Abstract：To ensure the accuracy of non-invasive parachute lifting belt tension sensor in high altitude environments， this paper proposes a temperaturecompensation algorithm based ona combination of cubic spline interpolation and least squares method for temperature compensation of the tension sensor， with temperature compensation ranging -40°C to . The temperature compensation experiment was conducted using experimental devices such as a constant temperature boxanda standard tensile machine.The experimental results show that the designed temperature compensation algorithmcan effectively solvethe problems of zero drift and sensitivity drift caused bychanges in the working environment temperature of the sensor.
