Abstract
The utility model provides a PLC (power line communication) camera, characterized by comprising a camera module, a network module, a power line communication module and a power supply module which are connected sequentially. The power supply module is connected to an external AC (Alternating Current) 220V power supply interface; all the modules are in connection through power lines used as audio and video signal transmission lines of the PLC camera. According to the utility model, the power lines are also used as the audio and video signal transmission lines such that the audio and video signals can be transmitted through the power lines, and no other audio and video signal transmission lines are needed. The distance of audio and video signal transmission can be 300 meters and the outside is only provided with the power supply interface; the PLC camera has the advantages of good lightning protection performance, strong anti-interference capability and high image sharpness and is easy to install.
Description
Technical field
The utility model relates to the safety defense monitoring system technical field, particularly a kind of power line communication video camera through the power line audio/video signal transmission.
Background technology
At present, the similar products technology is 3 kinds:
1, the audio-video signal gathered of camera adopts video line to transmit, though have the long advantage of transmission range, the product shortcoming is that transmission signals is an analog signal, and definition is not high, and construction wiring difficulty is high, and external interface is many, and lightning protection properties is poor;
2, the audio-video signal of camera collection transmits through netting twine, has the high advantage of image definition, but product shortcoming construction wiring difficulty is high, and transmission range is 100 meters, and external interface is many, and lightning protection properties is poor;
3, the audio-video signal of camera collection transmits through wireless, and the product shortcoming is that transmission range is short, and external interface is many, and lightning protection properties is poor, poor anti jamming capability.
In sum, be necessary to provide a kind of transmission range length, clear picture and the easy video camera of constructing.
The utility model content
In order to overcome the defective of enumerating in the background technology, the utility model provides a kind of PLC (Power Line Communication, power line communication) video camera.
The technical scheme of the utility model is: a kind of power line communication video camera; It comprises a video camera module, a mixed-media network modules mixed-media, a power line communication module and a power module that is linked in sequence; Power module is connected to outside alternating current 220V power interface, all connects through the power line as video camera audio-video signal transmission line between said each module.
Compare with existing video camera, the utility model possesses following advantage: because the double audio-video signal transmission line of doing of power line, audio-video signal can be through the power line transmission; Need not to lay in addition the audio-video signal transmission line, the audio-video signal transmission range reaches 300 meters, and the outside has only power interface; Lightning protection properties is good; Antijamming capability is strong, and image definition is high, is easy to install.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
Fig. 1 is the utility model modular structure sketch map.
Embodiment
As shown in the figure; The PLC video camera of present embodiment; It comprises a video camera module, a mixed-media network modules mixed-media, a PLC module and a power module that is linked in sequence, and power module is connected to outside alternating current 220V power interface, all connects through power line between said each module; Simultaneously, the audio, video data transmission line between double each module of making this PLC video camera of said power line.
Video camera module audio frequency acquiring signal and image signal data are transferred to mixed-media network modules mixed-media; Mixed-media network modules mixed-media carries out analog-to-digital conversion and compression with the analog signal that the video camera module collects; Through network interface the digital audio-video signal of handling is sent to the PLC module; The PLC module is modulated load signal to power module with digital video signal, and power module outputs to modulation signal on the alternating current 220V power line, through the alternating current 220V power line audio frequency and video digital data transmission is gone out again.
Claims (1)
1. power line communication video camera; It is characterized in that: comprise the camara module, a mixed-media network modules mixed-media, a power line communication module and the power module that are linked in sequence; Power module is connected to outside alternating current 220V power interface, all connects through the power line as video camera audio-video signal transmission line between said each module.
