| With the rapid development of field bus technology, embedded technology, networkcommunication technology and image acquisition technology, the traditional industrial controlsystem gradually becomes intelligent and small. This paper discusses a multi-functional industrialproduction control system which consists of the lower machine and the host computer. Combinedwith industrial-grade chips AT91SAM9G45and embedded Linux system, this system realizes notonly data collection, data transmission and data presentation, but also SMS alarm, remote videomonitoring and power line transmission. The host computer processes data coming from the lowermachine and then displays them, it transfers configuration parameter to the lower machine at thesame time. Now this multi-functional industrial control system runs well in the industrial hydrogenenvironment, and it meets the expected design requirements.This paper describes design flow of the multi-functional industrial production control systemas well as its application in industrial hydrogen. Specific content includes:Firstly, this paper introduces the research background and significance, also it statesdevelopment process of the industrial control system.Secondly, this paper makes a detailed analysis of the needs of the multi-functional industrialproduction control system, including the lower machine and the host computer, and then determinesusing Client/Server model between the lower machine and the host computer.Thirdly, this paper introduces the lower machine, including hardware design and softwaredesign. Software design involves bootloader, kernel and QT/E file system.Fourthly, this paper illustrates the host machine at length, it includes GUI design and databasedesign. And industrial hydrogen production system is stated as an example.Finally, remote video monitoring and power line transmission are introduced in detail. |
