[0002] The Industrial Internet represents a new type of infrastructure, application model, and industrial ecosystem that deeply integrates next-generation information and communication technologies with the industrial economy. By comprehensively connecting people, machines, objects, and systems, it builds a new manufacturing and service system that covers the entire industrial chain and value chain, providing a path for the digitalization, networking, and intelligent development of industry and beyond. The Industrial Internet is currently being widely adopted across all industries, with data collection from industrial equipment being a key component. The collected data is a crucial support for applications on various Industrial Internet platforms. Currently, data collection is primarily performed through edge gateways, making the connection and adaptation between edge gateways and platforms particularly important.

[0060] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0061] Regarding the current common connection adaptation method between edge gateways and platforms, the inventors noticed that the existing connection solutions between edge gateways and platforms often directly connect the gateway and the platform for communication. However, due to the differences in gateway manufacturers, types, protocols and data, the formats of communication messages sent when connecting to the platform are often different. The gateway cannot quickly access the platform, and the same gateway often requires secondary development when accessing different industrial Internet platforms, which makes the time cost of deploying the connection between the edge gateway and the platform high. Therefore, it is particularly important to develop an efficient method for connection adaptation between the gateway and the platform.

[0062] In order to solve the above problems, the inventors of this application have designed an edge connection device adaptation method after research. By pre-acquiring a format conversion list including multiple format conversion templates, and then determining the target format conversion template to be used from the format conversion list according to the format of the first communication information and the second communication information of the first Internet of Things platform and the second Internet of Things platform, the target format conversion template is converted into the information format of the second Internet of Things platform through the target format conversion template and sent, so as to achieve fast and convenient connection and adaptation between the first Internet of Things platform and the second Internet of Things platform.

[0063] Figure 1 The flowchart of the edge connection device adaptation method provided by an embodiment of the present invention is shown. The method is executed by an edge connection device adapter device. The edge connection device adapter device can be a connection management device that is separately set and connected between the first IoT platform and the second IoT platform, or it can be the first IoT platform or the second IoT platform. In the process of interactive communication between the first IoT platform and the second IoT platform, the format of the communication information is converted by the first IoT platform or the second IoT platform. Figure 1 As shown, the method includes the following steps:

[0064] Step 110: Obtain a format conversion list, which includes multiple format conversion templates.

[0065] In this step, the format conversion list is a plurality of pre-generated format conversion templates. The format conversion list can be generated by manual writing. The technician writes the conversion methods between the various commonly used formats in this field into the templates respectively. For example, the commonly used formats in this field are XML format and JSON format. Then, two format conversion templates can be written for converting XML format to JSON format and for converting JSON format to XML format. Both format conversion templates contain sub-data commonly used in this field. Sub-data refers to multiple different types of information contained in the same communication information. For example, the communication information in XML format can contain GatewaySrv, PlatformAddr and PlcProtocol sub-data. The above sub-data are all commonly used sub-data in this field. The technicians in this field can pre-write the corresponding format conversion method into the format conversion template according to each commonly used sub-data in this field.

[0066] Since the sub-data recording the IP and port in the XML format can simultaneously represent both the IP and port data, while the two data in the JSON format need to be represented by two sub-data, the format conversion template can determine whether the entry in the XML format contains two data by segmentation. If so, the port data is added as an independent entry GatewayComm. Those skilled in the art can make adaptive adjustments to the format conversion method in the conversion template according to the characteristics of different formats based on actual conditions to ensure stability after format conversion, including but not limited to splitting, merging and changing the sub-data, which is not specifically limited in the embodiments of the present application.

[0067] In this step, obtaining the format conversion list refers to reading the data in the format conversion list for backup, providing a data basis for subsequent steps.

[0068] Step 120: Acquire first communication information of the first Internet of Things platform and second communication information of the second Internet of Things platform.

