Then, the sequence number M is added to the Nth data strip, and the serial number M is used to indicate Sorting the Nth data strips in adjacent k data strips including the Nth data strip. For example, a frame flag bit may be added after each data strip, and the frame flag bit may be stored. The serial number, for example, the first to tenth data strips, the serial numbers are 10, 20, 30, 40, 50, 10, 20, 30, 40, 50, and the serial number of the second data strip 20 indicates the data strip. In the order of the adjacent five data strips, it should be noted that the serial number may be a specific order of numbers, symbols or letters, or a combination thereof, and the present invention is not limited.

[0075] 步骤 S103: 发送方将多个加入序号的数据条向接收方发送。 [0075] Step S103: The sender sends the data strips of the multiple join sequence numbers to the receiver.

[0076] 具体地，发送方将多个加入序号的数据条向接收方发送，其中发送方可以将加入序号的数据条一个一个的发送，接收方一个一个的接收和判断所接收的加入序号的数据条的顺序是否正确；发送方也可以连续发送 h个加入序号的数据条，接收方接收该 h加入序号的数据条后再判断接收的该 h个加入序号的数据条的顺序是否正确。 [0076] Specifically, the sender sends multiple data strips of the added sequence number to the receiver, where the sender can send the data strips of the join sequence number one by one, and the receivers receive and determine the received join sequence number one by one. The order of the data strips is correct; the sender may also continuously send h data strips with the serial number added, and the receiving party receives the data strip of the h join sequence number, and then determines whether the order of the received data strips of the added number is correct.

[0077] 步骤 S104: 接收方接收所述多个加入序号的数据条。 [0077] Step S104: The receiver receives the data strips of the multiple join sequence numbers.

[0078] 步骤 S105: 判断接收方接收多个加入序号的数据条的顺序与多个加入序号的数据条中的序号是否一致。 [0078] Step S105: It is determined whether the order in which the receiver receives the data strips of the plurality of join sequences is consistent with the sequence numbers in the data strips of the plurality of join sequence numbers.

[0079] 具体地，接收方判断接收方接收多个加入序号的数据条的顺序与多个加入序号的数据条中的序号是否一致。例如，假设第 1-10个数据条加入的序号分别为 a、 b、 c、 d、 e、 f、 g、 h、 ί、 j , 接收方接收该 10个加入序号的数据条的顺序为同样为 a、 b、 c、 d、 e、 f、 g、 h、 ί、 j , 则接收方接收多个加入序号的数据条的顺序与多个加入序号的数据条中的序号一致，否则上述判断结果为"否"。 [0079] Specifically, the receiving party determines whether the order in which the receiving party receives the data strips of the plurality of joining serial numbers is consistent with the sequence numbers in the data strips of the plurality of joining serial numbers. For example, suppose the numbers of the 1-10th data strips are a, b, c, d, e, f, g, h, ί, j, respectively. The order in which the receiver receives the data strips of the 10 join sequences is the same. For a, b, c, d, e, f, g, h, ί, j, the order in which the receiver receives the data strips of the multiple join sequence numbers is consistent with the sequence numbers in the data strips of the multiple join sequence numbers, otherwise the above judgment The result is "No".

[0080] 步骤 S106: 接收方请求发送方将出错的数据段重新发送。 [0080] Step S106: The receiver requests the sender to resend the erroneous data segment.

[0081] 具体地，当发送方是分批发送的加入序号的数据条，接收方是分配判断接收方接收该接批加入序号的顺序是否正确，如果接收方判断接收方接收该接批加入序号的顺序不正确，则接收方请求发送方将该批数据条重新发送，或者接收方储存该批数据条中正确的数据条，并请求发送方发送该正确的数据条之后的加入序号的数据条。 [0081] Specifically, when the sender is a data strip of a join sequence number sent in batches, the receiver is an allocation judgment receiver. The order of receiving the batch number is correct. If the receiver determines that the order of the receiver receiving the batch number is incorrect, the receiver requests the sender to resend the batch data strip, or the receiver stores the batch data strip. In the correct data strip, and request the sender to send the data strip after the correct data strip.

