【正文】 基于PLC的溫度控制系統(tǒng)設(shè)計(jì)摘要 可編程控制器(plc)作為傳統(tǒng)繼電器控制裝置的替代產(chǎn)品已廣泛應(yīng)用工業(yè)控制的各個(gè)領(lǐng)域，由于它可通過(guò)軟件來(lái)改變控制過(guò)程，而且具有體積小，組裝靈活，編程簡(jiǎn)單抗干擾能力強(qiáng)及可靠性高等特點(diǎn)，非常適合于在惡劣的工業(yè)環(huán)境下使用。本文所涉及到的溫度控制系統(tǒng)能夠監(jiān)控現(xiàn)場(chǎng)的溫度，其軟件控制主要是編程語(yǔ)言，對(duì)PLC而言是梯形語(yǔ)言，梯形語(yǔ)言是PLC目前用的最多的編程語(yǔ)言。關(guān)鍵字： PLC 編程語(yǔ)言 溫度Design of the temperature control Systems based on PLC Abstract Programming controler ( plc ) the replacing product as traditional relay control equipment each that already applies industrial control extensively field ，Since it can change control course through software ，It is little to have volume，Assembly is flexible , the programming simple ability of interference rejection is strong and reliability higher characteristic, suit very much in bad industrial environment use. The temperature control system that this paper is concerned with can the temperature of monitoring , its software control is programming language mainly, for PLC is laddershaped language, laddershaped language is the most programming language that PLC now uses.
