Networked monitoring system based on embedded dynamic web
Aimed at the difference in communication protocol among dispensers, resulted in being difficult to realize the monitoring system integration, this paper presented a sort of integrated monitoring solution based on embedded Web. The core device of monitoring system chose a sort of embedded Web server based on Intel Xscale IXP-422 RISC CPU. The servers distributed in the industrial field of gas stations were interconnected through industrial Ethernet, and composed a wide area network system based on Web service. The field bus of field device connected to Web server in the field local area of gas stations to complete the integrated monitoring of field device. The system adopted the architecture of distributed browser / server. By means of the approach of Apache + HTML + PHP, the monitoring and management of the gas stations could be realized based on embedded Web, and the realization of dynamic Web browse could be completed by control unit. The results of the practical test show that it is available in reality, and provide a better solution to realize the networked monitoring.
