Description
Technical field
The present invention relates to field of gas detection, and in particular to be a kind of combustible-gas detector.
Background technology
Fuel gas such as natural gas, liquefied petroleum gas, coal gas, hydrogen etc. meet fire in atmosphere or fire easily occurs for spark
Lives and properties are caused very big threat by calamity and blast.Exploded to prevent fuel gas from reaching after finite concentration, to ensure life
Production safety, usually needs to set flammable gas detecting alarm device in production and factory using fuel gas or place.It is this
The main composition position of flammable gas detecting alarm device is combustible gas sensor, usually fixed, can only detect fixation
The fuel gas in place, it is very inconvenient when needing to detect other places or need detection different location.Detecting instrument
Portability and ease for use, to detecting that the effect of work plays an important role.
To sum up, a kind of portable combustible-gas detector how is designed, becomes and needs solution badly for those skilled in the art
One of certainly the problem of.
The content of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of combustible-gas detector.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of combustible-gas detector, including housing, are arranged on air inlet on housing, display screen, ON/OFF switch, inspection
Survey key and query key, and be arranged in housing circuit main board, microprocessor, combustible gas sensor, signal amplification circuit,
Filter circuit, analog to digital conversion circuit, power supply, memory and alarm module；The combustible gas sensor and air inlet
Turn on and pass sequentially through signal amplification circuit, filter circuit, analog to digital conversion circuit and microprocessor are connected, the microprocessor point
Be not connected with memory, alarm module and display screen, the circuit main board respectively with power supply, ON/OFF switch, detection
Key, query key and microprocessor connection.
Further, the external serial ports being connected with microprocessor is provided with the housing.
Specifically, the combustible gas sensor is constant potential electrochemical gas sensor.
Specifically, the power supply is lithium battery.
Compared with prior art, the invention has the advantages that：
It can be contrasted during combustible-gas detector detection of the present invention with default standard content, and comparing result is shown
On a display screen, also with overload alarm function.The fuel gas data of holder storage detection are provided with, can be with query history
Data are easy to determine fuel gas changes of contents situation with current data contrast, and line number can be entered with computer provided with external serial ports
According to transmission, it is easy to detect the processing of data, record and stores.Constant potential electrochemical gas sensor stability is high, lightweight, consumption
Electricity is few.Power supply is lithium battery, and battery capacity is big, lightweight and chargeable.This combustible-gas detector is hand-held, behaviour
Make convenience, compact, be easy to carry, different location measurement fuel gas content can be taken as needed, it is convenient and practical.
Brief description of the drawings
Fig. 1 is general structure schematic diagram of the invention.
Wherein, reference is corresponding entitled：
1- housings, 2- air inlets, 3- display screens, 4- ON/OFF switches, 5- detection keys, 6- query keys, 7- circuit main boards, 8-

8th, signal amplification circuit, filter circuit, analog to digital conversion circuit, power supply 9, memory and alarm module；The combustible gas
Body sensor 8 and air inlet 2 turn on and pass sequentially through signal amplification circuit, filter circuit, analog to digital conversion circuit and microprocessor
Connection, the microprocessor is connected with memory, alarm module and display screen 3 respectively, the circuit main board 7 respectively with power supply
Power supply 9, ON/OFF switch 4, detection key 5, query key 6 and microprocessor connection.
The external serial ports 10 being connected with microprocessor is provided with the housing 1.
The combustible gas sensor 8 is constant potential electrochemical gas sensor.
The power supply 9 is lithium battery.
Combustible-gas detector of the present invention is hand-held, easy to operate, compact, is easy to carry, can be as needed
Different location measurement fuel gas content is taken, it is convenient and practical.
Above-described embodiment is only one of the preferred embodiment of the present invention, should not be taken to limit the protection model of the present invention
Enclose, it is all the present invention body design thought and mentally make have no the change of essential meaning or polishing, what it was solved
Technical problem is still consistent with the present invention, should be included within protection scope of the present invention.
