Description

Technical Field

[0001] The present invention relates to the field of optical detection, and particularly to a test method for a radon gas detector and related equipment. Background Art

[0002] Radon is a radioactive noble gas, which is usually released from radium and uranium in soil and rocks during the natural decay process in nature. In order to detect the radon gas concentration in the environment to be measured, the radon gas detector specifically generates corresponding electrical signals by detecting the α particles of radon gas, and then judges the radon gas concentration in the environment to be measured according to the characteristics such as the peak value and waveform data of the electrical signals.

[0003] In the prior art, the radon gas detector is usually detected by a radon chamber. A radon chamber is a device that simulates the real environment to test the performance of a radon sensor by controlling parameters such as radon gas concentration, temperature, and humidity. Among them, radium or uranium or their isotopes are used as the radon source for generating radon gas, which leads to problems such as high danger of radioactive substances, high construction and maintenance costs of the radon chamber, and high time cost for adjusting the radon concentration, resulting in too high detection costs for the radon gas detector. Summary of the Invention

[0004] In view of the above problems, the embodiments of the present application provide a test method for a radon gas detector and related equipment. The solution of the present application is beneficial to solving the problem of too high detection costs of the radon gas detector.

[0005] In a first aspect, the embodiments of the present application provide a test method for a radon gas detector, which is applied to a test device for a radon gas detector. The test device for a radon gas detector includes an americium-241 radiation source and a signal transceiver module. The americium-241 radiation source is used to generate α particles, and the signal transceiver module is used to collect signal data generated when the radon gas detector operates or send signals to the radon gas detector. The method includes: obtaining the device parameters of the radon gas detector to be tested, and determining the first test concentration of the radon gas detector to be tested according to the device parameters; determining the test distance of the radon gas detector to be tested according to the first test concentration, and the first test concentration is negatively correlated with the test distance; controlling the distance between the americium-241 radiation source and the radon gas detector to be tested to meet the test distance, and controlling the americium-241 radiation source to be turned on; obtaining a plurality of first test data collected from the radon gas detector to be tested by the signal transceiver module during the period when the americium-241 radiation source is turned on, and the first test data is the electrical signal data corresponding to the α particles generated by the americium-241 radiation source; determining the test result of the radon gas detector to be tested according to the plurality of first test data.

[0006] It can be seen that in the embodiments of the present application, by obtaining multiple first test data to determine the test result of the radon gas detector to be tested, the replacement of the americium-241 radiation source for the traditional radon source in the test of the radon gas detector is realized, thus solving the problems of high danger, high cost of radon chamber construction and maintenance, and too long radon concentration adjustment time caused by the traditional radon source in the test process of the radon gas detector, that is, the problem of too high detection cost of the radon gas detector.

[0007] Combined with the first aspect, in a possible embodiment, before determining the test distance of the radon gas detector to be tested according to the first test concentration, the method further includes: controlling the americium-241 radiation source to adjust the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance; obtaining the alarm information collected from the radon gas detector to be tested by the signal transceiver module during the process of adjusting the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance; if the alarm information collected from the radon gas detector to be tested by the signal transceiver module is obtained during the process of adjusting the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance, then determine the trigger distance between the americium-241 radiation source and the radon gas detector to be tested when the radon gas detector to be tested generates the alarm information according to the collection time of the alarm information; determine the alarm trigger concentration of the radon gas detector to be tested 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 gas detector to be tested is a pass.

[0008] It can be seen that in the embodiments of the present application, by testing the radon gas detector of the threshold alarm type with the alarm information and related data obtained during the process of adjusting the distance between the americium-241 radiation source and the radon gas detector to be tested 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 gas detector to be tested can be determined according to the alarm information and related signals, and subsequent steps do not need to be executed, improving the test efficiency.

[0009] Combined with the first aspect, in a possible embodiment, before controlling the americium-241 radiation source to adjust the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance, the method further includes: determining the alarm type of the radon gas detector to be tested, where the alarm type includes a threshold alarm type or a data feature alarm type; if the alarm type of the radon gas detector to be tested is a data feature alarm type, the method further includes: generating alarm information for the radon gas detector to be tested according to the first test concentration, where the alarm information is used to simulate the radon gas environment of the first test concentration; controlling the signal transceiver module to send the alarm information to the radon gas detector to be tested; if the alarm information is not received, then determine that the test result of the radon gas detector to be tested is a fail.

[0010] It can be seen that in the embodiment of the present application, an alarm message is sent to the radon gas detector under test through the signal transceiver module to test the radon gas detector under test. When the alarm message generated by the radon gas detector under test cannot be obtained, it is determined that the test result of the radon gas detector under test fails, and there is no need to execute the subsequent step of testing according to the test distance, which improves the test efficiency.

