Operation principle of the present invention is following: the Vcc input 24V of Automatic Detection and Control unit; After powering up; The first dual operational amplifier U4 and second dual operational amplifier U5 work; Through drain electrode and the transmitting coil L2 power supply of the 25 resistance R 25 to FET Q5, this moment, FET Q5 and transmitting coil L2 were in holding state; 24V voltage is exported the 12V burning voltage after three terminal regulator U1 step-down, voltage stabilizing, to first o'clock base chip U2 power supply, and first o'clock base chip U2 output pulse signal; Regulating the first potentiometer VR1 and the second potentiometer VR2, to make the pulse period be 10S, and duty ratio is 1/10, and promptly high level is 1S; Low level is the pulse signal of 9S; Be used to control the power control switch of forming by the first triode Q1 and the second triode Q2, when pulse high level, the first triode Q1 conducting; To base chip U3, the 3rd triode Q3, the 4th triode Q4 and FET Q5 power supply in second o'clock; When non-loaded, the 19 R19, the 21 resistance R the 21, the 22 resistance R 22 and the 23 resistance R 23 are set make electric current in 200mA, regulate frequency of oscillation that the 3rd potentiometer VR3 makes second o'clock base chip U3 at 255KHZ; The second operational amplifier U5 and the 26 to 30 resistance R 26-R30 form amplifying circuit; Amplification is from the voltage at the 25 resistance R 25 two ends; And the first operational amplifier U4 and the 13 to the 15 resistance R 13-R15 and the 7th diode D7; The 9th resistance R 9 and the 16 resistance R 16 are formed comparison circuit, the voltage after relatively amplifying from amplifying circuit; When receiving coil L3 away from transmitting coil L2 not in the electromagnetic radiation scope time; Be that system is unloaded; System power is less, flows through pressure drop that the electric current of the 25 resistance R 25 the produces comparison circuit that after second operational amplifier U5 amplification, is not enough to overturn, and can't drive the LED of indicating member; Then the first triode Q1 closes behind the 1S, and system comes back to holding state.
When in the electromagnetic radiation scope of receiving coil L3 at transmitting coil L2; And parallel being placed in the 2mm of transmitting coil coil L2 top of receiving coil L3 located; And it is in when concentric; System is in the load holding state, controls for first triode Q1 conducting moment from first o'clock base chip U2 output pulse signal, flows through pressure drop that the electric current of the 25 resistance R 25 the produces comparison circuit that after the second operational amplifier U5 amplifies, overturns; The high level of output is controlled the first triode Q1 through the 4th diode D4, the 8th resistance R 8, the 7th resistance R 7 and the 6th diode D6 and is in and keeps conducting state, and is at this moment inoperative from the pulse signal of first o'clock basic chip U2; Because the junction of the 6th resistance R 6 and the 6th diode D6 is a high level before the first operational amplifier U4 of comparison circuit upset always; This state does not change with the pulse condition from first o'clock base chip U2 through the 5th diode D5. and the high level of first operational amplifier U4 output gives the 7th capacitor C 7 chargings simultaneously; Adjust the value of the 7th capacitor C 7 and the 7th resistance R 7; After making the first operational amplifier U4 output low level; The first triode Q1 can keep conducting state, and for example: 3 minutes (also can be At All Other Times) when guaranteeing that receiving coil L3 and interim short time of transmitting coil L2 move, system still keeps work; Simultaneously; System is when work; The second operational amplifier U5 amplifies the LED lamp of the voltage of output through the 6th triode Q6 driving indicating member; The number that the LED lamp is lighted reflects that the second operational amplifier U5 amplifies the height of output voltage, whether is placed in the optimum position according to the unlatching number reflection receiving coil L3 of LED lamp; Can change comparator reference voltage through adjusting the 13 resistance R 13 and the 15 resistance R 15, get into operating state when the much power in order to control system.
It is that the electromagnetic wave of 50K-500KHZ is made energy and transmitted that the present invention adopts frequency range, and this is that winding volume is little because components and parts are cheap in this frequency range, and Q value can suitably reduce, and is easy to during production mate; The present invention can guarantee to supply to receive electric coil apart from the 10mm; Efficiency of transmission is higher than 50% during power 50W, in the time of in the 2mm even surpass 80%. in addition, owing to adopt small coil; Electromagnetic radiation in this frequency range is very faint, is easy to satisfy the electromagnetic radiation standard of various countries.
