Description

Technical Field

[0001] The present invention relates to the technical field of oxygen sensor deviation compensation, and in particular to an oxygen sensor deviation compensation method, device, electronic equipment and storage medium. Background Art

[0002] The structure of the electrochemical cell oxygen sensor consists of a cathode, an anode and an electrolyte. Its two electrodes, the cathode is a piece of PTFE (polytetrafluoroethylene) coated with an active catalyst, and the anode is a lead block. Oxygen enters the working electrode through the permeable membrane. When oxygen reaches the working electrode, it is immediately reduced to release hydroxide ions: O2+2H2O+4e→4OH - These hydroxide ions pass through the electrolyte to the anode (lead), where they react with lead to form the corresponding metal oxide. 2Pb+4OH→2PbO+2H2O+4e - The above two reactions generate current, and the magnitude of the current depends on the oxygen reaction rate (Faraday's law). By connecting an external load resistor to measure the potential difference, the oxygen concentration can be accurately measured. However, since the lead electrode participates in the oxidation reaction in the chemical reaction, the lead in the sensor is continuously oxidized and consumed. The gradual decrease in the amount of lead means that the electrochemical reaction gradually decays, the oxygen reaction rate of the sensor will gradually slow down, and the oxygen concentration fed back by the sensor will have a gradually lower deviation from the oxygen concentration in the environment.

[0003] In the application process, compensation and calibration are usually performed for this deviation. The general method is to perform time axis attenuation compensation based on the attenuation curve provided by the sensor manufacturer to eliminate the deviation caused by sensor attenuation. This method is effective and accurate for the compensation correction of sensors in the same batch and the initial use of sensors. However, due to differences in production processes for different batches, the compensation revision of sensors will deviate. Especially for sensors that have been used for 1 year, different attenuation will occur due to the use environment and working conditions. Since the attenuation curve provided by the manufacturer is an ideal curve for the test environment, compensation based on this curve cannot correctly correct the deviation of the sensor. In addition to this method, the atmospheric pressure reference method is also used, which is to calculate the oxygen content in the air based on the atmospheric pressure at a certain moment, and use this as a reference to correct the deviation of the sensor. Although this method can compensate for the shortcomings of the curve to a certain extent, the atmospheric pressure cannot truly reflect the oxygen content in the air. The SF6 gas leakage online monitoring and alarm device mainly monitors SF6 gas. The mass of SF6 gas is about 5.1 times that of air. When exposed to the air, it will sink rapidly and squeeze out the air, causing local hypoxia. When it reaches 10 or 100 times the dangerous value, the impact on the ambient atmospheric pressure is negligible. If the oxygen content calculated based on the atmospheric pressure is compensated at this time, it will be seriously inaccurate.

[0004] Therefore, in order to improve the deviation compensation efficiency of oxygen sensors and solve the technical problem that the existing oxygen sensors have deviations in collected data due to differences in production processes and different operating environments and working conditions, it is urgent to construct an oxygen sensor deviation compensation method.

[0051] Step S103, obtaining the oxygen value of the oxygen sensor according to the preset first cycle;

[0052] In an embodiment of the present invention, the oxygen value of the oxygen sensor is periodically acquired according to the preset first period, and when the temperature of the measured environment in a pure air environment is different from the temperature of the current environment, the oxygen value is compensated for the temperature difference.

[0055] In an oxygen sensor deviation compensation method provided in an embodiment of the present invention, through step S101, first oxygen content data of a measured environment in a pure air environment and second oxygen content data of the measured environment in an atmospheric pressure environment are obtained; in step S102, a difference between the first oxygen content data and the second oxygen content data is set as an error threshold; in step S103, an oxygen value of the oxygen sensor is obtained according to a preset first cycle; in step S104, based on the oxygen content data in different environments and the error threshold, abnormal data in the oxygen value is compensated and corrected to obtain a corrected oxygen value. Through an oxygen sensor deviation compensation method, the technical problem that the existing oxygen sensor currently has deviations in collected data due to differences in production processes and different operating environments and working conditions is solved, and the deviation compensation efficiency of the oxygen sensor is improved.

[0056] For example 2, please refer to Figure 2 , Figure 2 The present invention is a flow chart of an oxygen sensor deviation compensation method, comprising:

[0057] Step S201, obtaining first oxygen content data of a measured environment in a pure air environment, and second oxygen content data of the measured environment in an atmospheric pressure environment;

[0058] In the embodiment of the present invention, the air components in the environment are monitored and analyzed to obtain the oxygen content value O when the ambient air is pure. z , monitor the atmospheric pressure of the measured environment and calculate the oxygen content value O q .

[0059] Step S202, setting the difference between the first oxygen content data and the second oxygen content data as an error threshold;

[0060] In the embodiment of the present invention, the first oxygen content data O z and the second oxygen content data O q A difference operation is performed to obtain an error E1 between the two as one of the compensation conditions during operation, and the error E1 is set as the error threshold.

[0061] Step S203, obtaining the oxygen value of the oxygen sensor according to the preset first cycle;

[0062] In an optional embodiment, after step S203, the method further includes:

[0063] When the temperature of the measured environment in a pure air environment is different from the temperature of the current environment, temperature difference compensation is performed on the oxygen value.

