Card Reading Substation of Mine Flameproof and Intrinsic Safety Based on STM32
Abstract
To meet the requirements of unique detection of coal mine personnel management system and working state detection for identification card, a card reading substation of flameproof and intrinsically safe is designed based on STM32f103RCT6. The hardware circuits such as power supply, main control unit, display module and power amplifier are designed. Meanwhile, the embedded software of uc/os-III is designed, and the processing efficiency of the microprocessor has been improved by multi-task scheduling. The data can be sent and received through the USART serial ports of the microprocessor. Finally, the identification of identification cards, card number display and voice broadcast are realized.
