WSN-based remote wireless monitoring system for concrete reinforcement corrosion degree

Abstract

The invention discloses a WSN(Wireless Sensor Network)-based remote wireless monitoring system for concrete reinforcement corrosion degree. The system is characterized by being composed of a plurality of sensor data acquisition nodes, an embedded gateway and a remote data monitoring center; the sensor data acquisition nodes are distributed at each test point of a concrete structure test region, and are used for acquiring corrosion potential value of the reinforcement in a large concrete structure and processing the data, and then, transmitting the data to a coordinator node; the coordinator node processes and analyzes the received data, and further transmits the data to the remote monitoring center through a WCDMA (Wideband Code Division Multiple Access) or Internet communication mode; finally, a monitoring management center stores, processes and analyzes the received data, and upper computer software displays corrosion data of the reinforcement in the concrete structure. The system provided by the invention solves the problems of failure in implementation of dynamic continuous monitoring and heavy workload in the traditional electrochemical methods for monitoring reinforcement corrosion degree, such as a half-cell potential method, a linear polarization method, an alternating current impedance method and a macro cell corrosion current method, and also effectively solves the problem that signals are easily disturbed in a traditional wireless transmission mode using an electromagnetic oscillation circuit.

Description

technical field [0001] The invention relates to the technical field of wireless monitoring, in particular to a remote wireless monitoring system based on WSN concrete reinforcement corrosion. Background technique [0002] The durability of concrete is a major issue in the field of civil engineering today, and the corrosion of steel bars is an important factor affecting the durability of concrete. According to the official website of the State Administration of Work Safety, in the past five years, at least 17 bridges across the country have collapsed, causing nearly 300 casualties. Among them, concrete damage caused by corrosion of steel bars is quite common. [0003] At present, electrochemical methods such as half-cell potential method, linear polarization method, AC impedance method, and macro-cell corrosion current method have become hot methods at home and abroad to study the corrosion degree of steel bars, but these methods have not yet realized real-time dynamic contin...
