摘 要 三聚氯氰是一种重要的精细化工产品，具有广泛的用途，它是农药工业的中间体，是制造活性染料的原料，可做有机工业生产的各种助剂，如荧光增白剂、纺织物防缩水剂、表面活性剂等，是橡胶促进剂和国防用于制造炸药的原料之一，也是医药农药工业用于合成药物的原料。三聚氯氰三聚氯氰三聚氯氰Abstract CNCL is a kind of important and fine chemical engineering product, have extensive use, it is the middle body of agrochemical industry, is the raw material which makes live dyestuff, can do organic industry and produce of various help, if the fluorescence increases a white, spin and weave a thing and defend a shrinkage, surface a live etc. is one of the raw material that rubber accelerant and national defense used for making explosive, is also medicine agrochemical industry used for synthesizing medicine of raw material. CNCLs use to are of a great variety, but its production is very and complicated, again because of his chemistry property unsteady, the liquid appearance leaks easily, in the production line again produce much poisonous air, so is basically unsuitable for people to participate production in person. Build up CNCL to produce a PLC control system is very have to.the control system of the CNCL production PLC to make to produce automation, can make operation personnel Be transacting indoor see the dynamic state appearance of production process, thus better control and regulate production. This item design of control system adoption WinCC person machine the appearance is a place of honor machine, there aring supervision and data to collect (SCADA) function, and having a set of form , development and opening function. Can carry out to establish appearance, pass the button in the appearance to carry out to rise system, stop, break down a processing etc. a control, carry out a long range control thus; Change quantity set form , industry the spot of produce condition will solid hour ground reflection at set form appearance up, thus better regulate production; The process value returns back to file, the trend curve and the form is been returned back to file by manifestation of history data; The statement prints,
