Below in conjunction with accompanying drawing the utility model being carried out detail describes:
Fig. 1 is a structured flowchart of the present utility model.
Fig. 2 is the electrical schematic diagram of the computer controlled embodiment of the utility model.
Fig. 3 is the electrical schematic diagram of the utility model logical control type embodiment.
Fig. 1, Fig. 2 constitute computer controlled embodiment of the present utility model.From Fig. 1, Fig. 2 as can be known, present embodiment is by Microphone MIC, microphone inserts identification circuit 1, microphone on off state identification circuit 2 and processing controller 3 are formed by connecting, microphone inserts identification circuit 1 by Microphone MIC, diode D2, resistance R 5～R7, capacitor C 1 and C3～C4, voltage-stabiliser tube Z1, triode Q3 is formed by connecting, microphone on off state identification circuit 2 is by resistance R 1～R4, capacitor C 2, triode Q1～Q2, diode D1 is formed by connecting, processing controller 3 adopts programmable micro processor CPU, this CPU comprises I/O input CTR1 and CTR2, I/O output OUT, the built-in identification input signal of CPU, the software of output control signal; Wherein MIC connects the base stage of Q3 by D2, Z1, and the collector electrode of Q3 connects the signal input part CTR2 of CPU, and the two ends of R6 connect respectively+tie point of 5V power supply, D2 and Z1; The base stage of Q1 is by R1, R2 connection+5V power supply, the collector electrode of Q1 reaches by R3 connection+5V power supply by the base stage that D1 connects Q2, the base stage of Q1 is by C2 ground connection, and the signal input part CTR1 of CPU connects the collector electrode of Q2, and the signal output part of CPU connects the control end of load L.
