The embodiment of the invention provides a turnout friction current automatic setting method and device. The method comprises the steps: obtaining a friction current curve when a turnout is in an overhauled state is obtained; solving a first-order derivative and a second-order derivative of the friction current curve when the turnout is in the second stage to obtain a turnout friction current parameter change value in the second stage; based on the friction current curve, obtaining turnout friction current mean values of the first stage and the third stage; and if the turnout friction currentparameter change value of the second stage is within a first preset current change threshold range and the difference value between the turnout friction current mean value of the first stage and the turnout friction current mean value of the third stage is within a second preset current change threshold range, storing a friction current curve, and scoring the friction current curve. According to the embodiment of the invention, the optimal friction current curve is analyzed based on the change conditions of the current curves of the turnout in different stages, so that the workload of maintenance personnel is reduced, and meanwhile, manual errors can be effectively avoided.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and device for automatically setting the friction current of a turnout. Background technique [0002] In recent years, with the continuous development of intelligent operation and maintenance of turnouts, the dependence on the friction current value of turnouts is getting higher and higher. Errors in friction current settings or setting errors directly affect the judgment and prediction of turnout failures, and wrong judgments also It will bring more false alarms to the operation and maintenance personnel and affect the normal work arrangement. [0003] For the friction current configuration technology of the turnout, the current methods are mainly carried out in the following ways: 1) By manually simulating the blockage fault of the turnout, analyzing the friction current parameters of the turnout, and manually entering the parameter value; 2) By manually simulatin...
