The monitoring device comprises a camera at a front end, network equipment, and an information processing center at a rear end, wherein the camera is provided with an optical fiber interface, the network equipment is an optical switch, and the camera and the optical switch are connected via an optical fiber composite low voltage cable. The camera and the optical switch are connected via the optical fiber composite low voltage cable, which integrates optical fiber, power transmission copper wire, and copper signal wire pair, i.e. optical cable and power line are integrated, thus individual power supply line is not needed, wiring is simple, construction amount is small, and cost is low.
Description
Technical field
The utility model relates to the industrial technology field, particularly a kind of supervising device of electric power system.
Background technology
The supervising device of electric power system, it is closed-circuit TV system, be widely used in the electric power supervisory control field, can realize collection, reception, transmission, the processing of video image, and can with other as patrol and examine, system such as gate inhibition links, accomplish displaying live view, centralized management, efficient control, in time find.
The front-end camera of traditional closed-circuit TV system mainly divides two kinds:
1. analog video camera.The video data of this type of camera acquisition is connected DVR (DVR, Digital Vedio Recorder) or video server (DVS, Digital Vedio Server) with control data by video line with control line.Such video camera can not reach the high definition grade usually.And video data must enter DVR or DVS by analog video line transmission, goes into the network transmission through decoding is laggard, and video camera comes power taking by independent a pair of power line.
2. network digital camera.This type of video camera directly is connected with video main station system or monitor client by netting twine.This class video camera generally can reach the high definition grade, does not also need the decoding through DVR or DVS, directly is connected by netting twine between video camera and the switch.But video camera must be by a pair of independent power line power taking.
In sum, the front-end camera of traditional closed-circuit TV system needs 1 pair of power line and 1 group of data wire (netting twine or video line+control line) ability operate as normal at least.Often need position, up to a hundred control points and dispose a cover closed-circuit TV system in power plant, each corresponding video camera in some position, every video camera needs 2-3 to cable, add power plant's complex structure, cause the complexity that often connects up when disposing closed-circuit TV system, great in constructing amount, the cost height.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of supervising device that need not independent power line, wiring is simple, construction volume is little, cost is low electric power system.
The technical scheme that addresses the above problem is: the supervising device of this electric power system, the information processing centre that comprises video camera, the network equipment and the rear end of front end, video camera has optical fiber interface, the network equipment is an optical switch, video camera and optical switch connect by Optical Fiber Composite low-voltage cable (OPLC, Optical Poly Low-voltage Cabel).
Because video camera is connected by the Optical Fiber Composite low-voltage cable with optical switch, and Optical Fiber Composite low-voltage cable light harvesting fibre, transmission of electricity copper cash, copper holding wire are for one, be that optical cable and power line are one, so need not independent power line, wiring is simple, construction volume is little, cost is low.
Description of drawings
Fig. 1 is the transverse sectional view of Optical Fiber Composite low-voltage cable of the present utility model;
Fig. 2 is the structural representation of the supervising device of electric power system of the present utility model.
Embodiment
As shown in Figure 2, the supervising device of this electric power system, the information processing centre that comprises video camera, the network equipment and the rear end of front end, video camera has optical fiber interface, the network equipment is an optical switch, video camera and optical switch connect by Optical Fiber Composite low-voltage cable (OPLC, Optical Poly Low-voltage Cabel).
Preferably, as shown in Figure 1, the Optical Fiber Composite low-voltage cable comprises four-core optical fiber 2 and a pair of power line 1 that transmits data.
Preferably, the two ends of four-core optical fiber connect the optical fiber interface of optical switch and video camera respectively, and a pair of power line connects the power supply unit of video camera.
Preferably, video camera is the high-definition camera of resolution greater than 720P.
Preferably, optical switch is three layers of optical-fiber network switch of rack.
OPLC is the Optical Fiber Composite cable product that State Grid Corporation of China carries out.This product light harvesting fibre, transmission of electricity copper cash, copper holding wire can solve problems such as broadband access, equipment electricity consumption, emergency signal transmission for one; Have characteristics such as high reliability data transmission, price be low, easy to connect, advantage have external diameter little, in light weight, take up room little; Optical cable and power line are avoided the secondary wiring in one, reduce engineering cost; Product has good bending and anti-side pressure performance; Solve the communication issue of power network.OPLC applies to the closed-circuit TV system of power plant, and adopts full HD optical interface video camera, just makes to connect up system monitoring definition height simply, and construction volume is little, and engineering cost reduces a lot than traditional industry television system.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; every foundation technical spirit of the present utility model all still belongs to the protection range of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment did.
