摘要
介绍了由PC机和西门子PLC构成的二级温度监控系统,并就系统硬件组成、热电偶模块的数据采集方法、PLC通信与控制程序设计、PC机通信与监控程序设计、中断程序的设计等相关技术进行了分析,给出了部分程序及流程图。
The two-tier temperature supervision and control system which consists of PC and Siemens PLC was introduced.The related techniques about the hardware composition of the system,the method of data collection by the themocouple module,the designing of PLC communication and control program,the designing of interrupt program and so on were analyzed,and the partial program and flow chart were given out.
