Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts fall within the protection scope of the present application.

[0077] It should be noted that the term "including" will be used in the embodiments of the present application to indicate the existence of the features stated thereafter, but does not exclude the addition of other features.

[0078] First, before specifically describing the technical solutions provided by the present application, a brief description will be given to the data processing scenario of the Internet of Things gateway involved in the present application.

[0079] Figure 1 Schematic diagram of a data processing scenario of an Internet of Things gateway provided by an embodiment of the present application. Refer to Figure 1 As shown, the data processing scenario of the Internet of Things gateway may include multiple terminal devices 101, a protocol conversion Internet of Things gateway 102, and an Internet of Things cloud platform 103. Among them, the protocol conversion Internet of Things gateway 102 is respectively communicatively connected to each terminal device 101 and the Internet of Things cloud platform 103.

[0080] Exemplarily, for example, the terminal device 101 refers to an integrated energy power supply acquisition terminal device (such as a voltmeter, an ammeter), an integrated energy water supply acquisition terminal device (such as a water meter), and an integrated energy gas and heat acquisition terminal device (such as a gas meter), etc.

[0081] The Internet of Things cloud platform 103 may refer to an Internet of Things master station data center, an Internet of Things master station management system, etc.

[0082] The protocol conversion Internet of Things gateway 102 takes the edge proxy framework as the core, accesses the integrated energy water, electricity, and gas data detection terminal devices below, and docks with the Internet of Things cloud platform 103 (such as the Internet of Things data center and the Internet of Things master station management system) above, provides a device modeling function for the integrated energy field terminal devices, solves the general protocol structure configuration of the terminal devices and the definition of the event processing service model, and achieves the interoperability of the same type of terminal devices.

[0083] Specifically, the protocol conversion Internet of Things gateway 102 may obtain and process the service data collected by each terminal device 101, and forward the processed result to the Internet of Things cloud platform 103 for storage by the Internet of Things cloud platform 103.

[0084] It can be understood that Figure 1 The structure shown is only schematic, and the data processing scenario of the Internet of Things gateway may also include more or fewer components than those shown Figure 1 herein, or have a configuration different from that shown Figure 1 herein. Figure 1 Each component shown herein may be implemented by hardware, software, or a combination thereof.

[0085] The implementation principle and corresponding beneficial effects of the data processing method steps of the Internet of Things gateway provided by the present application will be described below through multiple specific embodiments.

[0086] Figure 2 Flow schematic diagram of a data processing method of an Internet of Things gateway provided by an embodiment of the present application; optionally, the execution subject of this method may be the Figure 1 protocol conversion Internet of Things gateway shown.

[0087] It should be understood that in other embodiments, the order of some steps in the data processing method of the Internet of Things gateway can be interchanged according to actual needs, or some of the steps can also be omitted or deleted. As Figure 2 shown, the method includes:

[0088] S201. Traverse the list of end devices, and obtain the service list predefined in the physical model instances of each terminal device.

[0089] Among them, the list of end devices stores, but is not limited to: communication parameters, identifiers, protocol model instances, and physical model instances of each predefined terminal device, etc. Among them, the physical model is mainly used to describe the data information of each terminal device, and the same type of terminal device uses the same physical model and protocol model. For example, the same type of electric energy meter can use the same predefined physical model to instantiate the physical model of a specific electric energy meter.

[0090] In this way, the device modeling function is provided for all terminal devices at the integrated energy site, avoiding the need for protocol configuration or protocol customization development for different terminal devices to be accessed, resulting in a large amount of repetitive work such as access reuse, debugging, and operation and maintenance of terminal devices, and thus causing the problem of low data processing efficiency of the Internet of Things gateway.

[0091] In this embodiment, the list of end devices provides the definition of end device management service information. For example, the following is a structure instance of a certain terminal device read from the list of end devices:

[0092]

[0093] From the above instance, it can be obtained that from the list of end devices, the end device identifier Id of this terminal device is 10000abcd, the physical model instance is 100001, the protocol model instance is HL, and communication parameters, etc. Among them, the information contained in the communication parameters is as follows:

[0094]

[0095]

[0096] After obtaining the physical model instance of this terminal device, the predefined service list can be continuously read from the physical model instance 100001 of this terminal device. Among them, the service list stores multiple service data to be collected by this terminal device, execution commands when collecting each service data, types of each service data, etc.

