Control method and control device for filtering time constant, computer device and storage medium

Abstract

The embodiment of the invention discloses a control method and a control device for a filtering time constant, a computer device and a storage medium, wherein the filtering time constant are dynamically adjusted and the detection defect caused by fast detection or slow detection is avoided. The embodiment of the method comprises the following steps: acquiring an input detection value; when the detection value is different from a first preset threshold value, determining a first difference value between the detection value and the first preset threshold value; and determining a filtering time constant corresponding to the detection value according to the first difference value.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a control method and device for a filter time constant, a computer device, and a storage medium. Background technique [0002] In general, amplitude detection can use fixed filter time rising and falling edge detection. Wherein, the comparison between the detection time and the filtering time constant can be used to detect whether the amplitude is abnormal. For example, when the detection time exceeds the filtering time constant, the amplitude is considered abnormal. [0003] However, when the input amplitude, that is, the detection value, exceeds the threshold by a large amount, the speed of detection with a fixed filter time constant is relatively slow, and when the input detection value is critical to the threshold, the speed of detection with a fixed filter time constant is relatively fast. It can be seen that the amplitude detection based on a fixed filter time constant i...
