The data interaction method and the terminal of the distributed gateway are suitable for realizing scene linkage and automatic control across the gateways under the multi-gateway, and are described by specific embodiments below:
example 1
Referring to fig. 1, a data interaction method of a distributed gateway includes the steps of:
s1, splitting a main gateway into a plurality of process components according to business logic of the gateway.
Specifically, the main gateway is split into a daemon process, a gateway process, a device process, a network process or a plurality of process components in the internet of things process according to the business logic of the gateway.
In this embodiment, the gateway needs to have three basic processes, namely a daemon process, a network process and an equipment process, and each process is disassembled according to service logic and performs message interaction through standard Socket communication;
the equipment process is responsible for accessing the sub-equipment, and the sub-equipment access standard of external packaging standard can support the access of equipment with different communication media, such as zigbee, ble and the like;
the internet of things process is used for docking with platform services, and interfaces of external packaging standards can dock different internet of things platforms, so that docking of different ecological platforms can be quickly adapted;
the gateway process is used for main business logic processing of the gateway, and the gateway running the gateway process is the main gateway.
Thus, in this embodiment, the primary gateway may be split into a daemon process, a gateway process, a device process, and a network process, and in other embodiments, the primary gateway may be split into a daemon process, a gateway process, a device process, a network process, and an internet of things process.
S2, building a message bus, and accessing a plurality of process components in the main gateway into the message bus.
In this embodiment, a message bus based on Socket communication is set up, a soft bus with hardware platform independence is realized, and a plurality of process components in a main gateway perform data interaction based on Socket communication through the message bus.
Referring to fig. 3, a daemon process, an internet of things process, a gateway process and a device process are all connected to a message bus, so as to complete the construction of a single gateway architecture.
Meanwhile, the premise of interconnection of all process components is that: a unified product model is used for establishing a standard product database; a unified network communication Socket interface provides a standard subscription/notification mechanism; standard service interfaces and callback interfaces are provided between the components.
S3, accessing the process component of the slave gateway into the message bus, and carrying out data interaction in the slave gateway.
The process components of the slave gateway comprise a daemon process, a device process and a network process, wherein the daemon process of the slave gateway is in communication connection with the network process and the device process, and the device process and the network process of the slave gateway are directly accessed to a message bus.
Referring to fig. 4, the slave gateway is not provided with a gateway process and is accessed as a separate device process. Within a local area network, each device process represents access to a subsystem of devices. Therefore, as long as the construction of the architecture of the single gateway is completed, namely the normal operation environment of the master gateway, other slave gateways can be accessed through the message bus.
In addition, in this embodiment, the master gateway and the slave gateway belong to the same network, and when the local area network configures the network topology, the master gateway can be manually allocated, or one gateway can be determined to be the master gateway in an election mode, and the other gateways are slave gateways.
Specifically, determining the primary gateway by adopting an election mode specifically includes: and monitoring the running condition of the master gateway, and if the master gateway has faults, selecting a new master gateway according to the configuration information of the slave gateway. In this embodiment, a method of a type distributed microservice architecture is adopted, and an election strategy, such as a Raft algorithm, is adopted in the same local area network, so that only one gateway is ensured to be a master gateway at the same time, and distributed synchronous storage of data is realized. The newly elected master gateway can set its gateway process through hardware configuration.
Example two
Referring to fig. 2, a data interaction terminal 1 of a distributed gateway includes a memory 2, a processor 3, and a computer program stored in the memory 2 and executable on the processor 3, wherein the processor 3 implements the steps of the data interaction method of the distributed gateway according to the first embodiment when executing the computer program.
In summary, according to the data interaction method and terminal for the distributed gateway provided by the invention, the main gateway is split into the daemon process, the internet of things process, the gateway process, the equipment process and the network process according to the service logic, each process component is accessed to the message bus, then the network process and the equipment process of the slave gateway are also accessed to the message bus, and the data interaction of different processes in each gateway is realized through the network process and the equipment process accessed by each gateway. In this way, by disassembling the gateway and accessing all disassembled components to the same message bus, the diversity of equipment access can be improved, and scene linkage and automation control can be realized through cross-gateway data interaction. And meanwhile, a new main gateway is elected when the main gateway fails in a monitoring and electing mode, so that the reliability of the distributed gateway is ensured.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent changes made by the specification and drawings of the present invention, or direct or indirect application in the relevant art, are included in the scope of the present invention.
