The Design Of The Real-time Remote Monitoring System For Bridge Deformaiton Based On Geo-robot

Bridges have been built up in abundance in megapolis such as Chongqing, Shanghai, Wuhan etc. with the fast devolopment of national basal construction. It is impotant to carry out safety monitoring for bridge to make sure that the economy of the city could be running well. In order to promote automation,intelligentize in bridge deformation, a research has been done to design the real-time remote monitoring system due to the characteristic of bridge in Chongqing.The auto-monitoring system is made up of two parts,remote monitoring system and Geo-automeasurement system. The latter has the function of data collection and data processing according to the particular setting and make a feedback based on the data by setting the rank and interval of measurement. Remote monitoring system is able to make data remoto transfering and command sending come true. Moreover,it also could remind the Geo-automeasurement system to combine with manual action in special circs to make sure that the measurement is underway in normal.This thesis includethe following contents:Firstly, introduction shows the basic function of Geo-robot. Geo-robot has the function of simple auto-measurement. At the same time, there are program ports in Geo-robot,so that we coule design a more complicated auto-measurement system by using these ports to combine the simple auto-measruement function together so as to achieve complex task of measurement. Then, the effection of Geo-auto-measurement system made in China is analyzed in the thesis comparing to the Leica survey software. Geo-auto-measurement system is the basis of remote monitoring system, and its effection is fit for the demand of designing remote monitoring system.Secondly, in this chapter the serial ports and protocol,designing flat and some notice for system designing are introduced in this chapter. Wireless communication is the main mode used in the remote monitoring system in which the GSI port, ASCII protocol and GeoCom port are used respectively.Thirdly, idiografic research has been done in the system design to make the system put into effect. Function demanding of Geo-robot and remotemonitoring system for auto-measurement system, design for the project, and the fuction of the software are analyzed in this section. There are six parts of the remote monitoring sysytem, project management, system setting, initial measurement, auto-measurement, data process and result outputing, whose function achieved by programming.Analyzing the effection of using the system in the bridge deformation in Chongqing comes last. This segment include the contents of project, carrying field work into execution, the steps of how to control the remote monitoring system, and analysis for the result of measurement. The ideology of this thesis shows that the system could do well in the vested measure task and has the ability of dealing with the paroxymal occurrence as we hoped at the very beginning.
