Ultra-high frequency RFID vehicle fixed-point parking method with automatic calibration of transmission power. The main control module adjusts the transmission power to the maximum power value for reading work. If no electronic tag is detected within the set time threshold range, the power calibration work is stopped. If the RFID reader can read the content of the electronic tag, the transmission power is gradually reduced according to the set fixed power interval value. After each reduction of the transmission power, the electronic tag is read. When the tag information cannot be read after reducing the transmission power, the corresponding transmission power is recorded, and this is the calibrated power value at this time. After the transmission power is calibrated, every time the user parks the vehicle, the RFID reading and writing module reads the tag with the calibrated power value. If the tag can be read, it means that the corresponding vehicle has been parked in the designated position. If the tag cannot be read, it means that the vehicle has not been parked in the designated position. The present invention provides an efficient and simple method for automatic calibration of transmission power, improving the usability and accuracy of the product.
