Abstract
Description
Technical Field
[0001] The present invention relates to the field of optical detection, and in particular to a testing method for a radon gas detector and related equipment. Background Art
[0002] Radon is a radioactive rare gas, typically released in nature by the decay of radium and uranium in soil and rocks. To detect radon concentrations in an environment, a radon detector generates an electrical signal by detecting radon alpha particles. The signal's peak value and waveform are then used to determine the radon concentration.
[0003] In the prior art, radon detectors are usually tested through a radon chamber. A radon chamber is a device that simulates a real environment to test the performance of radon sensors by controlling parameters such as radon concentration, temperature and humidity. Radium or uranium or their isotopes are used as radon sources to produce radon gas, resulting in high testing costs for radon detectors, such as high risk of radioactive substances, high costs for building and maintaining radon chambers, and high time costs for adjusting radon concentrations. Summary of the Invention
[0004] In response to the above problems, the embodiments of the present application provide a radon gas detector testing method and related equipment. The adoption of the solution of the present application is conducive to solving the problem of high detection costs of radon gas detectors.
[0005] In a first aspect, an embodiment of the present application provides a method for testing a radon detector, which is applied to a test device for a radon detector. The test device for the radon detector includes an americium-241 radioactive source and a signal transceiver module. The americium-241 radioactive source is used to generate alpha particles. The signal transceiver module is used to collect signal data generated when the radon detector is running or to send a signal to the radon detector. The method includes: obtaining device parameters of the radon detector to be tested, and determining a first test concentration of the radon detector to be tested according to the device parameters; and determining a first test concentration of the radon detector to be tested according to the first test concentration. The test concentration determines the test distance of the radon detector under test, and the first test concentration is negatively correlated with the test distance; the distance between the americium-241 radioactive source and the radon detector under test is controlled to meet the test distance, and the americium-241 radioactive source is controlled to be turned on; a plurality of first test data collected by the signal transceiver module from the radon detector under test during the period when the americium-241 radioactive source is turned on are obtained, the first test data being electrical signal data corresponding to alpha particles generated by the americium-241 radioactive source; and a test result of the radon detector under test is determined based on the plurality of first test data.
[0006] It can be seen that in the embodiment of the present application, the test results of the radon gas detector under test are determined by obtaining multiple first test data, and the replacement of the traditional radon source with the americium 241 radioactive source in the test of the radon gas detector is realized, thereby solving the problems of high detection costs of radon gas detectors such as high danger caused by traditional radon sources, high costs for radon chamber construction and maintenance, and long radon concentration adjustment time during the test process of the radon gas detector.
[0007] In combination with the first aspect, in a possible embodiment, before determining the test distance of the radon detector under test according to the first test concentration, the method further includes: controlling the americium 241 radioactive source to adjust the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance; obtaining alarm information collected from the radon detector under test by the signal transceiver module during the process of adjusting the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance; if the alarm information collected from the radon detector under test by the signal transceiver module is obtained during the process of adjusting the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance, then determining the trigger distance between the americium 241 radioactive source and the radon detector under test when the radon detector under test generates the alarm information according to the collection time of the alarm information; determining the alarm trigger concentration of the radon detector under test according to the trigger distance; if the alarm trigger concentration is not greater than the first test concentration, the method further includes: determining that the test result of the radon detector under test is a test pass.
[0008] It can be seen that in the embodiment of the present application, the radon detector under test of the threshold alarm type is tested by using the alarm information and related data obtained in the process of adjusting the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance. When the alarm information obtained by the test equipment is successful, the test result of the radon detector under test can be determined based on the alarm information and related signals, and there is no need to execute subsequent steps, thereby improving the test efficiency.
[0009] In combination with the first aspect, in a possible embodiment, before controlling the americium 241 radioactive source to adjust the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance, the method also includes: determining the alarm type of the radon detector under test, the alarm type including a threshold alarm type or a data feature alarm type; if the alarm type of the radon detector under test is a data feature alarm type, the method also includes: generating alarm information of the radon detector under test according to the first test concentration, the alarm information is used to simulate the radon environment of the first test concentration; controlling the signal transceiver module to send the alarm information to the radon detector under test; if the alarm information is not received, the test result of the radon detector under test is determined as a test failure.
[0010] It can be seen that in the embodiment of the present application, an alarm message is sent to the radon detector under test through the signal transceiver module, and the radon detector under test is tested. If the alarm message generated by the radon detector under test cannot be obtained, the test result of the radon detector under test is determined to be a test failure, and there is no need to execute subsequent steps of testing according to the test distance, thereby improving the test efficiency.
