Manufacturers need to integrate the correlation of hardware cost, equipment stability, program debugging, burning, setting, equipment batch production test, monitoring and delivery. Therefore, the cycle time is long, and the modification and burning of the program, the change of the storage mode, and the like may prolong the lead time. For this reason, once the protocol is qualitative, it can be modified within a small range, but it is difficult and not willing to make too many changes. If the platform side is compromised in the existing manner for device stability, each vendor develops a specific module for the vendor's agreement.
When multiple protocols are accessed to the same platform, most platforms adopt an access mode that one protocol corresponds to one special module, and the access of protocol manufacturers is met. The access mode needs each manufacturer to provide a detailed protocol of the manufacturer in advance, and the platform manufacturer needs to take the protocol in advance and independently encapsulate the module, so that the problem of access of equipment of the manufacturer can be solved.
As more and more protocol manufacturers exist, more and more special modules exist in the manufacturers. Therefore, more and more proprietary modules are loaded on the platform, which causes the straight line decline of the stability, performance and the like of the system, and seriously wastes the convenience of hardware resources and business logic.
Therefore, there are at least the following three problems in the related art in summary.
1. The manufacturers have a plurality of units, each of which has a self-defined protocol, and the standards are difficult to unify;
2. terminal equipment changes a unified protocol, so that the equipment is poor in qualitative and stability, and the debugging and testing period is prolonged;
3. a special module is independently developed for each manufacturer, the number of the special modules is more and more along with the access of the manufacturers, and the complexity and the stability are reduced.

Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
(1) In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
(2) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
(3) The internet of things equipment, for example, the intelligent equipment of various sensors, such as temperature sensor, humidity sensor, pressure sensor, etc. can report the equipment of detected data on a network.
(4) The shell adding parameters can be adopted to add the shell to the own protocol data packet of the manufacturer in the embodiment of the application, so that the management platform of the Internet of things equipment can analyze the protocol data packet of the manufacturer based on the shell adding parameters.

(6) A server serving the terminal, the contents of the service such as providing resources to the terminal, storing terminal data; the server is corresponding to the application program installed on the terminal and is matched with the application program on the terminal to run. 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 an APP (Application) of a software class, or may refer to a client. The system is provided with a visual display interface and can interact with a user; is corresponding to the server, and provides local service for the client. For software applications, except some applications that are only run locally, the software applications are generally installed on a common client terminal and need to be run in cooperation with a server terminal. After the development of the internet, more common application programs include short video applications, email clients for receiving and sending emails, and clients for instant messaging, for example. For such applications, a corresponding server and a corresponding service program are required in the network to provide corresponding services, such as database services, configuration parameter services, and the like, 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 a manufacturer side, and the manufacturer can realize the configuration of the shell adding parameters and the analysis files based on the interaction of the terminal equipment and the server.
In the related art, as more and more protocol manufacturers exist, more and more special modules exist in the manufacturers. Therefore, more and more proprietary modules are loaded on the platform, which causes the straight line decline of the stability, performance and the like of the system, and seriously wastes the convenience of hardware resources and business logic.
In view of this, an embodiment of the present application provides an access method for a multi-protocol device. In the embodiment of the application, a manufacturer can customize a shell adding parameter for adding a shell to the protocol data packet, so that the management platform can analyze the protocol data packet of the manufacturer and execute corresponding operation based on the shell adding parameter. When the protocol data package analysis method is implemented, the shell adding parameters are used for indicating a verification method and an instruction analysis method of the protocol data package, and each manufacturer can uniformly configure the shell adding parameters for the protocol data package according to the requirements of the management platform, so that the management platform can finish analysis of the protocol data packages of different manufacturers based on the shell adding parameters. Therefore, the management platform does not need to develop a special module for the individualized configuration of each manufacturer, the system stability and the performance of the management platform are improved, and hardware resources and service logic can be facilitated. In addition, the two-way flexible communication between the management platform and the equipment is realized for the equipment of the Internet of things based on the flexible packaging instruction of the packaging method.
Fig. 1 is a schematic view of an application scenario of a multi-protocol device access method according to an embodiment of the present application. The application scenario includes 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 and a humidity sensor. The server 102 may be a server, a server cluster composed of several 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 basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, middleware service, a domain name service, a security service, a CDN, a big data and artificial intelligence platform, and the like.
