a call. The elevator control device (12a) not only performs basic control of the elevator such as running and stopping control and door opening/closing control, but also controls inspection operation by the inspection operation command (M number (lla)). From the time of receiving the test until the actual inspection operation
The inspection operation preparation signal (12b) becomes HJ, and the inspection operation forced setting signal (12b) becomes r'HJ when forcibly transitioning to inspection operation or temporarily interrupting inspection operation.

Riha memory! A memory similar to 3η, (90a) is the output of the memory (90), and is a stop command 4t= which stops 'D\' when it becomes "H".

In Fig. 5, (92) is the 1st floor call response signal which becomes rHJ when the landing button on that floor is pressed when the door is stopped with the door closed, and becomes rLJ again when the door is opened.
3) is a door opening time setting that becomes "L" when the 1st floor call response signal (92) becomes rHJ, or when it starts running, becomes rHJ, and after a predetermined time (for example, 4 seconds) has elapsed after the door has stopped and the door has been opened. signal, (94) is an AND gate, (95) is an OR gate, (96) is a NOT gate, (97) is an OR gate,
(97a) is the output of the OR game (97), which is a door opening/closing command signal that commands the door to be opened when rLJ and to close the door when rHJ.

Next, the operation of this embodiment will be explained.

Assuming that no inspection operation command is issued now, inspection operation command signal (lla), inspection operation slander -@ (12c), inspection operation preparation signal (121L), inspection operation forced setting signal (
U2b) are all rLJ.

Assuming that the car is on the 1st floor and set in the up direction, and that the up call for the 2nd floor and the car call for the 5th floor are registered, the up direction signal (83), up call signal (2b), and up call signal (5a) are all "H".

At this time, since the output of the NOT gate (42) is rHJ, the output of the AND gate (44) is rHJ, and the output of the OR gate (55) is also rHJ. When the car leaves the first floor and approaches the second floor, the force/position signal (2d) becomes rHJ, so the output of the AND gate (65) becomes rHJ, and the output of the OR gate (80) also becomes rH.
It becomes J. Then, the output of the AND gate (Fi5) becomes rHJ, and the output of the OR gate (87) also becomes rH.
It becomes J. At this time, the running signal (88) becomes rHJ, so the output of AND game (89) is rHJ.
Therefore, the memory (90) is set and the stop command signal (90a) becomes rl (J.) Now, the vehicle (c) starts decelerating and stops at the 7.2nd floor. That is, it responds to the call from the second floor. (At this time, the second floor up call signal (2b)
becomes rLJ. ) When the car comes to a complete stop, the running signal (8B) becomes rLJ. On the other hand, the door opening time setting signal (9
3) is “)1”, so OR gate (95)
The output of is rHJ, and the output of NO'x' dart (96) is rLJ, so the output of OR gate (97), that is, the door opening/closing signal (97a) becomes rLJ, and the car door starts to open. When 4 seconds have passed after the door opening is completed, the door opening time setting signal (93) becomes rLJ, so OR game) (95
) becomes rLJ, and the output of NOT gate (96) becomes rHJ. Now, the door opening/closing command signal (97a), which is the output of the OR gate (97), becomes rHJ, and the door begins to close.

At this time, the door closing signal - becomes "■", so the memory (90) is reset and the stop command signal (90a) becomes rLJ. When the door is completely closed, the car departs toward the 5th floor, approaches the 5th floor, and receives the car position signal (5(1) r).
When it comes to HJ, AND gate (78), OR game) (
82), the output of the OR gate (87), and the AND gate (89) becomes rHJ, and the memory (90) is set.
The stop command signal (90a) becomes rHJ, the car stops at the 5th floor, and the door begins to open. The above is a normal operation.Next, when the car is on the 1st floor and set to the up direction, and the up call for the 2nd floor, and the calls for cars on the 3rd and 5th floors are registered, the transmitter not Assume that an inspection operation command is issued. The receiving device fIt (11) receives this, and the inspection operation command signal (lla) becomes rHJ. However, Kadokanabi th” Am (3!L) (not shown) and Kadocall (
Since No. N (5 &) is rllllJ, the passenger detection signal (26!L) is rEJ, NOT game) (3
Since the output of ++ is rLJ, the output of the AND gate iron is rLJ. Therefore, the memory @η is not set and the inspection operation signal (12c) remains rLJ.

