Claim 14:
15. The piezoelectric device online detection method according to claim 14, wherein the first measurement circuit is a first Resistor-Capacitor (RC) circuit; the second measurement circuit is a second Resistor-Capacitor (RC) circuit,
the controlling the first measurement circuit to detect the group of parallel sensors comprises: sampling an output of the first RC circuit by using the group of parallel sensors as a first capacitor in the first RC circuit, and detecting whether there is one or more damaged sensors in the group of parallel sensors according to a first sampling result; and
the controlling the second measurement circuit to detect the single sensor in the group of parallel sensors comprises: polling and detecting sensors in the group of parallel sensors by using the sensors in the group of parallel sensors as a second capacitor in the second RC circuit, sampling an output of the second RC circuit respectively, and determining the one or more damaged sensors according to a second sampling result.
