Embodiment
Technical scheme for a better understanding of the present invention, describe embodiment provided by the invention in detail below in conjunction with accompanying drawing.
The embodiment of the present invention provides a kind of power line indoor audio call system, as shown in Figure 1, comprise: a PLC gateway and at least one audio call terminal, described audio call terminal is connected with described PLC gateway by power line, between described audio call terminal, by power line, interconnect, as shown in Figure 2, described audio call terminal has a HomePlug-AV communication chip group, first processor (CPU), audio frequency is processed and amplifying circuit, audio input circuit, audio output circuit and the first coupling circuit, described audio input circuit is connected respectively described audio frequency with described audio output circuit to be processed and amplifying circuit, described audio frequency is processed and amplifying circuit connects described first processor, described first processor connects a described HomePlug-AV communication chip group, a described HomePlug-AV communication chip group connects described the first coupling circuit, described the first coupling circuit connects described PLC gateway by power line, and described the first coupling circuit also connects the first coupling circuit of another audio call terminal by described power line.The indoor audio call system of this power line utilizes power line as signal transmission medium, has adopted the HomePlug-AV technology to realize IP-based calling communication architecture.The audio call terminal is connected with the PLC gateway by power line, and is independently IP address of audio call terminal distribution by router.Each audio call terminal, can be set to the different call models of point-to-point or point-to-multipoint, realizes calling and control between each audio call terminal.Router is connected with the intelligent mobile terminal communication by wireless signal.
When call button or infrared remote control receiver receive the triggering signal of Infrared remote controller, by audio input circuit (microphone) accessing to audio input signal, and process and amplifying circuit will be called out control command and audio signal and be loaded into a HomePlug-AV communication chip group and encoded through first processor and audio frequency, transfer to power line through the first coupling circuit (as: power line coupler) again, realize the calling of another the called audio call terminal to setting in advance.Simultaneously, when called audio call terminal receives the calling control command from power line, model call link, and receive signal by the first coupling circuit, decoded through a HomePlug-AV communication chip group again, finally processed by first processor and audio frequency and amplifier is realized the control to audio output circuit (loud speaker).
In the above-described embodiments, more specifically, described PLC gateway comprises the 2nd HomePlug-AV communication chip group and the second processor, and described the second processor connects described the 2nd HomePlug-AV communication chip group, and described the 2nd HomePlug-AV communication chip group connects the second coupling circuit.
As shown in Figure 3, the indoor audio call system of described power line, also can utilize described audio call terminal to realize the control function of gate access inter-speaking.Any audio call terminal is fixing as doorway audio call terminal, and preset called indoor appointment audio frequency calling terminal, when gate inhibition's button of described doorway audio call terminal triggers, by power line, control its preset called audio call starting terminal, thereby realize the gate access inter-speaking function.
As shown in Figure 4, the indoor audio call system of described power line, also can utilize described audio call terminal to realize the playing function of background music.Any audio call terminal is fixing as the source of sound terminal, the source of sound input circuit access sound source signal (as MP3) of described source of sound terminal also continues the source of sound of playing, and using other audio call terminal as playback terminal, the output that can pass through control button selective reception or mute speaker of described playback terminal, or volume or source of sound are implemented to control, thereby realized the broadcasting of power line background music and controlled function.
