Technical Field

[0002] In recent years, various types of equipment have developed rapidly and are diverse. In a large-scale usage scenario, there may be a large number of heterogeneous devices that need to be accessed, centrally controlled, and resource managed. To achieve the access of a large number of heterogeneous devices, two problems need to be solved at the same time: one is the physical layer communication. Due to the inconsistency of communication equipment, methods, and interfaces used by different devices, it is difficult to achieve interconnection at the physical layer; the other is the information layer interaction. Due to the inconsistency of information interaction formats and contents followed by different electromagnetic devices, it is difficult to achieve organic integration and sharing of data at the information layer.

[0003] The traditional way to achieve integrated access is to transform existing equipment according to unified physical interfaces and communication protocols.

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Reference Figure 1 , shows a flowchart of a method for data transmission of heterogeneous devices of the present application, which can be applied to electronic devices, wherein the method can specifically include the following steps:

[0054] S101, obtaining a first data message sent by a heterogeneous device through a first communication protocol;

[0055] S102, determining a second communication protocol corresponding to the first communication protocol according to a pre-established protocol adaptation model; wherein the pre-established protocol adaptation model includes a correspondence between communication protocols of different devices;

[0056] S103: Convert the first data message into a second data message corresponding to the second communication protocol.

[0057] Another embodiment of the present application further supplements the data transmission method for heterogeneous devices provided in the above embodiment.

[0058] Optionally, the pre-established protocol adaptation model is obtained by:

[0059] Based on the protocol adaptation algorithm modeled by finite state machine, the protocol data conversion automaton corresponding to different devices is constructed according to the communication protocol interface rules, and a set of inter-process communication APIs are provided to the communicating parties.

[0060] Optionally, the method further comprises:

[0061] Generate a first protocol model tree according to a third communication protocol at the input end;

[0062] Generate a second protocol model tree according to the fourth communication protocol of the output end;

[0063] According to the first protocol model tree and the second protocol model tree, a conversion relationship between data types and operation functions is generated to obtain a protocol adaptation model.

[0064] Principle of protocol adapter software: Protocol adapter software mainly uses protocol adapter technology based on finite state machine modeling, builds corresponding protocol data conversion automata according to communication protocol interface rules, and provides a set of inter-process communication APIs to both parties for use. Without changing the software of both parties, it completes real-time protocol conversion and realizes interconnection and information sharing between the two parties. The basic theoretical basis of protocol adapter software is the finite state machine model. Finite state machine (FSM) is a mathematical model that represents a finite number of states and behaviors such as transitions and actions between these states. The basic concepts in finite state machines include state and action. The state stores information about the past, which reflects the input changes from the beginning of the system to the present moment; the action is a description of the activities to be performed at a given moment.

[0065] The logical structure of the communication protocol in the embodiment of the present application conforms to the tree structure. For this reason, all communication protocols can be abstracted into a corresponding tree semantic model - protocol model tree (PMT). PMT is a state machine, and a node of PMT is a state of the state machine. PMT is divided into input tree (IPWT) and output tree (OPWT) according to the flow direction of its data.

[0066] In protocol adaptation, when PMT describes the protocol of the input end, it is the input tree; when PMT describes the protocol of the output end, it is the output tree. The purpose of protocol adaptation is to convert the data elements of the input tree into the data elements of the output tree. A set of formulas including data types and operation functions y=f(x…) are defined to describe the conversion relationship. This set of formulas connects the two trees in a directed graph, such as Figure 2 shown.

[0067] Optionally, the method further comprises:

[0068] After generating the second data message corresponding to the second communication protocol, determining a preset application protocol driver corresponding to the second communication protocol; and using the application protocol driver to send the second data message.

[0069] Protocol adapter software architecture Figure 3As shown, it includes four components: model manager, device driver, application protocol adapter server and I / O communication module. The model manager establishes corresponding protocol adaptation models for the communication protocols of different devices, builds a protocol model tree by analyzing the composition of the protocol, establishes a mapping relationship between the protocols of different devices, and compiles and generates corresponding device drivers. The device driver is a dynamic link library generated for different complex devices. It identifies information that conforms to the device communication protocol, drives the application protocol adapter server to communicate with the other end of the communication device, thereby completing the seamless integration between the two device systems. The application protocol adapter server is an independent executable program that completes the mutual conversion of the communication protocols of the two devices by calling the device driver, thereby realizing the interconnection between the two. The I / O communication module completes the direct communication between the protocol adapter software and the device.