[0097] The following is the information contained in the physical model instance 100001 of this terminal device:

[0098]

[0099]

[0100]

[0101]

[0102]

[0103]

[0104]

[0105]

[0106]

[0107]

[0108]

[0109]

[0110]

[0111] Therefore, the service list services can continue to be read from the device model instance 100001 of the terminal device.

[0112] S202. Traverse the service lists of all terminal devices to obtain the execution commands corresponding to the service information of all terminal devices.

[0113] The service information refers to the specific service data to be collected by the terminal device. For example, if the terminal device is an electricity meter, the service information of the electricity meter can be to query the three-phase current of the electricity meter.

[0114] Based on the above embodiments, for example, from the service list services, the service information of the terminal device is obtained as time calibration by electricity meter broadcast, querying the A-phase voltage of the electricity meter, and querying the three-phase current of the electricity meter. Among them, the execution command corresponding to querying the A-phase voltage of the electricity meter is "queryUa".

[0115] S203. Obtain the service data of all terminal devices according to the execution commands corresponding to the service information of all terminal devices and the communication parameters of all terminal devices.

[0116] In this embodiment, according to the information such as the address, port number, and baud rate in the communication parameters of the terminal device in the above embodiment, the execution command "queryUa" corresponding to querying the A-phase voltage of the electric energy meter can be called to obtain the service data collected by the terminal device, that is, the voltage value of the A-phase voltage of the electric energy meter.

[0117] S204. Verify the service data of each terminal device based on the physical model instances of each terminal device.

[0118] Optionally, based on the physical model instance of the terminal device, the voltage value of the A-phase voltage of the electric energy meter of the collected terminal device can also be verified to determine whether the voltage value of the A-phase voltage of the currently collected electric energy meter is within the normal range.

[0119] S205. Send the service analysis result of the terminal device to the Internet of Things cloud platform according to the verification result.

[0120] Optionally, in order to perform an overall analysis of the service data collected by each terminal device to facilitate timely problem discovery. The service analysis result of the terminal device can also be sent to the Internet of Things cloud platform according to the verification result.

[0121] For example, if the service data verification of a certain terminal device fails, an alarm event for the service data of the terminal device can be generated, and the alarm event for the service data of the terminal device can be sent to the Internet of Things cloud platform, so that the user can view and process the alarm event for the service data of the terminal device in a timely manner on the Internet of Things cloud platform, improving the stability and reliability of the operation of the terminal device.

[0122] In summary, the embodiment of the present application provides a data processing method for an Internet of Things gateway. In this solution, mainly the obtained list of terminal devices is traversed first to obtain the communication parameters and physical model instances of each terminal device stored on the list of terminal devices. Among them, the same type of terminal device is instantiated with the same physical model to obtain the physical model instances of each terminal device; that is, according to the device information of the terminal device, multiple different models are constructed, and the terminal devices corresponding to the device information with the same attributes are instantiated with the same model. Then, based on the model instances after instantiation of each terminal device, the service data collected by each terminal device is uniformly managed, improving the processing efficiency of the Internet of Things gateway for various types of service data, and avoiding the problem of low processing efficiency of the Internet of Things gateway for data caused by the need to perform protocol configuration or protocol customization development for different terminal devices to be connected, resulting in a large amount of repetitive work such as terminal device access reuse, debugging, and operation and maintenance.

[0123] In addition, read the pre-defined service list from the physical model instances of each terminal device, traverse the service lists of each terminal device, obtain the execution commands corresponding to the service information of each terminal device, and use the execution commands corresponding to the service information of each terminal device and the communication parameters of each terminal device to obtain the service data of each terminal device. Then, based on the physical model instances of each terminal device, verify the service data of each terminal device. Finally, according to the verification results, send the service analysis results of the terminal device to the IoT cloud platform, realizing the overall analysis of the service data collected by each terminal device to facilitate timely problem discovery.

[0124] The following embodiments will specifically explain how to verify the service data of each terminal device based on the physical model instances of each terminal device in step S204 above.

