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. b1. Normal operation after an earthquake [6. Inspection when returning to the home. Normally, this is carried out by a maintenance worker who gets into the elevator car and operates it.

Recently, in order to reduce the labor of the attendant, it has been proposed to operate the car by remote control and check whether predetermined operations are being performed without having a person climb into the car.

However, when carrying out inspection operations using remote control as described above, there are no attendants present in the car, so inspection operations may begin with passengers still on board, and there is also a possibility that passengers may board the car during inspection operations. There is a possibility that the above problem will occur.

This invention improves the above-mentioned problem, and when a check operation command is issued, the automatic check operation of the elevator is performed so that the check operation can be carried out safely by allowing passengers to get off the train and then proceeding to the check operation. The purpose is to provide equipment.

An embodiment of the present invention will be described below with reference to Figures 1 to 185.

In Fig. 1, (10) is a transmission device installed on the side of the maintenance company and transmits the inspection operation command signal line or wirelessly, and (++) is installed on the building side and receives the above command and sends the inspection operation command signal (
The receiving device, θ2, performs basic elevator control such as running and stopping control to make the car respond to a call, door opening/closing control, etc., as well as the inspection operation command signal (lla).

In Fig. 5, (92)/fi When the car is stopped with the door closed, the first floor call response signal becomes rHJ when the landing button on that floor is pressed, and becomes rLJ again when the door is opened;
(93) is a door opening time setting that becomes "L" when the first floor call response signal (92) becomes rHJ or when the vehicle starts running, becomes rHJ, and when a predetermined time (for example, 4 seconds) has elapsed after the door has stopped and the door has been opened. Signal, (94) is AND gate, (95) is OR
gate, (96) is the NOT gate, (97) is the OR gate, (97a) is the output of the OR gate (9)) which commands the door to open when it is "L" and to close it when it is rHJ. This is an opening/closing command signal.

Next, the operation of this embodiment will be explained.

Assuming that no inspection operation command is issued now, the inspection operation command signal (lla), inspection operation in progress signal (12c), inspection operation preparation signal (12a), and forced setting signal (12b) are all rLJ. There is.

If you are on the first floor of Kadokawa and the up direction is set, and the up call on the second floor and the car call on the sixth floor are registered, the up direction signal (83), the up call signal (2b) and the Kato call signal ( 5a) are all rHJ.

In this case, the output of the NO'l gate (42) is rHJ, so 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 car position signal (
2d) becomes rHJ, so the output of AND game) (65) becomes rHJ, and the output of OR game) (80) also becomes r
Becomes HJ. Therefore, the output of AND game (815) is rHJ, and the output of OR game (87) is also r
Becomes HJ. In this case, the running signal (88) is rHJ, but the output of AND game (89) is rHJ.
Therefore, the memory (90) is set and the stop command signal (90a) becomes rHJ. The car now starts decelerating and stops on the second floor. That is, it responds to the call from the second floor. (At this time, the second floor up call signal (2b) Fi
It becomes rLJ. ) When the car comes to a complete stop, the running signal (
8th) will be "L". On the other hand, the door opening time setting signal (93
) is "■", so the output of oR game) (95) is rHJ, and the output of NOT gate (96) is rI,
J, the output of the OR gate (9), that is, the door opening/closing signal (9'ya) 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 the output of the OR gate (95) becomes "L", and the output of the NOT gate (96) becomes "H".
”.

Now, the door opening/closing command signal (97a) which is the output of the OR game) (,9'/) becomes "HJ" and the door starts to close.At this time, the door closing operation signal -F;LrHJ becomes, so please take a note. (90) is reset and the stop command signal (90) is reset.
oa) becomes rLJ. Once the door is closed, the car departs towards the 5th floor, approaches the 5th floor, and transmits the car position signal (6d).
) becomes rHJIlc, AND gate ()8), OR
Gate (82), OR gate (8), AND game)
The output of (89) becomes rHJ, the memory (90) is set, and the stop command signal (90a) becomes rHJ, and the car stops at the 5th floor and starts sleeping with the door open. The above is normal operation.

Next, when Car 1 is on the 1st floor and the up direction is set, and the 2nd floor up call and the 3rd and 5th floor car calls are registered, an inspection operation command is issued from the transmitting device (10). Suppose that The receiving device (Il) receives this, and the inspection operation command signal (lla) becomes rHJ. However, the car call signal (3L) (not shown) and the car call signal (5a
) is rHJ, the passenger detection signal (26a) which is the output of the OR gate (26a) tel: rHJ,
The output of NOT gate (31) is rLJ, so A1
The output of the 11D gate is rLJ. Therefore, the memory @η is not set and the inspection operation signal (12o
) is up to the t of "L". Also, AND gate (c)
The output of timer 4 (401L) is also 6 after the inspection operation command signal (lla) becomes rHJ.
Since rHJ does not occur until 0 seconds have elapsed, the output of AND gate 4 is also "L", and the output of OR gate is "L".

