[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0041] Embodiment 1

[0042] Figure 1 It is a flowchart of a data transmission method provided in Embodiment 1 of the present invention. This embodiment is applicable to data transmission in the Internet of Things. This method can be executed by a data transmission device, and the device can be implemented in software and / or hardware and can be configured in an electronic device with a data transmission function.

[0043] See Figure 1 The data transmission method shown is applied to a client and includes:

[0044] S110. Obtain the data to be synchronized, and update the data to be synchronized according to a preset sorting strategy to obtain the current synchronized data.

[0045] Among them, the data to be synchronized refers to the data that needs to be synchronously stored between the client and the server. The present invention does not make any limitation on the form of the data to be synchronized. Exemplarily, the data to be synchronized can be displayed in the form of characters, that is, the data to be synchronized can be a string.

[0046] Among them, the preset sorting strategy refers to a strategy that is preset and can be used to sort each sub-data in the data to be synchronized. Exemplarily, the preset sorting strategy can be a dictionary sorting strategy. Specifically, according to the dictionary sorting strategy, the keys in the data to be synchronized can be sorted to update the data to be synchronized to obtain the current synchronized data. It should be noted that the key-value pairs included in the current synchronized data are the same as those in the data to be synchronized. By using the preset sorting strategy, the keys in the data to be synchronized are re-sorted to adjust the positions of the key-value pairs in the data to be synchronized to obtain the current synchronized data.

[0047] Among them, the current synchronized data refers to the data obtained after updating the data to be synchronized according to the preset sorting strategy.

[0048] Specifically, the client obtains the data to be synchronized, sorts the keys in the data to be synchronized according to a preset sorting strategy, and obtains the current synchronized data.

[0049] S120. Determine the current data structure of the current synchronized data, and determine whether there is candidate historical synchronized data under the current data structure.

[0050] Among them, the current data structure refers to the data structure of the current synchronized data, that is, the data structure of the data to be synchronized. Exemplarily, there are multiple candidate data structures in the client, and the current data structure of the data to be synchronized is determined from the candidate data structures. The candidate data structure refers to the data structures pre-stored in the client.

[0051] Among them, the candidate historical synchronized data refers to the synchronized data that has been stored in both the client and the server and belongs to the current data structure.

[0052] Specifically, the client determines the current data structure of the current synchronized data, and determines whether there is already candidate historical synchronized data under the current data structure, that is, determines whether the current synchronized data is the first synchronized data belonging to the current data structure.

[0053] S130. If there is, determine the reference historical synchronized data from the candidate historical synchronized data, and determine the current transmission data corresponding to the current synchronized data according to the reference historical synchronized data and the current synchronized data.

[0054] Among them, the current transmission data includes the reference data identifier of the reference historical synchronized data and the difference associated data.

[0055] Among them, the reference historical synchronized data refers to the candidate historical synchronized data with a smaller difference from the current synchronized data. Preferably, the reference historical synchronized data can be the candidate historical synchronized data with the smallest difference from the current synchronized data.

[0056] Exemplarily, determine the data similarity between each candidate historical synchronized data and the current synchronized data respectively; determine the reference historical synchronized data from the candidate historical synchronized data according to the data similarity. Among them, the data similarity can be used to quantify the similarity degree between the candidate historical synchronized data and the current synchronized data.

[0057] Among them, the current transmission data refers to the data sent by the client to the server. The reference data identifier can uniquely represent the identity of the reference historical synchronized data. The difference associated data refers to the associated data with differences between the current synchronized data and the reference historical synchronized data.

[0058] Specifically, if there is candidate historical synchronization data in the current data structure, the client determines the reference historical synchronization data with the smallest difference from the current synchronization data among the candidate historical synchronization data; compares the reference historical synchronization data with the current synchronization data to determine the difference-related data; and determines the current transmission data based on the reference data identifier of the reference historical synchronization data and the difference-related data.

[0059] S140. Send the current transmission data to the server so that the server generates and stores the current synchronization data based on the current transmission data and the candidate historical synchronization data, and determines the current data identifier of the current synchronization data.

[0060] Among them, the current data identifier can uniquely represent the identity of the current synchronization data.

[0061] Specifically, the client sends the current synchronization data to the server; the server generates the current synchronization data based on the current synchronization data and the stored candidate historical synchronization data; the server determines the current data identifier of the current synchronization data, and stores the current synchronization data and the current data identifier in correspondence; the server sends the current data identifier to the client.

