工业控制或民用控制中有一些数据,如浓度、位移、流量、综合成本、综合能耗等,需频繁手工查表并计算。针对这些有数据模型无数学模型的数据转换,无法直接运算,利用本文介绍的PLC程序可以利用已往的计算数据或专家规则,自动转换成所需的结果。基于此功能可以减轻人员工作强度,提高计算精度,减少人为差错,并且可以使用这些数据参与智能控制。所提出的系统成功应用于某公司生产过程一年多,对优化生产管理、降低事故风险,取得了明显的应用成效。
There are some data in industrial control or civil control, such as concentration, displacement, flow rate, comprehensive cost, comprehensive energy consumption and so on. For these data models without mathematical models of data conversion, can not be directly calculated, using the PLC program described in this article can be used to calculate the data or expert rules, automatically converted to the desired results. Based on this function can reduce the staff’s work intensity, improve the calculation accuracy, reduce human error, and can use these data to participate in intelligent control. The proposed system has been successfully applied to a company’s production process more than a year, to optimize production management, reduce accident risk and achieved significant results.
