Description of drawings
Fig. 1 is the topology diagram of the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but the embodiment of the utility model is not limited thereto.
Embodiment
As shown in Figure 1, the intelligent long-range safety defense monitoring system that the utility model is used for the offshore wind generating group comprises some groups of video cameras, some access-layer switch and master-control room; Some access-layer switch are installed in respectively on some typhoon machines, and promptly every typhoon machine is provided with an access-layer switch; Some groups of video cameras are installed in respectively on some typhoon machines, and promptly every typhoon machine is provided with one group of video camera, and video camera is connected with access-layer switch through the UTP twisted-pair feeder.Access-layer switch is connected with the wind energy turbine set Ethernet through the blower fan internal lan, is connected to master-control room through the master-control room internal lan again.Master-control room comprises core switch, and the IPSAN storer, streaming media server, management server, decoding server and the display that are connected with core switch respectively, and wherein display is a video wall.
Every group of video camera has 5 video cameras; It is that the separate unit blower fan is adorned 5 video cameras altogether: one 1,000,000 high definition web camera of installing in every typhoon machine pylon porch; Video camera band cloud platform and have zoom function is used to keep watch on the real-time condition that blower fan outside and personnel pass in and out blower fan; One 1,000,000 high definition web camera of installing in the cabin, video camera band cloud platform and have zoom function is used for from a distant place through comprising the operation conditions of equipment such as regulator cubicle, Hydraulic Station in the camera surveillance cabin; One 1,000,000 high definition web camera of knob cable place installing in pylon, video camera band cloud platform and have zoom function is used to keep watch on the real-time condition of knob cable.Installing one station symbol clear web camera in column foot, video camera band cloud platform and have zoom function be used to keep watch on the state of column foot cabinet and transformer etc., and the cooperation fire-fighting system is protected to it; Install the clear video camera of a station symbol in nacelle top, video camera band cloud platform and have zoom function can be used for keeping watch on the ruuning situation of the blade of blower fan in the distance under the zoom situation.
The main image absorption of system front end collection equipment is meant video camera.Video camera is as the image capture device of video monitoring system, and the quality of the picture quality that it obtained will directly have influence on the quality of coded image, and then has influence on the picture quality that finally appears in Surveillance center.The acquisition mode that adds video encoder with the conventional analogue shooting compares, and the application of current network video camera has advantage more: data source is the full digital processing signal, no analog transmission process; Antijamming capability is strong; Sharpness is higher, only needs a netting twine to connect up, and is easy for installation.
In the utility model; Because offshore wind turbine has a very wide distribution; According to the specific position of wind-powered electricity generation unit and master-control room, the pattern of network using three-tier architecture: Access Layer, convergence-level and core layer, Access Layer are provided with the access-layer switch that is connected with the Surveillance center switch.Adopt the 100M network to accomplish the access of leading portion video at Access Layer, convergence-level and core layer then all adopt the 1000M network, realize converging, store and managing of all leading portion videos by them.
The video recording in real time in 24 hours of every video camera, one day calculation of capacity formula of storage are:
Capacity (GB)=way * code stream (Mbps) * 3600 second * 24 hours ÷ 8 ÷ 1024
In the present embodiment, the about 2Mbps of the code stream of SD web camera, the about 4Mbps of the code stream of high definition web camera for separate unit video camera memory capacity computing formula is:
Single channel SD memory capacity=1 tunnel * 2Mbps * 3600 second * 24 hours ÷ 8 ÷ 1024 ≈ 21GB
Single channel high definition memory capacity=1 tunnel * 4Mbps * 3600 second * 24 hours ÷ 8 ÷ 1024 ≈ 42GB
Calculate with the separate unit blower fan in the utility model; 2 of total SD web cameras; 3 of high definition web cameras; The false wind electric field has 10 typhoon power generator groups, and every of the network storage server that then adopts can be stored 64 road high clear video image data at most, according to average every be responsible for storage 50 tunnel, storage was calculated required storage total amount in 30 days and is:
SD memory capacity (TB)=way * single channel memory capacity * fate ÷ 1024
=20 tunnel * 21G * 30 ÷ 1024
≈12.3（TB）
≈13（TB）
High definition memory capacity (TB)=way * single channel memory capacity * fate ÷ 1024
=30 tunnel * 42G * 30 ÷ 1024
≈36.9（TB）
≈37（TB）
In sum, the needs according to system dispose: 1 of storage server needs 50TB memory capacity altogether; Then memory capacity is 25 2TB hard disks, in addition, considers the stability of system and the consideration of system redundancy; 27 hard disks of storage server configuration then amount to the 54TB hard-disk capacity.
Because the supervisory system networking structure is day by day complicated,, need carries out unified management through software platform to the video data that comes from front-end collection and handle at the master-control room of total system.The physical support of platform is management server, streaming media server, decoding server, client software etc.For guarantee wind field to the video in all blower fans realize local to 30 days with the interior inquiry of whenever recording a video, playback; Guarantee simultaneously important video file can store the longer time; So in the utility model, master-control room carries out storage and uniform through advanced person's IPSAN storer.Arrange 1 streaming media server at master-control room, be used for the front end video image is transmitted, give simultaneously and divide control end, demoder that video is provided, reduced the pressure of access to netwoks.And the unified management through decoding server; Export display with the hard decoder mode from the video code flow decoding that front end obtains with demoder; So master-control room is arranged 1 demoder and display (be used to retrieve for examination institute's supervision blower fan, also can adopt the mode that can go up wall).
Nacelle top: on the survey wind mast of cabin afterbody, install and fix a The Cloud Terrace support through pipe clamp, a clipping the ball video camera is installed on the The Cloud Terrace, camera lens is mended dress LED white light, and video camera is installed can see under the zoom situation that whole blade is as the criterion.
The cabin elbow: install and fix a The Cloud Terrace support through pipe clamp, a clipping the ball video camera is installed on the The Cloud Terrace, camera lens is mended dress LED white light, and acoustic pickup is installed, and video camera installation visual angle does not have the dead angle with engine room inside and is as the criterion.
The cable layer is turned round in driftage: install and fix a The Cloud Terrace support through pipe clamp, a clipping the ball video camera is installed on the The Cloud Terrace, camera lens is mended dress LED white light, and acoustic pickup is installed, and it is benchmark that video camera is installed can keep watch on blower fan knob cable cable machinery.
Column foot: column foot becomes, column foot cabinet layer installs and fixes a The Cloud Terrace support through pipe clamp, and a clipping the ball video camera is installed on the The Cloud Terrace, and camera lens is mended dress LED white light, and acoustic pickup is installed, and is used to keep watch on column foot change, frequency conversion tank etc.Video camera is installed panorama supervision column foot cabinet external circumstances being as the criterion, and cooperates fire-fighting system that the column foot cabinet is protected with this.
