Information synchronization method based on distributed storage in intelligent lighting system

Abstract

The invention provides an information synchronization method based on distributed storage in an intelligent lighting system. According to the information synchronization method, intelligent lighting system information needed by user control is stored in a distributed manner from a centralized manner in three ways: a logical relationship of a lamp and a room is stored in a server; state information of a wireless network is conserved in a gateway; and the state of the lamp can be obtained by accessing to the lamp in real time. When a client APP (Application) is initialized, information is updated, and the logical relationship of the lamp and the room is updated according to the network quality. When there is no Internet and users cannot obtain this part of latest information from the server, then information synchronized with the server last time is used, and information synchronization is performed immediately when the server can be connected next time. State updating of the lamp can be performed in a local area network, thus traffic can be saved and the network transmission speed can be improved. Users can keep information synchronization with other users while controlling the lamp.

Description

technical field [0001] The invention relates to an information synchronization method of an intelligent lighting system, in particular to an information synchronization method based on distributed storage in an intelligent lighting system. Background technique [0002] With the public's gradual recognition of the indoor intelligent lighting system, the system has developed from a simple mobile phone operation function to a multi-platform, multi-user, internal and external network that can be operated at the same time. At present, in a typical indoor intelligent lighting system, all indoor lights are interconnected with the gateway through (wifi, zigbee, private protocol, etc.), and are connected to the Internet through the gateway to communicate with servers, mobile phones, etc. Based on this architecture, the system can realize the user's operation of the lamp through multiple terminal platforms (WeChat, IOS, Android, etc.), and can realize the simultaneous control of diffe...

Problems solved by technology

However, due to the uncertainty of Internet communication delay and network instability, it brings great challenges to the design of real-time information synchronization of the system.

[0003] Another example is the Chinese patent 201510405881.X, which uses cloud push based on MQTT technology. Subscribers can get all the news of the topic by subscribing to a specific topic, which realizes information synchronization. The disadvantage is that all information in the existing system is stored. In the server, the information required by the user must be obtained from the server through the Internet

When the user cannot connect to the Internet, the information cannot be synchronized, and the system cannot work normally

Systems using the above mechanisms also cannot operate within a LAN
