[0041] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0042] It should be noted that in any embodiment of the present invention, the data transmission method actively stores data through a local database when a data transmission failure occurs, and then transmits the data when the transmission conditions are restored, rather than transmitting data offline when the software downloads data, by storing a link to the download target address; therefore, the data transmission of the present application has good reliability, and the reliability of the transmission does not depend on the network protocol.

[0043] Reference Figure 1 , shows a data transmission method provided by an embodiment of the present application, the method is used to control the local end to continue to transmit data to the receiving end when the transmission is interrupted;

[0044] The method comprises:

[0045] S110, when data transmission occurs, adding a first time mark to the target data according to the system clock of the receiving end, and generating a first clock deviation table according to the local clock and the system clock of the receiving end;

[0046] S120: If the transmission process is interrupted, obtain the first time point of the interruption according to the local clock;

[0047] S130, adding a second time mark to the remaining target data according to the local clock and the first time point, and continuing to store the remaining target data in the local database;

[0048] S140. When the transmission condition is restored, the time parameters when the receiving end stops receiving the target data are calibrated according to the first time point, the first time mark, the second time mark and the first clock deviation table, and the remaining target data remaining in the local database is sent to the receiving end according to the time parameters.

[0049] In an embodiment of the present application, when data transmission is interrupted by the above method, the data is temporarily stored in a local database, and after the transmission conditions are restored, the data in the local database is automatically resumed according to the interruption time point, thereby preventing data loss and data errors caused by breakpoint transmission, and improving transmission efficiency; and after the data is stored in the local database, when the transmission conditions are restored, the data in the local database is transmitted to the receiving end without manual intervention, thereby realizing automatic resumption of data transmission.

[0050] Next, a data transmission method in this exemplary embodiment will be further described.

[0051] As described in step S110, when data transmission occurs, a first time mark is added to the target data according to the system clock of the receiving end, and a first clock deviation table is generated according to the local clock and the system clock of the receiving end.

[0052] In one embodiment of the present invention, when data transmission occurs in step S110, before adding a first time mark to the target data according to the system clock of the receiving end and generating a first clock deviation table according to the local clock and the system clock of the receiving end, the method further includes:

[0053] Acquire the system clock of the receiving end; divide the target data into a plurality of data blocks according to the format of the target data, and put the data blocks into a preset sending queue.

[0054] It should be noted that the data format is a rule that describes how data is stored in a file or record. It can be a text format in the form of characters, or a compressed format in the form of binary data. The text format in the form of characters takes up more storage space but has high transparency, while the compressed format in the form of binary numbers takes up less storage space but lacks transparency.

[0055] In the above embodiment, when data needs to be transmitted, the system clock of the receiving end (the target of data transmission, such as a server) is obtained according to the communication with the receiving end;

[0056] According to the format of the target data, for example, the target data is divided into data blocks using several hexadecimal units as basic units, and the divided data blocks are stored in a set sending queue. The data to be sent to the receiving end is managed through the sending queue. In case of an interruption, the breakpoint time and the position of the breakpoint of the data to be sent can be determined according to the minimum unit of the sending queue. Dividing the data blocks can further prevent the interruption of the data transmission process and the loss of data.

[0057] In one embodiment of the present invention, the specific process of step S110 "when data transmission occurs, adding a first time mark to the target data according to the system clock of the receiving end, and generating a first clock deviation table according to the local clock and the system clock of the receiving end" can be further explained in combination with the following description.

[0058] As described in the following steps, when data transmission occurs, a first time mark for recording the transmission time is added to each data block of the target data according to the system clock of the receiving end;

[0059] As described in the following steps, a first clock deviation table is generated according to the running time deviation between the local clock and the system clock of the receiving end.

[0060] In the above embodiment, a first time mark for recording the sending time is added to the data block, so that the sending time point of each data block can be recorded. When the data transmission is interrupted, the position and time of the data interruption point can be accurately determined through the first time point; a first time deviation table is established through the time deviation between the local clock and the receiving end system clock. Through the first time deviation table, the time parameters of the same data at the receiving end can be obtained, and the data can be verified and checked according to the time deviation table to ensure the accuracy of the data.

[0061] It should be noted that the so-called system clock refers to the clock system, which is a circuit composed of an oscillator (signal source), a timer wake-up device, a frequency divider, etc. Common signal sources include crystal oscillators and RC oscillators. The clock is the pulse of the embedded system. The processor core completes instruction execution, state change and other actions under the drive of the clock. The peripheral components complete various tasks under the drive of the clock, such as serial port data transmission, A / D conversion, timer counting, etc. Therefore, the clock is crucial to the computer system. Usually, problems with the clock system are fatal, such as the oscillator not oscillating, unstable oscillation, and stopped oscillation.

