When a plug is to be inserted into the socket, touch pressing self-resetting switch S1 conducting, the 3rd comparator chip U3 and LM393 positive input are high level, and the output of the 3rd comparator chip U3 and V2 port export high level digital signal and be transferred to CPU main controller module; When without plug insertion socket, touch pressing self-resetting switch S1 to turn off, 3rd comparator chip U3 positive input is low level, the output of the 3rd comparator chip U3 and V2 port output low level numeral letter are transferred to CPU main controller module, by the low and high level identification of V2 port, CPU main controller module judges whether plug inserts socket.
9. intelligent electric-shock protection socket system according to claim 3, it is characterized in that, described foil gauge mechanical signal testing circuit comprises the first strain paster Y1, second strain paster Y2, 6th resistance R6, 7th resistance R7, operational amplifier U4, wherein first strain paster Y1 one end is connected with the inverting input of operational amplifier U4, the other end is connected with VCC, second strain paster Y2 one end is connected with the inverting input of operational amplifier U4, other end ground connection GND, 6th resistance R6 one end is connected with the normal phase input end of operational amplifier U4, the other end is connected with VCC, 7th resistance R7 one end is connected with the normal phase input end of operational amplifier U4, other end ground connection GND,
First strain paster Y1 and second strain paster Y2 is attached in Die for Reeds of Connector Jack, when there being plug insertion socket, Die for Reeds of Connector Jack is out of shape, metal foil in first strain paster Y1 and second strain paster Y2 elongates or shortens along with strain, and then resistance value changes, by Wheatstone bridge, the resistance value of change is converted into the magnitude of voltage of change, this voltage amplification is exported to CPU main controller module from the output of operational amplifier U4 and V3 port by operational amplifier U4, CPU main controller module has judged whether plug insertion socket by the voltage value of V3 port.
