Abstract
The invention discloses a vehicle-mounted DA system interface switching system based on a Linux platform. The vehicle-mounted DA system interface switching system comprises an automobile multimedia which is internally provided with a vehicle-mounted DA system. The automobile multimedia adopts the Linux operating platform and is provided with a USB interface end and an OTG interface end. A switcher is connected to the USB interface end and the OTG interface end. A switching button is arranged on the automobile multimedia. A driver switches the USB interface end and the OTG interface end by operating the switching button. Switching use is conducted by arranging the USB interface end and the OTG interface end so that data transmission of different digital devices can be facilitated.
Description
Technical field
The present invention relates to interface switch system, more particularly to a kind of USB and OTG based on the vehicle-mounted DA systems of Linux platform
Switched system.
Background technology
With the development of science and technology, automobile is as scooter and popularizes each family, and multimedia would generally be matched in automobile
For driving recording or music broadcast or navigation function are listened, but, existing multimedia interface simply uses a USB mostly
Interface, only uses for mobile phone or PC, and this is resulted in other digital products and the conduction of data can not be carried out with car multimedia, because
This, solves the problems, such as that this class is particularly important.
The content of the invention
For the deficiencies in the prior art, the invention provides a kind of interface based on the vehicle-mounted DA systems of Linux platform switches
System, is provided by USB interface end and OTG interface ends to switch over use, to solve existing car multimedia using effect
The low problem of rate.
In order to solve the above problems, the invention provides a kind of interface switching system based on the vehicle-mounted DA systems of Linux platform
System, includes car multimedia, vehicle-mounted DA systems is provided with the car multimedia, and the car multimedia adopts Linux
Operating platform, is provided with USB interface end and OTG interface ends, connects in the USB interface end and OTG interface ends on car multimedia
Switch is connected to, on the car multimedia, switching push button is provided with, by driver by switching push button being operated come to USB interface
End and OTG interface ends are switched over.
Further improvement is that：Bluetooth module is provided with the car multimedia so that mobile phone and car multimedia phase
Connect, driver is connected with multimedia by mobile phone.
Further improvement is that：What car multimedia started under initial state is USB interface end, in the OTG interfaces
Start button is provided with end, when push button is on, OTG interface ends can just carry out the conduction of data.
Further improvement is that：Voltage buffer interface end, data are provided with the USB interface end and OTG interface ends
Line is connected with USB interface end or OTG interface ends by voltage buffer interface end, during preventing automobile from just starting or closing suddenly,
Voltage instantaneous become big and damage digital equipment.
The invention has the beneficial effects as follows：The present invention is provided by USB interface end and OTG interface ends, and driver can pass through
Switching push button is conducted with the data for facilitating different digital equipments, and driver of the present invention can carrying out the conversion of interface modes
By bluetooth, car multimedia is controlled by mobile phone.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is further described below in conjunction with embodiment, the present embodiment
It is only used for explaining the present invention, does not constitute limiting the scope of the present invention.
A kind of interface switch system based on the vehicle-mounted DA systems of Linux platform is present embodiments provided, automobile is included many
Media, are provided with vehicle-mounted DA systems in the car multimedia, the car multimedia adopts Linux operating platforms, and automobile is more
USB interface end and OTG interface ends are provided with media, in the USB interface end and OTG interface ends, switch is connected with, it is described
Switching push button is provided with car multimedia, by driver by switching push button being operated entering to USB interface end and OTG interface ends
Row switching.Bluetooth module is provided with the car multimedia so that mobile phone is connected with each other with car multimedia, driver passes through
Mobile phone is operating multimedia.What car multimedia started under initial state is USB interface end, is set in the OTG interface ends
Start button is equipped with, when push button is on, OTG interface ends can just carry out the conduction of data.At the USB interface end and
Voltage buffer interface end is provided with OTG interface ends, data wire is by voltage buffer interface end and USB interface end or OTG interfaces
End connection, during preventing automobile from just starting or closing suddenly, voltage instantaneous become big and damage digital equipment.
The present invention is provided by USB interface end and OTG interface ends, and driver can enter line interface mould by switching push button
The conversion of formula, is conducted with the data for facilitating different digital equipments, and driver of the present invention can be by bluetooth, by mobile phone to automobile
Multimedia is controlled.