[0062] S150. Receive the current data identifier fed back by the server, and store the current synchronization data and the current data identifier.

[0063] Specifically, the client receives the current data identifier fed back by the server; the client stores the current synchronization data and the current data identifier in correspondence.

[0064] An embodiment of the present invention provides a data transmission solution. By obtaining data to be synchronized and updating the data to be synchronized according to a preset sorting strategy, the current synchronized data is obtained; determining the current data structure of the current synchronized data, and determining whether there is candidate historical synchronized data under the current data structure; if so, determining reference historical synchronized data from the candidate historical synchronized data, and determining the current transmission data corresponding to the current synchronized data according to the reference historical synchronized data and the current synchronized data; wherein the current transmission data includes a reference data identifier of the reference historical synchronized data and differential associated data; sending the current transmission data to the server so that the server generates and stores the current synchronized data according to the current transmission data and the candidate historical synchronized data, and determines the current data identifier of the current synchronized data; receiving the current data identifier fed back by the server, and storing the current synchronized data and the current data identifier. In the above solution, the client sends the current transmission data including the reference data identifier and the differential associated data to the server, so that the server generates the current synchronized data according to the current transmission data and the stored candidate historical synchronized data, realizing that when there is candidate historical synchronized data in both the client and the server under the current data structure, the client does not need to send the repeated part of the data again, reducing the amount of data transmitted between the client and the server and improving the efficiency of data transmission.

[0065] On the basis of the above technical solution, after determining whether there is candidate historical synchronized data under the current data structure, the method further includes: if not, sending the current synchronized data to the server so that the server receives and stores the current synchronized data, and determines the current data identifier of the current synchronized data; receiving the current data identifier fed back by the server, and storing the current synchronized data and the current data identifier.

[0066] Specifically, if there is no candidate historical synchronized data under the current data structure in the client, it indicates that there is no same candidate historical synchronized data in the server either. At this time, the client needs to directly send the current synchronized data to the server; the server determines the current data identifier of the current synchronized data, and stores the current data identifier and the current synchronized data correspondingly; the server sends the current data identifier to the client; the client stores the current data identifier and the current synchronized data correspondingly.

[0067] It can be understood that if there is no candidate historical synchronized data under the current data structure of the client, the current synchronized data is directly sent to the server so that at least one synchronized data that can be used as a reference for subsequent operations is stored in the server, realizing the necessary transmission of synchronized data and improving the effectiveness of data transmission between the client and the server.

[0068] Embodiment 2

[0069] Figure 2It is a flowchart of a data transmission method provided in the second embodiment of the present invention. On the basis of the above embodiments, further, the operation of "determining the current transmission data corresponding to the current synchronization data according to the reference historical synchronization data and the current synchronization data" is refined into "determining the initial data difference position and the corresponding data difference state between the reference historical synchronization data and the current synchronization data; according to the data difference state, determining the initial data difference value of the corresponding initial data difference position, and generating difference association data including the initial data difference position and the initial data difference value; determining the reference data identifier of the reference historical synchronization data, and determining the current transmission data corresponding to the current synchronization data according to the reference data identifier, the difference association data, and the preset data separator", so as to improve the determination mechanism of the current transmission data. It should be noted that for parts not described in detail in the embodiments of the present invention, reference may be made to the descriptions of other embodiments.

[0070] See Figure 2 The data transmission method shown includes:

[0071] S210. Obtain the data to be synchronized, and update the data to be synchronized according to the preset sorting strategy to obtain the current synchronization data.

[0072] S220. Determine the current data structure of the current synchronization data, and determine whether there is candidate historical synchronization data under the current data structure.

[0073] S230. If it exists, determine the reference historical synchronization data from the candidate historical synchronization data, and determine the initial data difference position and the corresponding data difference state between the reference historical synchronization data and the current synchronization data.

[0074] Among them, the initial data difference position refers to the position of the data with differences in the reference historical synchronization data and the current synchronization data. Exemplarily, the initial data difference position can be the difference sequence number. For example, the data at the 52nd position in the current synchronization data is different from the reference historical synchronization data.

[0075] Among them, the data difference state can be understood as the situation where there are differences between the current synchronization data and the reference historical synchronization data. Exemplarily, the data difference state includes a data missing state, a data adding state, and a data replacing state.

