It is including the gas sensor who is used for tracer gas for detecting the temperature sensor of temperature and being used for information processing's processing unit, gas sensor's signal output part is on gas sensor detection circuitry is connected to processing unit, and temperature sensor's signal output part is connected to on the processing unit through temperature sensor detection circuitry, processing unit's output passes through PWM output signal and connects alarm device. After adopting foretell structure, under the environment of maring concentration, obtain under each temperature gas sensor to a's DEG C RS's ratio, the K of RS compensation promptly value, real -time detection two dynamic values, its structural design is ingenious, portably easy -to -use, be applicable to various applied environments, the warning was revealed to the product reliability, uniformity and security has improved greatly, can effectual prevention leak the injury to the person and property that causes because of the gas with control.
Description
Technical field
The utility model is related to a kind of detector module, specifically a kind of temperature compensating gas detector module.
Background technology
At present, natural gas/liquefied gas due to low cost, the impact to environment it is little so as to being widely popularized, being applied, by
Cause natural gas/liquefied gas that the valve and pipe of pipeline or gas bomb can be made when normally using in the characteristic of natural gas/liquefied gas
There is the possibility of leakage in road, there is certain potential safety hazard, be used using detection alarm device monitoring combustion gas
Situation, however in existing detection alarm device sensor when use environment temperature rises, characteristic RS can reduce, opposite characteristic
RS can increase；When sensor is when object gas have been detected, characteristic RS also can reduce, and warning device thus can be caused to report by mistake
Alert, early warning, evening paper are warned, are not even reported to the police, and have impact on the reliability for using.
The content of the invention
The technical problems to be solved in the utility model is to provide one kind and can perceive use environment temperature, to gas sensor
Internal resistance RS characteristics make compensation, so as to improve the temperature compensating gas detector module of use environment Acclimation temperature ability.
In order to solve above-mentioned technical problem, temperature compensating gas detector module of the present utility model, including for detecting
The gas sensor of gas, the temperature sensor and the processing unit for information processing for detection temperature, gas sensing
The signal output part of device is connected on processing unit through gas sensor detection circuit, the signal output part Jing of temperature sensor
Excess temperature sensor detection circuit is connected on processing unit；The output end of processing unit is reported to the police by PWM output signal connection
Device.
The output end of the processing unit connects LED light through LED light drive circuit.
Have for the input port of input information in processing unit on the processing unit.
After using above-mentioned structure, the gas sensor that is connected with processing unit and TEMP while due to arranging
Device, thus in the environment of concentration is demarcated, obtains ratio of the gas sensor to a DEG C of RS at each temperature, i.e. RS compensation K values；
Dynamic two values of real-time detection, its smart structural design, it is easy it is easy-to-use, suitable for various applied environments, substantially increase product
Product reveal reliability, uniformity and the security reported to the police, can effectively prevent and control because gas leakage cause to the person
With the injury of property.
Description of the drawings
Fig. 1 is the theory diagram of the utility model temperature compensating gas detector module.
Specific embodiment
With reference to the accompanying drawings and detailed description, temperature compensating gas detector module of the present utility model is made into one
Step is described in detail.
As illustrated, temperature compensating gas detector module of the present utility model, including passing for the gas that detects gas
Sensor, the temperature sensor and the processing unit for information processing for detection temperature, the signal output of gas sensor
End is connected on processing unit through gas sensor detection circuit, and the signal output part of temperature sensor is through temperature sensor
Detection circuit is connected on processing unit；The output end of processing unit connects warning device, processing unit by PWM output signal
Output end through LED light drive circuit connect LED light, on processing unit have be used for into processing unit be input into
The input port of information.
Further, upwards transmission port for uploading information is also associated with described processing unit and for download information
Download port, upwards transmission port and download port can be connected the upload and download for carrying out information data with external equipment.
Its operation principle is as follows：
First, demarcated：Under a certain fixed temperature, by the object gas of concentration to be calibrated " gas sensing is given
Device ", draws signal mode analog quantity to processing unit by " gas sensor detection circuit "（MCU）, MCU inside AD conversion is into numeral
Amount storage is in the inside power-failure memory EEPROM of processing unit.
Secondly, demarcate in the environment of concentration, obtain ratios of the sensor RS to a DEG C of RS at each temperature, i.e. RS compensation K
Value；
Finally, dynamic two values of real-time detection, one is temperature value, and one is sensor RS.
In the middle of detection process, the digital quantity that there will be first in EEPROM reads, and is converted to the RS values of sensor；
Secondly, by the change of " temperature sensor " sense temperature, through " temperature sensor detection circuit ", being converted to can
To MCU, into digital quantity, each digital quantity corresponds to a temperature to MCU inside AD conversion to the analog quantity of identification；
While detection sensor RS：Real-time detection " gas sensor " electrical quantity, by " gas sensor detection circuit "
Signal mode analog quantity is drawn to MCU, digital quantity is converted to sensor RS by MCU inside AD conversion into digital quantity；
Finally calculated and judged：The RS*K values of real-time detection, such as this value are revealed less than RS values are demarcated, then and reported to the police.
