Safe and energy-saving -type intelligent gas meter possessing unmanned automatic gas-cutting function

Abstract

The invention is related to a safe energy saving intelligent fuel gas meter having unmanned automatic switching fuel gas function. A main frame uses a single machine chip as a main control unit composed of an instruction signal coding transceiving module unit, a study pair code and state display or turnover number of people display unit, a voice recording and playing unit, an infrared ray human body detection sensor unit; a branch machine also uses a single machine chip as a main control unit composed of an instruction signal coding transceiving module unit, a fuel gas leakage alarming moduleunit, an instruction output control gas valve unit and a study pair code and state display unit. The invention applies coding remote control technology, infrared ray human body detection technology to overcome defections of various intelligent fuel gas furnaces not capable of automatically switching fuel gas when there is nobody in the room in prior art thoroughly, to use various intelligent fuelgas meters and fuel gas furnaces safer, more reliable and energy saving, which greatly improves safe and energy saving value and practical range of the various intelligent fuel gas meters and fuel gas furnaces having great market foreground.

Description

Technical field [0001] The invention involves safety energy -saving intelligent gas meter fields. Background technique [0002] At present, the existing technologies do not have the function of automatic cutting gas when the owner leaves the room without anyone when he leaves the room.Wasting gas, a large fire hazard is left, and it is not possible to cause a major loss to your property and society. Invention content [0003] In order to overcome the above -mentioned safety energy saving defects of various intelligent gas meters or gas stoves of existing technologies, the advanced wired or wireless coding remote control technology applied by the present invention, and the infrared human body signal detection device and intelligent gas meter control device are dividedExtension combination is designed and used for use. The host uses a single -chip microcomputer for the infrared human body signal detection device.Unit, the host power supply unit is composed of the host; the exten...
