Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises second line of a couplet mouth, port, data electric power separation module, data transmission control module, rectification back flow protection circuit, 12V flow-limiting voltage-stabilizing module, 9V flow-limiting voltage-stabilizing module, first voltage output V1 and the second voltage output V2, described second line of a couplet mouth is connected with the communication of described data electric power separation module, being connected with described data transmission control module data communication of described data electric power separation module, the current output terminal of described data electric power separation module is connected with the current input terminal of described rectification back flow protection circuit, the current output terminal of described rectification back flow protection circuit is connected with the current input terminal of described data transmission control module and described 12V flow-limiting voltage-stabilizing module respectively, the current output terminal of described 12V flow-limiting voltage-stabilizing module is connected with the current input terminal of described 9V flow-limiting voltage-stabilizing module and the first voltage output V1 respectively, the current output terminal of described 9V flow-limiting voltage-stabilizing module is connected with the current input terminal of described second voltage output V2, described port is connected with described data transmission control module communication, described first voltage output V1 is 12V voltage output, described second voltage output V2 is 9V voltage output.
Data electric power separation module: user side is connected to the second line of a couplet mouth RJ45 port of mixer during by modulator-demodulator, RJ45 port carries data and electric power signal simultaneously.Data electric power separation module therefrom extracts data with electric power signal and is separated;
Data transmission control module: this module uses the control of High-Speed Double-Channel analog switch realization to data transmission channel break-make, only detects that the electric power signal separated just opens data transmission channel.If user does not use modulator-demodulator, second line of a couplet mouth RJ45 port will not carry electric power signal, and data transmission module, owing to electric power signal not detected, does not therefore open data transmission channel, and namely now this user could not get on to the Net.Realize thus only could normally surfing the Net with the use of during modulator-demodulator.
Rectification back flow protection circuit: use rectifier diode that the AC power signal separated is rectified into DC power signals.This rectifier diode plays the effect of back flow protection equally simultaneously.If namely mixer inside occurs that the electric power signal of overvoltage or overcurrent is back to user side, the damage of ustomer premises access equipment may be caused.And this module can stop over-voltage and over-current signal to pass through, and then avoid the generation of this problem.
12V flow-limiting voltage-stabilizing module: use power supply voltage stabilizing chip that the electric power signal separated is carried out flow-limiting voltage-stabilizing to 12V, be supplied to the 12V network equipments such as light cat and router and power.
