The audio data remote transmission system based on wireless communication according to claim 4, characterized in that: The process in which the audio decoding module receives the encoded data stream transmitted through the wireless transmission path and performs decoding operation to obtain the corresponding original audio signal includes: The audio decoding module receives the coded data streams transmitted from the corresponding wireless transmission paths, and obtains the coding source information associated with each coded data stream, the coding source information including the coding timestamp, coding frequency, coding bit number and coding node position; The corresponding decoding order is set according to the size of the encoding timestamp corresponding to the encoded data stream, and the decoding order is: the larger the encoding timestamp corresponding to the encoded data stream, the earlier its decoding order is; the decoding frequency of the corresponding decoding operation is set according to the encoding frequency corresponding to the encoded data stream; the decoding bit number of the corresponding decoding operation is set according to the encoding bit number; and the decoding node position of the corresponding decoding operation is set according to the encoding node position; When the decoding frequency, decoding bit number and decoding node position corresponding to each coded data stream are set, a decoding operation is performed on each coded data stream to obtain the original audio signal corresponding to each coded data stream.

6. The audio data remote transmission system based on wireless communication according to claim 5, characterized in that: The process by which the audio output module outputs all original audio signals on the remote target device includes: Set the display period corresponding to the audio output module and record it as T 展示 , there is T 展示 =[t 始 , t 终 ], t 始 is the start time of the display period, t 终 is the end time corresponding to the display period; The remote target device is provided with a corresponding data display area, and the area corresponding to the data display area is obtained and recorded as S 区域 , set the carousel component, which is used to cyclically output and display different audio signals, obtain the display area area of ​​the component display area corresponding to the carousel component, and record the display area area as S 展示 ; Then according to S 区域 and S 展示 Set the number of carousel components in the data display area of ​​the remote target device, and denote the number as λ, then λ=S 区域 / S 展示 , λ>0 and λ is an integer, when S 区域 / S 展示 When the calculated value is a decimal, the entire value is rounded up; In t 始 At the corresponding start time, the output display of λ carousel components is performed simultaneously in the data display area corresponding to the remote target device. Each carousel component records an original audio signal. 终 At the corresponding termination time, the remote target device is set to a standby inspection state, and all the carousel components are closed in the current data display area.