[0011] In combination with the first aspect, in a possible embodiment, the test distance of the radon detector under test is determined according to the first test concentration, including: determining the minimum alarm concentration of the radon detector under test according to the first test concentration; determining the adaptation scene of the radon detector under test according to the equipment parameters, the adaptation scene including the indoor scene, the outdoor scene or the underground scene; obtaining the temperature parameter and the humidity parameter corresponding to the adaptation scene according to the adaptation scene; wherein the temperature parameter characterizes the degree of influence of the temperature in the adaptation scene on the radon concentration, and the humidity parameter characterizes the degree of influence of the humidity in the adaptation scene on the radon concentration; the second test concentration is calculated according to the minimum alarm concentration, the temperature parameter and the humidity parameter; and the test distance is determined according to the corresponding relationship between the second test concentration and the preset test concentration and the distance.
[0012] As can be seen, in this embodiment of the application, by integrating scenario-based environmental parameters, the test distance used for testing is adjusted based on the impact of different usage scenarios of the radon detector on radon concentration. This optimizes the test parameters and takes into account the impact of environmental factors in different adaptation scenarios on radon concentration. This provides a more realistic test environment for the radon detector under test and improves the credibility of the test results.
[0013] In combination with the first aspect, in a possible embodiment, the test result of the radon gas detector under test is determined based on multiple first test data, including: judging whether the values of the multiple first test data are in a preset value range corresponding to americium 241; if the values of the multiple first test data are all in the preset value range, then determining that the test result of the radon gas detector under test is a passed test; if the values of the multiple first test data are not all in the preset value range, then determining that the test result of the radon gas detector under test is a failed test.
[0014] It can be seen that in the embodiment of the present application, by judging whether multiple first test data are in a preset numerical range, it can be determined whether the test function of the radon gas detector under test for alpha particles produced by the decay of americium 241 is qualified. On the premise that the test function of the radon gas detector under test for alpha particles produced by the decay of americium 241 is qualified, the test result of the radon gas detector under test can be determined as a passed test, thereby realizing the automated testing of radon gas detectors based on americium 241 and improving the test efficiency.
[0015] In combination with the first aspect, in a possible embodiment, before determining whether the values of the plurality of first test data are within a preset value range, the method further includes: determining the first test data among the plurality of first test data that is lower than the first preset value as invalid data.
[0016] It can be seen that in the embodiment of the present application, the first preset value is used to filter the multiple first test data, and the data that does not meet the alpha particle energy is determined as invalid data, which reduces the data processing volume of the test equipment and thus improves the processing efficiency of the test equipment.
[0017] In combination with the first aspect, in a possible embodiment, the method also includes: obtaining a plurality of second test data obtained by the signal transceiver module from the radon gas detector under test within a preset time, the second test data being the dark current signal data generated by the radon gas detector under test; if the sum of the plurality of second test data is greater than a second preset value, it is determined that the test result of the radon gas detector under test is a test failure.
[0018] It can be seen that in the embodiment of the present application, multiple second test data of the radon detector under test are obtained through the test equipment of the radon detector, and the dark current situation of the radon detector under test can be judged first. If the dark current fluctuation of the radon detector under test is large, the test result of the radon detector under test is directly determined to be a test failure, and there is no need to perform subsequent steps, which improves the test efficiency.
[0019] In a second aspect, an embodiment of the present application further provides a radon detector test device. The radon detector test device includes an americium-241 radioactive source and a signal transceiver module. The americium-241 radioactive source is used to generate alpha particles.

DETAILED DESCRIPTION
[0041] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 this application.

[0043] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0044] The embodiments of the present application are described below with reference to the accompanying drawings.
[0045] Example 1: Please see Figure 1 , Figure 1 This is a schematic diagram of an application scenario of a radon detector testing method provided in an embodiment of the present application. The application scenario 100 includes a testing device 101, a radon detector to be tested 102, and a terminal device 103.
[0046] Test device 101 is a radon detector tester, comprising an americium-241 radiation source 1011 and a signal transceiver module 1012. Americium-241 radiation source 1011 contains americium-241, which has a half-life of approximately 432.2 years and is a relatively safe and readily available alpha radiation source. The primary energy of the alpha radiation is 5.48 MeV, which has weak penetrating power and also emits a small amount of gamma rays. Americium-241 radiation source 1011 is used to simulate radon gas to enable radon detector detection.
[0047] The signal transceiver module 1012 is used to connect to the radon detector 102 under test and obtain signal data from the radon detector 102 under test or send signals to the radon detector 102 under test.
[0048] The terminal device 103 is used to connect to the test device 101 and send device parameters to the test device 101 or obtain test results.
