Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Two data processing methods in an internet of things platform are provided in the related art, one method is that an internet of things equipment end converts acquired original equipment data into equipment data with a uniform format and uploads the equipment data to the internet of things platform, so that the internet of things platform can process and analyze the equipment data with the uniform format; the other method is that the internet of things equipment directly uploads the collected original equipment data to the internet of things platform, and due to the fact that different data transmission protocols used by different internet of things equipment, data formats of the original equipment data received by the internet of things platform are different, and the internet of things platform needs to process and analyze the equipment data in different data formats.
By adopting the method in the technology, on one hand, if the acquired original equipment data is converted into equipment data with a uniform format by the internet of things equipment for processing and analysis by the internet of things platform, the internet of things equipment is required to have higher data processing capacity, and some internet of things equipment does not have data processing capacity, such as a sensor; on the other hand, if format conversion is not needed to be performed on original equipment data, the internet of things platform directly processes and analyzes the equipment data in different formats, the internet of things platform needs to provide corresponding logical operation for relevant processing aiming at the equipment data in each data format, and when the types of data transmission protocols used by the internet of things equipment are more, the complexity of the logical operation of the internet of things platform can be increased, so that the data processing efficiency of the internet of things platform is reduced.
In order to solve the above problem, an embodiment of the present application provides a data processing method in an internet of things platform. Referring to fig. 1, a schematic diagram of an implementation environment provided by an exemplary embodiment of the present application is shown. The implementation environment includes an internet of things device 101 and an internet of things platform 102.
The internet of things device 101 is an information acquisition device in an internet of things system, and is mainly responsible for acquiring data, and is generally provided with a sensor (such as a photovoltaic sensor, a speed sensor, a pressure sensor and the like), wherein the sensor can convert information acquired by the device into an electric signal or output information in other required forms according to a certain rule, and besides data acquisition and transmission, the internet of things device also needs to have data processing and storage functions, and is generally applied to the fields of industry, power grids, smart homes, intelligent transportation and the like. In this embodiment of the application, the internet of things device 101 may send the acquired raw device data to the internet of things platform 102, and optionally, the internet of things device 101 may also receive an instruction issued by the internet of things platform.
The internet of things device 101 may communicate with the internet of things platform 102 through a gateway device (not shown).
The internet of things platform 102 is a cloud device in the internet of things system, and is configured to receive device data sent by the internet of things device 101, and store, process, and analyze the device data, so as to perform service discovery, provide a service query function, and implement an application service logic of the internet of things. In the embodiment of the present application, the physical network platform 102 may be divided into a connection center 103, a script engine 104, and a processing center 105 according to functions; the connection center 103 is used for establishing connection between the internet of things device 101 and the internet of things platform 102; the script engine 104 is configured to execute a corresponding script, and parse original device data uploaded by the internet of things device 101 to implement data format conversion, or perform data format conversion on data issued by the processing center; the processing center 105 may process and analyze the device data in the uniform data format that is obtained after the script is parsed.
In a possible implementation manner, after the internet of things device 101 is online and establishes a connection with the internet of things platform 102 through the connection center 103, the acquired raw device data is sent to the internet of things platform 102, and after the internet of things platform 102 receives the raw device data, the raw device data is firstly analyzed in the script engine 104 according to the target script to generate target device data in a uniform data format, and then the target device data in the uniform data format is sent to the processing center 105 for analysis processing.
By adopting the data processing method in the Internet of things platform provided by the embodiment of the application, data format conversion is not required to be carried out at the Internet of things equipment end, the logical operation of the Internet of things equipment end is reduced, and more Internet of things equipment without data processing capacity can be conveniently accessed to the Internet of things platform; before data processing analysis is carried out in a processing center of the Internet of things platform, a corresponding script is executed through a script engine, the data format of original equipment data is converted into uniform format data, the data of different formats can be prevented from being processed by an Internet of things platform end, logical operation of the Internet of things platform end is reduced, and therefore data processing efficiency of the Internet of things platform is improved.
Referring to fig. 2, a flowchart of a data processing method in an internet of things platform according to an exemplary embodiment of the present application is shown. In this embodiment, the method is described as an example of using the method for an internet of things platform shown in fig. 1, and the method includes the following steps.
