【摘要】 在国家建材行政主管部门提出的“控制总量、调整结构、淘汰落后”的水泥发展方针的指引下,新型干法水泥生产获得了迅猛发展。本文围绕兰丰水泥生产线,介绍了该生产线的DCS系统的选型、方案设计、控制策略组态、上下位组态的集成和系统调试过程。 水泥生产过程是一个包含开关量控制和模拟量调节的混合控制过程,本文在介绍与对比我国水泥生产现状和水泥控制的几种常用手段的基础上,选择了性价比高、专为混合控制过程而设计的PlantScape SCADA/HC900系统来控制兰丰水泥生产线的生产。论文提出了兰丰水泥生产线的控制方案,详细介绍了系统的硬件组成和软件结构。 论文重点介绍了如何通过系统提供的控制策略组态软件HC Designer,实现水泥生产中的数据采集处理和输出、关键参数的PID调节,并为弥补系统提供的顺控模块少的缺陷,介绍了一种利用常规功能模块实现组设备的开停车自动化的方法。 最后,介绍了上位机组态和下位机组态的集成,并完成了系统的综合调试。更多还原

【Abstract】 In the guidance of the National Building Material Administrative Department’s policy of "Control total amount, Adjust structure and Eliminate lag", the new type dry-process cement production has developed rapidly. This paper aimed at LanFeng cement production line, introduced the selection of type, project design, control strategy configuration, the integration of the upper computer configuration and the lower computer configuration, production adjustment about its DCS.The process of cement production includes the digital control and the analog control, on the basis of introduction of the present situation of cement production in our country and comparison of several popular control methods in cement production, we adopt PlantScape SCADA/HC900 designed specially for hybrid control process and with high performance/cost ratio, to control LanFeng cement production line. The paper brought forward the project design of this cement production line, and stressed the hardware composing and the software structure.This paper emphasized how to realize the data acquisition & process and output, the start-stop control of one group of devices and the PID control of some key parameters by using the control strategy configuration software of HC Designer. In order to solve the problem of the lack of sequence blocks system provided, we took general function blocks to achive the automation of the start-stop control in one group of devices.Finally, this paper introduced the integration of upper computer configuration and the lower computer configuration, and introduced the process of production adjustment.更多还原