[0049] In the embodiment of the present application, after the radon detector 102 to be tested is placed on the testing device 101, the testing device 101 obtains the device parameters of the radon detector 102 to be tested, and determines the first test concentration of the radon detector 102 to be tested according to the device parameters.
[0050] The first test concentration is determined by the test device 101 based on the device parameters of the radon detector 102 being tested, and is a radon concentration that can trigger an alarm in the radon detector 102 being tested.
[0051] The testing device 101 determines the testing distance of the radon detector 102 according to the first testing concentration. The first testing concentration is negatively correlated with the testing distance. That is, the higher the first testing concentration, the shorter the testing distance, and the lower the first testing concentration, the longer the testing distance.
[0052] The testing device 101 controls the distance between the americium 241 radiation source 1011 and the radon detector 102 to meet the testing distance, and controls the americium 241 radiation source 1011 to be turned on.
[0053] The test device 101 obtains a plurality of first test data collected by the signal transceiver module from the radon detector 102 under test when the americium 241 radiation source 1011 is turned on. The first test data is the electrical signal data corresponding to the α particles generated by the americium 241 radiation source 1011 .
[0054] The plurality of first test data herein include electrical signals generated by alpha particles generated by the decay of americium 241 and received by the radon detector 102 when the americium 241 radiation source 1011 is turned on.
[0055] The testing device 101 determines a test result of the radon detector 102 according to the plurality of first test data.
[0056] The testing device 101 determines the test result of the radon detector 102 under test based on the data features or values of the plurality of first test data, specifically based on whether the plurality of first test data conforms to the data features corresponding to the α particles generated by americium 241 .
[0057] It can be seen that in the embodiment of the present application, the test results of the radon gas detector under test are determined by obtaining multiple first test data, and the replacement of the traditional radon source with the americium 241 radioactive source in the test of the radon gas detector is realized, thereby solving the problems of high detection costs of radon gas detectors such as high danger caused by traditional radon sources, high costs for radon chamber construction and maintenance, and long radon concentration adjustment time during the test process of the radon gas detector.
[0058] The following is a description of the specific steps, see Figure 2 , Figure 2 A flowchart of a method for testing a radon gas detector provided in an embodiment of the present application includes steps S201-S205.
[0059] S201: The testing device obtains device parameters of the radon gas detector under test, and determines a first test concentration of the radon gas detector under test according to the device parameters.
[0060] Specifically, the device parameters include the detection concentration range (e.g., 200Bq / m³-400Bq / m³) or alarm concentration (e.g., 200Bq / m³) of the radon detector being tested, and can be obtained based on the device type and model of the radon detector being tested.
[0061] Optionally, the method also includes: obtaining a plurality of second test data obtained by the signal transceiver module from the radon gas detector under test within a preset time, the second test data being dark current signal data generated by the radon gas detector under test; if the sum of the plurality of second test data is greater than a second preset value, determining that the test result of the radon gas detector under test is a test failure.
[0062] Specifically, since alpha particles generate pA-level current in the radon detector under test, if the dark current of the sensor fluctuates greatly, it will affect the accuracy of the data. Therefore, before testing the radon detection performance of the radon detector under test, the dark current of the radon detector under test also needs to be tested.
[0063] Before obtaining the device parameters of the radon detector under test, the test equipment can also collect multiple second test data obtained from the radon detector under test within a preset time through the signal transceiver module. The multiple second test data here specifically include multiple current data collected under the same voltage (such as 20mv). The multiple second test data are used to characterize the dark current fluctuation of the radon detector under test.
[0064] The testing device determines the dark current of the radon detector under test based on data characteristics of the plurality of second test data, such as the mean and standard deviation of the plurality of second test data. In the embodiment of the present application, if the sum of the plurality of second test data is greater than a second preset value, it is determined that the dark current of the radon detector under test has large fluctuations, and the test result of the radon detector under test is a failure.
[0065] It can be seen that in the embodiment of the present application, multiple second test data of the radon detector under test are obtained through the test equipment of the radon detector, and the dark current situation of the radon detector under test can be judged first. If the dark current fluctuation of the radon detector under test is large, the test result of the radon detector under test is directly determined to be a test failure, and there is no need to perform subsequent steps, which improves the test efficiency.
[0066] S202: The testing device determines a test distance of the radon detector to be tested according to a first test concentration, where the first test concentration is negatively correlated with the test distance.
[0067] The test distance here is determined according to the correspondence between the preset test concentration and the test distance. For any value in the detection concentration range of the radon detector being tested, the subsequent test equipment adjusts the distance test between the americium 241 radioactive source and the radon detector being tested to the test distance to simulate the radon environment of the test concentration.
