In this embodiment, when the consumer machine starts to upload data, the application layer of the consumer machine splits data to be transmitted into packets and transmits the packets through the transmission layer. Each packet data consists of a packet header, data, a CRC check word and a packet tail. The head and tail of the packet are a fixed segment of data; the CRC check word is used to check the packet data. Similarly, the terminal transmits the data to the application layer after the data is successfully received by the transmission layer. The application layer firstly unpacks the received data, judges whether the head and the tail of the packet are correct, judges whether the CRC check is correct and judges whether the format of the data is correct. If the application layer of the terminal unpacks the packet, the packet header, the packet tail, the CRC check and any field data in the data are incorrect, the data are judged to be unpacked failure, namely data transmission error; similarly, when the consumer receives the response signal data returned by the terminal, the application layer of the consumer first unpacks the received response signal data, determines whether the header and the trailer are correct, determines whether the CRC check is correct, and determines whether the format of the data is correct. If the application layer of the consumer machine unpacks the packet, the packet header, the packet tail, the CRC check, and any field data in the data are incorrect, the unpacking is judged to be a failure, that is, a data transmission error.
In this embodiment, without considering the case of data transmission error, it is assumed that the consumer computer can unpack successfully when receiving the response signal data returned by the terminal and the terminal receives the data to be sent by the consumer computer, that is, the packet header, the packet trailer, the CRC check, and any field data in the data are correct, and the flow of the data processing method is specifically as follows:
1. the consumption machine starts to send data to be sent, and after the application layer of the consumption machine sends a packet of data, the consumption machine enters a receiving state and waits for the terminal to return a response signal data packet. And starts a countdown waiting for reception.
(1) If the consumer machine is sending a packet of data, it has not yet been completely transmitted to the terminal, but the transmission medium is suddenly disconnected. At this time, the transmission layer of the terminal stops receiving due to the fact that data cannot be received;
(2) the application layer of the terminal does not return a response signal data packet to the consumer because the application layer does not receive any data sent by the transmission layer;
(3) the transmission layer of the consumer does not receive any data, and the application layer waits for a period of time before the countdown time is over. The application layer judges that the communication is overtime because no data is received, and then the communication is ended;
(4) at this point there is no loss or duplication of data.
2. After the transmission layer of the terminal successfully receives the data sent by the consumer, the data are transmitted to the application layer, the application layer can store the data, at the moment, the application layer of the terminal can send a response signal data packet to the consumer through the transmission layer, then the application layer enters a receiving state, waits for receiving the next packet of data, and starts a countdown waiting for receiving.
(1) If the terminal sends a response signal data packet to the consumer, the transmission medium is suddenly disconnected, the transmission layer of the consumer stops receiving due to no data being received, and the application layer does not receive any data sent by the transmission layer;
(2) after waiting for a period of time, the application layer of the consumer computer judges that the communication is overtime because no response is received, and then the communication is ended;
(3) similarly, the transmission layer of the terminal does not receive the next packet of data sent by the consumer, and after the countdown of the application layer is finished, the communication is judged to be overtime because no data is received, and then the communication is finished;
(4) at this time, the data in the packet exists in the consumer computer and the upper computer at the same time, and repeated data segments appear.
3. After receiving the response signal data packet, the transmission layer of the consumer machine transmits the response signal data packet to the application layer. The application layer cancels the countdown when receiving the response signal packet.
(1) If the consumption machine is down after the transmission layer of the consumption machine receives a packet of response signal data packet or during the receiving process, the consumption machine loses the communication capability, and the communication is directly finished;
(2) the terminal judges that the communication is overtime because no data is received after the countdown of the application layer of the terminal is finished because the transmission layer does not receive the next packet of data sent by the consumer, and then the communication is finished;
(3) at this time, the packet data exists in the consumer computer and the upper computer at the same time, and repeated data segments appear.
4. And after receiving the response signal data packet, the application layer of the consumer machine judges that the terminal has successfully received the last packet of data. Thus, the consuming machine deletes the last packet of data sent from the consuming machine.
(1) If the consumer machine is down after deleting the previous packet of data, the consumer machine directly finishes the communication;
(2) the terminal judges that the communication is overtime because no data is received after the countdown of the application layer of the terminal is finished because the transmission layer does not receive the next packet of data sent by the consumer, and then the communication is finished;
(3) at this point there is no loss or duplication of data.
