Problems solved by technology

The satellite navigation system, due to the influence of the strength and accuracy of the satellite receiving signal, cannot be very effective when the satellite signal is blocked or within a few meters of the accuracy requirement (beyond the accuracy range of satellite signals such as civilian GPS), or when inside a building play a role

Embodiment 1

[0031] Example 1 This road navigation system replaces the driving navigation of the existing GPS navigation system

[0032] The system has been fully deployed on the roadway in an urban area, and the installation density of the coordinate points of the pavement molecular system is sufficient to distinguish two different roadways on the road surface where the roadway needs to be identified; To distinguish the road surface of the roadway, the installation density is sufficient to distinguish the road. A vehicle is going from point A to point B. The driver of the vehicle turns on the navigation terminal installed on the vehicle, and the signal receiver on the navigation terminal tries to receive the signal transmitted from the coordinate point on the ground below the vehicle. Due to the deployment density of the coordinate points, the vehicle navigation terminal may not be able to receive the information transmitted by the coordinate points in the initial state. If the cover...

Embodiment 2

[0033] Example 2 This pavement navigation system is used for passenger navigation at railway stations

[0034] The scale of the current railway stations and high-speed rail stations is generally very large. In order to find a specific ticket office, restaurant, toilet, entrance and exit, or meet others at a specific location, it may take a lot of asking for directions, and it takes a long time to go the wrong way. It is especially inconvenient when carrying luggage. To apply this road navigation system, it is first necessary to map the layout of the railway station, establish a map database of each floor and floor plan of the railway station, and label the location according to the required accuracy requirements; then install the coordinate points to the location On the label, it can be the road surface of each floor, or the indoor ceiling of each floor, and the above-mentioned electronic map and coordinate point position information are uploaded to the road signal server. ...

Embodiment 3

[0035] Example 3 This road navigation system evaluates road traffic conditions

[0036] Assuming that the system has been fully deployed on the roadway in an urban area, and the navigation terminal of the system has been installed on most vehicles, and the navigation terminal is turned on when driving, the coordinate points on the road will receive a large number of traffic signals from the vehicle. According to the transmission signal of the navigation terminal, according to the vehicle information contained in the transmission signal, the road coordinate points transmit this information to the road information server, and can estimate the traffic flow, traffic speed, vehicle density and other information in a certain area or a certain road section .

[0037] If there is no navigation terminal installed on most vehicles, the coordinate point on the road sends a signal directly above it, but no reflected signal is received, and it can also be judged whether there is a vehic...

Abstract

The invention discloses a pavement navigation system. The pavement navigation system comprises a pavement section subsystem and a terminal section subsystem, wherein the pavement section subsystem mainly comprises coordinate points arranged on pavement; the terminal section subsystem mainly comprises a navigation terminal mounted on a vehicle or handheld by a pedestrian; the navigation terminal reads information of the pavement coordinate points, locates the present accurate position through the information, and acquires a specific pathway to a destination; the pavement coordinate points read the information of the navigation terminal; the information read by a plurality of coordinate points is collected to a pathway information server. The pavement navigation system is broad in application range, applied to outdoor or indoor environments which comprise but not limited to urban pathways, expressways, fields, caves, tunnels, airport terminals, railway stations, bus-stops, hospitals, large-scale markets and large-scale exhibition buildings; accuracy of positioning is high; accuracy of positioning at 1 meter level even 0.1 meter level can be provided according to the density of mounted and deployed coordinate points; anti-interference ability is high.

Description

technical field [0001] The invention relates to a road navigation system, which is used to help vehicles, pedestrians and robots obtain their own position information in the current environment and a specific path to a destination, and is suitable for navigation in outdoor and indoor environments. Background technique [0002] The current road navigation mainly relies on two types of information, one is visual navigation information such as road signs and road signs on the road, and the other is a satellite navigation system based on GPS satellites or Beidou satellites. [0003] Due to smog, smog, light visibility, unreasonable road sign setting, front car occlusion, damaged road signs and road signs, complex information at road intersections and drivers are not familiar with the area, etc., the naked eye visibility of road signs and road signs on the road For navigation information, sometimes the driver needs to drive very close (so close that there is no way to change it i...
