Description

Beidou satellite-based road height-limiting fence navigation early warning and remote supervision system and method

Technical Field

The invention belongs to the technical field of road height limit fence warning, and particularly relates to a Beidou satellite-based navigation early warning and remote supervision system and method for a road height limit fence.

Background

At present, national highway networks and railway networks are more and more dense, and railway underpass culverts and viaduct type door openings exist from ground roadbed type to viaduct type no matter the urban area is passed through, suburbs and urban areas; the highway tunnels in rural areas in China and the national tunnels in mountainous areas are mostly not electrified, and holes and even holes are not illuminated. The warning anticollision door that sets up on tunnel entrance to a cave or county country road, its height does not design according to national standard, and is comparatively chaotic. The height of the underpass culvert is generally lower on the ground roadbed type railway passing by a farmland and villages. Some are pedestrian culverts, drainage culverts and some are vehicle passing culverts, and vehicles running on roads (including villages and tractor ploughs) pass through the railway culverts. Urban railways often separate a city into two parts, with more traffic. The expressway network distributed in the whole country divides the land of a plurality of natural villages and administrative villages and villages into two parts, culverts are throats which various vehicles passing through the land must pass through, more and more vehicles are produced in rural logistics, and accidents of hitting a height-limiting fence often occur. No night lighting device is installed on an anti-collision door limit high fence which is arranged on suburb bridges in China due to limit exceeding (bridge design limit load or bridge load limit). Height-limiting columns arranged on all ordinary roads in the country are different in height and are very disordered, and the height-limiting columns are from 2.1 meters to 5.8 meters, and only on expressways are in comparison standard.

With the rapid development of logistics freight and electronic commerce, truck drivers are really a very large social group. According to statistics, about 3000 million truck driver practitioners currently exist in China, 1500 million existing road freight vehicles are achieved, and 8400 goods of more than ten thousand tons are transported on the way on average every day. Due to the strong requirements of long-term, long-distance and multi-frequency trip, truck drivers have high dependence on mobile phone maps and navigation applications.

The truck is the highest requirement for navigation and map data fineness in all vehicle types. Because the trucks are strictly limited in height, width, weight and traffic, and the like on the road, once the trucks enter the restricted road section, the trucks are difficult to turn around, so that fine payment is required to be paid against regulations, road congestion is possibly caused, and even safety risks are caused. Many similar cases have occurred this year. In 11 th decade of the year, under a road overpass built by three west rings in Zheng Zhou city, a refrigerated vehicle is clamped under the overpass when passing through a bridge with the height limited by 3 meters, and the traffic data shows that the peak value of the congestion delay index (the higher the travel time of the traffic congestion/the travel time of free flow passing, the higher the index is, the more serious the congestion is) of the relevant road section after the accident happens reaches 4.11 once, and the congestion delay index is about 8 hours in all days and is more than 1.8.

The height-limiting columns are generally anti-collision steel structure facilities, yellow and black warning signs and luminous material signboards, are fuzzy in the daytime, invisible at night and remote, and cannot meet the requirements of modern life rhythm. This puts new demands on the road height limit sign. The driver needs to see clearly in the daytime and be eye-catching at night, and needs to see clearly information such as height limit, width limit, weight limit, driving limit and the like, and the information can be obtained before starting.

Almost all height-limiting fences in China develop not together with the time, still stay in the anticollision door grade of initial stage, are not striking at night and in dense fog days, and the high warning board is unclear and non-uniform at night, and is very chaotic from 2.4 meters to 5.0 meters. The commonly seen navigation map is a map suitable for passenger vehicles, and information of height limitation, width limitation, weight limitation, traffic limitation and the like of height limitation columns on common roads except national expressways is not implanted; 3000 thousands of truck drivers exist in the country, and the electronic map navigation function required by the truck drivers is important and urgent for selecting transportation routes and accurately and timely acquiring traffic information such as restriction, height limitation, weight limitation and the like on the passing roads.

Through the above analysis, the problems and defects of the prior art are as follows: in the prior art, the height limit fence is not striking at night and in dense fog days, and the height value of the height limit fence is not easy to see clearly. Meanwhile, the existing navigation map cannot meet the requirement that drivers of freight transport nationwide efficiently, reasonably and timely accurately select driving routes of destinations of goods collectors.

The difficulty in solving the above problems and defects is: the traditional warning sign reflective film or luminous paint of the height-limiting column does not emit light, and the warning sign is far away in the daytime and cannot be seen at all; the light-reflecting film can only be irradiated by the car light to generate weak light reflection at night and can be seen only in front of the car; the LED lamp is not designed to be active to emit light, and mainly solves the problem of power source. The source problem that the electric energy source is difficult to solve is that a constructor of the height-limiting fence consists of all units, and the construction units cannot specially construct power supply lines for the height-limiting fence. And after the title unit builds the height-limiting column, the title unit is usually maintained without people.

The significance of solving the problems and the defects is as follows: the invention takes no need of electric power supply as a research target, adopts a program software control technology, adopts a modern low-power consumption light-emitting chip technology and a new energy and energy storage technology, meets the light-emitting warning effect under all-weather and any weather conditions, has the eye-catching visibility reaching beyond 100 meters, and provides night/day long-distance eye-catching height-limiting indication warning effect for a driver driving a railway line quickly; the warning device has an effective function for night lightening warnings of non-electric tunnel portal height-limiting fences of urban and rural roads, national roads, provinces, counties, towns and rural roads in mountainous areas, bridges of load-limiting highways, height-limiting fences of dangerous bridges and height-limiting fences of bridges under overpasses in urban areas, and the like.

According to the invention, the Beidou map database is connected through the 4G internet, real-time updated data such as height limit, width limit, weight limit, traffic limit and the like are added to the Beidou navigation map, a new technology, cloud service, new energy and the like are used for lightening, warning and reminding, the function of the Beidou navigation map is fully exerted, and national height limit columns are integrated into the Beidou navigation map. For the height-limiting fence set in violation, blocked drivers are encouraged to directly complain to the national monitoring platform by using WeChat small programs on site. The national monitoring platform utilizes cloud platform big data to mobilize Beidou satellite image data, remotely checks the privately-arranged road height limit fence on rural roads in suburbs, so that the supervision level and supervision efficiency of the national transportation department are improved, the supervision process and evidence obtaining difficulty of local administrative departments are reduced, the supervision cost is reduced, fair supervision is facilitated, and the relation condition is eliminated.

Because the level of the MCU module is 3.3V and the level of the serial port module (MAX232) is 5V, the MCU module and the serial port module cannot be directly connected, and the level conversion of 3.3Vto 5.0V and 5.0Vto 3.3V is realized through the bidirectional level conversion module;

When they are connected to each other, level conversion is necessary. The power supply is powered by a +5V single power supply. The power supply of the serial port module is taken from the 4G communication module.
