Coal Yard Vehicle Management Cloud Platform Based on DGPS and 4G Network

A cloud platform system for coalfield vehicle management based on DGPS and 4G network is designed. Take STM32F407 as the main processor, the software system of multifunctional terminal has been designed and implemented on the basis of DGPS and 4G network. Java technology is utilized to develop remote software system of vehicle management platform. Multifunctional terminal can acquire DGPS information in real time, realize vehicle information query and local call functions. The remote vehicle management platform can supervise the position and condition of vehicles in coal yard and transmit the information to each terminal. The test results show that the system is stable, the positioning accuracy is high, and the network transmission capacity is strong, which can meet the requirements of complex vehicle management in coal storage yard.
