Art.
Workflow wherein based on the switch product of ZigBee technology is probably as follows：As switch product (EndDevice)
After being user-operably, the information transmission that corresponding device is opened or closed to node-routing (Router), information is in node-routing
(Router) transmit between, be finally transferred on the core coordinator Coordinator of whole ZigBee-network (in smart home
Claim wireless apss), then gateway is communicated information to by core coordinator, the corresponding device of so far switch product transmission is beaten and is opened or closed
The information closed enters the Internet, and its specific transmission path is as follows：
End Device (switch module) → Router (route) →.... → Coordinator (coordinator) → GateWay
(gateway) → Internet (the Internet).
As for the switch product based on 433MHz wireless technologys, its workflow is typically as follows, and switch product sets correspondence
The standby information transmission for opening or closing is to the 433MHz modules in ap mode, i.e. wireless data exchange center (similar ZigBee
Coordinator) on, then wireless data exchange center exchanges information with gateway.The specific following institute of information transmission path
Show：
STA (switch module) → AP (wireless data exchange center) → gateway (GateWay) → Internet (the Internet).
But, above switch product is not assigned to IP address when implementing, so merely by AP or association
Adjust device to control to recognize each switch product, switch is used alone, and method does not work in a network.This causes entering
The operation required when extending of row network is more complicated.Such as, the switch product based on ZigBee technology needs many in extension
Router relaying could in information transmission to coordinator, if a newly-built network then also needs to additional coordinator,
And make coordinator access network.And the switch product for being based on 433MHz technologies then needs to set up wireless messages switching centre (AP),
Also to be attached using some communication modes (485,422 buses etc.) between multiple AP simultaneously, cabling is also cumbersome.
Furthermore, 433MHz technologies use the radio band of 433MHz, although so that aerial signal possesses higher wearing
Permeability and transmission range, but but cause transfer rate to have a greatly reduced quality, and relatively common speed only only has 9600bps.And
ZigBee technology is the application for being positioned at low transmission rate, is not suitable for high speed Internet access, or the occasion such as file download greatly.In addition
The host-host protocol that 433MHz technologies are used is data transparent transmission agreement, easy solicited message safety problem.