[0062] As described in step S120, if the transmission process is interrupted, the first time point of the interruption is obtained according to the local clock.

[0063] In an embodiment of the present invention, the specific process of step S120 is "if the transmission process is interrupted, obtaining the first time point of the interruption according to the local clock".

[0064] As described in the following steps, if the transmission process is interrupted, the preset network parameters are used to determine the node where the interruption occurs, wherein the node includes a network node, a receiving end node, and a local end node;

[0065] As described in the following steps, an NTP clock is obtained, and a second clock deviation table is generated according to the local clock and the NTP clock;

[0066] As described in the following steps, when the interruption occurrence node is a network node and / or a receiving end node, the first time point when the interruption occurs is obtained based on the local clock, or, when the interruption occurrence node is a local end node, the first time point when the interruption occurs is obtained based on the NTP clock and the second clock deviation table.

[0067] In the above embodiment, if the transmission process is interrupted, the preset network parameters are used to determine the node where the interruption occurs, wherein the nodes include network nodes, receiving end nodes, and local end nodes; for example, whether the target end is normal is determined by the return data of the target end, and whether the network is normal is determined by network parameters such as the return value of the PING network; the NTP clock is obtained through the network, and a second clock deviation table between the local clock and the NTP clock is generated based on the local clock.

[0068] It should be noted that the NTP clock is a network clock provided by the NTP server. The NTP server (Network Time Protocol (NTP)) is a protocol used to synchronize computer time. It can synchronize computers with their servers or clock sources (such as quartz clocks, GPS, etc.). It can provide high-precision time correction (the difference with the standard is less than 1 millisecond on LAN and tens of milliseconds on WAN), and can prevent malicious protocol attacks through encryption confirmation. Time is propagated according to the level of the NTP server. All servers are classified into different Stratums according to their distance from the external UTC source.

[0069] In order for NTP to provide accurate time, it must first have an accurate time source, which should be the international standard time UTC. The time source for NTP to obtain UTC can be atomic clocks, observatories, satellites, or the Internet. In this way, there is an accurate and reliable time source. Time is propagated according to the level of the NTP server. All servers are classified into different Stratums (layers) according to their distance from the external UTC source. Stratum-1 is at the top level and has external UTC access, while Stratum-2 obtains time from Stratum-1, Stratum-3 obtains time from Stratum-2, and so on, but the total number of Stratum layers is limited to 15. All these servers logically form a ladder-like architecture that is interconnected, and the Stratum-1 time server is the foundation of the entire system.

[0070] As described in step S130, a second time stamp is added to the remaining target data according to the local clock and the first time point, and the remaining target data is stored in the local database.

[0071] In one embodiment of the present invention, the specific process of "adding a second time mark to the remaining target data according to the local clock and the first time point, and continuing to store the remaining target data in the local database" in step S130 can be further explained in combination with the following description.

[0072] As described in the following steps, adding a second time stamp for recording the local storage time to the remaining target data according to the local clock and the first time point;

[0073] As described in the following steps, the remaining target data is stored in the local database according to the second time stamp.

[0074] In the above embodiment, after the transmission is interrupted, since the system clock of the receiving end may not be available, a second time stamp may be added to the data after the interruption through the local clock to record the time of the data stored in the local database.

[0075] In one embodiment of the present invention, the specific process of step S140 described in "When the transmission condition is restored, calibrate the time parameters when the receiving end stops receiving the target data according to the first time point, the first time mark, the second time mark and the first clock deviation table, and send the remaining target data continuing to exist in the local database to the receiving end according to the time parameters" can be further explained in combination with the following description.

[0076] As described in the following steps, when the transmission condition is restored, a second time point when the transmission of the target data is stopped is determined according to the timing difference between the first time mark and the second time mark;

[0077] As described in the following steps, calibrating the second time point according to the first clock deviation table and the first time point;

[0078] As described in the following steps, the remaining target data stored in the local database is sent to the receiving end according to the calibrated second time point.

[0079] In the above embodiment, after the transmission condition is restored, the first time deviation table, the first time point and the second time point are calibrated to ensure that the data before and after the interruption can be correctly connected, thereby ensuring the accuracy of the data.

[0080] In one embodiment of the present invention, the method further includes: if the transmission condition is not satisfied, compressing and encrypting the remaining target data stored in the local database.

[0081] In the above embodiment, when the transmission is interrupted and the transmission conditions are not restored, the target data is compressed when stored in the local database, thereby saving storage space, and compressing the data can prevent data overflow caused by excessive storage of data; the security of the data is ensured by encrypting the data; after the transmission conditions are restored, the data is decompressed for transmission.

[0082] As for the device embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
