Information synchronization method based on distributed storage in intelligent lighting system

Abstract

The invention provides a real-time information synchronization method based on distributed storage in an intelligent lighting system. The present invention changes the intelligent lighting system information required for user control from centralized storage to distributed storage in three parts: the logical relationship between lights and rooms is stored in the server; the status information of the wireless network is stored in the gateway; the status of the lights is accessed through real-time get. In the present invention, the information is updated when the client APP is initialized, and the logical relationship between the lamp and the room is updated according to the network quality. When there is no Internet, the user cannot obtain this part of the latest information from the server, then use the last synchronization information with the server, and perform information synchronization immediately when the server can be connected to the server next time. The status update of the light can be carried out in the local area network, which improves the speed of network transmission while saving traffic. Users can keep information synchronized with other users when controlling lights.

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
