Abstract

The invention relates to a voltage-controlled active crystal oscillator control device, a voltage-controlled active crystal oscillator control method and a stage moving head lamp. The voltage-controlled active crystal oscillator control device comprises a controller and a voltage adjusting circuit. The controller is used for receiving a user instruction and generating a voltage regulation parameter according to the user instruction, and the user instruction is input by a user based on frequency offset between the output frequency of the voltage-controlled active crystal oscillator and the nominal frequency of the voltage-controlled active crystal oscillator; the voltage adjusting circuit is electrically connected with the controller, and used for receiving the voltage regulation parameter,regulating a driving voltage according to the voltage regulation parameter and providing the regulated driving voltage for the voltage-controlled active crystal oscillator, so that the frequency offset of the output frequency and the nominal frequency is within a preset range, and the problem of desynchrony caused by different output frequencies of the crystal oscillator is solved.

Description

technical field [0001] The invention relates to the technical field of crystal oscillator control, in particular to a voltage-controlled active crystal oscillator control device and method, and a stage moving head lamp. Background technique [0002] In the field of stage moving head lights, some infinite rotation functions are needed. However, in practical applications, if the moving head lights perform the infinite rotation function for a long time, the rotation angles of multiple stage moving head lights (including X-axis and Y-axis) will be different, that is, the rotation synchronization of multiple moving head lights will be different. good question. One of the main reasons for this problem is due to the frequency deviation of the working crystal oscillator of the crystal oscillator motherboard of each moving head light. During long-term operation, the error is continuously accumulated to cause asynchronous phenomena. Since the crystal oscillator is a standard device ...
