Abstract :
The development trend of focusing control system is high speed, reliable control and miniaturization. A new auto-focusing control system based on CAN bus is designed, which realizes the real-time communication and synchronization control among the distributed control system. A design process of CAN interface based on TJA1050 is presented. The principle of focusing control and the hardware and software design are presented in detail. All experiments show that the control system has the advantages such as high accuracy and anti-interference ability, and meets the requirements of high speed and good stability.
