摘要:惯导系统是精确制导武器中不可或缺的重要组成部分。在战术级或小型化产品上通常要对每个产品进行单独温度误差补偿等措施以抑制环境温度的影响。因此在生产线上,需要对光纤陀螺惯导系统的测温部件进行专门的标定,通过调整环节使其与基准温度源的误差保持在一定的要求范围内。通过对测温电路的分析,提出来一种测温电路调试方法,对三温度点测试法得到的测试数据进行线性拟合,结合调试电阻对拟合曲线的斜率和截距的影响关系调整调试电阻的大小,即可快速完成测温电路的调试。实际测试证明该方法是可行的。

Abstract: Inertial navigation system is an indispensable part of precision guided weapons. In a tactical or miniaturized product, individual temperature error compensation and other measures are usually used to suppress the influence of ambient temperature. Therefore, it is necessary in the production lines to calibrate the temperature measuring components of fiber optic gyroscope inertial navigation system and keep the error with the reference temperature source within a certain range through the adjustment. Based on the analysis of temperature measuring circuit, a debugging method is put forward for the rapid adjustment of the temperature measuring circuit, which adopts three-temperature-point test method to measure temperatures, performs the linear fitting of the test data, and adjusts the debug resistance combined with the influence of the debugging resistance on the slope and intercept of the fitted curve. The test results show that the method is feasible.
Key words: inertial navigation system; temperature measurement circuit; rapid debugging
