Abstract: In view of the requirements of control center grasping the precise state information of the running vehicles in open-pit,this truck monitoring and scheduling system which costs low and covers a wide range for the mine has been developed.The terminal of system is installed on the vehicles.Using arm9 embedded platform with high quality of GPS module and GPRS module to complete the collection and transmission of vehicle information,functions of each module are researched and developed in the linux system.The running results show that the system is accurate,stable and reliable in data acquisition and transmission.It’s useful for the scheduling and decision-making of the relevant staff,by directly showing the running vehicles with the GIS application.
