Train navigation monitoring early warning system and early warning method thereof

Abstract

The invention relates to a train navigation monitoring early warning system which comprises a navigation monitoring early warning module, a power supply module and a monitoring center, wherein the navigation monitoring early warning module comprises an inertia navigation module, a wireless communication module and an image processing module; the power supply module is connected with the navigation monitoring early warning module; the monitoring center comprises a server and a wireless communication module, and the server is connected with the navigation monitoring early warning module by a wireless network. The early warning method comprises the following steps: the navigation monitoring early warning module measuring the acceleration of a train in real time by adopting an accelerometer, and collecting the attitude information of the train in running by adopting a gyroscope; adopting an inertial navigation algorithm to calculate the collected acceleration data and the attitude information in a central processor to obtain the train running speed and the position information of the train; and adopting the image processing module to collect the situation of surrounding objects of the train in running, so as to judge whether a barrier exists in front of the train. The train navigation monitoring early warning system can effectively prevent the occurrence of abnormal events such as train derailment, collision or the like.

Description

technical field [0001] The invention relates to a navigation safety early warning system, in particular to a train navigation monitoring and early warning system. Background technique [0002] With the development of railways, the speed is getting higher and higher, and the problems caused by high-speed driving are gradually exposed. In recent years, many problems caused by high-speed trains have occurred, which have caused huge damage to the lives of the people and the property of the country. Losses, for example: at about 2 am on May 23, 2010, passenger train K859 from Shanghai to Guilin derailed. This accident has caused 19 deaths, 11 serious injuries and 60 minor injuries. 2,800 people were evacuated. Many passengers; at 20:27 on July 23, 2011, when the D301 train from Beijing to Fuzhou was traveling to the Shuangyu section of Wenzhou City, it collided with the D3115 train from Hangzhou to Fuzhou, causing two carriages of the D3115 train to fall Under the bridge, anothe...