[0068] Optionally, determining the test distance of the radon detector under test according to the first test concentration includes: determining the minimum alarm concentration of the radon detector under test according to the first test concentration; determining the adaptation scene of the radon detector under test according to the device parameters, the adaptation scene including the indoor scene, the outdoor scene or the underground scene; obtaining the temperature parameter and the humidity parameter corresponding to the adaptation scene according to the adaptation scene; wherein the temperature parameter characterizes the degree of influence of the temperature in the adaptation scene on the radon concentration, and the humidity parameter characterizes the degree of influence of the humidity in the adaptation scene on the radon concentration; calculating the second test concentration according to the minimum alarm concentration, the temperature parameter and the humidity parameter; and determining the test distance according to the corresponding relationship between the second test concentration and the preset test concentration and distance.
[0069] Specifically, it should be noted that temperature and humidity can affect the actual concentration of radon gas and may also cause radon detectors to detect different results in the same environment and at the same concentration. Different temperature and humidity levels may cause radon detectors to detect different values in the same environment and at the same concentration.
[0070] If the radon gas in the environment reaches the target concentration, but the radon gas detector cannot detect the correct concentration value due to the influence of the environment's temperature and humidity, and thus the radon gas detector cannot alarm in time, therefore, in an embodiment of the present application, the test concentration is corrected through a dynamic environmental compensation mechanism, thereby simulating a more realistic test environment through an americium 241 radioactive source.
[0071] The testing device first determines the minimum alarm concentration of the radon detector under test according to the first test concentration. When the radon detector under test detects that the radon concentration in the environment is the minimum alarm concentration, the radon detector under test will alarm.
[0072] The device's compatible scenarios are determined based on the device's parameters. These scenarios include indoor, outdoor, and underground. Compatible scenarios refer to the primary application scenarios of the radon detector. If the compatible scenario cannot be directly determined based on the device's parameters, the degree of compatibility between the radon detector and different compatible scenarios can be calculated based on the detector's parameters, such as its detection range, accuracy, and minimum alarm concentration. The compatible scenario with the highest degree of compatibility is then determined as the detector's compatible scenario.
[0073] To obtain the temperature and humidity parameters corresponding to the adaptation scenario, the following steps need to be performed.
[0074] First, the temperature parameters and humidity parameters of the adaptation scene are obtained. The temperature parameters and humidity parameters here are directly determined based on the optional temperature and optional humidity corresponding to the adaptation scene or are instantly obtained from the corresponding type of real adaptation scene through sensors.
[0075] Secondly, the first preset weight and the second preset weight corresponding to the adaptation scene are obtained. Since the effects of temperature and humidity on radon gas are different in different scenes, the temperature parameter is corrected by the first preset weight, and the humidity parameter is corrected by the second preset weight.
[0076] In an outdoor environment, the temperature and humidity have little effect on the radon detector, and the first preset weight is equal to the second preset weight.
[0077] In indoor environments, temperature affects air pressure inside and outside a building, leading to the chimney effect. High humidity may slightly increase the radon exhalation rate of building materials (increasing pore permeability), but the effect is not significant. Therefore, the impact of temperature outweighs the impact of humidity, and the first preset weight is greater than the second preset weight.
[0078] In an underground environment, temperature mainly affects the diffusion of gas based on the principle of thermal diffusion. In a geological environment, if the humidity is too high, water and steam will fill the gaps in gravel or sand, thereby significantly affecting the diffusion of gas. Therefore, in an underground environment, the influence of temperature is lower than the influence of humidity, and the first preset weight is less than the second preset weight.
[0079] Based on the above description, the second test concentration satisfies the following formula (1).
[0080] (1)
[0081] in, P 1 is the lowest alarm concentration, P 2 is the second test concentration, K 1 is the temperature parameter, T 1 is the first preset weight, K 2 is the humidity parameter, T 2 is the second preset weight, T 1+ T 2=1.
[0082] Optionally, if the adaptation scenario is an outdoor environment, the second test concentration is calculated based on the minimum alarm concentration, the temperature parameter, the humidity parameter, the first preset weight, and the second preset weight, specifically including: obtaining the air temperature, relative humidity, and rainfall correction parameter (the rainfall correction parameter is positively correlated with the precipitation) according to the adaptation scenario, and the second test concentration satisfies the following formula (2).
[0083] (2)
[0084] in, P 1 is the lowest alarm concentration, P 2 is the second test concentration, K 1 is the temperature parameter, K 2 is the humidity parameter, T is the temperature, His the relative humidity, a Correction parameter for rainfall.
