“…The infrastructure construction scale, mainly civil and hydraulic engineering, has exceeded the total of all other countries in the world every year [6]. The near future will gradually enter the basic construction in China which focuses on service building maintenance phase, in order to ensure the safety of the structure, reduce the economic loss and casualties, try to improve steel bar corrosion resistant ability, and extend the service life of structure and real-time control of the steel corrosion of reinforced concrete major projects at the same time; the safety performance has become more and more important [7]. The development of high durability testing technology and the long-term monitoring and evaluation technology for the corrosion and damage evolution characteristics of reinforced concrete structure have significant technical support for the safety of major projects of reinforced concrete structure and have achieved significant economic value and strategic significance.…”

Reinforced concrete structures are widely used in modern buildings such as buildings, bridges, and tunnels. However, the structural damage caused by reinforcement corrosion seriously affects the service life of the buildings. Because the corrosion of reinforcement in concrete is a very slow process, the continuous detection of reinforcement corrosion is very important. In view of the slow development of steel corrosion detection equipment in China, which cannot meet the application requirements of concrete structures in China, wireless monitoring technology has more advantages than traditional monitoring technology. In this paper, combined with wireless transmission technology, a concrete reinforcement corrosion detection system based on wireless sensor network is designed. Embedded sensors based on the principle of electromagnetic coupling are used to collect steel corrosion information. It is determined that the 16-bit ultralow power consumption microcontroller MSP430F149 is the main control chip, the AD9850 based on DDS technology is the signal generation chip, and the nRF905 is the detection circuit scheme of the wireless transceiver chip. The star network is determined by polling the entire network topology and MAC protocol. The embedded sensor is designed through simulation. This article discusses the principle of using embedded sensors to detect steel corrosion and determines the feasibility of its low-cost implementation. The embedded sensor and steel corrosion detection system were tested. The simulation method of the embedded sensor is verified through actual measurement. The test results show that the system network is normal and all parts work stably, which can meet the requirements of the project.
