基于我國(guó)大型冷庫(kù)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(chǎng)總線的大型冷庫(kù)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(shí)也實(shí)現(xiàn)了整個(gè)冷庫(kù)運(yùn)行過(guò)程的實(shí)時(shí)監(jiān)控和管理。將此設(shè)計(jì)運(yùn)用于實(shí)
際的水產(chǎn)食品冷庫(kù)系統(tǒng)中，取得了令人滿意的控制效果和經(jīng)濟(jì)效益。
關(guān)鍵詞 冷庫(kù)系統(tǒng); 網(wǎng)絡(luò)監(jiān)控; PLC 控制; Profibus
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
