The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
Referring to Fig. 1, a kind of safety control circuit of apparatus for controlling elevator comprises interconnective power circuit, switch circuit, safety return circuit and fault show circuit.Described power circuit comprises feeder ear B05 and ground terminal B04; Described switch circuit is made up of a plurality of safety switchs relevant with elevator each several part running state, when elevator generation operating troubles, and described safety switch effect; Described safety return circuit guarantees to do when the safety switch of elevator the stoppage protection of time spent elevator; Described fault show circuit is used to show failure code.
Described a plurality of safety switch is in normally off and is connected between the feeder ear B05 and ground terminal B04 of described power circuit behind the polyphone successively, also is connected with the safety return circuit contactless switch of often opening between the series circuit of described safety switch and the described ground terminal B04.When the elevator normal operation, all safety switchs are all closed, and then described safety return circuit contactless switch both sides have the voltage difference between described feeder ear B05 and the ground terminal B04; When Lift out of order, certain or a plurality of safety switch disconnect, and then described safety return circuit contactless switch both sides voltage is 0.
Referring to Fig. 3, Fig. 4, the end of the close described ground terminal B04 of each described safety switch all has lead to be connected with described fault show circuit, and also be provided with optocoupler between every lead and the described fault show circuit, the disconnection that is electrically connected with the two prevents to interfere with each other.
When the elevator normal operation, the end of the close described ground terminal B04 of each described safety switch is high level, and the mouth of described optocoupler is all put low; When elevator breaks down, described safety switch is done the time spent, one of the close described ground terminal B04 of this safety switch makes a clean sweep of the equal power down of other safety switch of a side that electricity is the close described ground terminal B04 of low level and this safety switch and is low level, put height with the corresponding bonded assembly optocoupler of these low levels, micro controller system in the fault show circuit receives the signal change of optocoupler, shows 3 digital fault code with decoding after the signal encoding and at the read out instrument place.This switch circuit and fault show circuit have preceence, has preceence for safety switch near described feeder ear B05 one side, that is: when two or more safety switchs disconnected simultaneously, what read out instrument showed was the pairing failure code of safety switch at close described feeder ear B05 place.
