Embodiment
As shown in Figure 1, comprise launching code integrated circuit, wireless transmit integrated circuit, testing circuit in high pressure detection and the emitter, when testing circuit detects high-voltage charged body, be transmitted into address code by launching code integrated circuit, wireless transmit integrated circuit and be set to consistent wireless receiving and control warning device.
As shown in Figure 2, wireless receiving and control warning device comprise received code integrated circuit, wireless receiving integrated circuit, warning circuit, braking circuit, and described warning circuit, braking circuit are connected with described received code integrated circuit, wireless receiving integrated circuit by controllable silicon.
As shown in Figure 3, before high pressure detection and wireless launcher use, should be according to the electric pressure of institute perform region, regulation voltage is set potentiometer RP1 to the relevant voltage grade, can send alarm signal outward at safe distance to guarantee device.Set all wireless transmit and wireless receiving is encoded to same one-address code by K1, K2.When testing circuit did not detect high-voltage charged body, drain D and the resistance between the source S of field effect transistor Q1 were less, and triode Q2 ends, and radiating circuit does not start.When the close high-voltage charged body of testing circuit, the metal sensing chip that links to each other with the Q1 grid G receives faint electric field signal, it is big that the drain D of field effect transistor Q1 and the resistance between the source S become, triode Q2 conducting, its emitter output high level starts launching code IC circuit 1 (PT2262), and 17 pin of the coding output terminal of IC circuit 1 become high level, start radio transmitter IC2 (F05V), send wireless signal.
As shown in Figure 4, when wireless launcher sends wireless signal, wireless receiving and control warning device receive through IC3 (J05V), and IC4 (PT2272) decoding is at the 13 pin output high level of IC4, trigger controllable silicon TH1 conducting, start braking, warning circuit: relay J 1 excitation, it opens " suddenly stopping " button two ends that contact (J1-1) is connected to the high-altitude operation vehicle electric control loop, carries out brake hard, stop the continuation campaign of construction operation car, prevent unexpected generation; LED 1 glittering alarm simultaneously; Start time base circuit IC5 (NE555) simultaneously, the square-wave signal at its 3 pin output T=4S triggers sound circuit IC6 (HL169), after triode Q3 amplifies, drives the alerting tone that loudspeaker SP sends " electricity is arranged, and Danger! Keep Away "; High-decibel alarm HD sends alarm sound simultaneously, informs workmen on every side.Press reset key SB1, the braking warning circuit resets.
