Abstract
A security and protection monitoring transmission system with one common cable combining network data signal and power supply comprises multiple internet protocol cameras, multiple supply network switches, a network hard disk video recorder, a mixer and a power supply. The multiple internet protocol cameras and supply network switches are arranged outside a control center, and the network hard disk video recorder, the mixer and the power supply are arranged in the control center. Each internet protocol camera is provided with an internet protocol communication interface and a power supply interface. The internet protocol cameras are connected with the corresponding supply network switches respectively. The mixer is used for mixing the power supply and network signal source into one network cable, so high voltage transmission of the cable combining the network data signal and the power supply is achieved. The mixer comprises multiple input terminals and output terminals. An output terminal of each supply network switch is connected with an input terminal of another supply network switch. By using supply network switches and outputting 12 V direct current to internet protocol cameras, the system resolves a problem that an internet protocol camera needs a separate power supply wire to supply electricity for the internet protocol camera, reduces the number of the network wires in addition, so that the construction difficulty is reduced, and the wire rod cost is saved.
Description
Technical field
The utility model relates to network monitoring device technical field, is specifically related to a kind of netting twine network data signals and power common cable safety monitoring transmission system.
Background technology
At present, information machine room is provided with supervisory control system outward conventionally, so that production safety is monitored.Existing information machine room outer network video monitoring system typically uses multi-core fiber or netting twine enters information machine room realization, for multi-core fiber or netting twine, enter information machine room mode, the image of its each video camera needs to have server in a core fibre or netting twine and information machine room to join.
As shown in Figure 1, prior art network cable transmission distance in network cable transmission is limited, generally can not surpass 100 meters, and POE exchanger power can not surpass 100 meters too, and existing most 1,000,000 high definition networks all do not have POE function.Because each 1,000,000 high-definition network camera will draw a netting twine also will draw a power line to switch, cause the tired multiple-project difficulty in construction midline road high, surpass 100 meters will add switch or by Optical Fiber Transmission, simultaneously also will be at power line of local cloth of each 1,000,000 high-definition network camera.In Optical Fiber Transmission, due to supervisory control system, install and all relatively to disperse, with switch, disperses away after also can only arriving a point while causing Optical Fiber Transmission, also just existing equally wiring be tired of many, the problem that difficulty of construction is large.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of netting twine network data signals and power common cable safety monitoring transmission system, and this system has solved problems of the prior art, is adapted to the work under various complex environments.
In order to solve the problems of the technologies described above, the utility model is realized in the following manner:
A kind of netting twine network data signals and power common cable safety monitoring transmission system, comprise many web cameras and the supply network switch that are arranged at outside control centre, with the network hard disk video recorder, blender and the power supply that are arranged in control centre, wherein web camera is provided with interface and the power interface that procotol is carried out communication, and described web camera is corresponding connected one by one with supply network switch; Described blender is for being mixed into a netting twine by power supply and network signal source, realize cable network data signals and the transmission of power supply high voltage altogether, blender comprises a plurality of inputs and output, input is connected with power supply with network hard disk video recorder respectively, by output, be connected with the input port of a supply network switch, the output port of described supply network switch is connected with the input port of another one supply network switch.
Preferably, described supply network switch input voltage range is direct current 30-110V, and the direct current of output 12V, for the power supply of web camera.
Described supply network switch adopts oppositely the power transmission means of multi-stage cascade of netting twine.
Compared with prior art, the beneficial effect the utlity model has: the utility model adopts supply network switch, by it, export 12V direct current to video camera, solved to the independent cloth power line trouble of 1,000,000 high definition network and reduced netting twine quantity, reduce difficulty of construction, cost-saving, solved existing common 1,000,000 high-definition network cameras does not have yet operable problem of POE function simultaneously yet.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, embodiment of the present utility model is described in further detail.
As shown in Figure 2, a kind of netting twine network data signals and power common cable safety monitoring transmission system, comprise many web cameras and the supply network switch that are arranged at outside control centre, with the network hard disk video recorder, blender and the power supply that are arranged in control centre, wherein web camera is provided with interface and the power interface that procotol is carried out communication, and described web camera is corresponding connected one by one with supply network switch; Described blender is for being mixed into a netting twine by power supply and network signal source, realize cable network data signals and the transmission of power supply high voltage altogether, the direct voltage that the voltage output range of transmission is 30-110V, adopt oppositely the power transmission means of multi-stage cascade of netting twine, blender comprises a plurality of inputs and output, input is connected with power supply with network hard disk video recorder respectively, by output, be connected with the input port of a supply network switch, the output port of described supply network switch is connected with the input port of another one supply network switch.
By blender, direct current 30-110V power supply and network signal are mixed on a netting twine.The netting twine that transmits out from blender, existing power supply also has network signal, by having adopted co-cable transmission mode, use 8 or 4 cores in netting twine to transmit power supply simultaneously, can effectively reduce power supply loss on the line, and netting twine is out connected on first supply network switch from blender, through this supply network switch conversion, isolate network signal and direct current 12V power supply is supplied with web camera; Another port of this supply network switch is drawn a netting twine that includes network signal and power supply simultaneously, again be connected on next supply network switch and use, with this, circulate and realize multi-stage cascade, thereby reach network data and power delivery to larger distance.
The above is only execution mode of the present utility model; statement again; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also carry out some improvement to the utility model, these improvement are also listed in the protection range of the utility model claim.
