【摘要】：当前，现场总线技术已经广泛应用于工业现场和实验室中，它可以给设备以可靠的连接和控制，技术非常成熟。但现场总线是一种专用网络，控制的物理空间扩大时将会大大增加监控系统的成本。随着近年计算机技术和计算机网络的快速发展，计算机网络已经延伸至学校、工厂、实验室等各个角落，通过无线连接，人们甚至可以随时随地接入网络。所以，如果能够将传统的计算机网络与工业控制相结合，必将大大降低监控系统的成本，，提高其便捷程度。现如今，由于TCP/IP技术和嵌入式技术的逐渐成熟，B/S模式应用越来越广泛，使工业设备的网络化监控提供了较好的技术基础，必将成为一种新的发展趋势，具有广阔的发展前景。本文以水温作为控制对象，按照现在比较流行且技术上已经较为成熟的B/S模式，将系统的数据采集、数据控制、数据接口、数据存储和网络控制等功能划分为4个功能模块：1、设备数据采集/控制模块；2、CGI数据接口网关模块；3、数据存储模块；4、Web数据监控模块。其中，数据的交互以CGI技术为核心，实现了数据采集设备与网络控制、数据存储两个模块的交互，使用户可以从服务器上对整个系统进行统一控制操作的功能。为了实现系统设计目标，本文首先分析了当前嵌入式远程监控系统的现状，从嵌入式操作系统软件与硬件等两个方面综合考虑，选择ARM芯片为核心的53C2410处理器作为关键部件，为嵌入式处理器裁剪并配置了嵌入式Linux操作系统，并在其上配置并实现了BOA网络服务器和SQLite嵌入式数据库，使服务器能够通过普通的计算机网络实现温度数据的采集，并实时显示于服务器端。还可以实现系统运行状态的查询、运行参数的设置和开关控制等。经测试检验，本系统运行正常，数据显示与存储，系统参数的设置与开关控制等都完全符合最初的设计要求。本系统不仅实现了工业现场和实验室的远程监控，并且为智能家电的发展提供了一个可行方案。
[Abstract]:At present, fieldbus technology has been widely used in industrial field and laboratory, it can give equipment reliable connection and control, the technology is very mature. But fieldbus is a kind of special network, and the cost of monitoring system will be greatly increased when the physical space of control is enlarged. With the rapid development of computer technology and computer network in recent years, computer network has been extended to schools, factories, laboratories and other corners. Through wireless connection, people can even access the network anytime and anywhere. Therefore, if the traditional computer network and industrial control can be combined, it will greatly reduce the cost of the monitoring system and improve its convenience. Nowadays, due to the maturity of TCP/IP technology and embedded technology, the application of B / S mode is becoming more and more extensive, which makes the networked monitoring of industrial equipment provide a good technical foundation, and will become a new development trend and broad development prospects. This paper takes the water temperature as the control object, according to the more popular and technically mature B / S mode, the system data acquisition, data control, data interface, The functions of data storage and network control are divided into four functional modules: 1: 1, 2 / 2 CGI data interface gateway module, and 4 / 4 Web data monitoring module. Among them, the data interaction is based on CGI technology, which realizes the interaction between data acquisition equipment and network control, data storage module, so that users can control the whole system from the server. In order to realize the design goal of the system, this paper first analyzes the current situation of the embedded remote monitoring system. Considering the embedded operating system software and hardware, the 53C2410 processor with ARM chip as the core is selected as the key component. The embedded Linux operating system is cut and configured for the embedded processor, and the BOA network server and the SQLite embedded database are configured and implemented on the embedded processor, which enables the server to collect the temperature data through the common computer network. And real-time display in the server. It can also realize system running state query, operation parameter setting and switch control, etc. The test results show that the system runs normally, data display and storage, system parameter setting and switch control are all in line with the original design requirements. This system not only realizes the remote monitoring of industrial field and laboratory, but also provides a feasible scheme for the development of intelligent household appliances.
