Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is the internal frame diagram of main frame of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the utility model is made up of liquid crystal panel, main frame and Reverse Sensor back-sight visual system three parts.
Liquid crystal panel is made up of LCDs, button, remote control head and two-way Microphone for karaoke input interface.Liquid crystal adopts 5 to 9 cun screens.Button comprises that power supply, rotation fly the shuttle key, stop/cancellation, DVD/VCD, MP3, FM/AM, image switching, microphone, quiet, left and right acoustic channels switchings, F.F./1, rewind down/2, the preceding paragraph/3, next section/4, time-out/5, stop/6, setting, function key.Native system provides the graphical user operation interface easier user's operation.
Main frame is the core main part of native system, is responsible for looking the encoding and decoding of audio frequency and the processing of various affairs.Main frame comprises two parallel C PU, video IO interface, network interface, USB interface, GPS module, GPRS module, power amplifier, radio receiver, TV-set receiving module and hard disk.Hard disk adopts common hard disk, adopts movable design and locking protection on the structure, can directly extract the renewal that hard disk carries out program after the user unblanks.Main frame and front panel carry out communication by universal serial bus.
The Reverse Sensor back-sight visual system is mainly handled the range finding and the stack of following video of radar.Comprise rearview camera, radar ranging module and video superimpose module.The radar back-sight visual system is finished the distance detecting of barrier during backing and range information is added on the backsight video.The radar back-sight visual system can be according to the information reminding driver reversing with sound and video of the distance of obstacle distance.After driver's reverse hung up, main frame detected automatically and the superposed signal of backsight is delivered to liquid crystal panel and shows.
As shown in Figure 2, be the internal frame diagram of core main frame of the present utility model
Motherboard adopts the distributed system design, adopts two parallel C PU (PNX1302) to carry out the processing of affairs, is used for handling the decoding of DVD constant pitch purpose from CPU, and host CPU is handled video recording and looked the coding of audio frequency and manage all things that are outside the scope of one's own job affairs.Main frame can be finished the broadcast and compression and the record of looking audio frequency of image and sound program simultaneously.Operating system adopts the pSOS distributed real time operating system.
The utility model is by carrying out software decode from CPU to various multimedia files.The file that comprises DVD, VCD, MP3, MPEG4 video file and Divx form.And can support more codec format by the mode of software upgrading.
