The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, the utility model is made of emitter and receiving actuating equipment two parts.The frequency oscillator signal 1 of emitter produces frequency of oscillation and sends in the higher-order of oscillation transmitter 2, is sent the signal of certain frequency by transmitter 2.After the reception amplifier 3 of receiving actuating equipment is received the high-frequency oscillation signal that transmitter 2 sends, it is carried out filtering amplifies, send into frequency selection circuit 4 then and carry out the frequency-selecting processing, again through delay circuit 5 time-delays, send into control circuit 6, send alarm signal by control circuit 6 control warning circuits 7, or make circuit for producing high voltage 9 output high-voltage electric shocks through delay circuit 8.
Referring to Fig. 2, the frequency oscillator signal 1 of emitter is made of oscillator F1～F5, capacitor C 1～C3, diode D1 and potentiometer W1, regulator potentiometer W1 can make frequency of oscillation change, and this frequency of oscillation is consistent with the frequency-selecting frequency of the frequency selection circuit 4 of receiving actuating equipment.Oscillator signal by oscillator F5 output removes to modulate the higher-order of oscillation transmitter 2 that is made of triode BG1, inductance L 1～L3, capacitor C 4～C8 through capacitor C 4, resistance R 1.Regulate inductance L 2～L3 and variable capacitance CT, can change carrier frequency, this frequency should be consistent with the frequency of receiving actuating equipment.Can check the under-voltage of power supply by switch AN1 and indicator lamp LED1, WD1 is under-voltage voltage-stabiliser tube, and K1 is a power switch.
Referring to Fig. 3, the reception amplifier 3 of receiving actuating equipment amplifies two parts by superregenrative reception and filtering and constitutes.Triode BG2, resistance R 2, potentiometer W2, capacitor C 9～C12, inductance L 4 and GZL constitute Armstrong circuit, resistance R 2 and potentiometer W2 provide the offset operation point for triode BG2, and the frequency that the magnetic core of adjustment inductance L 4 sends its receive frequency and emitter is consistent.Adjusting potentiometer W2 can make triode BG2 be in optimum Working.Operational amplifier IC1, capacitor C 13～C15, resistance R 3 constitute the filtering signal amplifying circuit, are used for the signal after the Armstrong circuit detection is amplified.Frequency selection circuit 4 is made of operational amplifier IC2, and C16 is a coupling capacitance, regulates W3 and can make the frequency-selecting signal of frequency-selecting frequency and emitter consistent.Deliver to the delay circuit 5 that constitutes by capacitor C 18～C19, diode D2 and resistance R 4 through the sine wave signal after the frequency-selecting processing, delay time about 3～4 seconds, remove to control the control circuit 6 that constitutes by triode BG3～BG4, relay J 1 again.Capacitor C 17 is a coupling capacitance.Warning circuit 7 is made of voltage-stabiliser tube WD2, integrated IC3 of sound equipment, triode BG5～BG6, operational amplifier IC4 and high pitch loudspeaker DY.Delay circuit 8 and circuit for producing high voltage 9 are made of resistance R 5～R9, capacitor C 20～C22, triode BG7～BG9 and high pressure generator HB, and capacitor C 23 is a no-spark electric capacity.LED2 is a power supply indicator, and K2, K3 are the power switch of receiving actuating equipment.During use, the Armstrong circuit that is received reception amplifier 3 in the actuating unit by the next modulation signal of emitter emission receives, after amplifying, detection delivers to frequency selection circuit 4, if the signal frequency that receives is identical with this frequency-selecting product rate, then 7 pin of operational amplifier IC2 output high level makes triode BG3 saturation conduction via capacitor C 17, diode D2 and resistance R 4, and BG4 ends, relay J 1 is not worked, and then warning circuit 7 is not worked.At this moment, because positive voltage makes triode BG7 saturation conduction by resistance R 6～R7, BG8～BG9 ends, and then high-tension circuit is not worked, no high pressure output.If emitter and receiving actuating equipment are at a distance of surpassing certain distance, as away from 5 meters the time, reception amplifier 3 will not receive the signal of transmitter 2 emissions, the 8 pin output low levels of the amplifier IC2 in the receiving actuating equipment, at this moment, power supply is to capacitor C 18 chargings, and electric current is through resistance R 4 and triode BG3 discharge, along with the increase in charging interval, capacitor C 18 both end voltage are raise, this needed for 3～4 seconds approximately, and the electric charge on the capacitor C 19 bleeds off, and then triode BG3 ends, the BG4 saturation conduction, relay J 1 work, its contact J1-1 connects the power supply of warning circuit 7, then sends alarm sound, at this moment, the normally-closed contact of contact J1-1 has disconnected the resistance of resistance R 6, and to capacitor C 22 chargings, original electric current is by resistance R 7, R5 and triode BG7 discharge, raise up to capacitor C 22 both end voltage, this needed for 5 seconds approximately, and triode BG7 ends, the BG8 saturation conduction, the also very fast conducting of BG9, then high pressure generator HB two ends add the voltage of about 6V, make it produce high tension voltage, by 3,4 pin export casing and handle to.