The terminal device 103 may be a device capable of displaying a user operation interface and interacting with a user, such as a mobile phone, a tablet computer, a desktop computer, and a smart television. For example, a manufacturer may access the server 102 through the terminal device 103, complete configuration operations on the shell adding parameters and the parsing file in the user material interface of the terminal device 103, and synchronize the configuration results to the server 102 for storage. Therefore, when the internet of things equipment sends the protocol data packet to the server 102, the protocol data packet can be shelled based on the shelling parameter, after the server 102 receives the shelled protocol data packet, the shelling operation can be performed on the protocol data packet to obtain the shelling parameter, then the protocol data packet of the scene is analyzed based on the parsing file corresponding to the obtained shelling parameter by the manufacturer, and therefore the corresponding operation of the protocol data packet is executed.
Of course, the method provided in the embodiment of the present application is not limited to the application scenario shown in fig. 1, and may also 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 in the following method embodiments, and will not be described in detail herein.
To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or figures, more or less operation steps may be included in the method based on the conventional or non-inventive labor. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application.
When multiple protocols are accessed to the same platform, most of the platforms adopt an access mode of one protocol and one module, so that the access of protocol manufacturers is met, the access mode needs each manufacturer to provide a detailed protocol of the manufacturer in advance, the platform manufacturers need to take the protocol in advance, and the modules are independently packaged, so that the problem of access of equipment of the manufacturers can be solved. In the embodiment of the application, the protocol mode is adopted to allow equipment to access a manufacturer, the analysis of the protocol is automatically realized by adopting a user interface operation and dynamic programming mode, and each manufacturer is not required to provide a module. Referring to fig. 2, a flowchart of a multi-protocol device access method provided in an embodiment of the present application is schematically illustrated, 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 adding parameters of the internet of things device are acquired.
As described above, the shell adding parameter is used to add a shell to a protocol data packet of the internet of things device and then send the protocol data packet to a management platform, and the shell adding parameter is used to indicate a verification method, an instruction parsing method and an instruction encapsulation method of the protocol data packet.
In some possible embodiments, the shelling parameters include: a message synchronization word and a verification method identifier 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 equipment, and an analysis method and an instruction encapsulation method of the protocol data packet are configured in the analysis file;
the verification method identifier is used for indicating the management platform to perform verification operation on the protocol data packet by adopting a verification method corresponding to the verification method identifier.
The device manufacturer may refer to a manufacturer of a plurality of devices to be connected to the device management platform, and each manufacturer has a different manufacturer agreement with the management platform. In the embodiment of the application, the management platform has fixed positions of factory synchronization words (namely message synchronization words) and message instruction words, and provides a uniform data accuracy verification method and a uniform data accuracy verification function. Therefore, a uniform shell configuration interface can be provided for configuring shell parameters for each scene. As shown in fig. 3, an exemplary schematic of an interface is configured for a housing. In fig. 3, a manufacturer can edit its own message synchronization word, and for the management platform, the message synchronization word can only globally distinguish different manufacturers or different devices. The "details" in FIG. 3 may facilitate the manufacturer in viewing the configured shelling parameters. The "delete" in FIG. 3 may facilitate the manufacturer to delete obsolete shelling parameters, and the edit in FIG. 3 may allow the manufacturer to configure new shelling parameters or modify existing shelling parameters. The message sync word may be queried in fig. 3, or a new message sync word may be created using the "create" control.
Therefore, the application discloses a multi-protocol equipment access method, which can enable a manufacturer to realize multi-protocol access by combining the simplest interface operation with a data storage mode and utilizing an automatic dynamic programming mode, and allows protocol flexibility and diversity.
In some embodiments, not only the message sync word may be used as an index of the parsed file, but the shell adding parameter in this embodiment further includes: the unique equipment identification of the Internet of things equipment, the unique equipment identification and the message synchronization word, and an index value of the analysis model are established by a user.
