Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0051] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0052] First, a brief introduction to the related background art:

[0053] The Internet of Things device can access the system for data collection, and the gateway is usually mainly responsible for the monitoring and control functions of the device. The gateway plays a pivotal role in the device end and service display end in the system. Taking the Internet of Things device as a circuit breaker as an example, with the development of science and technology and the diversification of people's demand for power systems, the types and functions of circuit breaker devices are becoming more and more rich, and the requirements for circuit breaker gateway are becoming higher and higher. When a new circuit breaker product needs to be connected to the power system, the current common solution is to modify the collection strategy, collection point, and reporting format part in the gateway software to be compatible, which requires a large number of modifications to the gateway software and then repeated testing and deployment to realize the compatibility of the new circuit breaker product. The deployment means reprogramming the business code program into an executable file and deploying it on the gateway. It must be operated by a professional software development engineer.

[0054] The problem caused by modifying the gateway software after adding new devices is:

[0055] 1. The functions of various types of devices differ greatly, so the point table, collection strategy, packaging format, etc. need to modify the software, and the deployment also needs the participation of professional software personnel, which increases the software implementation cost of the project in this process.

[0056] 2. The readability, scalability and maintainability of the gateway software deteriorate in the iteration process.

[0057] Based on the existence of this problem, the present scheme provides a device access method, which introduces DSL (Domain Specific Language), when a new device needs to access the network, by converting the point table information of the new device into a DSL file, the gateway execution code can be quickly updated, on the one hand, the threshold of generating a DSL file is low, which is convenient for maintenance personnel to handle, on the other hand, when updating the gateway execution code through the DSL way, the access of the new device does not need to make a lot of changes to the related configuration information of other devices that have been accessed, so the modification of the gateway execution code is small, which reduces the software implementation cost.

[0058] Figure 1 A flowchart of a device access method provided by an embodiment of the present application; the execution subject of the method can be a terminal, a server or other computer device. As shown in the figure, Figure 1 The method can include:

[0059] S101, obtaining the point table information of the current device to be accessed, and generating the point position description information of the device to be accessed according to the point table information, the point position description information including the related configuration information of the target system accessed by the device to be accessed.

[0060] The method can be applied to the access processing of the related system of the Internet of Things device. The Internet of Things device includes but is not limited to: circuit breaker device, sensor device, etc.

[0061] The target system can refer to the system to be accessed by the device to be accessed, for example, when the device to be accessed is a circuit breaker, the target system can be a power system.

[0062] When a new device needs to access the target system, the point position description information of the device to be accessed can be generated based on the obtained point table information of the current device to be accessed.

[0063] It is worth noting that the point table of the Internet of Things device plays an important role in the automation control system, which usually refers to the list or summary of each variable point in the system. These variable points can include switch value input point (DI), switch value output point (DO), analog value input point (AI), analog value output point (AO) and communication point, etc.

[0064] In an industrial Internet of Things (IIoT) environment, the point table of an Internet of Things device can also contain other information related to device communication, data collection, remote control, etc. These information is crucial for realizing functions such as real-time monitoring, fault diagnosis, predictive maintenance, etc. of the device.

[0065] Specifically, the point table of an Internet of Things device can contain the following information:

[0066] Device basic information: including device name, model, manufacturer, production date, etc.

[0067] Variable information: including variable name, data type (such as digital quantity, analog quantity, etc.), measurement range, unit, etc.

[0068] Communication information: including communication protocol, communication address (such as IP address, MAC address, etc.), port number, etc.

[0069] Control information: including control commands, control parameters, etc. for realizing remote control functions.

[0070] Collection information: including collection frequency, collection method (such as timed collection, triggered collection, etc.) for realizing real-time data collection functions.

[0071] The point table information of the device to be accessed can be directly obtained from the database, and by converting the point table information, the point position description information of the device to be accessed can be generated, and the point position description information can include the related configuration information required by the device to be accessed when accessing the target system. The related configuration information can include one or more of the point table information.

[0072] S102, updating the device point position description information currently configured in the target system according to the point position description information of the device to be accessed, to obtain updated device point position description information.

[0073] Before the device to be accessed accesses the target system, some devices have been accessed in the target system, and the point position description information of the accessed devices has been configured.

[0074] In this embodiment, the point position description information of the device to be accessed can be used to update the device point position description information currently configured in the target system, so as to configure the point position description information of the device to be accessed in the target system.

[0075] By this way, the point position description information of the device to be accessed can be used to quickly update the device point position description information currently configured in the target system, without the need to modify a large amount of code of the gateway corresponding to the devices currently accessed in the target system, which can reduce development cost.

[0076] S103, generating target gateway execution code according to the updated device point position description information and running the target gateway execution code to access the current to-be-accessed device to the target system and collect data of the device accessed to the target system.

[0077] Optionally, based on the obtained updated device point position description information, the updated device point position description information can be compiled into target gateway execution code or downloaded into a gateway storage database, so that the target gateway execution code is executed by gateway software, and in the process of code execution, the to-be-accessed device is accessed to the target system, and data collection is performed according to the point position description information of each device accessed to the target system in the target gateway execution code. Thus, the compatibility of the to-be-accessed device is quickly completed.