For example, if the data transmission protocol used by the target internet of things device is a Message Queue Telemetry Transport (MQTT) protocol, the raw device data sent by the target internet of things device may be "0 x0100000014010004000025f502000a6162636465666768696a0300083ff23d70a3d70a3d0400140000000100000003000000050000000700000009050005000001a 703".
In one possible implementation, the target internet of things device uploads raw device data to the internet of things platform by using the MQTT protocol, that is, the internet of things platform receives the raw device data, and the raw device data adopts a first data format, that is, hexadecimal data.
Optionally, the target internet of things device may also use other data transmission protocols, for example, a restricted Application Protocol (CoAP), and the like.
The target script is stored in the Internet of things platform in advance by a device developer of the target Internet of things device and is associated with the target Internet of things device. For example, the internet of things platform includes a script database storing target scripts, and at least one script is stored in the script database.
In a possible implementation manner, after the internet of things platform receives the device data sent by the target internet of things device, the target script associated with the target internet of things device is found from the script database through the device identifier of the target internet of things device.
And 203, analyzing the original equipment data through the target script to generate target equipment data, wherein the target equipment data adopts a second data format, and the second data format is a predefined uniform data format.
The second data format is predefined by the platform manufacturer of the internet of things, namely, the data processed and analyzed by the processing center of the platform of the internet of things all adopt the second data format. For example, the second data format may be a JSON Object Notation (JSON) format or an extensible markup Language (XML) format, and the embodiment does not limit the type of the second data format.
In a possible implementation manner, after receiving original device data sent by a target internet of things device, the internet of things platform calls a target script associated with the original device data, and by running the target script, the original device data is converted into target device data in a second data format.
Illustratively, the target device data for converting the original device data in step 201 into JSON format may be: "
Alternatively, the target script may be run in a corresponding script engine.
And step 204, processing the target device data.
In a possible implementation manner, after the script engine runs the target script, analyzes the original device data, and generates the target device data, the target device data in the second data format is sent to a processing center in the target internet of things platform, and the processing center processes the target device data. The processing mode can be to store the target device data in a database for subsequent query; or analyzing the target device data to discover a certain business rule, and the like, and the processing method of the target device data is not limited in this embodiment.
To sum up, in the embodiment of the application, after the internet of things platform receives original device data sent by a target internet of things device, the original device data is analyzed by obtaining a target script corresponding to the target internet of things device, target device data in a uniform data format is generated, and then the target device data is processed by a processing center. The data format conversion of the Internet of things equipment is not needed, so that the logical operation of the Internet of things equipment can be reduced, and more Internet of things equipment without data processing capacity can be accessed to the Internet of things platform; before data processing analysis is carried out in a processing center of the Internet of things platform, the data format of original equipment data is converted into uniform format data through the target script, the phenomenon that the Internet of things platform processes the equipment data in different formats can be avoided, logical operation of an Internet of things platform end is reduced, and therefore data processing efficiency of the Internet of things platform is improved.
Because a certain compiling process is required for compiling the target script, and before the device developer uploads the target script to the internet of things platform, whether the target script can realize the data format conversion function, that is, whether the target script can convert the first data format into the second data format or convert the second data format into the first data format, and the like, is executed, the internet of things platform provides a simulation environment for compiling and testing the script for the device developer in a possible implementation manner.
Referring to fig. 3, a flowchart of a data processing method in an internet of things platform according to another exemplary embodiment of the present application is shown. In this embodiment, the method is described as an example of using the method for an internet of things platform shown in fig. 1, and the method includes the following steps.
In a possible implementation manner, when a target internet of things device needs to access an internet of things platform, device registration, script writing, testing and the like are firstly performed on a front-end interface of the internet of things platform.
Because the Internet of things platform uses a uniform data format when processing data, an Internet of things platform manufacturer can define a script writing specification, a device developer of the Internet of things device writes detailed logic codes for realizing data format conversion according to the script writing specification, the written target script is uploaded to the Internet of things platform, and the uniform script database stores and manages the target script so that the target script can be acquired when the original device data is uploaded by the subsequent target Internet of things device.
Illustratively, if the unified data format defined by the internet of things platform is a JSON format, the script writing specification may be:
in one possible implementation mode, a data analysis interface is provided in a front-end interface of the internet of things platform, so that a device developer of a target internet of things device writes and tests scripts in the data analysis interface.
