(6) The server is used for serving the terminal, and the content of the service provides resources for the terminal and stores the terminal data; the server corresponds to the application program installed on the terminal and operates in cooperation with the application program on the terminal. The server in the embodiment of the application can be realized as a management platform of the Internet of things equipment.
(7) The terminal device may refer to APP (Application) of a software class or a client. The system has a visual display interface, and can interact with a user; corresponding to the server, providing local service for clients. Applications for software classes, except some applications that only run locally, are typically installed on a common client terminal, and need to run in conjunction with a server. After the development of the internet, more commonly used application programs include, for example, short video applications, email clients when receiving email, and clients for instant messaging. For this type of application program, there is a need to have a corresponding server and service program in the network to provide a corresponding service, such as a database service, a configuration parameter service, etc., so that a specific communication connection needs to be established between the client terminal and the server terminal to ensure the normal operation of the application program. In the embodiment of the application, the terminal equipment can be arranged at the manufacturer side, and the manufacturer realizes the configuration of the shelled parameters and the analysis files based on the interaction of the terminal equipment and the server.
In the related art, as protocol manufacturers are more and more, the special modules of the manufacturers are more and more. Thus, more and more proprietary modules are loaded on the platform, which causes the linear reduction of the stability, performance and the like of the system, and seriously wastes hardware resources and facilitates business logic.
In view of this, the embodiment of the application provides an access method of a multi-protocol device. In the embodiment of the application, a manufacturer can self-define the shell adding parameters for adding the shell to the protocol data packet, so that the management platform can analyze the protocol data packet of the manufacturer and execute corresponding operations based on the shell adding parameters. When the method is implemented, the shell parameters are used for indicating the verification method and the instruction analysis method of the protocol data packet, and each manufacturer can uniformly configure the shell parameters for the own protocol data packet according to the requirements of the management platform so that the management platform can complete the analysis of the protocol data packets of different manufacturers based on the shell parameters. Therefore, the management platform does not need to develop a special module for personalized configuration of each manufacturer, the system stability and performance of the management platform are improved, and hardware resources and business logic can be facilitated. In addition, the two-way flexible communication of the management platform and the equipment is realized for the Internet of things equipment based on the flexible packaging instruction of the packaging method.
Referring to fig. 1, an application scenario of a multi-protocol device access method according to an embodiment of the present application is shown. The application scene comprises a plurality of internet of things devices 101 (including internet of things device 101-1, internet of things device 101-2 and … … internet of things device 101-n), a server 102 (i.e. a management platform) and a terminal device 103. The internet of things equipment 101 and the server 102 are connected through a wireless or wired network, and the internet of things equipment 101 comprises various internet of things equipment such as a temperature sensor, a pressure sensor, a humidity sensor and the like. Server 102 may be a server, a server cluster formed by a plurality of servers, or a cloud computing center. The server 102 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, basic cloud computing services such as big data and artificial intelligence platforms, and the like.
The terminal device 103 may be a device capable of displaying a user operation interface, such as a mobile phone, a tablet computer, a desktop computer, a smart television, and interacting with a user. For example, a manufacturer can access the server 102 through the terminal device 103, complete the configuration operation of the shell adding parameters and the analysis files in the user material interface of the terminal device 103, and synchronize the configuration result to the server 102 for storage. Therefore, when the internet of things device sends the protocol data packet to the server 102, the protocol data packet can be shelled based on the shelled parameter, after the server 102 receives the shelled protocol data packet, the shelled parameter can be obtained by shelling the protocol data packet, and then the protocol data packet of the scene is parsed based on the shelled parameter to obtain the parsed file corresponding to the manufacturer, so that the corresponding operation of the protocol data packet is executed.
Of course, the method provided by the embodiment of the present application is not limited to the application scenario shown in fig. 1, but may be used in other possible application scenarios, and the embodiment of the present application is not limited. The functions that can be implemented by each device in the application scenario shown in fig. 1 will be described together in the following method embodiments, which are not described in detail herein.
In order to further explain the technical solution provided by the embodiments of the present application, the following details are described with reference to the accompanying drawings and the detailed description. Although embodiments of the present application provide the method operational steps shown in the following embodiments or figures, more or fewer operational steps may be included in the method, either on a routine or non-inventive basis. In steps where there is logically no necessary causal relationship, the execution order of the steps is not limited to the execution order provided by the embodiments of the present application.
When the multiple protocols are accessed to the same platform, most of the platforms adopt an access mode of one protocol and one module, so that access of protocol manufacturers is met, each manufacturer is required to provide a detailed protocol of the manufacturer in advance, the platform manufacturer is required to take the protocol in advance, and the modules are independently packaged, so that the problem of access of manufacturer equipment can be solved. In the embodiment of the application, the adopted protocol mode is to allow the equipment to be accessed to manufacturers, and the analysis of the protocol is automatically realized by adopting a user interface operation and a dynamic programming mode without providing a module for each manufacturer. Referring to fig. 2, a flowchart of a multi-protocol device access method is provided in an embodiment of the present application, where the method is applied to a terminal device, and includes the following steps:
In step 201, a shell configuration interface is displayed;
In step 202, in response to a user operation on the shell configuration interface, shell parameters of the internet of things device are obtained.
As stated above, the shell adding parameter is used for adding a shell to the protocol data packet of the internet of things device and then sending the protocol data packet to the management platform, and the shell adding parameter is used for indicating a verification method, an instruction analysis method and an instruction encapsulation method of the protocol data packet.
