Operation principle of the present invention does.
The present invention is made up of on-the-spot fire fighting truck Video Collection System, wireless system for transmitting data and supervision and management center three parts.
1, on-the-spot fire fighting truck Video Collection System.
The concrete condition of the destination that arrives according to fire fighting truck is installed corresponding video camera (colour or black and white, fixed or movable The Cloud Terrace, focus or zoom) and software systems on each fire fighting truck.One or several video cameras can be installed on each fire fighting truck, and each fire fighting truck respectively matees a Video Codec.Video camera is used for each control point real time video signals.The user can carry out level 360 degree to video camera, vertical 90 degree and zoom control.
Video encoder is the Network Video Transmission equipment that integrates functions such as sound, video acquisition, audio frequency and video compressed encoding, Network Transmission, WEB Server, input and output control.Video encoder can insert various simulation cameras, will simulate sound, vision signal converts the compression audio and video data streams into, goes up decoding and displaying or be reduced to TV signal through Video Decoder to PC through Network Transmission again to show.Video Codec among the present invention is responsible for being transformed into digital signal to the analog video signal of video camera; Compress also transmission of control signals in addition, the built-in 10/100M network interface card of Video Codec simultaneously; Be connected on the wireless device through netting twine; Monitor message after coding, the processed compressed is pooled to supervision and management center through wireless network, and the real time status of each control point can be seen by Surveillance center, and the monitor staff can pass through Surveillance center's local area network (LAN) or Internet remote live browsing video image.
For fully guaranteeing the bandwidth of each control point, adopt the coding standard of MPEG4, bandwidth occupancy is lower, and can realize the high-quality transmission and the storage of image, and transmission range is far away, is applicable to the monitoring of broad regions.
Also be provided with remote image monitoring terminal, GPS position indicator, phone on the fire fighting truck simultaneously, be used for communicating, and make the GPS position-finding with supervision and management center.
2, wireless transmitting system.
Adopt the point-to-multipoint mode to set up the no tape network that covers the monitoring field through the CDMA1X ip router.At remote monitoring point SCN2000 CDMA1X IP router (Ethernet interface) is installed.Product has long transmission distance, low time delay (very crucial to Video Applications) and the low characteristics of equipment cost, and efficient and economic video transmission solution can be provided.CDMA1X network theory speed 153.6Kbps, present actual test rate is 80kbps, surpasses the 56kbps that present common telephone dials up on the telephone, be average 30-40kbps the GPRS transfer of data 2-3 doubly.Can the live video information of different location be sent to Surveillance center through the wireless telecommunications means; H.263/ support is adopted, and the digital video frequency flow of form such as MPEG-1/2/4 reliablely and stablely transmits; Can guarantee that the stable of video flowing continues transmission, and not limited by complex-terrains such as mountains and rivers, river, bridge road.SCN2000 CDMA1X IP router device provides 10/100BaseT Ethernet interface, and the switch of control point, Video Decoder and video camera directly twisted-pair feeder are connected on the 10/100BaseT Ethernet interface of SCN2000 CDMA1X IP router.
3, supervision and management center.
Supervision and management center is responsible for receiving the video information of coming through the CDMA1X Network Transmission in each control point; Supervision and management center can show the image information of each on-site supervision point through televimonitor, also can carry out the image real-time monitoring through video wall, the video recording of the line number of going forward side by side sign indicating number; User login management; The coordination of control signal, video data can deposit DVR, the storage of recording a video, retrieval, playback, backup, recovery etc. simultaneously in.The monitor staff can be through the video recording of computer access storage server inquiry playback video.
Supervision and management center mainly is made up of Video Decoder, matrix video wall, monitoring server, DVR etc., can accomplish image scene and receive and demonstration, the storage of video recording, retrieval, playback, backup, recovery etc.
Video Decoder is handled the decoding video signal of the front end control point camera acquisition that sends through the CDMA1X network; Pass on the supervision and management center local area network (LAN) video monitoring server, be transmitted to each relevant departments or personnel's client again through switch through internal lan.
CDMA1X network theory speed 153.6Kbps, present actual test rate is 80kbps-90kbps, surpasses the 56kbps that present common telephone dials up on the telephone, be average 30-40kbps the GPRS transfer of data 2-3 doubly.Can the live video information of different location be sent to data center through the wireless telecommunications means; Support to adopt the digital video frequency flow of MPEG4 form; Reliablely and stablely transmit; Can guarantee that the stable of video flowing continues transmission, and not limited by complex-terrains such as mountains and rivers, river, bridge road.Be particularly suitable for the communication requirement of picture traffic intersection remote monitoring.
Data center is responsible for receiving the video information that each fire communication car is come through the CDMA1X Network Transmission.Data center can accomplish image scene and receive and demonstration, the storage of video recording, retrieval, playback, backup, recovery etc.
The invention has the advantages that.
1, the embedded hardware structure has been adopted at no CDMA remote image monitoring terminal, and stability, the reliability of system improve greatly; Simultaneously, can not receive virus harm yet.
2, system bulk is small and exquisite, compact, can be installed in arbitrary site easily, system power dissipation is low, can run without interruption throughout the year.
