Development And Application Of Road Maintenance Decision Data Acquisition System For Intelligent Transportation

In order to solve the problems of traditional highway maintenance decision-making data collection methods,such as low collection efficiency,inability to collect road condition panoramic image information,measurable image data,and poor data accuracy,this article analyzes and studies the development of highway maintenance data collection equipment at home and abroad.In order to carry out research on system software and hardware architecture design and acquisition module control design,the design and development of intelligent trafficoriented highway maintenance decision-making data acquisition system.The main research contents of this article are as follows:1)The overall architecture design of the acquisition system.Analyze and compare the architecture modes of highway maintenance decision data collection systems at home and abroad,and combine the characteristics of the GIS software system to carry out detailed system architecture design,software and hardware module division and function design,and collection modules between intelligent transportation-oriented highway maintenance decision data collection systems.Communication link design,acquisition project life cycle design,etc.,lay a solid foundation for the stable operation of the system.2)Design and develop the hardware and software layers of the system.Fully consider the hardware and circuit characteristics of each module,carry out circuit design,hardware module control design,communication method design,embedded software design,etc.,and complete the development of the hardware layer.At the same time,combined with the hardware structure of each module,use the WPF interface framework and C#development language to complete the development of the corresponding control software layer.Finally,design and package all the software and hardware modules,and complete the development and debugging of the acquisition system.3)Application research of acquisition system.Using the maintenance decision data acquisition system designed and developed in this paper,the test highway is used to collect data,and the collected data is analyzed for usability to verify the validity and practicability of this research.The application practice shows that the intelligent traffic-oriented highway maintenance decision data collection system designed and developed in this paper has a reasonable architecture design,modular design and system software and hardware layering are in line with the idea of high cohesion and low coupling,and the system has strong adaptability and high collection efficiency.The system has the advantages of stable system operation,high data accuracy,and powerful functions,and has broad application prospects.
