Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
A kind of wireless audio and video supervisory control system comprises audio-video collection assembly 1, wireless launcher 2, wireless receiver 3, data collecting card 4, wireless router 6, home server 5 and remote monitoring assembly 7.
Audio-video collection assembly 1 comprises four groups of cameras and microphone, and the geographical information collection equipment that is provided with the battery pack of supplying power when being used for operation out of doors and gathers current geographic position information, and audio-video collection assembly 1 is carried by the operating personnel.Camera is according to the difference of photo-sensitive cell, and camera is divided into CMOS camera and CCD camera two big classes.CCD and CMOS utilize light sensitive diode (Photodiode) to carry out opto-electronic conversion, and the light of reception is stronger, electric charge is many more; Light more a little less than, electric charge is few more.In this way, the scenery of taking is transformed into carries the different a plurality of pixels of amount of charge.The main distinction of CCD and CMOS is the different of data amplification and transmission sequence.After exposure, CCD imports the electric charge of each pixel generation of each row in the buffering area in order, and unification is amplified by amplifier, converts digital signal output then together to; And each pixel side of CMOS is all connecting an amplification converter, amplifies and be transformed into digital signal to the signal of each pixel, at last output in the lump.With respect to CCD, though the cost of CMOS is little, power consumption is low; But, CMOS all comprised amplification and change-over circuit because going up each pixel; The area of single photosensitive regions of pixels is littler than CCD, and each pixel of CMOS will amplify separately, so the photosensitivity of CMOS is lower than CCD; Be difficult to reach all pixels simultaneously and amplify synchronous effect, image effect is poorer than CCD.Because the site operation environment is comparatively abominable, can cause certain influence to the use of electronic equipments such as computer, the reliability of slave unit is set out, and the present invention adopts the camera of CCD photo-sensitive cell.Can also be provided for the The Cloud Terrace of controls lens direction as required on the camera.
It is the data collecting card of TD3104 USB DVR that data collecting card in the present embodiment adopts model, and this capture card is provided with 4 road acquisition channels, the audio, video data that corresponding four groups of cameras and microphone collect; Adopt the coded system of MPEG-4 that audio/video information is compressed; And the stored in file format that adopts AVI wherein when writing audio stream, has been carried out Synchronous Processing at home server 5; Adopt the timestamp technology in the program, audio, video data is indicated.Under normal conditions, in the processing to the audio-visual synchronization problem, often be as the criterion,, can guarantee the continuity of auditory effect like this because people will surpass the sensitiveness of video data for the sensitiveness of voice data with voice data.Consider the application characteristic of video monitoring system, the information that video signal comprised is more important than audio frequency, so be benchmark with the video data in the reality.So-called timestamp technology; Promptly be to give each audio and video data streams joining day mark, writing the audio compression bag before the avi file, the time difference that should calculate audio pack and video packets in when packing; Data for time mark differs bigger are given up; Otherwise, this audio pack is write avi file, to guarantee last audio-visual synchronization.
In order to realize remote monitoring; Need the audio-video document of home server 5 be sent on the remote monitoring assembly 7; Here adopt typical client/server (C/S) pattern, the data of whole system transmission have control data, comprising: the control command of The Cloud Terrace motor-driven lens; Video recording parameter, system parameters, control data requires to accomplish accurate transmission; And the geographical location information of audio/video information and camera, the data volume of these data is big, allow to have certain data loss rate in the transmission, but real-time requires height.Therefore adopt the ICP/IP protocol transmitting control data, adopt the geographical location information of udp protocol transmission tone video information and camera.
In order to observe the position and the operating state of camera more intuitively; Native system is provided with the electronic map positioning function; Home server 5 can generate electronic chart according to the geographical location information that audio-video collection assembly 1 sends, and the position of audio-video collection assembly 1 is accurately located.
The course of work of native system is: after audio-video collection assembly 1 collects audio/video information; Synchronous transmission to data collecting card 4; 4 pairs of audio/video informations of data collecting card compress and are stored on the home server 5, when remote monitoring assembly 7 need carry out remote monitoring, behind 5 pairs of audio/video information decompress(ion)s of home server; Be sent to remote monitoring assembly 7 through wireless router 6, wherein remote supervisory and control(ling) equipment can be various electric terminal equipments such as computer, PDA and mobile phone.
The present invention, reduces accident risk and in accident the back takes place and offer help for the accident identification to improve the intuitive of work high above the ground through the audio/video information of remote collection work high above the ground process.