[0069] In this step, the first Internet of Things platform and the second Internet of Things platform can be gateways or industrial software running on the industrial Internet platform, or any other virtual platform or device with a software operating environment. The device that runs the method proposed in this application can be the first Internet of Things platform or the second Internet of Things platform itself, or it can be an additional device that undertakes connection transfer between the first Internet of Things platform and the second Internet of Things platform. The embodiments of this application do not specifically limit this.

[0070] In this step, obtaining the first communication information of the first Internet of Things platform refers to receiving and obtaining the communication information of the first Internet of Things platform. It can be obtained by directly establishing a connection with the first Internet of Things platform, or by running the method proposed in this application on the first Internet of Things platform or the second Internet of Things platform. It can also be run on an additional device and use the additional device as a transit to obtain the first communication information and the second communication information of the first Internet of Things platform and the second Internet of Things platform. The same applies to the second Internet of Things platform. For example, the first Internet of Things platform is connected to the device running the method proposed in this application, and the second Internet of Things platform is connected to the device running the method proposed in this application, that is, the device running the method proposed in this application serves as a transit between the first Internet of Things platform and the second Internet of Things platform. At this time, the communication information between the first Internet of Things platform and the second Internet of Things platform is transmitted through the device running the method proposed in this application, and the first communication information of the first Internet of Things platform and the second communication information of the second Internet of Things platform can be easily obtained.

[0071] In this step, the connection between the first IoT platform, the second IoT platform and the device running the method proposed in this application can be based on the Internet Protocol (Internet Protocol), such as the MQTT protocol, AMQP protocol and CoAP protocol, etc., or data can be directly obtained through a serial port-based data transmission protocol. This application does not make any special restrictions on this.

[0072] In this step, there may be multiple first IoT platforms and second IoT platforms. The device running the method proposed in this application can connect to multiple first IoT platforms and second IoT platforms through any connection method or protocol. The embodiment of this application does not specifically limit the number of first IoT platforms and second IoT platforms.

[0073] Step 130: Determine information characteristics of the first communication information and a second format of the second communication information based on the first communication information and the second communication information, where the information characteristics include the first format of the first communication information.

[0074] In this step, based on the first communication information and the second communication information obtained in step 120, the features and formats of the first communication information and the second communication information are analyzed to determine the formats of the first communication information and the second communication information, and at the same time obtain other information features of the first communication information.

[0075] In this step, the information feature refers to a set of data that may include features such as the format, data type, and number of entries of the first communication information. The data in the information feature may be obtained by performing data analysis or data classification on the first communication information.

[0076] The first format and the second format are text formats of the first information and the second information. For example, the first format and the second format may be json, xml or sql. The first format and the second format may be identified by any format identification method.

[0077] Step 140: Determine a target format conversion template from the multiple format conversion templates in the format conversion list according to the information feature and the second format.

[0078] In this step, the target format conversion template can be determined in the format conversion list according to the first format included in the second format information feature. Specifically, one or more format conversion templates that convert the first format into other formats can be screened out from the format conversion list according to the first format, and then a format conversion template that converts the first format into the second format can be determined from the screened out one or more format conversion templates according to the second format. Alternatively, the format conversion template that converts the first format into the second format can be directly retrieved from the format conversion list according to the first format and the second format. Specifically, different methods can be adopted according to actual needs to determine the required target format conversion template from the format conversion list according to the first format and the second format, and this embodiment of the present application is not particularly limited to this.

[0079] Step 150: Convert the first format of the first communication information into a second format according to the target format conversion template.

[0080] In this step, the method of converting the first format of the first communication information into the second format according to the target format conversion template determined in step 140 can be specifically as follows: each sub-data contained in the first communication information is input into the target format conversion template, and each sub-data is converted in the target format conversion template and output to form the first information in a new second format. For example, if the first format is xml format and the second format is json format, the first information in xml format includes two sub-data, GatewaySrv and PlatformAddr, then the target format conversion template for converting the xml format into the json format includes conversion statements for converting the sub-data GatewaySrv and PlatformAddr in xml format into sub-data GatewaySrv and PlatformAddr in json format respectively, and finally the sub-data GatewaySrv and PlatformAddr in json format are output through the target format conversion template.