[0085] On the premise that the adaptation scenario is an outdoor environment, the calculation of the second test concentration mainly considers the influence of three environmental factors: room temperature, relative humidity and rainfall. The influence of temperature on the test concentration is calculated according to the air temperature and temperature parameters, the influence of humidity on the test concentration is calculated according to the relative humidity and humidity parameters, and the influence of rainfall on the test concentration is calculated according to the rainfall correction parameters, thereby improving the accuracy of the first test concentration in the outdoor environment.
[0086] If the adaptation scene is an indoor environment, the temperature parameters and humidity parameters corresponding to the adaptation scene are obtained according to the adaptation scene, specifically including: obtaining the indoor and outdoor temperature difference, relative humidity and building permeability coefficient (the permeability coefficient is positively correlated with the permeability of the indoor environment) according to the adaptation scene, and the second test concentration satisfies the following formula (3).
[0087] (3)
[0088] in P 1 is the lowest alarm concentration, P 2 is the second test concentration, K 1 is the temperature parameter, K 2 is the humidity parameter, is the temperature difference between indoor and outdoor, H is the relative humidity, b is the building permeability coefficient.
[0089] On the premise that the adaptation scenario is an indoor environment, the calculation of the second test concentration mainly considers the influence of the indoor and outdoor temperature difference, relative humidity, and the building permeability coefficient formed by the indoor building type or material on the test concentration. The influence of temperature on the test concentration is calculated based on the indoor and outdoor temperature difference and temperature parameters, and the influence of humidity on the test concentration is calculated based on the relative humidity and humidity parameters. At the same time, the concentration is corrected by considering the influence of the building permeability coefficient combined with temperature and humidity, thereby improving the accuracy of the second test concentration in the indoor environment.
[0090] If the adaptation scenario is an underground environment, the temperature parameters and humidity parameters corresponding to the adaptation scenario are obtained according to the adaptation scenario, specifically including: obtaining the underground environment temperature, underground environment humidity, pore structure coefficient (the looseness of the geology is negatively correlated with the pore structure coefficient, for example, 1.2 for sandstone geology and 0.7 for clay geology) and humidity saturation threshold according to the adaptation scenario, and the second test concentration satisfies the following formula (4).
[0091] (4)
[0092] Among them, P 1 is the lowest alarm concentration, P 2 is the second test concentration,K 1 is the temperature parameter, K 2 is the humidity parameter, t is the underground ambient temperature, h is the underground environmental humidity, c is the pore structure coefficient, d is the humidity saturation threshold.
[0093] On the premise that the adaptation scenario is an underground environment, the calculation of the second test concentration mainly considers the influence of humidity on the radon release capacity in different geological types and the influence of temperature on the diffusion of radon in the underground environment to calculate the second test concentration, thereby improving the accuracy of the second test concentration in the underground environment.
[0094] It should be noted that the additional data such as room temperature and relative humidity are directly determined based on the selectable value range corresponding to the adaptation scenario, and are instantly obtained from the corresponding type of real adaptation scenario through sensors.
[0095] As can be seen, in this embodiment of the application, by integrating scenario-based environmental parameters, the test distance used for testing is adjusted based on the impact of different usage scenarios of the radon detector on radon concentration. This optimizes the test parameters and takes into account the impact of environmental factors in different adaptation scenarios on radon concentration. This provides a more realistic test environment for the radon detector under test and improves the credibility of the test results.
[0096] S203: The test equipment controls the distance between the americium 241 radioactive source and the radon detector to meet the test distance, and controls the americium 241 radioactive source to be turned on.
[0097] Specifically, see Figure 3 , Figure 3 This is a schematic diagram of the partial structure of a test device provided in an embodiment of the present application, which includes an americium 241 radiation source 1011, a signal transceiver module 1012 (not shown in the figure), a micrometer 1013, a sliding connecting rod 1014, a detector placement table 1015, a coaxial cable connector 1016, and a detection darkroom 1017.
[0098] Micrometer 1013 has an adjustment range of 0-50 mm and an accuracy of 0.003-0.01 mm. Micrometer 1013, in conjunction with sliding link 1014, can adjust the distance between the americium-241 radioactive source 1011 and the radon detector under test, which is placed on the detector support 1015. The testing equipment uses micrometer 1013 and sliding link 1014 to adjust the distance from the radon detector to the test distance, simulating instantaneous changes in radon concentration.
[0099] The coaxial cable connector 1016 is used to connect the signal transceiver module 1012 and the radon gas detector to be tested placed on the detector placement platform 1015 through the coaxial cable. Figure 4 , Figure 4 A schematic diagram of the connection between a signal transceiver module and a radon detector under test provided in an embodiment of the present application. It can be seen that by connecting the radon detector under test 102 in a darkroom 1017 and the signal transceiver module 1012 outside the darkroom 1017, the signal transceiver module 1012 can collect data or send signals from the radon detector under test 102.