[0125] Optionally, the physical model instance includes pre-defined dynamic attributes, which are used to limit the range of the service data of each terminal device. In step S204 above, it includes:

[0126] Based on the dynamic attributes in the physical model instances of each terminal device, compare the service data of the terminal device with the pre-defined thresholds in the dynamic attributes to determine whether the service data of each terminal device passes the verification.

[0127] In this embodiment, the physical model will be introduced first.

[0128] Specifically, the physical model is a digital description of the terminal devices (signals) used in the integrated energy system in the physical space. By standardizing the unified modeling method for all terminal devices connected to the Internet of Things, a description model of terminal device data information is constructed to realize a unified description model for all terminal device data in the Internet of Things, and support the interactive application of various business terminal data information in the integrated energy application among business applications, IoT management platforms, and edge IoT agents.

[0129] In this embodiment, the physical model includes but is not limited to: model identifier, static attributes, dynamic attributes, event attributes, and service attributes. Specifically, as shown in Table 1, Table 2, and Table 3.

[0130] Table 1 Static / Dynamic Attribute Structure

[0131] Name Type Required Description identified String Yes Object Model Number of Belonging name Sting Yes Attribute Name accessMode String Yes Release Accessible required String Yes Is Required dataType Sting Yes Data Type property String Yes Static / Dynamic Attribute Differentiation

[0132] Table 2 Event Attribute Structure

[0133]

[0134] Table 3 Service Attribute Structure

[0135]

[0136] In this embodiment, continuing with the physical model instance 100001 of the electric energy meter mentioned in the above embodiment as an example, for the dynamic property "dynamicProperties" in the physical model instance 100001 of the electric energy meter, for example, in the dynamic property "dynamicProperties", the predefined range of the collected "current" is: the minimum value "min" is "0.0001", the maximum value "max" is "99999", and the predefined range of the collected "phase A voltage" is: the minimum value "min" is "0.0001", the maximum value "max" is "99999", etc.

[0137] Therefore, the current collected by the electric energy meter can be compared with the predefined range of "current" in the dynamic property to determine whether the current collected by the electric energy meter falls within the defined range. For example, if the current I1 collected by the electric energy meter at time t1 is 0.00001 A, that is, the current I1 does not fall within the range of [0.0001, 99999], it can be determined that the current I1 collected by the current electric energy meter is abnormal, that is, it fails the verification; if the current I2 collected by the electric energy meter at time t2 is 0.0009 A, that is, the current I2 falls within the range of [0.0001, 99999], it can be determined that the current I2 collected by the current electric energy meter is normal, that is, it passes the verification.

[0138] The following embodiments will specifically explain how to send the service analysis result of the terminal device to the Internet of Things cloud platform according to the verification result in step S205 above.

[0139] Optionally, referring to Figure 3 As shown, the above step S205 includes:

[0140] S301. If the verification result is that the verification fails, an out-of-limit event corresponding to the service data with verification failure is created based on the physical model instance of the terminal device, and the out-of-limit event corresponding to the service data with verification failure and the identifier of the terminal device are sent to the Internet of Things cloud platform.

[0141] Based on the above embodiment, for example, if the current I1 collected by the electric energy meter at time t1 is 0.00001 A and fails the verification, an out-of-limit event corresponding to the verification current I1 can be created based on the physical model instance of the electric energy meter, and the out-of-limit event corresponding to the current I1 and the identifier 10000abcd of the electric energy meter are sent to the Internet of Things cloud platform, so that users can view and process the out-of-limit event of the current I1 collected by the electric energy meter in a timely manner on the Internet of Things cloud platform, improving the stability and reliability of the operation of the electric energy meter.

[0142] S302. If the verification result is passed, save the business data with passed verification to the data sharing library.

[0143] S303. Analyze and process the business data with passed verification to obtain an analysis result, and upload the analysis result, the business data with passed verification, and the identifier of the terminal device to the Internet of Things cloud platform.

[0144] Exemplarily, for example, the analysis result may refer to the prediction of the current values collected by the electricity meter in a future period of time, so as to evaluate the electricity consumption situation according to the prediction result.

