In order to better ensure the quality of road construction, construction personnel's life and property security, peace and harmonious society construction, for the masses to provide a convenient, comfortable and safe space, need for highway construction monitoring and control system design. The current highway construction monitoring and control system design method is to use image processing surface monitoring, monitoring the process of image processing board size is too big, no concealment barriers, lead to monitor the blind spots, more is to monitor the overall performance is low, problem of poor effect of monitoring and control system. For this, put forward a kind of highway construction intelligent monitoring system based on the geometric control design method. Types, this method first determine highway construction monitoring and monitoring system for construction of highway construction, and then on the basis of the structure of the highway construction monitoring and control system, using code awareness routing, each terminal monitoring data information transmission to monitor and control system center, finally USES the serpentine time slot data storage algorithm of highway construction to the terminal monitoring information data storage, thus complete the system design of the intelligent monitoring of highway construction. Experimental results show that the proposed method can be full of highway construction, safe and reliable intelligent monitoring, reduce the processing time and monitoring blind spots and emergencies, increased the speed of road construction, a greater degree to the protection of the personal safety of the construction personnel, in the field of research and development provides a strong basis.