[0081] The target conversion template may also adopt other conversion methods to ensure that each sub-data contained in the first communication information can be converted into a corresponding format, that is, any conversion method that extracts data from the first communication information and places the data into a new format can be adopted. The embodiment of the present application does not specifically limit this.

[0082] Step 160: Send the first communication information in the second format to the second Internet of Things platform.

[0083] In this step, the first communication information converted into the second format is sent to the second Internet of Things platform. At this time, the format of the first communication information is consistent with the format that can be recognized by the second Internet of Things platform.

[0084] Among them, the sending of the first communication information in the second format of the first Internet of Things platform to the second Internet of Things platform can be one-to-one, that is, one first Internet of Things platform corresponds to one second Internet of Things platform for sending, or it can be one-to-many, many-to-one or many-to-many. The embodiment of the present application does not specifically limit the number of first information sent after format conversion.

[0085] By obtaining a pre-set format conversion list including multiple format conversion templates, and obtaining the first communication information of the first Internet of Things platform and the second communication information of the second Internet of Things platform and obtaining the first format of the first communication information and the second format of the second communication information, it can be known that the format that the second Internet of Things platform can recognize is the second format, and the target format conversion template is determined in the format conversion list according to the first format and the second format, and the first format of the first information is converted into the second format that the second Internet of Things platform can recognize according to the target format conversion template and sent to the second Internet of Things platform, so that the second Internet of Things platform can directly recognize the first communication information sent by the first Internet of Things platform, without the need to modify the first Internet of Things platform or the second Internet of Things platform, thereby shortening the time for connection deployment between devices and reducing the difficulty and cost of connection deployment between devices.

[0086] like Figure 2 As shown, in one embodiment of the present application, step 130 further includes:

[0087] Step 131: Identify the first communication information, determine the number of sub-data included in the first communication information, and use the number and the first format as information features.

[0088] Depending on the first format of the first communication information, the method for identifying the number of sub-data contained in the first communication information also varies. Conventional methods exist for indexing and querying data for different information formats. Alternatively, a text keyword search method can be used to identify the number of sub-data contained in the first communication information. For example, if the first communication information in XML format includes the sub-data GatewaySrv, PlatformAddr, CpuUser, CpuSys, and MemFree, a query list containing all possible fields in this field is established based on conventional communication information types used in industrial equipment data collection. Based on the query list, the corresponding fields GatewaySrv, PlatformAddr, CpuUser, CpuSys, and MemFree are sequentially queried in the first communication information. The number of sub-data is then determined based on the query results and the format of the first communication information. Similarly, the above query method can be used to obtain the number of sub-data for first communication information in other formats, as long as the format of the first communication information is readable text. Different methods can be used to identify the number of sub-data in the first communication information based on actual circumstances, and this is not specifically limited in this embodiment of the present application.

[0089] like Figure 2 As shown, in one embodiment of the present application, before step 140, the following steps are further included:

[0090] Step 1401: Determine a format conversion template group from a format conversion list according to the quantity, where the format conversion template group includes at least one format conversion template for converting sub-data of the quantity.

[0091] Among them, the format conversion list should include multiple format conversion templates containing different numbers of sub-data. For example, the first format conversion template in the format conversion list contains 2 sub-data, GatewaySrv and PlatformAddr, and the second format conversion template contains 6 sub-data, namely GatewaySrv, PlatformAddr, CpuUser, CpuSys, MemFree, and MemUsed. If the number of sub-data contained in the identified first communication information is 6, all format conversion templates containing 6 sub-data can be determined from the format conversion list as a format conversion template group, that is, the format conversion template group includes the above-mentioned second format conversion template, but does not include the above-mentioned first format conversion template.

[0092] like Figure 2 As shown, in one embodiment of the present application, step 140 further includes:

[0093] Step 141: Determine a target format conversion template from the format conversion template group according to the information feature and the second format.