In addition, the output of the AND gate (29) is also rLJ, and the output of timer 1 (40a) does not become rHJ until 600 seconds have passed after the inspection operation command signal (lla) becomes rHJ. is also rLJ,
The output of the OR gate is rLJ. therefore,
Memory (to) is not set, forced setting signal (1zb)
also remains rLJ. However, since the outputs of the NOT gate μs and the rabbit are both rHJ, as soon as the inspection operation command signal (lla) becomes "H", the inspection operation preparation signal (12a) becomes "H". Now, the broadcasting device 00 is activated, and the speaker (1~) broadcasts the message "Inspection operation will soon begin" to the inside of the car, and periodically (for example, every 20 seconds) announces that the inspection operation has entered the preparatory stage. On the other hand, the output of the NOT gate (42) is r
LJ, the outputs of the AND gates (43) to (52) are all closed, and the second floor up call signal (2b) becomes invalid. In the past, when the car departed from the first floor, it would be driven to answer calls from the third and fifth floors.

When the car responds to the call on the 3rd floor, then stops and opens the door on the 5th floor call, the car call signal (5a) is rLJ.
becomes. Once the doors have been opened and all passengers have exited the vehicle,
The scale signal 08) becomes rLJ, and the passenger detection signal (26
a) becomes rLJ, and the output (39a) of timer (a)
) becomes rLJ. Then, when 4 seconds have passed after the door opening is completed, the door opening time setting signal (93) becomes rLJ, the output of the OR gate (95) becomes rLJ, the output of the NOT gate (96) becomes rHJ, and the output of the OR gate (97) becomes rLJ. The output, that is, the door opening/closing command signal (97a) becomes "H" and the door begins to close. Now, the door closing signal (goods) is "H"
Therefore, the output of the OR gate (5) becomes rHJ.

At this time, the stop signal (191 is rHJ, NOT
Since the output of the gate @1) is also rHJ, the output of the AND gate (27) is rHJ, η in the memory is set, and the inspection operation signal (12c) becomes rHJ. Therefore, the output of the NOT gate becomes "L", the inspection operation preparation signal (12a) becomes rLJ, and the guidance broadcast to the inside of the car is to notify that the preparation stage has transitioned to full-scale inspection operation. The information changes to the guidance (for example, ``The vehicle is being inspected. It is dangerous, so please refrain from boarding the vehicle.'').

Also, since the inspection operation signal (12c) has become rHJ, the indicator light 071 inside the car and the indicator lights (17A) to (x7:c) in the landings on the first to sixth floors are lit.

If the door is already empty and waiting when the inspection operation command signal (lla) becomes rHJ, the door closing completion signal e21 is rHJ, and the output of OR game)H becomes "H". Therefore, the inspection operation signal (Ma2c) immediately changes to rH.
It becomes J. (At this time, the inspection operation preparation signal (12a) also becomes - instantaneous rHJ or becomes "L" before the broadcasting device IIO candy operates.) When the inspection operation preparation signal (12c) becomes rHJ, the OR gate is activated. The output of (53) becomes “kl”, and the output of OR gate (5
The outputs of 4) to (63) all become rHJ. This is the same as if all the up calls from the 1st to 5th floors and the down calls from the 2nd to 6th floors were registered. Therefore, even if a car call is not registered, the driving direction of the car is set, and the car is operated while stopping at each floor and opening and closing the doors. In this way, we can repeatedly stop each floor (during this period, the broadcast guidance during inspection operation is also repeated periodically, for example, every time we stop at each floor), and check that there are no abnormalities in operations such as opening and closing doors. automatically check. If an abnormality (for example, the door cannot be opened or closed) is detected, a failure detection signal (12 (1) is "■"
If no abnormality is detected, it becomes rLJ. Then, it is transmitted by the transmitting device I, received by the receiving device ON, and the result of the inspection operation is transmitted to the maintenance company.