[0145] Based on the above embodiments, for example, if the current I2 = 0.0009A collected by the electricity meter at time t2 passes the verification, the current I2 collected by the electricity meter can be saved to the data sharing library, and the current I2 collected by the electricity meter is analyzed and processed to obtain an analysis result. Then, the analysis result, the current I2 with passed verification, and the identifier 10000abcd of the electricity meter are uploaded to the Internet of Things cloud platform, so that the user can view the operation status of the electricity meter 10000abcd on the Internet of Things cloud platform in a timely manner.

[0146] Optionally, in the present application, in order to solve the problem that the protocol conversion Internet of Things gateways provided in the prior art do not provide a unified edge computing framework integrating container technology, resulting in the inability to manage each application program running on the protocol conversion Internet of Things gateway, making the development and maintenance of edge computing functions difficult, it is proposed to adopt the Docker integrated container management technology to integrate the event processing application program, the edge computing application program, and the protocol application program running on the protocol conversion Internet of Things gateway into the Docker container, so as to realize functions such as business isolation, update, operation and maintenance, and service startup of each application program, thereby improving the data processing efficiency of the Internet of Things gateway.

[0147] First, introduce the functions of the event processing application program.

[0148] Optionally, an event processing application program runs on the protocol conversion Internet of Things gateway; creating an out-of-limit event corresponding to the business data with failed verification based on the physical model instance of the terminal device in the above step S301 includes:

[0149] The event processing application program creates an out-of-limit event corresponding to the business data with failed verification based on the physical model instance of the terminal device, and returns the out-of-limit event corresponding to the business data with failed verification.

[0150] In this embodiment, for example, the event processing application APP can create an out-of-limit event corresponding to the current I1 with failed verification based on the event attributes in the physical model instance 100001 of the electricity meter (shown in Table 2 above), and return the out-of-limit event corresponding to the current I1. In this way, it is possible for the dedicated event processing application APP to create out-of-limit events corresponding to business data with failed verification, meeting different business processing requirements and effectively improving the data processing efficiency of the IoT gateway.

[0151] Second, introduce the functions of the edge computing application.

[0153] The edge computing application analyzes and processes the verified business data to obtain an analysis result and returns the analysis result.

[0154] In this embodiment, for example, the edge computing application APP can analyze and process the verified business data I2 to obtain an analysis result and return the analysis result. In this way, it is possible for the dedicated edge computing application APP to perform edge computing on the verified business data, effectively improving the data processing efficiency of the IoT gateway.

[0155] Third, introduce the functions of the protocol application.

[0156] Optionally, the protocol conversion IoT gateway runs a protocol application; as shown in Figure 4 The above step S203 analyzes and processes the verified business data to obtain an analysis result, including:

[0157] S401. If the terminal device is a non-intelligent terminal device, send the execution command corresponding to the service information of the terminal device and the communication parameters of the terminal device to the protocol application.

[0158] It should be understood that if a certain terminal device is an intelligent terminal device, then the terminal device has the function of data communication with the IoT gateway based on its own protocol type.

[0159] In this embodiment, if a certain terminal device is a non-intelligent terminal device, it is necessary to assemble the execution command corresponding to the service information of the terminal device and the communication parameters of the terminal device, and publish the assembled result to the data bus.

[0160] S402. The protocol application determines the target protocol type corresponding to the execution command according to the pre-defined protocol model.

[0161] Among them, the protocol model is used to characterize the mapping relationship between execution commands and protocol instructions.

[0162] In this embodiment, the protocol model mainly targets terminal devices that only support protocol communication for data exchange, such as terminal devices using communication methods like Modbus and DLT645. In the definition of the thing model, for this type of terminal device, it is impossible to directly send commands to obtain corresponding attribute data. Instead, corresponding information needs to be obtained through protocol communication parsing. Therefore, it is necessary to define the mapping relationship between commands and protocol instructions for this type of terminal device. The protocol command structure is as shown in the following example:

[0163]

[0164]

[0165]

[0166] S403. The protocol application program obtains the service data of the terminal device according to the target protocol type and returns the service data of the terminal device.

