Current curve fitting method and device, equipment and storage medium

Abstract

The embodiment of the invention provides a current curve fitting method, device and equipment and a storage medium. The method comprises the steps of collecting discrete three-phase current data when a turnout acts; performing difference on every two of the three-phase current data in the preset time range to obtain a difference value, and performing current curve fitting according to the difference value; when the three groups of difference values are all smaller than a threshold value, performing current curve fitting after fusing the three-phase current data of the corresponding part; when two groups of difference values are greater than a threshold value, fusing two phases of current data corresponding to the difference values less than the threshold value and then carrying out current curve fitting, and independently carrying out current curve fitting on the other phase of current data; and when the three groups of difference values are all greater than a threshold value, current curve fitting is respectively carried out on the three-phase current data of the corresponding part. The turnout fault features are reserved, it is also guaranteed that a curve is smoother and more attractive, and the operation safety of equipment is effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of rail transit, and in particular to the field of switch operation current fitting. Background technique [0002] With the continuous development of my country's rail transit, higher requirements are put forward for the safe operation of railway signal equipment. As the main equipment on the trackside of the signal, the turnout is of great significance to ensure the safety of traffic. On the basis of real-time grasp of the operation status and various data of the turnout, the method of identifying and diagnosing the fault of the turnout is studied to provide specific help for the maintenance personnel. , to ensure real-time alarm of turnout failure is very meaningful. However, in the existing methods for monitoring the switch current, there are mainly the following disadvantages: (1) The current data is limited by the bandwidth and micro-period, and discrete points are used to collect the current ...

However, in the existing methods for monitoring the switch current, there are mainly the following disadvantages: (1) The current data is limited by the bandwidth and micro-period, and discrete points are used to collect the current data

(2) Discrete data is easy to miss the instantaneous current value and lose current characteristics

(3) The drawing of the current curve produces jumps and is not beautiful
