It's the essential approach to realize the accurate and reliable control by the integration of corrosion monitoring and control system for the major reinforced concrete (RC) structures. This project aims to achieve the wireless energy-harvesting corrosion monitoring and cathodic protection (CP) control integrated autonomous system based on the Smart Planet concept. The research is conducted as follows: (1) Investigate the simulation approach based on the Boundary Element Method (BEM) for the electric field throwing in the concrete with the complex boundary and internal conditions, then to establish the optimization algorithm based on the Graph Theory for the distribution of anodic electrodes, and the reliability of these methods are finally verified by the in-situ monitoring experiments of RC elements. (2) Establish the PHREEQC model to characterize the interaction of the ion swarm in the pore solution and the pore wall of concrete, then to obtain the algorithm for the evolution of the particle field coupling the electric field in the concrete during the CP process, and the reliability of these methods are finally verified by the ion swarm monitoring and detection experiments of RC elements. (3) Study the methodology of building energy-harvesting wireless motes that can monitor multiple corrosion-related events and propagate data with ultra-low power consumption, and then establish the wireless-network-based CP system supporting highly efficient data delivery and real-time adaptive control. (4) Integrate the corrosion monitoring and CP control prototype autonomous system for the major RC structures, then to verify the reliability of this integration system on the RC bridge models with the joint action of the typical corrosive environments. This project has the significant academic value, remarkable economic benefits and broad application prospects.
