Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned driving, and in particular relates to a vehicle-mounted directional RTK positioning device. Background Art

[0002] An autonomous vehicle, also known as a driverless car, a computer-driven car or a wheeled mobile robot, is a smart car that achieves unmanned driving through a computer system.

[0003] Self-driving cars rely on artificial intelligence, visual computing, radar, monitoring devices and global positioning systems to work together, allowing computers to automatically and safely operate motor vehicles without any active human operation.

[0004] In GPS measurements, static, fast static, and dynamic measurements all require post-calculation to obtain centimeter-level accuracy. RTK real-time differential positioning is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. Its emergence has greatly improved field work efficiency.

[0005] In the traditional RTK operation mode, the base station transmits its observation values ​​and station coordinate information to the mobile station through a data radio. The mobile station receives the data from the base station and also collects GPS observation data for real-time processing, while providing centimeter-level positioning results. However, due to the influence of the environment and power attenuation, traditional data transmission radios cannot achieve the expected data transmission effect and distance when blocked by obstacles such as buildings or mountains.

[0006] When a driverless car is running, GPS is required to perform remote intelligent control and navigation of the vehicle. Currently, most driverless cars use RTK positioning for car navigation and positioning. In rainy weather, when a driverless car is driving on the road, rainwater will accumulate on the surface of the RTK positioning device. The rainwater seeping into the device will affect the positioning effect of the RTK positioning device. The mirror of the camera group will be blocked by rainwater, affecting the navigation of the car. The signal frequency of RTK positioning fluctuates due to the influence of the environment when driving on the road. The device cannot raise and lower the RTK positioning by itself to find the best signal. There are limitations in the use of the device.

[0007] In view of this, the present utility model is proposed. Utility Model Content
