Abstract :
The control system of full automated intelligent gyroscope is presented, in which the automatic cursor signal acquisition module is designed based on CCD sensor and digital signal process technique to get the accurate center of the moving cursor in the gyro. Using the novel light source LED instead of lamp, the CCD driver circuit is designed with CPLD. It has been proved through experiments that the module can substitute for manual measurement to recognize the cursor signal effectively. The precision of the gyroscope is improved from 20" to 8".
