Description

Technical Field

[0001] The present invention relates to the field of automatic control technology, and in particular to a calibration method, device, equipment and medium for a gas probe. Background Art

[0002] In the field of nuclear power, high-purity hydrogen or oxygen, as well as other purified gases, are often needed. As for hydrogen or oxygen, due to their relatively active chemical properties, once they leak during transportation or use, they are usually colorless and odorless, which can easily lead to catastrophic consequences. Therefore, in order to ensure the safe operation of nuclear power facilities, gas alarm detectors have become an indispensable monitoring device in nuclear power plants.

[0003] The main function of the gas alarm detector is to monitor the gas concentration in the surrounding environment in real time. Once the gas concentration exceeds the preset safety threshold, an alarm will be issued immediately to remind the operator to take timely measures. In order to ensure the accuracy and reliability of the gas alarm detector, it must be regularly calibrated for sensitivity to ensure that it can respond quickly and accurately to changes in gas concentration. At present, most calibration processes still rely on manual operation, which is not only inefficient, but also easily affected by human factors, resulting in inaccurate calibration results. At the same time, the lack of automated calibration instruments and working methods also limits the convenience and flexibility of calibration, and cannot meet the needs of nuclear power plants for efficient and accurate calibration of gas alarm detectors.

[0004] Therefore, how to automatically classify and calibrate gas probes and improve the calibration efficiency of gas probes has become an urgent problem to be solved. Summary of the invention

When the real-time environmental parameters are different from the initial environmental parameters, the initial environmental parameters are updated according to the real-time environmental parameters. After the calibration in the target calibration mode is completed, the update module returns to execute the step of analyzing the initial environmental parameters and the gas parameters until the calibration of the probe to be calibrated is completed.

[0009] In a fourth aspect, an embodiment of the present invention provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the gas probe calibration method of the first aspect is implemented.

[0010] The beneficial effects of the embodiments of the present invention compared with the prior art are as follows: the present invention matches the gas parameters of the corresponding calibration gas according to the probe parameters of the probe to be calibrated, analyzes the initial environmental parameters and the gas parameters, determines the target calibration mode, determines the target control parameters according to the target calibration mode, determines the target parameter values ​​of the corresponding target control parameters according to the probe parameters, the initial environmental parameters and the gas parameters, controls the calibration gas to flow to the probe to be calibrated according to the target parameter values ​​of the corresponding target control parameters under the calibration environment, calibrates the probe to be calibrated under the target calibration mode, monitors the real-time environmental parameters of the calibration environment, and updates the initial environmental parameters according to the real-time environmental parameters when the real-time environmental parameters are different from the initial environmental parameters; after the calibration under the target calibration mode is completed, returns to the step of analyzing the initial environmental parameters and the gas parameters until the calibration is completed.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] like Figure 1 FIG. 1 is a flow chart of a gas probe calibration method provided in Embodiment 1 of the present invention, comprising the following steps: Step S101: Acquire probe parameters of the probe to be calibrated and initial environmental parameters of the calibration environment, and match gas parameters of the corresponding calibration gas from a gas database according to the probe parameters.

[0016] In this embodiment, the probe to be calibrated may refer to a gas detection head to be calibrated, and the probe parameters may refer to parameters related to the probe to be calibrated, which may include physical parameters and state parameters of the probe to be calibrated, wherein the physical parameters may include the type of gas monitored and alarmed by the probe to be calibrated, such as hydrogen, methane and oxygen, and the state parameters may include the service life and degree of damage of the probe to be calibrated; the calibration environment may refer to the physical space in which the probe to be calibrated is calibrated, and the initial environmental parameters may refer to parameters related to the calibration environment, which may include the temperature, humidity and air pressure of the calibration environment; the calibration gas may refer to a gas corresponding to the type of gas monitored and alarmed by the probe to be calibrated, and the gas parameters may refer to parameters related to the calibration gas, which may include the gas type, density, toxicity and diffusion coefficient of the gas to be calibrated; the gas database may be used to store the mapping relationship between gas types and corresponding gas parameters.