5. And the application layer of the consumer computer can judge whether data which needs to be sent still exist after receiving the response signal data packet, and if the data which needs to be sent do not exist, the application layer of the consumer computer can send an empty data packet and transmit the empty data packet to the terminal through the transmission layer.
6. And after receiving the empty data packet, the transmission layer of the terminal transmits the empty data packet to the application layer. And the application layer cancels the countdown when receiving the empty data packet, and simultaneously, the application layer of the terminal judges that the data is completely received after receiving the empty data packet, sends a response signal data packet and sends the response signal data packet to the consumer machine through the transmission layer. The application layer then ends the communication.
7. The transmission layer of the consumer machine receives the response signal data packet of the null data packet and then transmits the response signal data packet to the application layer. And when the application layer receives the response signal data packet of the null data packet, the countdown is cancelled, and the communication is ended.
In this embodiment, if a data transmission error is considered, it is assumed that when the consumer receives the response signal data returned by the terminal and the terminal receives the data to be transmitted sent from the consumer, an unpacking failure may occur, that is, a packet header, a packet trailer, a CRC check, and any field data in the data are incorrect in the data packet, and both the unpacking failure and the data transmission error are determined. At this time, the data processing method flow refers to fig. 3, fig. 3 is one of the processing flows of the data processing method according to an embodiment of the present invention, and the flow specifically includes:
1. the consumer machine starts to send data, and after the application layer of the consumer machine sends a packet of data, the consumer machine enters a receiving state, waits for a response packet to be returned, and starts a countdown waiting for receiving.
(1) If the consumer machine is sending this packet of data, it has not yet been completely transmitted to the terminal, but the transmission medium is suddenly disconnected. At this time, the transmission layer of the terminal stops receiving due to the fact that data cannot be received;
(2) the application layer of the terminal does not return a response signal data packet to the consumer because the application layer does not receive any data sent by the transmission layer;
(3) the transmission layer of the consumer does not receive any data, and the application layer waits for a period of time before the countdown time is over. The application layer judges that the communication is overtime because no data is received, and then the communication is ended;
(4) at this point there is no loss or duplication of data.
2. After the transmission layer of the terminal successfully receives the packet data, the packet data is transmitted to the application layer, and the application layer firstly carries out unpacking processing on the received packet data, judges whether the packet head and the packet tail are correct, judges whether CRC (cyclic redundancy check) is correct and judges whether the format of the data is correct.
(1) If the application layer of the terminal unpacks the packet, the packet header, the packet tail, the CRC check and any field data in the data are incorrect, the data are judged to be unpacked failure, namely data transmission error; at this time, the application layer of the terminal discards the received data, and then, the application layer of the terminal sends an analysis failure response packet to the consumer machine through the transport layer. The application layer enters a receiving state, waits for receiving the packet data again, and starts a countdown waiting for receiving;
(2) and after receiving the response packet of the analysis failure, the transmission layer of the consumer machine transmits the response packet to the application layer. And after receiving the analysis failure response packet, the application layer cancels the receiving countdown and then analyzes the analysis failure response packet. After successful analysis, whether three times of failed analysis response packets are received or not is judged, and if not, the data of the packets are retransmitted. If the application layer of the consumer machine recognizes that the analysis failure response packet is received for three times continuously, the transmission failure is judged, and then the communication is ended;
(3) the application layer of the terminal judges that the receiving is overtime because the receiving countdown is finished and no receiving exists, and then the communication is finished;
(4) at this point there is no loss or duplication of data.
3. After the application layer of the terminal is unpacked successfully, data can be extracted and stored in a database, and then the application layer of the terminal can send a response signal data packet to the consumer through the transmission layer; the application layer of the terminal enters a receiving state, waits for receiving the next packet of data, and starts a countdown waiting for receiving.
(1) If the terminal returns a response signal packet to the consumer, the transmission medium is suddenly disconnected. The transmission layer of the consumer computer stops receiving due to the fact that the data cannot be received, and the application layer of the consumer computer does not receive any data sent by the transmission layer;
(2) after waiting for a period of time, the application layer of the consumer computer judges that the communication is overtime because no response is received, and then the communication is ended;
(3) similarly, the transmission layer of the terminal does not receive the next packet of data sent by the consumer, and after the countdown of the application layer is finished, the communication is judged to be overtime because no data is received, and then the communication is finished;
(4) at this time, the packet data exists in the consumer computer and the upper computer at the same time, and repeated data segments appear.
