<p>Disclosed is a measurement method for an aviation-specific displacement sensor. The method comprises the steps of: (1) establishing a measurement circuit: forming a magnetic induction sensor with an internal resistor r and an inductor L; (2) establishing a lookup table: using an ADC to separate inductor discharge voltage values U1 and U2 corresponding to two fixed delay times T1 and T2, and obtaining a discharge voltage equation U1 (T1, R, r, L) and U2 (T2, R, r, L) of an r-L circuit; (3) compressing the lookup table, and using the compressed lookup table to measure a displacement sensor. The measurement method of the present invention ensures that the system operates within the temperature range of military standards, at the same time increases the stability, reliability and real-time performance of system measurement, has no floating-point operations, and omits CPU or MCU hardware resources.</p> |