[0011] Combined with the first aspect, in a possible embodiment, determining the test distance of the radon gas detector under test according to the first test concentration includes: determining the lowest alarm concentration of the radon gas detector under test according to the first test concentration; determining the adaptation scenario of the radon gas detector under test according to the device parameters, where the adaptation scenario includes an indoor scenario, an outdoor scenario, or an underground scenario; obtaining the temperature parameter and humidity parameter corresponding to the adaptation scenario according to the adaptation scenario; where the temperature parameter represents the influence degree of the temperature in the adaptation scenario on the radon gas concentration, and the humidity parameter represents the influence degree of the humidity in the adaptation scenario on the radon gas concentration; calculating a second test concentration according to the lowest alarm concentration, the temperature parameter, and the humidity parameter; and determining the test distance according to the second test concentration and the preset corresponding relationship between the test concentration and the distance.

[0012] It can be seen that in the embodiment of the present application, by fusing the scenario-based environmental parameters, the test distance for testing is adjusted according to the influence of different usage scenarios of the radon gas detector under test on the radon gas concentration. The test parameters are optimized, considering the influence of environmental factors in different adaptation scenarios on the radon gas concentration, providing a more realistic test environment for the test of the radon gas detector under test, and improving the credibility of the test result.

[0013] Combined with the first aspect, in a possible embodiment, determining the test result of the radon gas detector under test according to multiple first test data includes: determining whether the values of the multiple first test data are within the preset value range corresponding to americium-241; if the values of the multiple first test data are all within the preset value range, it is determined that the test result of the radon gas detector under test is passed; if the values of the multiple first test data are not all within the preset value range, it is determined that the test result of the radon gas detector under test is failed.

[0014] It can be seen that in the embodiment of the present application, by determining whether multiple first test data are within the preset value range, it can be determined whether the test function of the radon gas detector under test for the α particles generated by the decay of americium-241 is qualified. On the premise that the test function of the radon gas detector under test for the α particles generated by the decay of americium-241 is qualified, it can be determined that the test result of the radon gas detector under test is passed, thus realizing the automated test of the radon gas detector 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 a plurality of first test data are within a preset value range, the method further includes: determining, as invalid data, the first test data among the plurality of first test data that is lower than a first preset value.

[0016] It can be seen that in the embodiment of the present application, by using the first preset value to filter the plurality of first test data, the data that does not conform to the α-particle energy is determined as invalid data, reducing the data processing amount of the test device, thereby improving the processing efficiency of the test device.

[0017] In combination with the first aspect, in a possible embodiment, the method further includes: acquiring a plurality of second test data collected by the signal transceiver module from the radon gas detector to be tested within a preset time, where the second test data is dark current signal data generated by the radon gas detector to be tested; 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 to be tested fails.

[0018] It can be seen that in the embodiment of the present application, by using the test device of the radon gas detector to acquire a plurality of second test data of the radon gas detector to be tested, the dark current situation of the radon gas detector to be tested can be judged first. If the dark current of the radon gas detector to be tested fluctuates greatly, it is directly determined that the test result of the radon gas detector to be tested fails, without performing subsequent steps, improving the test efficiency.

[0019] In a second aspect, the embodiment of the present application further provides a test device for a radon gas detector. The test device for a radon gas detector includes an americium-241 radiation source and a signal transceiver module.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0029] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0030] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0031] Embodiment 1: Please refer to Figure 1 ,Figure 1 FIG. 1 is a schematic diagram of an application scenario of a test method for a radon gas detector provided by an embodiment of the present application. The application scenario 100 includes a test device 101, a radon gas detector 102 to be tested, and a terminal device 103.

[0032] The test device 101 is a test device for a radon gas detector, including an americium-241 radiation source 1011 and a signal transceiver module 1012. The americium-241 radiation source 1011 contains americium-241. The half-life of americium-241 is about 432.2 years. It is a relatively safe and easily obtainable alpha radiation source. The main energy of alpha is 5.48 MeV, with weak penetration, and it also emits a small amount of gamma rays. Here, the americium-241 radiation source 1011 is used to simulate radon gas to implement the detection of the radon gas detector.

[0033] The signal transceiver module 1012 is used to connect to the radon gas detector 102 to be tested and obtain signal data from the radon gas detector 102 to be tested or send signals to the radon gas detector 102 to be tested.

[0034] The terminal device 103 is used to connect to the test device 101 and send device parameters to the test device 101 or obtain detection results, etc.

[0035] In the embodiment of the present application, after the radon gas detector 102 to be tested is placed on the test device 101, the test device 101 obtains the device parameters of the radon gas detector 102 to be tested and determines the first test concentration of the radon gas detector 102 to be tested according to the device parameters.

