The design methods and functions of the system is illuminated in detail . The system has not only achieved real-time data communication with SCM but also maked the collect real-time data process . It introduces the SCM and PC setial communication method,and gives a specific flow chart of communication interface circuit and SCM serial communication program . It gives an account of data display and the trend of the realization of methods, and introduces how to use VB6.0 to connect to the database , the system has many functions such as the query , display , trend , print and so on. In serial communication , a machine using SCM serial port for data transmission , and PC is using VB to realize the communication between host computer (computer) and lower computer (MCU) is realized by using the MSComm control in VB . And the real-time data acquisition and dynamic graphics display from host computer to lower computer are completed through the coordination of Picture control and Timer control . The dynamic graphics display of data provides a dynamic and visual impression to the data analysis, and becomes an important link for data analysis. The system has been designed with Access database , it is recorded user information and temperature information . The technical target of the record, the transmission of real-time temperature information and the temperature settings is also achieved. The temperature management system of constant temperature water tank has good human-computer interface , good common, simple and convenient operation . It is easy to implement centralized monitoring and management of the