Therefore, the memory is not set and the forced setting signal (
12b) also remains rLJ. However, NOT game)
], H are both rHJ, so as soon as the inspection operation command signal (lla) becomes rHJK, the inspection operation preparation signal (12a) becomes rHJ. Now, the broadcasting device Q@ is activated, and the speaker α broadcasts to the car that "inspection operation will soon begin", and the notification that the inspection operation has entered the preparation stage is periodically (for example, every 20 seconds). It is done repeatedly. On the other hand, 110T game) (42)
The output of is rLJ (9th, AND game) (43)~
All outputs of (52) are closed and the second floor up call signal (2b) is disabled. Therefore, when a car departs from the first floor, it is driven to answer calls from the third and fifth floors.

When the car responds to the third floor call, then stops and opens the door to the third floor call, the car call signal (51!L) is r.
LJ and Hiko. After the doors have been opened and all passengers have exited the vehicle, the scale signal α is set to rLJ and the passenger detection signal (2
6a) becomes rLJ, and the gravity of the timer country (39a) is r
Becomes LJ. Then, when 4 seconds have passed after the door opening is completed, the door opening time setting signal (93) becomes "L", and the OR gate (
The output of 95) is ti rLJ, the output of NOT gate (96) is rHJ, and the output of OFI gate (917) is
That is, the door opening/closing command signal (97a) becomes "H" and the door begins to close. Now, since the door closing operation signal - becomes rHJ, the output of the OR gate becomes rHJ. This color and the stop signal - are rHJ, and the output of the NOT gate @0 is also rHJ, so the output of the AND gate iron is rH
J, the memory 0η is set, and the inspection operation signal (
12c) becomes rHJ. Therefore, the output of the NOT gate is rLJ, and the inspection operation preparation signal (12a
) #'1rLJ, and the announcement to the inside of the car will be to notify that the preparatory stage has transitioned to full-scale inspection operation (e.g., ``Inspection operation is in progress. Please refrain from boarding the vehicle as it is dangerous.'') Can be switched. In addition, since the inspection operation signal (12C) became rHJ, the indicator light inside the car (lη) and the indicator light (1'7A) in the landings on the 1st to 6th floors
~(17K) lights up.

If the car is already empty and waiting when the inspection operation command signal (lla) becomes rHJ IC, the door closing completion signal @l) is rHJ, and the output of the OR gate is "H
”, the inspection operation signal (12c) is immediately activated.
is rHJ Totoru. (At this time, the inspection operation preparation signal (12
a) also becomes - instantaneous rHJ K, but the broadcasting device fl11 (becomes rLJ before the I wire operates). When the inspection operation signal (12a) becomes rHJ, the OR game
) The output of (53) becomes “E” and the output of OR gate (54
) to (63) are all rHJ. this is,
It is 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 door. In this way,
Each floor will be stopped (during this period, announcements will also be made periodically during inspection operations).
For example, while repeating 0) every time the vehicle stops at each floor, it automatically checks to see if there are any abnormalities in operations such as opening and closing doors. If an abnormality (for example, door cannot be opened, door cannot be closed, etc.) is detected, the failure detection signal (12d) becomes "H", and if no abnormality is detected, it becomes "L". Then, it is transmitted by the transmitting device H, received by the receiving device (141), 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 rHJ, there are still car calls and there is no way to shift to inspection operation. In this color, the output of timer 4 (40a) FirHJ and the inspection operation signal (12o) are rLJ, so the output of the NOT gate is rHJ, and the output of the AND gate is rH.
It becomes J. Now, the output of the OR gate becomes rHJ, the memory Q~ is set, and the forced setting signal (12b
) is expressed as rHJ. Since the output of the NOT gate (support) is rLJ, the inspection operation preparation signal (12a) is r
Along with becoming LJ, the W power of (OR game) (53) is “H
”, which is the same as if the landing calls for all floors were registered. Therefore, if the car is running,
The car stops at the nearest floor. When the forced setting signal (12b) becomes rHJ, the broadcasting device IQ5) changes from the broadcast content before the inspection operation, for example, "Everyone please get off at this floor."
The broadcast changes to a message urging people to get off the train. This broadcast is repeated periodically until all 0's get off the train (until the output of 0'R gate heat (26a) becomes rLJ) and the output of (94) becomes rHJ. Therefore, the output of (95) is also rl(J
(NOT game) The output of (96) becomes "L". Further, since the running signal (8th) is also rLJ, the output of the OR gate (9), that is, the door opening/closing command signal (99) becomes one rLJ, and the door does 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 begins to close, and the door closing signal becomes rHJ. Therefore, the output of the OR gate becomes rHJ, the memory is reset, and the forced setting signal (xzb) becomes rLJ. on the other hand,
As mentioned above, at the same time as the door begins to close, the inspection operation signal (Y2c) becomes rHJ, and the inspection operation can be performed from now on.

