Abstract
The utility model discloses a kind of DC power line current carrier communication system, comprise the client load and Switching Power Supply that connect through DC power line, described client load communication link is connected to signal transmitting module, and this signal transmitting module comprises modulator and the first magnetic device; Described Switching Power Supply communication link is connected to signal receiving module, and this signal receiving module comprises demodulator and the second magnetic device.The utility model solves the data communication problem that Switching Power Supply and client do not increase wire, and radio communication cost is lower relatively, is worthy to be popularized.
Description
Technical field
The utility model relates to a kind of DC power line current carrier communication system.
Background technology
At present, most of Switching Power Supply requires there is data communication function with client, and structure and the mode of most communication system are as described below:
(1) wire communication---duplex communication (as Fig. 1), is provided with two wires between client load and Switching Power Supply, but the restriction of client condition, can not wire be increased between Switching Power Supply and client;
(2) radio communication device (as Fig. 2), client load is connected with wireless base station apparatus through holding wire, and Switching Power Supply is connected with radio receiver through holding wire, and wireless base station apparatus and radio receiver communicate to connect, although this structure can meet the demands, cost is high.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model completes the DC power line current carrier communication system with the data communication of client under providing a kind of condition not increasing wire and do not use wireless communication technology between power supply and client.
It is as described below that the utility model solves the technical scheme that its technical problem adopts: a kind of DC power line current carrier communication system, comprise the client load and Switching Power Supply that connect through DC power line, it is characterized in that, described client load communication link is connected to signal transmitting module, and this signal transmitting module comprises modulator and the first magnetic device, described Switching Power Supply communication link is connected to signal receiving module, this signal receiving module comprises demodulator and the second magnetic device, the data that client load will communicate are sent to signal transmitting module, different pieces of information is converted to the square wave of different frequency and different number by the modulator of signal transmitting module inside, as signal wave, the ac high frequency pulse current of signal wave and modulator inside produces AC modulated current, again AC modulated current is coupled on DC power line by the first magnetic device, DC power line superposes with the DC quantity of constant value and produces carrier current signal, carrier current signal on DC power line is coupled on signal receiving module by the second magnetic device, signal receiving module is separated and detects modulating wave, corresponding signal ripple is demodulated again by the demodulator of inside, transmission data are solved according to square wave frequency and number, send Switching Power Supply to for detection and control.
According to the utility model of said structure, its beneficial effect is, the utility model solves the data communication problem that Switching Power Supply and client do not increase wire, and radio communication cost is lower relatively, is worthy to be popularized.
