Current detection circuit and current detection method

Abstract

The invention discloses a current detection circuit and a current detection method. The current detection circuit comprises a detection module, a signal processing module, a first control module, a driving module and a second control module, the detection module detects the running current of the to-be-detected equipment at the first gear and generates a first current signal; the signal processingmodule performs denoising processing and signal amplification processing on the first current signal to obtain a second current signal; the first control module receives and judges whether the amplitude of the second current signal is in the detection range of the current detection circuit or not, and if the amplitude of the second current signal is not in the detection range of the current detection circuit, the first control module outputs a gear switching signal; the driving unit generates a gear driving signal according to the gear switching signal and outputs the gear driving signal to the second control module, and the second control module switches the gear of the detection module according to the gear driving signal so that the detection module detects the running current of the to-be-detected equipment again under the switched gear ; and the compatibility of the current detection circuit is high.
