Embodiment
Embodiment 1: as shown in Figure 1, present embodiment comprises guidance panel 5, and knob assembly that cooperatively interacts and communication part, both are adsorbed in the both sides up and down of guidance panel 5 respectively, and adopt way of electromagnetic induction to come transmission information, comprise the position of knob or/and move or/and the resistance value or/and the state information of switch etc. realize the switch adjusting.
Described knob assembly comprises the shell (adopting ultra-sonic welded or screw to be connected) that loam cake 7 and upper cover base 8 are formed between the two, and the knob 6 that is arranged in this cover top portion; Be provided with first magnet 3 and first wiring board 4 in the described upper cover base 8, wherein be welded with the whirligig 2 (can be potentiometer, code switch or DIP switch) that is used to regulate this wiring board loop resistance value on first wiring board 4, fixedly connected with loam cake 7 by nut in this whirligig middle part, its rotating shaft is connected by interference fit with the endoporus of knob 6, turning knob 6, the rotating shaft that gets final product driven rotary device 2 rotates, thus the resistance of regulating loop on first wiring board 4; Be electrically connected with first inductance coil 9 on described first wiring board 4, this inductance coil can directly be printed on first wiring board 4, but also is fixed on first wiring board 4 behind the coiled coil, even can be fixed in the groove of upper cover base 8.
Described communication part comprises the housing that lower cover base 13 and lower cover 14 are formed, wherein be provided with second magnet 11 and second wiring board 12 in the lower cover 14, second magnet 11 is corresponding with the position of first magnet 3, and both a relative end polarity is different, attract each other, make knob assembly and communication part respectively symmetry be adsorbed in guidance panel about in the of 5 both sides and be operated panel 5 and separate fully; Be electrically connected with second inductance coil 10 that is coupled with first inductance coil 9 on second wiring board 12, this inductance coil can directly be printed on second wiring board 12, but also be fixed in behind the coiled coil on second wiring board 12, even can be fixed in the groove of lower cover 14.
The operation principle of present embodiment is: as Fig. 2-shown in Figure 4, turning knob 6, the rotating shaft that gets final product driven rotary device 2 rotates, the resistance in loop on first wiring board 4 is changed, thereby current in loop is changed, the signal that electric current is changed sends coding circuit 4-3 to simultaneously, described coding circuit 4-3 carries out obtaining a code signal after the encoding process to signal, code signal outputs to the first coil driver 4-4 by the output of coding circuit 4-3, drives first inductance coil 9 code signal is sent.Second inductance coil 10 obtains the signal of first inductance coil 9 by the coil coupling, and this signal is passed to demodulator circuit 12-2 carry out demodulation and output to shaping circuit 12-3, the signal that demodulation is come out returns to can be by the level of computer or microcontroller identification.A high frequency alternating signal (frequency can be selected in 80kHz～5.6GHz scope) is loaded into the second coil driver 12-4, one end simultaneously, drives second inductance coil 10 by the second coil driver 12-4, makes second inductance coil 10 produce alternating magnetic field.Described first inductance coil 9 obtains the needed electric energy of first wiring board, 4 work by the mode of electromagnetic induction, and circuit is simple, and need not to increase extra supplying cell again.First inductance coil 9 resonant capacitance 4-6 in parallel at least wherein, second inductance coil 10 resonant capacitance 12-7 that connects at least, the resonance frequency that can mate two circuit like this makes first wiring board 4 obtain enough work energy.
