As shown in Figure 1, when layer door switch S1-----Sn is connected in layer loop of the door lock 2, power supply 4 is given two of the layer loop of the door lock 2 of master board to detect input end 3 by layer loop of the door lock 2 and is powered, when any one switch in layer door switch S1-----Sn disconnects, two of layer loop of the door lock 2 detection input ends 3 all can not be made to obtain the electric signal of power supply 4.
When the detection input end 3 of two on elevator-mainboard is detection input ends 3 of layer loop of the door lock 2, each layer of door lock there is a layer door switch Sx, several layers of door switch S1-----Sn are cascade, when power supply 4 Direct driver layer loop of the door lock 2 detects input end, layer door switch S1----Sn is in closed conducting state, when certain layer of door switch Sx disconnects, detect by two the voltage that input end 3 can not detect power supply 4, elevator-mainboard quits work.
For this kind of mode, although ensure that the safety that elevator runs, but the weak point of this direct-drive type safety return circuit is any one or the several disconnection in layer door switch S1---Sn all can make detection input end 3 voltage of power supply 4 can not be detected, elevator-mainboard quits work, can not knowing it is which layer door switch Sx disconnects at once, when investigating fault, needing the layer door switch S1---Sn of floor one by one to check, investigation difficulty is high, time-consumingly takes a lot of work; How when circuit goes wrong, can know rapidly that fault has appearred in which link, and under the prerequisite not reducing elevator safety, demonstrate position of failure point, accelerate the work efficiency improving failture evacuation, reduce failture evacuation difficulty, thus compensate for the deficiencies in the prior art.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of craspedodrome elevator door to lock coupling safety return circuit, pass through the technical program, multiple elevator door lock-switch circuit of direct-drive type safety return circuit are set to multiple elevator door lock loop, between each adjacent elevator door lock loop, coupling transformer is set respectively, form multistage coupling safety return circuit, thus each elevator door lock loop carries out direct current segmentation, and on each elevator door lock loop luminous element in parallel, when detecting, by the luminous situation of the luminous element of diverse location, just can judge the safety that craspedodrome elevator door is locked fast, have during fault and also can show out of order general location.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of craspedodrome elevator door lock coupling safety return circuit, comprise power supply, the layer door switch of door lock measure loop and several floor, described door lock measure loop is respectively arranged with luminous indicating lamp and two detection input ends, comprise coupling transformer and luminous element, described coupling transformer and luminous element are respectively several, each coupling transformer is separately positioned between corresponding two adjacent layer door switcies, make the layer door switch between two coupling transformers by the coupling transformer constituting layer door switch independently Sx link circuit of both sides, be positioned at the layer door switch Sn of the top, detect input end by two on door lock measure loop and form Sn link circuit, be positioned at layer door switch S1 and the electric power generating composition S1 link circuit of bottom, described S1 link circuit and several Sx link circuit are connected in parallel to luminous element respectively.
Beneficial effect after employing technique scheme is: one passes through the technical program, multiple elevator door lock-switch circuit of direct-drive type safety return circuit are set to multiple elevator door lock loop, between each adjacent elevator door lock loop, coupling transformer is set respectively, form multistage coupling safety return circuit, thus each elevator door lock loop carries out direct current segmentation, and on each elevator door lock loop luminous element in parallel, when detecting, by the luminous situation of the luminous element of diverse location, just can judge the safety that craspedodrome elevator door is locked fast, have during fault and also can show out of order general location.
Accompanying drawing explanation

Fig. 2 is the multistage coupling safety return circuit of the utility model middle level door switch.
In figure, 1 door lock measure loop, 2 layers of loop of the door lock, 3 detection input end, 4 power supplys, 5 luminous indicating lamps, 6 coupling transformers, 7Sx link circuit, 8S1 link circuit, 9Sn link circuit, S1-----Sn layer door switch, L1-----Ln luminous element.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment in the utility model is described in further detail.
As shown in Figure 2, the craspedodrome elevator door lock coupling safety return circuit that the utility model relates to, comprise power supply 4, the layer door switch S1-----Sn of door lock measure loop 1 and several floor, described door lock measure loop 2 is respectively arranged with luminous indicating lamp and two detection input ends 3, comprise coupling transformer 6 and luminous element L1-----Ln, described coupling transformer 6 and luminous element L1-----Ln are respectively several, each coupling transformer 6 is separately positioned between corresponding two adjacent layer door switch Sx (for any one in S1----Sn), make the layer door switch Sx between two coupling transformers 6 by the coupling transformer 6 constituting layer door switch Sx independently Sx link circuit 7 of both sides, be positioned at the layer door switch Sn of the top, detect input end 3 by two on door lock measure loop 1 and form Sn link circuit 9, the layer door switch S1 and the power supply 4 that are positioned at bottom form S1 link circuit 8, described S1 link circuit 8 and several Sx link circuit are connected in parallel to luminous element L1-----Ln respectively.
The utility model adopts multistage coupling safety return circuit, described S1 link circuit 8, Sn link circuit 9 and several Sx link circuit 7, be divided into separately independently S1 link circuit 8, Sn link circuit 9 and several Sx link circuit by coupling transformer 6 by each junction circuit.
When the layer door of floor detects during door lock measure loop 1 is to multistage coupling safety return circuit, have following several situation.
1. when a layer door switch S1-----Sn is all in serviceable condition, the detection input end 3 of door lock measure loop 1 is connected with Sn link circuit 9, power supply 4 in S1 link circuit 8 leads to, power supply 4 electric signal is by coupling transformer 6, be connected with door lock measure loop 1 through several Sx link circuit 7, Sn link circuit 9, the whole conducting of luminous element L1-----Ln be positioned on luminous indicating lamp 5 on door lock measure loop 1 and several Sx link circuit 7 and S1 link circuit 8 is luminous.
2. when layer door switch S1 is in faulty condition, luminous indicating lamp 5 and luminous element L1-----Ln are all not luminous, can learn that a layer door switch S1 has problem fast by analyzing.
3., when layer door switch Sx is in faulty condition, luminous indicating lamp 5 and luminous element Lx to luminous element Ln can not be luminous, can learn that a layer door switch Sx has problem fast by analyzing.
In the utility model, in any one layer of door switch Sx any one or several break down disconnect time, the detection input end 3 of door lock measure loop 1 can be made the voltage of power supply 4 can not to be detected, elevator-mainboard is quit work, thus actv. has ensured the safety of craspedodrome elevator, and the luminous element Lx to luminous element Ln that distance detects between input end 3 fault layer door switch Sx to check point farthest can not be luminous, during investigation fault, Sx link circuit 7 position of the place layer door according to luminous element Lx starts investigation, after fault restoration, luminous element Lx corresponding to This floor just recovers to light, by that analogy, progressively repair, until all investigation is complete.
The above, be only better possible embodiments of the present utility model, and be not used to limit scope of the present utility model.
