With the development of modern science and technology, electronic puter has been used in temperature monitoring frequently. Therefore, in this paper an information management system of temperature is established for multipoint temperature monitoring system by VB. The design methods and functions of the system is illuminated in detail. The system has not only achieved realtime data munication with temperature monitoring and control circuits but also acplished 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 target of the record, the transmission of realtime temperature information and the temperature settings is also achieved. The multipoint temperature monitoring system has good humanputer interface, good mon, simple and convenient operation. It is easy to implement centralized monitorin
