目的:基于上海市质子重离子医院质子重离子加速器设备(IONTRIS系统),设计在线纯水分析系统,通过运行数据统计,评估该系统的应用效果.方法:应用西门子S7-300 PLC控制系统,从纯水系统内的传感器中采集在线数据;分析设备运行规律,设置报警限值;使用WINCC软件开发上位机监控及分析系统,实时处理在线数据;通过系统应用前后单月耗材应用成本比较,评估该系统的应用效果.结果:应用在线纯水分析系统后,实现了纯水系统状态的实时监控,耗材的使用效率得到提高.结论:在线纯水分析系统的应用对于提高运行效率有较好的作用.%Objective: To design an online pure water analysis system based on the proton and heavy ion accelerator (IONTRIS system) in Shanghai proton and heavy ion center (SPHIC), and to evaluate its application effect by operating data statistics. Methods: The system used the control system of Siemens S7-300 PLC to collect online data from sensors of pure water system. Analyzing the operation rules and setting the limiting value of alarm, and using WINCC software to develop monitoring and analysis system of central computer so as to real-time operate online data. The application effect of the system was evaluated by comparing the cost of one month consumables between before and after the system was applied. Results: After the system was applied, the real-time monitoring of pure water system was realized, and the efficiency of the consumables was enhanced. Conclusion: The application of the pure water analysis system has a good effect on the operation efficiency of the pure water system.
