摘要随着水下结构的日益增多，在一些结构的损坏案例中水流的冲刷作用所占比例也是越来越大。洪水导致的桥梁墩台基础的冲刷是引起桥梁失效的常见原因。不仅对于桥梁问题，大坝和码头的淤积问题等都对该水利设施造成了严重的破坏。30429

Title Research and development on the data demodulator of thermal bridge sensor system for the depth of scouring and deposition
Abstract
With the increasing number of underwater structures.In some cases of structure damage,the proportion of the damage caused of water erosion is growing.A common cause of bidge failure is the scour of bridge pier foundation caused by a flood.Besides,siltation problem of dam and marina also caused catastrophic damage.
According to the urgent phenomenon above.this graduation project is going to develope this kind of sensor system for the depth of scouring and deposition.With this system ,we can monitor the position of the interface of water and soil on real time.The main architecture of this system is the 89C52RC chip manufactured by STC.This system is designed to analyse an process the data sended back to the demodulator by the sensor installed below water.After processing the data ,the system will send some pivotal information to our client through the internet of things . The demodulator is powered by the solar cell.And the sensor will be powered by the demodulator .At the same time,my graduation project will set a standard algorithm for processing data.