[0036] The first test concentration is determined by the test device 101 based on the device parameters of the radon gas detector 102 to be tested, and it is the radon gas concentration that can trigger an alarm of the radon gas detector 102 to be tested.

[0037] The test device 101 determines the test distance of the radon gas detector 102 to be tested according to the first test concentration. The first test concentration is negatively correlated with the test distance. That is to say, the higher the first test concentration, the closer the test distance, and the lower the first test concentration, the farther the test distance.

[0038] The test device 101 controls the distance between the americium-241 radiation source 1011 and the radon gas detector 102 to be tested to meet the test distance and controls the americium-241 radiation source 1011 to be turned on.

[0039] The test device 101 obtains a plurality of first test data collected from the radon gas detector 102 to be tested by the signal transceiver module during the period when the americium-241 radiation source 1011 is turned on. The first test data is the electrical signal data corresponding to the alpha particles generated by the americium-241 radiation source 1011.

[0040] The multiple first test data here include the electric signals generated by the α particles produced by the decay of americium-241 received by the radon gas detector 102 under test during the activation of the americium-241 radiation source 1011.

[0041] The test device 101 determines the test result of the radon gas detector 102 under test according to the multiple first test data.

[0042] The test device 101 determines the test result of the radon gas detector 102 under test according to the data characteristics or values of the multiple first test data, and specifically judges based on whether the multiple first test data conform to the data characteristics corresponding to the α particles generated by americium-241.

[0043] It can be seen that in the embodiment of the present application, by obtaining multiple first test data to determine the test result of the radon gas detector under test, the replacement of the traditional radon source with the americium-241 radiation source in the test of the radon gas detector is realized, thereby solving the problems of high danger, high cost of radon chamber construction and maintenance, and too long radon concentration adjustment time caused by the traditional radon source in the test process of the radon gas detector, that is, the too high detection cost of the radon gas detector.

[0044] The following will be described in conjunction with specific steps. Please refer to Figure 2 , Figure 2 is a schematic flowchart of a method for testing a radon gas detector provided by an embodiment of the present application, including steps S201-S205.

[0045] S201: The test device obtains the device parameters of the radon gas detector under test, and determines the first test concentration of the radon gas detector under test according to the device parameters.

[0046] Specifically, the device parameters here include parameters such as the detection concentration range (for example, 200 Bq / m³ - 400 Bq / m³) or alarm concentration (such as 200 Bq / m³) of the radon gas detector under test. Specifically, it can be obtained through information such as the device type and model of the radon gas detector under test.

[0047] Optionally, the method further includes: obtaining multiple second test data collected from the radon gas detector under test by the signal transceiver module within a preset time, where the second test data is the dark current signal data generated by the radon gas detector under test; if the sum of the multiple 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 unqualified.

[0048] Specifically, since the α particles generate a pA-level current in the radon gas detector under test, if the sensor dark current fluctuates greatly, it will affect the accuracy of the data. Therefore, before testing the radon gas detection performance of the radon gas detector under test, it is also necessary to detect the dark current of the radon gas detector under test.

[0049] Before obtaining the device parameters of the radon gas detector to be tested, the test device can also collect multiple second test data obtained by the radon gas detector to be tested through the signal transceiver module within a preset time. Here, the multiple second test data specifically includes multiple current data collected under the same voltage (such as 20mv). The multiple second test data is used to characterize the dark current fluctuation of the radon gas detector to be tested.

[0050] The test device specifically judges the dark current situation of the radon gas detector to be tested according to the data characteristics of the multiple second test data, such as the mean value, standard deviation, etc. of the multiple second test data. In the embodiment of the present application, if the sum of the multiple second test data is greater than the second preset value, it is determined that the dark current fluctuation of the radon gas detector to be tested is large, and the test result of the radon gas detector to be tested is a failed test.

[0051] It can be seen that in the embodiment of the present application, by obtaining multiple second test data of the radon gas detector to be tested through the test device of the radon gas detector, the dark current situation of the radon gas detector to be tested can be judged first. If the dark current fluctuation of the radon gas detector to be tested is large, it is directly determined that the test result of the radon gas detector to be tested is a failed test, without the need to perform subsequent steps, which improves the test efficiency.

[0052] S202: The test device determines the test distance of the radon gas detector to be tested according to the first test concentration, and the first test concentration is negatively correlated with the test distance.

[0053] Here, the test distance is determined according to the corresponding relationship between the preset test concentration and the test distance. For any value in the detection concentration range of the radon gas detector to be tested, the test device will then adjust the distance between the americium-241 radiation source and the radon gas detector to be tested to the test distance to simulate the radon gas environment of the test concentration.

