Communication module connection.Main control end obtains kitchen by the data at the end continuous poll ZigBee wireless communication module Coordination
The data of room gas concentration, when the value reaches a certain LEL value, Arduino UNO sends instructions to ZigBee
The end Coordination, and the end will send to the end ZigBee Router and instruct, it is contemplated that the end Router for receiving order is receiving
After order, then carry out internal control.
In embodiment, the ZigBee power supply of wireless electric-controlled valve is arranged to a Router, is subjected to switch order.
In embodiment, the ZigBee power supply of wireless electric-controlled exhaust fan is configured to a Router, and acceptable switch refers to
It enables.
When Arduino embedded program, which receives LEL, crosses the data of limit, warning message can be sent by wireless network.
Such as using GRPS network communication, short message can be directly transmitted to house-owner；Or communicated using WIFI network, then it can be to
Gas Group control centre sends warning message, sends alarm to house-owner by special service number from Gas Group.
The present invention is different from generally requiring the smart home system of intelligent gateway control.It has fully considered municipal cable intelligence
Transformable practicability is chosen the scheme for capableing of low consumption work steady in a long-term, and is stayed to existing urban operating mechanism and server-side
There is interface, so that the design efficiency of entire scheme is high, effectively prevents repeated construction.
The present invention is not limited to the above embodiments, and various modifications may be made in the scope of the inventive concept.The present invention
It is illustrated through the foregoing embodiment, but it is to be understood that, the above-mentioned embodiments are only for the purpose of illustration and description,
It is not intended to limit the invention to the scope of the described embodiments.Furthermore it will be appreciated by persons skilled in the art that originally
Invention is not limited to above-described embodiment, and introduction can also make more kinds of variants and modifications according to the present invention, these modifications
All fall within the scope of the claimed invention with modification.Protection scope of the present invention by the appended claims and its
Equivalent scope is defined.
