Problems solved by technology

However, large-scale high-density three-dimensional garages have the following two problems. First, the second type of vehicle-mounted intelligent terminal will automatically wake up at regular intervals. After waking up, it will perform positioning and then upload the positioning data.
In the second aspect, in order to give way to other vehicles in the three-dimensional garage in the three-dimensional garage, the position of the vehicle may frequently move horizontally or vertically, which will cause the third type of vehicle-mounted intelligent terminal to be frequently wake
Therefore, the high-density storage of vehicles in the three-dimensional garage may occupy more channel resources. At the same time, frequent request signals will also increase the computing pressure of the channel scheduling equipment, thereby affecting the use of channels by nearby personnel.

Embodiment 1

[0053] First of all, it should be explained that Embodiment 1 of the present invention is preferably applicable to a parking lot terminal. The parking lot terminal is an integral part of the vehicle intelligent positioning system based on the Internet of Vehicles, which provides protection for the vehicle intelligent terminal, parking lot terminal and server that interact with each other. The execution of Embodiment 1 of the present invention can be triggered after the user's vehicle enters the parking lot, or the effective communication range of the signal transmission equipment of the parking lot terminal.

[0054] figure 1 A schematic flow chart of the vehicle data interaction method based on the Internet of Vehicles provided by the embodiment of the present invention, as shown in figure 1 As shown, the method includes:

[0055] S101: After sensing that the vehicle equipped with the vehicle-mounted intelligent terminal enters the parking lot, or enters the monitoring area...

Embodiment 2

[0076] It should be emphasized that the vehicle to which Embodiment 2 of the present invention is applied can be the vehicle mentioned in Embodiment 1, or other vehicles that have not entered the parking lot, for example, vehicles passing by the camera shooting range at the gate of the parking lot, or vehicles in the parking lot Vehicles within the radiation range of the signal transceiver equipment at the parking lot.

[0077] On the basis of Embodiment 1 of the present invention, Embodiment 2 of the present invention also adds the following steps:

[0078] S104 (not shown in the figure): the camera captures images of the vehicle, and the captured images include pre-marked positioning points.

[0079] The image of the vehicle is captured by the camera, and then the central processing unit uses the optical perspective method to calculate the distance from the vehicle to the camera based on the predetermined size of the object in the image, such as the width of the lane line; o...

Embodiment 3

[0091] When the camera collects the optical signal of the vehicle, as the distance increases, the acquisition error becomes larger and larger, and the error of the first positioning data calculated according to the image of the camera is also larger and larger. The calculation shows that this error increases with the distance The increase of is a non-linear increase. Therefore, the difference between Embodiment 3 and Embodiment 2 of the present invention is that after the vehicle-mounted intelligent terminal receives the first positioning data, the vehicle-mounted intelligent terminal uses the formula, Calculate the confidence level of the vehicle-mounted intelligent terminal to send the second positioning data to the parking lot terminal without calibration message, and send the second positioning data to the parking lot terminal when the confidence level is less than the second preset threshold. The message, wherein,

[0092] P is the confidence level that the vehicle-mounte...

Abstract

The invention provides a vehicle data interaction method and system based on the Internet of Vehicles, and the method and system are applied to a parking lot terminal. The method comprises the steps of: receiving a positioning triggering signal transmitted by a vehicle equipped with a vehicle-mounted intelligent terminal after the vehicle enters a parking lot; responding to the positioning triggering signal, and acquiring positioning data of the vehicle; and summarizing the positioning data of each vehicle, packaging and uploading the data to a server. By applying the embodiment of the presentinvention, channel resources can be saved, and communication efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a vehicle data interaction method and system based on the Internet of Vehicles. Background technique [0002] With the development of microelectronics technology, the advancement of the standardization of vehicle management, and the increasing demand for vehicle safety monitoring, more and more vehicles are equipped with vehicle-mounted intelligent terminals to monitor vehicle positioning data and trajectory data in real time. For example, the vehicle-mounted intelligent terminal can be used to monitor the running track and working status of official vehicles, and then determine whether there are problems such as private use of official vehicles and overuse; Motion estimation and motion status of chemical transport vehicles, escort vehicles, school buses, and cold chain logistics vehicles. In the prior art, vehicle-mounted intelligent terminals are usually used ...
