Servo control is the core component of the radar system which has the following characteristics. In harsh environment,the diffi-culty of communication of the servo control system is improved significantly,which makes its design complexity and realization difficulty increased. Thus it is particularly important to design a simple,stable and highly reliable communication interface between radar center and radar servo system. It consists of hardware and software and corresponding communication protocol which relies on controlling and repl-ying messages between radar center and radar servo to achieve and uses special control chip named TMS320F28335 produced by the com-pany TI to act as controllers,which transmits data through serial communication mode. By using C language on the CCS3. 3 platform to write the matching program code,it can realize the logic control and the transmitting of the interface. The design of the communication in-terface plays an important role in improving its stability and reliability,and to some extent can reduce the cost of the production.%伺服控制系统是雷达系统的核心部件,具有随动性,而在恶劣环境下,伺服控制系统的通信难度显著提高,使得其设计复杂度及实现难度也相应增加,因此设计一种简单稳定且可靠性高的雷达主机与雷达伺服的通信接口就显得尤为重要.通信接口主要由相应的软硬件及通信协议组成,其通信协议采用雷达主机与雷达伺服间的控制报文和回复报文来实现,运用TI公司生产的专用控制芯片TMS320F28335充当控制器,通过串行通信方式来实现数据传输.利用C语言在Code Composer Studio(CCS)3.3平台上编写相应的程序代码进而实现了通信接口的逻辑控制与通信.该通信接口的设计对进一步提高伺服控制系统的稳定性、可靠性具有重要作用,同时也在一定程度上降低了生产成本.
