[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0041] Embodiment 1

[0042] Figure 1 This is a flowchart of a data transmission method provided in Example 1 of the present invention. This embodiment is applicable to data transmission situations in the Internet of Things. The 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 that carries the data transmission function.

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

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

[0045] The data to be synchronized refers to the data that the client and the server need to synchronize and store. The embodiment of the present invention does not limit the form of the data to be synchronized. For example, 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 pre-set strategy that can be used to sort the sub-data in the data to be synchronized. Exemplarily, the preset sorting strategy can be a dictionary sorting strategy. Specifically, the keys in the data to be synchronized can be sorted according to the dictionary sorting strategy to achieve the update of the data to be synchronized and obtain the current synchronized data. It should be noted that the key-value pairs contained in the current synchronized data and the data to be synchronized are the same. Through the preset sorting strategy, the keys in the data to be synchronized are reordered, and the positions of the key-value pairs in the data to be synchronized are adjusted to obtain the current synchronized data.

[0047] The current synchronization data refers to data obtained after the data to be synchronized is updated according to a preset sorting strategy.

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

[0049] S120: Determine the current data structure of the current synchronization data, and judge whether there is candidate historical synchronization data under the current data structure.

[0050] The current data structure refers to the data structure of the current synchronization 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 a data structure pre-stored in the client.

[0051] 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.

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

[0053] S130: If so, determine the reference historical synchronization data from the candidate historical synchronization data, and determine the current transmission data corresponding to the current synchronization data according to the reference historical synchronization data and the current synchronization data.

[0054] The currently transmitted data includes a reference data identifier that refers to the historical synchronization data, and difference-related data.

[0055] The reference historical synchronization data refers to candidate historical synchronization data with a smaller difference from the current synchronization data. Preferably, the reference historical synchronization data may be candidate historical synchronization data with a smallest difference from the current synchronization data.

[0056] Exemplarily, the data similarity between each candidate historical synchronization data and the current synchronization data is determined, and the reference historical synchronization data is determined from the candidate historical synchronization data according to the data similarity. The data similarity can be used to quantify the similarity between the candidate historical synchronization data and the current synchronization data.

[0057] 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 synchronization data. The difference-related data refers to the related data that differs between the current synchronization data and the reference historical synchronization data.

[0058] Specifically, if there are candidate historical synchronization data under the current data structure, the client determines the reference historical synchronization data with the smallest difference between the candidate historical synchronization data and the current 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 and the difference-related data of the reference historical synchronization data.

[0059] S140: 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.

[0060] 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 scheme, which obtains the data to be synchronized and updates the data to be synchronized according to a preset sorting strategy to obtain the current synchronization data; determines the current data structure of the current synchronization data, and judges whether there is candidate historical synchronization data under the current data structure; if so, determines the reference historical synchronization data from the candidate historical synchronization data, and determines the current transmission data corresponding to the current synchronization data based on the reference historical synchronization data and the current synchronization data; wherein the current transmission data includes a reference data identifier of the reference historical synchronization data, and difference-related data; sends the current transmission data to a 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; receives the current data identifier fed back by the server, and stores the current synchronization data and the current data identifier. In the above scheme, the client sends the current transmission data including the reference data identifier and the difference-related data to the server, so that the server generates the current synchronization data based on the current transmission data and the stored candidate historical synchronization data. This ensures that under the current data structure, if the candidate historical synchronization data already exists in the client and the server, the client does not need to send the repeated data again, thereby 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 synchronization data under the current data structure, the method also includes: if not, sending the current synchronization data to the server, so that the server receives and stores the current synchronization data, and determines the current data identifier of the current synchronization data; receiving the current data identifier fed back by the server, and storing the current synchronization data and the current data identifier.

[0066] Specifically, if there is no candidate historical synchronization data under the current data structure in the client, it means that the same candidate historical synchronization data does not exist in the server. At this time, the client needs to send the current synchronization data directly to the server; the server determines the current data identifier of the current synchronization data, and stores the current data identifier and the current synchronization data correspondingly; the server sends the current data identifier to the client; the client stores the current data identifier and the current synchronization data correspondingly.