Illustratively, as shown in fig. 4, a device developer of a target internet of things device may write and test a script in a data parsing interface 401, where the device developer may input the test script in an editing script window 402 and input test data in an analog input window 403, and accordingly, the internet of things platform obtains the test script and the test data.
And step 302, analyzing the test data through the test script to generate a test result.
In a possible implementation manner, after the device developer inputs the test script and the test data, the device developer selects to run the test script, and the internet of things platform parses the test data according to the test script to generate a test result, and feeds the test result back to the device developer, so that the device developer can determine whether the test script can realize data format conversion.
Illustratively, as shown in fig. 4, after the device developer inputs the test script and the test data, the operation control 407 may be clicked, and the platform of the internet of things may analyze the test data according to the test script, generate a test result, and display the test result in the operation result window 404.
Optionally, the device developer may also click the save draft control 406, and may temporarily save the test script, so that the subsequent device developer may continue to write the test script on the basis of the last writing.
Because the communication between the internet of things device and the internet of things platform is divided into two directions, namely, the device data uploaded by the internet of things device and the data issued by the internet of things platform, the test script also comprises two directions (two interfaces), the first interface converts the first data format into the second data format, and the second interface converts the second data format into the first data format.
In one possible implementation, as shown in fig. 5, step 302 may include:
In a possible implementation manner, the equipment developer selects a test type (simulation type) as the equipment uploading data, that is, selects the internet of things equipment to send the original equipment data to the internet of things platform, and at this time, the test data input by the equipment developer is in a first data format, and the test data is analyzed by calling a first interface of the test script to obtain a first test result.
Illustratively, as shown in fig. 4, when an equipment developer pulls down a simulation type control 405, selects equipment to send data, inputs test data in a first data format in a simulation input window 403, and clicks an operation control 407, the platform of the internet of things calls a first interface of a test script to analyze the test data, and if the test script is correct, the test data in a second data format is displayed in an operation result window 404.
In a possible implementation manner, the equipment developer selects a test type (simulation type) to issue data to the internet of things platform, that is, selects the internet of things platform to send data to the internet of things equipment, and at this time, the test data input by the equipment developer is in a second data format, and the test data is analyzed by calling a second interface of the test script to obtain a second test result.
Schematically, as shown in fig. 4, when the device developer pulls down the simulation type control 405, selects the internet of things platform to issue data, inputs test data in the second data format in the simulation input window 403, and clicks the operation control 407, the internet of things platform calls the second interface of the test script to analyze the test data, and if the test script is correct, the test data in the first data format is displayed in the operation result window 404.
And 303, if the test result indicates that the test script is correct and a script uploading instruction is received, storing the test script as a target script in a script database.
In a possible implementation manner, when the test result indicates that the test script is correct, the device developer may submit the test script, that is, the internet of things platform receives the script upload instruction, and may store the test script as a target script in the script database.
Illustratively, as shown in fig. 4, when the device developer determines that the test script is correct, the device developer may click the submission control 408, and accordingly, the internet of things platform receives a script upload instruction, and may store the test script as a target script in the script database.
The test script is stored in the script database as the target script, so that when the original device data is uploaded by the subsequent target internet of things device, the internet of things platform can call the target script to analyze the original device data, and therefore, the test script and the corresponding target internet of things device are stored in an associated manner.
Optionally, when the test result indicates that the test script has an error, error information, such as a parameter error (param error), a script service internal error (internal error), a script execution failure (script execution failed), a script execution timeout (script execution time), may be displayed in the operation result window, so that the device developer may modify the test script correspondingly.
Step 201 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
For the internet of things equipment using the same data transmission protocol, the uploaded original equipment data can be analyzed according to the same target script, and in order to avoid the occurrence of repeated target scripts, an equipment developer can establish a target equipment group to manage the internet of things equipment.
In a possible implementation manner, a device developer may register a target device group in a front-end interface of the internet of things platform, the target device group may include a plurality of internet of things devices, the internet of things devices in the target device group all use the same data transmission protocol, and correspondingly, analysis scripts (target scripts) used by the same target device group are the same.
Optionally, the device developer may associate the target device group with the target script while registering, and the association may be performed by associating the ID of the target device group with the target script.
In a possible implementation manner, when the internet of things platform receives original device data sent by a target internet of things device, a device ID of the target internet of things device may be obtained, and a target device group to which the target internet of things device belongs is determined according to the device ID, that is, a device group ID of the target device group is obtained.
