Description

Unified management method and system for heterogeneous Internet of things equipment in passive optical network Technical Field The invention relates to the technical field of optical network communication and Internet of things, in particular to a unified management method and system for heterogeneous Internet of things equipment in a passive optical network. Background In modern communication networks, fiber To The Home (FTTH) based on Passive Optical Network (PON) technology has become a mainstream solution for providing high-speed broadband access. On the user side of the PON network, a Home Gateway Unit (HGU) is a core device, and integrates various functions such as an Optical Network Terminal (ONT), a router, and a wireless access point (Wi-Fi), which are an entrance and a hub of the entire home network. Meanwhile, along with the rapid development of the internet of things, the intelligent home field presents remarkable characteristics of equipment diversification and communication protocol diversification. Currently, a mainstream intelligent device widely adopts a plurality of short-distance wireless communication protocols such as Wi-Fi, zigbee, bluetooth Mesh and the like. However, these protocols are mutually incompatible at the physical layer, link layer and application layer, each forming an independent technical ecology. In this context, the HGU, which is the backbone of the home network, faces new challenges in how to effectively manage and fuse these differently-priced smart devices. The prior art mainly has the following problems and defects when attempting to solve the problem of interconnection and intercommunication of heterogeneous devices: ecological barriers are poor with interoperability-devices of different brands, different protocols, typically need to be managed and controlled by their own dedicated gateway, mobile application (App) or cloud platform. For example, a Zigbee sensor cannot directly control a Wi-Fi luminaire unless they are affiliated with a closed ecosystem. This severely limits the ability of the user to freely select and combine devices, resulting in an "ecological islanding" phenomenon. User experience splitting, namely, a user needs to install a plurality of apps in the mobile phone to respectively manage equipment with different protocols or brands. When cross-equipment linkage is performed, the setting flow is complex, a specific cloud platform is often required to be relied on or complex configuration is often performed, and real-time and reliable seamless linkage cannot be realized. The development and integration costs are high, the application developer and the device manufacturer need to adapt and develop individually for each protocol, even for each major brand ecology, the work is repeated and inefficient, and the innovation speed of the product and the application is hindered. To solve the above problems, two main technical routes are proposed in the industry, but both routes have obvious disadvantages: The first approach is multimode gateway hardware aggregation. The scheme simply integrates multiple communication chips (e.g., wi-Fi, zigbee, bluetooth chips) on a single gateway device. However, this approach only enables signal access at the physical level, and the networks of different protocols remain logically isolated from each other. When the upper layer application or the user controls, different protocol interfaces still need to be clearly distinguished and called, and the problem of interoperation of the logic layer cannot be fundamentally solved. The second approach relies on cloud platform integration. According to the scheme, devices with different protocols are firstly connected to cloud platforms of manufacturers of the devices, and then an upper third-party cloud platform (such as an intelligent sound box platform) integrates the scattered cloud services through an API interface, so that the forwarding of instructions and the exchange of data are realized. The scheme has the obvious defects that firstly, all control instructions need to go back and forth for a long distance through an external network and a plurality of cloud servers, response delay is high, experience is poor, secondly, the function of the scheme is seriously dependent on Internet connection, once a home broadband is disconnected or the cloud servers are in failure, all automation scenes of equipment can be completely disabled, intelligent home is degraded into 'artificial home', and finally, the state and the use data of user home equipment are continuously uploaded to a plurality of cloud ends, so that the risk of data privacy leakage exists. Disclosure of Invention The invention provides a unified management method and system for heterogeneous Internet of things equipment in a passive optical network, which are used for solving the defects of serious ecological barriers, poor interoperability, split user experience, excessive dependence on cloud service, high developme