[0054] Optionally, determining the test distance of the radon gas detector to be tested according to the first test concentration includes: determining the lowest alarm concentration of the radon gas detector to be tested according to the first test concentration; determining the adapted scenario of the radon gas detector to be tested according to the device parameters, and the adapted scenario includes indoor scenario, outdoor scenario or underground scenario; obtaining the temperature parameter and humidity parameter corresponding to the adapted scenario according to the adapted scenario; wherein, the temperature parameter characterizes the influence degree of the temperature in the adapted scenario on the radon gas concentration, and the humidity parameter characterizes the influence degree of the humidity in the adapted scenario on the radon gas concentration; calculating the second test concentration according to the lowest alarm concentration, temperature parameter and humidity parameter; and determining the test distance according to the second test concentration and the preset corresponding relationship between the test concentration and the distance.

[0055] Specifically, it should be noted that temperature and humidity can affect the true concentration of radon gas, and may also affect the detection results of radon gas detectors under the same environment and the same concentration. Different temperatures and humidities may cause radon gas detectors to detect different values under the same environment and the same concentration.

[0056] If the radon gas in the environment reaches the target concentration, but due to the influence of the temperature and humidity of the environment, the radon gas detector cannot detect the correct concentration value, resulting in the radon gas detector being unable to give an alarm in time. Therefore, in the embodiment of the present application, the test concentration is corrected through a dynamic environment compensation mechanism, so as to simulate a more realistic test environment through the americium-241 radiation source.

[0057] The test device first determines the lowest alarm concentration of the radon gas detector to be tested according to the first test concentration. When the radon gas detector to be tested detects that the radon gas concentration in the environment is the lowest alarm concentration, the radon gas detector to be tested will give an alarm.

[0058] Determine the applicable scenario of the radon gas detector to be tested according to the device parameters. The applicable scenarios include indoor scenarios, outdoor scenarios or underground scenarios. The applicable scenario refers to the main application scenario of the radon gas detector to be tested. On the premise that the applicable scenario cannot be directly determined according to the device parameters, the matching degree of the radon gas detector to be tested with different applicable scenarios can also be calculated according to device parameters such as the detection range, detection accuracy and lowest alarm concentration of the radon gas detector to be tested, and then the applicable scenario with the highest matching degree is determined as the applicable scenario of the radon gas detector to be tested.

[0059] To obtain the temperature parameter and humidity parameter corresponding to the applicable scenario, the following steps need to be specifically executed.

[0060] First, obtain the temperature parameter and humidity parameter of the applicable scenario. Here, the temperature parameter and humidity parameter are directly determined based on the optional temperature and optional humidity corresponding to the applicable scenario or obtained immediately from the real applicable scenario of the corresponding type through a sensor.

[0061] Secondly, obtain the first preset weight and the second preset weight corresponding to the applicable scenario. Since the influence of temperature and humidity on radon gas is different in different scenarios, the temperature parameter is corrected by the first preset weight here, and the humidity parameter is corrected by the second preset weight.

[0062] In the outdoor environment, the influence of temperature and humidity on the radon gas detector is small, and the first preset weight is equal to the second preset weight.

[0063] In the indoor environment, temperature will affect the air pressure inside and outside the building, resulting in the chimney effect. For humidity, high humidity may slightly increase the radon release rate of building materials (the pore permeability increases), but the effect is not significant. Therefore, the influence of temperature is higher than that of humidity, and the first preset weight is greater than the second preset weight.

[0064] In the underground environment, temperature mainly affects the diffusion of gas based on the principle of thermal diffusion. In the geological environment, if the humidity is too high, water and steam will fill the gaps in sand and gravel or sandy soil, thus significantly affecting the diffusion of gas. Therefore, in the underground environment, the influence of temperature is lower than that of humidity, and the first preset weight is less than the second preset weight.

[0065] Based on the above description, the second test concentration satisfies the following formula (1).

[0066] (1) Wherein, 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.

[0067] Optionally, if the adapted scenario is an outdoor environment, the second test concentration is calculated according to the lowest alarm concentration, temperature parameter, humidity parameter, first preset weight and second preset weight. Specifically, it includes: obtaining the air temperature, relative humidity and rainfall correction parameter (the rainfall correction parameter is positively correlated with the precipitation amount) according to the adapted scenario. The second test concentration satisfies the following formula (2).

[0068] (2) Wherein, 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 air temperature, H is the relative humidity, a is the rainfall correction parameter.

[0069] On the premise that the adapted 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 parameter, the influence of humidity on the test concentration is calculated according to the relative humidity and humidity parameter, and the influence of rainfall on the test concentration is calculated according to the rainfall correction parameter, thereby improving the accuracy of the first test concentration in the outdoor environment.

