Embodiment 1

[0042] This embodiment provides a method for measuring the positioning accuracy of a vehicle-mounted terminal based on a cloud platform, which is applied to a measurement cloud platform, and the vehicle-mounted terminal and a reference instrument are installed on a mobile vehicle. The instrument is used to collect reference position data of moving vehicles, see figure 1 , the method includes:

[0043] First, step S1 is performed: receiving terminal location data collected by a preset vehicle-mounted terminal, wherein the terminal location data includes first time data and first spatial location data.

[0044] Specifically, on-board terminals and reference instruments are installed on each moving vehicle. The vehicle-mounted terminal is connected to the Internet of Vehicles cloud platform, and the terminal data collected by different vehicle-mounted terminals is sent to the Internet of Vehicles cloud platform. In the specific implementation process, the terminal data collected...

Embodiment 2

[0065] This embodiment provides a device for measuring the positioning accuracy of a vehicle-mounted terminal based on a cloud platform. The device is a measurement cloud platform. Please refer to figure 2 , the device consists of:

[0066] The receiving module 201 is configured to receive terminal location data collected by a preset vehicle-mounted terminal, wherein the terminal location data includes first time data and first spatial location data;

[0067] The first matching module 202 is used to match the preset vehicle-mounted terminal with the reference instrument to obtain target reference position data, wherein the target reference position data includes second time data and second spatial position data;

[0068] The second matching module 203 is configured to match the first time data with the second time data through the measurement cloud platform, and calculate the difference between the first spatial position data and the second spatial position data when the matc...

Embodiment 3

[0076] Based on the same inventive concept, this application also provides a measurement system for positioning accuracy of vehicle-mounted terminals based on a cloud platform, such as image 3 As shown, the system includes a cloud platform for the Internet of Vehicles, a cloud platform for instrumentation management, and the device described in the second embodiment.

[0077] In one embodiment, the measurement cloud platform is respectively connected to the cloud platform of the Internet of Vehicles and the cloud platform of instrumentation management to perform data interaction with the cloud platform of the Internet of Vehicles and the cloud platform of instrumentation management. The Internet of Vehicles cloud platform and the instrumentation management cloud platform are independent of each other.

[0078] Specifically, through the docking and coordination of the three cloud platforms, the online real-time dynamic positioning accuracy measurement of multiple vehicles can ...

Abstract

The invention provides a method, device and system for measuring positioning precision of a vehicle-mounted terminal based on a cloud platform. The method comprises the following steps of: obtaining atarget object; the measurement cloud platform receives terminal position data collected by the preset vehicle-mounted terminal; matching the equipment identity identification code of the preset vehicle-mounted terminal with the identity identification code of the reference instrument, matching the first time data with the second time data after the identity identification code is successfully matched, calculating the distance between the first spatial position data and the second spatial position data when the matching is successful, and expressing the distance as a difference value; And finally, determining the positioning precision of the vehicle-mounted terminal according to the difference value. The technical effect of improving the operability and the online real-time performance ofmeasurement is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle network location service application, in particular to a method, device and system for measuring positioning accuracy of a vehicle terminal based on a cloud platform.
