【摘要】：本文针对目前油库发油系统自动化的需求,在分析国内外自动化定量装车的发展现状和国内油库发油控制系统存在问题的基础上,结合现场总线技术,自适应控制技术、PLC控制技术,设计开发了油库定量发油智能控制系统。该系统实现了油品装车计算机在线控制,自动精确计量,生产动态监测、安全连锁保护、生产数据的自动保存和生产传递报表的打印输出等功能,达到了提高系统装车精度和效率,降低损耗,减轻工人的劳动强度的目的,提高了油库储运系统现代化管理水平。同时为了降低能耗,消除水击和阀门过冲量影响,提高发油精度,本文在对系统发油计量误差组成、发油关断过程进行分析的基础上,提出了电液阀门多级启闭控制方案,完成了定量发油单元的软硬件设计和关阀提前量自整定计算,解决了水击、计量精度低、阀门难以控制、静电等问题。本文主要做了以下几个方面的工作：1、对我国油库自动化控制系统的现状进行了阐述,提出了临潼油库发油控制系统的总体设计方案。2、对临潼油库公路发油定量装车系统的上位机进行了分析、设计和实现。3、阐述油品装车自动精确计量控制办法及方案。4、完成定量发油单元部分的硬件电路和软件编程。5、研究装车流量与剩余量之间的关系,采用阀门多级调控的办法,提高装车效率和精度。
[Abstract]:This paper aims at the demand of automation of oil generating system of oil depot at present, on the basis of analyzing the development situation of automatic and quantitative loading at home and abroad and the existing problems of oil distribution control system in domestic oil depot, combined with field bus technology, Adaptive control technology and PLC control technology are used to design and develop the intelligent control system for quantitative oil production in oil depot. The system realizes on-line control of oil product loading, automatic accurate measurement, dynamic monitoring of production, safety chain protection, etc. The functions of automatic storage of production data and printing and output of production transmission report forms have achieved the purpose of improving the loading accuracy and efficiency of the system, reducing the loss and reducing the labor intensity of the workers. The modern management level of oil storage and transportation system is improved. In order to reduce energy consumption, eliminate the influence of water hammer and valve overimpulse, and improve the accuracy of oil production, this paper analyzes the composition of the system oil generating measurement error and the process of oil generating shutdown. The multi-stage opening and closing control scheme of electro-hydraulic valve is put forward. The software and hardware design of the quantitative oil generating unit and the self-setting calculation of the closing valve advance quantity are completed. The water hammer is solved, the measuring precision is low, and the valve is difficult to control. Static electricity and other problems. This paper mainly do the following aspects of work: 1, the status quo of automatic control system of oil depot in China is expounded. The overall design scheme of the oil distribution control system of Lintong oil depot is put forward, and the upper computer of the highway oil distribution quantitative loading system of Lintong oil depot is analyzed. Design and implement. 3, expound the control method and scheme of automatic accurate metering of oil product loading, complete the hardware circuit and software programming. 5, study the relationship between loading flow and residual quantity, adopt the method of multistage control of valve. Improve loading efficiency and accuracy.
