China's first intelligent heavy haul train
National heavyweight, China's first intelligent driving heavy-duty train running
can you imagine a heavy-duty 10000 ton train driving automatically?
it is reported that China's first intelligent driving "3 + 0" ten thousand ton heavy-duty train opened at Shenmu North Station of Shenshuo railway recently. The first train 7033 consists of 108 carriages, with a total length of 1530 meters and a load of over ten thousand tons of coal. This is a new breakthrough in the development history of China's heavy haul railway technology, marking that China has mastered the core technology in the field of intelligent heavy haul train control, marking that China's heavy haul railway development has entered a new stage. The
Shenshuo railway is a large channel for the transportation of coal from the west to the East, an artery for the transportation of blood to the East, and a national class I electrified heavy-duty railway. As a heavy-duty railway, Shenshuo line has a minimum turning radius of 400m and a maximum gradient of 12 ‰. It can be said that the slope is steep and the curve is sharp. There are many bridges, tunnels and culverts along the line, which pose a great challenge to the safe and stable operation of heavy-duty trains. The equipment loss is serious, and a large number of drivers and passengers are required to be employed. The labor cost is very high.
in order to solve the difficulties and ensure the driving safety, Shenshuo Railway Branch of national energy group, CRRC Zhuzhou office and CRRC Zhuji plant jointly tackle the four major problems of geography, line, climate and long and steep slope, and successfully start the intelligent driving heavy-duty train of Shenshuo railway. This train is the first of many heavy-duty train technologies in China: the first to realize the automatic driving of heavy-duty 10000 ton train; the first to apply the operator network in heavy-duty railway; the first to realize the automatic train coupler coupling, uncoupling, wireless reconnection marshalling; the first to set up foreign matter intrusion detection system in heavy-duty railway. How automatic and intelligent is the train? It is understood that the locomotive intelligent driving system takes "perception, decision-making and execution" as the design idea to realize the automatic control of the whole process of heavy-duty train operation, including automatic wake-up, automatic servicing, automatic out of section, automatic coupling, automatic departure, automatic through test, automatic phase separation, automatic operation, automatic parking, automatic in section, automatic shunting and automatic rest according to the scheduling plan Sleep and other functions. After the dispatcher issues the locomotive operation instruction, the locomotive automatically accepts the order, automatically wakes up, automatically raises the pantograph to close the main and auxiliary machines, enters the automatic traction test state, recovers the signal after the test is completed, analyzes the outbound and outbound according to the order, and automatically connects after arriving at the station, then the locomotive enters the operation test link, according to the station signal, the train departs, according to the The line and climate conditions, including whether there are obstacles in the front line, as well as data and scenarios such as wind, snow and lightning, are automatically detected to ensure safe operation.
from this, we can see the spirit of Chinese engineers to face the difficulties. Not only the high-speed railway, but also the freight train in China should be automated. China Railway is developing every day and brings us surprises every day. This is the result of unremitting efforts, hard work and tenacious struggle of generations of railway people. We have reason to be proud of them.