[0078] To sum up, the device access method provided in the embodiment includes: obtaining point table information of a current to-be-accessed device, and generating point position description information of the to-be-accessed device according to the point table information, the point position description information including relevant configuration information of the to-be-accessed device accessing a target system; updating device point position description information currently configured for the target system according to the point position description information of the to-be-accessed device, to obtain updated device point position description information; generating target gateway execution code according to the updated device point position description information and running the target gateway execution code to access the current to-be-accessed device to the target system and collect data of the device accessed to the target system. When a new device needs to access the system, the point table information of the to-be-accessed device can be obtained to convert and generate the point position description information of the to-be-accessed device, so that the device point position description information currently configured for the system can be quickly updated based on the point position description information of the to-be-accessed device. In this way, the information compatibility of the new device can be realized without modifying the gateway execution code currently configured for the system, and the development cost is reduced.

[0079] Figure 2 Another flowchart of a device access method provided in the embodiment of the application is shown in the figure. Optionally, in step S101, generating the point position description information of the to-be-accessed device according to the point table information can include:

[0080] S201, extracting relevant configuration information of the to-be-accessed device accessing the target system from the point table information; the relevant configuration information at least including device information of the to-be-accessed device, a data collection strategy, a data packaging strategy, and a data reporting strategy.

[0081] Based on the above description of the point table information, the relevant configuration information required by the to-be-accessed device when accessing the target system can be extracted from the point table information of the to-be-accessed device. In the embodiment, the extracted relevant configuration information can include but is not limited to device information of the to-be-accessed device, a data collection strategy, a data packaging strategy, and a data reporting strategy.

[0082] The device information of the device to be accessed can include the category of the device, a point address, a point data length, a point type, a point description, a point data format, and the like; the data collection strategy can refer to the rate, frequency, content, and the like of the data collection of the gateway to the device; the collection strategies of different devices can be different; the data packaging strategy can refer to packaging the collected original data of the device into a preset data format, facilitating the data recognition and analysis of the server, and the preset data format can be, for example, a JSON format; and the data reporting strategy can refer to uploading the packaged data to the server for storage and display.

[0083] The category of the device can be, for example, a circuit breaker, a temperature and humidity sensor, an access control sensor, and the like; the point address of the temperature and humidity sensor can include, for example, a temperature point and a humidity point; and the point address of the access control sensor can include, for example, a switch point.

[0084] In some embodiments, the data collection strategies, the data packaging strategies, and the data reporting strategies corresponding to different devices can be completely different, but can also be the same. In particular, the data packaging strategies and the data reporting strategies can be shared by multiple devices.

[0085] S202, generating point description information of the device to be accessed according to the related configuration information and the domain-specific language template.

[0086] Optionally, the related configuration information extracted from the point table information can be converted into the point description information of the device to be accessed according to the extracted related configuration information of the device to be accessed and the domain-specific language template.

[0087] The domain-specific language template can refer to a DSL basic template. DSL is a computer programming language with limited expressiveness for a specific field. It is different from general-purpose computer languages (GPLs) and is only used in certain specific fields, such as HTML for displaying web pages and Emacs LISP language used by Emacs.

[0088] The design goal of DSL is to improve development efficiency, abstract the construction model through DSL, extract common code, and reduce repetitive labor. In addition, domain experts can build the functions of the system through DSL, and DSL can make up for the limitations of the host language.

[0089] Optionally, in step S202, the point description information of the device to be accessed can be generated according to the related configuration information and the domain-specific language template, which can include matching the related configuration information to the corresponding positions in the domain-specific language template to generate the point description information adapted to the device to be accessed.

[0090] The basic common code is provided in the domain-specific language template, and only the related configuration information of the device to be accessed needs to be filled in the corresponding position in the domain-specific language template to generate the point location description information adapted to the device to be accessed.

[0091] That is, the related basic code is provided in the domain-specific language template, and only the related configuration information of the device to be accessed needs to be filled in the corresponding position in the template to obtain the point location description language corresponding to the device to be accessed.

[0092] The point location description information corresponding to the device to be accessed is generated from the point table information of the device to be accessed by the above manner, which can be understood as generating the DSL file corresponding to the device to be accessed. Since the basic common code is provided in the DSL template, only the extracted related configuration information of the device to be accessed needs to be matched to the template to quickly generate the DSL file of the device to be accessed. For the developer, only the provided DSL basic template can realize the compatible processing of the new device, and the learning threshold is low.

[0093] Optionally, in step S102, the device point location description information currently configured by the target system is updated according to the point location description information of the device to be accessed to obtain updated device point location description information, which can include: adding the point location description information of the device to be accessed to the device point location description information currently configured to obtain the updated device point location description information.

[0094] In some embodiments, the device corresponding point location description information (DSL) file is generated for each device in the present scheme, that is, one DSL file is generated for each device, and the device point location description information currently configured by the target system includes the DSL files corresponding to the devices that have accessed the target system.

