Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, wireless control system in a kind of car based on DLNA, comprise automobile bus 10 and adopt in the car of DLNA protocol stack 5 access networks that navigation amusement establishes 1, personal consumption electronic equipment and router four.
Wherein, personal consumption electronic equipment comprises household consumption electronic equipment 3 and mobile consumer-elcetronics devices 2, and router is can be simultaneously or connect separately the router four of Wi-fi and Ethernet.Household consumption electronic equipment 3 is generally home media center etc., be connected with the amusement equipment 1 that navigate in car by router four, and mobile consumer-elcetronics devices 2 is generally smart mobile phone, panel computer etc., can, with household consumption equipment 3 equally by being connected with the amusement equipment 1 that navigate in car in the mode of Wi-fi or Ethernet with router four, also can carry out point to point connect by the amusement equipment 1 that navigate in the mode of Wi-Fi Direct or ad-hoc and car.
In car, navigation amusement equipment 1 are as DLNA controlled in wireless gateway, be connected with automobile bus 10, comprise control message resolver 6, automobile bus interface 7, navigation amusement function control interface 8 and DMR and DMS interface 9, can use DMR interface and DMS interface simultaneously or only use one of them according to different demands.In the time realizing controlled in wireless, the control information that personal consumption electronic equipment sends adopts DLNA protocol stack to be forwarded in control message resolver 6, to carry out dissection process.Then, this control message resolver 6 calls automobile bus interface, navigation amusement function control interface, DMR or the control of DMS Interface realization to in-vehicle device according to the content of control information.
In the time that the function of required realization belongs to other functional modules that are connected on automobile bus, automobile bus control message is translated in the control information that control message resolver 6 is responsible for handle, and by calling automobile bus protocol stack interface 7, the control message after translation is sent to corresponding function module through automobile bus.
When the function of required realization belongs to while navigating amusement equipment 1 in car, control message resolver 6 calls navigation amusement function control interface 8, and this interface is responsible for starting corresponding navigation amusement function.
In the time that the function of required realization belongs to the controlling media play of standard DLNA protocol definition, control message resolver 6 calls DMR or/and DMS interface 9, this interface is responsible for starting corresponding DLNA function, this operation while having comprised DMR playing stream media of this function, for example play/suspend, skip forward/back and a media file of up/down etc., and browse, select and push the media file of storing in DMS.
Equipment of the present invention can connect i.e. use, and in the time that new equipment adds network, this equipment can be informed the DLNA function that it is realized, the information such as media formats and digital publishing rights of support to other equipment in network by DLNA protocol stack.In like manner, in the time having equipment deviated from network, also can inform this information to other equipment in local area network (LAN).
In addition, the present invention can realize the interior controlled in wireless security level authentication of car flexibly.For example, in the time stopping, can realize all navigation amusement operations; Vehicle Speed be greater than 30 kilometers/time, forbid that the video playback that the operation of all car doors/window is relevant with navigation screen operates; In the time of 4S shop, can carry out all vehicle body operations etc.
