Embodiment
The utility model will be further described below in conjunction with the example in the accompanying drawing:
Shown in Figure 1: as at first by image capture module and audio collection module image and the sound that collects to be sent to the multimedia audio-video processor module, processing module carries out that De-interlace pre-treatment, OSD overlap-add procedure, contrast draw high, color enhancement is processed etc. and to be processed, then will process to such an extent that image carries out H.264 compressed encoding processing, be sent to network by the WIFI wireless module again, be sent to the control room through wireless Ethernet.The mine lamp user can carry out two-way speech talkback by audio input device and integrated dispatch chamber, and the control room can real time inspection to the ambient conditions of mine lamp user position.Simultaneously videograph the time at that time.The integrated dispatch chamber can be carried out the relevant parameter of the videos such as brightness, contrast, colourity by network and be arranged to video camera.
Shown in Figure 2: multimedia audio-video processing module schematic block diagram, master chip uses the high-performance video coding chip HI3512 of Hai Si, use this chips two DDR2 memory grains of must arranging in pairs or groups, total internal memory is up to 256MB, that use is Hynix memory grain HY5PS1G1631CLFP_Y5, has guaranteed that it is required a large amount of exchanges data buffer memory that HI3512 processes.That pin-saving chip uses is S29GL064M90TAIR4, the norflash of 8MB, storage inside whole system start required UBOOT file, linux system kernel file, Linux file system, the softwares such as Linux application program.The required peripheral crystal oscillator of the multimedia audio-video processing module is simultaneously integrated HI3512, reset and with are connected the various interface that module connects.
Shown in Figure 3: the image capture module circuit diagram.Image collection chip adopts the image collection chip OV7725 of OmniVision company, require to design the form that interface also made required data wire by peripheral circuit according to OV7725 official, be respectively HS (line frequency signal), VS (field frequency signal), PCLK (data clock signal), D0～D8 (8 bit data signal), I2C signal (chip controls signal) picks out by the FPC interface these signals and one group of 3.3V power supply with signal.
Shown in Figure 4: the audio-frequency module circuit diagram.Audio-frequency module adopts the chip TLV320AIC31IRHBR of TI, and master chip HI3512 carries out the mutual of data by I2S and TLV320AIC31IRHBR, by the I2C bus TLV320AIC31IRHBR is controlled.In the two-way voice talkback process of whole system, the simulated audio signal that TLV320AIC31IRHBR gathers by MIC is processed by inner AD and is converted to digital signal, then transfer to HI3512 by I2S, HI3512 with these Signal codings after by wireless network transmissions to the integrated dispatch chamber.After HI3512 obtains the digital audio and video signals decoding of integrated dispatch chamber by Internet Transmission simultaneously, the data message of decoding is transferred to TLV320AIC31IRHBR by I2S, and the TLV320AIC31IRHBR again DA by inside processes and signal is become analog signal broadcasts by headset after amplifying.
