Description
Technical field
The utility model relates to gas meter technologies, and in particular to gas alarm coordinated control system.
Background technique
It currently, Household gas warner only has warning function, can not link with stop valve, realize self-closing valve
Door, cuts off the effect of gas source, it is ensured that with gas safety.Even by patent in refer to fuel gas alarm and stop valve forms
Linked system, and since the installation of gas cut off valve needs the personnel of profession, it is personal to be installed privately there are great security risk,
And gas company be do not allow it is personal install, meanwhile, fuel gas alarm is easy to appear wrong report and limits this linkage in this way
The use of system.
Chinese patent CN 107606299A " fuel gas alarm wireless control closes valve system ", which includes valve control device
With N number of gas detection alarm device relevant to valve control device,Valve control device and gas detection alarm device use wireless signal Connection；Gas detection alarm device acquisition gas alarm information after output signal to valve control device andIntelligent radio collector, valve
Control device includes receiving module and valve module is closed in early warning, and receiving module is used to receive the alarm signal of gas detection alarm device output
Breath,Early warning closes valve module and carries out early warning pass valve events cutting gas source according to warning message, intelligent radio collector by wireless or
Wired connection network and server, for managing administrative gas detection alarm device, and by the shape of gas detection alarm device
State information reporting server.
The patent is examined using 470M GFSK standard, Lora, 2.4G or Zigbee wireless signal connection valve control device, gas