[0082] 上述发明，发送方将需要进行传输的数据段划分成多个数据条，并为多个数据条分别加入序号以获得多个加入序号的数据条，将所述多个加入序号的数据条向接收方发送，其中，第 N个数据条中加入序号 M, 序号 M用于表示第 N个数据条在包括第 N个数据条在内的相邻的 k个数据条中的排序；接收方接收该多个加入序号的数据条，并判断接收多个加入序号的数据条的顺序与多个加入序号的数据条中的序号是否一致，如果否，则请求发送方将出错的数据段重新发送。通过上述方法可以实现在使用蓝牙传输数据吋数据顺序的准确。 [0082] In the above invention, the sender divides the data segment that needs to be transmitted into a plurality of data strips, and adds a sequence number to the plurality of data strips to obtain a plurality of data strips with the added sequence number, and the plurality of data of the added sequence number The strip is sent to the receiver, wherein the number N is added to the Nth data strip, and the sequence number M is used to indicate the order of the Nth data strip in the adjacent k data strips including the Nth data strip; The party receives the data strips of the plurality of join sequence numbers, and determines whether the sequence of receiving the data strips of the plurality of join sequence numbers is consistent with the sequence numbers of the plurality of data strips of the join sequence number. If not, the request sender sends the data segment of the error again. send. Through the above method, the accuracy of the data sequence in the data transmission using Bluetooth can be realized.

[0083] 请参阅图 2, 图 2是本发明一种基于蓝牙的数据传输方法实施方式二的流程图。 Please refer to FIG. 2. FIG. 2 is a flowchart of Embodiment 2 of a Bluetooth-based data transmission method according to the present invention.

[0084] 步骤 S201: 发送方将需要进行传输的数据段划分成多个数据条。 [0084] Step S201: The sender divides the data segment that needs to be transmitted into multiple data strips.

[0085] 具体地，发送方通过蓝牙向接收方传输数据吋，一般地，接收方接收该传输数据先放在缓存中，当缓存内存达到一定量后再写入内存器中并储存该传输数据。由于缓冲内存容量和蓝牙传输的限制，当传输数据较大吋需要将该传输数据分批发送，发送方将需要进行传输的数据段划分成多个数据条。 [0085] Specifically, the sender transmits data to the receiver through the Bluetooth. Generally, the receiver receives the transmission data and first puts it in the cache. When the cache memory reaches a certain amount, the data is written into the memory and the transmission data is stored. . Due to the limitation of buffer memory capacity and Bluetooth transmission, when the transmission data is large, the transmission data needs to be sent in batches, and the sender divides the data segment that needs to be transmitted into multiple data strips.

[0086] 步骤 S202: 发送方为多个数据条分别加入序号以获得多个加入序号的数据条 [0086] Step S202: The sender adds a sequence number to the plurality of data strips respectively to obtain a plurality of data strips of the added sequence number.

[0087] 发送方向接收方依次发送数据条，对于接收方来说，接收方不能识别所接受的数据条的顺序是否正确，此吋在第 N个数据条中加入序号 M , 序号 M用于表示所述第 N个数据条在包括所述第 N个数据条在内的相邻的 k个数据条中的排序，例如，可以在每一个数据条后增加帧标志位，该帧标志位可以储存序号，比如，第 1至第 10个数据条，序号分别为 10、 20、 30、 40、 50、 10、 20、 30、 40、 50, 第二个数据条的序号 20序号则表示该数据条在相邻的 5个数据条中的排序，需要说明的是，序号可以为特定顺序的数字、符号或字母，或其组合，本分明不作限制。 [0088] 步骤 S203: 判断 N是否大于数据总条数。 [0087] The sending direction receives the data strips in sequence, and the receiving party cannot identify whether the order of the accepted data strips is correct for the receiving party, and then adds the serial number M to the Nth data strip, and the serial number M is used to indicate Sorting the Nth data strips in adjacent k data strips including the Nth data strip. For example, a frame flag bit may be added after each data strip, and the frame flag bit may be stored. The serial number, for example, the first to tenth data strips, the serial numbers are 10, 20, 30, 40, 50, 10, 20, 30, 40, 50, and the serial number of the second data strip 20 indicates the data strip. In the order of the adjacent five data strips, it should be noted that the serial number may be a specific order of numbers, symbols or letters, or a combination thereof, and the present invention is not limited. [0088] Step S203: Determine whether N is greater than the total number of data.