[0094] The format conversion template group is determined by the number of sub-data included in the information feature. That is, the format conversion template group includes multiple format conversion templates for converting to different formats, and each format conversion template performs format conversion on the same number of sub-data. By finding a format conversion template in the format conversion template group that is used for converting to the second format, the format conversion template can be determined as the target format conversion template.

[0095] Through steps 131, 1401, and 141, the number of sub-data in the first communication information is added to the information feature as a condition for determining the format conversion template, so that the number of sub-data of the target format conversion template finally determined is consistent with that of the first communication information. This makes it less likely for the first communication information to make errors due to the mismatch in the number of sub-data when the format is converted through the target format conversion template, thereby improving the stability of the format conversion.

[0096] like Figure 3 As shown, in one embodiment of the present application, step 130 further includes:

[0097] Step 132: Identify the first communication information, determine the type of sub-data included in the first communication information, and use the type and the first format as information features.

[0098] Various methods can be used to identify the types of sub-data contained in the first communication information. The purpose is to obtain the types of all sub-data contained in the first communication information as a basis for identification in subsequent steps. For example, if the first communication information in JSON format includes two sub-data items, PlatformAddr and PlcProtocol, then after identification, the types of sub-data contained in the first communication information are PlatformAddr and PlcProtocol. Various methods can be used to identify the types of sub-data contained in the first communication information. For example, the names of sub-data types commonly used in the field are sequentially searched. If the name of a sub-data type exists in the first communication information, it is understood that the first communication information includes sub-data of this type. The search is repeated until all names of sub-data types commonly used in the field are searched, and the names of the sub-data types found are stored in the information feature. Depending on the actual situation, other methods can also be used to identify the types of sub-data contained in the first communication information. For example, a recognition model is generated through machine learning combined with information on the types of sub-data commonly used in the field, and the types of sub-data contained in the first communication information are identified using the recognition model. This embodiment of the present application is not particularly limited in this regard.

[0099] like Figure 3 As shown, in one embodiment of the present application, before step 140, the following steps are further included:

[0100] Step 1402: Determine a format conversion template group from the format conversion list according to the category, where the format conversion template group includes at least one format conversion template for converting sub-data of the category.

[0101] Among them, the format conversion list should include multiple format conversion templates containing different types of sub-data. For example, the first format conversion template in the format conversion list includes the sub-data PlatformAddr and PlcProtocol, and the second format conversion template includes the sub-data MemFree and MemUsed. If it is identified that the data types contained in the first communication information are PlatformAddr and PlcProtocol, then all format conversion templates containing data of the types PlatformAddr and PlcProtocol can be determined from the format conversion list as a format conversion template group, that is, the format conversion template group includes the above-mentioned first format conversion template, but does not include the above-mentioned second format conversion template.

[0102] like Figure 3 As shown, in one embodiment of the present application, step 140 further includes:

[0103] Step 142: Determine a target format conversion template from the format conversion template group according to the information feature and the second format.

[0104] The format conversion template group is determined by the type of sub-data included in the information feature. That is, the format conversion template group includes multiple format conversion templates for converting to different formats, and each format conversion template performs format conversion on the same type of sub-data. By finding a format conversion template in the format conversion template group that is used for converting to the second format, it can be determined that this format conversion template is the target format conversion template.

[0105] Among them, step 131 can be executed simultaneously with step 132 or in any order. When step 131 and step 132 are executed for the same first communication information, the information feature includes both quantity and type. Then, in the subsequent steps, when determining the format conversion template group, the format conversion templates included in the format conversion template group should satisfy that both the quantity and type are consistent with the quantity and type in the information feature, and step 141 and step 142 can only execute any one of them. Those skilled in the art can make the most favorable order adjustment for the above steps to determine the target format conversion template according to actual conditions. The embodiment of the present application does not specifically limit the execution order of the above steps.

