Aiming at the requirement of safety monitoring in bridge construction and operation

a multi-channel and multi-point wireless bridge strain monitoring system based on Zig Bee is proposed. This system acquires multipoint strain data and wirelessly transmit the data to gateway and upper personal computer（ PC） via multi-channel based on CC2530 and STM32

then uploads data to cloud sever

thus overcomes the problems of high cost

complex wiring

and difficult maintenance in traditional bridge monitoring system. The experimental results show that the system can monitor static and dynamic strain wirelessly

which meets the requirement of bridge state monitoring.
