The present invention relates to an elevator for disabled persons operating under control of a micro-processor, and in particular, in case of an emergency in which an emergency stop occurs between floors and floors, rather than a normal arrival floor, while the elevator is operating a plurality of floors. The present invention relates to an automatic rescue operation method for an elevator for a delayed bar free elevator, which performs an automatic rescue operation on a floor having a HALL side call.

Conventional free hand elevators have problems with the position detector (PM, Positector) attached to the upper part of a car during normal operation of multiple floors in a hoistway, problems with normal safety operation of the elevator, or deceleration of the target floor. If the fault of the motor control signal (SCR device) for slowing down the rated driving speed of the elevator from the point occurs and emergency stop between floor and floor, check whether the emergency stop floor is the lowest floor. Passengers will be evacuated by low-speed rescue operation to the upper floor and emergency stop by driving the elevator down to the lowest floor if not the lowest floor.

However, the stopping of the elevator at the top floor was not stopped at the stop point of the stop floor correctly by the normal deceleration command signal, so that the passengers who were delayed had considerable difficulty when getting off the train.

Therefore, the present invention is to improve the above-mentioned disadvantages by controlling the elevator with a microprocessor, when the emergency stop between the floors and floors during the operation of the elevator unconditional operation without the automatic rescue operation to the bottom floor unconditionally the hall side call registration is The automatic rescue operation is performed to the generated ground floor so that even if the elevator does not stop at the exact landing position, the passengers who are delayed can be safely evacuated with the help of the passengers waiting in the hall.

The automatic rescue operation apparatus of the conventional retard free elevator is as follows.

As shown in FIG. 1, the contact Rxb of the elevator operation check relay to which the positive power (+) is applied is connected to the contact RYb of the door open area check relay, and the door open area check relay contact RYb is negative. Connect to the ground-floor automatic rescue operation command relay (R1) to which power (-) is applied, and connect the movable vehicle (Fx) for each floor detection detection with positive power (+) to various confirmation detection stators (M1-MN). Connected to each floor confirmation relay (R21… R2N) to which negative power (-) is applied, and the automatic rescue operation command relay contact (R1a) to which the positive power (+) is applied to each floor confirmation relay contact (R21a). The relay contact R21a is connected to the rising operation command relay R3 to which negative power (-) is applied, and the falling operation command relay R4 to which negative power (-) is applied through each floor confirmation relay contact R21b. To the positive power supply Connect the up operation command relay contact R3a to the up direction operation relay R5 to which negative power supply (-) is applied, and the down operation command relay contact R4b to which positive power supply (+) is applied to the negative power supply (-). It is a configuration connected to the applied down direction operation relay (R6).

As described above, the automatic rescue operation device is excited only when the elevator is in operation and released when it is stopped when an elevator operating multiple floors is emergencyly stopped between floors due to a defective position detector or motor controller. The relay (RXb) of the operation command relay, which is a relay, is turned on, the contact (RYb) of the door open area confirmation relay, which is a relay that is excited in the elevator's door open area and released in a non-door open area, is turned on and is automatically rescued. Since the command relay R1 is excited, the emergency stop elevator is automatically rescued to the bottom floor.

At this time, if each floor confirmation detection vehicle Fx attached to the floor controller is operated with the lowest floor stator M1 in the emergency stop state, that is, if the emergency floor is stopped at the lowest floor, the lowest floor detection relay R21 is excited and automatically rescued. The rising driving command relay R3 is excited through the driving command relay contact R1a and the lowest detection relay contact R21a.

Therefore, the contact R3a of the ascending operation command relay R3 is turned on, and the ascending operation relay R5 is excited, so that the emergency stop elevator automatically performs the rescue operation to the top floor, the first floor of the lowest floor, and the emergency stop elevator. The lower floor detection relay R21 is released when the movable vehicle Fx for detecting each floor attached to the floor controller is operated with the stator M2-MN of the floor controller of other floors other than the lower floor stator M1. do.

