【摘要】：目前，工业领域对气体制造的监控一般都采用PLC来实现，虽然PLC具有开发简单，运行速度快等特点，但是其价格比较昂贵，而且在与PC进行互联通信时，需要PLC开发商提供的系统协议和网络适配器，这无疑更增加了系统投资，也使其在应用的灵活性上受到一定的局限性。随着嵌入式技术的不断发展，嵌入式处理器性能的不断提高，如今嵌入式产品在这一领域的应用增长迅速。 本论文主要设计了一个基于三星S3C2440嵌入式实时监控系统，，它能广泛应用于工业上的制氢、制氧或其它气体制造的监控上。该监控系统主要由监测终端、通信网络、监测中心组成，通过实时监测生产制造现场的气体制造压力、工作温度、气体存储压力、直流工作电压、气体泄露浓度等技术参数并实现现场实时显示、数据分析判断、系统异常报警等功能，建立了一种实时监测多点接警的安全保障模式；监测终端所采集的数据通过网络实时发送到上位机，改变了单一人工巡视的工作方式，提高了工业气体制造的安全性。 本论文首先介绍了监控系统的硬件平台和各个组成模块，紧接着阐述了如何构建基于S3C2440的软件开发平台，包括u-boot的移植、Linux内核的裁剪和Qt文件系统制作。最后，设计了该监控系统的上层应用软件，包括数据的实时显示界面、数据的实时采集、系统异常报警和数据的网络发送。 最终，本论文所设计的产品被成功运用到了对制氢设备监控的工程实践中。
[Abstract]:At present, the monitoring of gas manufacturing in industrial field is generally realized by PLC. Although PLC has the characteristics of simple development and fast running speed, it is relatively expensive, and when communicating with PC, it needs the system protocol and network adapter provided by PLC developer, which undoubtedly increases the system investment and makes it suffer some limitations in the flexibility of application. With the continuous development of embedded technology and the continuous improvement of embedded processor performance, the application of embedded products in this field is growing rapidly. In this paper, an embedded real-time monitoring system based on Samsung S3C2440 is designed, which can be widely used in industrial monitoring of hydrogen production, oxygen production or other gas manufacturing. The monitoring system is mainly composed of monitoring terminal, communication network and monitoring center. By monitoring the technical parameters such as gas manufacturing pressure, working temperature, gas storage pressure, DC working voltage, gas leakage concentration and so on in real time, and realizing the functions of real time display, data analysis and judgment, system abnormal alarm and so on, a safety guarantee mode of real time monitoring multi-point alarm is established. The data collected by the monitoring terminal are sent to the upper computer in real time through the network, which changes the working mode of single manual inspection and improves the safety of industrial gas manufacturing. This paper first introduces the hardware platform and each module of the monitoring system, and then expounds how to construct the software development platform based on S3C2440, including the transplantation of u-boot, the cutting of Linux kernel and the making of Qt file system. Finally, the upper application software of the monitoring system is designed, including the real-time display interface of the data, the real-time acquisition of the data, the abnormal alarm of the system and the network transmission of the data. Finally, the products designed in this paper have been successfully applied to the engineering practice of monitoring hydrogen production equipment.
