Abstract

The invention provides a control method for electric switch machines. The method comprises the following steps that: a detection control unit controls a motor to rotate according to a received control signal; the rotating motor drives an operating rod to make a rectilinear motion; and the detection control unit detects the position of the operating rod through a position sensor, and when detecting that the operating rod moves to a preset position, the detection control unit controls the motor to stop rotating. Compared with the prior art, the technical scheme of the invention has the following advantages: the existing finalization of a control turnout combined circuit is not required to be damaged and modified; and the position information is detected by using the position sensor, therefore, the reliability is high, and a maintenance-free effect can be basically realized.

Description

technical field

[0001] The invention is applicable to the field of electric switch machine control, and in particular relates to an electric switch machine control method. Background technique

[0002] The electric switch machine is a device used to change the opening direction of the railway line and lock the turnout, and the switch machine is the core and main body of the switch device. In particular, the electric switch machine for teaching sand table is an electric device used to control the turnout and change the opening direction of the turnout for simulating the actual operation process of the train. Because in the teaching of various related majors in railway colleges and universities, it is often necessary to simulate the actual application process of the railway site, and it is necessary to combine the teaching sand table for actual operation training, and the steering of the model turnout is required in the operation training. In the traditional electric switch m...
