Description
Technical field
The utility model is related to a kind of detecting system, and in particular to family expenses hazardous gas detects warning system.
Background technology
The development of today's society very fast to us with easily living, the place also increasingly technicalization that people live,
More easily harmful substance has also just brought people residence, such as coal gas into.Coal gas is effective as a kind of gradual change
Combustion gas enters among the family of civic very early, but also has increasing security incident to all originate from coal gas now.Coal
The main component of gas has carbon monoxide with hydrogen, and carbon monoxide is a kind of gas of colorless and odorless, is dangerous stealthy killer：And
And coal gas or a kind of high gas of combustibility, once there is gas leak also likely to occur fire, cause bigger damage
Lose.Gas poisoning event is all occurring again and again in the whole nation or even the whole world.
Utility model content
Technical problem to be solved in the utility model is to avoid gas poisoning, it is therefore intended that provide the inspection of family expenses hazardous gas
Survey warning system, the problem of solution can not predict gas leak in advance.
The utility model is achieved through the following technical solutions：
Family expenses hazardous gas detects warning system, including main control module, water atomization module, A/D converter, coal gas detection dress
Put, warning system, the master control module controls peripheral circuit；The water atomization module is electrically connected with main control module, is let out in coal gas
Make the humidity in the water atomization in device, increase air while leakage, the dangerous burning things which may cause a fire disaster of presence is eliminated in advance；The coal gas detection
Device is electrically connected with A/D converter, and corresponding electric signal is converted into for collecting gas concentration change in collection environment；The A/
D converters are electrically connected with coal gas detection means, main control module respectively, and the information of coal gas detection means is entered by A/D converter
Row conversion, becomes the digital quantity that main control module can be recognized and judged；The warning system is electrically connected with main control module.
Further, the main control module is also electrically connected with the gas concentration in concentration display module, display air, convenient
User checks.
Further, the water atomization module is supersonic atomizer, using high frequency oscillation, and concussion frequency is
1.7MHz, more than the audibility range of people, by the high-frequency resonant of atomizing piece, water throwing is produced from the water surface the elegant water of nature
Mist.
Further, the coal gas detection means is MQ-5 gas sensors, air-sensitive used in MQ-5 gas sensors
Material is the relatively low tin ash of electrical conductivity in clean air.When there is fuel gas in sensor local environment, sensor
Electrical conductivity increase with the increase of the combustable gas concentration in air.The change of electrical conductivity can be turned using simple circuit
It is changed to the output signal corresponding with the gas concentration.Sensitivity of the MQ-5 gas sensors to butane, propane, methane is high, right
Methane and propane can preferably be taken into account.This sensor can detect a variety of imflammable gas, particularly natural gas, be a be adapted to
The inexpensive sensor of a variety of applications.
Further, the main control module is AT89C51 single-chip microcomputers, and AT89C51 is a kind of band 4K byte FLASH memories
Low-voltage, high-performance CMOS 8-bit microprocessor, be commonly called as single-chip microcomputer.
The utility model compared with prior art, has the following advantages and advantages：The utility model is provided with coal gas
Detection means and warning device, gas leak can send alarm；Provided with water atomization plant, once coal gas is leaked, in order to
Avoid occurring fire, you can increase air humidity has avoided Mars point coal gas；Considerably increase the security of indoor occupant.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding the utility model embodiment, constitutes the one of the application
Part, does not constitute the restriction to the utility model embodiment.In the accompanying drawings：
Fig. 1 is the utility model structural representation.
Embodiment
For the purpose of this utility model, technical scheme and advantage is more clearly understood, with reference to embodiment and accompanying drawing,
The utility model is described in further detail, and exemplary embodiment of the present utility model and its explanation are only used for explaining this
Utility model, is not intended as limiting of the present utility model.
Embodiment
As shown in figure 1, the utility model family expenses hazardous gas detect warning system, including main control module, water atomization module,
A/D converter, coal gas detection means, warning system, the master control module controls peripheral circuit；The water atomization module and master control
Module is electrically connected, and the humidity in the water atomization in device, increase air is made while gas leak, the danger of presence is eliminated in advance
Dangerous burning things which may cause a fire disaster；The coal gas detection means is electrically connected with A/D converter, is converted into for collecting gas concentration change in collection environment
Corresponding electric signal；The A/D converter is electrically connected with coal gas detection means, main control module respectively, by A/D converter to coal
The information of gas detection means is changed, and becomes the digital quantity that main control module can be recognized and judged；The warning system and master
Control module electrical connection.Main control module is also electrically connected with the gas concentration in concentration display module, display air, and convenient use person looks into
See.Water atomization module is supersonic atomizer, and using high frequency oscillation, concussion frequency is 1.7MHz, more than the audibility range of people,
By the high-frequency resonant of atomizing piece, water throwing is produced to the elegant water smoke of nature from the water surface.Coal gas detection means is MQ-5 coal gas
Sensor, gas sensitive used in MQ-5 gas sensors is the relatively low tin ash of electrical conductivity in clean air.Sensing
