Research On Vehicle Information Management And Monitoring Problem Of Agricultural Material Distribution For Chain Operation

Along with the rapid development of economy in China and the government attention to rural issues, agricultural Material industry for chain operation facing main towns has become a important force driving the rural economy, and also become active in the development of modern service industry in the village. However, improper use of vehicles, poor communication and other reasons result in a lower load rate of vehicles, it has led to low efficiency of delivery and high distribution costs, and hamper the healthy development of agricultural material enterprises for chain operation. Therefore, it makes important theory and realism significance to do research and development on vehicle information management and monitoring system of agricultural Material distribution of chain operation facing main towns.The thesis firstly analyses industry characteristics, current situation, types of material and vehicle of agricultural Material distribution of chain operation facing main towns, and the status of vehicle monitoring in the entire logistics process, vehicle monitoring elements of various stages in the distribution, at the same time establishing a distribution system for quality evaluation of transportation from the safety, timeliness, economy after distribution; Then conduct system requirements analysis, functional design, framework design of vehicle information management and monitoring system, based on the system requirements features of agricultural material distribution of chain operation facing main towns; In order to achieve the system requirements and design goals, divide the system into three aspects and select related technologies, ultimately communication interface aspect introduce positioning technology of GPS and communications technology of GPRS, data services aspect Access database and user interface aspect GIS software of Mapinfo. Establish emergency dispatching model based on Mapinfo and improved shortest path algorithm; Finally using the C sharp language to operate Mapinfo on the platform of Visual Studio.NET by Mapxtreme, program to realize the functions of vehicle monitoring, path playback, vehicle path planning, emergency dispatching with Access. In addition, design example for the system application, the experimental results show that the software has the features of clear interface, simplified operation and ideal applied effect.
