[0002] The current RFID technology temperature sensor acquisition method is mostly fixed frequency, fixed power. In practical applications, due to the different installation positions and angles of the RFID radio frequency antenna, as well as the different positions and directions of the internal sensing IC (integrated circuit) of the temperature sensor, the RFID radio frequency antenna often fails to receive part of the temperature sensor data, or even sometimes completely fails to receive the temperature sensor data, resulting in incomplete or missing data, making it difficult for maintenance personnel to accurately determine the status of the cable head, increasing the difficulty and cost of maintenance, and thus making the entire cable head temperature monitoring system ineffective, unable to detect abnormal temperature of the cable head in time, thereby increasing safety hazards.
