Abstract:In order to solve being low in monitoring efficiency of unattended field and remote monitoring system resulted in that the exchange of data and information is not fluency, the paper explored an implementation of unattended field and remote monitoring system based on sensor Web. In the paper, it expounded differences between sensor networks and sensor Web, researched wireless sensor networks and their networking, constructed a framework of unattended field and remote monitoring system based on sensor Web, and designed and implemented an unattended field and remote monitoring system based on sensor Web. Taken a constructed unattended field and remote monitoring system based on sensor Web as an example to monitor water body pollution in a certain water area, the actual test data verified its rationality of the designed and implemented system. The research result shows that it is feasible for designed unattended field and remote monitoring system based on sensor Web.
