After the internet of vehicles module starts, the network channel is firstly authenticated in a bidirectional way, and the network aimed by the bidirectional authentication is the network where the internet of vehicles service API provided by the internet of vehicles platform is located. Before bidirectional authentication, the program acquires a client certificate, a root certificate and a client key required by the bidirectional authentication from the system through a decryption algorithm, and after the acquisition is successful, the program completes a certificate exchange process of the bidirectional authentication with a server where the Internet of vehicles service is located under the condition that the network state is normal, and if the network state is abnormal, the program continues to try to perform the bidirectional authentication.

The public network access service refers to that the vehicle-mounted application uses a public network access interface provided by the internet of vehicles module to perform public network access, as shown in fig. 5. Similar to the request of the Internet of vehicles service network, the public network access flow is as follows, before public network access is carried out, whether the current public network state is available is firstly judged, and when the network state is unavailable, the network state abnormality of a request initiator is directly returned. The network state is available, the network access parameters are standardized (the network access parameters are encapsulated for the second time), the standardized public network access request is added into the request queue, the network request is initiated, and the result of the network request is returned.
After receiving the request of the bullet frame, the bullet frame management component firstly carries out anti-shake filtration to filter out the similar bullet frames; then judging the current bullet frame state: if the bullet box is currently being displayed, the current bullet box is preferentially hidden, and then the generation, loading and display of the bullet box are performed.
