It surveys device to be initialized, piezoelectric transducer reads the information of piezoelectric inductor, carries out the place of signal filtering, amplification, A/D conversion
Reason, then sends the information after the completion of processing to microprocessor, and after microprocessor is handled, final relative gravity is believed
Breath is shown by man-machine interface.
9. the method surveyed as claimed in claim 8 using the full-automatic relative gravity acceleration surveying device of electronic type,
It is characterized in that, described is initialized as: microprocessor is by power drives X-axis piezo-electric motor first, and receives X-axis piezoelectricity horse
The Voltage Feedback reached, control X-axis piezo-electric motor carry out telescopic oscillating, push interior vacuum chamber, while microcomputer reads voltage inductance
It answers the data of device and is judged, in X-axis piezo-electric motor motion process, if the numerical value of piezoelectric inductor is greater than preceding value,
Microprocessor control X-axis piezo-electric motor continues equidirectional movement, if the numerical value of piezoelectric inductor is less than preceding value, micro- place
It manages device and controls X-axis piezo-electric motor to opposite direction movement, be finally stable at the maximum of points that piezoelectric inductor is surveyed, reach and the point
The identical face in acceleration of gravity direction；Then Y-axis piezo-electric motor repeats the process of the above X-axis piezo-electric motor, obtain and piezoelectricity
The identical two faces intersection in the acceleration of gravity direction for the maximum of points that inductor is surveyed obtains the acceleration of gravity side of the point
To, finally make connecting rod consistent with acceleration of gravity direction, complete initialization.
10. the method surveyed as claimed in claim 9 using the full-automatic relative gravity acceleration surveying device of electronic type,
It is characterized in that, X-axis piezo-electric motor and Y-axis piezo-electric motor are locked after the completion of the initialization.
