Design Of Group Fog Detection And Early Warning System Based On Image Analysis

With the long-term and stable development of China's economy,the total mileage of highway is increasing.By the end of 2015,China's total mileage of the highway has exceeded 120,000 km.With the increase of highway mileage and the traffic accidents on highway are also increasing.Which traffic accidents caused by fog and other meteorological factors are also increasing.Fog has the characteristics of short time,small coverage and short duration.Due to the low visibility environment created by the fog,the enormous loss of life and property of the people of the society is caused.Therefore,in order to prevent the fog problem and design and development of a set of effective,low-cost group fog detection and early warning system has a very important significance.According fog occurred a short time,small-coverage and other characteristics,this paper presents a fog detection warning system based on image analysis.The system is based on software engineering design principles developed by the collection side and the server side of the two major components.In the collection side,we can use long-range laser launch laser transmitter,use the principle of laser scattering in the fog,collect the scattered laser spot image that reflected the fog level after long-distance transmission.We conduct a series of fog level detection based on the resulting laser image.At the same time,we use the collection side of the mobile communication module,send the real-time image data to the server side.In order to achieve on the server side of the entire highway collection side of the all-weather real-time group fog early warning.At first,the paper describes the theory and practical significance of studying the early-warning system of mass fog on the expressway,and compares and analyzes the existing group fog detection technology.Secondly,this paper puts forward the scheme of fog detection warning system based on image analysis,and analyzes the laser-based fog detection principle and implementation steps.Then the hardware design and software design of the early warning system are put forward based on the design principle of software engineering,and all the modules involved in the system are described and analyzed in detail.Then the paper gives the software design of each function module of the system.At last,the simulation experiment of the group fog detection and early warning system is carried out,and the result of the whole system is given.