[0070] If the adaptation scenario is an indoor environment, obtain the temperature parameter and humidity parameter corresponding to the adaptation scenario according to the adaptation scenario, specifically including: obtain the indoor-outdoor temperature difference, relative humidity, and building permeability coefficient (the permeability coefficient is positively correlated with the permeability rate of the indoor environment) according to the adaptation scenario, and the second test concentration satisfies the following formula (3).

[0071] (3) Where 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 indoor-outdoor temperature difference, H is the relative humidity, b is the building permeability coefficient.

[0072] 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-outdoor temperature difference, relative humidity, and building permeability coefficient formed by the indoor building type or material on the test concentration. Calculate the influence of temperature on the test concentration according to the indoor-outdoor temperature difference and temperature parameter, calculate the influence of humidity on the test concentration according to the relative humidity and humidity parameter, and at the same time consider the influence of the building permeability coefficient combined with temperature and humidity to correct the concentration, thereby improving the accuracy of the second test concentration in the indoor environment.

[0073] If the adaptation scenario is an underground environment, obtain the temperature parameter and humidity parameter corresponding to the adaptation scenario according to the adaptation scenario, specifically including: obtain 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, take 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).

[0074] (4) Wherein, wherein 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 environment temperature, h is the underground environment humidity, c is the pore structure coefficient, d is the humidity saturation threshold.

[0075] On the premise that the adaptation scenario is the underground environment, the calculation of the second test concentration mainly considers the influence of humidity on the radon release ability in different geological types and the influence of temperature on the radon diffusion in the underground environment to calculate the second test concentration, thereby improving the accuracy of the second test concentration in the underground environment.

[0076] It should be noted that the above-mentioned additional data such as room temperature and relative humidity are specifically determined directly based on the selectable value range corresponding to the adaptation scenario and are obtained instantaneously from the real adaptation scenario of the corresponding type through sensors.

[0077] It can be seen that in the embodiments of the present application, by integrating scenario-based environmental parameters, the test distance for testing is adjusted according to the influence of different usage scenarios of the radon detector to be tested on the radon concentration. The test parameters are optimized, and the influence of environmental factors in different adaptation scenarios on the radon concentration is considered, providing a more realistic test environment for the test of the radon detector to be tested and improving the credibility of the test results.

[0078] S203: The test equipment controls the distance between the americium-241 radiation source and the radon detector to be tested to meet the test distance and controls the americium-241 radiation source to be turned on.

[0079] Specifically, please refer to Figure 3 , Figure 3 which is a partial structural schematic diagram of a test equipment provided by an embodiment of the present application, including 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 connector 1016, and a detection darkroom 1017.

[0080] The adjustment range of the micrometer 1013 is specifically 0 - 50 mm, and the accuracy is 0.003 - 0.01 mm. The micrometer 1013 cooperates with the sliding connecting rod 1014 to adjust the distance between the americium-241 radiation source 1011 and the radon detector to be tested placed on the detector placement table 1015. The test equipment specifically adjusts the distance of the radon detector to be tested to the test distance through the micrometer 1013 and the sliding connecting rod 1014 to simulate the instantaneous change of the radon concentration.

[0081] The coaxial connector 1016 is used to connect the signal transceiver module 1012 and the radon detector to be tested placed on the detector placement table 1015 through a coaxial cable. Please refer to Figure 4 , Figure 4Schematic diagram of the connection between a signal transceiver module provided by an embodiment of the present application and a radon gas detector to be measured. It can be seen that by connecting the radon gas detector 102 in the detection darkroom 1017 and the signal transceiver module 1012 outside the detection darkroom 1017, the signal transceiver module 1012 can collect data from the radon gas detector 102 to be measured or send signals.

[0082] The detection darkroom 1017 is specifically an aluminum shielding darkroom, which can avoid external environmental interference and effectively isolate various rays released by americium-241 to protect the safety of operators.

[0083] S204: The test equipment acquires a plurality of first test data collected by the signal transceiver module from the radon gas detector to be measured during the period when the americium-241 radiation source is turned on. The first test data is the electrical signal data corresponding to the alpha particles generated by the americium-241 radiation source.

[0084] The first test data here is the electrical signal data generated by the alpha particles emitted by the americium-241 radiation source collected by the radon gas detector to be measured, such as voltage, current, etc.

[0085] S205: The test equipment determines the test result of the radon gas detector to be measured according to the plurality of first test data.

[0086] The test equipment determines the test result of the radon gas detector to be measured according to whether the values or characteristics of the plurality of first test data conform to the characteristics of americium-241 (for example, whether the values conform to the corresponding range of americium-241, whether the data distribution conforms to the normal distribution, etc.).

[0087] Optionally, determining the test result of the radon gas detector to be measured according to the plurality of first test data includes: judging whether the values of the plurality of first test data are within the preset value interval corresponding to americium-241; if the values of the plurality of first test data are all within the preset value interval, it is determined that the test result of the radon gas detector to be measured is a pass; if the values of the plurality of first test data are not all within the preset value interval, it is determined that the test result of the radon gas detector to be measured is a failure.

