Abstract
The invention relates to an intelligent levee probing and warning method based on a wireless sensing network. The method finishes the timely exchange and resource sharing of the observed data of each probing point of the levee on the basis that a wireless transmission network has flexible erection, rapid implementation and low cost and is not limited by regions, and by the wireless transmission network, thus realizing the real-time monitoring and warning of a monitoring center to all the probing points of the levee. The method of the invention overcomes the deficiencies that the current levee probing has high real-time monitoring difficulty due to the long length of embankment; probing scope is limited and timeliness is bad due to the point-to-multipoint dispersed network of the monitoring network and as each point has short or long distances to the monitoring center, the levee probing is web-based and intelligentized with benefit based on the wireless sensing network, thus improving the real-time degree of the safe probing of the levee and realizing the wide range and high-real time non-destructive levee probing and warning.
