Aiming at the water temperature measuring problem for controlled cooling system of rolling plant, a new water temperature measuring method based on soft-sensing method with a water temperature model of on-line self correction parameter was built. A water temperature compensation factor model was also built to improve coiling temperature control precision. It was proved that the model meets production requirements. The soft-sensing technique has extensive applications in the field of metal forming.
A wireless search system was integrated on Windows 2000 server. Based on the communication principle between wireless data and Internet, the object expression of search file, the automatic query of document information, the segment browsing of result information, and the receiving and sending of user information were realized by using Active Server Page 3.0, VB Script, WML Script insert languages and object orient database technology. The requirement querying information of material processing through Internet by GPRS, WAP mobile handset and so on was accomplished.