[0100] The detection darkroom 1017 is specifically an aluminum shielding darkroom that can avoid interference from the external environment and effectively isolate various rays released by americium 241 to protect the safety of operators.
[0101] S204: The test equipment obtains a plurality of first test data collected by the signal transceiver module from the radon detector under test while the americium 241 radioactive source is turned on. The first test data is electrical signal data corresponding to alpha particles generated by the americium 241 radioactive source.
[0102] The first test data here is the electrical signal data, such as voltage, current, etc., generated by the alpha particles emitted by the americium 241 radioactive source collected by the radon detector under test.
[0103] S205: The testing device determines a test result of the tested radon gas detector according to the plurality of first test data.
[0104] The testing equipment determines the test result of the radon detector under test based on whether the values or characteristics of multiple first test data conform to the characteristics of americium 241 (for example, whether the values conform to the range corresponding to americium 241, whether the data distribution conforms to the normal distribution, etc.).
[0105] Optionally, the test result of the radon gas detector under test is determined based on multiple first test data, including: judging whether the values of the multiple first test data are in a preset value range corresponding to americium 241; if the values of the multiple first test data are all in the preset value range, determining that the test result of the radon gas detector under test is a passed test; if the values of the multiple first test data are not all in the preset value range, determining that the test result of the radon gas detector under test is a failed test.
[0106] Specifically, since the main energy peak of α decay is near 5.486 MeV, the decay follows a normal distribution. Based on this characteristic, it is only necessary to determine whether the values of multiple first test data are within the preset numerical range corresponding to americium-241 to determine whether the electrical signal data generated by the radon detector under test based on α particles emitted by americium-241 meets the characteristics of americium-241. If it meets the characteristics of americium-241, it can be determined that the radon detector under test is qualified in its α particle detection function, and thus it can be confirmed that the radon detector under test can also normally generate the corresponding electrical signal when detecting α particles produced by radon decay. Therefore, if the values of multiple first test data are all within the preset numerical range, the test result of the radon detector under test is determined to be passed.
[0107] For example, the multiple first test data here include voltage signal data generated by the radon detector under test based on alpha particles emitted by americium 241. The preset numerical range here is 230±50mv. If the data all fall within the range, then it can be determined that the radon detector under test has passed the test.
[0108] Optionally, before determining whether the values of the plurality of first test data are within a preset value range, the method further includes: determining the first test data among the plurality of first test data that is lower than a first preset value as invalid data.
[0109] Specifically, it's important to note that americium-241 decays primarily through alpha decay (accounting for approximately 85%): 241Am → 237Np + alpha (5.486 MeV), with the alpha particle having an energy of 5.486 MeV. This decay is followed by gamma decay (accounting for approximately 35.9%), which releases low-energy gamma rays (59.5 keV). Other minor radiation sources include Np's L-series X-rays (energy approximately 13-22 keV) and weak gamma rays (26.3 keV and 33.2 keV, respectively) (intensity <1%).
[0110] As shown in the decay of americium-241, multiple energies can occur. If a single high-energy alpha particle (5.48 MeV) produced by an americium-241 radioactive source is used, other energies must be filtered out. The alpha decay energy (5.486 MeV) is nearly 100 times greater than the gamma decay energy (59.5 keV), and the resulting voltage is also nearly 100 times greater. Therefore, among the multiple first test data, the first test data that falls below a first preset value must be deemed invalid. This first test data corresponds to the energy of the alpha particle produced by the decay of americium-241.
[0111] For example, the voltage corresponding to the α decay energy in the present solution is 230 mV, so the voltage of the γ decay energy is about 2 mV. In order to leave only the α decay energy, the threshold of the present solution sets the first preset value to 180 mV.
[0112] It can be seen that in the embodiment of the present application, by judging whether multiple first test data are in a preset numerical range, it can be determined whether the test function of the radon gas detector under test for alpha particles produced by the decay of americium 241 is qualified. On the premise that the test function of the radon gas detector under test for alpha particles produced by the decay of americium 241 is qualified, the test result of the radon gas detector under test can be determined as a passed test, thereby realizing the automated testing of radon gas detectors based on americium 241 and improving the test efficiency.
[0113] Example 2: The above application embodiment provides a test method for determining the detection result of a radon gas detector based on multiple first test data. Based on this, this application also provides a more detailed test method for radon gas detectors of different types. Figure 5 , Figure 5 A flowchart of another method for testing a radon detector provided in an embodiment of the present application includes steps S501-S505.
[0114] S501: The test equipment controls the americium 241 radioactive source to adjust the distance between the americium 241 radioactive source and the radon detector under test from a maximum distance to a minimum distance.