[0070] Optionally, the method further comprises:

[0071] receiving a third message sent by the control device, where the third message includes a TCP message, a UDP message, an HTTP message, or a serial communication protocol message;

[0072] The third message is converted into structured data according to a pre-established protocol adaptation model, or the structured data is converted into the third message according to a pre-established protocol adaptation model.

[0073] Heterogeneous device sensing and control technology supports the encapsulation and transmission of TCP, UDP, HTTP, serial communication and other protocols, and has two-way protocol conversion capabilities, one is to convert the collected original message into structured data according to the protocol definition, and the other is to convert the structured data into device push messages according to the protocol definition. It also manages and maintains the data channel.

[0074] Optionally, the method further comprises:

[0075] According to the different openness levels of heterogeneous devices, the corresponding access mode is determined, and the access mode at least includes a command mode, a task mode or a plug-in mode.

[0076] like Figure 4 As shown, the tool provided in the embodiment of the present application provides three modes of device access: command mode, task mode, and plug-in mode. The appropriate access mode is adopted according to the openness of the device, including:

[0077] Command mode: Based on this tool, the protocol access with heterogeneous devices is completed, and the command-level integrated access between the tool and the device is realized, and the behavior of the device is directly sensed and controlled. The command mode is the main mode of device access.

[0078] Task mode: For semi-open devices, when instruction-level integration cannot be achieved, the task docking mode is adopted to complete the task docking of the device through the open access of this system.

[0079] Plug-in mode: For closed devices or devices that cannot be connected, the plug-in mode is used to sense the location of the plug-in device instead of the real-time location of the device.

[0080] The present application embodiment formulates a set of standardized processes for heterogeneous device access to standardize the process of device access, debugging, and application. Figure 5 As shown, specifically including:

[0081] Protocol configuration: Based on this system, the device's protocol structure, collection protocol, and push protocol are solidified in the system;

[0082] Network configuration: Based on this system, the connection channels and data channels of the equipment are solidified in the system;

[0083] Docking development: Customize the secondary development interface based on the protocol of this system, conduct secondary development according to the protocol specificity and business requirements of the equipment, and complete the protocol compatibility work;

[0084] Joint debugging test: Test the perception and control capabilities of the device based on the test environment to verify the normality and stability of all interfaces and instructions;

[0085] Version release: Based on this system, the integrated device protocols and configurations are released to the formal environment and switched to the formal usage scenario.

[0086] Personalized protocol customization: Open API is the open service capability of this software platform, which supports developers to customize the protocol and connect data with upstream systems based on the basic capabilities of the platform. It supports two application layer protocols, HTTP and WebSocket, and supports SDK integration of Java language for secondary development. For some simple algorithms, it supports online dynamic scripting language.

[0087] For the control instructions of the equipment, the platform will provide the upper-layer business applications with http-Rest interfaces. For the collection instructions of the equipment, the platform will provide the upper-layer business applications with web socket data push channels to achieve real-time data arrival. The integrated access technology based on protocol adaptation is adopted to achieve the communication between the physical layer and information layer of different devices through "integrated access equipment + protocol adaptation software". The advantages of this method are:

[0088] First, the equipment does not need to be changed. Protocol conversion can be achieved by simply establishing a mapping model of the communication protocol between devices through protocol adaptation software;

[0089] Second, traditional protocol conversion work must be completed by programmers through programming, while users of protocol adaptation software only need to establish a protocol conversion model through a graphical interface, and the software will automatically generate a program in the background based on the model established by the user;

[0090] Third, the protocol conversion model has good inheritability and portability. For newly connected devices, as long as they comply with known protocol standards or are similar to known communication protocols, the protocol conversion of the newly connected devices can be completed by modifying the existing protocol conversion model.

[0091] An embodiment of the present invention provides a data transmission method for heterogeneous devices, including: obtaining a first data message sent by the heterogeneous device through a first communication protocol; determining a second communication protocol corresponding to the first communication protocol according to a pre-established protocol adaptation model; wherein the pre-established protocol adaptation model includes a correspondence between communication protocols of different devices; converting the first data message into a second data message corresponding to the second communication protocol can solve the problem of temporary access of a large number of heterogeneous devices and can quickly realize control and resource management of the access devices.
