[0103] Based on the first embodiment above, before the step S10, the tunnel-based network switching method of this embodiment further includes:

[0104] Step S01: Obtain the target driving route of the target movable carrier, and send the target driving route to the server, so that the server can determine the target tunnel information according to the target driving route, and according to the target Tunnel information determines the corresponding network heat map, determines each main Internet of Things card road section and each main Internet of Things card road section to replace the secondary Internet of Things card according to the network heat map, and The substituting secondary IoT card on the card section generates the preset tunnel IoT card switching strategy, and feeds back the preset tunnel IoT card switching strategy to the target removable carrier.

[0105]It should be noted that, after obtaining the destination information set by the user, the target driving rou...

Abstract

The invention belongs to the technical field of automatic driving, and discloses a tunnel-based network switching method and device, a movable carrier and a storage medium. The method comprises the steps: when the target movable carrier is located in the target tunnel, obtaining the current tunnel position where the target movable carrier is located; detecting signal bandwidth information of each Internet of Things card on the target movable carrier at the current tunnel position; selecting a target Internet of Things card from the Internet of Things cards on the target movable carrier according to a preset tunnel Internet of Things card switching strategy, the current tunnel position and the signal bandwidth information of the Internet of Things cards at the current tunnel position; according to the network weight value of each Internet of Things card, determining whether to select a default main card as a target Internet of Things card; if the target Internet of Things card is not the main Internet of Things card, switching the target Internet of Things card to the main Internet of Things card. Through the mode, the Internet of Things card with stable network signals can be selected as the main card in the tunnel, so that the purpose of stable connection is achieved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a tunnel-based network switching method, device, removable carrier and storage medium. Background technique [0002] With the development of autonomous driving technology, the driving scenarios faced by mobile carriers are becoming more and more complex. Thanks to the development of wireless communication technology, autonomous driving can solve more and more scenarios, but the driving of mobile carriers requires a stable network. Communication, and in some bad network scenarios, the removable carrier of a single IoT card often loses packets or even disconnects in many places with poor signals. It takes at least a few seconds for the application to disconnect and reconnect, which is very dangerous for removable carriers. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the...
