Intelligent cone barrel based on fusion positioning technology

Abstract

The invention discloses an intelligent cone barrel based on a fusion positioning technology. The intelligent cone bucket comprises a UWB ultra-wideband positioning module, a LoRa wireless positioning module and a Beidou satellite positioning module. According to the intelligent cone barrel, UWB ultra wide band positioning which has the characteristics of high data transmission rate, strong multipath interference resistance, strong penetrating ability, low interception rate, sharing frequency spectrum with other existing wireless communication systems and the like, and LoRa wireless positioning which has the characteristics of low power consumption, long distance, strong anti-interference performance and penetrability are used as effective supplements of Beidou satellite positioning; and three positioning information fusion optimization methods are provided, so that the intelligent cone bucket can be suitable for closed space scenes such as tunnels and underground parking lots, and the positioning precision of products is improved.

Description

technical field [0001] The invention belongs to the technical field of road safety, in particular to a smart cone bucket based on fusion positioning technology. Background technique [0002] Traditional cone barrels, also known as cone road signs and cone barrels, are a road traffic isolation and warning facility. The main purpose is: set up around places that need to temporarily separate traffic flow, guide traffic, guide vehicles to bypass dangerous road sections, and protect construction site facilities and personnel. Widely used in highways, intersection lanes, road construction sites, and dangerous areas, it is an important traffic safety facility necessary for traffic control, road administration, and road maintenance units. [0003] At present, the level of new infrastructure in my country is developing rapidly. In the transportation industry, new technologies and new equipment such as "Beidou+", Internet of Things, 5G communication, vehicle-road coordination, and dr...

Problems solved by technology

[0003] At present, the level of new infrastructure in my country is developing rapidly. New technologies and new equipment such as "Beidou+", Internet of Things, 5G communication, vehicle-road coordination, and driverless driving continue to emerge in the transportation industry. The traditional cone barrel without any sensing and interactive components can no longer Meet the road traffic safety management requirements under my country's new infrastructure, especially the application requirements for unmanned driving and vehicle-road coordination scenarios

[0004] Using advanced technologies such as "Beidou+", big data fusion, and the Internet of Things to implement intelligent transformation of the cone barrel, on the one hand, promote the deep integration of my country's "Beidou+ Transportation" and promote the development of the "Beidou+" industry; on the other hand, improve transportation The intelligent level of safety equipment improves the level of traffic safety management; however, Beidou satellite positioning technology has all-weather and global positioning capabilities, but it will be affected by environmental factors such as weather, geographical location, and signal shadowing, and there may be signal loss or insufficient accuracy In the tunnel scene, the problem of loss of positioning signal or insufficient accuracy due to mountain occlusion is particularly prominent, which is the technical bottleneck of the current "Beidou+" technology promotion in the transportation field
