It features that a detection circuit can examine at any time if the safety citcuit of elevator is in normal state and the failure signal collector can be used for in-line detection of elevator to determine if it is electrically powered and levelled with floor, or if the band brake is opened, or if it is in maintenance state. Its advantages are simplified failure detection, high safety and high automation level.
Description
The present invention relates to a kind of elevator faults and detect and rescue mode, it detects the safe condition of elevator at any time in the elevator normal course of operation, carries out the emergency method that rescue is judged and automatically performed to failure analysis when taking place to be stranded ladder.
The elevator faults emergency method is to be used for elevator is broken down when take place being stranded ladder, carries out analysis and judgement, and control backup power power supply after confirming fault makes elevator open car door, rescue passenger to nearest floor.In the prior art, in order when elevator breaks down, in time to save the passenger, people have designed various elevator faults emergency facilitys, what have can only report to the police, can not save oneself, though and saving oneself of having, but detection to fault, be that the pointwise of elevator control path is detected, be applicable to the elevator control path that simple discrete component constitutes, then powerless for PC ladder, large-scale integration circuit.
Chinese patent discloses for No. 90107478 a kind of " elevator faults and power failure flat-layer technique and equipment ", it utilizes gets rid of the original control system of elevator, the direct method that elevator master motor, electromagnetic brake coil, switch lift car door motor are controlled, when elevator breaks down or have a power failure, as long as click emergency switch, backup power send to controller immediately.Controller after the energising at first makes the electromagnetic brake coil of former elevator and primary circuit disconnect, and connects to such an extent that open a sluice gate after electric with backup power, meanwhile makes main motor get electric startup and is being with the car flat bed.When car arrives near level position, electromagnetic brake coil band-type brake, main motor outage quits work, meanwhile switch lift car door motor gets, open the door and put the people, it not only can not detection failure, and no matter emergency switch is located in the car still outside the car, all there is very big safety hazard, as: be located at passenger's possibility misoperation in the car; Be located at car outer may be when being stranded ladder unmanned the discovery, some faults to national regulation do not allow the situation of emergency facility rescue can rescue because of judging yet simultaneously, this method may cause causing danger.
The objective of the invention is to utilize various faults finally show power supply whether have electricity, car whether flat bed, whether be in inspecting state, whether open four kinds of factors of band-type brake, carry out comprehensive analyses, automatically perform the fault emergency method of rescue after the affirmation fault.
The object of the present invention is achieved like this: a kind of automatic online detection helping method for elevator faults, do not change the elevator control path, when elevator breaks down, power supply is isolated in system control cpu control, and control backup power by system control cpu and power to hoisting motor, electromagnetic brake coil and car door electrical motor, elevator moves to leveling zone, opens car door, it is characterized in that:
A, it also has one to forbid carrying out the whether signal input system control cpu of normal condition of gate interlock loop, safety return circuit and " normal/maintenance " state switching circuit that the rescue signal testing circuit detects elevator at any time;
B, system control cpu also the power supply by the final performance of the online detection elevator faults of lift fault signal Acquisition Circuit whether have electricity, car whether flat bed, whether open band-type brake and whether be in the signal of four factors of inspecting state, whether the comprehensive analyses elevator breaks down;
C, when elevator take place to be stranded ladder, if detecting, step a forbids carrying out rescue when being non-normal state signal, system control cpu is after passing through step b line detection signal and comprehensive analyses when being normal state signal if detect, and the power supply of control backup power automatically performs rescue.
The power supply of the final performance of the various faults of the online detection elevator of the present invention whether have electricity, car whether flat bed, whether open band-type brake and whether be in the set signalling comprehensive of four factors of inspecting state, elevator faults is detected oversimplifies, applied widely; Opposite house interlock circuit, safety return circuit fault judgement are also carried out rescue when forbidding occurring this class fault, and the safety control performance is good; The power supply of system control cpu control backup power automatically performs rescue, the degree of automation height.
Below in conjunction with accompanying drawing most preferred embodiment of the present invention is elaborated:
