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 module unit, 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 fuel gas 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 relates to the field of safe and energy-saving smart gas meters. Background technique [0002] At present, all kinds of smart gas meters or gas stoves in the prior art do not have the function of automatically cutting off the gas when the owner leaves the room without people. If the owner forgets to turn off the gas stove or gas appliance in use when he goes out A waste of gas will leave a potential fire hazard. If it is not done well, a fire will cause major losses to your property and society. Summary of the invention [0003] In order to overcome the above-mentioned safety and energy-saving defects in various smart gas meters or gas stoves in the prior art, the present invention applies advanced wired or wireless coding remote control technology to divide the infrared human body signal detection device and the smart gas meter control device into a host and The extension unit is designed and used as a complete set. The host is an infrared h...