[0017] Specifically, the probe parameters of the probe to be calibrated and the initial environmental parameters of the calibration environment are obtained, and the gas type monitored and alarmed by the probe to be calibrated is determined based on the probe parameters. Based on the gas type, the gas parameters of the corresponding calibration gas are matched from the gas database.

[0018] Step S102: Analyze the initial environmental parameters and gas parameters, determine the target calibration mode for calibrating the probe to be calibrated, and determine the target control parameters for calibrating the probe to be calibrated according to the target calibration mode.

[0019] In this embodiment, the target calibration mode may refer to the method or process used to calibrate the probe to be calibrated, which may include a flow mode and a time mode. The method used in the flow mode may be to continuously output the calibration gas at a certain flow rate, and the flow rate may be variable or constant until the total flow rate threshold is reached, and the calibration in the flow mode is terminated. The flow mode is more suitable for calibrating the sensitivity of the gas probe to gas environments with different flow rates; the method used in the time mode may be to continuously output the calibration gas at a constant flow rate, such as 1L / s, and after the total time threshold is outputted at a constant rate, such as 1 minute, the calibration in the time mode is terminated. The time mode is more suitable for calibrating the response capability of the gas probe in a stable gas environment; The target control parameter may refer to a parameter that needs to be precisely controlled during the calibration process. If the target calibration mode is a flow mode, the target control parameter corresponding to the flow mode may include the flow rate of the output calibration gas and the total flow rate of the calibration gas flowing through the probe to be calibrated. If the target calibration mode is a time mode, the target control parameter corresponding to the time mode may include the flow rate of the output calibration gas and the total time of the calibration gas flowing through the probe to be calibrated. The target parameter value may refer to the specific numerical value of the corresponding target control parameter.

[0020] Specifically, the gas parameters are analyzed to determine the initial calibration mode for calibrating the probe to be calibrated, the initial calibration mode is adjusted according to the initial environmental parameters to obtain the target calibration mode, and the target control parameters corresponding to the target calibration mode are determined according to the target calibration mode. The probe parameters, initial environmental parameters and gas parameters are analyzed to determine the target parameter values ​​that need to be set for the corresponding target control parameters.

[0021] Step S103: Determine the target parameter value of the corresponding target control parameter according to the probe parameters, initial environment parameters and gas parameters. Under the verification environment, control the verification gas flow to the probe to be verified according to the target parameter value of the corresponding target control parameter, so as to verify the probe to be verified in the target verification mode.

[0022] Specifically, in a calibration environment, using a target calibration mode method, according to the parameter value of the corresponding target control parameter, the calibration gas is controlled to flow to the probe to be calibrated, the response capability of the probe to be calibrated is observed, and the sensitivity and other indicators of the probe to be calibrated are calibrated.

[0023] Optionally, the calibration method of the present invention can be used to control a hardware system for calibrating a probe to be calibrated, which is composed of hardware devices such as a solenoid valve, a pressure reducing valve, a mass flow controller, and connected pipes, wherein the mass flow controller is a finished machine that can automatically adjust the gas flow rate. Then, according to the parameter value of the corresponding target control parameter, the calibration gas is controlled to flow to the probe to be calibrated. The specific process of calibrating the probe to be calibrated in the target calibration mode can be: 1) Open the solenoid valve in the pipeline connected to the calibration gas to allow the calibration gas to flow into the calibration environment; 2) When it is detected that the calibration gas flows to the mass flow controller, if the target calibration mode is the flow mode, the mass flow controller is controlled to make the calibration gas flow to the probe to be calibrated according to the flow rate of the output calibration gas (variable or constant), and the mass flow controller counts the cumulative flow of the calibration gas flowing through the probe to be calibrated. When the cumulative flow is equal to the total flow threshold, the calibration in this flow mode is terminated; 3) When it is detected that the calibration gas flows to the mass flow controller, if the target calibration mode is the time mode, the mass flow controller is controlled to make the calibration gas flow to the probe to be calibrated according to the flow rate of the output calibration gas (constant), and the mass flow controller counts the cumulative time of the calibration gas flowing through the probe to be calibrated. When the cumulative time is equal to the total time threshold, the calibration in this time mode is terminated.

