Description
Technical field
The present invention relates to a kind of alarm of family gas leak detection and control devices, belong to intelligent early-warning equipment and technology neck
Domain.
Background technology
With the improvement of people ' s living standards with the progress of science and technology, traditional drilling wood to make fire be substituted, coal gas
Have become one of the main fuel of China town dweller with liquefied petroleum gas.Nowadays, coal gas is small in apartment, hotel, house
Area is widely used, while coal gas brings great convenience to people's life, since manual operation is improper or ageing equipment etc.
Gas leakage accident caused by a variety of causes seriously threatens the security of the lives and property of people.
Town Gas main component is that carbon monoxide is a kind of imflammable gas, when leakage concentration is more than lower explosion limit
When, if making a phone call or using household electrical appliance, coal gas, which encounters electric spark, may occur fire even explosion accident.Human body package
A concentration of 25 × 10-6Carbon monoxide in have the danger of poisoning, the consequence of anthracemia is very serious, gently then head
Dizzy, headache tinnitus dim eyesight, weakness of limbs；Heavy then person's Nausea and vomiting, unhappiness, and nerve is benumbed without moving；What is more
Stupor, convulsions, the not normal, expiratory dyspnea of stool and urine etc., when the concentration of carboxyhemoglobin in blood reaches 70%~80%,
People will be rapid dead.
Once occur gas leak, timely and reliably detect gas leak the case where, and adopt an effective measure into
Row is remedied, and using correct method of disposal, reduces the accident that leakage causes, be avoid causing great property and casualties must
Want condition.
Gas alarm controller has become a kind of quite ripe product in foreign countries, in history earliest invention gas leak detector
Country be Japan, existing more than 50 years history.Development either on gas sensor, or the detection in gas leak detector
In performance, the front end of the Japanese worlds Dou Zou.Since Japanese government and manufacturing enterprise widely popularize making for gas leakage alarm
With local gas leak and explosion accident rate are well below developed countries such as America and Europes.
China most starts early in the phase at the beginning of the seventies for the various kinds of sensors research such as wet sensitive, temperature, infrared, and achieves very
Big achievement just starts the research last decade of gas leak detector and its corresponding gas sensor.China's gas leak at present
The model of alarm is various, kind is more complete, and product quantity is also being continuously increased.In recent years, stablize in gas selection and product
Also there is great progress in property.But be mainly based upon on the basis of advanced sensing technology and the production technology of Introduced From Abroad, it carries out
Research and development, the characteristic of oneself can not be formed.Gas leak detector can be divided mainly into two classes by application occasion：Industrial coal gas
Alarm and household gas-leakage alarm device.Industrial gas leak detector can be divided into fixed and portable, fixed gas alarm again
Device is by detector and controller two parts are big forms, and is mainly used for the industrial sites such as boiler room, Vehicle Fueling Station and liquefied gas station；
Portable gas leak detector is called leak detector, it is small, convenient for hand-held or carry, the person's line walking that is mainly used for gas pipe
And leakage detection.Household fuel gas leakage alarm is a kind of small gas safety precaution product being suitable for home use, and is mainly installed
In kitchen, detected for gas leak, its development and the development of microelectric technique are closely bound up, can be divided mainly into three generations.It is existing
On the market mainly based on the third generation, in preceding two generation, is substantially eliminated due to having a single function.Third generation coal gas
Alarm can be divided into two classes, and one kind is the independent alarm for applying to single domestic applications, another kind of to apply to cell joint defence report
Alert internet alarm system.Although this two class has been quite ripe product, there are still some problems.
