The Research Of Embedded Web Remote Monitoring

At present, industry mainly by bus in the form of field operation device connected, to achieve control of equipment, the development of embedded network technology makes the field device can realize the network in the field of management, remote monitoring is realized using Web technology has become a new hot spot in the embedded field, and very broad prospects for development.After the design is completed, to the field device the temperature of the water for the monitored object, the application of B/S design pattern to the four main modules of the system:CGI data interface module, data acquisition and control module, monitoring module, database module of SQLite; dynamic data through each module inter building embedded Web remote monitoring system required, CGI data interface module is the core of constructing remote monitoring system, and the system can realize the underlying data acquisition and data control module, data acquisition and storage of data communication and exchange information with the Web data monitoring module, and then using the method of CGI dynamic data interaction, the realization of remote monitoring system.In order to make the system realize the function of design, the first step is to analyze the current status of Web remote monitoring system, through a comprehensive consideration to many aspects of the embedded Linux operating system, the embedded hardware platform and application software, choose ARM9as the core of the S3C2410as the core processor hardware system, monitoring the running environment of embedded Linux operating system, complete the configuration and transplantation of embedded Web Server BOA server and embedded SQLite database according to the design requirement. The final water temperature monitoring of remote devices through the realization of Web server, the temperature real-time display, set the system parameters of communication, data acquisition module8road temperature acquisition, switch control, query system running state and other functions.Experimental tests show that this system can, relatively stable in the range of laboratory LAN in the operation, has a certain practicality. Can realize real-time display of remote data, display channel running status, operational data storage and operation of data backup timing, set the system related parameters, remote switch control system operation state expected design demand function.