[0089] 具体地，当 N大于数据总条数，说明发送方已经将所需要传输的数据传输完成 [0089] Specifically, when N is greater than the total number of data, the sender has completed the transmission of the data to be transmitted.

, 则此吋传输数据结束。 , then the data transfer ends.

[0090] 步骤 S204: 发送方依次发送从第 N个数据条起的 h个加入序号的数据条。 [0090] Step S204: The sender sequentially sends h data strips of the join sequence number from the Nth data strip.

[0091] 具体地，发送方从 N=l幵始，将从第 1个数据起的 h个加入序号的数据条发送给接收方。 h不大于 k , 保证所发送的 h个数据条的序号各不相同，例如 h=4, 则发送方依次向接收方发送第 1个数据条、第 2个数据条、第 3个数据条、第 4个数据条。 [0091] Specifically, the sender starts from N=l, and sends h data strips of the join sequence number from the first data to the receiver. h is not greater than k, and the sequence numbers of the transmitted h data strips are guaranteed to be different. For example, h=4, the sender sequentially sends the first data strip, the second data strip, the third data strip, and the third data strip to the receiver. The fourth data bar.

[0092] 需要说明的是，当 N不大于数据总条数且 N+h大于数据总条数吋，说明此吋，发送方还未发送的数据条少于 h个，则发送剩余未发送的数据条。 [0092] It should be noted that, when N is not greater than the total number of data and N+h is greater than the total number of data, indicating that the sender has not sent more than h data strips, then the remaining unsent is sent. Data strip.

[0093] 步骤 S205: 接收方接收从第 N个数据条起的 h个加入序号的数据条。 [0093] Step S205: The receiver receives the data strips of the h join sequence numbers from the Nth data strip.

[0094] 具体地接收方接收发送方通过蓝牙发送的从第 N个数据条起的 h个加入序号的数据条，放入缓存中。例如接收方接收发送方通过蓝牙发送的第 1个数据条、第[0094] Specifically, the receiving party receives the data strips of the h joining sequence numbers from the Nth data strip sent by the sender through the Bluetooth, and puts them into the cache. For example, the receiver receives the first data strip sent by the sender via Bluetooth,

2个数据条、第 3个数据条、第 4个数据条。 2 data strips, 3rd data strip, 4th data strip.

[0095] 步骤 S206: 判断接收方接收的从第 N个数据条起的 h个加入序号的数据条的顺序是否正确。 [0095] Step S206: It is judged whether the order of the data strips of the h join sequence numbers received from the Nth data strip received by the receiver is correct.

[0096] 具体地，接收方判断比对序号的之后是否为接收方接收从第 N个数据条起的 h 个加入序号的数据条中首次接收的加入序号的数据条的序号，并且判断判断接收的从第 N个数据条起的 h个加入序号的数据条的顺序与该 h个加入序号的数据条中的序号是否一致，当两个判断结果都为 "是"吋，步骤 S206的判断结果才为"是 [0096] Specifically, the receiving party determines whether the sequence number of the comparison sequence is the number of the data strip of the join sequence number first received by the receiver in the data strip of the h join sequence number from the Nth data strip, and determines the judgment and reception. Whether the order of the h-added data strips from the Nth data strip is consistent with the sequence number of the h-joined data strips, and when both judgment results are "Yes", the judgment result of step S206 Only "is

[0097] 需要说明的是，当 N=l吋，即发送方首次发送数据，此吋接收方没有对比序号 [0097] It should be noted that when N=l吋, that is, the sender sends data for the first time, the receiver does not have a comparison sequence number.

, 此吋，只判断接收的从第 N个数据条起的 h个加入序号的数据条的顺序与该 h 个加入序号的数据条中的序号是否一致。例如，接收方接收的数据条的顺序为 1 Then, it is judged whether the order of the received data strips of the h-joined number from the Nth data strip is consistent with the sequence number of the h-joined data strips. For example, the order of the data strips received by the receiver is 1

0、 20、 30、 40与加入数据条的序号 10、 20、 30、 40、 50、 10、 20 是一致的0, 20, 30, 40 are consistent with the serial numbers 10, 20, 30, 40, 50, 10, 20 of the added data strip.

