Embodiment
As shown in Figure 1.A kind of Brain health instrument deflation control circuit, include microprocessor ATmega8, and the air pump QB to be controlled by microprocessor ATmega8 and a pair air valve QF1, QF2, 9 pin of microprocessor ATmega8, crystal oscillation circuit is connected between 10 pin, 11 pin access a triode Q4 base stage by resistance R30, 12 pin access a triode Q3 base stage by resistance R29, triode Q3, push-button switch S2 ground connection is accessed again after Q4 emitter connects altogether, air valve QF1 terminal are connected with triode Q3 collector electrode, air valve QF2 terminal are connected with triode Q4 collector electrode, and air valve QF1 and QF2 separately another terminal connect rear access 12V voltage altogether, electric capacity C10 parallel with one another is also connected between air valve QF1 two terminal, diode D7, electric capacity C11 parallel with one another is also connected between air valve QF2 two terminal, diode D8, 13 pin of microprocessor ATmega8 access the base stage of a triode Q2 by resistance R10, the grounded-emitter connection of triode Q2, collector electrode and air pump terminal are connected, another wiring of air pump termination 12V voltage, electric capacity C12 parallel with one another, diode D9 is also connected between air pump two terminal, 15 pin of microprocessor ATmega8,16 pin are as load incoming end, 23 pin, 24 pin, 25 pin, 26 pin are as FPDP, the 7 pin access 5V voltages of microprocessor ATmega8,20 pin are by LC eliminator access 5V voltage.
Crystal oscillation circuit comprises crystal oscillator M, and be connected to ground connection after electric capacity C6, C7 parallel with one another between crystal oscillator M two ends, 9 pin, 10 pin of microprocessor ATmega8 are connected with crystal oscillator M two ends respectively.
LC eliminator comprises 20 pin of one end access microprocessor ATmega8, the inductance L 1 of the other end access 5V voltage, by electric capacity C8, C9 ground connection parallel with one another between inductance L 1 and 20 pin of microprocessor ATmega8, inductance L 1 and electric capacity C8, C9 form LC eliminator.
In the present invention, microprocessor Atmega8 9 pin, 10 pin connect crystal oscillation circuit, 7 pin connect direct current 5V voltage, LC eliminator need be connect during 20 pin access direct current 5V voltage, 22 pin, 8 pin ground connection, 23,24,25,26 pin be FPDP be used for Rcv decoder export signal, 15 pin, 16 pin connect load, the prime time of control load, weak shelves.11 pin, 12 pin connect a road air valve control circuit respectively, and 13 pin connect air pump control circuit.
The gentle pump control circuit of air valve control circuit voltage used is direct current 12V.When microprocessor Atmega8 receives starting-up signal from decoder, by software programming to FPDP 13 pin high level, by a base resistance R10 to triode Q2(D882) base stage, triode Q2(D882) conducting, in running order, air pump control circuit forms loop, and air pump starts inflating pressure.An air pump electric capacity C12 in parallel and diode D9, C12 eliminate the spark energy produced in air pump rotary course, and diode D9 eliminates in air pump rotary course the adverse consequences producing induction electromotive force and cause, and makes air pump stable working state.
