Description
The utility model relates to a kind of photoelectric control switch.
In the prior art, photoelectric control switch generally comprises transducing part and control section, transducing part separates with control section, the two lead-in wire by conducted signal connects, the photoelectric sensing part is placed on light variation place (as open-air) usually, since connect that two-part lead-in wire transmits be very weak be photosignal, so this lead-in wire very easily is subjected to external interference, thereby make the reliability variation of overall optical electric control switch.
The purpose of this utility model is to provide a kind of photoelectric controller of high reliability.
The technical solution of the utility model is: the utility model comprises a photoelectric sensor that changes output voltage according to extraneous light; A reference voltage that produces direct voltage; A voltage comparator that is used for the voltage of comparison photoelectric sensor and reference voltage and exports a significant level; The two-way delay circuit that the level signal of voltage comparator output is delayed time; The relay drive circuit that the level signal of two-way delay circuit output is carried out power amplification; Action actuating mechanism according to the level control relay contact action of relay drive circuit output.Voltage comparator is compared the voltage of photoelectric sensor output with reference voltage, when the voltage of photoelectric sensor output during greater than reference voltage, level of voltage comparator output, this level is after two-way delay circuit time-delay, coil by the relay drive circuit control relay gets electric (or dead electricity), makes the corresponding relays contact move.When the voltage of photoelectric sensor output is lower than reference voltage, voltage comparator is exported another level, this level is after two-way delay circuit time-delay, and the coil losing electricity (or getting) by the relay drive circuit control relay makes the corresponding relays contact move.
The utility model compared with prior art has following advantage:
(1). by regulating the variable resistor in the photoelectric sensor, can make the sensitivity of photoelectric controller adjustable continuously, thereby be fit to different occasions.
(2). owing to be provided with two-way delay circuit, relay such as (for example lightning) is not shaken when light suddenlys change, and has improved reliability.
(3). be switched on or switched off power supply by relay, so can drive powerful electrical equipment.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is a circuit block diagram of the present utility model;
Accompanying drawing 2 is circuit theory diagrams of the present utility model;
In the accompanying drawing 1,1 is photoelectric sensor; 2 is reference voltage; 3 is voltage comparator; 4 is two-way delay circuit; 5 is relay drive circuit; 6 is action actuating mechanism.In the accompanying drawing 2, photoelectric cell 10 is formed photoelectric sensor 1 with variable resistor 11, changes the resistance of variable resistor 11, can regulate the sensitivity of photoelectric sensor.Form reference voltage 2 by resistance 12 and voltage-stabiliser tube 13.Be that 555 time-base circuit is as voltage comparator 3 by model, wherein 71 be first pin of this integrated package, 72 is second pin of this integrated package, 73 is the 3rd pin of this integrated package, 74 is the 4th pin of this integrated package, 75 is the 5th pin of this integrated package, and 76 is the 6th pin of this integrated package, and 78 is the 8th pin of this integrated package.Two-way delay circuit 4 comprises resistance 14, resistance 15, diode 16 and electric capacity 17; Resistance 15 is with in parallel with resistance 14 again after diode 16 is connected, the contact of resistance 14 and resistance 15 is as the input of two-way delay circuit 4, the contact of resistance 14 and diode 16 is as the output of two-way delay circuit 4, and cross-over connection has electric capacity 17 between this output and the power supply ground.Relay drive circuit 5 is made up of by 555 time-base circuit model.Wherein 81 be first pin of this integrated package, 82 is second pin of this integrated package, 83 is the 3rd pin of this integrated package, 84 is the 4th pin of this integrated package, 85 is the 5th pin of this integrated package, and 86 is the 6th pin of this integrated package, and 88 is the 8th pin of this integrated package.Action actuating mechanism 6 mainly comprises relay coil 18, indication diode 19 and relay contact 27.When extraneous light grow, the resistance of photo resistance 10 diminishes, 72, the current potential at 76 two ends uprises and greater than the current potential (current potential of 75 ends is 6 volts) of 75 ends, this moment, 73 ends became low level, electric capacity 17 is by resistance 14,73 ends, the discharge of 71 ends, when electric capacity 17 discharges into 86,82 ends and is lower than 2 volts, the upset becoming of 83 ends high level, relay coil 18 dead electricity.When light is dark, it is big that the resistance of photo resistance 10 becomes, 72, the current potential step-down at 76 two ends (less than 2 volts) and be lower than 75 ends, 73 ends upset becoming high potential, power supply gives electric capacity 17 chargings by 74 ends, 73 ends, resistance 15, diode 16, when charging to 82,86 terminal potentials greater than 8 volts, the upset of 83 ends becomes low level, relay coil 18 electric while diode 19 is bright, relay contact 27 actions make bulb 28 by binding post 29 energized.9 is integrated package of pressure-stabilizing, and its model is 7812.Alternating current is delivered to transformer 26 by binding post 29 with alternating voltage, behind the bridge rectifier via diode 22,23,24,25 compositions, passes through electric capacity 21,20 filtering and integrated package 9 voltage stabilizings again, and output DC is for photoelectric controller provides power supply.
Because electric capacity 17 is in when charging, 86 ends will be when 0 volt rises to 8 volts 83 ends level just occurs and overturn; And electric capacity 17 is when discharge, the level upset appearred in 83 ends when 86 ends were reduced to 2 volts by 8 volts, and for no matter the level that makes 73 ends is to uprise or step-down, 86 ends all can obtain identical delay time, so used diode 16,14 to be slightly larger than resistance 15 as its resistance of discharge resistance.