[0115] Specifically, in an embodiment of the present application, before testing the radon detector under test according to the first test concentration, the testing equipment will directly control the americium 241 radioactive source at a preset speed to gradually move the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the radon detector under test until the distance between the two is adjusted to the minimum distance.
[0116] S502: The test equipment obtains alarm information collected by the signal transceiver module from the radon detector under test during the process of adjusting the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance.
[0117] During the process of adjusting the distance between the americium 241 radioactive source and the radon detector being tested from the maximum distance to the minimum distance, the test equipment will continuously determine whether the alarm information of the detector has been collected. The alarm information is generated by the radon detector being tested on the premise that radon gas is detected. It should be noted that the radon gas here refers to the simulated radon gas environment simulated by the test equipment through the americium 241 radioactive source, and does not mean that radon gas actually exists.
[0118] S503: If the test equipment obtains the alarm information collected by the signal transceiver module from the radon detector under test during the process of adjusting the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance, then the triggering distance between the americium 241 radioactive source and the radon detector under test when the radon detector under test generates the alarm information is determined according to the collection time of the alarm information.
[0119] Specifically, in the embodiment of the present application, if the device type of the radon detector being tested is a threshold alarm type device (an alarm is triggered if alpha particles with energy that meets a preset energy threshold are detected, and the preset energy threshold is the energy of alpha particles generated by radon decay), then the radon detector being tested will have its alarm mechanism triggered during the process of adjusting the distance between the americium 241 radioactive source and the radon detector being tested from the maximum distance to the minimum distance, thereby generating the alarm information here.
[0120] The test equipment will collect alarm information from the radon detector under test through the signal transceiver module, and record the distance between the americium 241 radioactive source and the radon detector under test when the alarm information is generated, that is, the trigger distance here.
[0121] S504: The testing device determines the alarm triggering concentration of the radon detector being tested according to the triggering distance.
[0122] The test device can specifically determine the simulated radon gas concentration corresponding to the trigger distance, ie, the alarm triggering concentration here, through the correspondence between the preset test concentration and the test distance.
[0123] S505: If the alarm triggering concentration is not greater than the first test concentration, the testing device determines that the test result of the tested radon gas detector is a passed test.
[0124] Specifically, it should be noted that the alpha particle energy of the test device in the embodiment of this application is 5.48 MeV, while the energy range of radon decay alpha particles produced by real radon gas is 6.0-7.7 MeV. Considering the triggering mechanism of a threshold alarm-type radon detector, a radon detector with a reasonable electrical signal value fluctuation threshold alarm does not necessarily set the preset energy threshold to 6.0-7.7 MeV. It may also set it to a value such as 5.5-8.0 MeV to ensure fault tolerance. Therefore, in some cases, the alarm-type radon detector may be triggered by the americium-241 radioactive source in this embodiment.
[0125] Based on the above reasons, under the premise that the alarm triggering concentration is not greater than the first test concentration, it is proved that the radon gas being tested can detect radon gas of no greater than the first test concentration, and therefore the test result of the radon gas detector being tested is determined to be a passed test.
[0126] Furthermore, if the testing device does not obtain the alarm information collected by the signal transceiver module from the radon detector under test during the process of adjusting the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance, or the alarm triggering concentration is greater than the first test concentration, the test steps S201-S205 are executed to test the radon detector under test when the test results of the radon detector under test cannot be determined through the test steps S501-S505.
[0127] It can be seen that in the embodiment of the present application, the radon detector under test of the threshold alarm type is tested by using the alarm information and related data obtained in the process of adjusting the distance between the americium 241 radioactive source and the radon detector under test from the maximum distance to the minimum distance. When the alarm information obtained by the test equipment is successful, the test result of the radon detector under test can be determined based on the alarm information and related signals, and there is no need to execute subsequent steps, thereby improving the test efficiency.
[0128] Example 3: The above application embodiment provides a test method for a radon gas detector of the threshold alarm type. Based on this, the present application embodiment also provides another test method for different types of radon gas detectors. Figure 6 , Figure 6 A flowchart of another method for testing a radon gas detector provided in an embodiment of the present application includes steps S601-S604.
[0129] S601: The testing device determines the alarm type of the radon detector being tested. The alarm type includes a threshold alarm type or a data feature alarm type.
[0130] Specifically, in the embodiments of the present application, it is necessary to determine the alarm type of the radon detector being tested. Alarm types include threshold alarm type and data feature alarm type. The specific operating method of the threshold alarm type detector is described above and will not be repeated here. The data feature alarm type detector, on the other hand, detects and issues an alarm based on the signal characteristics of the electrical signal corresponding to alpha particles in the environment to determine the radon concentration in the tested environment.
