AI Technical Summary
In existing technologies for strain monitoring of transmission towers, the measurement circuit of metal foil resistance strain gauges suffers from problems such as manufacturing errors in the bridge resistor and insufficient filtering of the strain measurement signal during engineering, resulting in low measurement accuracy and high power consumption of the sensor node.
The traditional strain measurement circuit of the Wheatstone bridge is optimized by integer linear programming, and the strain signal is filtered by first-order Kalman digital filtering. A low-power strategy is designed to optimize the strain measurement method of the sensor node.
It effectively reduces strain measurement error, improves measurement accuracy, and reduces power consumption of sensor nodes, making it suitable for node strain monitoring of transmission towers.
