Abstract
The invention relates to a multi-parameter gas sensor compensating method which comprises the following steps of: arranging ambient temperature, ambient humidity, air pressure and wind speed sensors near a gas sensor, wherein the gas sensor and the ambient temperature, ambient humidity, air pressure and wind speed sensors are connected with a controller on a gas detection meter; storing ambient temperature, ambient humidity, air pressure and wind speed compensation values corresponding to each state point in the controller of the gas detector meter; measuring after self-checking, and obtaining measurement initial values, ambient temperature, ambient humidity, air pressure and wind speed values corresponding to measurement time points by the controller; obtaining ambient temperature, ambient humidity, air pressure and wind speed compensation values corresponding to the measurement time points by the controller according to the ambient temperature, ambient humidity, air pressure and wind speed values; carrying out compensation correction operation on the measurement initial values and the ambient temperature, ambient humidity, air pressure and wind speed compensation values by the controller; and outputting data on an output device of the gas detection meter. The invention ensures that the measurement precision is greatly increased, and the use range is greatly enlarged.
Description
Technical field
The present invention relates to a kind of gas sensor compensation method, the compensation method of especially a kind of many reference amounts gas sensor.
Background technology
Gas sensor on the detection of gas metering device is environment sensitive to external world usually.If it is not compensated (correction), the data of measuring often exist than mistake.Current current way is that it is carried out temperature compensation.Specific practice is: the numerical value (being modified value) that each temperature spot need be increased or reduce is kept in the instrument.During the instrument output data, increase or reduce corresponding data, and then realize the purpose of temperature compensation according to modified value.
But there is inherent shortcoming in single temperature compensation.Gauge sensor is not only to responsive to temperature, humidity, pressure, gas velocity ... All sensor there is influence in various degree, can causes error not of uniform size.If instrument does not compensate, revises above-mentioned Several Factors, in the more abominable place of some environment, gas detector can't operate as normal.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide a kind of and can reduce measuring error, be applicable to that multiple environment occasion carries out the many reference amounts gas sensor compensation method of work.
According to technical scheme provided by the invention, the compensation method of said many reference amounts gas sensor comprises the steps:
A, near gas sensor installation environment temperature sensor, ambient humidity sensor, ambient pressure sensor and ambient wind velocity sensor; Gas sensor, environment temperature sensor, ambient humidity sensor, ambient pressure sensor and ambient wind velocity sensor all with the detection of gas instrument on controller link to each other, and ambient temperature compensation value, ambient humidity offset, ambient pressure offset and ambient wind velocity offset that each state point is corresponding are kept in the controller of detection of gas instrument;
B, unlatching detection of gas instrument are measured after the self check of detection of gas instrument, and the controller on the detection of gas instrument obtains Measuring Time point corresponding gasmetry initial value, ambient temperature value, ambient humidity value, ambient pressure value and ambient wind velocity value automatically;
C, obtain the corresponding ambient temperature compensation value of Measuring Time point, ambient humidity offset, ambient pressure offset and ambient wind velocity offset automatically with the ambient wind velocity value controller according to ambient temperature value, ambient humidity value, ambient pressure value;
The controller of d, detection of gas instrument will measure initial value automatically and ambient temperature compensation value, ambient humidity offset, ambient pressure offset and ambient wind velocity offset compensate and correct computing;
Output data on the output device of detection of gas instrument is revised after the computing in e, compensation.
The invention enables measuring accuracy to improve greatly, it is wide that usable range also becomes greatly, can use in the more abominable place of some environment.
Embodiment
Below in conjunction with specific embodiment the present invention is described further.
The compensation method of a kind of many reference amounts gas sensor comprises the steps:
