To reach above-mentioned purpose, what technical scheme was specifically realized in:
One aspect of the present invention provides a kind of in-car communication system based on Power Carrier technology, including:Power line, For providing electric energy, Bing Weige roads voice signal carries out carrier wave;Control main frame, connects power line, for for the distributed language in each road Sound circuit is powered, and Bing Weige roads voice signal carries out audio mixing;At least one distributed sound circuit, each distributed sound circuit Control main frame is connected respectively, and for handling voice signal, it is defeated that the electric signal that the microphone diaphragms of electrophone are produced is changed Enter audio electrical signal to be added on the voltage of power line offer, and output audio electrical signal is exported to the earphone of electrophone; At least one electrophone, each electrophone connects a distributed sound circuit respectively, for that will export audio electrical signal Be converted to acoustic energy to export by earphone, and the electric signal that microphone diaphragms are produced is converted into input audio electrical signal.
In addition, electrophone uses tensile type antioise headset.
In addition, control main frame and/or distributed sound circuit use pure design on board level.
In addition, distributed sound circuit uses audio inductance.
As seen from the above technical solution provided by the invention, the car based on the Power Carrier technology present invention provided In interior communication system batch application and the special entrucking of Multiple Type, reliable operation.
The system can also apply subsequently develop it is short, in, in long-range weapon and civil equipment.
Meanwhile, by using Power Carrier technology, the versatility of in-car communication system design is improved, product is shortened and opens In the hair cycle, reduce research and development of products expense.
Voice circuit module of electricization is designed, and position needed for special entrucking can also be installed on nearby, reduces audio signal wire path loss Consumption.
Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, below will be to that will use needed for embodiment description Accompanying drawing be briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for this For the those of ordinary skill in field, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings Accompanying drawing.
Fig. 1 is the structural representation of the in-car communication system provided in an embodiment of the present invention based on Power Carrier technology.
Embodiment
Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
Fig. 1 shows the structural representation of the in-car communication system provided in an embodiment of the present invention based on Power Carrier technology Figure, referring to Fig. 1, the in-car communication system provided in an embodiment of the present invention based on Power Carrier technology, including:
Power line, for providing electric energy, Bing Weige roads voice signal carries out carrier wave;
Control main frame, connects power line, for being powered for each road distributed sound circuit, and Bing Weige roads voice signal is carried out Audio mixing;
At least one distributed sound circuit, each distributed sound circuit connects control main frame respectively, for handling language Message number, the input audio electrical signal of the electric signal conversion that the microphone diaphragms of electrophone the are produced power line that is added to is provided Voltage on, and by output audio electrical signal export to the earphone of electrophone;
At least one electrophone, each electrophone connects a distributed sound circuit respectively, for that will export sound Frequency electric signal is converted to acoustic energy and exported by earphone, and the electric signal that microphone diaphragms are produced is converted into input voiceband telecommunication Number.
Specifically, the design philosophy of circuit system is Power Carrier technology, power line Ji Weige roads sound circuit power and Carrier wave is carried out for each road voice signal.
The devices such as DC/DC modules and inductance can be installed in control main frame, power supply is provided for each distributed circuit, while to divide The carrier of cloth circuit voice signal, audio mixing is carried out to voice signal.
The effect of distributed sound circuit is processing voice signal, and the electric signal that microphone diaphragms are produced is through speech chip Processing is converted to audio electrical signal and is added on supply voltage, and speech chip exports audio electrical signal to earphone, is turned by earphone It is changed to acoustic energy.Realize a people to speak, remaining many speech communication that can be heard per capita.
Wherein, in-car communication system performance indications:
System working power:12VDC;
Per road power consumption:600mW;
Microphone input gain:52dB;