[0076] Among them, the data missing state can characterize that at least part of the data is missing in the current synchronization data compared with the reference historical synchronization data. The data adding state can characterize that at least part of the data is added in the current synchronization data compared with the reference historical synchronization data. The data replacing state can characterize that the data at a certain initial data difference position in the current synchronization data is different from the data at the corresponding initial data difference position in the reference historical synchronization data.

[0077] It is understandable that the data difference state includes at least one of a data missing state, a data adding state, and a data replacing state, which improves the diversity and richness of the data difference state.

[0078] Specifically, if any, the client compares the candidate historical synchronization data with the current synchronization data respectively, and determines the candidate historical synchronization data with the smallest difference as the reference historical synchronization data from them; the client determines the initial data difference position between the reference historical synchronization data and the current synchronization data and the data difference state corresponding to the initial data difference position.

[0079] S240. Determine the initial data difference value corresponding to the corresponding initial data difference position according to the data difference state, and generate difference association data including the initial data difference position and the initial data difference value.

[0080] Wherein, the initial data difference value refers to the value at which the current synchronization data is different from the reference historical synchronization data at the initial difference data position.

[0081] In an optional embodiment, generating difference association data including the initial data difference position and the initial data difference value includes: determining whether there are consecutive initial data difference positions among the initial data difference positions where the data difference state is the data replacing state, and if so, merging the consecutive initial data difference positions to obtain candidate data difference positions; merging the initial data difference values corresponding to the candidate data difference positions to obtain candidate data difference values; determining the difference association data according to the candidate data difference positions, the candidate data difference values, the unmerged initial data difference positions, and the initial data difference values.

[0082] Wherein, the candidate data difference position refers to the data difference position obtained after merging at least two initial data difference positions. The candidate data difference value refers to the data difference value obtained after merging the initial data difference values corresponding to the candidate data difference positions.

[0083] Specifically, determine whether there are at least two adjacent initial data difference positions among the initial data difference positions where the data difference state is the data replacing state; if so, merge the adjacent initial data difference positions to obtain candidate data difference positions, that is, use the initial data difference position in front in the consecutive initial data difference positions as the candidate data difference position, and replace the consecutive initial data difference positions with the candidate data difference position; merge the initial data difference values corresponding to the candidate data difference positions to obtain the candidate data difference value corresponding to the candidate data difference position; generate difference association data including at least two of the candidate data difference positions, the candidate data difference values, the unmerged initial data difference positions, and the unmerged initial data difference values.

[0084] For example, if the initial data difference positions where the data difference status is the data replacement status include 52, 66, 67, and 98, the initial data difference value corresponding to the initial data difference position 52 is A, the initial data difference value corresponding to the initial data difference position 66 is B, the initial data difference value corresponding to the initial data difference position 67 is C, and the initial data difference value corresponding to the initial data difference position 98 is D, then it is determined that there are consecutive initial data difference positions, namely 66 and 67. The initial data difference positions 66 and 67 are merged to obtain the candidate data difference position 66; the initial data difference values B and C corresponding to the candidate data difference position are merged to obtain the candidate data difference value BC; generate the difference association data including the candidate data difference position 66, the candidate data difference value BC, the unmerged initial data difference positions 52 and 98, and the unmerged initial data difference values A and D.

[0085] It can be understood that by merging the consecutive initial data difference positions where the data difference status is the data replacement status, the candidate data difference positions are obtained, and then the initial data difference values corresponding to the candidate data difference positions are merged to obtain the candidate data difference values, which further reduces the amount of data in the difference association data, and further reduces the amount of the current transmission data generated subsequently.

[0086] It should be noted that if the data difference status is the data missing status, a preset data missing symbol is added before the initial data difference position; if the data difference status is the data addition status, a preset data addition symbol is added before the initial data difference position. The preset data missing symbol refers to a symbol that is preset and can be used to represent that there is data missing at a certain initial data difference position. The preset data addition symbol refers to a symbol that is preset and can be used to represent that there is data addition at a certain initial data difference position.

