The built-in embedded-type ARM 946S-E processor cores of 88W8510, high multidiameter delay expansion is tolerant, built-in aerial adopts diversity receiving technology, encrypt and CCM authentification of message built in hardware crypto engine for WEP and 80211i AES, support 802.11e QoS quality services to guarantee, can match MII or PCI external interface, integrated 10/100M Fast Ethernet MAC and the phy interface that adopts the VCT technology, support the 802.1X safety mouthful agreement of advanced secure authentication special use, 256 pin TFBGA encapsulation, package dimension is 17mm * 17mm only.
The advantage of 88W8510 is a lot, and it is the 802.11g solution, compatible 802.11b agreement of while, and range of receiving is large, and it is good to connect robustness, has reduced losing of information; The transmitting-receiving performance is good, scope is large; On the basis of low power dissipation design, integrated function as much as possible and performance boost; Can connect simultaneously more wireless terminal, need not to reduce wireless throughput performance; The data that can guarantee to transmit, audio frequency, video data continuous and stable; Can external many mouthfuls of routers and external system bus; Reduced Material Cost and the stube cable method for diagnosing faults is provided; Be to improve the security under public environment, added more authentication mechanism; Use AP and the gateway chip of 802.11b agreement in the pin compatibility Marvell product, make things convenient for the switching between 802.11b and 802.11g.
The application has adopted 88W8510WIFI chip module and Traditional IP camera, has realized the wireless transformation of camera.Through actual test, wireless IP camera can be realized errorless code communication in the 20MHz scope, and transmission of video images is superior in quality, stable, flexible.Compare other camera design proposals, this programme tool also has the advantages such as low-cost (no matter being communications cost or hardware cost), low-power consumption, is a kind of design that economy and technological value are relatively arranged.
In the data handling component, the video control software that message handler 2 adopts mainly is to adopt the motion of PELCO-D/P agreement control The Cloud Terrace.
In the utility model, utilize the wireless bridge technology, a plurality of monitoring points and CCC can be coupled together, and build rapidly, can within the shortest time, set up rapidly wireless network links, the wireless bridging technology is to utilize a pair of wireless bridge, the network connection of two separation is got up, and carry out data transmission by wireless bridge.
The high network bandwidth of the 11Mbps/54Mbps that wired link can reach can guarantee the stable transmission that continues of video flowing fully.Use wireless bridge, do not have the worry of wiring, do not destroy original environmental facility, short construction period, cost performance is high, and extendibility is strong, as long as increase or reduce the wireless bridge of monitored point, just can finish increase or the minimizing of monitored point.In the situation of condition license, utilize wireless bridge can support farthest bridge joint more than 50 kilometers.Radio network product support 11,22/54Mbps and the higher network bandwidth of IEEE802.11b/g/a can guarantee to adopt fully and H.263/MPEG-1/2/4 wait the digital video frequency flow of form reliablely and stablely to transmit, and reach the purpose of wireless video monitoring.
In the utility model, detection components 1 provides three kinds of video cameras, is respectively:
Adjustable for height everything rotates night viewing camera 11, and this mode of inspecting is to adopt the stepless height-regulating insulating support as bracing frame, and wireless camera (anti-electric field interference performance is strong) is installed on the top.The implementation method of stepless height-regulating insulating support: frame bottom adopts the scalable three-legged support of metal, be convenient to firmly wireless camera be stood aloft with its weight, be unlikely to topple over, one side is installed a hand rolling wheel at the top of metal tripod pipe core, this hand rolling wheel is the key point of stepless height-regulating insulating support, can be along with the height that shakes random adjusting insulating support rod (the namely height of wireless camera); The rubber plastic pipe that 2 internal-and external diameters cooperate is installed in the A-frame pipe core, prop up weighing lever and tripod in order to isolated insulation, guarantee good dielectric strength, built-in plastic tube one side two ends respectively stay 8 centimeters to open a groove, this groove is convenient to the motion of elevating control insulating cord, reduce friction the good descending operation effect of light, safe arrival; An insulating bar is installed in inside at interior plastic tube, the internal diameter of its external diameter and plastic tube cooperates suitably, at the bottom of insulating bar one side perforating, one end of insulating cord is fixed in the bottom of insulating bar, the insulating cord other end is fixed on the rolling wheel by hand rolling wheel by interior plastic tube side channel, thereby reach the lifting of insulating bar, a metal connector is installed on top at insulating bar, be used for connecting another insulating bar, such mode can be regulated insulating bar and highly the highlyest can be reached 5M, the insulating bar two ends of every adjunction are equipped with metal male and female web member, insulating bar insulation bearing strength is 110kV, can solve the work of inspecting for eminence, for example as the rheology bottom, the general video camera such as main transformer top or the camera situation of can not completely clearly information being made a video recording, can guarantee like this information safety and comprehensive, also can not cause discharge dangerous even without enough safe distances like this;
Snakelike video camera 13, this inspects function because the space that need to enter is very little, therefore also very little for the volume requirement of video camera, the general this mode of inspecting all is to carry out in without electricity, consider directly to adopt the snakelike video camera 13 of gastroscope formula to link to each other with portable computer, form whole viewing instrument and enter additional space collection relevant information, for example: in the switch cubicle, in the narrow and small cabinet;
The video camera 12 of can walking, in cable duct, the hole, personnel's inconvenience enters or distance long place again, adopts the wireless remote control robot camera.Embodiment is: the part of advancing adopts high-quality wireless remote control dolly, the video camera that can turn to up and down is installed at this dolly, video camera has the night vision shoot function, and at dolly installation tyre light source, the computer background control system is adopted in the remote control of video camera, and independent telepilot is adopted in the control of dolly, is a marline at the dolly rear portion, prevent that dolly from blocking in advancing, thereby guarantee that shooting information is clear.
4, protection of instrumentation: totally be divided into two parts, first is the video camera guard box, and second portion is tripod and insulating bar protection putting bag.
More than a kind of detection system provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
