Study on Intelligent Monitoring and Control System for Crack Prevention of Concrete Dam

Abstract

This intelligent monitoring and control system was developed for the purpose of preventing the cracks and improving the quality of mass concrete constructions. It is composed of four parts, including perception, interconnection, analysis and decision-making, and control. The system has realized the automatic perception, transmission, and sharing of temperature control information, and intelligent control in related key sections throughout the processes of raw material precooling, concrete mixing, concrete transportation, concrete placemen, concrete vibration, concrete water cooling, and concrete surface maintenance. Meanwhile, the system has realized the management of all factors and the entire process of temperature control and crack prevention by means of a kind of rebuilt networking combination which is based on Zigbee and internet technique. This system has been applied in four large China’s concrete dams. Engineering applications show that the system can help improve the management level and prevent cracks during concrete construction.