[0087] The embodiments of the present invention do not make any limitations on the setting of the preset data missing symbol and the preset data addition symbol, and they can be set by those skilled in the art according to experience or needs. Exemplarily, the preset data missing symbol can be represented by "-". If the initial data difference positions in the data missing status are consecutive, they are merged and presented in the format of "-start position number - end position number". The start position number refers to the initial data difference position that is the earliest among the consecutive initial data difference positions where the data difference status is the data missing status. The end position number refers to the initial data difference position that is the last among the consecutive initial data difference positions where the data difference status is the data missing status. Exemplarily, the preset data addition symbol can be represented by "+".

[0088] S250. Determine the reference data identifier of the reference historical synchronization data, and determine the current transmission data corresponding to the current synchronization data according to the reference data identifier, the difference correlation data, and the preset data separator.

[0089] Among them, the preset data separator refers to a symbol that is preset and can be used to isolate data. In the embodiments of the present invention, no limitation is imposed on the preset data separator, and it can be set by those skilled in the art according to experience or needs. Exemplarily, the preset data separator can be "|".

[0090] Exemplarily, the data format in the current transmission data can be the reference data identifier, the preset data separator, the difference correlation data, and the preset data separator. For example, the current transmission data can be 1|52,4|127,9|147,3|176,38; where 1 represents the reference data identifier of the reference historical synchronization data; 52, 127, and 147 represent the initial data difference positions; 176 represents the candidate data difference position; 4, 9, and 3 represent the initial data difference values corresponding to the corresponding initial data difference positions; 38 represents the candidate data difference value corresponding to the candidate data difference position.

[0091] S260. Send the current transmission data to the server, so that the server generates and stores the current synchronization data according to the current transmission data and the candidate historical synchronization data, and determines the current data identifier of the current synchronization data.

[0092] S270. Receive the current data identifier fed back by the server, and store the current synchronization data and the current data identifier.

[0093] The embodiments of the present invention provide a data transmission solution. By refining the operation of determining the current transmission data corresponding to the current synchronization data according to the reference historical synchronization data and the current synchronization data into determining the initial data difference positions and the corresponding data difference states between the reference historical synchronization data and the current synchronization data; according to the data difference states, determining the initial data difference values of the corresponding initial data difference positions, and generating difference correlation data including the initial data difference positions and the initial data difference values; determining the reference data identifier of the reference historical synchronization data, and determining the current transmission data corresponding to the current synchronization data according to the reference data identifier, the difference correlation data, and the preset data separator, the determination mechanism of the current transmission data is improved. In the above solution, by determining the initial data difference positions and the data difference states, then determining the initial data difference values according to the data difference states, generating difference correlation data including the initial data difference positions and the initial data difference values, and determining the current transmission data corresponding to the current synchronization data according to the reference data identifier, the difference correlation data, and the preset data separator, the accuracy of the determined current transmission data is improved.

[0095] Figure 3 The flowchart of a data transmission method provided in Embodiment 3 of the present invention is applicable to the data transmission scenario in the Internet of Things. This method can be executed by a data transmission device, which can be implemented in software and / or hardware and can be configured in an electronic device with data transmission function.

[0096] See Figure 3 The data transmission method shown is applied to the server side and includes:

[0097] S310. Receive the current transmission data sent by the client.

[0098] Among them, the current transmission data is the current synchronization data obtained by the client by updating the to-be-synchronized data acquired according to a preset sorting strategy, and is obtained by comparing with the reference historical synchronization data determined from the candidate historical synchronization data.

[0099] The current transmission data includes the reference data identifier of the reference historical synchronization data and the difference correlation data.

[0100] Among them, the current transmission data refers to the data sent by the client to the server. The to-be-synchronized data refers to the data that needs to be synchronously stored by the client and the server. The present invention embodiment does not make any limitation on the form of the to-be-synchronized data. Exemplarily, the to-be-synchronized data can be displayed in the form of characters, that is, the to-be-synchronized data can be a string. The current synchronization data refers to the data obtained after updating the to-be-synchronized data according to a preset sorting strategy.

[0101] Among them, the preset sorting strategy refers to a strategy that is preset and can be used to sort each sub-data in the to-be-synchronized data. Exemplarily, the preset sorting strategy can be a dictionary sorting strategy. Specifically, according to the dictionary sorting strategy, the keys in the to-be-synchronized data can be sorted to realize the update of the to-be-synchronized data and obtain the current synchronization data. It should be noted that the key-value pairs included in the current synchronization data and the to-be-synchronized data are the same. By the preset sorting strategy, the keys in the to-be-synchronized data are re-sorted to adjust the position of the key-value pairs in the to-be-synchronized data and obtain the current synchronization data.