4. After receiving the response signal data packet, the transmission layer of the consumer machine transmits the response signal data packet to the application layer. The application layer cancels the countdown when receiving the response signal data packet;
(1) if the transmission layer of the consumer is down after receiving the response signal data packet or during receiving, the consumer loses the communication capability and directly finishes the communication;
(2) the terminal judges that the communication is overtime because no data is received after the countdown of the application layer of the terminal is finished because the transmission layer does not receive the next packet of data sent by the consumer, and then the communication is finished;
(3) at this time, the packet data exists in the consumer computer and the upper computer at the same time, and repeated data segments appear.
5. And after receiving the response signal data packet, the application layer of the consumer computer analyzes the response signal data packet.
(1) If the application layer of the consumer computer unpacks the packet, the packet head, the packet tail, the CRC check and any field data in the data are incorrect, the packet unpacking is judged to be failed, namely, the data transmission is wrong; at this time, the application layer of the consumer machine discards the received data; then, the application layer of the consumer computer sends an analysis failure response packet to the terminal through the transmission layer, the application layer enters a receiving state, waits for receiving the response signal data packet again, and starts a countdown waiting for receiving;
(2) and after receiving the analysis failure response packet, the application layer cancels the receiving countdown and then analyzes the analysis failure response packet. After successful analysis, whether the failure response packet is received three times continuously is judged. If not, the response signal data packet is retransmitted; if the application layer of the terminal recognizes that the analysis failure response packet is received for three times continuously, the transmission failure is judged, and then the communication is ended;
(3) at this time, the application layer of the consumer machine judges that the receiving is overtime because the receiving countdown is finished and no receiving is carried out, and then the communication is finished;
(4) at this time, the packet data exists in the consumer computer and the upper computer at the same time, and repeated data segments appear.
6. If the application layer of the consumer machine successfully analyzes the response signal data packet, the terminal is judged to successfully receive the last packet of data; thus, the consuming machine deletes the previous packet of data from the consuming machine.
(1) If the consumer machine is down after deleting the previous packet of data, the consumer machine directly finishes the communication;
(2) the terminal judges that the communication is overtime because no data is received after the countdown of the application layer of the terminal is finished because the transmission layer does not receive the next packet of data sent by the consumer, and then the communication is finished;
(3) at this point there is no loss or duplication of data.
7. The application layer of the consumer machine can judge whether data which needs to be sent exist, if the data which needs to be sent do not exist, the application layer of the consumer machine can send a null data packet, and the null data packet is transmitted to the terminal through the transmission layer.
8. After receiving the empty data packet, the transmission layer of the terminal transmits the empty data packet to the application layer, and the application layer cancels the countdown when receiving the empty data packet; and then the application layer of the terminal unpacks the data packet, after the unpacking is successful, the data is judged to be completely received, a response signal data packet is returned and sent to the consumer machine through the transmission layer, and then the application layer finishes the communication.
9. The transmission layer of the consumer receives the post-acknowledgement signal data packet and transmits the post-acknowledgement signal data packet to the application layer. The application layer cancels the countdown when receiving the packet; then, the application layer of the consumer computer unpacks the response signal data packet, and after the unpacking is successful, the communication is also ended.
10. A complete transmission is thus completed.
In summary, the data processing method described in this embodiment has the following advantages:
the embodiment of the invention provides a data processing method, which can solve the problem of data loss caused by communication interruption and the like when a consumer computer uploads data; the method sets a countdown for waiting to receive response signal data at the consumer side, so that when the response signal data is not successfully received, the communication can be ended when the countdown for waiting to receive the response signal data is ended; setting a countdown waiting for receiving next data to be sent at a terminal side for receiving the consumer data, so that the communication can be ended when the countdown waiting for receiving the next data to be sent is ended when the next data to be sent is not successfully received; and further, the data uploaded by the consumer computer can be judged not to be successfully uploaded, and the data loss of the consumer computer in the data uploading process is prevented.