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

[0068] Embodiment 2

[0069] Figure 2It is a flow chart of a data transmission method provided in the second embodiment of the present invention. Based on the above embodiments, this embodiment further refines the operation of "determining the current transmission data corresponding to the current synchronization data based on the reference historical synchronization data and the current synchronization data" into "determining the initial data difference position and the corresponding data difference state between the reference historical synchronization data and the current synchronization data; determining the initial data difference value of the corresponding initial data difference position based on the data difference state, and generating difference-related 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 based on the reference data identifier, the difference-related data and the preset data separator" to improve the determination mechanism of the current transmission data. It should be noted that for the parts not described in detail in the embodiments of the present invention, reference can be made to the descriptions of other embodiments.

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

[0071] S210: Acquire the data to be synchronized, and update the data to be synchronized according to a preset sorting strategy to obtain current synchronized 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 so, 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] The initial data difference position refers to the position of data that differs between the reference historical synchronization data and the current synchronization data. Exemplarily, the initial data difference position may be a difference position number, such as the data at position 52 in the current synchronization data differs from the reference historical synchronization data.

[0075] The data difference state can be understood as a situation where there is a difference between the current synchronization data and the reference historical synchronization data. Exemplarily, the data difference state includes a data missing state, a data added state, and a data replaced state.

[0076] The data missing state may indicate that the current synchronization data is missing at least some data compared to the reference historical synchronization data. The data added state may indicate that the current synchronization data is increased at least some data compared to the reference historical synchronization data. The data replacement state may indicate 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 can be understood that the data difference state includes at least one of a data missing state, a data added state and a data replaced state, which improves the diversity and richness of the data difference state.

[0078] Specifically, if it exists, 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; the client determines the initial data difference position where there is a difference 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 an initial data difference value corresponding to the initial data difference position according to the data difference state, and generate difference-associated data including the initial data difference position and the initial data difference value.

[0080] The initial data difference value refers to the difference in value between the current synchronization data and the reference historical synchronization data at the initial difference data position.

[0081] In an optional embodiment, generating difference-associated data including initial data difference positions and initial data difference values ​​includes: determining whether there are continuous initial data difference positions among the initial data difference positions whose data difference state is a data replacement state, and if so, merging the continuous 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; and determining the difference-associated data based on the candidate data difference positions, the candidate data difference values, the unmerged initial data difference positions, and the initial data difference values.

[0082] The candidate data difference position refers to a data difference position obtained by merging at least two initial data difference positions, and the candidate data difference value refers to a data difference value obtained by merging initial data difference values ​​corresponding to the candidate data difference position.

[0083] Specifically, determine whether there are at least two adjacent initial data difference positions in the initial data difference positions whose data difference state is the data replacement state; if so, merge the adjacent initial data difference positions to obtain a candidate data difference position, that is, use the previous initial data difference position in the continuous initial data difference positions as the candidate data difference position, and replace the continuous 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 values ​​corresponding to the candidate data difference positions; and generate difference-related 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 whose data difference state is the data replacement state 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 continuous initial data difference positions, namely 66 and 67, and 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; and 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 are generated to generate difference-associated data.

[0085] It can be understood that by setting the data difference state to a data replacement state and merging consecutive initial data difference positions to obtain candidate data difference positions, and then merging the initial data difference values ​​corresponding to the candidate data difference positions to obtain candidate data difference values, the amount of data in the difference-associated data is further reduced, thereby reducing the amount of data of the current transmission data generated subsequently.

[0086] It should be noted that if the data difference state is a data missing state, a preset data missing symbol is added before the initial data difference position; if the data difference state is a data added state, a preset data added symbol is added before the initial data difference position. The preset data missing symbol refers to a pre-set symbol that can be used to indicate that there is data missing at a certain initial data difference position. The preset data added symbol refers to a pre-set symbol that can be used to indicate that there is data added at a certain initial data difference position.