One way to configure the parse file may be implemented as:
in step a1, displaying a parse-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 template comprises: an operation item for configuring an instruction type, an operation item for configuring an instruction word of the instruction type, and an operation item for configuring a byte position and an attribute value of the instruction word;
in step a2, the parse file is generated based on a user operation with respect to the parse-file configuration interface.
Fig. 4a is a schematic diagram of a user interface for configuring a parsing file. In fig. 4a, the implementation instruction type, the instruction word, the position of the key parameter byte, and the attribute value are labeled, and the management platform performs data storage on the information. The message synchronization word is used as an index and written into a database according to a fixed format template (analysis template). As shown in fig. 4b, a plurality of sets of parsing templates may be configured in the parsing file of each scene through a user interface configured with the parsing file, in this embodiment, each instruction type corresponds to one set of parsing templates.
Assuming that the user clicks the "edit" control in FIG. 3, a schematic view of the user interface entering the power-up and power-down command configuration is shown in FIG. 4 a. In fig. 4a message sync word (i.e. a vendor sync word) 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 the instruction type is configured as a type for powering on and powering off in fig. 4 a. The instruction word of the instruction type is used to identify the instruction type, and as shown in fig. 4a, the instruction word 01a identifies the configured instruction type as power-up and power-down. The overall length of fig. 4a is configured to have 12 bytes for the power-up/power-down command. The data content is an attribute value of the instruction word, and in fig. 4a, an attribute value of 01 indicates power-on and an attribute value of 00 indicates power-off. The length behind the data content is used for indicating the position of the instruction word, namely the power-on starts to analyze in the second byte of the whole length, the power-off starts to analyze in the second byte of the 12 bytes of the whole length, and the power-on and power-off belong to mutual exclusion operation, so that only one state is reported each time, and no conflict exists.
Similarly, fig. 4b is a schematic diagram of a user interface for configuring a set of parsing templates with an instruction type of "message reporting". In fig. 4b, the message report instruction word is 12, the total length of the message is 50 bytes, and the data content is used as the attribute value of the instruction word, including a port number, where the port number is used to indicate from which port the reported message is obtained, 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, it is used to indicate that the valid data content reported by the message starts from the 22 th byte. Another attribute value in fig. 4b is a start time, which is used to indicate a specific reporting time of the message, and the start time can be parsed from the 30 th byte of the received protocol data packet.
In other embodiments, as shown in FIG. 4b, a plus control may be employed to add properties to the instruction word. In implementation, the user interface contents included in different instruction types may be different, and the typesetting manner may also be different, and the configuration of the parsing file is convenient.
As shown in fig. 4b, the instruction type can also be added as a heartbeat message response, the manufacturer instruction word is 43, the overall length of the message is 32 bytes, and the message processing specific result attribute starts from the 11 th byte and is 1 byte in length. The resolution of the port number attribute starts from byte 12 and is 1 byte in length. The length shown behind the attribute is the initial byte of the attribute which begins to be analyzed in the whole message, and the specific attribute length is obtained by subtracting the initial bytes of the adjacent attributes in sequence according to the adding sequence. Of course, in other embodiments, the port number and the length of the message processing result may be configured as configurable items.
Therefore, the interface scene can be configured based on the analysis file, the analysis text can be defined by the user and stored in the management platform, and then the management platform can analyze the protocol data packet of the corresponding scene based on the shell adding parameter and the analysis file.

in step 501, a shell-added data packet sent by the internet of things device is received, where the shell-added data packet is sent by the internet of things device after a protocol data packet of the internet of things device is shell-added based on a pre-configured shell-added parameter, and the shell-added parameter is used for indicating a verification method and an instruction analysis method of the protocol data packet.

Parsing the protocol packet may be performed, for example, based on an underlying device power-up/down message. The template is analyzed as follows:
the parsing file of the scene is indexed based on the message sync word ohgy, and the upper and lower point-related parsing templates in the parsing file are as shown in the above example. If the position of the protocol data packet command word is analyzed to be 01 based on the analysis template, the power-on command is shown, and if the position of the protocol data packet command word is analyzed to be 00, the power-off command is shown. Whereby a corresponding power-up or power-down operation can be performed.
In some embodiments, after the parsing template is not found, the application may further fill an abnormal parsing log, and perform protocol parsing reminding according to the abnormal parsing log.
