摘　　要：光电跟踪仪数据采集是利用DSP处理技术及多总线结构,实现电视跟踪通道、红外跟踪通道、激光测距机、光纤陀螺仪等多传感器数据的提取,并采用CPCI总线技术结合双端口存储器(双端口RAM)实现系统中信息的快速传输,为光电跟踪仪伺服控制系统提供可靠的数据信息。介绍数据采集系统的设计思想及工作原理,重点研究系统中各传感器的控制方式和接口设计等,并简要说明各系统之间的信息传输方式。The data acquisition in a multi-sensors electro-optical tracker, which includes TV, FLIR, laser rangefinder and fiber gyroscope, was implemented with a digital signal processor and a multi-bus architecture. CPCI bus technique combined with dual port RAM was incorporated to realize high-speed information transmission within the system. It can provide the servo control system with reliable data for fully digitalized control, high-precision sight stabilization, fast and accurate tracking, and improve the performance of the electro-optical tracker effectively. The design scheme and operation principle of the data acquisition system are presented. The control mode and interface design of each sensor in the system are studied. The data transmission between all of the sub-systems is described briefly.