[0102] Among them, the candidate historical synchronization data refers to the synchronization data that has been stored in the client and the server and belongs to the current data structure. The reference historical synchronization data refers to the candidate historical synchronization data with a smaller difference from the current synchronization data. Preferably, the reference historical synchronization data can be the candidate historical synchronization data with the smallest difference from the current synchronization data.

[0103] Among them, the reference data identifier can uniquely represent the identity of the reference historical synchronization data. The differential associated data refers to the associated data with differences between the current synchronization data and the reference historical synchronization data.

[0104] Specifically, the client obtains the data to be synchronized, sorts the keys in the data to be synchronized according to a preset sorting strategy to obtain the current synchronization data; the client determines the current data structure of the current synchronization data and determines whether there is candidate historical synchronization data under the current data structure, that is, determines whether the current synchronization data is the first synchronization data belonging to the current data structure; if there is candidate historical synchronization data under the current data structure, the client determines the reference historical synchronization data with the smallest difference from the current synchronization data among the candidate historical synchronization data; compares the reference historical synchronization data with the current synchronization data to determine the differential associated data; determines the current transmission data according to the reference data identifier of the reference historical synchronization data and the differential associated data; the client sends the current transmission data to the server; the server receives the current transmission data.

[0105] S320. Determine the reference historical synchronization data from the candidate historical synchronization data according to the reference data identifier, and generate the current synchronization data according to the differential associated data and the reference historical synchronization data.

[0106] Specifically, the server determines the reference historical synchronization data from the stored candidate historical synchronization data according to the current parameter data identifier; the server generates the current synchronization data according to the differential associated data and the reference historical synchronization data.

[0107] It should be noted that in the process of the server generating the current synchronization data according to the reference historical synchronization data and the differential associated data, the situation where the current synchronization data replaces the reference historical synchronization data will not occur, that is, the reference historical synchronization data is still retained, and a new current synchronization data is generated.

[0108] S330. Determine the current data identifier of the current synchronization data, and store the current synchronization data and the current data identifier.

[0109] Among them, the current data identifier can uniquely represent the identity of the current synchronization data.

[0110] Specifically, the server determines the current data identifier of the current synchronization data and stores the current synchronization data and the current data identifier correspondingly.

[0111] S340. Send the current data identifier to the client so that the client stores the current synchronization data and the current data identifier.

[0112] Specifically, the server sends the current data identifier to the client; the client receives the current data identifier fed back by the server; the client stores the current synchronized data and the current data identifier in a corresponding manner.

[0113] An embodiment of the present invention provides a data transmission solution. By receiving the current transmission data sent by the client, where the current transmission data is obtained by the client comparing the current synchronized data updated from the to-be-synchronized data obtained according to a preset sorting strategy with the reference historical synchronized data determined from the candidate historical synchronized data. The current transmission data includes the reference data identifier of the reference historical synchronized data and the difference correlation data.

[0115] On the basis of the above embodiments, an embodiment of the present invention provides an optional example of data transmission. It should be noted that for the parts not detailed in the embodiments of the present invention, reference can be made to the descriptions of other embodiments.

[0116] For example, if the real-time data (i.e., the data to be synchronized) transmitted by the environmental monitoring device (i.e., the client) to the server (i.e., the service provider) for the first time is {"deviceCode":"YS20230224020","externalNo":"JUCHENG","deviceTime":"1732258632000","noise":"25.8","pmTwoFive":"23.2","pmTen":"32.8","tsp":"47.4","temperature":"9.8","humidity":"55.0","windSpeed":"1.0","windAngle":"45.0"}; and the real-time data transmitted to the server for the second time 10 seconds later is {"deviceCode":"YS20230224020","externalNo":"JUCHENG","deviceTime":"1732258642000","noise":"25.8","pmTwoFive":"23.3","pmTen":"32.9","tsp":"38.4","temperature":"9.8","humidity":"55.0","windSpeed":"1.0","windAngle":"45.0"}; comparing the data to be synchronized for the two times, only the values of the following keys have changed, namely "deviceTime":"1732258632000","pmTwoFive":"23.2","pmTen":"32.8","tsp":"47.4"

[0117] "deviceTime":"1732258642000","pmTwoFive":"23.3","pmTen":"32.9","tsp":"38.4".

