In view of the problems such as inaccurate real-time positioning, misreading, lost track and inability to count the number of passengers in the compartment at present, which are affected by faster vehicle speed and metal shielding in the compartment, when personnel in underground coal mine are traveling on mining vehicles, we designed a vehicle mounted card reader based on UWB accurate positioning technology and low-frequency wake-up technology. The vehicle mounted card reader uses the ARM control chip STM32F413, UWB communication transceiver chip DW1000 and low frequency wake-up transmitter EM4095 as the core. By the method of triggering UWB communication channel switching through low-frequency wake-up, the accurate positioning and quantity statistics of the personnel in the mining vehicle compartment are realized. The test results show that the vehicle mounted card reader can accurately distinguish the personnel inside and outside the vehicle, effectively solve the problems such as missing identification and inaccurate positioning caused by the metal shielding of the compartment, and the maximum dynamic positioning error is not more than 7.3 meters. These can meet the application requirements of coal mines. It is of great significance to carry out intelligent vehicle appointment and dispatching business in underground coal mine and to promote intelligent traffic construction in underground coal mine.