[0087] The embodiment of the present invention does not impose any limitation on the setting of the preset data missing symbol and the preset data addition symbol, which can be set by the technician according to experience or needs. Exemplarily, the preset data missing symbol can be represented by "-". If the initial data difference positions of the data missing state are continuous, they are merged and the format of "-starting position number-ending position number" is used. Among them, the starting position number refers to the data difference state is the data missing state, and the initial data difference position that ranks first in the continuous initial data difference positions. The ending position number refers to the data difference state is the data missing state, and the initial data difference position that ranks last in the continuous initial data difference positions. Exemplarily, the preset data addition symbol can be represented by "+".

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

[0089] The preset data separator is a pre-set symbol that can be used to separate data. The embodiment of the present invention does not limit the preset data separator, which can be set by technicians based on experience or needs. Exemplarily, the preset data separator can be "|".

[0090] Exemplarily, the data format in the current transmission data may be a reference data identifier, a preset data separator, difference-related data, and a preset data separator. For example, the current transmission data may be 1|52,4|127,9|147,3|176,38; wherein 1 represents the reference data identifier of the reference historical synchronization data; 52, 127, and 147 represent the initial data difference position; 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; and 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 embodiment of the present invention provides a data transmission scheme, which refines 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 position and the corresponding data difference state between the reference historical synchronization data and the current synchronization data; determining the initial data difference value of the corresponding initial data difference position according to the data difference state, 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, thereby improving the determination mechanism of the current transmission data. The above scheme improves the accuracy of the determined current transmission data by determining the initial data difference position and the data difference state, and then determining the initial data difference value according to the data difference state, generating difference association data including the initial data difference position and the initial data difference value, 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.

[0095] Figure 3 This is a flowchart of a data transmission method provided in Embodiment 3 of the present invention. This embodiment is applicable to data transmission situations in the Internet of Things. The 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 that carries the data transmission function.

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

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

[0098] The currently transmitted data is the current synchronization data obtained by the client updating the acquired data to be synchronized according to a preset sorting strategy and comparing it with the reference historical synchronization data determined from the candidate historical synchronization data.

[0099] The currently transmitted data includes reference data identifiers of reference historical synchronization data and difference-related data.

[0100] Among them, the currently transmitted data refers to the data sent by the client to the server. The data to be synchronized refers to the data that the client and the server need to synchronize and store. The embodiment of the present invention does not impose any limitation on the form of the data to be synchronized. For example, the data to be synchronized can be displayed in the form of characters, that is, the data to be synchronized can be a string. The currently synchronized data refers to the data obtained after the data to be synchronized is updated according to the preset sorting strategy.

[0101] Among them, the preset sorting strategy refers to a pre-set strategy that can be used to sort the sub-data in the data to be synchronized. Exemplarily, the preset sorting strategy can be a dictionary sorting strategy. Specifically, the keys in the data to be synchronized can be sorted according to the dictionary sorting strategy to achieve the update of the data to be synchronized and obtain the current synchronized data. It should be noted that the key-value pairs contained in the current synchronized data and the data to be synchronized are the same. Through the preset sorting strategy, the keys in the data to be synchronized are reordered, and the positions of the key-value pairs in the data to be synchronized are adjusted to obtain the current synchronized data.

[0102] 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 that has a smaller difference with the current synchronization data. Preferably, the reference historical synchronization data can be the candidate historical synchronization data that has the smallest difference with the current synchronization data.

[0103] The reference data identifier can uniquely represent the identity of the reference historical synchronization data. The difference-related data refers to the related data that has differences between the current synchronization data and the reference historical synchronization data.

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

[0105] S320: Determine reference historical synchronization data from candidate historical synchronization data according to the reference data identifier, and generate current synchronization data according to the difference-related 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; and generates the current synchronization data according to the difference association data and the reference historical synchronization data.

