Method for resolving corresponding inductance value of multichannel proximity sensor

The invention discloses a method for resolving a corresponding inductance value of a multichannel proximity sensor, and aiming at solving the problem of long digital resolving time of the proximity sensor in a multichannel state. The goal of the method is achieved by the following technical scheme that in the process of resolving the corresponding inductance value of the multichannel proximity sensor, each path of signal conditioning circuit receives signals from a corresponding connected proximity sensor; the signals are processed to be in a digital signal state through filtering and amplification; through alternating current response signals generated by the proximity sensor, different channels of sensor signals are transmitted into an A/D sampling circuit by switching a multiway switch;a channel switching and control circuit performs digitization processing on analog signals transmitted from the multiway switch at control time sequences of a CPU; an A/D conversion circuit outputs binary numerical values co
