Vehicle height limit early warning method and system based on Internet of things, and vehicle

Abstract

The invention provides a vehicle height limit early warning method based on the Internet of things. According to the vehicle driving height limit early warning method, height limit information of a first vehicle provided with a height limit detection device is collected, and a Internet-of-things server sends the height limit information of a corresponding road section to a second vehicle accordingto the vehicle information of the second vehicle, so that the height limit information is provided for the second vehicle passing through the same road section, and the second vehicle performs driving height limit early warning according to the height limit information, therefore, the height limit detection device does not need to be installed on the second vehicle, and the installation number ofthe height limit detection device is reduced. In addition, the height limit detection device is mounted right above the vehicle, so that the detection precision is greatly improved; the height limitinformation is obtained by detection and calculation in a real passing state of a height limit road section, therefore, the problem that the real road condition is not completely consistent with the marked height limit information is solved, the calculation of the height limit information is more real and accurate, the deviation between the measurement result and the actual traffic road conditionis reduced to the maximum extent, and the safety traffic efficiency of vehicles with the vehicle height near the height limit is improved.

Description

technical field [0001] The present application relates to the technical field of the present invention relating to the Internet of Things and vehicle height limit early warning, in particular to a vehicle height limit early warning method and system based on the Internet of Things, and a vehicle. Background technique [0002] With the improvement of our country's science and technology and economic level, there are more and more types and quantities of vehicles. For the protection of roads and the personal safety of drivers, some roads will be set with height limiters or poles; height limiters are generally used for bridges, The portal frame at the entrance of culverts and tunnels plays a protective role. Due to the emergence of various models, road planning is also being updated rapidly, and the height of the height limit pole is also different. Originally, the height limit pole is to protect the safety of drivers, passengers and goods, but because the height of most height...

Problems solved by technology

[0006] However, the above-mentioned documents all need to install a height limit detection device inside each vehicle to be able to provide a height limit warning for the vehicle, and the vehicle height limit will only be encountered in a very small number of road sections, so the use of the height limit detection device The rate is extremely low, but the above literature still needs to install a height limit detection device for each vehicle to be able to provide height limit warning for all vehicles, thus greatly increasing the economic burden of car owners, and unnecessary installation of height limit detection devices results in a waste of resources. Great waste, greatly reduced economic benefits

In addition, the passable height calculated in the above literature is obtained by detecting and calculating the vehicle in front of the vehicle (that is, the side) through the detection device when the vehicle is not passing on the real height-limited road section. The method is unavoidably affected by unfavorable factors such as real road conditions (such as uneven road damage) and low side detection accuracy of the detection device. As a result, the height limit causes deviations between the detection results and the actual traffic conditions, which will cause the height of the vehicle to exceed the limit. The problem that vehicles near the height cannot pass safely
