摘要
为满足兰州重离子加速器冷却储存环(HIRFL-CSR)浅层和深层重离子治癌装置中对病人病灶位置信息的监测与远程控制的需求,基于FPGA技术构建嵌入式实时控制系统,以PCI总线为通信接口,选用凌华的PXI 3800工业控制计算机为上位机,并采用逐点比较运动控制算法来实现定位控制,开发了相应的软件和可视化的监控界面,完成了加速器束运系统和治疗装置的集成。经现场测试,本系统运行稳定可靠,达到了设计要求。
In order to fulfill the requirement of monitoring and long distance control of patients lesion location information during the shallow and deep radiotherapy with heavy ion on the Heavy Ion Research Facility in Lanzhou-Cooler Storage Ring（HIRFL-CSR）,the corresponding software and visual monitoring interface were developed,the integration of ion beam transport system and therapy equipment were completed.The embedded real-time control system was constructed by FPGA technology.The PCI bus and ADLINK’s industrial control computer of PXI 3800 were used as communication interface and host computer respectively.The algorithm of the point by point comparison motion control was selected to achieve the position control.Through the test on the spot,the system is robust and reliable,and satisfies the design requirement.
