CAN總線在玻璃燒結(jié)爐溫控系統(tǒng)中的應用

針對彩色平板玻璃生產(chǎn)工藝對燒結(jié)爐溫度必須按照升降溫曲線變化和多加熱區(qū)溫度
控制的需求，設計了由CAN 總線、工業(yè)控制機和智能節(jié)點等組成的玻璃燒結(jié)爐溫度控制系統(tǒng)，解決了玻璃燒結(jié)爐多區(qū)溫度精確控制的難題。實際運行效果表明，該系統(tǒng)能精確控制玻璃燒結(jié)爐18 路溫度按照升降溫曲線進行變化，溫差小，完全達到了生產(chǎn)工藝的技術要求。

Abstract Aimed at the colorized glass plate production technology, a temperature control
system for glass sintering furnace is designed, in which the temperature must be changed
according to the given curve and the temperature control is multi-sectional. The system is
composed by CAN bus, industrial computer and intelligent node, which solves the puzzle of
precise control of multi-sectional temperature. In actual application, the system can control
temperature exactly for 18 ways as curve, and the difference in temperature is little, achieving the requirement of production technology completely.
