At present, being connected to network generally is to connect by wired or wireless device, because it is bigger that wireless device is subjected to the influence of signal strength signal intensity, generally under signal shielding zone or weather conditions such as overcast and rainy, signal strength signal intensity is affected, so wireless device can only be used for some customers not high to the stability requirement of signal, main flow equipment commonly used at present still is wired.And wiring logging-on function equipment generally depends on netting twine and transmits, and this depends on different webserver providers again, in case use wireline equipment to surf the Net, need pre-install wireline equipment in earlier stage and set up netting twine, and this itself just brings certain cost.
The utility model content
The purpose of this utility model provides a kind of transmission control equipment that netting twine just can be surfed the Net that do not need to set up, as long as have power line to pass through in the family, can use.
The purpose of this utility model is to be achieved through the following technical solutions:
The power line network transmission control unit (TCU), comprise master control module, OFDM modulation and demodulation module, the network No. reception of OFDM ether and transport module, PLC channel management module and power supply and carrier module, the main control chip model of its master control module is DSS9001, the main control chip model of OFDM modulation and demodulation module is DSS7700, and OFDM ether network No. receives and the main control chip of transport module is RTL8201CP; Wherein
The master control module, it mainly is made up of DSS9001 chip and peripheral circuit thereof, and realization is to Signal Processing and convert ethernet signal to;
OFDM modulation and demodulation module, it mainly is made up of DSS7700 chip and peripheral circuit thereof, realizes modulation and demodulation to OFDM;
OFDM ether network No. receives and transport module, and it mainly is made up of RTL8201CP chip and peripheral circuit thereof, realizes ethernet signal is received and transmission;
PLC channel management module, it mainly selects to transmit with signal to the PLC passage;
Power supply and carrier module, it is mainly other each functional module power supply and carries out reception and the transmission (power line coupling) of OFDM.
The SPI of master control module, AFE_DAC, FE_ADC interface dock with SPI, AFE_DAC, the AFE_ADC interface of OFDM modulation and demodulation module respectively, OFDM ether network No. receives and the MII interface of transport module docks with the MII interface of master control module, and OFDM ether network No. receives and the nRES interface of transport module is modulated with master control module and OFDM and demodulation module nRES dock, OFDM modulation and demodulation module the PLC interface dock with PLC channel management module PLC interface, PLC channel management module is connected with power supply and carrier module.
By above-mentioned design, realized power line transmitting data signal, as long as have the electricity local user just can: surf the Net, see interactive TV.This product rate stabilization, safe and reliable, fitting operation is simple and easy, is the network equipment of desirable family online, Audio on Demand, video conference, game on line, video request program.
