Embodiment Construction

[0050] The following is a further description of the present invention in conjunction with the accompanying drawings.

[0051] combine figure 1 , the system includes: a gateway control system, a local server and an intelligent device control system, and a mobile terminal device.

[0052] Among them, the gateway control system includes the main control gateway and the terminal gateway. The main control gateway and the terminal gateway are connected by the RPC protocol. The terminal gateway is connected to the Zigbee coordinator by a variety of embedded Linux control boards; Optical alarms, smart locks, fresh air systems, air-conditioning equipment, electric curtains and Zigbee sub-devices connected to Zigbee modules; local servers can be placed at home or in the computer room of community property management according to needs; mobile terminal devices include daily use mobile phones or tablet etc.

[0053] As a specific example: the control boards of the main control gateway ...

Abstract

The invention discloses a terminal gateway load distribution method based on a hash algorithm in a smart home system. The load distribution of the present invention is in the network that is made up of a plurality of terminal gateways and local server, terminal gateway utilizes Zigbee coordinator to receive the sensor data sent from Zigbee sub-equipment, and store on the server; Divide into multiple small areas and map to the hash ring, replace the position of the terminal gateway on the hash ring with virtual nodes, and use the number of virtual nodes to represent the computing power of the terminal gateway, that is, when the terminal gateway joins the edge computing network, The master control gateway assigns a corresponding number of virtual nodes to the terminal gateway according to the computing power of the terminal gateway, and maps its virtual nodes to the hash ring with a hash function. The virtual nodes capture the data closest to it in a fixed direction, so that the The gateway system that enters the edge computing state has the ability to dynamically join and exit the edge computing network while still achieving load distribution according to the ratio of computing power.

Description

technical field [0001] The invention discloses a terminal gateway load distribution method based on a hash algorithm in a smart home system. Background technique [0002] Smart Home is that thing connectionization embodies under the influence of Internet of Things. Smart home connects various devices in the home (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital cinema system, audio and video server, shadow cabinet system, network appliances, etc.) Home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, HVAC control, infrared forwarding and programmable timing control and other functions and means. Compared with ordinary homes, smart homes not only have traditional residential functions, but also include construction, network communications, information appliances, and equipment automation, providing a full range of...
