大型冷庫網(wǎng)絡(luò)控制系統(tǒng)設(shè)計

基于我國大型冷庫的制冷監(jiān)控系統(tǒng)主要采用人工或集中式控制的現(xiàn)狀，提出一種基于PLC 和Profibus 現(xiàn)場總線的大型冷庫網(wǎng)絡(luò)控制系統(tǒng)。此控制系統(tǒng)不僅提高了控制品質(zhì)和效率，同時也實現(xiàn)了整個冷庫運(yùn)行過程的實時監(jiān)控和管理。將此設(shè)計運(yùn)用于實
際的水產(chǎn)食品冷庫系統(tǒng)中，取得了令人滿意的控制效果和經(jīng)濟(jì)效益。

Abstract—Based on the state of manual control or concentrating control of large-scale cold storage in our country presently, a kind of network control system for large-scale cold stroage based on the PLC and Profibus is proposed. The solution not only improves the
control quality and efficiency, but also realizes the real time monitor and management of the whole circulating process. It obtains to a satisfied control and economic resulet when it used in an actual aquatic grocery cold storage system.
Keywords—cold storage; network monitoring; PLC control; Profibus