, 则上述判断结果为"是"，如果接收方接收的数据条的顺序为 10、 30、 20、 40 , 则上述判断结果为"否"。当上述判断结果为是吋，储存该 4个数据条，并将最后一个即第 4个数据条的序号 40作为对比序号。 [0098] 当 N〉 1吋，接收方还需要判断比对序号的之后是否为接收方接收从第 N个数据条起的 h个加入序号的数据条中首次接收的加入序号的数据条的序号。例如当 N= 5吋，第 5-9个数据条的序号分别为 50、 10、 20、 30, 如果接收方接收的数据条的顺序为 50、 10、 20、 30, 则对比序号 40之后为 50, 并且接收方接收的数据条的顺序 50、 10、 20、 30与加入数据条的序号的顺序一致，则上述判断结果为"是" , 否则，上述判断结果为"否"。 Then, the above judgment result is "Yes", and if the order of the data strips received by the receiver is 10, 30, 20, 40, the above judgment result is "No". When the above judgment result is 吋, the four data strips are stored, and the last one, that is, the serial number 40 of the fourth data strip is used as the comparison serial number. [0098] When N>1吋, the receiver further needs to determine whether the sequence number of the join sequence number of the first received sequence number in the data strip of the h join sequence number received from the Nth data strip is received by the receiver. . For example, when N=5吋, the numbers of the 5-9th data strips are 50, 10, 20, 30 respectively. If the order of the data strips received by the receiver is 50, 10, 20, 30, then the comparison number 40 is followed by 50, and the order of the data strips received by the receiver 50, 10, 20, 30 is the same as the order of the sequence numbers of the added data strips, the above judgment result is "Yes", otherwise, the above judgment result is "No".

[0099] 步骤 S207: 接收方储存该 h个加入序号的数据条中的 h个数据条并将第 N+h-1个数据条的序号作为比对序号。 [0099] Step S207: The receiver stores the h data strips in the data strips of the h join sequence numbers and uses the sequence numbers of the N+h-1 data strips as the comparison sequence numbers.

[0100] 当步骤 S206的判断结果才为"是"吋，则接收方接收的顺序正确，接收方储存该 h个加入序号的数据条中的 h个数据条，并将第 N+h-1个数据条的序号，即最后一个接收的加入序号的数据条的序号，作为比对序号，并且令 N=N+h。 [0100] When the result of the determination in step S206 is "YES", the order received by the receiver is correct, and the receiver stores the h data strips in the data strips of the h join sequence numbers, and the N+h-1 The serial number of the data strip, that is, the serial number of the last received data strip of the added serial number, as the comparison serial number, and let N=N+h.

[0101] 步骤 S208: 接收方请求发送方发送从第 N个数据条起 h个加入序号的数据条。 [0101] Step S208: The receiver requests the sender to send the data strips of the join sequence number from the Nth data strip.

[0102] 具体地，步骤 S206的判断结果才为"是"，则接收方接收的顺序正确， N=N+h [0102] Specifically, the determination result of step S206 is “Yes”, and the order received by the receiver is correct, N=N+h

, 接收方请求发送方继续发送加入序号的数据条；步骤 S206的判断结果才为"否 ", 则接收方接收的顺序出错， N不变，接收方请求发送方重新发送从第 N个加入序号的数据条。 The receiver requests the sender to continue to send the data strip of the join sequence number; if the judgment result of step S206 is "No", the order received by the receiver is wrong, N is unchanged, and the receiver requests the sender to resend the sequence number from the Nth join. Data strip.

[0103] 需要说明的是，本发明的另一种实施例中：步骤 S206也可以仅执行 "判断判断接收的从第 N个数据条起的 h个加入序号的数据条的顺序与从第 N个数据条起的 h 个加入序号的数据条中的序号是否一致"一种判断，步骤 S207也可以仅执行 "接收方储存该 h个加入序号的数据条中的 h个数据条"。 [0103] It should be noted that, in another embodiment of the present invention: Step S206 may also only perform "determining the order of determining the received data strips of the h join sequence numbers from the Nth data strip and from the Nth Whether the serial numbers in the h-added data strips from the data strips are consistent "A judgment, step S207 may also only execute "the recipient stores the h data strips in the h-joined data strips".