[0106] Through steps 132, 1402, and 142, the type of sub-data in the first communication information is added to the information features as a condition for determining the format conversion template, so that the type of sub-data of the target format conversion template finally determined is consistent with that of the first communication information. This makes it less likely for the first communication information to make errors due to different types of sub-data when format conversion is performed through the target format conversion template, thereby improving the stability of the format conversion.

[0107] like Figure 4 As shown, in one embodiment of the present application, step 130 further includes:

[0108] Step 131: Identify the first communication information, determine the number of sub-data contained in the first communication information, and use the number and the first format as information features;

[0109] Step 132: Identify the first communication information, determine the type of sub-data included in the first communication information, and use the type and the first format as information features.

[0110] By simultaneously taking the quantity and type of the sub-data as information features, the information features include more information in the first communication information, so that the subsequent step of determining the format conversion template can be more accurate.

[0111] like Figure 4 As shown, in one embodiment of the present application, before step 140, the following steps are further included:

[0112] Step 1401: Determine a format conversion template group from a format conversion list according to the quantity, where the format conversion template group includes at least one format conversion template for converting sub-data of the quantity;

[0113] Step 1402: Determine a format conversion template group from the format conversion list according to the category, where the format conversion template group includes at least one format conversion template for converting sub-data of the category.

[0114] In step 1401 and step 1402, those skilled in the art may determine the format conversion template group in the format conversion list based on quantity and type in different ways or orders according to actual circumstances. For example, the format conversion template group may be determined based on both quantity and type, or may be determined based on both quantity and type separately to obtain two format conversion template groups. The purpose is to determine the most appropriate format conversion template group by adding more parameters that conform to the first communication information, thereby providing a more accurate data basis for determining the target format conversion template in subsequent steps.

[0115] By determining the format conversion template group in the format conversion list by quantity and type, the target format conversion template can be determined more accurately in subsequent steps.

[0116] like Figure 4 As shown, in one embodiment of the present application, step 140 further includes:

[0117] Step 141: Determine a target format conversion template from the format conversion template group according to the information feature and the second format.

[0118] like Figure 5 As shown, in one embodiment of the present application, step 140 further includes:

[0119] Step 143: Determine a preliminary format conversion template from the format conversion list according to the first format, where the preliminary format conversion template includes at least one format conversion template for converting the first format into another format;

[0120] Step 144: Determine a target format conversion template from the preliminary format conversion templates according to the second format.

[0121] In step 143, a preliminary format conversion template is determined from a format conversion list based on the first format. The determination is as follows: the format conversion list includes AB, AC, AD, BA, BC, BD, CA, CB, CD, DA, DB, and DC, where A, B, C, and D represent various formats. AB represents a format conversion template for converting from format A to format B. When the first format is B, a format conversion template is required for converting format B. Therefore, templates for converting format B are selected from the format conversion list: BA, BC, and BD. The preliminary format conversion templates then include BA, BC, and BD.

[0122] In step 144, based on the preliminary format conversion template determined in step 133, a format conversion template that converts the first format into the second format is found from the preliminary format conversion templates according to the second format. For example, if the second format is C and the preliminary format conversion templates include BA, BC, and BD, then format conversion template BC can be determined as the target format conversion template.

[0123] Through steps 143 and 144, the determination of the target conversion template follows the basic rules of format conversion, that is, the format conversion order of the template should be consistent with the format conversion order actually required, thereby avoiding the problem of determining a format conversion template with a reversed format conversion order from the format conversion list based on the first format and the second format, and reducing the failure rate during format conversion.

[0124] like Figure 6 As shown, in one embodiment of the present application, before step 120, the following steps are further included:

[0125] Step 1201: Obtain first registration information of a first IoT platform and second registration information of a second IoT platform;

[0126] Step 1202: Determine whether the first registration information of the first IoT platform meets the first condition, and simultaneously determine whether the second registration information of the second IoT platform meets the second condition;

[0127] If the answer is yes, perform the following steps:

[0128] Step 120: Acquire first communication information of the first Internet of Things platform and second communication information of the second Internet of Things platform.

