[0002] Internet of Things (IOT) is to connect any object with network through various information sensors according to an agreed protocol, and the object carries out information interaction through information propagation medium to realize intelligent identification, positioning, tracking and supervision and other functions.

[0003] Due to the characteristics of low configuration and resource limitation of Internet of Things devices, the data type used is usually binary data, while the data type used by the Internet of Things platform is other data type, such as string data, for example, JSON format string data. The English full name of JSON is JavaScript Object Notation, and JSON is a data exchange format. This determines that after the Internet of Things platform receives the binary data sent by the Internet of Things device, the binary data needs to be first converted into string data, and then business processing is carried out.

[0054] The present application provides a method and device for processing data of Internet of Things, which realizes the conversion between binary data and string data according to uplink binary data templates, uplink string data templates, uplink metadata mapping templates, downlink binary data templates, downlink string data templates and downlink metadata mapping templates corresponding to the types of Internet of Things devices, so as to solve the problems of poor scalability, repeated development and high operation and maintenance cost of Internet of Things platform in the prior art.

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0056] Referring to Figure 1 , Figure 1 A flow chart of a method for processing data of Internet of Things disclosed by the present application. The method comprises:

[0057] Step S1: receiving original data sent by an Internet of Things device.

[0058] The original data sent by the Internet of Things device is binary data.

[0059] Here, the binary data and the string data are described.

[0060] Binary data is a sequence of one or more octets (or bytes). There are two differences between binary data and string data: first, binary data explicitly allows the storage of zero-valued bytes as well as other "unprintable" bytes (typically bytes outside the range 32 to 126). String data does not allow zero bytes, and does not allow any other byte values or sequences of byte values that are illegal for the selected character set encoding of the database. Second, operations on binary data deal with the actual bytes, while string data processing and retrieval depend on the locale. Simply put, binary data is suitable for storing data that is considered "raw bytes", while string data is suitable for storing text.

[0061] Step S2: Obtain the corresponding uplink binary data template, uplink string data template and uplink metadata mapping template according to the type of the Internet of Things device.

[0062] The uplink binary data template is used to describe the data structure of the raw data generated by the Internet of Things device. The uplink string data template is used to describe the data structure of the uplink string data corresponding to the Internet of Things device that can be recognized by the Internet of Things platform. The uplink metadata mapping template is used to describe the mapping relationship of the metadata in the uplink binary data template and the uplink string data template.

[0063] It should be noted that each type of Internet of Things device is pre-configured with a corresponding uplink binary data template, uplink string data template and uplink metadata mapping template. After receiving the raw data sent by the Internet of Things device, the corresponding uplink binary data template, uplink string data template and uplink metadata mapping template can be obtained according to the type of the Internet of Things device.

[0064] It should be noted that the type of the Internet of Things device includes the type of the Internet of Things device and the model of the Internet of Things device. That is, Internet of Things devices of different models are pre-configured with corresponding templates respectively.

[0065] The metadata in the string data will be described below with two examples.

[0066] Table 1 is the gas meter alarm information, and the binary content in the gas meter alarm information is the metadata.

[0067] Table 1

[0068]

[0069] Table 2 is satellite observation value information, and the binary content in the satellite observation value information is the metadata.

[0070] Table 2

[0071]

[0072] Here is a simple example to illustrate the function of the uplink metadata mapping template.

[0073] A string data of the IoT platform is as follows:

[0074] {

[0075] "gender":"male"

[0076] }

[0077] The description of "gender" in the string data is as follows: male represents male, and female represents female.

[0078] The binary data of the IoT device is as follows: 01001001

[0080] The description of the first bit of the above binary data is as follows: 0 represents male, and 1 represents female.

[0081] The uplink metadata mapping template contains the description information of the mapping relationship between "gender" in the string data and the first bit of the binary data. After the IoT platform receives the binary data sent by the IoT device, if the first bit of the binary data is "0", the IoT platform converts the first bit of the binary data into "gender.male"; if the first bit of the binary data is "1", the IoT platform converts the first bit of the binary data into "gender.female".

[0082] Step S3: Based on the uplink binary data template, the uplink string data template and the uplink metadata mapping template corresponding to the IoT device, the original data is converted to obtain the string data corresponding to the original data.

[0083] The uplink binary data template is used to describe the data structure of the original data generated by the IoT device, the uplink string data template is used to describe the data structure of the uplink string data corresponding to the IoT device which can be recognized by the IoT platform, and the uplink metadata mapping template can describe the mapping relationship between the metadata in the uplink binary data template and the uplink string data template. After the IoT platform receives the binary data sent by the IoT device, according to the uplink binary data template, the uplink string data template and the uplink metadata mapping template corresponding to the IoT device, the metadata in the binary data can be converted into the metadata in the string data, so as to complete the conversion of the binary data into the string data.

[0084] The present application Figure 1The shown Internet of Things data processing method, after the Internet of Things platform receives the binary data sent by the Internet of Things device, obtains the uplink binary data template, the uplink string data template and the uplink metadata mapping template corresponding to the Internet of Things device, the uplink metadata mapping template can describe the mapping relationship of the metadata in the uplink binary data template and the uplink string data template, and the Internet of Things platform can convert the binary data into string data based on the uplink binary data template, the uplink string data template and the uplink metadata mapping template. When a new Internet of Things device accesses the Internet of Things platform, only the corresponding uplink binary data template, uplink string data template and uplink metadata mapping template need to be configured for the newly accessed Internet of Things device, so that the binary data sent by the Internet of Things platform can be converted into string data, without the need for reprogramming customization development or re-interpretation script customization processing, which can effectively improve the scalability of the Internet of Things platform, reduce the repeated development workload, and reduce the operation and maintenance cost of the Internet of Things platform.