[0095] The DSL file corresponding to the device to be accessed can be used to update the DSL file currently configured by the target system to obtain an updated DSL file.

[0096] It is worth noting that the form of the generated DSL file can be a piece of other language, a TXT text file, or an EXECL table, and the file form is not limited.

[0097] Optionally, the currently configured device point location description information includes private point location description information and public point location description information; the step of adding the point location description information of the device to be accessed into the currently configured device point location description information to obtain updated device point location description information can include: if the public point location description information in the point location description information of the device to be accessed already exists in the public point location description information of the currently configured device point location description information, then the private point location description information in the point location description information of the device to be accessed is added into the private point location description information of the currently configured device point location description information.

[0098] In an implementable manner, the currently configured device point location description information of the target system can be divided into private point location description information and public point location description information. The public point location description information can refer to point location description information common to all accessed devices, for example, data packaging strategy, data reporting strategy, etc. It is possible that the data packaging strategy and the data reporting strategy of all devices are completely the same, and thus the same can be stored as public point location description information. The private point location description information is used to store part of point location information specific to each device, for example, the device information of each device is unique and is stored separately as private point location description information.

[0099] By dividing the configured device point location description information into public point location description information and private point location description information, storage space can be saved, all devices can jointly maintain a copy of the public point location description information, and when the configured device point location description is updated, only the private point location description information in the configured device point location description information is updated according to the private point location description information in the point location description information of the device to be accessed. The updating efficiency is improved, and resource storage space is saved.

[0100] In another implementable manner, the currently configured device point location description information of the target system is not divided into public and private parts, that is, each device corresponds to a DSL file and is stored separately. It is similar to that a plurality of subfiles are stored under a folder, and each subfile corresponds to a DSL file of a device. The DSL file of each device is maintained separately.

[0101] In this way, when the currently configured device point location description information of the target system is updated according to the point location description information of the device to be accessed, the point location description information (DSL file) of the device to be accessed can be added to the configured device point location description information as a separate file.

[0102] For example, the device point position description information currently configured by the target system is stored in a preset folder, the folder contains 5 subfolders, and the 5 subfolders are respectively DSL files corresponding to 5 accessed devices. The update of the configured device point position description information can be writing the DSL file of the to-be-accessed device into the preset folder, and then the preset folder contains 6 subfolders.

[0103] In this way, when there is a to-be-accessed device, a DSL file is added to the device point position description information currently configured by the target system. When some configuration information of the devices is the same, some repeated contents exist in the DSL files of the devices. However, this does not affect the implementation of the scheme.

[0104] Optionally, in step S103, generating the target gateway execution code according to the updated device point position description information can include: performing code compilation according to the updated point position description information and a gateway basic code to generate the target gateway execution code.

[0105] In some embodiments, the target gateway execution code can be compiled and generated according to the updated point position description information and the gateway basic code. The gateway basic code can refer to a code generation script, for example, a gateway program. The updated point position description information and the gateway basic code are collectively subjected to code compilation to generate the target gateway execution code.

[0106] By generating the target gateway execution code, the related configuration information of the to-be-accessed device can be compatible with the related configuration information of the accessed device.

[0107] Figure 3 Another device access method provided by the embodiment of the present application is provided. Optionally, in step S103, collecting data of the devices accessed to the target system can include:

[0108] S301, collecting data of each accessed device according to a data collection strategy of each accessed device.

[0109] Optionally, based on the generated target gateway execution code, running the target gateway execution code can access the to-be-accessed device to the target system, and perform data collection, processing, packaging, uploading and other operations on each device accessed to the target system according to the DSL execution designed in the target gateway code.

[0110] Optionally, the data of each accessed device can be collected according to the data collection strategy of the accessed device, the set collection frequency, collection rate and collection content.

[0111] S302, package the collected data of each device that has accessed the target system according to the data packaging strategy of each device that has accessed the target system.

[0112] According to the data packaging strategy of the accessed device, the collected data of each accessed device is packaged into a specified data format.

[0113] S303, report the packaged data of each device that has accessed the target system to the server for display according to the data reporting strategy of each device that has accessed the target system.

[0114] According to the data reporting strategy of the accessed device, the packaged data of each accessed device is uploaded to the server for storage and display.

[0115] In summary, the device access method provided in the embodiment includes: obtaining point table information of a current device to be accessed, and generating point position description information of the device to be accessed according to the point table information, the point position description information including relevant configuration information of the device to be accessed accessing a target system; updating device point position description information currently configured by the target system according to the point position description information of the device to be accessed, to obtain updated device point position description information; generating target gateway execution code according to the updated device point position description information and running the target gateway execution code, to access the target system by the current device to be accessed, and to collect data of the device accessing the target system. When a new device needs to access the system, the point table information of the device to be accessed can be obtained, and the point position description information of the device to be accessed is converted and generated, so that the device point position description information currently configured by the system can be quickly updated based on the point position description information of the device to be accessed.
