Embodiment 1

[0062] A special domain belt network traffic communication navigation monitoring and early warning device, its overall structure is as follows figure 1As shown, the device includes LTE private network communication base station, GPS / Beidou dual-mode positioning ground-based enhanced reference station, multi-functional vehicle multimedia information terminal, sparse distributed monitoring and LED induction early warning equipment, traffic early warning mobile phone APP, tracking main aerial photography system , micro-meteorological collection equipment, distributed automatic snow defrosting device and background control and data center; LTE private network communication base station, GPS / Beidou dual-mode positioning ground-based enhanced reference base station, sparse distributed monitoring and LED induction early warning equipment, micro-weather collection The equipment and the distributed automatic deicing and frosting device respectively communicate with the data center throu...

Embodiment 2

[0089] A special-domain strip private network traffic communication navigation monitoring and early warning device, its overall structure is as described in Embodiment 1, the difference is that, further, the LTE private network communication base station is located beside the expressway, and the LTE private network The signal coverage radius of the network communication base station is 10km. Correspondingly, the distance between two adjacent LTE private network communication base stations is less than or equal to 20KM. The LTE private network communication base station provides a data transmission rate of uplink 30M and downlink 50M.

Embodiment 3

[0091] A special-domain strip private network traffic communication navigation monitoring and early warning device, its overall structure is as described in Embodiment 1, the difference is that, further, the GPS / Beidou dual-mode positioning ground-based enhanced reference base station is located in the expressway service area , the distance between adjacent GPS / Beidou dual-mode positioning ground-based augmented reference stations is less than or equal to 60km.

Abstract

The invention relates to a special-region band-type private network transportation communication navigation monitoring and warning device. The device comprises an LTE (long term evolution) private network communication base station, a GPS (global positioning system)/Beidou dual-mode positioning foundation reinforced reference station, a multifunctional vehicle-mounted multimedia information terminal, a sparse distributed monitoring and LED induced warning device, a traffic warning mobile phone APP (application), a tracking body aerial photography system, a microclimate acquisition device, a distributed automatic snow and frost removing device and a background control and data center. By the device, highway all-section non-blind-area high-speed wireless data communication services and highway vehicle sub-meter high-precision navigation and positioning are realized, lanes where vehicles are located are identified accurately, illegal acts such as overspeed and road occupation of the vehicles are judged, accident information is identified through fixed-point monitoring and fixed-point cruising of unmanned aerial vehicles, along-highway meteorological information is acquired in real time, warning information is released in time, and snow-melting agent is sprayed automatically in snowy and frosty weather so as to guarantee traffic safety.

Description

technical field [0001] The invention relates to a traffic communication navigation monitoring and early warning device and a working method of a special-domain strip private network, especially for expressway communication navigation monitoring and early warning scenarios, and belongs to the technical field of intelligent transportation and monitoring, navigation and positioning. Background technique [0002] With the rapid development of my country's transportation industry, the mileage of expressways has increased year by year. Road accidents also occur from time to time, bringing great losses to the country and people's life and property safety. [0003] To ensure driving safety on expressways, one is to eliminate traffic violations on expressways, the other is to establish a real-time and efficient monitoring and early warning system, and the third is to formulate solutions to resist severe weather conditions. Vehicle violations on highways mainly include speeding and il...
