Network architecture system connected with various automatic driving sensors

Abstract

The embodiment of the invention relates to a network architecture system connected with various automatic driving sensors. The network architecture system comprises a first camera cluster, a first inertial navigation system, a first laser radar cluster, a first millimeter wave / microwave radar cluster, a first switch, a second switch, a first wireless router, a first data computing platform, a second data computing platform and a first CAN bus. According to the network architecture system, seven different network segments are set, and an equipment direct connection mode is adopted in the multiple network segments, so that the problems of data queuing, blocking, loss and the like caused by switching equipment are avoided; and the data transmission efficiency of the original two-stage switching network architecture is greatly improved without additionally arranging a complex sensor hub or additionally arranging more complex and expensive network switching equipment, the system transformation cost is saved, and the system transformation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a network architecture system connecting various automatic driving sensors. Background technique [0002] Autopilot vehicles often integrate a variety of autopilot sensors, such as cameras, lidar, millimeter wave radar, microwave radar, inertial navigation system (Inertial Navigation System, INS), etc. Computing computing platform. In order to establish a data transmission channel between the above-mentioned various autonomous driving sensors and the computing platform, it is necessary to create a local network architecture for connecting various autonomous driving sensors for all connected devices. The connection relationship between all autonomous driving sensors and computing platforms, on the other hand, also needs to have the function of connecting with other vehicles' local area network or remote network. The conventional network architecture is a two-level switch...

Problems solved by technology

In practical applications, we found that during the actual operation of autonomous vehicles, a large amount of sensing data will be generated. If these data are transmitted through the same switch at the same time, the instantaneous data volume will often exceed the switching capacity of the switching device, resulting in transmission congestion. , data loss, etc.
