Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The main functional modules that the present invention comprises consists of the following components:
Current rectifying and wave filtering circuit carries out rectifying and wave-filtering to the high frequency voltage of receiving coil, and is changed into direct voltage, carries out AD conversion to supply AD circuit.
A/D convertor circuit adopts TLC1549 chip to realize, function be to rectifying and wave-filtering after receiving coil induced voltage carry out AD conversion, and flow to microcontroller and carry out analyzing and processing.
Micro controller module is the nucleus module of this invention.Adopt Atmega16 single-chip microcomputer as the maincenter control section of system, be responsible for the work of control system each several part, the data of AD conversion input are processed and judged, determine that control signal corresponding to the best orientation that receiving coil mates with transmitting coil is as output signal, sends to driver module.
Driver module is the execution part of system, and its Driving Stepping Motor drives receiving coil to rotate, and along with microcontroller sends the continuous renewal of signal, eventually with moving winding rotates to optimum orientation.
As shown in Figure 1, the stepping motor band moving winding of driver module rotates, and the high-frequency voltage signal simultaneously received by receiving coil is direct voltage through current rectifying and wave filtering circuit rectification, and this direct voltage is carried out AD conversion by A/D convertor circuit, be converted to corresponding digital signal, send microcontroller to.Microcontroller is through data acquisition, after analyzing and processing, the control signal corresponding to best orientation that selection receiving coil mates with transmitting coil, as output, controls driver module and drives stepping motor to rotate, transmitting coil is positioned, realizes the optimal orientation with receiving coil.
As shown in Figure 2, diode D1 and electric capacity C1 forms rectification and filter circuit, and LM358 forms voltage follower, plays buffer action.LTC1549 is AD conversion chip.U2 is Atmega16 single-chip microcomputer, binary voltage signal after AD conversion is inputted by PB0, PB1, PB2 pin, the control signal exported outputs to ULN2003 via PA7, PA6, PA5, PA4 tetra-pins, ULN2003 realizes the amplification to control signal, enough power is provided to stepping motor, stepping motor then drives receiving coil to rotate, and realizes seeking to function.
As shown in Figure 3, after program starts, determine the initial direction of rotation of stepping motor, stepping motor often turns and moves a step, and namely to voltage sample repeatedly, is set as 256 times herein, and asks for average voltage, to obtain more accurate and stable magnitude of voltage, and preserve this value.After motor revolves and turns around, stop operating, program searches for maximum in the magnitude of voltage of stored each stepping point, determines the physical location of maximum, calculate the step pitch number between stepping motor current location and optimum position, and according to this step pitch number again Driving Stepping Motor rotate to this position.The accurate location in receiving coil and transmitting coil optimum Match orientation can be realized like this.
