【摘要】：从上世纪八十年代起,计算机信息技术进入石化行业,伴随着人们不断地进行研究设计、工艺改造、生产控制、计划优化以及供应链优化,计算机的过程控制技术的广泛应用得到更深一步的发展,在经营决策等方面取得了飞跃式的进步,预期影响还将继续深化改革发展下去,先进的过程控制技术(APC)和计算机网络技术在石化行业中的结合后,可以整合化学数据与实时图像。仿真模拟技术以及工艺流程图的绘制,更加准确的描绘了整个过程,实现了全厂优化并延伸至整个企业。在网络及计算机飞速发展的今天,针对这方面的信息管理就迫切需要一个行之有效的系统来进行维护操作,提高实验设备使用效率。这对于学校设备、实验员和管理者都至关重要。学生的日常实验课程的部分内容通过可视化变成语言展示,以实现对实验室内部设施更好、更快、更精准的管理。怎样通过网络及计算机软件系统来管理实验装置,想做好这方面就必须熟悉设备的工作原理,解决关键性的难点问题及对数据与设备链接进行处理,从实验室工作实际出发,在这种前提条件下就需要一个合理可行的软件系统来完成需求,因上述几方面综合现状可以看出实验过程中比较繁琐的数据采集以及图表绘制的工作,这样就迫切需要研制开发一套基于网络的具有规范化、现代化的综合化工计算机过程控制系统。让实验员与学生从复杂烦琐工作中解放出来,提高教学质量,降低实验损耗。为了使实验教学与现代化工计算机过程控制系统紧密的结合,本文对学校的学生动手能力、观察能力、综合分析和处理问题的能力进行分析,对学生进行测试调研,只有了解了学生在日常学习过程中的短板,并加以分析,才能明确实验的教学重点,有目的的对过程控制实验课进行设计。主体设备的工艺设计,附属设备的选型设计,主体设备总图的绘制,是完成单独一个化工单元操作的重要三个步骤。另一方面为了实现需求,针对开发。针对开发语言也进行了排优处理,所开发的这个系统所采用的是SQL Server2000,其功能在系统内部有源代码直接完成。在ASP.NET中可以通过不同的语言进行编写,包括C++和Java。当浏览器请求ASP.NET文件时,ASP.NET引擎读取该文件,编译并执行文件中的脚本,然后以纯HTML向浏览器返回结果。我们只需按过程控制系统要求输入即可操作。这样就方便了开发人员的可重用性的要求。
[Abstract]:Since -20s, computer information technology has entered the petrochemical industry, with the continuous research and design, process transformation, production control, planning optimization and supply chain optimization. The wide application of computer process control technology has been further developed, and has made great progress in management decision-making, and the expected impact will continue to deepen the reform and development. The combination of advanced process control technology (APC) and computer network technology in petrochemical industry can integrate chemical data with real-time image, simulation and process flow chart drawing. More accurate description of the whole process, the realization of the plant optimization and extension to the entire enterprise. In the network and computer rapid development today. In view of this aspect information management urgently needs an effective system to carry on the maintenance operation, enhances the experiment equipment to use the efficiency, this is for the school equipment. Both the experimenter and the administrator are critical. Part of the student's daily experimental course is visualized into a language presentation to achieve better and faster facilities within the laboratory. More accurate management. How to manage experimental devices through network and computer software systems, if you want to do a good job in this respect, you must be familiar with the working principles of the equipment. To solve the key and difficult problems and to deal with the data and equipment link, we need a reasonable and feasible software system to fulfill the requirements under the premise of the actual work in the laboratory. As a result of the above several aspects of the synthesis of the status quo can be seen in the experimental process of the more cumbersome data collection and chart drawing work, so it is urgent to develop a set of network-based standardization. The modern computer process control system of comprehensive chemical industry can free the experimenters and students from the complicated and tedious work and improve the teaching quality. In order to combine the experiment teaching with the modern chemical industry computer process control system, this paper analyzes the students' ability of operation, observation, comprehensive analysis and problem solving. In order to make clear the teaching focus of the experiment, only by understanding the students' short board in the course of daily study and analyzing it, can the students be tested and investigated. The process control experiment course is designed. The process design of the main equipment, the type selection design of the subsidiary equipment, the drawing of the main equipment general plan. On the other hand, in order to achieve the requirements, for the development of the development language also carried out optimization processing. This system is developed using SQL Server 2000, its function in the system has the source code directly completed. In ASP.NET can be written through different languages. Includes C and Java. when the browser requests a ASP.NET file, the ASP. Net engine reads the file, compiles and executes the script in the file. Then we return the results to the browser with pure HTML. We only need to input according to the process control system requirements, which facilitates the reusability requirements of the developers.