[0024] Step S104: Monitor the real-time environmental parameters of the calibration environment. When the real-time environmental parameters are different from the initial environmental parameters, update the initial environmental parameters according to the real-time environmental parameters. After the calibration in the target calibration mode is completed, return to the step of analyzing the initial environmental parameters and gas parameters until the calibration of the probe to be calibrated is completed.

[0025] In this embodiment, the real-time environmental parameter may refer to an environmental parameter of a calibration environment during the calibration of the probe to be calibrated.

[0026] Specifically, during the verification process, the real-time environmental parameters of the verification environment are monitored, and the real-time environmental parameters are compared with the initial environmental parameters. Based on the comparison results, the initial environmental parameters are updated to obtain new initial environmental parameters. After the verification in the target verification mode is completed, the content of the above step S102 is executed according to the new initial environmental parameters until the verification termination conditions are met, such as receiving an instruction to terminate the verification, etc., to end the verification of the probe to be verified.

[0027] Optionally, after monitoring the real-time environmental parameters of the verification environment, if the air pressure value of the verification environment is monitored to be lower than the preset pressure range, a low pressure warning prompt is issued; if the air pressure value of the verification environment is monitored to be higher than the preset pressure range, a high pressure warning prompt is issued.

[0028] In this embodiment, it is automatically realized to determine the target verification mode and the target parameter values ​​of the corresponding target control parameters that are more in line with the actual needs and conditions of the verification according to the probe parameters, gas parameters and initial environmental parameters. Therefore, when the verification gas is controlled to calibrate the probe to be verified according to the determined target verification mode and the target parameter values ​​of the corresponding target control parameters, the verification efficiency is improved while the accuracy of the verification is also improved. During the verification process, the target verification mode is dynamically adjusted according to the real-time environmental parameters monitored, thereby enhancing the flexibility and adaptability of the verification and improving the verification efficiency.

[0029] like Figure 2 As shown, it is a flow chart of a gas probe calibration method provided in the second embodiment of the present invention. In the above step S102, the initial environmental parameters and gas parameters are analyzed to determine the calibration mode for the probe to be calibrated. According to the target calibration mode, the target control parameters for calibrating the probe to be calibrated are determined, which may include the following steps: Step S201: Determine the gas type of the calibration gas from the gas parameters, and determine the initial calibration mode according to the gas type.

[0030] Step S202: According to the initial environmental parameters, the initial verification mode is adjusted to obtain the target verification mode, and according to the target verification mode, the target control parameters are matched from the parameter database.

[0031] In this embodiment, the initial calibration mode may refer to a method or process used to calibrate the probe to be calibrated, which is determined according to the gas type of the calibration gas, and the parameter database is used to store the mapping relationship between the target calibration mode and the target control parameters.

[0032] Specifically, the initial calibration mode may be determined from a gas-mode mapping table according to the gas type of the calibration gas, and the gas-mode mapping table may be used to store a mapping relationship between the gas type and the initial calibration mode; For example, if the gas type monitored and alarmed by the probe to be calibrated is relatively stable gas such as oxygen and nitrogen, whose concentration usually does not change much under normal environment, then the probe to be calibrated needs to be calibrated for its response ability under stable gas environment. Then, the preferred initial calibration mode can be determined as time mode from the gas-mode mapping table; If the gas type monitored and alarmed by the probe to be calibrated is a relatively unstable gas such as methane, which is toxic or flammable and explosive, and the changes in its concentration and flow rate may pose a threat to safety, then the probe to be calibrated needs to be calibrated for its sensitivity in different flow rate gas environments. In this case, the preferred initial calibration mode can be determined as the flow mode from the gas-mode mapping table; After the initial calibration mode is determined, if the initial environmental parameters such as the temperature and air pressure of the calibration environment affect the diffusion characteristics of the gas and thus affect the applicability of the calibration mode, the initial calibration mode may be adjusted to obtain the target calibration mode; For example, if the gas type is methane, the diffusion rate of methane may be accelerated in a low-pressure environment, and the diffusion rate may be slowed down in a high-pressure environment. The initial calibration mode of methane is the flow mode. If the calibration environment is in a low-pressure environment, the probe needs to respond more sensitively to rapidly changing gas concentrations. Therefore, in this case, the flow mode is still appropriate because it can simulate the rapidly changing gas flow conditions in the actual working environment. If the calibration environment is in a high-pressure environment, the diffusion rate of methane slows down and the gas flow is relatively stable. At this time, if the flow mode is continued to be used for calibration, the sensitivity of the probe may not be accurately evaluated because the gas flow rate is too slow. Therefore, in this case, the flow mode can be adjusted to the time mode.

