Abstract: A low-power lamp identification card of multi-mode with over-voltage and over-current self-diagnosis function is designed to ensure the normal use time of miner’s lamp. Using single chip integrated design based on RFID and ZigBee technology, it can realize seamless upgrade from area to precise positioning. HFSS simulation software is used to optimize microstrip antenna, increase RF power amplifier, improve ZigBee accurate positioning and ranging accuracy and communication distance, and through the actual test optimization design, finally meet the field practical application.
