Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.
By reference to the accompanying drawings 1, a kind of power-supply system communicated by ac power supply line, comprise power output end and be connected to the load power source of power output end, also comprise bidirectional switch S1, S2, Control on Communication power supply, communication controler, host computer, the two ends of described bidirectional switch S1 are serially connected in power output end, the control end of bidirectional switch S1 connects communication controler, the two ends of bidirectional switch S2 connect power output end and Control on Communication power supply respectively, the control end of bidirectional switch S2 connects communication controler, described communication controler communication connection Control on Communication power supply, described load power source comprises power-supply controller of electric, power-supply controller of electric connects Control on Communication power output end and load power source input respectively, described communication controler and host computer communicate to connect.

Described load power source, communication controler, Control on Communication power supply spatially can arrange a place, and also can keep at a certain distance away, spacing distance is no more than 10KM.
Described load power source is at least one.
When load power source normally work namely have output voltage and bringing onto load work time, its input voltage effective value starts threshold value V1 higher than certain, and PC control communication controler controls bidirectional switch S1 and closes, and bidirectional switch S2 opens, when needing to control load power source, PC control communication controler controls bidirectional switch S2 and closes, S1 opens, host computer transmission control command is to communication controler, communication controler is converted to Control on Communication power supply voltage signal after receiving control command and transmits, the effective value of Control on Communication power supply voltage signal or peak value are lower than V1, therefore load power source does not export or can not bringing onto load work, and its inside or external power-supply controller of electric can work at this voltage, voltage detecting circuit on power-supply controller of electric is transferred to communication processing circuit after corresponding voltage signal being detected, communication processing circuit by process after Signal transmissions to single-chip microcomputer, single-chip microcomputer stores the instruction received after voltage signal is converted to load power source internal control signal.After sign off, closed by S1, S2 opens, and load power source normally works, and according to receive and the instruction stored carries out regulating and control to its output.
The utility model by the starting resistor effective value of setting load power source higher than V1 by Control on Communication electric power output voltage effective value or peak-settings lower than V1, realize the function at the enterprising Serial Communication of supply line.As shown in Figure 1.Wherein most typical application scenarios is as follows: outdoor remote LED is as street lamp, and generally can turn off the light by day, turn on light in the evening, in the dead of night, carry out light modulation, reduces the brightness of lamp, realizes secondary energy-saving with this.Current LED power generally adopts 0-10V simulation dimming mode to coordinate with peripheral control unit, when needing light modulation, only need change the output voltage (within 0-10V) of Control on Communication power supply.When needs light modulation time, due to aspects such as traffic safety, can not occur lamp flicker or time bright time the phenomenon such as to go out.In this case, install one additional to be powered by AC line and the device communicated (lamp power source controller) can realize above-mentioned functions in the inside of each lamp.When adopting controllable silicon dimmer, because same line power is very large, the cost of dimmer is very high.And during the scheme adopting the utility model to recommend, can by day or at dusk, before turning on light, the time interval needed for light modulation, amplitude, other control informations etc. sent to load power source by communication control unit through supply line in advance in advance and store, owing to adopting low voltage when communication, LED power can't work lamp in other words can't be bright, the impact of visual aspects can not be caused, and lamp power source controller can with extremely low power dissipation work under communication voltage (lower than V1) condition, therefore Control on Communication power supply cost is lower, is easy to realize.The cost of lamp power source controller also very low lamp power source controller and LED power is arranged together, and the output of lamp power source controller connects the light modulation line of LED power, lamp power source controller and the input common power supply circuit both LED power.