[0104] 上述发明，将数据分批发送分批判断接收方接收的从第 N个数据条起的 h个加入序号的数据条的顺序是否正确，如果是，则储存该 h个加入序号的数据条，请求发送方发送下一批加入序号的数据条，否则，请求发送方重新发送该 h个加入序号的数据条，通过该数据传输方法可以保证数据传输的顺序的准确。 [0104] In the above invention, the data is sent in batches to determine whether the order of the h numbered data strips received from the Nth data strip received by the receiver is correct, and if so, the data of the h join sequence numbers is stored. The requesting sender sends the next batch of data strips with the serial number. Otherwise, the requesting sender resends the h data strips with the serial number, and the data transmission method can ensure the accuracy of the data transmission sequence.

[0118] 步骤 S307: 接收方向发送方发送接收成功指令。 [0118] Step S307: The receiving direction sends a receiving success instruction to the sender.

[0119] 具体地，当接收方接收数据成功，即接收方将从第 N个数据起的 h个加入序号的数据条写入缓存，接收方向发送方发送接收成功指令，说明蓝牙连接正常，发送方可以继续向接受方传输数据。 [0119] Specifically, when the receiving party receives the data successfully, that is, the receiving party writes the h-added data strips from the Nth data into the buffer, and the receiving direction sends a receiving success instruction, indicating that the Bluetooth connection is normal, and the sending The party can continue to transfer data to the recipient.

[0120] 步骤 S308: 发送方判断在第一吋间阈值内是否收到接收成功指令。 [0120] Step S308: The sender determines whether a reception success instruction is received within the first inter-threshold threshold.

[0121] 具体地，如果发送方在第一吋间阈值内收到接收成功指令，说明蓝牙连接正常；如果发送方在第一吋间阈值内未收到接收成功指令，则说明蓝牙连接不稳定 , 请求发送方重新发送从第 N个数据起的 h个加入序号的数据条。该第一吋间阈值可以设置为 0.5s、 ls、 2s等，本发明不作限制。 [0121] Specifically, if the sender receives the reception success instruction within the first inter-threshold threshold, the Bluetooth connection is normal; if the sender does not receive the reception success instruction within the first inter-threshold threshold, the Bluetooth connection is unstable. , requesting the sender to resend the h-added data strips from the Nth data. The first inter-turn threshold may be set to 0.5s, ls, 2s, etc., and the invention is not limited.

[0122] 步骤 S309: 发送方判断在第二吋间阈值内是否收到接收成功指令。 [0122] Step S309: The sender determines whether a reception success instruction is received within the second time threshold.

[0123] 具体地，如果发送方在第二吋间阈值内收到接收成功指令，说明蓝牙连接正常；如果发送方在第二吋间阈值内未收到接收成功指令，则说明蓝牙连接中断。其中，第二吋间阈值大于第一吋间阈值，该第二吋间阈值可以设置为 2s、 3s、 5s 等，本发明不作限制。 [0123] Specifically, if the sender receives the reception success instruction within the second inter-threshold threshold, the Bluetooth connection is normal; if the sender does not receive the reception success instruction within the second inter-threshold threshold, the Bluetooth connection is interrupted. The second inter-turn threshold is greater than the first inter-threshold threshold, and the second inter-threshold threshold may be set to 2s, 3s, 5s Etc., the invention is not limited.

[0124] 步骤 S310: 发送方储存第 N个加入序号的数据条的数据信息。 [0124] Step S310: The sender stores the data information of the Nth data column of the added sequence number.

[0125] 具体地，如果发送方在第二吋间阈值内未收到接收成功指令，则说明蓝牙连接中断，此吋发送方储存第 N个加入序号的数据条的数据信息，该数据信息包括当前 N值以及第 N个数据条的序号，并暂停数据传输。 [0125] Specifically, if the sender does not receive the reception success instruction within the second inter-threshold threshold, the Bluetooth connection is interrupted, and the sender stores the data information of the Nth added sequence data strip, where the data information includes The current N value and the sequence number of the Nth data strip, and the data transmission is suspended.

