Embodiment Construction

[0022] exist figure 1 and figure 2 Among them, 1 is the rail, 2 is the GXDM-H / D type anti-interference magnetic sensor, and 3 is the rail clip. The magnetic sensor 2 is 30mm-35mm away from the rail surface, and is fixed on the inner side of the rail 1 by the rail clip 3. The truck wheel center distance is 1.88 meters, it is also the magnetic sensor C 1 、C 2 installation center distance.

[0023] currently in use image 3 To illustrate the principle of distinguishing passenger and freight cars: two wheel sensors for detecting the arrival of train wheels are installed on a rail. Their installation center distance is equal to the center distance of a set of truck wheels. When the wheels of a truck pass by, there is always a moment when two pulses occur at the same time, but for a passenger car, the center distance of a group of wheels is greater than the installation center distance of the two wheel sensors, so there is no moment when two pulses occur at the same time. The...

Abstract

An automatic train type recognition system for distinquishing passenger train from goods train is composed of 4 magnetic sensors, a signal processing circuit and a programmable controller connected in sequence. The 4 magnetic sensors have one pair of magnetic sensor installed to one rail and having a central distance equal to that of two pairs of wheels, one magnetic sensor for shielding locomotive and generating a signal for beginning recognization, and another magnetic sensor for sensing arrival of locomotive, ending the recognition and reading the result. It is based on the reality that the spacing between two groups of wheels of the passenger train is greater than that of goods train.

Description

technical field [0001] The invention relates to a method and system for identifying railway passenger and freight cars by a wheel spacing method and belongs to the technical field of automatic identification of railway passenger and freight cars. Background technique [0002] 60 Co railway wagon online inspection system is an efficient, reliable and powerful system for combating smuggling developed to adapt to the characteristics of border railway port transportation inspection. But at some customs railway checkpoints, passenger and freight cars share a track. But only trucks need to be checked, so an online inspection device that can automatically identify passenger and trucks is needed. [0003] Also do not have the device that carries out automatic identification specially at the van. Existing automatic identification devices for railway vehicles all identify train vehicle types and vehicle numbers. Be 92210541 as application number, authorized announcement number be ...
