Embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete execution mode according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, vehicle-mounted high-definition The Cloud Terrace system is by the vehicle-mounted digital high-definition tripod, and is used for controlling the vehicle-mounted digital high-definition tripod, receives, the vehicle-mounted high-definition embedded host of uploaded videos signal forms.The vehicle-mounted digital high-definition tripod is installed in the roof place, it is by holder shield, and built-in high power, the high-definition digital video camera that remote, induction is infrared form, be provided with windowpane on holder shield, rain brush is set in the windowpane outside, in the windowpane inboard, heating tube is set, and fan, rain brush, heating tube and fan form parallel circuits, and are connected with temperature relay.
Be provided with vehicle-mounted NVR video storage device, GPS module, cradle head control module, 3G module and WIFI module in the vehicle-mounted high-definition embedded host, vehicle-mounted NVR video storage device, 3G module, WIFI module are connected with the HI352X chip by video interface, and GPS module, cradle head control module are connected with the HI352X chip by the UART interface.The vehicle-mounted high-definition embedded host carries out wireless network by 3G module, WIFI module and digital supervision center and is connected.
When ambient temperature was too high, the fan in holder shield can be opened automatically, blew coolingly, also can carry out corresponding heat tracing when temperature is low, guaranteed that the high-definition digital video camera is carrying out work in normal temperature range.When rainy, can by artificial cradle head control, brush the rain operation to the glass of holder shield.During low temperature, when frost appears in holder shield, can heat defrosting in the winter time.
Surveillance center arranges registrar, load-balanced server, Streaming Media forwarding server.By being arranged on the corresponding reception software for display in the cradle head control module, realize that the video of Surveillance center shows, vehicle location information, the monitoring of the situations such as communication.
The built-in relevant control software of cradle head control module, in order to whether to control the work of vehicle-mounted digital high-definition tripod, and can realize following functions: (1) video displaying live view: the video image that the displaying live view vehicle is uploaded, the parameters such as video image resolution, code stream, frame per second, picture quality are adjustable in real time, video is uploaded and is postponed less than 5 seconds, network enabled bandwidth self-adaption function.(2) long-range grabgraf and rear end recording function: support client grabgraf button, crawl high definition photo can be adjusted photo resolution, picture quality in real time.For important video data, can record a video when supervising is kept at above computer.(3) vehicle location management function: support the GPS locating information to forward, and show track of vehicle (time, place, longitude, latitude, speed) on map, historical track calls playback function, capable of dynamic playback vehicle driving trace.(4) remote alarming function: support multiple warning function and real-time display alarm information on platform.Hand push button is reported to the police: support artificial hand push button to report to the police; Cross the border warning, overspeed alarming, obstruction reported to the police: can judge vehicle running state by GPS information, whether vehicle exceeds the speed limit, whether crosses the border, whether stops for a long time in a place (needing customized); The equipment warning that makes mistakes: the support equipment self check is reported to the police and is uploaded, and is illegally cut off as vision signal.(5) vehicle management function: the user manages by information such as associated vehicle type, fleet, car plate, contact persons.Such as functions such as vehicle title, fleet's title, Pilot Name, driver's phone, obstruction time of fire alarming, vehicle maximal raties.And can independently divide into groups the single passage of each car by demand.(6) log recording function: various operation log recordings, and can inquire about by the time period.(7) local playing back videos function: the video recording that the front end net passes can carry out this locality by playout software to be play, and supports the multichannel playback function.
The HI352X chip is the high-end SOC chip of a specialty for multichannel D1 and multi-path high-definition DVR, NVR, the application and development of HVR product.
vehicle-mounted NVR video storage device is made of video storaging equipment, function is mainly the video image of vehicle-mounted digital high-definition tripod collection to be carried out the storage of this locality, carry out the local video coding, transmission for video information, do the processing of image information, the audio/video information of Vehicular video acquisition terminal collection site, with the compressible one-tenth JPEG of data, MPEG-4 and H.264 wait form, then economy-combat is sealed dress and is sent to the wireless-transmission network module, can carry out simultaneously long-range monitoring, also has the playback function of image etc., can constantly grasp the on-the-spot situation of law enforcement, for law enforcement provides foundation, this device is prior art.
The GPS module adopts the Embedded GPS module, integrated high u-blox the 5th generation GPS engine of present cost performance.It possesses-signal sensitivity of 144dBm, and extremely low power consumption (120mW), the UART Interface design of small size (43.1X25.5X14mm) and 4 pins makes this module to be applied to very easily in various embedded products and mobile terminal.
3G network is according to all parts of the country condition difference of arranging net, and signal strength signal intensity is different, and even some place does not have 3G network, through understanding take Beijing as example: all right in 5 rings, as not necessarily stable to effect district signal, must the actual measurement understanding.Good and bad and in the range of application in the world and in the applicable cases of China by three large standards of three large operators relatively, find that the net of domestic telecommunication is relatively good, secondly UNICOM, be to move again.And produce in the manufacturer of 3G, in emerging, Huawei in stability, the aspects such as model quantity, technical support, buying.Promotion efficiency is larger.Through relatively, finally adopt Huawei or in the 3G module of emerging telecommunications standard.
The WIFI module adopts integrated microcontroller (MCU) and 802.11 b/g 2.4GHz radio transceiver chips to be integrated.
Video interface adopts the HDMI interface, and the data transfer bandwidth up to 5Gbps can be provided, and can transmit audio signal and high definition video signal without compression.
UART is a kind of general serial data/address bus, is used for asynchronous communication.
The high-definition digital video camera adopts the high-quality HD cmos sensor of 2,000,000 pixels, realizes the high-definition digital image, and resolution reaches as high as (1280 * 960) high-resolution qualitative picture.Support Windows Mobile, Symbian, iPhone platform intelligent mobile phone to supervise, support that IE directly browses, night visual range is greater than 120 meters, camera lens rain brush and defrosting function, and the definition of 1080P can reach the broadcast level image quality.Support the real-time dual code stream coding of 720P+720P, the assurance of reliable high-definition image is provided for vehicle-mounted monitoring.
Above technical characterictic has consisted of most preferred embodiment of the present utility model, can increase and decrease inessential technical characterictic of the present utility model according to actual conditions, to satisfy actual needs.
