Embodiment

As shown in Figure 1, the Circuits System of a kind of intelligent and safe cap of the present utility model, comprise magnetic field induction circuit and single chip machine controlling circuit, described antenna magnetic field sensor circuit is connected the gate pole of field effect transistor Q1 by the output terminal of induction electrode Q, the base stage that the drain electrode output terminal of field effect transistor Q1 connects resistance R 1 and transistor VT1 constitutes, be connected to the 34th pin of 89S52 single-chip microcomputer IC1 by the collector output of transistor VT1, as induction electrode Q during away from the high pressure object, the leakage of field effect transistor Q1, resistance between the source electrode is less, corresponding crystal pipe VT1 is because of the lower cut-off state that is in of its base potential, the 34th pin of single-chip microcomputer IC1 also is low level state, does not have control signal output.As induction electrode Q during near the high pressure object, field effect transistor Q1 end has the induction electric field signal, this moment, leakage, the resistance between the source electrode of Q1 field effect transistor became big, transistor VT1 pipe improves conducting because of its base potential, and the 34th pin of single-chip microcomputer IC1 is high level state, controls three tunnel outputs of appraising by single-chip microcomputer IC1 internal processes, the first via is by the 28th pin output high level of single-chip microcomputer IC1, through resistance 1R2 current limliting, make triode VT2 conducting, news Chinese percussion instrument BD gets electric sending and " ticks.。。" alarm sound, illustrating has herein that Keep Clear-High Voltage, reminds operating personnel to take care, and adjusts the resistance of resistance R 1, can change the measurement safe distance.The 26th pin output high level of secondary route single-chip microcomputer IC1, through resistance 1R3 current limliting, make triode VT3 conducting, be input to the 2nd pin of FDD-5 transmitter module IC3, and deliver to the 3rd pin of FDD-5 transmitter module IC3 modulation signal input end CP, the high-frequency signal of emission is modulated.The TX antenna is to the modulated frequency electromagnetic waves of the outer emission of JDD-5 receiver module IC4, form the radio alarming reception control circuit by JDD-5 receiver module IC4, loudspeaker Y, resistance 1R5 etc., the 4th pin audio signal output end CPA of JDD-5 receiver module IC4 directly drives common electrical dynamic formula loudspeaker Y sounding, its the 2nd pin data output end output high level makes LED 1 get electroluminescence simultaneously, and expression receives the alerting signal of extension set.Reach long-range reception alarm monitoring purpose; Third Road output is by the 8th pin output low level of single-chip microcomputer IC1, and driven for emitting lights diode (LED) 2 is lighted, and this lamp is installed in the safety helmet front end; effect as the prompting warning; reach sound and light alarm and remote alarms, the function of multiple protective is avoided bringing personnel casualty accidents because of touching power fail.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
