Abstract

The invention discloses a method, a device and a system for determining the excitation frequency. The method comprises the steps that pipeline information of a to-be-detected pipeline and environment information of the environment where the to-be-detected pipeline is located are acquired; and the pipeline information and the environment information are processed based on a preset model, and the excitation frequency of the to-be-detected pipeline is obtained, wherein the preset model is a model constructed based on the relation among the historical pipeline information, the historical environment information and the historical excitation frequency. The technical problem that the excitation frequency cannot be accurately determined in the prior art is solved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a method, device and system for determining an excitation frequency. Background technique [0002] In the prior art, workers can detect the excitation of the electromagnetic coil of the strain gauge to cause the steel string to resonate, and then calculate the tension on the steel string according to the frequency signal when the steel string resonates. [0003] In the prior art, the following methods are usually used to make the steel string resonate: [0004] (1) Sweep frequency excitation method. In the sweep frequency excitation method, the steel string is excited by a series of continuously changing frequency signals output by the strain gauge. When the frequency signal is close to the natural frequency of the steel string, the steel string can quickly reach the resonance state and realize reliable vibration. After the vibrating steel string vibrates, the frequency of the ...