Next, consider a case where even after 60 seconds have passed since the inspection operation command signal (lla) became "H", there are still car calls and it is not possible to shift to inspection operation. At this time, the output of the timer (40a) is rHJ, and the inspection operation signal (12 (!) is "L", so the output of the NOT gate is rHJ, and the output of the AND gate □□□) is rHJ. Become. Now, the output of OR game (24) becomes rHJ, the memory is set, and the forced setting signal (
12b) becomes r'EJ. And NOT gate (3
6) is rLJ, so the inspection operation preparation signal (1
2a) becomes "L" and the output of OR game (53) becomes rHJ, which is the same as if hall calls for all floors were registered. Therefore, if the car is running, it will stop at the nearest floor υ. Forced setting signal (
121)) becomes rHJ, the broadcasting device switches from the broadcast content before the inspection operation to the broadcast content urging everyone to get off the train, for example, ``Please get off the train at this floor.'' This broadcast is repeated periodically. The output of the AND gate (94) is rHJ until everyone has left the train (until the passenger detection signal (gaa) or rLJ is reached), so the output of the OR gate (95) is also rHJ, and NO
The output of the T gate (96) becomes "L". Also, since the running signal (88) is also rLJ, OR game) (97
), that is, the door opening/closing command signal (97a) is rLJ
'1 and the door will not close. When everyone gets off the train,
The passenger detection signal (26a) becomes rLJ, the door opening/closing command signal (97a) becomes rHJ, the door starts to close, and the door closing operation signal (e) becomes rHJ. Therefore, the output of the oR gate becomes rHJ, the memory (to) is reset, and the forced setting signal (12t+) becomes rLJ. On the other hand, as described above, at the same time as the door begins to close, the inspection operation signal (120) becomes rHJ, and inspection operation can be performed from now on.

Additionally, if a passenger accidentally gets into the car during inspection operation, the scale signal end will become rHJ, and if this passenger registers a call, any of the car call signals (la) to (6a) will become rHJ. Therefore, the passenger detection signal (26a) becomes rHJ. Now, the output of A) JD gate outside) becomes rHJ, the output of OR gate outside) becomes rHJ, the memory is set, and the forced setting signal (12b) becomes "■".

Also, the output of timer 09) becomes "H" after 1 second,
The output of the OR gate becomes "H", the memory period is reset, and the inspection operation signal (12 (!) becomes rLJ. In this case, as in the above case, after letting the passengers get off at the nearest floor, , inspection operation will be continued again.

The inspection operation is performed in this way, but in order to end the inspection operation, the maintenance company issues a command, and when the inspection operation command signal (lla) becomes rL, the NOT gate (
The output of 9) is rHJ, and the output of OR gate is rH
J, the memory 7) is reset, and the inspection driving signal (12c) becomes rLJ. Also, Miss NOT Gate)
The output of the OR gate becomes rHJ, so when the forced setting signal (12b) is rHJ and the inspection operation command signal (lla) becomes rLJ, the memory m, beam is set, and the forced setting signal (12b) becomes rHJ. The setting signal (12b) is r
Becomes LJ.

In the embodiment, the inspection operation includes stopping each floor and opening/closing each floor, but the inspection operation is not limited to this. It goes without saying that the present invention can also be applied to cases where a plurality of cars are arranged side by side. When multiple cars are installed side by side and inspection operations are carried out one by one or two or more cars at a time, check the results in order of inconvenience to passengers (for example, if there are fewer passengers in the car). You can be even more kind to passengers by choosing from among the baskets that are likely to be empty soon.

Further, although it is determined that there is a passenger in the car when the color of the scale device is activated or the car call is registered, the passenger detection device is not limited to this. A passenger detection device using an industrial television camera, ultrasound transmission, etc. may also be used.

Furthermore, when a passenger is detected in the car, the inspection operation is interrupted, and the inspection operation can be resumed after the passenger is allowed to exit the car at the next floor. However, the inspection operation can only be performed on the nearest floor. You may also be allowed to get off the train at a specific floor (main floor, bottom floor, top floor, M-difficult floor #). In addition, passengers in the car may be allowed to get off the car at their destination floor (the floor where the car call is registered) as in normal times. When the inspection operation is performed, if it is detected that there is a passenger in the car during the inspection operation, the inspection operation is interrupted, so that the inspection operation can be performed safely.