[0107] It should be noted that when the server generates current synchronization data based on reference historical synchronization data and difference-related data, the current synchronization data will not replace the reference historical synchronization data, 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] 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 in correspondence with each other.

[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; and the client stores the current synchronization data and the current data identifier in correspondence.

[0113] The embodiment of the present invention provides a data transmission scheme, which receives the current transmission data sent by the client; wherein the current transmission data is the current synchronization data obtained by the client updating the acquired data to be synchronized according to the preset sorting strategy, and the reference historical synchronization data determined from the candidate historical synchronization data; the current transmission data includes the reference data identifier of the reference historical synchronization data, and the difference associated data; according to the reference data identifier, the reference historical synchronization data is determined from the candidate historical synchronization data, and the current synchronization data is generated according to the difference associated data and the reference historical synchronization data; the current data identifier of the current synchronization data is determined, and the current synchronization data and the current data identifier are stored; the current data identifier is sent to the client so that the client stores the current synchronization data and the current data identifier.

[0114] Embodiment 4

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

[0116] For example, if the real-time data (i.e. data to be synchronized) transmitted by the environmental monitoring device (i.e. client) to the server (i.e. service end) 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"}; 10 seconds later, the real-time data transmitted to the server for the second 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"}. 0224020","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 two to-be-synchronized data, only the following key values ​​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 scheme provided by the embodiment of the present invention, when the client transmits real-time data to the server for the first time, all keys are first sorted according to the dictionary to obtain the following json (JavaScript Object Notation, JS object notation) string (i.e., 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 the server saves the current transmission data and the current data identifier 1 at the same time after receiving it; the server returns a normal reception information signal and the current data identifier to the client, and the client also saves the current data identifier 1 and the current synchronization data after receiving the signal.

[0119] Furthermore, when the client sends data for the second time, all keys in the data to be synchronized are sorted by dictionary 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"}; Compare the two JSON strings to find the difference position number (that is, the initial data difference position) and the difference value (initial data difference value), and obtain the following Table 1.

[0120] Table 1 Differences between the current synchronization data and the reference historical synchronization data for the second data transmission

[0121] Among them, the initial data difference positions corresponding to sequence numbers 4 and 5 are continuous positions and can be merged for processing. The current transmission data is assembled through the following format. 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 transmission data corresponding to Table 1 can be 1|52,4|127,9|147,3|176,38. After receiving the current transmission data, the server 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.

[0122] It should be noted that if the initial data difference value includes "|" and / or ",", in order to avoid misunderstanding on the server side, it is necessary to add a preset escape character before the "|" and "," in the initial data difference value. Among them, the preset escape character can be pre-set and used to represent a character with a special meaning in the current transmission data. The embodiment of the present invention does not impose any limitation on the setting of the preset escape character, which can be set by the technician according to experience or needs. Exemplarily, the preset escape character can be "\".

[0123] Furthermore, when the client sends data for the third time, all keys in the data to be synchronized are sorted dictionary-wise 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"}; the reference historical synchronization data is determined from the candidate historical synchronization data under the current data structure; the current synchronization data is compared with the reference historical synchronization data to find the difference position number and difference value, and the following Table 2 is obtained.

[0124] Table 2 Differences between the current synchronization data and the reference historical synchronization data for the third data transmission

[0125] Through the above table, we get 2|52,5|-112-113|215,"\,|+217,"zsite":"101\,35. Among them, 2 represents the reference data identifier of the reference historical synchronization data; 52, -112-113, 215 and +217 all represent the initial data difference position; -112-113 represents the initial data difference position with missing data; +217 represents the initial data difference position with added data; 5, "\,", "zsite":"101\,35 represent the initial data difference value; \ represents the preset escape character. After receiving the current transmission data, the server 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.

[0126] The data transmission solution provided by the embodiment of the present invention can greatly reduce the amount of data transmitted and improve data transmission efficiency. At the same time, the embodiment of the present invention has better effects on data with the same data structure and smaller data differences, especially in the scenario of hardware data reporting server.