[0033] In this embodiment, the verification mode is determined and adjusted by comprehensively considering the gas type and initial environmental parameters of the verification gas, and finally the target verification mode and the corresponding target control parameters are obtained, so that the determined target verification mode is consistent with the characteristics of the verification gas and adapts to the actual verification environment, thereby improving the accuracy and efficiency of the verification and enhancing the reliability and adaptability of the verification results.

[0034] like Figure 3 As shown, it is a flow chart of a gas probe calibration method provided in Embodiment 3 of the present invention. In the above step S103, according to the probe parameters, the initial environment parameters and the gas parameters, the target parameter value corresponding to the target control parameter is determined, which may include the following steps: Step S301: for any target control parameter, determine the parameter value range of the target control parameter according to the initial environment parameters and the gas parameters.

[0035] Step S302: Determine a target parameter value of a target control parameter from a parameter value range according to the probe parameter.

[0036] Specifically, according to the initial environmental parameters and gas parameters, a parameter-parameter value mapping table is queried to determine the parameter value range of the target control parameter, the parameter-parameter value mapping table is used to store the mapping relationship between the initial environmental parameters, the gas parameters and the parameter value range of the target control parameter, the service life and the degree of damage parameters of the probe to be calibrated are determined from the probe parameters, the weighted sum operation is performed on the service life and the degree of damage parameters to obtain the probe compensation coefficient, the probe compensation coefficient is positively correlated with the service life and the degree of damage of the probe to be calibrated, the middle value in the parameter value range is determined, if the probe compensation coefficient exceeds the threshold value, then the parameter value above the middle value in the parameter value range is selected as the target parameter value, the reason is that if The larger the probe compensation coefficient is, the lower the current performance of the probe to be calibrated is. Therefore, it is necessary to select a higher target parameter value (such as selecting a faster flow rate to output the calibration gas, selecting a larger total gas flow rate flowing through the probe to be calibrated in the flow mode (a larger total flow rate threshold), and selecting a larger total gas time flowing through the probe to be calibrated in the time mode (a larger total time threshold)) to ensure that the probe to be calibrated can be calibrated even when the performance is low. If the probe compensation coefficient does not exceed the threshold, the parameter value below the middle value within the parameter value range is selected as the target parameter value. The reason is that the smaller the probe compensation coefficient is, the higher the current performance of the probe to be calibrated is. Therefore, a lower target parameter value is selected to calibrate the probe to be calibrated.

[0037] In this embodiment, for any target control parameter, by comprehensively considering the initial environmental parameters, gas parameters and probe parameters (including the age and degree of damage), the determined target parameter value not only integrates the influence of the calibration environment and gas characteristics, but also adapts to the current state of the probe itself, thereby improving the accuracy and efficiency of the calibration, while enhancing the reliability and adaptability of the calibration results.

[0038] like Figure 4 As shown, it is a flow chart of a gas probe calibration method provided in the fourth embodiment of the present invention. In the above step S103, under the initial calibration environment, according to the target parameter value of the corresponding target control parameter, the calibration gas is controlled to flow to the probe to be calibrated, so as to calibrate the probe to be calibrated in the target calibration mode, which may include the following steps: Step S401: If the target calibration mode is the flow mode, the cumulative flow of the calibration gas flowing through the probe to be calibrated is counted.

