摘要
针对医用加速器治疗头的功能需求及稳定、精确和实时的控制要求,提出了上、下位机联合控制策略,阐述了控制系统的软硬件结构和工程实现方案。治疗头运动采用直流电机闭环控制,中控台与治疗头通过RS-485总线进行实时通信,中控台监控软件选用Visual C++6.0编写实现。该控制系统已应用于某型号医用加速器,运行结果表明:其功能和性能均能满足放射治疗的要求。
To meet the function requirements and control requirements of stability, precision, and real-time performance of medical accelerator collimator, the host-computer and slave-computer combination control solution was proposed. The structures of software and hardware and the engineering scheme were introduced. DC motor close-loop control was used to control the motion of collimator. RS-485 bus was used to achieve the real-time communication between console and collimator. The supervisory control software was developed on Visual C ＋ ＋ 6. 0. This control system has been applied to a medical accelerator and the results show that it is reliable.
