摘要
Abstract
As the performance of accelerometers and laser gyroscopes in navigation computers is easily affected by ambient temperature,it is necessary to accurately measure the ambient temperature.A multi-channel temperature acquisition system based on Kalman filtering is designed.The system uses PT1000 platinum resistance as the temperature sensor,completes signal conver-sion through conditioning circuit and A/D conversion circuit,and adopts a method combining improved Kalman algorithm with sub-section interpolation method to improve the system operation speed,reduces the error caused by hardware circuit interference,and improves the system acquisition accuracy.The test results show that the temperature detection of the system is in the range of-40℃～85℃,the system is stable,reliable and accurate,and the measurement error is±0.1℃,meeting the temperature measurement re-quirements of the system.关键词
