基于CAN总线的发射机控制系统

文中探讨了基于相控阵雷达发射机CAN总线通讯的发射机控制系统，并介绍了控制系统的各部分组成和功能设计。重点介绍了适用于多终端控制的CAN总线技术的具体运用，单片机、CPLD（复杂可编程逻辑器件）的硬件设计和发射机控制系统软件流程。该控制系统具有硬件简单、维护方便等特点，在实践中运行数年，工作可靠、故障率低。

Transmitter Control System Based on CAN Bus

In this paper we mainly discusse the transmitter control system based on CAN bus communication, and also introduce the construction and design of transmitter control system which are used on a space phased array radar transmitter. Meanwhile we emphasize the detailed instruction of CAN bus communication, the hardware design of single chip microcontroller and CPLD （ Complex Programmable Logic Device） and the software flow chart of transmitter control system. The control system has advantages of simple hardware components and easy maintenance, and it is proved that the system is reliable and stable with few fault.
