 摘       要
 近年来，随着国家对环境保护的要求越来越高，空气污染治理日益成为我国污染防治的一个重要领域。脉冲袋式除尘系统广泛应用于建材、水泥、冶金、铸造、化工、机械、矿山、有色冶金和烟草等各行业，在非腐蚀性、非粘性、非纤维性粉尘的含尘气体的除尘净化或有用物料的回收方面发挥着非常重要的作用。脉冲袋式除尘系统的可靠性及自动化程度直接影响到除尘系统的清灰效果和操作工人的劳动强度，作为除尘系统控制部分之一的脉冲喷吹控制仪，其性能的优劣和使用的方便性、可靠性显得尤为重要。
 为了实现人性化、操作灵活、功能完善，采用单机测控系统考虑对整个除尘器系统建立规则库和推理机实现在线和离线诊断功能,并对故障提供安全可靠的解决方案,使整个系统变得更完善,使操作人员能更安全、更方便地操作整个除尘系统。本系统分上位机和下位机，上位机通过WinCC编程软件实现控制系统，下位机为可编程序控制器。
 毕业设计过程中主要完成的工作：系统总体控制方案的设计，计算机端控制软件与控制器软件的设计及其调试。

Abstract
 In recent years, as the country has more and more high expectations for environmental protection, air pollution control becomes an important field of prevention and control of pollution of our country day by day. The dust removal system of one bag of types of the pulse is applied to such every profession and trade as building materials, cement, metallurgy, casting, chemical industry, machinery, mine, coloured metallurgy and tobacco,etc. In corrosivity, viscidity, fibre containing dust and gas dust removal of dust purify or useful recovery of supplies play a very important role. Dependability of the dust removal system of one bag of types of the pulse and automatic degree influence the clear gray result of the dust removal system and labour intensity of operating workers directly, controlling the pulse, one of some and gushing out and blowing the controller as the dust removal system, the quality, convenience of use, dependability of its performance seem particularly important.
    In order to realize the human nature nimbly, the operation, the function perfect, uses the single plane observation and control system consideration to the entire dust remover system establishment rule storehouse and the inference machine realization on-line and the off-line diagnosis function, and provides the safe reliable solution to the breakdown, causes the overall system to change perfectly, enables the operator to be safer, conveniently operates the entire dust removal system. This system divides on the position machine and the lower position machine, on position machine through WinCC programming software realization control system, lower position machine for programmable foreword controller.
 In the graduation project process mainly completes work: System overall control plan design, computer end control software and controller software design and debugging.
