The utility model opening or closing of elevator door lock detecting device, it comprises direct supply and a plurality of detecting unit, each detecting unit is made up of electronic components such as stabilivolt, silicon control, field effect transistor, indicator lamps.Total stabilivolt of a direct supply series connection, total stabilivolt two ends button switch in parallel; The series connected successively circuit of the field effect transistor of each detecting unit, resistance, stabilivolt and each detecting unit silicon control, resistance, the series connected successively circuit of indicator lamp are attempted by total stabilivolt (+) and direct supply (-) two ends respectively; The grid correspondence of each field effect transistor places near the fixed end of door lock of elevator circuit switching; Each field effect transistor source electrode connects the silicon controlled control utmost point, each field effect transistor grounded drain; In order to make service personnel in time obtain auditory tone cues, the utility model opening or closing of elevator door lock detecting device also can be at auditory tone cues device of indicator lamp two ends parallel connection; Know the switch position of fault rapidly for the ease of service personnel, the utility model opening or closing of elevator door lock detecting device also can be at floor address code producer of each indicator lamp two ends parallel connection, also can comprise signal converter and telltale, the address code generator output end of the input end of signal converter and each detecting unit links, and its mouth and telltale join.
The fet gate correspondence places near the fixed end of door lock of elevator circuit switching in each detecting unit of the utility model opening or closing of elevator door lock detecting device, there is not direct electric connection with the elevator electric loop, can loop of the door lock and detecting device is isolated when the elevator normal operation.It has simple in structure, and safety is good, and the advantage that cost is low provides convenience for the elevator service personnel, efficiently the instrument of detecting gate lock-switch fault.
Description of drawings
Fig. 1 is the utility model circuit diagram.S1, S2, S3......Sn represent each layer door switch in the door lock of elevator loop.
Specific embodiment
In conjunction with Fig. 1 connection of the present utility model is described: establish the total n layer of elevator.Silicon control BT169, power supply direct current 12V, stabilivolt 2CW6.2V, field effect transistor 3DJ6D.
(-) with the total stabilivolt 2CW6.2V of another termination of 12V power supply (+) power connection K switch, source switch K, total stabilivolt 2CW6.2V two ends button switch AN in parallel, total stabilivolt 2CW6.2V (+) meets indicator lamp LED1, LED2, LED3 ... the end of LEDn; Meeting each detecting unit stabilivolt 2CW6.2V is W1 (-), W2 (-), W3 (-) ... Wn (-); Each detecting unit stabilivolt 2CW6.2V is W1 (+).W2 (+), it is DJ1 that W3 (+) ... Wn (+) connects the resistance R 1 of each detecting unit respectively, the other end of each detecting unit resistance R 1 meet each detecting unit field effect transistor 3DJ6D respectively, DJ2, the source electrode of DJ3......DJn; Each detecting unit indicator lamp LED1, LED2, the other end of LED3......LEDn connect each detecting unit resistance R 3 respectively, and it is SCR1 (+) that the other end of R3 meets each detecting unit silicon control BT169 respectively, SCR2 (+), SCR3 (+) ... SCRn (+).Each detecting unit silicon control BT169 is SCR1 (-), SCR2 (-), SCR3 (-) ... SCRn (-) power connection (-).The control utmost point of each detecting unit silicon control BT169 connects the source electrode of field effect transistor 3DJ6D, connects C1 one end, the other end power connection (-) of the drain electrode of field effect transistor 3DJ6D and C1.The grid correspondence of field effect transistor 3DJ6D places near the fixed end of door lock of elevator loop each layer switch.With to the distance of switch fixed end less than being as the criterion to switch movable end distance, avoid under the open circuited situation of switch, sensing the electric field of switch movable end.
Independence and safety when guaranteeing the loop of the door lock normal operation, detection cell circuit and door lock electric loop are not have direct coupled on electric.So just guaranteed the inherent characteristic of loop of the door lock.
Principle of work: circuit of this detecting device and door lock of elevator loop do not have and anyly directly are electrically connected, and it is to judge the break-make of switch by detecting near the variation of the electric field electrified wire, has fundamentally avoided the influence to the door lock of elevator loop.S1, S2, Sn are respectively the door lock electric switches on elevator one deck, two layers, n layer elevator door, when the elevator normal operation, when the layer door at these door switch places closed, the door switch conducting, the current potential of switch ends equates, the grid that is fixed near the detecting unit field effect transistor switch one end just can detected electric field, field effect transistor source electrode, drain electrode pinch off, and the resistance between source electrode, the drain electrode becomes big.K is a source switch, be in off-state at ordinary times, the power turn-on K switch, detecting device just is in readiness for action, AN is a test button, it is connected in parallel on the two ends of total stabilivolt W, the voltage stabilizing value of W is 6.2V, this stabilivolt mainly carries out step-down during standby, with W1, W2, Wn matches and makes the voltage of the silicon controlled control utmost point is zero, avoid silicon control when not pressing test button AN, to be triggered. press test button AN, total stabilivolt W is by short circuit, W1, W2, voltage on the negative pole of Wn and the positive pole of LED just has been raised to about 12V from about 6V, near the closed contact actuating switch detecting unit, fet gate is owing to sense actuating switch one end electric field on every side, the source of cooresponding field effect transistor, the drain electrode pinch off, it is big that resistance becomes, it is big that pressure drop on it also becomes, the conducting after obtaining trigger voltage of the SCR control utmost point of corresponding detecting unit, the light-emitting diode of corresponding detecting unit is lighted, according to the silicon controlled characteristic, silicon control after the conducting just remains on the state of conducting, unclamp test button AN, then the state of each detecting unit luminotron just is held, and also can not change before pressing test button AN next time again.At this moment service personnel just could back down the led status that elevator is checked each layer to sedan-chair with loop of the door lock behind the machine room short circuit, and there is the fault of not conducting in the door switch of that one deck that indicator lamp does not work, repairs to get final product that (indicator lamp that attention is adjacent is bright! ), the source switch K of shutoff detecting device after repair is finished turn-offs the silicon control in all detecting units, for next detection failure is got ready.So, service personnel just can find the door switch of et out of order rapidly easily, takes a machine testing apart and need not successively stop, and has improved efficient greatly.Service personnel if the signal of each indicator lamp is delivered to machine room, or carries out signal conditioning, just can be known the position of fault door switch before entering the hoistway repair by the circuit of encoding and decoding.
