Locomotive station crossing video safety protection system based on 4G network and implementation method

Abstract

The invention relates to a locomotive station crossing video safety protection system based on a 4G network and an implementation method, the system comprises a safety protection mobile terminal, a cloud server, a locomotive station display terminal, a locomotive station host and a power supply, the locomotive station display terminal is connected with the locomotive station host, and the locomotive station host is connected with the safety protection mobile terminal through a host built-in 4G network. The security protection mobile terminal is connected with the cloud server through a 4G network built in the host; in the train running process, the safety protection mobile terminal displays video images of a specified crossing and detects objects such as pedestrians and animals, a driver is informed through voice alarm after abnormity is detected, and meanwhile current position map information is displayed in real time. According to the visual wireless driving safety protection system, the situation of the crossing ahead can be mastered, judgment and driving operation can be made in advance, and accidents such as collision caused by abnormity of the crossing are prevented.

Description

technical field [0001] The invention relates to the field of railway traffic safety protection, in particular to a 4G network-based locomotive crossing video safety protection system and an implementation method. Background technique [0002] With the development of high-speed and high-intensity railway transportation business, the demand for high-quality wireless coverage, communication performance under high-speed operation, scalability, and compatibility in railway communication is increasing, and the evolution and application of new technologies have become inevitable. At present, the train dispatching command system of the National Railway mainly adopts the GSM-R communication system. Although the GSM-R communication system is relatively mature, GSM-R is a narrowband system, and the technology itself has fallen behind. After a network is completed, it can only be based on voice communication. , unable to meet the needs of diversity. In addition, the GSM-R system is comp...

Problems solved by technology

At present, the train dispatching command system of the National Railway mainly adopts the GSM-R communication system. Although the GSM-R communication system is relatively mature, GSM-R is a narrowband system, and the technology itself has fallen behind. After a network is completed, it can only be based on voice communication. , unable to meet the needs of diversity. In addition, the GSM-R system is complex, the investment cost is high, and it is also subject to the frequency resource policy. In general, the GSM-R system is not developmental, forward-looking, and feasible for local railways, and There are also the following problems in the application field:

[0004] The second is that there are many level crossings along the railway line, which are prone to casualties of people and vehicles outside the road. The "Technical Regulations" require that the braking distance of trains with a speed of less than 120 kilometers per hour should not be less than 800 meters, and the long-distance view is limited. , especially in the case of severe weather such as rain, snow, wind and sand, in the event of an emergency, it is very easy to make a misjudgment, and the consequences are disastrous

[0005] Third, at present, some of the existing traffic sections adopt the dual-machine double-connection traction mode, which produces a large amount of knuckle work and affects the efficiency of driving organization. Therefore, it is planned to promote the dual-machine supplementary traction mode. The current communication method cannot meet the requirements of the dual-machine supplementary traction mode. Communication requirements, it is necessary to have a voice and video dual-mode communication system to solve the above problems

In the event of card breaking or other emergencies, only a warning will be issued, but no timely interception will be made

Publication No. CN108639111A "Crossing Control Alarm System" patent application, in order to ensure driving safety, the crossing control alarm system detects through sensors that there are pedestrians passing through when the train is about to pass the crossing, and sends the alarm information to the dispatching center, which then sends it to the train driver , the efficiency of this method is low, which is not conducive to the train driver to make a safety judgment in real time

Publication No. CN111818297A "A Railway Locomotive Approaching Crossing Video Automatic Access System" patent application, obtain the current locomotive position through the locomotive's own on-board carrier phase satellite positioning module, and use the route data to obtain the pre-configured location through the station computer interlocking system The moving direction of the locomotive is close to the video signal of the crossing; according to the speed of the locomotive, the video of the crossing in front is displayed in a timely manner. This method only displays the video of the crossing and does not give an alarm to the danger, and if the distance between the two crossings is relatively close, the driver needs to stare at it for a long time The screen is easy to cause visual fatigue for the driver, and it is impossible to find the danger at the first time. Secondly, the driver cannot independently select a certain crossing video to view, nor can he view any running information of the locomotive, which has great limitations.

In short, whether the driving time of the locomotive is accurately communicated, whether the crossing interception facilities are activated correctly, whether there are obstacles, pedestrians or vehicles in the driving safety area, and a series of problems may affect driving safety and even endanger personal safety.