[0088] Specifically, since the energy main peak of alpha decay is around 5.486 MeV and the decay satisfies the normal distribution, according to this characteristic, it is only necessary to judge whether the values of the plurality of first test data are within the preset value interval corresponding to americium-241 to judge whether the electrical signal data generated by the radon gas detector to be measured based on the alpha particles emitted by americium-241 conforms to the characteristics of americium-241. If it conforms to the characteristics of americium-241, it can be determined that the radon gas detector to be measured is qualified in the function of detecting alpha particles, and thus it can be determined that the radon gas detector to be measured can also normally generate corresponding electrical signals when detecting alpha particles generated by radon gas decay. Therefore, if the values of the plurality of first test data are all within the preset value interval, it is determined that the test result of the radon gas detector to be measured is a pass.

[0089] Exemplarily, here, the multiple first test data include voltage signal data generated by the radon gas detector under test based on the α particles emitted by americium-241. The preset numerical range here is 230 ± 50 mv. If all the data fall within the range, then it can be determined that the radon gas detector under test passes the test.

[0090] Optionally, before determining whether the values of the multiple first test data are within the preset numerical range, the method further includes: determining the first test data that is lower than the first preset value among the multiple first test data as invalid data.

[0091] Specifically, it should be noted that the decay mode of americium-241 is mainly α decay (accounting for about 85%): 241Am → 237Np + α(5.486 MeV), and the energy of the α particle is 5.486 MeV. Secondly, there is γ decay (accounting for about 35.9%) accompanied by the release of low-energy γ rays (59.5 keV). And other minor radiations such as L-series X-rays of Np (energy about 13 - 22 keV); weak γ rays: 26.3 keV, 33.2 keV, etc. (intensity < 1%).

[0092] From the above decay of americium-241, it can be seen that multiple energies will appear during decay. If a single high-energy α particle (5.48 MeV) generated by an americium-241 radiation source is used, other energies need to be filtered out. The multiple relationship between the α decay energy (5.486 MeV) and the γ decay energy (59.5 keV) is close to 100 times, and the converted voltage values also have a relationship close to 100 times. Therefore, the first test data that is lower than the first preset value among the multiple first test data needs to be determined as invalid data. Here, the first test data corresponds to the energy of the α particles generated by the decay of americium-241.

[0093] Exemplarily, the designed voltage corresponding to the α decay energy in this solution is 230 mv. Therefore, the voltage of the γ decay energy is about 2 mv. In order to only retain the α decay energy, the threshold value of this solution sets the first preset value to 180 mv.

[0094] It can be seen that in the embodiments of the present application, by determining whether the multiple first test data are within the preset numerical range, it can be determined whether the test function of the radon gas detector under test for the α particles generated by the decay of americium-241 is qualified. On the premise that the test function of the radon gas detector under test for the α particles generated by the decay of americium-241 is qualified, it can be determined that the test result of the radon gas detector under test is a pass, thus realizing the automated test of the radon gas detector based on americium-241 and improving the test efficiency.

[0095] Embodiment 2: The above application embodiment provides a test method for judging the detection result of the radon gas detector to be tested based on a plurality of first test data. Based on this, the present application also provides a more detailed test method for radon gas detectors for different types of radon gas detectors. Please refer to Figure 5 , Figure 5 is a schematic flow chart of another test method for a radon gas detector provided by an embodiment of the present application, including steps S501-S505.

[0096] S501: The test equipment controls the americium-241 radiation source to adjust the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance.

[0097] Specifically, in the embodiment of the present application, before testing the radon gas detector to be tested according to the first test concentration, the test equipment will directly control the americium-241 radiation source at a preset speed to gradually approach the radon gas detector to be tested from the maximum distance until the distance between the two is adjusted to the minimum distance.

[0098] S502: The test equipment acquires the alarm information collected from the radon gas detector to be tested by the signal transceiver module during the process of adjusting the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance.

[0099] During the process of adjusting the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance, the test equipment will continuously determine whether the alarm information of the detector is collected. The alarm information is generated by the radon gas detector to be tested on the premise of detecting radon gas. 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 radiation source, rather than the real existence of radon gas.

[0100] S503: If the test equipment acquires the alarm information collected from the radon gas detector to be tested by the signal transceiver module during the process of adjusting the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance, then determine the trigger distance between the americium-241 radiation source and the radon gas detector to be tested when the radon gas detector to be tested generates the alarm information according to the acquisition time of the alarm information.