[0167] Based on the above embodiment, the protocol application program APP receives the assembled result from the data bus, determines the target protocol type corresponding to the execution command included in the assembled result according to the assembled result and the pre-defined protocol model, and then, according to the target protocol type, obtains the service data collected by the terminal device and returns the service data collected by the terminal device in the form of a key-value pair result.

[0168] The following embodiments will specifically explain how to configure to obtain an instance of the thing model of a certain terminal device.

[0169] Optionally, as shown in Figure 5 before the above step S201, it further includes:

[0170] S501. Determine the target thing model corresponding to the terminal device according to the type of the terminal device input by the user.

[0171] In this embodiment, the same type of terminal device uses the same thing model. For example, if the terminal device A to be connected to the Internet of Things is an electric energy meter, that is, the user inputs the type of the terminal device A as an electric energy meter, then based on the type of the terminal device A, the target thing model corresponding to the terminal device A can be further determined as 100001.

[0172] S502. Establish an instance of the thing model of the terminal device according to the configuration information of the terminal device input by the user and the target thing model.

[0173] Among them, the device information of the terminal device may include, but is not limited to: static attributes, dynamic attributes, event attributes, and service attributes. Among them, the service attributes include: service information and the execution commands corresponding to the service information.

[0174] S503. Add the communication parameters of the terminal device and the physical model instance to the list of terminal devices.

[0175] In this embodiment, the configuration information such as the static attributes, dynamic attributes, event attributes, and service attributes of the terminal device A input by the user can be filled into the corresponding configuration areas in the determined target physical model respectively to construct the physical model instance of the terminal device A. At the same time, the communication parameters of the terminal device A and the physical model instance are added to the list of terminal devices.

[0181] S605. Send the execution commands corresponding to the service information of the terminal device and the communication parameters of the terminal device to the protocol application program.

[0182] S606. The protocol application program determines the target protocol type corresponding to the execution command according to the predefined protocol model, obtains the service data of the terminal device according to the target protocol type, and returns the service data of the terminal device.

[0183] S607. Based on the physical model instance of each terminal device, verify the service data of each terminal device to obtain a verification result.

[0184] S608. If the verification result fails, the event handling application creates an out-of-limit event corresponding to the business data with failed verification based on the physical model instance of the terminal device, returns the out-of-limit event corresponding to the business data with failed verification, and sends the out-of-limit event corresponding to the business data with failed verification and the identifier of the terminal device to the Internet of Things cloud platform.

[0185] S609. If the verification result passes, save the business data with passed verification to the data sharing library.

[0186] S610. The edge computing application analyzes and processes the business data with passed verification to obtain an analysis result, returns the analysis result, and uploads the analysis result, the business data with passed verification, and the identifier of the terminal device to the Internet of Things cloud platform.

[0187] Optionally, the overall implementation steps and the beneficial effects of the data processing method of the Internet of Things gateway provided in this application embodiment have been described in detail in the foregoing specific embodiments, and will not be elaborated herein one by one.

[0188] Optionally, this application also proposes that a power-off protection module can be added to the protocol conversion Internet of Things gateway structure design, that is, a thin-film battery installation is added to the protocol conversion Internet of Things gateway structure design to ensure that it has a power-off protection function without increasing the device installation space. The designed backup power supply supports a power supply time of more than 30 minutes, realizes the finishing work of data transmission and processing between the gateway device and the Internet of Things cloud platform, ensures that the Internet of Things cloud platform clearly knows the reason for the device operation failure, provides a decision reference for device maintenance processing, and integrates device power-off alarms as Figure 7 shown.

[0189] S701. The power supply service module of the protocol conversion Internet of Things gateway obtains the operation data of each terminal device.

[0190] S702. The protocol conversion Internet of Things gateway uploads the operation data of each terminal device to the Internet of Things cloud platform.

[0195] S708. Determine whether the substation has lost power.

[0196] S709. If so, the Internet of Things cloud platform generates a power loss alarm.

[0197] In this embodiment, it solves the problem in the prior art that the protocol conversion Internet of Things gateway does not provide sufficient design considerations for its own anomalies such as the power supply state, resulting in the inability to distinguish between power supply and network communication failures.
