Description
Technical field
The present invention relates to power carrier broadband connections technical field in the low-pressure chamber, relate in particular to a kind of power carrier modem based on the TR-069 agreement.
Background technology
Current, the telecommunication service that the home network carrying is numerous, in order to guarantee telecommunication service service quality end to end, telecom operators need carry out coordinating and unifying management to the numerous equipment that relate in the end-to-end communication, and this wherein just need accomplish may command and can manage home network device.And on the mode of concrete management, can adopt SNMP, TR069 etc.Wherein TR-069 is one of technical specification by DSL FORUM exploitation, and its full name is " a CPE wide area network management agreement ".It has stipulated that home gateway carries out the telemanagement general framework and the agreement in when configuration, is used for from network side home gateway being carried out the remote centralized managing special and is based on pre-configuredly automatically, has removed service supplier's CPE configuration burden fully.
PLC(Power Line Communication, power line communication technology), be meant a kind of communication mode that utilizes power line transmission data and voice signal.This technology is that the high frequency of carrying information is loaded on electric current, and with the electric wire transmission, the modulator-demodulator of receiving information is separated high frequency again from electric current, and is sent on computer or other communication terminals, transmits with realization information then.
PLC utilizes 1.6M to 30M frequency band range transmission signals.When sending, utilize GMSK or OFDM modulation technique that user data is modulated, on power line, transmit then; At receiving terminal, through filter modulation signal is leached earlier, pass through demodulation again, just can obtain former signal of communication.Individual equipment both can modulation signal, again can restituted signal, there is not the branch of local side and client, plug and play.The signal of Access Network is when user side transmits, and the PLC modulator-demodulator of front end is responsible for modulating the signal on user's the distribution line and is transmitted.User side PLC equipment comes out the signal demodulation, passes to equipment such as user's computer again.Otherwise when the user sent data, the power carrier equipment of user side modulated the signal to earlier on the power line, and headend gets off to send to exterior I nternet from the demodulation of power line signal again.
In today of cybertimes, Internet of Things more and more is subjected to people's attention.Some digital terminal equipments of effective monitoring how fast provide reliability height, safe network control, become the difficult point of current Internet of Things development.
Summary of the invention