In one possible implementation, after the internet of things platform obtains the device group ID of the target device group, the target script associated with the device group ID may be searched from the script database.
And 307, determining a target script engine corresponding to the target internet of things device according to the script language of the target script, wherein at least one script engine is arranged in the internet of things platform, and different script engines correspond to different script languages.
Because the script can be executed to implement the corresponding function after being translated by the script engine, and one script engine can only parse the script written using the same script language, in a possible implementation manner, the platform manufacturer of the internet of things can set at least one script engine in the platform of the internet of things so as to run the corresponding script.
Because different device developers use different scripting languages for writing the target script, in order to more accurately determine the target script engine to run the target script, optionally, when registering the target device group, the device developers may associate the target device group with the target script engine, so that the uploaded data corresponding to the target device group can be analyzed in the target script engine.
In a possible implementation manner, when the internet of things platform acquires a device group ID of a target device group, a corresponding target script engine is determined according to the device group ID.
Illustratively, as shown in fig. 6, if the internet of things device 601 adopts an MQTT protocol, a device developer writes a script using a java script (JavaScript) language, and after the internet of things device 601 establishes a connection with the connection center 603, original device data is sent to the internet of things platform 602, it is determined that a target script corresponding to a target device group to which the internet of things device 601 belongs is a JavaScript script 605, and a corresponding target script engine is a JavaScript script engine 604.
And 308, executing the target script through the target script engine, analyzing the original equipment data, and generating target equipment data, wherein the target equipment data adopts a second data format, and the second data format is a predefined uniform data format.
In one possible implementation, after the target script engine and the target script are determined, the target script engine may translate the target script into corresponding executable program instructions, parse raw device data according to the executable program instructions, and convert the raw device data into target device data in a second data format.
Illustratively, as shown in fig. 6, the JavaScript target script engine 604 executes the JavaScript script 605, parses the raw device data, converts the data format of the raw device data into a uniform data format, i.e., a second data format, and sends the uniform data format to the processing center 606.
Illustratively, as shown in FIG. 5, step 308 may include step 308A.
308A, calling a first interface of the target script through the target script engine, analyzing the original equipment data, and generating target equipment data, wherein the first interface indicates to convert the first data format into a second data format.
The target script comprises two directions, and the target internet of things equipment sends the original equipment data to the internet of things platform, wherein the original equipment data adopts a first data format, so that the first data format is correspondingly converted into a second data format, namely a first interface of the target script.
In a possible implementation manner, when the target script engine executes the target script, a first interface of the target script is called, the original device data is analyzed, and the target device data in the second data format is generated.
The implementation manner of this step may refer to step 204, which is not described herein.
In the embodiment of the application, through a front-end interface provided by an internet of things platform, a device developer of target internet of things equipment can write and test scripts in the front-end interface in advance so as to determine whether the test scripts can realize a corresponding data format conversion function, and when a test result indicates that the test scripts are correct, the test scripts can be submitted and stored into a script database so that subsequent target internet of things equipment can upload original device data or the internet of things platform can call when sending data to the target internet of things equipment; in addition, the target script is divided into a first interface and a second interface according to the data transmission direction, so that the first interface is called when the target internet of things device sends original device data, and the first data format is converted into the second data format.
In a possible application scenario, when the internet of things platform issues data to the internet of things device, the issued data generated by the internet of things platform all adopt the second data format, but the internet of things device cannot directly utilize the issued data, so that in a possible implementation manner, the second data format can be converted into the first data format by calling the second interface of the target script, and then the first data format is sent to the internet of things device.
Illustratively, the process of sending data to the internet of things device by the internet of things platform may include the following steps.
Generating issuing data, wherein the issuing data adopt a second data format, and the issuing data are at least used for indicating whether the original equipment data are uploaded successfully or not, processing results of the original equipment data and at least one of preset operation executed by target Internet of things equipment.
In a possible implementation manner, the target internet of things device continues to send the original device data to the internet of things platform only after determining that the previous original device data is successfully uploaded, so that the internet of things platform needs to send the issued data to the target internet of things device after processing the received target device data, and the issued data is used for indicating that the previous original device data is successfully uploaded, so that the target internet of things device can continue to upload the original device data to the internet of things platform.
