Description
Technical field
The present invention relates to electronic monitoring field, more particularly to a kind of combustible gas alarm method and flammable gas alarm.
Background technology
As the user of fuel gas is continuously increased, the safety such as a series of poisoning, blast that fuel gas leakage is caused
Event gradually causes the concern of society, wherein, the problems such as user can not in time have found the leakage of fuel gas, to user and
Society brings more serious potential safety hazard.
Therefore, combustible gas detector miscellaneous and flammable gas alarm are occurred in that on market.Combustible gas health check-up
It is that, to single or many combustible gases concentration-response detector, it is that function is most complete using intelligent sensing transmitter to survey instrument
Fuel gas sensing transducer, this intelligentized sensing transducer adopts the MicroSafe software engineerings of Detcon companies.Adopt
Interference-free operation interface, all of operation is used all to be menu modes and can carry out by a hand-held magnetic programming tool.
The output of standard includes 4-20mA outputs, RS-485 communication interfaces and 3 alarm relays；The signal transmission mould of sensing transducer
Block is plug-type, thus facilitates on-site maintenance.When industrial environment, everyday environments (such as the kitchen using natural gas)
Middle imflammable gas is revealed, and existing flammable gas alarm detects imflammable gas concentration and reaches alarm setting
During alarming value, flammable gas alarm will send sound, visual alarm, take evacuating personnel, force air draft, close down to remind
The safety measures such as equipment, prevent the accidents such as blast, fire, poisoning, so as to ensure safety.But sound and light alarm is only to surrounding
In the case of someone effectively, can not handle it in time in the case of surrounding no one.
On the other hand, with the fast development of science and technology, people require more and more higher to intelligence degree.Single-chip microcomputer is one
To on a chip, the use field of single-chip microcomputer is quite varied, and various products have once used monolithic for Computer systems
Machine, can just play the effect for making the updating and upgrading of a product, substantially increase the intellectuality of product.And mobile phone is the most convenient as people
