For example, when an audio source output is connected to the °8, the audio output can be played through the racquets publicly, but when the other source is connected to the headphones, Only by plugging in the headphone output, the audio output is connected, and the audio output connected to the bar is immediately discontinued. The above design is mainly based on the fact that the publicly played audio may cause interference to other people. Audio, however, once the headset is used, 'only a single user wearing the headset can hear the audio and can't share it with anyone other than the user. Even if others wear headphones, they can't share it. For the above situation, 'If the earphone used is wired, or you can use the tap to split the audio output into two, or divide it into 纟, for more wired headphones to plug in to share audio, but wireless headphones The situation can only be - for a transmission 'This is because the wireless headset uses digital wireless transmission, the general number 4 201249117 wireless transmission headset, there will be a dedicated 丨D between the transmitter and the receiver to transmit data in the wireless time zone Between other unrelated transmission and reception signal data' to avoid mis-transmission or interception of signal data, and when receiving data stream at the receiving end, it can also send back an acknowledgment (ACK) signal to the transmitting end by using the ID used to avoid the data string. The flow is not interrupted by the receiving end due to external environment interference, but this return confirmation design also enables the digital wireless transmission headphones to be used only one-to-one, mainly due to two (or more) When the receiving end receives the signal of the transmitting end at the same time, each receiving end will return the confirmation signal and interfere with each other after receiving the signal, so that the transmitting end cannot receive the returning confirmation message. Repeated transmission; if only one of the receiving ends does not return the acknowledgment signal because it has not received the signal, but because the transmitting end has received the acknowledgment signal from another receiving end and does not repeat the transmission, it will make The receiving end that has not received the signal can not receive the re-transmitted signal and there is a sound-breaking phenomenon; based on the above situation, a digital wireless transmitter can only be used with one wireless earphone; and the above wireless transmission technology has the advantage of anti-eavesdropping The security function is different from the earphones that usually use FM (FM) or AM (Radio Frequency Modulation) radio. Although there is no limit to the number of receiving headphones, there is no anti-eavesdropping security function; but the disadvantage is that it cannot be shared. SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to provide a one-to-many wireless data transmission method that solves the mutual interference phenomenon that may occur when an existing wireless data transmission returns a confirmation signal, so that more than two receiving ends can be used. Normally receive the data transmitted by the same transmitter for easy sharing. The technical means adopted for achieving the foregoing purpose is that the one-to-many wireless 201249117 data transmission method has a transmitting data transmission program, and the transmitting data transmission program is executed after a connection is established between one transmitting end and one or more receiving devices. The following steps: loading new data; adding serial numbers to the loaded data; transmitting the data of the added serial number; receiving the return confirmation signal, and judging whether the receiving device of the connection returns all the confirmation signals; if all the returns are repeated, the method is repeated The preceding step; if any receiving device does not return the confirmation signal, the data is repeatedly transmitted. Another technical means for achieving the foregoing objective is that the one-to-many wireless data transmission method has a receiving end transmission path, and the receiving end data transmission program is after the connection between the receiving device and the transmitting end. Perform the following steps: Receive the data; Compare the serial number of the data; : Determine whether the serial number of the data is repeated. If the serial number of the data is not repeated, output the data of the i-pen, then return the confirmation signal, and then return to the step of receiving the data; If the serial number of the right data is repeated, the data is discarded, and then the echo signal is returned, and then the step of receiving the data is returned. As can be seen from the above, the present invention is for each transmitting device to send a serial number, each receiving device When receiving each piece of data, it will first determine whether the poor material serial number is repeated. 'If it is not repeated, it will output (play) the data and return the confirmation signal. If the data serial number is repeated, it means that there are two data to receive the transmitting end at the same time. And more than one receiving device does not return the confirmation signal to the transmitting end because the data is not received by 201249117, and the transmitting end repeatedly transmits the data of the same serial number in the condition that it is determined that the receiving device has not returned the confirmation signal. The receiving device that has received the data will repeatedly receive the same data with the same serial number. Therefore, the data will be discarded and the confirmation signal will be returned. By using the above method, all receiving devices can be ensured when transmitting data to two or more receiving devices simultaneously at the transmitting end. Can receive the data, when any receiving device does not receive the data 'transmitting will send data repeatedly' to ensure that all receiving devices do not The data is interrupted, and the serial number comparison enables the receiving device that repeatedly receives the same serial data to automatically discard the data to ensure that the receiving device can operate normally. Therefore, more than two receiving devices can simultaneously share one transmission by using the above method. The data sent by the terminal. [Embodiment] A preferred embodiment of the present invention, as shown in the figure, is mainly provided with a digital wireless transmitter 2 在一 on a host 1 〇 as a transmitting end, the digital wireless transmitter 20 Simultaneously connecting with two or more receiving devices 30, and receiving, by the receiving devices 3, the data sent by the digital wireless transmitter 20; the host computer 1 includes but is not limited to: a personal computer called a notebook computer (10), The tablet computer and the mobile phone are equal to the embodiment.

