Driven by economic interests,carriage overloading phenomenon is very common,casualty that caused by the overloading frequently occurs.In order to obtain the image information inside the carriage,as well as meeting the requirements of the integrated management of long distance carriage by the traffic management departments,wireless remote image monitoring project that based on the information of overloading and overspeed of the carriage is proposed for the long distance carriage.The monitoring project is designed with the GPRS,digital image processing, GPS positioning technology,and a MCU based on ARM Cortex-M3 core is used as its primary control module.The capturing,storage and wireless transmission of the information of image,overloading,overspeed and location are realized as primary function in monitoring terminal.When the critical data is unable to upload owing to the bad GPRS network,SMS is used to instead of it.In this paper, programming of TCP data receiving server and image data displaying module of monitoring center were also completed.In view of the actual demand of monitoring and management of passenger transport industry,the structures and platform of a database system used in monitoring center were designed.Finally,we tested the system through the GPRS wireless network and Internet by sending image data and location information to remote monitoring center,at the same time analyzed the problems and proposed some improvements. |
