Embodiment Construction

[0024] Referring to the accompanying drawings, it is an intelligent shunting method for a section track. The above method is to convert the pressure deformation of the section track into an analog electrical signal and send it to a management The CPU of the program, after the CPU calculates and processes, controls the relay of the signal machine through the management circuit, and displays the occupancy of the section track. The specific steps of the above method include:

[0025] ①. The track circuit uses the A / D conversion circuit to convert the above-mentioned analog voltage pulse signal into a digital voltage signal in real time, and judge the current occupancy of the section track according to the derivative change rate of the curve point of the digital voltage signal;

[0026] ②. Set the branch level for the digital analog signal of the section voltage signal collected during the train rail pressing process, and store it in the supporting storage unit in real time, and co...

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 track according 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...
