As the number of uses of the gas sensing device 40 increases, the sensing element 44 causes an error in detecting the exhaust gas, and therefore needs to be corrected after a certain number of uses. This creation includes scale correction and linear correction.

1, proportional correction

When performing the proportional correction, referring to FIG. 5, the sensing component 44 is directly connected to a standard gas line through the air pump 43 to receive a standard gas, the standard gas contains a known gas concentration to be tested, and the application is available. The user sets a standard value of the gas concentration to be measured, and the standard value of the gas concentration to be measured is equal to the known gas concentration of the standard gas to be tested. The sensing component 44 senses the standard gas and outputs an exhaust gas information, the exhaust gas information including a gas concentration sensing value to be measured. The mobile communication device 20 can perform the proportional correction mode according to the user's operation (for example, the user presses the proportional correction mode function on the operation interface).

Because the gas concentration sensing value of the gas to be tested does not necessarily meet the standard value of the gas concentration to be tested, the mobile communication device 20 calculates a dilution coefficient X of the gas to be tested through a proportional correction formula, and the ratio correction formula is expressed as follows:  <TABLE border="1" borderColor="#000000" width="85%"><TBODY><tr><td> </td><td> X×A+(1-X)×B = C </ Td><td> </td></tr></TBODY></TABLE>

In the above formula, A is the standard value of the gas concentration to be tested; B is the concentration of the gas to be tested in the atmosphere, and B is 0 or a constant. For example, the B value of carbon monoxide and hydrocarbon is 0%, and the B value of carbon dioxide. It is 0.04%; C is the measured value of the gas concentration to be measured. Therefore, the mobile communication device 20 can calculate the dilution coefficient X of the gas to be tested.

The mobile communication device 20 performs proportional correction on the gas concentration sensing value D to be measured according to the measured gas dilution coefficient X, and displays and transmits it to the cloud background 30. The corrected gas concentration sensing value after the calibration is expressed as follows: [D-(1 -X)×B]/X

For example, when the probe 41 of the gas sensing device 40 is connected to the exhaust pipe to actually perform the exhaust gas detection, the carbon monoxide concentration sensing value of the exhaust gas information outputted by the gas sensing device 40 is D ₁ , and then corrected. The carbon monoxide concentration value may be D ₁ /X ₁ , wherein X ₁ is a carbon monoxide dilution coefficient; when the carbon dioxide concentration sensing value of the exhaust information outputted by the gas sensing device 40 is D ₂ , the corrected carbon dioxide concentration value may be Is [D ₂ -(1-X ₂ )×B ₂ ]/X ₂ , where X ₂ is a carbon dioxide dilution coefficient; when the hydrocarbon concentration value of the exhaust information outputted by the gas sensing device 40 is D ₃ , the correction is The subsequent hydrocarbon concentration value can be D ₃ /X ₃ , where X ₃ is the hydrocarbon dilution factor.

2, linear correction

The linear correction includes a zeroing correction step and a standard gas calibration step. In the zero correction step, the gas sensing device 40 does not receive the exhaust gas and first senses, and the generated exhaust information includes a gas concentration to be measured as a The initial zero value x ₀ , then the gas sensing device 40 is in a ventilated environment, and is continuously ventilated for a period of time (about 1 minute) to eliminate the accumulated gas in the pipeline, at which time the gas sensing device 40 is activated. Sensing, the generated exhaust gas information includes the gas concentration to be measured as a zero return correction value y ₀ , y ₀ =0, that is, the initial zero return value x ₀ is sensed before the accumulated gas in the pipeline is excluded. The value obtained, the zero correction value y ₀ is the value sensed after the accumulated gas in the pipeline is excluded.

In the standard gas calibration step, the probe 41 of the gas sensing device 40 is connected to a standard gas line to receive a standard gas containing a known gas concentration to be measured, and the application is user-configurable. a standard value of the gas concentration to be measured, the standard value of the gas concentration to be measured is equal to the known gas concentration of the standard gas to be tested, and the gas sensing device 40 senses the standard gas and outputs an exhaust gas information, the exhaust gas The information includes a gas concentration sensing value x _{1 to} be measured, and the gas concentration sensing value x ₁ to be measured is transmitted to the mobile communication device 20.

After receiving the gas concentration sensing value x _{1 to} be measured, the mobile communication device 20 calculates a difference between the gas concentration sensing value x ₁ to be measured and the standard value of the gas concentration to be measured to generate a deviation value offset. As such, referring to FIG. 6, the mobile communication device 20 can obtain a linear expression through two points (x ₀ , y ₀ ) and (x ₁ , y ₁ ) of the rectangular coordinates, y ₁ = x ₁ + offset, The linear expression can be expressed as y=ax+b, where y is the corrected gas concentration value to be measured, x is the gas concentration sensing value to be measured, and a and b are constants. The mobile communication device 20 stores the linear operation formula as a basis for linear correction. For example, when the subsequent detection is performed, the received carbon monoxide concentration sensing value x is substituted into the linear operation formula to obtain a linearly corrected Carbon monoxide concentration sensed value y.

In summary, the present embodiment has the following advantages:

1, modular architecture, reduce costs

In terms of hardware specifications, this creation abandoned the industrial computer as the core, and changed to a single chip as the main core, and the modular design inside the body to reduce raw material costs and maintenance costs.

2, the detection of environmental freedom, users do not need to suck the exhaust gas behind the car

Most of the exhaust gas detectors on the market display data and control the machine by monitoring the touch screen of the host computer. The present embodiment uses Bluetooth wireless transmission technology to display data and conduct data through the mobile communication device. Related controls are relatively free.

3. Data analysis

When the mobile communication device 20 executes the application, the composite information transmitted by the exhaust information output device 10 is received, and the composite information is directly uploaded to the cloud background 30 to form historical data, and the supplier provides the consumer with more accurate data according to the historical data. Analysis results.

4, gas utilization calculation correction

The user can directly correct it through the mobile communication device 20, and the operation is simple and convenient, and the manufacturer calibration can be omitted.

5, the foolproof mechanism, reduce the abnormality of the sensing component is still detected

As long as the traditional detector can display the sensed value, unless it is an extreme value, the average user will not question the accuracy. In other words, if the conventional detector is out of alignment, the average user may not be able to detect it immediately. The present invention can determine whether the sensed value is abnormal in each detection, so that when the abnormality is detected, the mobile communication device 20 can execute the lock mode and display an abnormal lock screen, and the abnormal lock screen is used to indicate to the user that the next step should be What to do.