[0126] 步骤 S311: 判断接收方接受的从第 N个数据条起的 h个加入序号的数据条顺序是否正确。 [0126] Step S311: It is determined whether the order of the data strips of the h joining sequence numbers received from the Nth data strip accepted by the receiver is correct.

[0127] 具体地，接收方判断比对序号的之后是否为接收方接收的从第 N个数据条起的 h个加入序号的数据条中首次接收的加入序号的数据条的序号，按照接收顺序依次判断接收方接收的从第 N个数据条起的 h个加入序号的数据条的序号是否为前一个接收的加入序号的数据条中的序号之后的序号。例如，当 N=5吋，如果接收方接收的数据条的顺序为 50、 10、 20、 30, 对比序号 40之后的序号 50与首次接收的加入序号的数据条的序号 50—致，并且，首次接收的数据条是序号 50之后的序号 10与第 2个接收的数据条的序号 10—致，依次类推，第 3个接收的数据条的序号 20之后的序号 30与第 4个接收的数据条的序号 30—致，则上述判断结果为 "是"，否则，上述判断结果为"否"。 [0127] Specifically, the receiving party determines whether the sequence number of the sequence number of the first number of the data sequence of the number of the join number received from the Nth data strip received by the receiver after the comparison sequence number is received, in the order of receiving It is sequentially determined whether the sequence number of the h number-added data strips received from the Nth data strip received by the receiver is the sequence number after the serial number in the data strip of the previous received join sequence number. For example, when N=5吋, if the order of the data strips received by the receiver is 50, 10, 20, 30, the serial number 50 after the comparison number 40 is the same as the sequence number 50 of the data strip of the first received join sequence number, and The data strip received for the first time is the serial number 10 after the serial number 50 and the serial number 10 of the second received data strip, and so on, and the serial number 30 and the fourth received data after the serial number 20 of the third received data strip. If the serial number of the bar is 30, the above judgment result is "Yes", otherwise, the above judgment result is "No".

[0128] 步骤 S312: 接收方储存该 h个加入序号的数据条中的 h个数据条并将将最后一个接收的数据条的序号作为比对序号。 [0128] Step S312: The receiver stores the h data strips in the h data strips of the join sequence number and uses the sequence number of the last received data strip as the comparison sequence number.

[0129] 具体地，当步骤 S312的判断结果才为"是"吋，则接收方接收的顺序正确，接收方储存该 h个加入序号的数据条中的 h个数据条，并将第 Ν+h-l个数据条的序号，即最后一个接收的加入序号的数据条的序号，作为比对序号，并且令 N=N+h。 [0129] Specifically, when the result of the determination in step S312 is “Yes”, the order received by the receiver is correct, and the receiver stores the h data strips in the data strips of the h join sequence numbers, and the third data is The sequence number of the hl data strips, that is, the sequence number of the last received data strip of the added sequence number, as the comparison sequence number, and let N=N+h.

[0130] 步骤 S313: 接收方请求发送方发送从第 N个加入序号的数据条。 [0130] Step S313: The receiver requests the sender to send the data strip from the Nth join sequence number.

[0131] 步骤 S314: 接收方储存正确的数据条以及对比序号。 [0131] Step S314: The receiver stores the correct data strip and the comparison sequence number.

[0132] 具体地，当步骤 S311的判断结果为 "否"吋，接收方储存从第 N个数据条起的 h 个加入序号的数据条中正确的数据条并将最后一个正确的数据条的序号作为比对序号。比如，当 N=5吋，如果接收方接收的数据条的顺序为 50、 20、 10、 30, 则从第 2个接收的数据条的序号 20出错，接收方储存首次接收的数据条 50, 以及将最后一个正确的数据条的序号 50以及对比序号。 [0133] 步骤 S315: 接收方请求发送方发送第 N+h-1个加入序号的数据条。 [0132] Specifically, when the result of the determination in step S311 is "NO", the receiver stores the correct data strip in the data strip of the h join sequence numbers from the Nth data strip and the last correct data strip The serial number is used as the comparison serial number. For example, when N=5吋, if the order of the data strips received by the receiver is 50, 20, 10, 30, the serial number 20 of the data strip received from the second one is in error, and the receiver stores the data strip 50 received for the first time. And the serial number 50 of the last correct data strip and the comparison number. [0133] Step S315: The receiver requests the sender to send the data strip of the N+h-1th join sequence number.