[0039] Step S402: If the accumulated flow is equal to the total flow threshold, the verification in the flow mode is terminated.

[0040] In this embodiment, the cumulative flow rate may refer to the total flow rate of the calibration gas flowing through the probe to be calibrated, and the total flow rate threshold may refer to the target parameter value of the target control parameter, which is the total flow rate of the calibration gas flowing through the probe to be calibrated under the flow mode. The determination of the total flow rate threshold may refer to the above-mentioned step S103, or the contents of step S301 to step S302.

[0041] Specifically, if the target calibration mode is a flow mode, the target control parameters corresponding to the flow mode may include the flow rate of the output calibration gas and the total flow rate of the calibration gas flowing through the probe to be calibrated. Under the initial calibration environment, the calibration gas is controlled to flow to the probe to be calibrated according to the specific flow rate value of the calibration gas (variable or constant), and the total flow rate of the calibration gas flowing through the probe to be calibrated is counted. If the accumulated flow rate is equal to the total flow threshold, the calibration under the flow mode is terminated.

[0042] In this embodiment, if the target calibration mode is a flow mode, the calibration is terminated by outputting the calibration gas at a variable or constant flow rate until the accumulated flow reaches the total flow threshold. This enables precise control of the gas exposure and flow state during the calibration process, thereby ensuring the adequacy and standardization of the calibration, helping to evaluate the sensitivity of the gas probe in different flow rate environments, and improving the accuracy and reliability of the calibration results.

[0043] like Figure 5 As shown, it is a flow chart of a gas probe calibration method provided in Embodiment 5 of the present invention. In the above step S103, under the initial calibration environment, according to the target parameter value of the corresponding target control parameter, the calibration gas is controlled to flow to the probe to be calibrated, so as to calibrate the probe to be calibrated in the target calibration mode. The following steps may also be included: Step S501: If the calibration mode is the time mode, the cumulative time of the calibration gas flowing through the probe to be calibrated is counted.

[0044] Step S502: If the accumulated time is equal to the total time threshold, the verification in the time mode is terminated.

[0045] In this embodiment, the accumulated time may refer to the total time of the calibration gas flowing through the probe to be calibrated, and the total time threshold may refer to the target parameter value of the target control parameter, which is the total time of the calibration gas flowing through the probe to be calibrated in the time mode. The determination of the total time threshold may refer to the above-mentioned step S103, or the contents of step S301 to step S302.

[0046] Specifically, if the target verification mode is the time mode, the target control parameters corresponding to the time mode may include the flow rate of the output verification gas and the total time of the verification gas flowing through the probe to be verified. Under the initial verification environment, the verification gas is controlled to flow to the probe to be verified according to the specific flow rate value of the verification gas, and the cumulative time of the verification gas flowing through the probe to be verified is counted. If the cumulative time is equal to the total time threshold, the verification in the time mode is ended.

[0047] In this embodiment, if the target calibration mode is the time mode, the calibration is ended by outputting the calibration gas at a constant flow rate and continuing for a total time threshold. The flow rate and flow time of the gas during the calibration process can be accurately controlled, thereby ensuring the adequacy and standardization of the calibration, helping to evaluate the response speed and stability of the gas probe in a stable gas environment, and improving the accuracy and reliability of the calibration results.

[0048] like Figure 6 As shown, it is a flow chart of a gas probe calibration method provided in Embodiment 6 of the present invention. In the above step S104, when the real-time environmental parameters are different from the initial environmental parameters, the initial environmental parameters are updated according to the real-time environmental parameters. After the calibration in the target calibration mode is completed, the step of analyzing the initial environmental parameters and the gas parameters is returned to execute until the calibration of the probe to be calibrated is completed. The following steps may be included: Step S601: perform consistency comparison between the real-time environment parameters and the initial environment parameters to obtain a comparison result.

