Monitor System Of Railway Intelligent Power Supply Based On Embedded System

With the rapid development of computer technology, intelligent monitoring technology is also applied in the field of railway signal power supply .Combination of electronic technology and intelligent monitoring technology makes power supply panel have the function of real-time monitoring, alarm record and locating the malfunction. At present, the majority of monitoring system use the way of C/S, which have promoted a lot, but exist some disadvantages. With the development of internet, the way of B/S is more and more applied in the field of industrial monitoring, which saves a lot of cost in remote monitoring. User can monitor remote devices at any time and any place by IE browser.Aim at remote monitoring of railway power supply, this paper researches on software and hardware design of embedded web server based on the arm9.The core of hardware part is S3C2410 processor produced by Samsung, which is the RISC style based on ARM920T kernel. The software part has adopted Linux operating system, which source code is open. The Boa embedded web server, which is replanted on S3C2410 processor successfully, combines with CGI dynamic website technology to realize network remote monitoring function. This function is applied in the railway signal intelligent power supply monitoring.In order to realize nobody guard, this paper also designs the video monitoring system based on the platform of Intel PXA270 for machine house environment of power supply, and designs scheme of network monitoring.
