Abstract

The invention relates to an anti-interference physical quantity acquisition system, method, and device and computer equipment. The system comprises a branching module, a delay module, a rate-of-changedetecting module, a triggering module and an input switching module. The input terminal of the delay module is connected to a first output terminal of the branching module; the output terminal of thedelay module is connected to a first input terminal of the input switching module; the input terminal of the rate-of-change detecting module is connected with a second output terminal of the branching module; the output terminal of the rate-of-change detecting module is connected with the input terminal of the triggering module; and the output terminal of the triggering module is connected with aswitching signal terminal of the input switching module. According to the system, when a change rate of the other path of physical quantity is detected to exceed a preset change rate, the one path ofphysical quantity after delay processing is blocked, so that effective blocking process of the interference signal is realized before usage of the physical quantity logic and thus the anti-interference processing efficiency of the physical quantity is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a physical quantity anti-interference acquisition system, method, device and computer equipment. Background technique [0002] In the field of industrial technology, in the process of measuring physical quantities (physical quantities with proportional or inertial link characteristics), such as the rotational speed of rotating machinery, due to the complexity of on-site electromagnetic interference, the measurement of physical quantities inevitably has interference problems. [0003] In order to solve the above technical problems, some anti-interference measures are usually taken at the measurement end and in the signal transmission links, such as shielding, long-distance DC current signal transmission, etc., to process the interference signals generated in the process of measuring physical quantities. However, in the processing There will also be a sudden change in the...
