Embodiment
As shown in drawings, the emergency commading system of wireless transmission video, voice, data, comprise and go out information gathering point before finishing on-the-spot video, voice, data acquisition some, go out the emergency command platform of video that information gathering point sends, voice, data message before the reception, wherein:
Go out before described to be provided with between information gathering point and the described emergency command platform going out the wireless bridge that information that information gathering point collects is sent to described emergency command platform before described;
Go out information gathering point before described and comprise video acquisition device, voice acquisition device, data acquisition unit, the switch of the information aggregating that described video acquisition device, voice acquisition device, data acquisition unit are obtained, the wireless bridge that the information of switch is sent; The video encoder that described video acquisition device comprises camera, the image of camera picked-up is encoded; The audio coder that the voice signal that described voice acquisition device comprises microphone, obtain microphone is encoded;
Described emergency command platform comprises the wireless bridge of reception information, with the information block of wireless bridge is the switch of video, voice, data message, respectively desampler video, voice, the video play device of data message, voice playing device, data replay apparatus; Described video play device comprises the Video Decoder that the video information of switch is decoded, the monitor that the information of Video Decoder is shown; The loud speaker that voice playing device comprises audio decoder, the signal of audio decoder output is play;
The video that the utility model mainly arrives collection in worksite, voice, data are sent to the emergency command platform by wireless bridge, employing is based on up-to-date metropolitan area network standard IEEE 806.16a Fast Ethernet bridge, the Fast Ethernet bridge is operated in the 5.8GHz frequency range, support point-to-point and network configuration point-to-multipoint, aerial speed is up to 720Bbit/s, communication distance can reach 50Km farthest, can satisfy image fully, voice, the transmission requirement of data, owing to adopt dedicated encrypted technology and multiple modulation system to select signal, it is strong to have an antijamming capability, the advantage of strong security and good stability.The utility model has merged wireless access and backbone network linkage function, can carry out telemanagement by the web interface, and advanced person's MPEG-4 video compression technology is combined with the VOIP technology, has realized the high-speed radio transmission of video, voice, data.The utility model information of carrying out sends and the wireless bridge of acceptance is selected the AN50 system for use, be operated in 5.8GHz, adopt Orthodoxy Frequency Division Multiplex (OFDM) technology, can utilize a plurality of carrier signals to finish the transmission and the reception of information, has the bidirectional self-adaptive modulation capability, can be in eight kinds of modulation systems (from BPSK to 65QAM) regulate radio link quality according to incoming level and signal to noise ratio automatically successively, aerial speed is up to 72Mbit/s, thereby guaranteed the highest and the most steady data throughout.The emergency command platform adopts 90 ° of speed to antenna, and transfer point is selected omnidirectional antenna for use, avoids the influence of barrier to the signal transmission, makes signal arrive wireless network by optimal transmission paths, realizes the free of discontinuities transmission with wireless network.
The emergency commading system of described wireless transmission video, voice, data carries out transform coding, compression processing with the image information of camera picked-up by video encoder, switch, data transmission after will being handled by wireless bridge is given the emergency command platform, after the wireless bridge of emergency command platform receives information, with information be sent to switch successively, Video Decoder decompresses, decodes, again image is sent to monitor and shows.Because wireless transmission channel limited bandwidth, in order to improve channel utilization, the image-based band signal is adopted the video compression technology that meets the MPEG-4 compression standard, reduce signal bandwidth, save Radio Resource, adopt the technical grade video encoder product of Chinese promise to finish analog-to-digital conversion and compression, and employing MPEG-4 coded system, guarantee high rate data transmission, by coaxial cable, the front end camera is sent to video encoder with video image with analog form.
Mobile video point-to-multipoint Video transmission system adopts comparatively leading in the world at present Orthodoxy Frequency Division Multiplex (OFDM) technology, the OFDM modulation technique becomes channel distribution the subchannel of some quadratures, greatly improved the availability of frequency spectrum, strengthened the ability of anti-narrow band interference, non-intervisibility such as be adapted in the city, outskirts of a town, building and have using in the environment that stops, show remarkable " diffraction " and " penetrate " ability, and the stability of transmission under the high-speed motion state.Can resist the interference between signal waveform effectively, when in the channel because when multipath transmission and the decline of frequency of occurrences selectivity, the subcarrier that only drops on the frequency band recess with and the information of carrying influenced, other subcarrier does not suffer damage, so the total bit error rate performance of system is far better.By the combined coding of each subcarrier, have very strong asthenia ability, systematic function is improved.
The voice signal that voice acquisition device obtains microphone is encoded by audio coder and is sent to switch and is connected with wireless bridge and sends, and the wireless bridge of emergency command platform is sent to voice playing device with the voice signal of reception by switch.Audio decoder is decoded signal, is exported by loud speaker at last.Voice device adopts the VOIP technology, go out transfer point and maneuvering platform voice call function before the realization, maneuvering platform packet network and inner exchanging system fixed network can also be coupled together, realize the conversation between IP phone and the landline telephone, voice device meets H.323.SIP system protocol standard, support FXS, FXO interface, insert fixed network, realize the communication of IP phone inside on emergency command platform and the camera point that before goes out information gathering point by described interface.
Data transmit and can link to each other with the 100M network switch by the 100M Ethernet interface, are sent to wireless bridge again by switch and send and accept.
