Description of drawings
Fig. 1 is a circuit block diagram of the present utility model.
Fig. 2 is the utility model schematic circuit diagram.
Fig. 3 is the workflow diagram of specific implementation windshield wiper controller of the present utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, it shows according to intelligent rain brush controller of the present utility model.It comprises: testing circuit, water spray testing circuit, main control unit circuit, actuating mechanism circuit are set in mu balanced circuit, startup.Wherein the composition of each circuit and principle of work are as follows:
Power supply stabilization circuit links to each other with main control unit, and provides stable power for main control unit; Start and set the input end that testing circuit connects main control unit, main control unit is connected with the Wiper motor of automobile by actuating unit; Input end at main control unit also is connected with the water spray testing circuit.
Described main control unit is made up of common 8 micro controller systems; This singlechip CPU can adopt the micro controller system of existing P IC12C serial model No..
Described startup is set testing circuit and is formed by starting setting detector switch K, current limliting divider resistance R2, filter capacitor C2 and divider resistance R3.During startup work, provide a high potential signal, the notice main control unit after main control unit is analyzed, goes to control rain brush work to actuating unit.During setting work, close actuation signal, promptly provide non-high potential signal, the timing of notice main control unit begins, and after after a while, opens actuation signal, promptly provide high potential signal, set timing this moment and finish, this time value goes to control Wiper motor work to actuating unit after being remembered automatically by main control unit.
Described mu balanced circuit is made up of current-limiting resistance R1, protection diode D1, filter capacitor C1 and zener diode D2, for main control unit provides stable rated voltage.Because automobile voltage floats big, the interference of each systems such as driving engine, starter motor, high-tension coil is strong, therefore, select mu balanced circuit for use after, for total system provides sufficient stable rated voltage, guaranteed the stability of system works.And when total system is not worked, can play the protective effect of power supply reversal connection.
Described water spray testing circuit is made up of water spray detector switch K1, current limliting divider resistance R4, filter capacitor C3 and divider resistance R5.When water spray detected electric potential signal, the notice main control unit after main control unit is analyzed, went to control Wiper motor work to actuating unit.Through repeatedly triggering or continuous trigger after a period of time, be as the criterion with last detected water spray electric potential signal, go to control 5 seconds of Wiper motor continuous working through main control unit to actuating unit, the dirt of removing windscreen when driving a vehicle for the driver provides very big convenience.
Described actuating unit is made up of current-limiting resistance R6, aerotron BG11, relay J, in order to carry out the instruction of main control unit.Its function is the carrying load ability of carrying out the instruction of main control unit, improving anti-interference resistance, enhance system function.
The version of circuit is described particularly below in conjunction with accompanying drawing 2.
Referring to Fig. 2, automobile 12V power supply is introduced R1 one end, the other end of R1 connects the positive pole of D1; The negative pole of D1 connects C1 (C1 other end ground connection); 1 pin of D2 negative pole (D2 positive ground) and CPU; The end of R2 connects to start sets detector switch K, and the other end connects C2 (C2 other end ground connection); R3 (R3 other end ground connection) is connected with 2 pin of CPU; The end of R4 connects water spray detector switch K1, and the other end connects C3 (other end ground connection of C3); R5 (other end ground connection of R5) is connected with 5 pin of CPU; 6 pin of CPU connect the end of R6, and the other end of R6 connects the base stage of BG1 aerotron; 8 pin of the emitter of BG1 aerotron and CPU are ground connection together; The coil of the collector connection relay of BG1 aerotron; The other end of relay coil connects automobile 12V power supply R1 end, coil two ends D3 in parallel (D3 rises and holds the stream protective effect); The contact of relay is connected with the windshield wiper motor.
The mode of operation of above-mentioned rain brush control circuit specifically describes as follows in conjunction with Fig. 3:
Open automobile key switch, connect the 12V automobile power source, voltage regulation unit is powered to CPU, and CPU carries out initialization 256 pre-frequency divisions, 195 countings, base when getting 50MS.Whether be " 1 ", whether when K is not " 1 ", detecting K1 is " 1 " if detecting K simultaneously, when K1 is not " 1 ", gets back to again and detect whether K is one state; When K1 was " 1 ", the cpu instruction actuating unit got back to again whether detection K is one state after brushing for 5 seconds.If raining this moment, when K be " 1 ", brush once and pick up counting, whether detect K simultaneously is " 0 ", when K be not " 0 ", with T=6 second be to send whether instruction back continuation detection K is " 0 " cycle.Whether when K is not " 0 ", detecting K1 is " 1 ", if when K1 is not " 1 ", then get back to T=6 second be the cycle to send instruction; If K1 is when be " 1 ", after carrying out continuously brush and instructing for 5 seconds, get back to T=6 second be the cycle to send instruction.If K is when be " 0 ", T1 picks up counting, and as T1 during greater than 40 seconds, gets back to the state that K1 is " 1 "; When T1 less than 40 seconds, when K is not " 1 ", get back to T1 greater than 40 seconds states, if K be " 1 " and T1 during greater than 2 seconds, then T=T1 is that instruction is sent at the interval with T; As T1 during less than 2 seconds, then make T=2 second, be to send instruction at interval with T.Like this, regulate the intermittence of just realizing 2 seconds to 40 seconds, waits for that simultaneously K is the state of " 0 ", realizes that setting-up time at interval next time.When being not " 0 ", sends K instruction.
The concrete content that limits is preferred embodiment a kind of in the foregoing description, is illustrated as just example at this, can not think restriction of the present utility model.