[0064] In an embodiment of the present invention, the oxygen value of the oxygen sensor is periodically acquired with the preset first period as the period, and when the temperature of the measured environment in the pure air environment is different from the temperature of the current environment, the oxygen value is compensated for the temperature difference.

[0065] In the specific implementation, the oxygen value of the oxygen sensor is obtained in the same time period every week. When the sensor is online, the real-time collection of the oxygen sensor value needs to be compensated for the temperature difference according to the temperature difference of the environment.

[0066] Step S204, according to the preset first cycle, calculating the difference between the oxygen value currently obtained and the oxygen value obtained in the previous cycle to obtain the oxygen value deviation;

[0067] Step S205, determining whether the oxygen value deviation is greater than the error threshold; if not, determining that the currently obtained oxygen value is not abnormal data, and setting the oxygen value obtained in the previous cycle as deviation comparison data; the deviation comparison data is used to calculate the oxygen value deviation with the oxygen value obtained in the next cycle; if yes, determining that the currently obtained oxygen value is abnormal data;

[0068] In an embodiment of the present invention, when the oxygen value deviation is less than or equal to the error threshold, it is determined that the currently obtained oxygen value is not abnormal data, and when the oxygen value deviation is greater than the error threshold, it is determined that the currently obtained oxygen value is abnormal data.

[0069] In the specific implementation, the oxygen value deviation is compared with the error threshold. When the oxygen value deviation is less than or equal to the error threshold, it is determined that the currently obtained oxygen value is not abnormal data, and the sensor will not be compensated and corrected. The data of the previous cycle will continue to be retained as deviation comparison data, and compared with the data of the next cycle, and the oxygen value deviation from the oxygen value obtained in the next cycle will be calculated. When the oxygen value deviation is greater than the error threshold, compensation correction will be performed.

[0070] Step S206, based on the oxygen content data under different environments and the error threshold, compensating and correcting the oxygen value determined as abnormal data to obtain a corrected oxygen value;

[0071] In an optional embodiment, the step S206 includes:

[0072] Step S2061, calculating the oxygen content of the current environment according to the partial pressure ratio of each gas in the current environment;

[0073] Step S2062, adjusting the current environment to an atmospheric pressure environment, and calculating the oxygen content in the atmospheric pressure environment;

[0074] Step S2063, determine whether the difference between the oxygen content in the current environment and the oxygen content in the atmospheric pressure environment is greater than the error threshold; if not, set the average value of the oxygen content in the current environment and the oxygen content in the atmospheric pressure environment as the corrected oxygen value, and set the corrected oxygen value as the deviation comparison data; if so, return to execute step S206 after the second cycle.

[0075] In an embodiment of the present invention, the oxygen content of the current environment is calculated according to the partial pressure ratio of each gas in the current environment, the current environment is adjusted to an atmospheric pressure environment, and the oxygen content in the atmospheric pressure environment is calculated, and it is determined whether the difference between the oxygen content of the current environment and the oxygen content in the atmospheric pressure environment is greater than the error threshold. If not, the average value of the oxygen content of the current environment and the oxygen content in the atmospheric pressure environment is set as the corrected oxygen value, and the corrected oxygen value is set as the deviation comparison data. If yes, step S206 is re-executed after the second cycle.

[0076] In the specific implementation, the correction process is to first use the automatic ventilation system of the SF6 gas leakage online monitoring and alarm device to ventilate the measured environment to ensure that the air in the monitored environment is fresh. After 30 minutes of ventilation, the value of the oxygen sensor is continuously read while maintaining ventilation, and then compared with the error threshold. When the deviation is less than or equal to the error threshold E1, this change indicates a slight change in the oxygen content in the environment, and the sensor will not be compensated. If the deviation is still greater than the error threshold E1, the nitrogen, carbon dioxide, ozone, and VOC gases in the environment will be sampled, and the oxygen content in the current environment will be calculated based on the partial pressure ratio of each gas in the environment. z Stop ventilation in the environment to stabilize the air pressure in the environment. After continuous ventilation, the distribution of air components in the environment is basically consistent. At this time, the air pressure in the environment is tested. The relationship between the atmospheric pressure data and oxygen is relatively consistent, and the oxygen value O in the environment is calculated. q Relatively accurate. Calculate O z With O q Whether the difference is within the error threshold E1 range, within the error range, the oxygen content calculated by the component is compared with the oxygen content at atmospheric pressure to obtain the average value for compensation correction, and the current data of the oxygen sensor is recorded as the reference data for the next comparison cycle. If it exceeds the error threshold E1 range, the compensation will be abandoned and the compensation process will be repeated after 24 hours.

The oxygen sensor in the figure is an oxygen sensor that has been online for more than 1 year. It can be seen from the curve that the oxygen sensor has shown obvious nonlinear attenuation, and the final output values ​​of the oxygen sensor after comprehensive compensation are all within the standard oxygen content range.

The oxygen value after each compensation is compared with the measured value of the standard oxygen content meter. The data results are basically consistent, and the error is controlled at <±1%, which has fully met the use requirements of the SF6 gas leakage online monitoring and alarm device.