[0049] Step S602: If the comparison result does not meet the preset conditions, the initial environmental parameters are updated according to the real-time environmental parameters. After the verification in the target verification mode is completed, the process returns to the step of analyzing the initial environmental parameters and gas parameters until the verification of the probe to be verified is completed.

[0050] In this embodiment, the comparison result may refer to the result of comparing the real-time environment parameters with the initial environment parameters, and the preset condition may refer to the pre-set condition required to update the initial environment parameters.

[0051] Specifically, the real-time environmental parameters can be compared with the values ​​of the corresponding initial environmental parameters. The comparison can be performed by performing difference calculation, etc. to obtain a comparison result. If the comparison result shows that the difference between the values ​​of the real-time environmental parameters and the corresponding initial environmental parameters exceeds a threshold, it is determined that the comparison result does not meet the preset conditions, and the real-time environmental parameters are used as new initial environmental parameters. After the verification in the target verification mode is completed, the process returns to execute the content in the above step S102 until the verification is completed.

[0052] In the process of taking the real-time environmental parameters as new initial environmental parameters and returning to execute the contents in the above step S102, since the real-time environmental parameters are taken as new initial environmental parameters, when analyzing the new initial environmental parameters and gas parameters to determine the target calibration mode for calibrating the probe to be calibrated, the target calibration mode may be switched due to the update of the initial environmental parameters. For example, if the calibration gas is methane, under the initial environmental parameters, the calibration environment is a low-pressure environment, and the target calibration mode of methane is a flow mode, then in the process of using methane to calibrate the probe to be calibrated according to the flow mode, due to continuous gas input, the air pressure of the calibration environment will gradually increase under the monitored real-time environmental parameters. When the high-pressure environment is reached, the target calibration mode can be switched from the flow mode to the time mode when analyzing the air pressure according to the new initial environmental parameters.

[0053] In this embodiment, by comparing the real-time environmental parameters with the initial environmental parameters and dynamically adjusting the initial environmental parameters accordingly, the target verification mode is switched, which can flexibly adapt to the actual changes in environmental conditions during the verification process, thereby improving the flexibility and adaptability of the verification and also improving the verification efficiency.

[0054] like Figure 7 As shown, a gas probe calibration device provided in Embodiment 7 of the present invention corresponds to the gas probe calibration method in the above embodiment. The gas probe calibration device includes an acquisition module 71, a mode determination module 72, a calibration module 73 and an update module 74. The functional modules are described in detail as follows: An acquisition module 71 is used to acquire probe parameters of the probe to be calibrated and initial environmental parameters of the calibration environment, and match gas parameters of the corresponding calibration gas from a gas database according to the probe parameters; A mode determination module 72 is used to analyze the initial environmental parameters and the gas parameters, determine a target calibration mode for calibrating the probe to be calibrated, and determine a target control parameter for calibrating the probe to be calibrated according to the target calibration mode, wherein the target calibration mode includes a flow mode and a time mode; The calibration module 73 is used to determine the target parameter value of the corresponding target control parameter according to the probe parameter, the initial environment parameter and the gas parameter, and control the calibration gas to flow to the probe to be calibrated according to the target parameter value of the corresponding target control parameter under the calibration environment, so as to calibrate the probe to be calibrated in the target calibration mode; The update module 74 is used to monitor the real-time environmental parameters of the calibration environment. When the real-time environmental parameters are different from the initial environmental parameters, the initial environmental parameters are updated according to the real-time environmental parameters. After the calibration in the target calibration mode is completed, the update module returns to execute the step of analyzing the initial environmental parameters and the gas parameters until the calibration of the probe to be calibrated is completed.

[0055] Optionally, the mode determination module 72 includes: an initial determination unit, configured to determine a gas type of the calibration gas from the gas parameters, and determine an initial calibration mode according to the gas type; An adjustment unit is used to adjust the initial verification mode according to the initial environmental parameters to obtain the target verification mode, and match the target control parameters from a parameter database according to the target verification mode.
