一种多功能定时控制模块的设计与实现

根据搜索雷达定时、通讯和多功能控制的任务需求，以FPGA 为主要控制器件，构建了基于CPCI 总线架构的多功能定时控制模块。硬件设计包含电源模块、时钟管理、FPGA、PCIe控制和RS-422 串口等功能模块，软件方面使用Verilog 语言编程实现了雷达时序控制、PCIe 接口控制和同步串口数据传输、雷达参数初始化、显控指令分发、分系统状态回告、遮蔽角响应、GPS校时等多种功能。模块随雷达样机在烟台某试验场进行了试验验证，经过整机联调和整机试验，定时控制模块的功能和可靠性得到了充分验证。实际工程应用表明，通用定时接口各模块的功能和性能均能满足系统的设计要求。

Design and Realization of Multi-Function Timing Control Modul

According to the task requirements of timing, communication and multi-function control of a certain type of searchradar, a multi-function timing control module based on CPCI bus architecture is constructed with FPGA as the main control device.The hardware design includes power module, clock management, FPGA, PCIe control, RS-422 serial port and other functionalmodules. The software uses Verilog language programming to realize the radar timing control, PCIe interface and synchronous serialport data transmission, radar parameter initialization, display and control command distribution, sub-system status reporting, shelterAngle setting, GPS timing calibration and so on Kind of function. The module was tested and verified with the radar prototype in atest site in Yantai, and the function and reliability of the timing control module were fully verified through the integrated adjustmentand the whole machine test. The practical engineering application shows that the function and performance of each module of theuniversal timing interface can meet the design requirements of the system.