Additionally, if a passenger accidentally gets into the car during inspection operation, the scale signal Q@ becomes rHJ, and if this passenger registers a car call, any of the car call signals (1a) to (61) becomes rHJ. Therefore, the passenger detection signal (26a) is rHJ
becomes. Now, the output of the AND gate (c) becomes rHJ, the output of the OR gate (f24) becomes rHJ, the memory (c) is set, and the forced setting signal (12b) becomes "H".
” he says. Also, after 1 second of output ti of timer (2)),
H", the output of the OR gate appears as rHJ, the memory @7Fi is reset, and the inspection operation signal (lc
) becomes rLJ. In this case as well, the passenger will be allowed to get off the train at the nearest floor and then the re-Q inspection operation will be continued, as described above.

The inspection operation is performed in this way, but when one maintenance company issues a command to end the inspection operation and the inspection operation command signal (lla) becomes "L", the output of the NOT gate is rHJ. Then, the output of OR gate z is rHJ
As a result, the memory 1a7i is reset, and the inspection operation signal (Y2c) becomes rLJ. In addition, the output of the NOT gate is 11rHJ, and the output of the OR gate (c) is rHJ, so the forced setting signal (12'b) is rHJ.
When the inspection operation command signal (lla) goes to rLJK7, the memory is reset and the forced setting signal (
12b) becomes rLJ.

In the above embodiment, when receiving the inspection operation command, at least the car responds and shifts to the pressure inspection operation after all the passengers in the car have alighted, so the operation can be carried out safely without causing any inconvenience to the passengers in the car. Sleep by performing inspection driving. In addition, when receiving an inspection operation command, it responds to a car call and a landing call (or only a 51f & already completed landing call), and waits until there are no passengers in the car or passengers waiting at the landing before proceeding to inspection operation. It is also possible to avoid causing inconvenience to passengers in the car and passengers waiting at the landing.

In addition, if the inspection operation cannot be started even after a predetermined period of time has elapsed since the inspection operation order was issued, the system will force the vehicle to stop at the nearest 9th floor, allow passengers to get off the vehicle, and then proceed to inspection operation one after another. This eliminates the problem of not being able to proceed to inspection operation even after passengers have boarded the vehicle. Further, depending on the content of the inspection operation, there are cases where it is necessary to know the result of the inspection operation immediately. In this case, the timer decoy setting time T2
- by setting it short (for example, 1 second) or removing the timer from the circuit and directly transmitting the inspection operation command signal (111IL) to AN.
D goo) Enter it in f29) and click Cart? It is also possible to forcibly stop the vehicle at the nearest floor and shift to inspection operation.

In the embodiment, the inspection operation includes stopping each floor and opening/closing the pipes for each floor, but the inspection operation is not limited to this. It goes without saying that the present invention can also be applied to a case where a plurality of cars are arranged in parallel. 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, it is best to use cars that are less likely to cause inconvenience to passengers (for example, cars with few passengers). You can be very kind to passengers by selecting them in order, or by selecting them as soon as the sky seems clear.

In the embodiment, when the weighing device operates or when a car call is registered, it is determined that there is a car pressure passenger, but the passenger detection device is not limited to this, and may be an industrial television camera, A passenger detection device using ultrasound or the like may be used.

In addition, during inspection operations, etc. that are performed assuming a fire, a "fire operation" display will be displayed inside the car, so depending on the broadcast, 1. It is desirable to unnecessarily confuse and endanger passengers.

As explained above, in this invention, when an attendant automatically performs an inspection operation without getting into the car, the driver performs the operation necessary to disembark the passengers in the car, and detects that the passenger in the car has alighted. After that, the inspection operation is started, so that the inspection operation can be carried out safely without causing any inconvenience to the passengers in the car.

Furthermore, when an inspection operation command is issued, it is notified in the car or at the landing, so passengers who accidentally board the car can be warned and the inspection operation can be smoothly started.