The connection, the host-carrier-transmitting circuit 22, is disposed on the wheel of the transmitting end processor 21 for transmitting; the mountain-receiving circuit 23 is disposed at the other input end of the transmitting end processor 21 - to receive The receiving signal of each receiving device is returned; wherein: * i the transmitting end processor 21 has a transmitting end data transmission program built therein, although the digital wireless transmitter 2 () is connected with more than _ receiving devices 'The following steps will be performed (see ® 3): 'Load new data from host 1 terminal (301); add serial number (3〇2) to the loaded data to make the scheduled data sent in order; ^ Send the data of the added serial number (303); Receive the return confirmation signal (3〇4), and then judge whether all the receiving devices 30 that have been connected have returned the domain identification number (305); all the receiving devices 30 of the right have all Returning the confirmation signal, that is, returning to step (301) to repeat the preceding steps, if the receiving device 30 does not return the gift ID, return to step (303) 'to repeat the previous data. • Since the present invention allows two or more receiving devices 30 to simultaneously receive data transmitted by the digital wireless transmitter 2 with the same id, when any one of the packets is received, the data is received, so that the acknowledgement signal is not returned, the digit 8.201249117 The wireless transmitter 20 will repeatedly send the previous data, and the team will ensure that the connected receiving device 30 can receive the audio without interruption. Since the digital wireless transmitter 2 may repeatedly transmit the same serial number of data, the receiving device 3 has a corresponding design based on the requirements of normal and smooth reception. _Please refer to FIG. 4, which discloses a basic schematic diagram of receiving a shelf 3' which includes: a receiving end 31, having a - terminal and a (four) rounding end; a receiving circuit 32, a system The receiving end of the receiving end processor 31 is configured to receive the data sent by the digital wireless transmitter 2 (); a transmitting circuit 33 is disposed at an output end of the receiving end processor 31 for returning the acknowledgement The signal processing circuit 34 has a set of input terminals and a set of output terminals, wherein an input terminal is connected to the output end of the receiver processor 31, and an output terminal is connected to a group of racquets 35 for dialing and placing. The receiving end processor 31 has a receiving end data transmission program. When the receiving device 30 establishes a connection with the digital wireless transmitter 2, the following steps are performed (refer to FIG. 5): The receiving circuit 32 receives the data (5〇1); compares the data serial number (502), and further determines whether the serial number of the received data is repeated (503); the right data serial number is not repeated, that is, the data is output (5〇4) To the audio processing circuit 34 for conversion processing 'again Go to the team 35 to play; after the output of the data, then return the confirmation signal (505), and then return to the data step (501); 201249117 If the data serial number is repeated, discard the data (5〇6), then The return confirmation signal (505)' then returns to the receiving data step (5〇1). As described above, the present invention allows a digital wireless transmitter 2 to simultaneously transmit to four or more receiving devices (4) 'to ensure that all # receiving devices can receive data, and if any one of the receiving devices 3 is not After receiving the data without returning the confirmation signal, the digital wireless transmitter 2 will repeatedly send data to all (four) Μ 30 that have been connected to ensure data interruption occurs in all receiving devices 3... and for the normal signal The receiving device i 30 must respond to the repeated transmission of the digital wireless transmitter 2Q, so the receiving device S 3〇 and each data received by the receiving end data transmission program built in the receiving end processor 31 can receive Sorting according to the serial number, and comparing the data serial numbers to determine whether the serial number of the received data is repeated 'If the serial number of the received data is repeated, the data is discarded' to ensure the normal receiving of the receiving device 30. Please refer to @6*, the receiving device f3〇# audio processing circuit 34 may further be provided with a microphone 其中 on one of the input terminals for capturing sound through the microphone 36, and inputting the audio through the audio processing circuit 34.