[0134] 步骤 S316: 发送方发送 N+h-1个加入序号的数据条。 [0134] Step S316: The sender sends N+h-1 data strips with the added sequence number.

[0135] 步骤 S317: 接收方接收第 N+h-1个数据条加入序号的数据条。 [0135] Step S317: The receiver receives the data strip of the sequence number of the N+h-1 data strips.

[0136] 步骤 S318: 判断接收方接收的第 N+h-1个加入序号的数据条的序号是否为比对序号的下一个序号。 [0136] Step S318: It is determined whether the sequence number of the data strip of the N+h-1th join sequence number received by the receiver is the next sequence number of the comparison sequence number.

[0137] 步骤 S319: 接收方储存第 N+h-1个数据条以及将第 N+h-1个数据条序号作为比对序号。 [0137] Step S319: The receiver stores the N+h-1 data strips and the N+h-1 data strip numbers as the comparison sequence numbers.

[0138] 具体地，如果步骤 S318的判断结果为"是"，则数据传输在第 N+h-1个数据条处出错，此吋接收方储存第 N+h-1个数据条，将第 N+h-1个数据条序号作为比对序号，并且另 N=N+h, 请求发送方发送从第 N个数据条起的 h个加入序号的数据条 [0138] Specifically, if the result of the determination in step S318 is YES, the data transmission is in error at the N+h-1th data strip, and the 吋 receiver stores the N+h-1th data strip, N+h-1 data strip numbers are used as alignment numbers, and another N=N+h, requesting the sender to send h join sequence data strips from the Nth data strip

[0139] 上述发明，通过将数据分批发送并逐个判断接收方接收的从第 N个数据条起的 h个加入序号的数据条的顺序是否正确，如果接收方接收的从第 N个数据条起的 h 个加入序号的数据条的顺序都正确，则储存该 h个加入序号的数据条以及将最后一个接收的数据条的序号作为比对序号，令^^1 , 请求发送方发送下一批加入序号的数据条，否则，储存正确的数据条以及将最后一个正确的数据条的序号作为比对序号，并请求发送方发送第 N+h-1个加入序号的数据条并判断接收的该第 N+h-1个加入序号的数据条的序号是否正确，如果是，则储存该数据条以及将概述具体的序号作为比对序号， 4N=N+1 , 请求发送方发送下一批加入序号的数据条，否则，令 N=N-1 , 重复请求发送方发送第 N+h-1个加入序号的数据条并判断。通过该数据传输方法可以保证数据传输的顺序的准确，而且，还可以实现蓝牙端点续传的功能。 [0139] According to the above invention, the data is sent in batches and judged one by one whether the order of the h-joined data strips received from the Nth data strip received by the receiver is correct, if the receiving party receives the Nth data strip The sequence of the h data columns added with the serial number is correct. The data strips of the h join sequence numbers are stored, and the sequence number of the last received data strip is used as the comparison sequence number, so ^^1, the request sender sends the next The data strip of the serial number is added in batches. Otherwise, the correct data strip is stored and the sequence number of the last correct data strip is used as the comparison sequence number, and the sender is requested to send the data strip of the N+h-1 join sequence number and judge the received data. Whether the sequence number of the data strip of the N+h-1th join sequence number is correct, if yes, the data strip is stored and the specific sequence number is used as the comparison sequence number, 4N=N+1, and the request sender sends the next batch. Add the data strip of the sequence number, otherwise, let N=N-1, repeat the request sender to send the N+h-1 data strip of the join sequence number and judge. Through the data transmission method, the order of data transmission can be ensured accurately, and the function of continuing the transmission of the Bluetooth endpoint can also be realized.