In some possible embodiments, the capping parameters include: message synchronization word, verification method identification of the protocol data packet;
The message synchronization word is used for indicating the management platform to acquire an analysis file of the internet of things device, and the analysis file is configured with an analysis method and an instruction encapsulation method of the protocol data packet;
The verification method identifier is used for indicating the management platform to carry out verification operation on the protocol data packet by adopting a verification method corresponding to the verification method identifier.
The device manufacturer may refer to manufacturers of various devices to be accessed to the device management platform, where each manufacturer has different manufacturer protocols with the management platform. In the embodiment of the application, the management platform has fixed manufacturer synchronous words (namely message synchronous words) and message instruction word positions, and provides a unified data accuracy checking method and checking function. Therefore, a unified crust configuration interface can be provided for configuring the crust parameters for each scene. An exemplary schematic of a housing configuration interface is shown in fig. 3. In fig. 3, the manufacturer may edit its own message synchronization word, and for the management platform, the message synchronization word may be globally unique and able to distinguish between different manufacturers or different devices. The details in fig. 3 may facilitate the manufacturer's view of the configured shell parameters. The "delete" in fig. 3 may facilitate the manufacturer to delete the obsolete shelled parameters, and the edit in fig. 3 may allow the manufacturer to configure new shelled parameters or to modify existing shelled parameters. In fig. 3, the message syncword may be queried, or a new message syncword may be created using a "create" control.
It can be seen that the application discloses a multi-protocol device access method, which can enable manufacturers to realize multi-protocol access by combining the simplest interface operation with a data storage mode and utilizing an automatic dynamic programming mode, thereby allowing protocol flexibility and diversity.
In some embodiments, not only can the message synchronization word be used as an index for parsing the file, but also the shell adding parameters in the embodiment of the application include: and constructing an index value of the analysis model by a user according to the equipment unique identifier of the equipment of the Internet of things, the equipment unique identifier and the message synchronization word.
One way to configure a parse file may be implemented as:
In step A1, displaying an analysis file configuration interface; the analysis file configuration interface is used for configuring at least one set of instruction analysis templates, and each set of instruction analysis templates comprises: an operation item for configuring an instruction type, an operation item for configuring an instruction word of the instruction type, an operation item for configuring a byte position and an attribute value of the instruction word;
in step A2, the parsed file is generated based on a user operation for the parsed-file configuration interface.
FIG. 4a is a schematic diagram of a user interface for configuring a resolution file. In fig. 4a, the implementation instruction type, the instruction word, the position where the instruction word is located, the key parameter byte position and the attribute value are marked, and the management platform stores the information in data. And writing the message synchronization word serving as an index into a database according to a fixed format template (analysis template). As shown in fig. 4b, multiple sets of parsing templates may be configured in the parsing file of each scene through a user interface configured with the parsing file, and in the embodiment of the present application, each instruction type corresponds to one set of parsing templates.
Assuming the user clicks the "edit" control in fig. 3, a user interface diagram for entering the power-on and power-off instruction configuration is shown in fig. 4a. In fig. 4a, a message syncword (i.e. a vendor syncword) is shown, the vendor name representing the vendor providing the device. In the interface shown in fig. 4a, the operation item for configuring the instruction type is "instruction type", and in fig. 4a, the instruction type is configured for powering up and down. The instruction word of the instruction type is used to identify the instruction type, such as instruction word 01a in fig. 4a identifying that the configured instruction type is power up and power down. The overall length of fig. 4a is used to configure the number of bytes occupied by the power-up and power-down instruction to be 12 bytes. The data content is the attribute value of the instruction word, in fig. 4a, the attribute value 01 indicates power-up and 00 indicates power-down. The length after the data content is used for indicating the position of the instruction word, namely, the second byte in the whole length starts to be analyzed when the power-on and the power-off start to be analyzed when the second byte in the 12 bytes in the whole length, and the power-on and the power-off belong to mutual exclusion operation, so that only one state can be reported at each time, and no conflict exists.
Similarly, FIG. 4b is a schematic diagram of a user interface for configuring a set of parsing templates for an instruction type "message report". In fig. 4b, the message reporting instruction word is 12, the total length of the message is 50 bytes, the data content is an attribute value of the instruction word, and the attribute value includes a port number, where the port number is used to indicate from which port the reported message is acquired, and a length after the port number is used to indicate from which byte the content of the message starts, for example, in fig. 4b, the valid data content used to indicate that the message reporting starts from the 22 th byte. Another attribute value in fig. 4b is a start time, which indicates a specific reporting time of the message, and the start time may be parsed from the 30 th byte of the received protocol data packet.
In other embodiments, as shown in FIG. 4b, the properties of the instruction word may be added using a plus control. In implementation, the content of the user interface included in different instruction types may be different, and the typesetting manner may also be different, so long as the configuration of the analysis file can be conveniently applied to the embodiment of the present application.
As shown in fig. 4b, the instruction type may be further added to be a heartbeat message response, the manufacturer instruction word is 43, the whole length of the message is 32 bytes, and the specific result attribute of the message processing is from 11 th byte to 1 byte. The port number attribute is parsed from the 12 th byte, and the length is 1 byte. The length displayed behind the attribute is the initial byte of the attribute which starts to be analyzed in the whole message, and the specific attribute length sequentially subtracts the initial bytes of the adjacent attributes according to the adding sequence to obtain the specific length. Of course, in other embodiments, the port number and the length of the message processing result may be configured as configurable items.
