Description
Technical field
This utility model is related to natural gas leaking detection technique field, especially natural gas automobile fuel gas leakage composite sensing
Device.
Background technology
Gas-fueled vehicles use natural gas as energy supply source, but natural gas safety in disposal process is unusual spine
The problem of handss, in gas-fueled vehicles, natural gas is generally divided into CNG（Compressed natural gas）And LNG（Liquefied natural gas）Two kinds.CNG vapour
After natural gas is compressed in car, 20MPa is stored in（200kg/cm2）Gas cylinder in；In LNG automobiles, natural gas Jing height is forced down
After temperature liquefaction, it is stored in less than -160 DEG C of vacuum heat-preserving tank, the pressure of general LNG gas tanks is in 1MPa（10kg/cm2）It is left
The right side, during use, due to the actual state that there is high pressure or low temperature, such as seals bad, will result in leakage, a ground
Square natural gas leaking, smokes at far place and can just cause burning even to explode, so safety is maximum in use
Problem, in general gathering system of natural gas, only with above-mentioned sensor in a kind of sensor be acquired.Due to
Various sensors have the merits and demerits of oneself, it is impossible to satisfaction have in gas-fueled vehicles strong motion, high/low temperature change, should
Sensitive, collection accurately requirement during high concentration is responded during low concentration.
Utility model content
Technical problem to be solved in the utility model is to provide natural gas automobile fuel gas leakage compound sensor.
To solve above-mentioned existing technical problem, this utility model adopts following scheme：Natural gas automobile fuel gas leakage is multiple
Sensor, including natural gas semiconductor transducer, ADC processor of single chip computer, natural gas catalytic combustion sensor are closed, it is described natural
Gas catalytic combustion sensor and natural gas semiconductor transducer are combined into compound sensor, and the interface of ADC processor of single chip computer connects
Connect natural gas catalytic combustion sensor and natural gas semiconductor transducer, ADC processor of single chip computer side connecting communication interface.
Preferably, the natural gas semiconductor transducer and natural gas catalytic combustion sensor are all connected with power supply.
Preferably, the natural gas semiconductor transducer low concentration signal quantitative collection is between 0 ~ 2000ppm.
Preferably, the natural gas catalytic combustion sensor high concentration signal quantitative collection is in 2000ppm ~ 50000ppm
Between.
Beneficial effect：
When this utility model purpose is to provide a kind of detection natural gas, low concentration sensitivity is high, and during high concentration, output signal is steady
Fixed natural gas automobile fuel gas leakage compound sensor.

Sensor, ADC processor of single chip computer side connecting communication interface, the natural gas semiconductor transducer and natural gas catalytic combustion are passed
Sensor is all connected with power supply, the natural gas semiconductor transducer low concentration signal quantitative collection between 0 ~ 2000ppm, the day
So gas catalytic combustion sensor high concentration signal quantitative collection is between 2000ppm ~ 50000ppm.
During work：Using natural gas catalytic combustion sensor and natural gas semiconductor transducer together, constitute composite sensing
Device, using signal and natural gas semiconductor transducer that natural gas catalytic combustion sensor is gathered with ADC processor of single chip computer
Signal, carry out digital water transfer, in real time output collection concentration value, when low concentration is leaked, using natural gas semiconductor transducer
Sensitive characteristic is responded during low concentration, carrying out 100ppm ~ 2000ppm signals carries out quantitative collection, to 2000ppm ~ 50000ppm
Qualitative collection is carried out, when higher concentration is leaked, using natural gas catalytic combustion Sensor output linearity, the high spy of degree of stability
Property, enter carries out qualitative collection to 2000ppm ~ 40000ppm, in natural gas gas leakage in low concentration（0~2000ppm）When, response
Sensitivity is 100ppm, and resolution is 100ppm, and accuracy is ± 200ppm, and natural gas leaking is in high concentration（2000~
50000ppm）When, response sensitivity is 1000ppm, and resolution is 1000ppm, and accuracy is ± 1000ppm.
After collection signal is filtered process to more than, digital signal output can be carried out, and numerical value show, network it is remote
Pass etc..
This utility model needs the test point for detecting natural gas leaking to carry out natural gas suitable for gas-fueled vehicles industry
Easily there is natural gas in Leak Detection, such as gas cylinder cabin, inflation inlet, air relief valve, gas pipeline, natural road valve, electromotor etc.
The place of leakage.
Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute
