Abstract

The invention provides a method and a device for determining the state of an electropneumatic turnout switch machine. The method comprises the steps: acquiring the displacement parameter of a movable part in the electropneumatic turnout switch machine and the air pressure of an air cylinder of the electropneumatic turnout switch machine, wherein the movable part comprises at least one of an air cylinder piston, an indication rod and an action rod; and performing state detection according to the air pressure and the displacement parameters so as to determine whether the electropneumatic turnout switch machine breaks down or not, the position of the fault and the reason of the fault. According to the method, manual state detection of the electropneumatic turnout switch machine is not needed, the driving safety is improved, the state detection time is greatly shortened, and the state detection efficiency and the fault positioning accuracy of the electropneumatic turnout switch machine are improved.

Description

technical field [0001] The invention relates to the technology of an electropneumatic turnout point machine, in particular to a method and device for determining the state of an electropneumatic turnout point machine. Background technique [0002] Electropneumatic turnout switch machine is an important equipment used in rail transit signaling system. The electric idling turnout machine is controlled by electricity and uses compressed air as the power source. It has the characteristics of fast switching speed, large traction force and reliable locking. [0003] The operation safety of the electric-pneumatic switch machine directly affects the safety of transportation and operation. Therefore, in order to ensure safety, it is necessary to frequently detect the fault location and the cause of the fault during the operation of the electric-pneumatic switch machine. [0004] At present, the commonly used detection methods for electric-pneumatic turnout switch machines are manual...
