Abstract

The invention discloses a signal interference source determining method and device. The method includes the steps that a point to be tested is determined, and the point to be tested is a device node on an interfered signal transmission path; a plurality of electric field intensity values and a plurality of magnetic field intensity values are acquired at the point to be tested, wherein the electric field intensity values and the magnetic field intensity values respectively correspond to preset frequencies; the target electric field intensity value in the multiple electric field intensity values at the point to be tested and the target magnetic field intensity value in the multiple magnetic field intensity values at the point to be tested are determined; the preset frequency corresponding to the target electric field intensity value and the target magnetic field intensity value is determined as the target frequency; according to the preset corresponding relation between the target frequency and an interference source, the interference source is determined. Through the signal interference source determining method and device, the interference source can be quantitatively measured and accurately determined.

Description

technical field [0001] The present invention relates to the technical field of decentralized control of generator sets, and more specifically, to a method and device for determining an interference source. Background technique [0002] In the generator set production site, a DCS (Distributed Control System, decentralized control) system is arranged. The monitoring equipment installed on the field production equipment, such as sensors, sends the collected signal to the DCS system through the cable, and the DCS system receives the signal, and realizes the monitoring and control of the various production equipment according to the signal. Wherein, sending the signal to the DCS system needs to pass through some device nodes such as junction boxes, cable trays, photoelectric converters and the like. [0003] As we all know, on-site production equipment or other electronic equipment such as welding machines and electrostatic precipitators will generate electromagnetic radiation d...