[0101] Specifically, in the embodiment of the present application, if the device type of the radon gas detector to be tested is a threshold alarm type (if α particles with energy meeting the preset energy threshold are detected, the alarm is triggered, and the preset energy threshold is the energy of the α particles generated by the decay of radon gas), then the radon gas detector to be tested will trigger the alarm mechanism during the process of adjusting the distance between the americium-241 radiation source and the radon gas detector to be tested from the maximum distance to the minimum distance, thereby generating the alarm information here.

[0102] The test device will collect the alarm information from the radon gas detector under test through the signal transceiver module, and at the same time record the distance between the americium-241 radiation source and the radon gas detector under test when the alarm information is generated, that is, the trigger distance here.

[0103] S504: The test device determines the alarm trigger concentration of the radon gas detector under test according to the trigger distance.

[0104] Specifically, the test device can determine the simulated radon gas concentration corresponding to the trigger distance, that is, the alarm trigger concentration here, through the preset corresponding relationship between the test concentration and the test distance.

[0105] S505: If the alarm trigger concentration is not greater than the first test concentration, the test device determines that the test result of the radon gas detector under test is a pass.

[0106] Specifically, it should be noted that in the embodiment of the present application, the α-particle energy of the test device is 5.48 MeV, while the energy range of the α-particles generated by real radon gas is 6.0 - 7.7 MeV. Considering the trigger mechanism of the threshold alarm type radon gas detector, the reasonable electrical signal numerical fluctuation threshold alarm type radon gas detector does not necessarily set the preset energy threshold to 6.0 - 7.7 MeV, and may also be set to values such as 5.5 - 8.0 MeV to ensure fault tolerance. Therefore, in some cases, the alarm type radon gas detector can be triggered by the americium-241 radiation source in this embodiment.

[0107] Based on the above reasons, on the premise that the alarm trigger concentration is not greater than the first test concentration, it is proved that the radon gas under test can detect radon gas not greater than the first test concentration. Therefore, it is determined that the test result of the radon gas detector under test can pass.

[0108] Further, if the test device does not obtain the alarm information collected by the signal transceiver module from the radon gas detector under test during the process of adjusting the distance between the americium-241 radiation source and the radon gas detector under test from the maximum distance to the minimum distance, or the alarm trigger concentration is greater than the first test concentration, then execute the test steps of S201 - S205 to implement the test of the radon gas detector under test in the case where the test result of the radon gas detector under test cannot be determined through the test steps of S501 - S505.

[0109] It can be seen that in the embodiment of the present application, the threshold alarm type radon gas detector under test is tested through the alarm information and related data obtained during the process of adjusting the distance between the americium-241 radiation source and the radon gas detector under test from the maximum distance to the minimum distance. When the alarm information obtained by the test device is successful, the test result of the radon gas detector under test can be determined according to the alarm information and related signals, and there is no need to execute subsequent steps, improving the test efficiency.

[0110] Embodiment 3: The above application embodiment provides a test method for a radon gas detector to be measured of the threshold alarm type. Based on this, the embodiment of the present application also provides another detection method for radon gas detectors of different types. Please refer to Figure 6 , Figure 6 which is a schematic flowchart of yet another test method for a radon gas detector provided by the embodiment of the present application, including steps S601 - S604.

[0111] S601: The test device determines the alarm type of the radon gas detector to be measured, and the alarm type includes the threshold alarm type or the data feature alarm type.

[0112] Specifically, in the embodiment of the present application, it is necessary to determine the alarm type of the radon gas detector to be measured, and the alarm type includes the threshold alarm type or the data feature alarm type. The specific working mode of the detector of the threshold alarm type is as described above and will not be elaborated here. The detector of the data feature alarm type is a radon gas detector that detects and alarms by judging the radon gas concentration in the environment to be measured based on the signal characteristics of the electrical signal corresponding to the α particles in the environment.

[0113] S602: If the alarm type of the radon gas detector to be measured is the data feature alarm type, the test device generates alarm information for the radon gas detector to be measured according to the first test concentration, and the alarm information is used to simulate the radon gas environment of the first test concentration.

[0114] Specifically, based on the alarm mechanism of the radon gas detector to be measured of the data feature alarm type, for the radon gas detector to be measured of the data feature alarm type, on the premise that the americium - 241 radiation source is used to replace the radon source in the present invention, it is difficult for the detection device in the present invention to trigger the alarm mechanism of the radon gas detector to be measured of the feature alarm type.

[0115] The alarm information here is the electrical signal simulating the radon gas of the first test concentration. If the function of the radon gas detector to be measured is normal, then when the radon gas detector to be measured detects the radon gas of the first test concentration, it will generate a signal identical to the alarm information, thereby triggering the alarm mechanism to generate alarm information.

[0116] In addition, if the alarm type of the radon gas detector to be measured is the threshold alarm type, the test steps of steps S501 - S505 are executed. For the detailed description, please refer to the relevant description of steps S501 - S505 and will not be elaborated here.

