摘　　要：为实现无人光电探测装置侦察功能的可扩展性,要求其通信接口应具有一定的开放性,以实现功能、高新技术传感器添加和各种先进算法的移植;针对这一问题,利用CAN总线较强的带负载能力和可接多个通讯节点的特点,提出了一种基于CAN总线的无人光电探测装置控制系统的设计方案;方案中设计了智能CAN通信接口模块,给出了其硬件、软件上的具体设计与实现,其可让连接的传感器快速接入CAN总线工作;验证试验结果表明,该设计通信实时性好,误码率低,能够满足系统对扩展性及控制任务的要求,有良好的实际应用价值。In order to achieve the scalability of unmanned electro--optical detector, which makes high technology sensors and any ad- vanced algorithm addition facilely, it needs its communication interface to be opened. This paper presents a design of the control system for the unmanned electro--optical detector based on CAN to resolve this problem, which using the merits of CAN Bus, the stronger loading ca- pability and many communication nodes coexistence. This system introduces a communication module interface circuit, discussing that hard- ware organization and software on the specific design and implementation, which can make this sensor into network quickly. The test experiment＇s results indicate that the control unit has higher timeliness and lower bit error rate, and can realize the control strategy exactly and fulfill the scalability and control mission of the unmanned electro--optical detector systems.
