Abstract

The invention relates to an intelligent shunt circuit for a section track and a route type piecewise unlocking method, which solve the technical problems of frequently generating accidents caused by ill track shunt circuits in the prior art and avoiding potential safety hazards caused by three-point piecewise unlocking. The route type piecewise unlocking method comprises the following steps of: converting analog voltage pulse signals into digital voltage signals by a track circuit with the help of an A / D (analog / digital) conversion circuit; judging the occupancy condition of the section trackaccording to a curved line of the digital voltage signals; connecting a track circuit of a first section track and a track circuit of a second section track of a next-stage route in parallel; and respectively transmitting the collected voltage signals into a CPU1 (central processing unit 1) of the stage route. The route type piecewise unlocking method can effectively reflect the occupancy condition of the last section track of the stage route, and the routes can be better connected.

Description

technical field

[0001] The invention belongs to the field of railway train dispatching and train vehicle supervision and management, and specifically relates to an intelligent shunting method and unlocking method, in particular to a method for segmented track shunting based on a digital track circuit and an approach-based unlocking method segment by segment method. Background technique

[0002] There are many types of traditional track circuit systems, but they remain the same: mechanical track relays are used to judge whether the track is occupied by vehicles according to the pulse signal of the track voltage. The pulse signal is equivalent to an analog signal, for example, "1" represents car, use "0" to represent no car. The biggest problem of this method is the bad problem of the track circuit shunting caused by the rust between the rail and the wheel set of the vehicle. Due to the inability to ensure effective contact between the rail and the wheel set of the train, po...
