3, a kind of computer remote monitoring aluminum cell casing method of temperature of utilizing according to claim 2 is characterized in that also comprising measurement point temperature monitoring step g, is undertaken by following step:
G-1.web server (4) is with database data: the temperature of measurement point and Measuring Time merge with the XML data stream format and to be kept at current page, and this page or leaf turned back to the browser of monitoring side computer (3);
G-2. browser is carried out the client script on the page;
G-3. browser reads the data query of downloading with the XML data stream format in this page and is saved in the ADO recordset object of monitoring side;
G-4. with the data assignment in the record set to the PivotTable control object that embeds on the webpage;
G-5. calculate the field that gathers of medial temperature for one of PivotTable Object Creation;
G-6. monthly with different levels time word paragraph format is set is " during yyyy/q season/mmm month/dd day/hh/the mm branch ";
G-7. with PivotTable object assignment to the Chart control object on the webpage;
G-8. set the classification axle and be field of stratified time monthly, number line is that medial temperature gathers field, creates measuring point temperature curve over time.
