Background technology
Power line communication technology (Power Line Communication, be called for short PLC), mainly be meant utilize the power line transmission data and a kind of communication technology.As far back as the '20s initial stage in last century, just become a reality by power line communication.The PLC technology with its need not wiring, wide coverage, easy to connect, channel reliability height, small investment instant effect, with advantages such as power grid construction is synchronous, can be divided into arrowband PLC and broadband P LC in the power line communication field at present, arrowband PLC refers to ZAP, and transmission speed is low; Broadband P LC technology (being called for short the PLC technology) then is meant the communication technology of utilizing the power line high speed transmission data.The PLC modulation technique has following several: frequency shift keying modulation technique (FSK), binary phase shift keying modulation technique (BPSK), utilize M system phase shift keying modulation technique (QPSK), orthogonal amplitude modulation technique (QAM), spread-spectrum modulation technique (CDMA), multi-carrier modulation technology (DMT), Orthodoxy Frequency Division Multiplex modulation technique (OFDM) etc.
Existing video monitoring mode mainly contains following several mode: (1) is the video monitoring system of cable transmission analog signal directly; (2) video monitoring system that connects by DVR; (3) video monitoring system by the interconnected network mode transmission of digital signals; (4) video monitoring system of transmitting by wireless mode.The shortcoming of above-mentioned four kinds of modes is that bandwidth is narrow, speed is slow excessively, real-time is poor, stability is not high, is difficult to be applicable to the monitoring of multi-user to single point, work progress more complicated in addition, operating expenses height.
The utility model content
The utility model provides a kind of power line broadband network video monitoring system, and purpose is to utilize the PLC technology to realize the transmission of data, saves the broadband resource of remote transmission.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of power line broadband network video monitoring system is characterized in that: comprise video acquisition end, collection terminal electric network bridge, power line, monitoring client electric network bridge and monitoring client; Video acquisition end output is connected with the collection terminal electric network bridge, and collection terminal electric network bridge and monitoring client electric network bridge are connected on the power line, and the monitoring client receiving terminal is connected with the monitoring client electric network bridge.
Requisite power line network when the utility model has utilized equipment operation, directly carry out the transmission of teledata by power line, connection had easily both reduced the cost of construction and had reduced the difficulty of construction, can make transfer of data arrive the area that power line can reach again.It is more stable, more clear to the utlity model has image transmission, has solved simultaneously that the broadband is narrow in the existing video monitoring mode, speed is slow excessively, real-time is poor, the not high shortcoming of stability.
