Abstract
The utility model discloses a video monitor system based on PON relates to the video monitoring field. Video monitor system based on PON, including OLT, spectrometer, switch, ONU, camera, digital video recorder and display screen, OLT is connected with spectrometer and switch through optic fibre respectively, ONU passes through optic fibre and is connected with the spectrometer, the camera passes through the network and is connected with ONU, digital video recorder passes through the network and is connected with the switch, the display screen is connected with digital video recorder. Because the utility model discloses ONU and spectrometer all are the passive devices among the video monitor system to the power is not needed additionally to increase, equipment cost can be saved in a large number, turn into the light signal with the signal of telecommunication near the camera to reduce the wiring cost.
Description
Technical field
This utility model is related to field of video monitoring and in particular to video monitoring system based on PON.
Background technology
In cell, transmission of video transmits generally by netting twine mode at present, but the usual transmission range of netting twine equipment is less than
100m, is not suitable for distance wiring.When transmission range is longer, then need to convert electrical signals to optical signal by trunking,
It is transmitted by optical fiber, not only need to increase the equipment such as extra switch, optical transmitter and receiver in addition it is also necessary to provide phase to these equipment
The power supply answered, quantities is big, with high costs.
Utility model content
This utility model is directed to transmission of video in prior art and results in the need for extra power supply unit by network cable transmission and carry
Go out the video monitoring system based on PON, this system can be saved equipment cost in a large number and be reduced wiring cost.
The technical solution of the utility model is as follows：
Based on the video monitoring system of PON, including OLT, beam splitter, switch, ONU, photographic head, DVR and aobvious
Display screen, described OLT is connected with beam splitter and switch by optical fiber respectively, and described ONU is connected with beam splitter by optical fiber, described
Photographic head is connected with ONU by network, and described DVR is connected with switch by network, and described display screen is recorded with hard disk
Camera connects.
Above-mentioned ONU is the ONU with PoE function of supplying power.
The above-mentioned ONU being connected with beam splitter has multiple.
Each ONU above-mentioned can pass through network connection with multiple photographic head.
Above-mentioned photographic head is 1 to 4.
Above-mentioned be connected with switch DVR have multiple.
Each DVR above-mentioned has the display screen being attached thereto.
Above-mentioned display screen is LCD or LED.
The beneficial effects of the utility model：Because in this utility model video monitoring system, ONU and beam splitter are all passive
Equipment, from increasing power supply without extra, can save equipment cost in a large number；Light is converted electrical signals near photographic head
Signal, thus reduce wiring cost.
Brief description
Fig. 1 is the video monitoring system structural representation based on PON for this utility model.
Specific embodiment
In order to better illustrate this utility model, it is further described in conjunction with embodiment and accompanying drawing.
Based on the video monitoring system of PON, including OLT4, beam splitter 3, switch 5, ONU2, photographic head 1, HD recording
Machine 6 and display screen 7, OLT4 is connected with beam splitter 3 and switch 5 by optical fiber respectively, and ONU2 passes through optical fiber with beam splitter 3 even
Connect, photographic head 1 is connected with ONU2 by network, DVR 6 is connected with switch 5 by network, display screen 7 is recorded with hard disk
Camera 6 connects.ONU2 is the ONU with PoE function of supplying power；The ONU2 being connected with beam splitter 3 have multiple, each ONU2 can with multiple
Photographic head 1 passes through network connection, according to requirement of engineering, if this point position is mounted with one to four photographic head to monitor one to four
The ONU2 of mouth in the case of angle, can be extended using band, that is, one piece of ONU2 at most can support the bandwidth of four monitoring cameras.With
Switch 5 connects DVR 6 to be had multiple, and each DVR 6 has the display screen 7 being attached thereto, and display screen 7 is
LCD or LED.
Operation principle of the present utility model：Based on the video monitoring system of PON, the telecommunications that photographic head 1 is first gathered by ONU2
Number is converted into optical signal, carries out long range propagation, then the light a plurality of fiber-optic transfer coming by beam splitter 3 by optical fiber
Signal passes through, in the OLT4 of the incoming Control Room of optical fiber, then to show video display 7 by DVR 6
Come.
