Abstract

The invention is suitable for the technical field of smart traffic, and provides a multi-layer road surface equipment communication method and device and a computer readable storage medium. The method is applied to the vehicle-mounted equipment and comprises the steps of obtaining air pressure of the position of the vehicle-mounted equipment; receiving a broadcast message from other equipment, wherein the broadcast message comprises the air pressure of the position of the other equipment; the pressure difference between the air pressure of the position where the vehicle-mounted equipment is located and the air pressure of the positions where other equipment is located is determined; and if the pressure difference is within the preset range, determining that the vehicle-mounted equipment and other equipment are on the same layer of road surface. The vehicle-mounted device can determine other devices on the same layer of road surface according to the air pressure, communication can be achieved accordingly, route calculation and positioning correction are not needed, and a large amount of operation is reduced; meanwhile, the situation that traffic safety and user experience are affected by wrong response to messages caused by communication crosstalk can be avoided, and communication reliability and pertinence can be improved.

Description

technical field [0001] The present application belongs to the technical field of smart transportation, and in particular, relates to a device communication method, device and computer-readable storage medium for a multi-layer road. Background technique [0002] With the rapid development of the smart transportation industry, the application requirements for specific scenarios of V2X (vehicle to everything, that is, the exchange of information between vehicles and the outside world) are gradually increasing. In the scenario of multi-layer roads (such as viaducts, overpasses, underground tunnels, etc.), the upper and lower lanes are criss-crossed, while the traditional V2X antenna is an omnidirectional antenna, and the signal range of a V2X roadside base station on a road may cover multiple upper and lower lanes. Layer lanes, vehicles on a certain layer lane are easily confused to receive traffic information from V2X roadside base stations on other layer lanes, affecting traff...
