Description
Technical field
The utility model relates to a kind of reflective Infrared Automatic Controller.
Background technology
At present, various reflective Infrared Automatic Controller structures are numerous.Like Chinese patent " a kind of controller of ultra-low power consumption infrared sensor trash bin " proposed for No. 201010108483.9.In this technical scheme, controller of ultra-low power consumption infrared sensor trash bin comprises single-chip microcomputer, is connected with infrared induction circuit and power supply on the described single-chip microcomputer respectively.The infrared induction circuit comprises infrared emission circuit and infrared receiving circuit; Infrared receiving circuit is made up of receiving tube, one-level amplifying circuit, second amplifying circuit, waveform shaping circuit, waveform negative circuit, receiving circuit power supply; And receiving tube, one-level amplifying circuit, second amplifying circuit, waveform shaping circuit, waveform negative circuit connect successively; Waveform negative circuit output is connected with single-chip microcomputer; The receiving circuit power supply is connected with single-chip microcomputer, is connected with motor on the output of single-chip microcomputer.But not enough below existing: because single-chip microcomputer adopts dynamic operation mode, per four cycles are carried out an instruction, and therefore the work that goes round and begins again, have relatively high expectations to peripheral electrical environment, very easily receives outside electromagnetic interference, easily by thunder and lightning critical defect such as break.
Summary of the invention
The purpose of the utility model is: a kind of working stability, reflective Infrared Automatic Controller that reliability is high are provided.
The utility model is realized through following technical scheme:
A kind of reflective Infrared Automatic Controller comprises: infrared emission receiving circuit, signal receiving circuit, control circuit, drive circuit and motor; It is characterized in that: described infrared emission, receiving circuit comprise: IC1, BG8, BG7, R2, R1, IC2, R3, R4; Described control circuit comprises: R5, C2, IC3-1, R6, IC4-1, R7, C3, IC4-2, R8, IC3-3, R9; Described drive circuit comprises: R14, R10, BG1, R12, BG2, BG4, BG3, BG5, BG6, R13.
The advantage of the utility model is: because the utility model adopts bistable circuit, and need not single-chip microcomputer, peripheral electrical environment is required low, be not vulnerable to outside electromagnetic interference, make reflective Infrared Automatic Controller working stability, reliability high.
Description of drawings:
Fig. 1 is the circuit diagram of the reflective Infrared Automatic Controller of the utility model.
Embodiment:
As shown in Figure 1: the reflective Infrared Automatic Controller of present embodiment comprises:: infrared emission receiving circuit, signal receiving circuit, control circuit, drive circuit and motor M.Described infrared emission, receiving circuit comprise: IC1, BG8, BG7, R2, R1, IC2, R3, R4; Described control circuit comprises: R5, C2, IC3-1, R6, IC4-1, R7, C3, IC4-2, R8, IC3-3, R9; Described drive circuit comprises: R14, R10, BG1, R12, BG2, BG4, BG3, BG5, BG6, R13.
The course of work of present embodiment is following: as people or thing when infrared emission receives an IC2 front-reflection infrared signal; Infrared receiving terminal IC2 receives that infrared signal delivers to the CP end of IC4-1; Make the bistable circuit upset; Q1 exports high level, and one the tunnel through R14, BG6, R13, BG5, BG4 conducting, and drive motors M just changes.When another route R5 was charged to 2/3VCC voltage to C2, IC3-1 exported a high level, to the R pin zero clearing of IC4-1.The backspace initial condition.Q1 stops actuating motor after being zero.
Q1The output high level, when R7 was charged to 2/3VCC voltage to C3, IC3-2 exported a high level, and the CP end to IC4 makes the bistable circuit upset, and Q2 exports high level, through R10, BG1, BG12, BG2, BG3 conducting, drive motors M counter-rotating.When Q2 output high level, when R9 was charged to 2/3VCC voltage to C4, IC3-3 exported a high level, to the R pin zero clearing of IC4-2; The execution reverse motors is stopped.