[0131] S602: If the alarm type of the radon detector under test is a data characteristic alarm type, the testing device generates alarm information of the radon detector under test according to the first test concentration, and the alarm information is used to simulate a radon environment of the first test concentration.
[0132] Specifically, based on the alarm mechanism of the radon gas detector under test of the data characteristic alarm type, for the radon gas detector under test of the data characteristic alarm type, under the premise that the americium 241 radioactive source is used to replace the radon source in the present invention, the detection device in the present invention is difficult to trigger the alarm mechanism of the radon gas detector under test of the characteristic alarm type.
[0133] The alarm information here is an electrical signal simulating the first test concentration of radon gas. If the function of the radon gas detector being tested is normal, then when the radon gas detector being tested detects the first test concentration of radon gas, it will generate a signal identical to the alarm information, thereby triggering the alarm mechanism to generate alarm information.
[0134] In addition, if the alarm type of the radon detector being tested is a threshold alarm type, the test steps S501-S505 are executed. Detailed descriptions are given in the relevant descriptions of steps S501-S505, which will not be repeated here.
[0135] S603: The test equipment controls the signal transceiver module to send an alarm message to the radon detector under test.
[0136] Specifically, the test equipment sends alarm information to the detector under test through the signal transceiver module, so as to send the alarm information to the microprocessor MCU of the radon detector under test, so that the MCU of the radon detector under test receives the same signal as when it detects the first test concentration of radon, thereby testing whether the alarm mechanism of the radon detector under test can be triggered normally.
[0137] S604: If no alarm information is received, the testing device determines the test result of the radon detector being tested as a test failure.
[0138] Specifically, if no alarm information is received, it can be determined that the MCU of the radon detector under test cannot normally trigger the alarm mechanism for alarming when the radon concentration exceeds the standard, and therefore the test result of the radon detector under test is test failure.
[0139] If an alarm message is received, the test steps S201-S205 are executed to test whether the radon detector under test has a normal detection function for alpha particles. Detailed descriptions can be found in the relevant descriptions of steps S201-S205, which will not be repeated here.
[0140] See Figure 7 , Figure 7 A detection logic diagram for different types of radon gas detectors provided in an embodiment of the present application.
[0141] First, in this solution, for devices of the threshold alarm type, the radon detector test device first performs a test of the americium 241 radioactive source without a specific distance (ie, the contents described in steps S501-S505).
[0142] If the test result of the radon detector cannot be determined in the test without the specific distance of the Americium 241 radioactive source, the test is performed using the Americium 241 radioactive source in combination with the first test concentration (ie, the contents described in steps S201-S205).
[0143] Next, for devices with signal characteristic alarms, the radon detector tester first performs an alarm message test (i.e., the test described in steps S601-S604). If no alarm message is received, the radon detector is determined to have failed the test.
[0144] If an alarm message is received during the alarm message test, the test is performed using an americium 241 radioactive source in combination with a first test concentration, and the test is performed using an americium 241 radioactive source in combination with a first test concentration.
[0145] Finally, for other types or unknown types of radon detectors being tested, they are directly tested using the americium 241 radioactive source combined with the first test concentration, thereby achieving the test of all types of radon detectors and improving the test efficiency of threshold alarm type radon detectors and signal characteristic alarm type radon detectors.
[0146] It can be seen that in the embodiment of the present application, an alarm message is sent to the radon detector under test through the signal transceiver module, and the radon detector under test is tested. If the alarm message generated by the radon detector under test cannot be obtained, the test result of the radon detector under test is determined to be a test failure, and there is no need to execute subsequent steps of testing according to the test distance, thereby improving the test efficiency.
[0147] Through the method in the above-mentioned application embodiment, it can be seen that the present invention determines the test results of the radon detector under test by obtaining multiple first test data, thereby realizing the replacement of the traditional radon source with the americium 241 radioactive source in the test of the radon detector, and solving the various problems caused by the traditional radon source. Different test processes are executed for different types of radon detectors under test, and dark current tests are performed on the radon detectors under test, thereby improving the test efficiency. The reliability of the test results is improved by optimizing the test parameters through the integration of scenario-based environmental parameters and dynamic weighting mechanism. The data of multiple first test data is filtered by the first preset value, thereby improving the processing efficiency of the test equipment.
[0148] Based on the description of the above configuration method embodiment, the present application also provides a radon gas detector test device, which includes an americium 241 radiation source (not shown in the figure) and a signal transceiver module (not shown in the figure). The americium 241 radiation source is used to generate alpha particles, and the signal transceiver module is used to collect signal data generated during the operation of the radon gas detector, or to send signals to the radon gas detector.
