Video security protection system and implementation method of locomotive platform crossing based on 4g network

Abstract

The invention relates to a 4G network-based locomotive crossing video security protection system and its implementation method. The system includes a security protection mobile terminal, a cloud server, a locomotive platform display terminal, a locomotive platform host, and a power supply. The locomotive platform display terminal is connected to the locomotive platform host. , the locomotive platform host and the safety protection mobile terminal are connected through the host's built-in 4G network, and the safety protection mobile terminal and the cloud server are connected through the host's built-in 4G network; during the train operation, the safety protection mobile terminal displays the video image of the designated crossing, and makes pedestrians, Animals and other objects are detected, and the driver will be notified by voice alarm after abnormal detection, and the current location map information will be displayed in real time. The system implements a visual wireless driving safety protection system, which can grasp the situation of the crossing ahead, which is beneficial to make judgments and make driving operations in advance, and prevent accidents such as collisions caused by abnormal crossings.

Description

technical field [0001] The invention relates to the field of railway running safety protection, in particular to a 4G network-based locomotive platform crossing video safety protection system and an implementation method. Background technique [0002] With the development of high-speed and high-intensity railway transportation business, railway communication has an increasing demand for high-quality wireless coverage, communication performance under high-speed operation, scalability and compatibility, and the evolution and application of new technologies are inevitable. At present, the train dispatching and 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the GSM-R communication system is relatively mature, GSM-R is a narrowband system, and the technology itself is outdated. After the completion of a network, only voice communication can be used. , can not meet the needs of diversity, in addition, the GSM-R system is complex, the ...

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.
