Monitoring System Of Asphalt Material Mixing Ratio Used In Video Analysis

The asphalt mixing material ratio has a direct impact on the quality of the asphalt pavement, but there is not an effective monitoring method to prevent the mixing material ratio information from being tampered until now. On the basis of analyzing various domestic and international monitoring systems, this paper designs the asphalt mixing materials ratio monitoring system based on video analysis. This realizes the rapid and real-time monitoring of asphalt mixing materials ratio information.This paper mainly studies the video collection, video processing and analysis of the results, display, storage, and other key technical problems of the asphalt mixing material ratio monitoring system. After comprehensive analysis of field and actual circumstances, this paper introduces the working principle, hardware structure, the software design and realization method of video monitoring system in detail. And the video collection and analysis techniques are mainly studied. Under the platform of the high speed digital signal processor, this paper puts forward a method that using the video collection technologies to realize the method of capturing actual ratio of asphalt mixture and mixing station mechanical operation action. Finally, this paper designs the information transmission algorithm based on combining of wireless network and wired network to realize the remote monitoring of the mixing materials ratio. This can finish the remote monitoring and warning of the asphalt mixing and station's mixing materials ratio information rapidly and accurately.The asphalt mixing material ratio monitoring system proposed by papers has been used in highway construction site data information monitoring. It realizes the rapid collection of proportion and temperature information of asphalt mixture, the interactive retrieval and display of massive data information The system provides fast and effective techniques for asphalt pavement construction information management, road construction schedule and road construction performance evaluation. It can effectively enhance the assessment and management level of the asphalt road construction in transportation.
