Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 as shown, The synchronous control system of heavy-duty locomotive signal There are master locomotives, intermediate locomotives, and slave locomotives, and ATP / ATO equipment is installed in the master locomotives, intermediate locomotives, and slave locomotives.

[0030] The ATP / ATO equipment installed on each locomotive is exactly the same, the purpose is to facilitate marshalling.

[0031] Each set of ATP / ATO equipment Including: ATP sub-box, ATO sub-box, wireless COM, DMI interface, vehicle control;

[0032] ATP plug-in box: 3 out of 2 security computers are used, and the 3 CPUs operate independently. When the calculation results of 2 or 3 CPUs are the same, the control logic is output. The ATP is responsible for the train's safety functions, including command generation, transmission, and application of emergency braking.

[0033] ATO...

Abstract

The invention discloses a synchronous control system and method for a heavy-duty locomotive. The synchronous control system is characterized in that an ATP (automatic train protection) plug-in box and an ATO (automatic train operation) plug-in box transfer a message to wireless COMs (component object model) by an Ethernet interface, transfer a message to a DMI (desktop management interface) by a 422 interface and are in hard wired connection with vehicle control. The synchronous control method comprises the following steps that: a ground management GSM-R (global system for mobile communications for railway) network sends an operation command to a master-control locomotive by a ground communication node; after the wireless COM of the master-control locomotive receives the command, the command is sent to the ATP / ATO equipment of the master-control locomotive; the ATP / ATO equipment calculates the traction force or the brake force of the master-control locomotive and a slave-control locomotive according to the line data and the current state of the locomotive, and outputs the command; the command is sent to the ground communication node by the wireless COM of the master-control locomotive; the communication node forwards the command to an intermediate locomotive and the slave-control locomotive according to an IP (internet protocol) address; after receiving the respective command, the wireless COM of the intermediate locomotive and the wireless COM of the slave-control locomotive forward the respective commands to the ATP / ATO equipment of the locomotive; after the synchronous control system receives the command, driving or brake control is carried out, and the locomotive marshaling control is guaranteed to be synchronous.

Description

Technical field [0001] The present invention involves a synchronization control system and method of heavy-duty locomotive signals, especially a synchronous control system and method based on a heavy-duty locomotive signal based on the ATP-ATO mode.This method is applied to the locomotive signal system of heavy -duty shipping trains to achieve synchronous control functions of the dynamic distribution of heavy cargo transport trains. Background technique [0002] my country ’s Daqin heavy -duty train line, as the first electrification line that specializes in heavy carrier trains in my country, is mainly for coal -specific coal trains to operate 5000 T to 10,000 T -levels. Its locomotive signal system is the introduction of the GE company Locotrol system. [0003] The basic principle is to rely on the 450MHz / 800MHz wireless communication link to remotely control multiple control locomotives, so that these locomotives are running like an overall train, which greatly reduces the hoo...
