Embodiment Construction

[0056] The present invention provides a specific vehicle crossing priority radar detection method and system thereof. In order to make the present invention more obvious and understandable, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0057] Such as figure 1 As shown, the specific vehicle intersection priority radar detection system of the present invention includes a vehicle-mounted host, a roadside host and a host computer. Wherein, the roadside host computer is respectively connected with the vehicle host computer and the host computer through communication.

[0058] The vehicle-mounted host computer of specific vehicle is provided with vehicle-mounted all-in-one machine communication interface (vehicle-mounted all-in-one machine is the multimedia device that carries on the vehicle), vehicle-vehicle unit and wireless communication equipment. The communication interface of the vehicle-mounted...

Abstract

The invention discloses a specific vehicle intersection priority radar detection method and a system thereof. The method includes the following process that: the vehicle-mounted host machine of a vehicle sends distance measurement signals to a roadside host machine, performs vehicle distance and vehicle speed calculation, and sends a first data packet to the roadside host unit; after receiving thefirst data packet sent by the vehicle-mounted host machine, the roadside host machine correspondingly sends an induction data packet to the vehicle-mounted host machine; and the roadside host machineperforms vehicle distance calculation, and sends a vehicle-to-vehicle cooperative data packet containing distance measurement information to the vehicle-mounted host machine. The specific vehicle intersection priority radar detection method and the system thereof of the invention is compatible with a communication function when realizing the real-time positioning of the vehicle; the specific vehicle intersection priority radar detection method and the system thereof of the invention can improve the travel efficiency of people, exert a maximum effect, and save a lot of costs for the work and later maintenance of a system; and the method and the system of the invention are not affected by occlusion situations above a road and are easy to maintain in later stages.

Description

technical field [0001] The present invention relates to the field of radar signal processing and communication transmission, in particular to a specific vehicle crossing priority radar detection method and system thereof. Background technique [0002] With the increasingly severe urban traffic situation, it is imminent to study the priority radar detection system for specific vehicle intersections. Many cities have built bus lanes, subways, trams and BRT multi-modal bus systems, but the bus trip rate in most cities is below 15%. [0003] Considering my country's densely populated and land-scarce national conditions, giving priority to the development of public transport with the highest passenger transport efficiency is the main direction to solve the problem of traffic congestion. The construction cost of multi-mode bus system is high, and it is difficult to realize; and the method of opening up bus lanes is the mainstream practice in most cities at present. However, even...
