With the development of modern science and technology, electronic computer has been used in temperature monitoring frequently.Therefore, in this paper an information management system of temperature is established for multi-point temperature monitoring system by VB. The design methods and functions of the system is illuminated in detail. The system has not only achieved real-time data communication with temperature monitoring and control circuits but also accomplished the transfer of temperature information and temperature settings. An access database is used to record users’ information and temperature information. Using VB to connect to the database the system has many functions such as the query, display, trend, report generation and so on. The technical targ...
