The utility model discloses opening of lift -cabin door can be avoided when the elevator staggered floor, personnel's safety is guaranteed.
Description
Technical field
The utility model relates to elevator safety field, particularly relates to a kind of safe-guard system.
Background technology
Elevator generally has PLC to control, and elevator interior has the mechanism preventing staggered floor from opening the door, and being generally by judging whether this one deck, if arrived, just can opening elevator door, ensures safety.But or elevator can be there is not to this one deck, door but opens, thus causes safety misadventure.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of safe-guard system, solves the problem that elevator staggered floor opens the door.
The utility model is achieved in that a kind of safe-guard system, comprise the first infrarede emitting diode and the second infrarede emitting diode that are arranged in elevator and face elevator opening, and be arranged on the first infrared receiving terminal of lift car upper rear portion and the second infrared receiving terminal of lower backside, the spacing of the first infrarede emitting diode and the second infrarede emitting diode equals the spacing of the first infrared receiving terminal and the second infrared receiving terminal, the positive pole of the first infrarede emitting diode, the positive pole of the second infrarede emitting diode is connected with positive source, the negative pole of the first infrarede emitting diode, the negative pole of the second infrarede emitting diode is connected with power cathode, the power supply anode of the first infrared receiving terminal, the power supply anode of the second infrared receiving terminal is connected with positive source, the power supply negative terminal of the first infrared receiving terminal, the power supply negative terminal of the second infrared receiving terminal is connected with power cathode, the mouth of the first infrared receiving terminal is connected with an input end of door chip, the negative input of the first optocoupler is connected with power cathode, the mouth of the second infrared receiving terminal is connected with another input end of door chip, be connected with the electrode input end of optocoupler with the mouth of door chip, the negative input of optocoupler is connected with power cathode, enabling driving circuit is connected with enabling motor by the mouth of optocoupler.
The utility model tool has the following advantages: can avoid opening of elevator door when elevator staggered floor, ensures the safety of personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model circuit diagram.
Detailed description of the invention
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 and Fig. 2, the utility model provides a kind of safe-guard system, comprise the first infrarede emitting diode 2 and the second infrarede emitting diode 3 being arranged in elevator 1 and facing elevator opening 10, and the spacing being arranged on the first infrared receiving terminal 20 of lift car 4 upper rear portion and the second infrared receiving terminal 30, first infrarede emitting diode of lower backside and the second infrarede emitting diode equals the spacing of the first infrared receiving terminal and the second infrared receiving terminal.As shown in Figure 2, the positive pole of the first infrarede emitting diode D1, the positive pole of the second infrarede emitting diode D2 is connected with positive source, the negative pole of the first infrarede emitting diode, the negative pole of the second infrarede emitting diode is connected with power cathode, the power supply anode of the first infrared receiving terminal U1, the power supply anode of the second infrared receiving terminal U2 is connected with positive source, the power supply negative terminal of the first infrared receiving terminal, the power supply negative terminal of the second infrared receiving terminal is connected with power cathode, the mouth of the first infrared receiving terminal is connected with an input end of door chip U3A, be connected with the electrode input end of optocoupler RL1 with the mouth of door chip, the negative input of optocoupler is connected with power cathode, enabling driving circuit is connected with enabling motor M G1 by the mouth of optocoupler.
Wherein, when elevator cage operation is to perch, namely car is just to opening part, then the light of the first infrarede emitting diode can enter the first infrared receiving terminal, and the light of the second infrarede emitting diode can enter the second infrared receiving terminal, and the first infrared receiving terminal and the second infrared receiving terminal export high level, make to export high level with door chip, the then luminous conducting of optocoupler, the enabling driving circuit of elevator can driven enabling machine operation, and elevator door can be opened.And lift car do not run put in place time, two infrared receiving terminals can not receive infrared light simultaneously, then has an infrared receiving terminal meeting output low level at least, then with door chip output low level, optocoupler is not luminous is off condition, the enabling driving circuit of elevator cannot drive enabling machine operation, and elevator door can not be opened, and ensures safety.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
