Be described further below in conjunction with the control circuit of operation principle above-mentioned Wearable microscope equipment:
Having worn micro-glasses the doctor carries out in the microsurgery process patient; If need adjusting the telescope to one's eyes, the doctor carries out convergent-divergent control; This moment, only using foot was pressed the switch S 1 in the foot switch module 101; Then capacitor C 1 is by short circuit; The second end direct output of DC current (this unidirectional current is as the convergent-divergent triggering signal) of resistance R 1 is to second general purpose I/O pin PA1 of microcontroller U2; Microcontroller U2 exports a high level and triggers 3-axis acceleration sensor U1 work as mode select signal after receiving this unidirectional current, so 3-axis acceleration sensor U1 can export corresponding three-dimensional coordinate signal according to moving up and down from its X axis signal output pin Xout, Y axis signal output pin Yout and Z axis signal output pin Zout of doctor's head; When doctor's head moves down; Microcontroller U2 exports high level and low level (high level and low level are jointly as resizing control signal) respectively to the input pin IN of digital isolator U3 and first end of resistance R 7 according to corresponding three-dimensional coordinate signal from its 7th general purpose I/O pin PC0 and the 8th general purpose I/O pin PC1, and the output pin OUT of digital isolator U3 exports high level triggering NMOS and manages the Q1 conducting subsequently, and NPN type audion Q2 can't obtain bias voltage from resistance R 9 because of base stage and ends; So; Dpdt relay K1 no power, its first switch contact 1 still is communicated with first normally-closed contact 3 and second normally-closed contact 5 respectively with second switch contact 2, then first normally-closed contact, the 3 output+12V unidirectional currents of dpdt relay K1; And second normally-closed contact 5 is managed Q1 ground connection through NMOS, and then makes first motor, 200 forward rotation to increase microscopical amplification; When doctor's head up moves; Microcontroller U2 all exports high level (high level is as resizing control signal) to the input pin IN of digital isolator U3 and first end of resistance R 7 according to corresponding three-dimensional coordinate signal from its 7th general purpose I/O pin PC0 and the 8th general purpose I/O pin PC1; The high level of the output pin OUT of digital isolator U3 output subsequently makes NMOS pipe Q1 conducting; And NPN type audion Q2 obtains the bias voltage conducting because of base stage from resistance R 9; So, dpdt relay K1 energising, its first switch contact 1 is communicated with first normally opened contact 4 and second normally opened contact 6 respectively with second switch contact 2; Because first normally opened contact 4 and second normally opened contact 6 connect second normally-closed contact 5 and first normally-closed contact 3 respectively; Then this moment dpdt relay K1 second normally-closed contact, 5 output+12V unidirectional currents, and first normally-closed contact 3 manages Q1 ground connection through NMOS, and then makes first motor, 200 backward rotation to dwindle microscopical amplification.
After the completion convergent-divergent control that the doctor adjusts the telescope to one's eyes; The control of focusing if the doctor need adjust the telescope to one's eyes; This moment, only using foot was pressed the switch S 2 in the foot switch module 101; Then capacitor C 2 is by short circuit; The second end direct output of DC current of resistance R 2 (this unidirectional current is as the focusing triggering signal) is to first general purpose I/O pin PA0-WKUP of microcontroller U2; Microcontroller U2 exports a low level and triggers 3-axis acceleration sensor U1 work as mode select signal after receiving this unidirectional current, so 3-axis acceleration sensor U1 can export corresponding three-dimensional coordinate signal according to moving up and down from its X axis signal output pin Xout, Y axis signal output pin Yout and Z axis signal output pin Zout of doctor's head; When doctor's head moves down; Microcontroller U2 exports high level and low level (high level and low level are common as the focusing control signal) respectively to the input pin IN of digital isolator U4 and first end of resistance R 13 according to corresponding three-dimensional coordinate signal from its 9th general purpose I/O pin PC2 and the tenth general purpose I/O pin PC3, and the output pin OUT of digital isolator U4 exports high level triggering NMOS and manages the Q3 conducting subsequently, and NPN type audion Q4 can't obtain bias voltage from resistance R 13 because of base stage to be ended; So; Dpdt relay K2 no power, its first switch contact 1 still is communicated with first normally-closed contact 3 and second normally-closed contact 5 respectively with second switch contact 2, then first normally-closed contact, the 3 output+12V unidirectional currents of dpdt relay K2; And second normally-closed contact 5 is managed Q3 ground connection through NMOS, and then makes second motor, 300 forward rotation to extend microscopical focal length; When doctor's head up moves; Microcontroller U2 all exports high level (high level is as resizing control signal) to the input pin IN of digital isolator U4 and first end of resistance R 13 according to corresponding three-dimensional coordinate signal from its 9th general purpose I/O pin PC2 and the tenth general purpose I/O pin PC3; The high level of the output pin OUT of digital isolator U4 output subsequently makes NMOS pipe Q3 conducting; And NPN type audion Q4 obtains the bias voltage conducting because of base stage from resistance R 13; So, dpdt relay K2 energising, its first switch contact 1 is communicated with first normally opened contact 4 and second normally opened contact 6 respectively with second switch contact 2; Because first normally opened contact 4 and second normally opened contact 6 connect second normally-closed contact 5 and first normally-closed contact 3 respectively; Then this moment dpdt relay K2 second normally-closed contact, 5 output+12V unidirectional currents, and first normally-closed contact 3 manages Q3 ground connection through NMOS, and then makes second motor, 300 backward rotation to shorten microscopical focal length.
Another purpose of the embodiment of the invention also is to provide a kind of operating Wearable microscope equipment that is used for, and this Wearable microscope equipment comprises above-mentioned control circuit.