Optionally, the issued data may also indicate a processing result of the internet of things platform on the raw device data, that is, the internet of things platform converts the received raw device data into target device data, and after processing the target device data, the processing result may be fed back to the target internet of things device, so that the target internet of things device obtains the processing result. Illustratively, the internet of things device sends a request data to the internet of things platform for obtaining information, for example, the time of the internet of things platform, and after the internet of things platform processes the request data, the internet of things device generates an issue data, where the issue data includes the time of the internet of things platform, i.e., indicates a processing result of the request data.
Optionally, when the internet of things platform needs to control the internet of things device to execute some operations, corresponding issued data (i.e., an instruction) needs to be generated, and the instruction may be used to control the target internet of things device to execute a preset operation. For example, the preset operation may be to upload data to the internet of things platform, or to collect related data.
And secondly, calling a second interface of the target script through the target script engine, analyzing the issued data and generating target issued data, wherein the target issued data adopts a first data format, and the second interface indicates to convert the second data format into the first data format.
The issued data is data sent by the internet of things platform to the target internet of things equipment and is in the second data format, but the target internet of things equipment cannot directly identify the issued data in the second data format, so that the issued data needs to be analyzed by calling a target script to generate the target issued data in the first data format.
In a possible implementation manner, when the internet of things platform issues data to a target internet of things device, a target device group to which the target internet of things device belongs is determined according to a device ID of the target internet of things device, so that a target script engine and a target script are determined, a second interface of the target script is called through the target script engine, the issued data is analyzed, and the target issued data in a first data format is generated.
Illustratively, the issued data may be
The target delivered data obtained after the delivered data is subjected to script parsing may be "0 x0000001400c 8".
And thirdly, sending target issuing data to the target Internet of things equipment.
In a possible implementation manner, the internet of things platform sends target issuing data generated after passing through the target script engine to the target internet of things equipment.
In the embodiment, the target script is divided into the first interface and the second interface according to the data transmission direction, so that the first interface is called when the target internet of things device uploads original device data, and the first data format is converted into the second data format; or when the Internet of things platform issues the data, the second interface is called to convert the second data format into the first data format, so that the target Internet of things equipment can directly identify the issued data, and corresponding operation is executed.
Because the target scripts are all written by the device developer of the target internet of things device, there may be a possibility that the device developer writes malicious scripts to illegally obtain some resources of the internet of things platform, and therefore, when the target script engine executes the target scripts, some restrictions need to be set for the process, so that resource information of the internet of things platform is protected.
Illustratively, step 308 may be replaced by step 310 and step 311 on the basis of fig. 3, as shown in fig. 7.

The CPU running time limit is to limit the running time of the target script, and if the running time of the target script exceeds a preset time, for example, the preset time is 10s, the running of the target script is stopped. And limiting the memory occupied amount to limit the memory amount used by the script thread, and stopping running the target script if the memory amount occupied by the running of the target script exceeds a threshold value, such as 20 MB. The script language method restriction means that if there is other related code such as "download" (load) in addition to the code for realizing the data format conversion in the target script, the target script stops running. The script engine framework uses the limitation that if the target script engine is detected to execute the exit (quit) method, the target script engine is stopped.
In a possible implementation manner, when the internet of things platform calls the target script, since the target script is a script uploaded by a device developer, a target thread needs to be separately established, and a corresponding task is executed in the target thread.
And 311, executing the target script through the target script engine in the target thread, analyzing the original equipment data, and generating target equipment data.
In a possible implementation manner, in a target thread, a target script is executed through a target script engine, original device data is analyzed, and target device data is generated, so that the execution condition of the target script engine is monitored in real time, and related resources of the internet of things platform are protected.
Optionally, when the internet of things platform issues data to the internet of things device, a target thread needs to be created while the target script is called, and in the target thread, the target script is executed by the target script engine, and the issued data is analyzed to generate target issued data in the first data format.
Optionally, the content of the thread restriction may be added to the script engine in advance, so that the script engine may monitor the execution situation in real time when executing the corresponding script, and stop running the corresponding script when the thread restriction is violated.
In the embodiment, the target thread is established when the target script is called, the corresponding thread limit is increased, the execution condition of the target script engine is monitored in real time, and the target script is stopped running in time when the thread limit is violated, so that the resources of the platform of the internet of things can be protected.