[0118] In the data transmission solution provided by the embodiments of the present invention, when the client first transmits real-time data to the server, all keys are sorted in alphabetical order first to obtain the following JSON (JavaScript Object Notation) string (i.e., the current synchronization data): {"deviceCode":"YS20230224020","deviceTime":"1732258632000","externalNo":"JUCHENG","humidity":"55.0","noise":"25.8","pmTen":"32.8","pmTwoFive":"23.2","temperature":"9.8","tsp":"47.4","windAngle":"45.0","windSpeed":"1.0"}; The client sends the above JSON string to the server, and after receiving it, the server saves the current transmitted data and the current data identifier 1 at the same time; The server returns a normal reception information signal and the current data identifier to the client. After receiving the signal, the client also saves the current data identifier 1 and the current synchronization data.

[0119] Further, when the client performs the second data transmission, all keys in the data to be synchronized this time are sorted in alphabetical order first to obtain the following JSON string: {"deviceCode":"YS20230224020","deviceTime":"1732258642000","externalNo":"JUCHENG","humidity":"55.0","noise":"25.8","pmTen":"32.9","pmTwoFive":"23.3","temperature":"9.8","tsp":"38.4","windAngle":"45.0","windSpeed":"1.0"}; By comparing the two JSON strings, the difference position number (i.e., the initial data difference position) and the difference value (the initial data difference value) are found, and the following Table 1 is obtained.

[0120] Table 1 Difference table between the current synchronization data and the reference historical synchronization data of the second data transmission

[0121]

[0122] Among them, the positions corresponding to serial numbers 4 and 5 in the initial data difference are consecutive positions and can be combined for processing. Assembled in the following format to obtain the current transmitted data. Reference data identifier|Difference position number 1, Initial data difference value|Difference position number 2, Initial data difference value|Difference position number n, Initial data difference value. Exemplarily, the current transmitted data corresponding to Table 1 can be 1|52,4|127,9|147,3|176,38. After the server receives the current transmitted data, it finds the corresponding reference historical synchronization data through the reference data identifier 1, and then obtains the complete data through the replacement method, that is, generates the current synchronization data.

[0123] It should be noted that when the initial data difference value includes "|" and / or ",", to avoid misinterpretation by the server, a preset escape character needs to be added in front of "|" and "," in the initial data difference value. Among them, the preset escape character can be pre-set and is used to represent a character with a special meaning in the current transmitted data. The embodiments of the present invention do not make any limitations on the setting of the preset escape character, and it can be set by those skilled in the art according to experience or needs. Exemplarily, the preset escape character can be "\".

[0124] Further, when the client sends data for the third time, first sort all the keys in the data to be synchronized this time in alphabetical order to obtain the current synchronization data {"deviceCode":"YS20230224020","deviceTime":"1732258652000","externalNo":"JUCHENG","humidity":"55.0","noise":"25","pmTen":"32.9","pmTwoFive":"23.3","temperature":"9.8","tsp":"38.4","windAngle":"45.0","windSpeed":"1","zsite":"101,35"}; determine the reference historical synchronization data from the candidate historical synchronization data under the current data structure; compare the current synchronization data with the reference historical synchronization data to find the difference position number and the difference value, and obtain Table 2 as follows.

[0125] Table 2 Difference table between the current synchronization data and the reference historical synchronization data for the third data transmission

[0126]

[0127] From the above table, we get 2|52,5|-112-113|215,"\,|+217,"zsite":"101\,35. Among them, 2 represents the reference data identifier for referring to historical synchronization data; 52, -112-113, 215, and +217 all represent the initial data difference positions; -112-113 represents the initial data difference position where data is missing; +217 represents the initial data difference position where data is added; 5, "\,, "zsite":"101\,35 represent the initial data difference values; \ represents the preset escape character. After the server receives the current transmitted data, it finds the corresponding reference historical synchronization data through the reference data identifier 2, and then obtains the complete data through the replacement method, that is, generates the current synchronization data.

[0128] The data transmission solution provided by the embodiments of the present invention can greatly reduce the amount of data transmitted and improve the data transmission efficiency; at the same time, the embodiments of the present invention have better effects on data with the same data structure and smaller data differences, especially in the scenario of a hardware data reporting server.
