Study On Agilor Real-Time Database In HongFengHu Bridge Healthy Monitoring System

Bridge health remote monitoring is a method to monitor a bridge in lineate or wireless way in real time, it changes the traditional way of monitoring by manpower, works more automatically, highly increase the response speed when any structure breakage is happened, save manpower and material resource, through this method, people can also manage many bridges in one place remotely.This paper makes full use of the real-time database technology applying in the management of the temperary data, and it turns into a convenience way to transmit data through Internet between long distance, the author uses this method in this paper. This bridge health remote monitoring system consists of three parts: data acquisition, data transmission and data processing. The first part is a distributed system consists with Single ChipMicyoco, this part is designed to gather the state information of the bridge and send the data to computer as certain mode; The second part is designed to transfer the data to the clients in remote control center through Internet; The third part consists of database system and analysis system, it proceses the data and gives a final conclusion.The paper gives the process of how to design the whole application system, describes how the Client terminal and the Server terminal programs in detail. The main work of this paper includes: (1)analyzes the principle and steps of SDT and PLOT algorithm, which are two kinds of the real time data compression methods, the improved algorithm are given based on it; (2) use Agilor Real-Time database to build the remote database system; (3) use Visual C# to design the Client and the Server application program.The whole program includes data collection of girder vibration and remote data transmission in C/S mode.
