Study On Brige Remote Monitoring System Based On Internet

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.As the fast development of communication technology, 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 Chip Micyoco, 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 works in detail, gives the final result of the application program, analysises the problem happened in the system and gives the way to resolve them. The design includes two parts: (l)hardware: the hardware system is mainly structured by distributed Single Chip Micyoco data processing system based on RS-485 bus;(2)software: this part designs the SCM program by C language, We use Visual Basic to design the Client and the Server application program, the whole software includes COM port communication program and remote data transmission, we also use SQL server 2000 to build the remote database system.Huge bridges have long interspace span, many binding point and complex structure, it involves many fields such as architecture, mechanics,communications, model identification, data fusion and error analysis, it is a popular research field in the world today, there still have many subjects waiting for us to resolve.
