Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of a kind of electric power modem in the utility model embodiment.
Embodiment
The utility model embodiment provides a kind of electric power modem, see Fig. 1, is below described in detail.
Electric power modem comprises: zero cross signal split circuit 101, exchanges and turns DC circuit 102, power line signal coupling circuit 103, one-touch mains switch 104, filter circuit 105, power line communication processing module 106, Ethernet network interface 107.
The two-way electric-power wire communication signal be coupling in outer low pressure alternating current is separated by filter circuit 105, and isolated two-way power communication signal is sent to power line communication processing module 106, zero cross signal split circuit 101 is for the low-voltage AC TR-from outside, zero passage detection signal is isolated in TR+, and zero passage detection signal is transported to power line communication processing module 106, power line communication processing module 106 is connected with Ethernet network interface 107, power line communication processing module 106 is according to the two-way electric-power wire communication signal received and zero passage detection signal, generate ethernet signal, ethernet signal is sent to Ethernet interface 107.
In the present embodiment, will stress one-touch mains switch 104, the function of all the other parts of electric power modem and the particular circuit configurations of these all the other parts can see existing electric power modems.
One-touch mains switch 104, comprise a button (SW) 1041, a PNP triode 1042, a NPN triode 1043 and a resistance (R1) 1044, a resistance (R2) 1045, the emitter of PNP triode 1042 with exchange the VDD output turning DC circuit 102 and be connected, the collector electrode of PNP triode 1042 is connected with the VCC input of power line communication processing module 106, PNP triode 1042 base stage be connected with one end of resistance (R2) 1045, the other end of resistance (R2) 1045 is connected with the collector electrode of one end of button 1041 and NPN triode 1043, the emitter of NPN triode 1043 is connected with one end of resistance (R1) 1044, the base stage of NPN triode 1043 is connected with the GPIO input of power line communication processing module 106, the other end ground connection of resistance (R1) 1044, the other end of resistance (R1) 1044 is also connected with the other end of button (SW) 1041 simultaneously.
When electric power modem is not started shooting, button 1041 disconnects, the VCC mouth of PNP triode 1042 and the GPIO mouth of NPN triode 1043 are low level, and PNP triode 1042 and NPN triode 1043 are all in cut-off state, and power line communication processing module 106 is energising not.
When electric power modem needs start, button 1041 is pressed, the ground level of PNP triode 1042 is connected with GND and presents low level, cause PNP triode 1042 conducting, now NPN triode 1043 still ends, power line communication processing module 106 powers on the initialize routine that brings into operation, and the GPIO mouth NPN triode 1043 in initialize routine is set to high level, NPN triode 1043 conducting.Then, button 1041 unclamps, and due to NPN triode 1043 conducting, PNP triode 1042 is also in conducting state, and power line communication processing module 106 has also been in electricity condition, and the successive procedure after initialize routine normally runs.
When electric power modem needs shutdown, button 1041 is pressed, power line communication processing module 106 normally works, power line communication processing module 106 runs shutdown programm, shutdown programm detects the step that button 1041 is pressed, shutdown programm is set to low level the GPIO mouth of NPN triode 1043, then NPN triode 1043 ends, then, button 1041 unclamps, PNP triode 1042 is also ended, and cause the VCC mouth of PNP triode 1042 to be low level, power line communication processing module 106 enters power-off shutdown state.
Optionally, power line communication processing module 106 can adopt push pull mode to arrange GPIO mouth by initialize routine and shutdown programm.
Optionally, because triode exists leakage current, in order to reduce quiescent dissipation further, can PNP triode 1042 and NPN triode 1043 be changed into CMOS tube.
It should be noted that, VCC is the DC power supply of power line communication module, have more than the DC power supply representing a fixed voltage value, the power supply of multiple direct voltage may be comprised, but multiple magnitudes of voltage that may comprise are all changed by VCC and obtain, the switch of whole power modem device therefore just can be controlled by the switch of control VCC.
Electric power modem in the utility model embodiment comprises one-touch mains switch, thus when not needing to use Homeplug, light one presses, and can cut off the power-supply system of Homeplug without the need to plugging Homeplug, control the switching on and shutting down of Homeplug, reach the object of energy-conserving and environment-protective.
