Abstract
The present invention proposes a kind of USB switching systems based on WiFi, solves the problems, such as the free switching based on the multichannel USB passages under WiFi technology and its control system, the management for realizing car-mounted terminal music and the wireless automatic transmission problem for realizing music file.The system includes master controller, USB switchings switch, EUDM modules, antenna and vehicle-mounted USB interface, and master controller is connected with antenna, and master controller also switches switch and is connected with EUDM modules and vehicle-mounted USB interface respectively by USB.The course of work of the switching system is：Master controller carries out the transmission of data and music file by antenna and external equipment；After vehicle-mounted USB interface is connected with the USB interface of in-vehicle player, usb data passage is switched to vehicle-mounted USB mode by main controller controls USB switching switches, realizes full automatic music playback function；When needing that music file is transferred into EUDM modules by external equipment, usb data passage is switched to EUDM template patterns by main controller controls USB switching switches, realizes the transmission and storage of music file.
Description
Technical field
The present invention relates to the technical field of intelligent wireless transmission, system is switched more particularly, to a kind of USB based on WiFi
System.
Background technology
The free switching technology of the multichannel USB passages not being based at present under WiFi technology and its control system, be all
Single Wi-Fi hotspot technology or the single usb communication technology based on Flash, without ripe effective USB free switchings
Technology and product.
Single USB flash disk technology can be realized carrying out real-time operation by vehicle music control button and can depositing substantial amounts of
Music file.This technical approach realizes that circuit structure is simple by simple Flash chip and USB controller chip.
Single Wi-Fi hotspot technology is by an equipment with WiFi function and the vehicle-mounted master with receive capabilities
Machine is realized.During music, WiFi equipment needs to be connected in real time by WiFi technology with on-vehicle host is received,
WiFi equipment is by music data stream real-time Transmission to on-vehicle host real-time music playing function.
Single USB flash disk technology to carry out music file management aspect weaker, when needing that substantial amounts of music file is carried out
Classification Management, increase are just difficult to, it is necessary to being operated on PC, real-time is poor when deleting.
Single Wi-Fi hotspot technology needs equipment always on, and it is manually opened that the function needs user to carry out, and is playing
During can not directly be operated using the music control button of vehicle, it is necessary to user is operated on playback equipment, lead
Family of applying has disperseed notice, and potential safety hazard is likely to occur in driving conditions.
Single USB flash disk technical circuit design is simple, only provides the memory space of music file, does not have wireless technology and work(
Energy；
Single Wi-Fi hotspot technology real-time Transmission music stream, the on-vehicle host of receiving terminal can only passively receive music data, no
Can be controlled.Product design is complicated, and power consumption is larger.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to propose a kind of USB switching systems based on WiFi, solve to be based on
The free switching problem of the multichannel USB passages under WiFi technology and its control system, realize car-mounted terminal music management and
Realize the wireless automatic transmission problem of music file.
To achieve these goals, the technical scheme is that：
A kind of USB switching systems based on WiFi, including master controller, USB switching switch, EUDM modules, antenna and vehicle-mounted USB
Interface, master controller is connected with antenna, master controller also by USB switch switch respectively with EUDM modules and vehicle-mounted USB interface
Connection.
The course of work of the switching system is：Master controller carries out data and music file by antenna and external equipment
Transmission；
After vehicle-mounted USB interface is connected with the USB interface of in-vehicle player, main controller controls USB switchings are switched USB numbers
Vehicle-mounted USB mode is switched to according to passage, full automatic music playback function is realized；
When needing that music file is transferred into EUDM modules by external equipment, main controller controls USB switchings are switched USB
Data channel switches to EUDM template patterns, realizes the transmission and storage of music file.
Preferably, the master controller is the master controller based on WiFi.
Compared with prior art, beneficial effects of the present invention are：
The present invention will be based on WiFi technology, and realizing the switching of the multichannel USB passages under control system has carried out depth integration, realizes
The management of car-mounted terminal music and realize the wireless automatic transmission problem of music file；Suitable for vehicle electronics technology, wirelessly
The technical field of intelligent transportation.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not
It is limited to this.
Such as Fig. 1, cut the invention discloses a kind of USB switching systems based on WiFi, including WiFi master controllers 10, USB
Switch 11, EUDM modules 12, WiFi antennas 13 and vehicle-mounted usb 14 are changed, WiFi master controllers 10 are connected with WiFi antennas 13,
WiFi master controllers 10 also switch switch 11 and are connected with EUDM modules 12 and vehicle-mounted usb 14 respectively by USB.
Wherein, the course of work of the switching system is：Master controller carries out data and music by antenna and external equipment
The transmission of file, realizes external equipment close to rear automatic connection transmission data and music file；
After vehicle-mounted USB interface is connected with the USB interface of in-vehicle player, main controller controls USB switchings are switched USB numbers
Vehicle-mounted USB mode is switched to according to passage, full automatic music playback function is realized；
When needing that music file is transferred into EUDM modules by external equipment, main controller controls USB switchings are switched USB
Data channel switches to EUDM template patterns, realizes the transmission and storage of music file.
The function that the system is realized is as follows：
1）Music file is managed
The music file in EUDM modules is carried out by outside mobile phone A PP to be increased, deleted and Classification Management；
2）Music file is transmitted automatically
The music file automatic synchronization in mobile phone is transferred in EUDM modules by WiFi wireless telecommunications；
3）The broadcasting of music file
The music file in EUMD modules is played out by the USB interface of vehicle-carrying music player.
The present invention can both realize the simple and convenience of USB flash disk music, can be wirelessly transferred skill by WiFi again
Art carries out direct management and the automatic synchronizing function of music file.
In the present embodiment, WiFi master controllers use MTK MT7628 WiFi chips, are wirelessly transferred and are switched
The work of the logical process such as switching；Use EUDM（Highly integrated FLASH modules and controller module）Module is deposited as music file
Storage is played out so that in-vehicle player is called.MT7628 chips are connected and communicate with EUDM intermodules using the interfaces of USB 2.0；
EUDM modules are realized directly may be used in MT7628 WiFi chips and in-vehicle player by switching switch using high-speed USB bus
Control only switches.
