Embodiment
See Fig. 1, it is the data transmission method process flow diagram of a kind of automobile transmission storer that the present invention proposes.
As shown in Figure 1, a kind of data transmission method of automobile transmission storer, is characterized in that, comprise the following steps:
Connect wifi;
Smart machine and hardware are set up socket and are connected;
V radio station disk is mounted to above the operating system of hardware;
The WebDav that smart machine is provided by V radio station serves data with existing in reading disk;
Determine and need different audio frequency;
Isochronous audio is on the disk in V radio station;
V radio station disk is mounted on automobile;
Disconnect wifi.
Smart machine described in the present invention is mobile phone.
In the embodiment of the present invention, in time opening V radio station, V radio station can start the service of a WebDav automatically, and WebDav service is the kernel service of mobile phone A pp and V radio station synchrodata, is the basis of data syn-chronization;
When user opens App time, mobile phone application can be set up a Socket with V radio station and is connected, and represents that application has been connected with Socket;
From this time, there is voice data in App on WebDAV acquisition request V radio station, and then with inside App App applies the audio frequency downloaded and compare, and determines the audio frequency that needs are synchronous.Needs synchronous documents is put into inside a queue and goes, program to be synchronized processes;
Synchronization program can pull successively inside queue needs synchronous audio frequency, is synchronized to V radio station and gets on.Recurrence successively, until synchronously complete;
After synchronously completing, need to allow user can use V radio station on automobile, and allow user get back in conventional network environment to go.This time, App can send an order to V radio station, required disk to change into from carry in V radio station to be mounted on automobile, from then on started, and the middle control of automobile just can audio frequency in normal play V radio station;
