摘要
介绍了兰州重离子加速器分时供束系统中Chopper模式解析子系统的体系结构及硬件组成,分析了软件需求,并采用多线程技术设计了Chopper模式解析程序。首先使用NI-DAQmx函数实时读取PXI6133数据采集卡上采集的Chopper模式脉冲,然后对其作进一步分析,最后使用TCP/IP协议将相应的工作模式控制指令发送给控制器。设计的程序达到了系统要求,实现了Chopper模式自动转换的功能,并通过了现场测试。
Abstract
Chopper is an important equipment in beam distribution system based on time of heavy ion research facility in Lanzhou(HIRFL). This paper introduces its mode analysis system’s architecture and hardware composition, analyzes corresponding software requirements, and designs the mode analysis program using multithreading technology. Firstly the program reads mode pulse data of chopper from data acquisition card by NI-DAQmx function, then uses the data for further analysis, and finally sends corresponding work mode control instruction to chopper controller through TCP/IP protocol. The designed program meets system requirements, realizing the function of chopper mode automatic conversion, and has passed the field test.