[0085] Referring to Figure 2 , Figure 2 is a flowchart of another Internet of Things data processing method disclosed in the present application. The method comprises:

[0086] Step S1: receiving the original data sent by the Internet of Things device.

[0087] Among them, the original data sent by the Internet of Things device is binary data.

[0088] Step S2: obtaining the corresponding uplink binary data template, uplink string data template and uplink metadata mapping template according to the type of the Internet of Things device.

[0089] Among them, the uplink binary data template is used to describe the data structure of the original data generated by the Internet of Things device. The uplink string data template is used to describe the data structure of the uplink string data corresponding to the Internet of Things device which can be recognized by the Internet of Things platform. The uplink metadata mapping template is used to describe the mapping relationship of the metadata in the uplink binary data template and the uplink string data template.

[0090] Step S3: converting the original data based on the uplink metadata mapping template to obtain the string data corresponding to the original data.

[0091] Step S4: obtaining the downlink string data to be sent to the target Internet of Things device.

[0092] Step S5: obtaining the corresponding downlink binary data template, downlink string data template and downlink metadata mapping template according to the type of the target Internet of Things device.

[0093] The downlink binary data template is used to describe a data structure of downlink binary data that can be recognized by the target IoT device. The downlink string data template is used to describe a data structure of downlink string data generated by the IoT platform and corresponding to the target IoT device. The downlink metadata mapping template is used to describe a mapping relationship of metadata in the downlink binary data template and the downlink string data template.

[0094] It should be noted that each type of IoT device is preconfigured with corresponding downlink binary data templates, downlink string data templates, and downlink metadata mapping templates. After obtaining the downlink string data to be sent to the target IoT device, the corresponding downlink binary data template, downlink string data template, and downlink metadata mapping template can be obtained according to the type of the target IoT device.

[0095] Here, the function of the downlink metadata mapping template is still described by using the example in the above.

[0096] A string data of the IoT platform is as follows:

[0097] {

[0098] "gender":"male"

[0099] }

[0100] The description of "gender" in the string data is as follows: male represents male, and female represents female.

[0101] The binary data of the IoT device is as follows: 01001001

[0103] The description of the first bit of the above binary data is as follows: 0 represents male, and 1 represents female.

[0104] The downlink metadata mapping template contains description information of a mapping relationship of "gender" in the string data and the first bit of the binary data. After the IoT platform generates the string data, if the string data contains "gender.male", the metadata is converted into the first bit "0" in the binary data; if the string data contains "gender.female", the metadata is converted into the first bit "1" in the binary data.

[0105] Step S6: converting the downlink string data based on the downlink binary data template, the downlink string data template, and the downlink metadata mapping template to obtain binary data corresponding to the downlink string data.

[0106] The downlink binary data template is used to describe a data structure of downlink binary data that can be identified by the target IoT device, the downlink string data template is used to describe a data structure of downlink string data generated by the IoT platform and corresponding to the target IoT device, and the downlink metadata mapping template can describe a mapping relationship of metadata in the downlink binary data template and the downlink string data template. After the IoT platform generates the string data to be sent, the metadata in the string data can be converted into metadata in binary data according to the downlink binary data template, the downlink string data template and the downlink metadata mapping template corresponding to the target IoT device, so as to complete the conversion of the string data into binary data.

[0107] Step S7: sending the binary data to the target IoT device.

[0108] The present application Figure 2 The IoT data processing method shown in the figure, after the IoT platform receives the binary data sent by the IoT device, obtains the uplink binary data template, the uplink string data template and the uplink metadata mapping template corresponding to the IoT device, the uplink metadata mapping template can describe the mapping relationship of metadata in the uplink binary data template and the uplink string data template, the IoT platform can convert the binary data into string data based on the uplink binary data template, the uplink string data template and the uplink metadata mapping template; after the IoT platform generates the string data to be sent to the target IoT device, obtains the downlink binary data template, the downlink string data template and the downlink metadata mapping template corresponding to the target IoT device, the downlink metadata mapping template can describe the mapping relationship of metadata in the downlink binary data template and the downlink string data template, and the IoT platform can convert the string data into binary data based on the downlink binary data template, the downlink string data template and the downlink metadata mapping template.

[0109] When a new IoT device accesses the IoT platform, only the corresponding uplink binary data template, uplink string data template, uplink metadata mapping template, downlink binary data template, downlink string data template and downlink metadata mapping template need to be configured for the newly accessed IoT device, so that the binary data sent by the IoT platform can be converted into string data, and the string data to be sent to the IoT device can be converted into binary data, without the need for re-programming customization development or re-interpretation script customization processing, which can effectively improve the scalability of the IoT platform, reduce the workload of repeated development, and reduce the operation and maintenance cost of the IoT platform.

[0110] It should be noted that the present application Figure 1 and Figure 2The illustrated Internet of Things data processing method can be executed by a metadata analysis engine in the Internet of Things platform.

[0113] It should be noted that in the process of initializing the Internet of Things platform, the uplink template set and the downlink template set corresponding to the Internet of Things device need to be constructed. For multiple types of Internet of Things devices accessing the Internet of Things platform, the uplink template set and the downlink template set corresponding to each type of Internet of Things device need to be constructed respectively. In addition, when a new Internet of Things device accesses the Internet of Things platform, the uplink template set and the downlink template set corresponding to the newly accessed Internet of Things device need to be constructed.
