The encoder is used for position detection of electro-optical tracking system
Absolute photoelectric axis encoder is the photoelectric tracking system in the photoelectric tracking with the frame to measure the azimuth angle and pitch angle sensor, the photoelectric tracking system internal bus structure for the CAN bus communication mode, the encoder CAN bus interface to play its interface flexibility, Save the characteristics of the line, and it itself with a microprocessor, can be used as an intelligent node in the system, directly to other devices to send remote frames, to achieve intelligent control. Figure 2 is based on the CAN bus-based optical tracking system communication structure. The photoelectric tracking system uses the CAN bus single serial bus structure to replace the parallel structure of many communication modes. The azimuth and elevation angle measured by the two photoelectric encoders are sent to the main controller through the bus, and the main controller will deal with the data accordingly. , Through the bus control servo control system, all subsystems can be connected through a pair of twisted-pair, simplifying system wiring, improve the overall system bus utilization, real-time data transmission and system scalability, while the bit error rate greatly reduce
