The change of foundation, line galloping and vibration will cause the change of the stress state of the tower. By monitoring the stress state of the tower, the accidents such as tower collapse and tower collapse can be forewarned in time. In view of the shortcomings of the existing tower stress monitoring device, such as inconvenient data collection and low measurement efficiency, this paper proposes a high-precision strain sensor chip and RFID technology-based strain sensor to monitor the tower strain. According to the characteristics of strain sensor collection unit and RFID technology, a low-power strain sensor for real-time monitoring of strain data of transmission towers was designed. It can be read and recorded by hand-held reader, which improves the collection efficiency of strain information of towers and reduces the manual operation. In view of the shortage of energy supply of transmission line sensors, the power consumption design extends the effective working time of the sensor.
