Aiming at problem that bridge health condition monitoring needs to use variety kinds of sensors for data acquisition

which involves different sensor interface

that makes expansion and maintenance of the system very difficult

on the basis of analysis on sensor interface standard GB/T30269. 701 and GB/T30269. 702

standardized design of sensor interface for bridge health condition monitoring system is carried out

and realize bridge condition parameter acquisition terminal and bridge monitoring integrated host computer according to sensor interface standard. The results of the test system show that the system works well and has good scalability and maintainability.
