【摘要】：随着我国人民生活水平的不断提高和城市化建设步伐的加快,水泥成为必不可少且越来越重要的基础原材料,它在国民的经济发展中占有非常重要的地位。同时,水泥企业是高耗能、高排放的源头,只有对水泥生产数据实时、无误地掌握,水泥企业管理者才能实现对水泥企业能源消耗的精细化管理,达到低消耗、低排放的目标。因此,生产数据采集系统在水泥企业中有着至关重要的作用。国内的数据采集系统存在很多问题,主要体现在以下两个方面,一是CPU资源利用不充分,二是任务之间独立性差、系统的可靠性低。针对数据采集系统存在的上述问题,本文以.NET为开发平台,使用C#语言,并结合多线程技术的优势和特点,设计基于多线程技术的水泥企业生产数据采集系统。本文的主要工作包括:(1)研究.NET平台下多线程技术,对线程的分类、实现和操作做了深入的研究和掌握。(2)研究水泥生产的工艺流程,掌握各工序的功能和结构,分析水泥企业生产数据的结构和特点,并给出电能数据的采集点。(3)提出水泥企业生产数据采集系统的网络结构,描述了主要的网络接口,并对相关的通信技术SerialPort类、OPC技术作了深入的研究。(4)根据多线程技术的思想,设计出本系统的软件框架,对主线程的全局变量声明、初始化、线程操作模块,以及子线程的串口数采线程、电力需求侧线程、OPC数采线程进行详细的设计和介绍。(5)设计并创建出分厂数据库和生产线数据库,使用C#语言开发、实现水泥企业生产数据采集系统,并给出电能数据的采集成果。
[Abstract]:With the continuous improvement of people's living standards and the acceleration of urbanization construction, cement has become an indispensable and more important basic raw material, which plays a very important role in the national economic development. At the same time, cement enterprise is the source of high energy consumption and high emission. Only by mastering the cement production data in real time and unmistakably, can the managers of cement enterprises realize the fine management of energy consumption in cement enterprises and achieve the goal of low consumption and low emission. Therefore, the production data acquisition system plays an important role in cement enterprises. There are many problems in the domestic data acquisition system, which are mainly reflected in the following two aspects: one is that the CPU resources are not fully utilized, the other is the independence between tasks is poor, and the reliability of the system is low. Aiming at the above problems in the data acquisition system, this paper designs a cement enterprise production data acquisition system based on multithreading technology by using C # language and combining the advantages and characteristics of multi-thread technology with .NET as the development platform. The main work of this paper is as follows: (1) the multithreading technology under .NET platform is studied, and the classification, realization and operation of threads are deeply studied and mastered. (2) the technological process of cement production is studied, and the function and structure of each process are grasped. The structure and characteristics of production data in cement enterprise are analyzed, and the collection points of electric energy data are given. (3) the network structure of production data acquisition system in cement enterprise is proposed, the main network interface is described, and the SerialPort class of related communication technology is introduced. The OPC technology is deeply studied. (4) according to the idea of multi-thread technology, the software frame of the system is designed, the global variable declaration of main thread, initialization, thread operation module and serial port thread of sub-thread are designed. The power demand side thread and OPC data collection thread are designed and introduced in detail. (5) designing and creating the branch database and production line database, using C # language to realize the production data acquisition system of cement enterprise, The acquisition results of electric energy data are also given.
