Formula is audio signal and the data wire directly simultaneous transmission on single line, and the drawbacks of this mode is present is：When monobus transmission
During data, audio all typically is transmitted using the frequency of high code rate, causes the anti-interference of its data transfer signal poor, and
And disturbed for the HFS of tonequality also than larger；Another way is that audio signal and data time-sharing multiplex are transmitted, so
Above one section is data, and middle one section is audio, behind one section be data, this effect to tonequality has greatly improved, but
Be delay and interference be also that can not be ignored.In a system of the invention, it is desirable to have the tonequality of high-fidelity, additional long-distance transmissions,
The preliminary distance for reaching more than 100 meters, so the transmission means of existing audio signal/data monobus has larger limitation
Property, therefore, devising data and audio signal classification transmission, when needing data transfer, main frame and slave carry out transmission of shaking hands
Data, otherwise transmit audio signal always above bus, and design main frame and the unidirectionally controlled principle of slave data transfer, by interior
The control of portion's miscellaneous part transmits RS-232 asynchronous data agreements to obtain above monobus, the agreement code check is relatively low, can have
There is preferable noiseproof feature, it can be ensured that more than 100 meters during asynchronous monobus transmission data, data accurate can be passed
It is defeated, and when data transfer is finished, audio signal can be transmitted in this bus again, do not influence the audio signal quality of transmission to ask