[0129] In step 1201, the first and second registration information may include the software IDs or gateway IDs of the first and second IoT platforms, the manufacturer of the device or software, key parameters of the device or software (software or hardware version number, identification code, etc.), and communication channel information. This information is used to provide identity verification for subsequent steps, determining whether the first IoT platform to which the first registration information belongs, or the second IoT platform to which the second registration information belongs, is the target for the current operation. The content of the first and second registration information may be modified based on actual circumstances, as long as it can provide identification for the device or software, and this embodiment of the application does not impose any specific limitations on this.

[0130] In step 1202, the first condition and the second condition should be set according to the registration information of the target device or software of the current operation. When the first registration information obtained satisfies the first condition, it can be considered that the first Internet of Things platform to which the first registration information belongs is the correct connection target. When the second registration information obtained satisfies the second condition, it can be considered that the second Internet of Things platform to which the second registration information belongs is also the correct connection target, and the subsequent normal connection operation steps can be performed. If the first registration information does not meet the first condition or the second registration information does not meet the second condition, it means that the current first Internet of Things platform and / or second Internet of Things platform may not be the operation target. Those skilled in the art can make corresponding adjustments and corrections in a timely manner. The adjustment and correction methods include but are not limited to replacing the first Internet of Things platform and / or the second Internet of Things platform, checking the connection configuration, etc., and then executing the above steps again until both the first Internet of Things platform and the second Internet of Things platform are determined to be the correct connection targets.

[0131] Through steps 1201 and 1202, before the connection communication between the first IoT platform and the second IoT platform is established, it is verified whether it is the target device or software that needs to be connected for the operation, thereby improving data security and avoiding connection to the wrong device or software that affects normal operation.

[0132] like Figure 6As shown, in one embodiment of the present application, step 1201 further includes:

[0133] Step 12011: Obtain the first ID, first manufacturer, first main parameter, and first communication channel information of the first Internet of Things platform;

[0134] Step 12012: Obtain the second ID, second manufacturer, second main parameters and second communication channel information of the second Internet of Things platform.

[0135] In step 12011 and step 12012, obtaining multiple information as the first registration information and the second registration information can improve the accuracy of the verification in step 1201 to step 1203, and further avoid operating on the wrong device or software.

[0136] like Figure 7 As shown, in one embodiment of the present application, before step 120, the following steps are further included:

[0137] Step 1203: Acquire first historical registration information of the first IoT platform and second historical registration information of the second IoT platform in the previous operation;

[0138] Step 1204: Determine whether the first historical registration information is identical to the first registration information and whether the second historical registration information is identical to the second registration information.

[0139] If the answer is yes, perform the following steps:

[0140] Step 1205 : Determine the historical format conversion template in the previous operation as the target format conversion template, execute step 120 , and then jump to step 150 .

[0141] In step 1203, the first historical registration information of the first IoT platform and the second historical registration information of the second IoT platform in the last operation refer to the registration information of the first IoT platform and the second IoT platform that have been identified as target devices or software during the last normal operation. The purpose is to obtain the registration information of the device or software that was normally operated last time for verification in subsequent steps.

[0142] In step 1204 and step 1205, the first registration information and the second registration information currently obtained are judged. If they are consistent with the registration information of the last normal operation, it can be understood that the target software or device of this operation is consistent with that of the last operation, so their target format conversion template can also use the target format conversion template determined during the last operation.

[0143] Through step 1203, step 1204 and step 1205, the registration information of the software or device of the current operation is compared with the registration information of the software or device of the previous operation. If they are consistent, it can be considered that the software or device of the current operation is the same as the previous one. Therefore, there is no need to repeatedly determine the target format conversion template. The target format conversion template that has been determined in the previous operation can be directly used, which improves the operation efficiency, shortens the operation process, and saves time and cost.
