摘　　要：运用PLC控制技术与组态技术设计了一套摩托车盘式制动器装配生产线的在线检测监控系统。系统通过RS232串口通讯、Modbus TCP/IP通信方式,实现了触摸屏与ATEQ气密检测仪、触摸屏与上位机组态工程之间的数据通信。利用MCGS触摸屏（TPC7062K）实现运行状态监控、检测数据显示,通过上位组态工程完成对生产线的实时监控和数据保存,实现历史数据的查询、显示、Excel报表导出、合格率统计等功能。经过实际测试,系统运行稳定,安全可靠,效果良好。Evidences show that Traditional Chinese Medicines （TCM） plus Nucleoside Analogues （NA） anti-Hepa- titis B Virus （HBV） infection therapy may not only suppress chronic HBV patients＇ serum HBV DNA level but also regulate patients＇ specific immune functions, which clear HBV directly and almost do not damage patients＇ hepato- cytes. This paper introduces a differential equation model with five state variables to describe the dynamics of TCM＋NA anti-HBV infection therapy. It has been proved that if a basic virus reproductive number R0 〈 1, then the infection free solution is globally attractive. This result suggests that if an anti-virus infection therapy makes an HBV infected patient＇ s R0 〈 1, then the patient will eventually recover even if the patient＇ s serum HBV DNA has very high level. As an application, this model is used to simulate the dynamics of TCM＋NA anti-HBV infection per- sonalized combination therapy. Numerical simulations and analysis suggest that the TCM＋NA combination thera- pies are able to activate patients＇ abilities of cytokine-mediated noncytolytic HBV clearance.
