Aiming at shortcomings of traditional steel corrosion monitoring methods

a kind of wireless monitoring system for corrosion degree of reinforcement in concrete based on wireless sensor networks（ WSNs） is proposed.The system combines WSNs technology with electrochemical method for reinforcement corrosion monitoring

track and measure corrosion potential of reinforcement in concrete structures by using MnO2 solid-state reference electrode

low power consumption chip CC2530 is choosen as RF transceiver of WSNs node

and potential signal collected by WSNs nodes is sent to upper PC through WCDMA network and the Internet. Upper PC uses Lab VIEW software to design a set of personalized monitoring interface

show information of concrete reinforcement corrosion.Experimental results show that collected potential signals by system can well reflect degree of reinforcement corrosion

it has stable performance and strong reliability.
