Embodiment 1

[0051] A possible implementation of the train remote observation system is as figure 2 As shown, the cameras along the railway are arranged at intervals, and adjacent cameras can achieve seamless coverage of images along the railway. The cameras can use analog camera frequency division to obtain signals, or they can use digital interface cameras such as Gigabit Ethernet or Camelink. All cameras The collected image signal is transmitted to the remote observation server. The image transmission can be wired or 3G, 4G and other wireless networks. The remote observation server saves the GPS coordinate positions of all cameras and the calibration parameters of the cameras in advance. The trains running on the line will pass The vehicle-mounted intelligent terminal periodically (for example, 5s) sends the train's own position (longitude and latitude obtained by GPS or line kilometer mark position obtained by other positioning devices) to the remote observation server. After the remote ...

Embodiment 2

[0053] A possible railway line construction worker protection alarm system scheme is as follows: workers on the line can use tablet computers or smart phones as the smart terminal of the alarm system. The handheld smart terminal works similarly to the vehicle-mounted smart terminal. The handheld smart terminal will The GPS location obtained by itself is sent to the remote observation server. After the remote observation server receives the location of the device, it will be in a certain area near the device (the size of the area can be set by yourself, generally according to the vehicle speed and the time required for the evacuation of the construction site Comprehensive consideration) The location of other equipment is sent to the terminal. Other equipment may represent the train or other construction personnel. The display can be distinguished by setting different signs. For trains passing nearby, the image of the passing position of the train will be sent to the smart termina...

Abstract

The invention provides a train early-warning system and a train early-warning method. The train early-warning system comprises foreign matter detection sensors, a foreign matter detection processing unit, an outlook server and intelligent terminals, wherein the sensors are installed along a railway or on a preset segment to collect environmental information, and the processing unit receives the environmental information collected by the sensors and judges whether foreign matter exists or nor; when no foreign matter exists, the environmental information is sent to the outlook server, and otherwise, a detection result is generated, the foreign matter is marked so that a foreign matter alarm can be formed and sent to the outlook server; the outlook server receives location and motion information, manual alarm information and active request information from some intelligent terminal, sets an alarm range and an outlook range related to the location, determines the corresponding sensor and sends the environmental information within the outlook range or the foreign matter alarm result within the alarm range and the locations of the other intelligent terminals to the intelligent terminal; the intelligent terminal generates information of the locations of the intelligent terminal and sends the information to the outlook server; when no foreign matter is detected within the alarm range, the intelligent terminal receives and displays the environmental information within the outlook range, and otherwise the intelligent terminal receives the environmental information within the outlook range and gives out an alarm.

Description

Technical field [0001] The present invention belongs to the field of railway operation safety. In particular, it relates to a railway remote observation and train approach early warning system, and more specifically, to a train early warning system and a train early warning method. Background technique [0002] Current train operation control systems are based on signals provided by ground facilities such as track circuits, ground transponders, and trackside cables for train control. Once these devices fail due to external factors or their own factors, it is very easy to cause vicious accidents such as rear-end collision. Even in the plains, the driver’s vision of the eyes is very limited. Even if factors affecting driving safety are discovered, it is too late to take measures. [0003] At present, in rail transit at home and abroad, cameras or lidars are used to implement safety monitoring at key locations such as crossings and stations. For example: Yu Ge and others from the In...