In addition, when the elevator is emergencyly stopped on the other floor instead of the lowest floor, the falling operation command relay R4 is excited through the contact R1a of the automatic rescue operation command relay R1 and the contact R21b of the lowest floor detection relay R21. At the same time, since the contact point R4a of the falling operation command relay R4 is turned on, the falling direction driving relay R6 is excited and the elevator is automatically switched from the emergency stop floor to the lowest floor, which is the first floor.

Therefore, if the emergency free elevator stops emergencyly between floors and floors, it automatically rescues the first floor and the other floors if it is the lowest floor, so that the elevator is evacuated to the lowest floor. As a result, passengers who are incapacitated in wheelchairs have a defect that is difficult to evacuate without getting the help of others when getting off the train.

Input the "low" signal and the hole rising and falling call registration relay 13, the data value of the input hall call registration signal is transmitted to the operation central processing unit 11 through the data bus 18, the operation central processing Since the main program of the device 11 is programmed to drive the elevator by the hall call signal value, the rescue operation is performed automatically. A more detailed description according to the flowchart of FIG. 4 is as follows.

When the emergency free elevators operating multiple floors stop emergencyly between floors, the program counter of the main program of the CPU 11 is a part of the main program during the execution of the main program. The display moves to the low speed operation program (EREXIT). At this time, the low speed operation program (EREXIT) is an abnormal operation of the elevator, so the main program takes control of the contactor drive circuit that operates as a command of the motor program in the normal state, and the low speed operation, which is a kind of label display as part of the main program, The low-speed operation mode called the program SLNDFx is moved. The low speed operation program (SLMDFx) checks for the presence of the normal door opening area for emergency freely disabled elevators and automatically rescues the first floor above the lowest floor if the door is not open or the lowest floor if it is not the lowest floor.

At this time, the subroutine ascending calling search (AVVBSH), which checks the hall calling registration signal of the local floor or more, is called to determine whether or not the hall calling registration signal is higher than the number of floors currently emergency stopped. Any hall call registration signal data value from the first layer to the uppermost layer is input into the memory of the upper call finder. When the data value of the current layer number is compared with the uppermost layer, it is called "layer aberration (K)". The data value of the smallest floor number (K) is determined as the driving floor (FLNO) by sequentially entering the memory area.The main program generates a low-speed rising operation command (SU) in the motor program so that the rising ramp is turned on and the hall call registration signal Automatic rescue operation is performed on the generated floor.

In addition, if the hole upcall registration signal does not occur in the subroutine called up call search (AVBSH), the low speed operation program (SLMDFX) calls the subroutine called the lower call search to stop the current emergency. If there is a hall call registration signal on the hall side of the number of floors or less, and there is a hall call registration signal, an arbitrary hall call registration signal data value of one layer from the lowest layer to the current layer number is input to the descending call finder (DHC) memory. Compared to the current floor number data value (LVL), it is sequentially input into the memory area called "floor aberration (K)", and the lowest floor number (K) data value is determined as the driving floor (FLNo) so that the falling ramp is turned on and the motor program The low-speed descent operation command (SD) is generated during the automatic rescue operation to the floor on which the hall call registration signal is generated.

However, if no hall call signal is registered in any of the subroutines of the upcall search (AVBSH) and the downcall search (LWRSH), check whether the current emergency stop floor is the lowest floor, and if it is not the lowest floor, slow down the operation in the motor program. When the command SD is generated and the lowest floor is generated, the low-speed rising operation command SU signal is generated to automatically rescue the elevator to the lowest floor.

That is, when the emergency stop elevator stops in the normal door opening area, the door is opened without opening the door unconditionally and according to the presence or absence of the call signal registration signal on the emergency stop floor, the door is opened. If not, the lift calling search (AVBSH) It is moved to the subroutine of and operates according to the flowchart.

Therefore, the automatic rescue operation apparatus according to the present invention performs the automatic rescue operation to the lowest floor where the call registration on the hall side occurs when the elevator makes an emergency stop between floors while the elevator is operating a plurality of floors so that the elevator stops at the correct landing position. Even if you do not have the advantage of being able to evacuate the passengers who are free of delay by the help of the passengers waiting in the hall. Reference numeral 2 denotes a shield plate 3, a rising position detector 4 is a falling position detector, and 5 is a hoisting vehicle.
