摘要
目前我国PVC塑料加工行业中，对PVC原料的输送，计量，配混，储
存大多数仍由人工来操作，采用常规仪表来监控各种温度、时间参数。在
这种生产方式下，计量精度低，工艺循环周期长，生产效率低，同化学分
子的直接接触严重威害着一线工人的健康，生产过程中泄露产生的化学粉
尘又严重污染了环境。
基于这样的背景，本论文对PVC塑料生产的整个工序提出计算机监控
技术，研制出IPC-PLC DCS系统，运用一定的给料算法，实现系统动态称
量中落差的自动补偿与粗流给料设定值的自动修正，提高了PVC连续生产
中动态称量的精度与速度，并将整个生产工艺规划于密闭管路和各种料仓
中进行，实现作业无尘化、环境优化、生产自动化与管理科学化，适应当
前现代化生产的需求，为PVC塑料工业的发展作出新的探索与创新。
At present in the industry of PVC the process in convegance, measurement , compounding and storage of PVC raw material are realized by hand and monitoring to various parameters, such as time, temperature, is completed by common meters. In this production mode, the old system results into vague precision, long process cycle and low efficiency. Furthermore, the direct contact with chemical raw material does great harm to workers' health and dust dispersed into air pollutes circumstance.
Based on such background this system brings forward microcomputer
monitoring and controlling technique to PVC process in production,
researches IPC-PLC distributed control system,applies new
algorithm of measurement,realizes automatic compensation of
dropping of material and automatic amendment of high-speed
measurement in the dynamic measurement, improves dynamic measurement
precision and speed in PVC continual production. At the same time,
this system accomplishes the whole process in airtight pipelines
and storehouses, realizes dustless production, clean producing
condition, automation, scientific management, meets the demand of modern production,
makes some new exploration and creation in production of PVC industry.