[0117] S603: The test device controls the signal transceiver module to send the alarm information to the radon gas detector to be measured.

[0118] Specifically, the test device sends an alarm message to the detector under test through the signal transceiver module, so as to send the alarm message to the microcontroller MCU of the radon gas detector under test, so that the MCU of the radon gas detector under test receives the same signal as when detecting radon gas at the first test concentration, and then tests whether the alarm mechanism of the radon gas detector under test can be triggered normally.

[0119] S604: If the alarm message is not received, the test device determines that the test result of the radon gas detector under test fails.

[0120] Specifically, if the alarm message is not received, it can be obtained that the MCU of the radon gas detector under test cannot normally trigger the alarm mechanism for alarming when the radon gas concentration exceeds the standard. Therefore, the test result of the radon gas detector under test is a failed test.

[0121] If the alarm message is received, the test steps of steps S201 - S205 are executed to test whether the detection function of the radon gas detector under test for alpha particles is normal. For detailed descriptions, please refer to the relevant descriptions of steps S201 - S205 and will not be elaborated here.

[0122] Please refer to Figure 7 , Figure 7 which is a schematic diagram of the detection logic for different types of radon gas detectors provided by the embodiments of the present application.

[0123] First, in this solution, for devices of the threshold alarm type, the test device of the radon gas detector first conducts a test without a specific distance for the americium - 241 radiation source (i.e., the content described in steps S501 - S505).

[0124] If the test result of the radon gas detector under test cannot be determined in the test without a specific distance for the americium - 241 radiation source, then a test is conducted by combining the americium - 241 radiation source with the first test concentration (i.e., the content described in steps S201 - S205).

[0125] Secondly, for devices of the signal feature alarm type, the test device of the radon gas detector first conducts a test through the alarm message test (i.e., the test described in steps S601 - S604). If the alarm message is not received, it is determined that the test result of the radon gas detector under test fails.

[0126] If the alarm message is received in the alarm message test, then a test is conducted by combining the americium - 241 radiation source with the first test concentration, and a test is obtained by combining the americium - 241 radiation source with the first test concentration.

[0127] Finally, for other types or unknown types of radon detectors to be tested, they are directly tested by the americium-241 radiation source in combination with the first test concentration, thereby realizing the testing of all types of radon detectors and improving the testing efficiency of the radon detectors of the threshold alarm type and the radon detectors of the signal feature alarm type.

[0128] It can be seen that in the embodiment of the present application, by sending an alarm message to the radon detector to be tested through the signal transceiver module and testing the radon detector to be tested, when the alarm message generated by the radon detector to be tested cannot be obtained, it is determined that the test result of the radon detector to be tested is a failed test, and there is no need to perform the subsequent steps of testing according to the test distance, which improves the testing efficiency.

[0129] Through the method in the above application embodiment, it can be seen that the present invention determines the test result of the radon detector to be tested by obtaining multiple first test data, realizes the replacement of the traditional radon source with the americium-241 radiation source in the testing of the radon detector, and solves various problems brought by the traditional radon source. Different test processes are executed for different types of radon detectors to be tested, and the dark current test is performed on the radon detector to be tested, which improves the testing efficiency. By fusing the scenario-based environmental parameters and the dynamic weight mechanism to optimize the test parameters, the credibility of the test result is improved. By filtering the multiple first test data with the first preset value, the processing efficiency of the test equipment is improved.

[0130] Based on the description of the above configuration method embodiment, the present application also provides a test device for a radon detector, 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 α particles, and the signal transceiver module is used to collect the signal data generated during the operation of the radon detector or send a signal to the radon detector.

[0131] The test device for the radon detector can be a computer program (including program code) running in Figure 1 the test device 101 shown in Figure 2 and Figure 5 and Figure 6 shown in Figure 8 and is used to execute the methods shown in Figure 8 Please refer to For the structure schematic diagram of a test device for a radon detector provided in the embodiment of the present application, the test device 800 for the radon detector includes: An acquisition unit 801, configured to acquire the device parameters of the radon detector to be tested and determine the first test concentration of the radon detector to be tested according to the device parameters; A control unit 803, configured to control the distance between the americium-241 radiation source and the radon gas detector to be measured to meet the test distance, and control the americium-241 radiation source to be turned on; An acquisition unit 801, configured to acquire a plurality of first test data collected by the signal transceiver module from the radon gas detector to be measured during the period when the americium-241 radiation source is turned on, where the first test data is the electrical signal data corresponding to the alpha particles generated by the americium-241 radiation source; A determination unit 802, configured to determine the test result of the radon gas detector to be measured according to the plurality of first test data.

[0136] In a possible embodiment, before determining whether the values of the multiple first test data are within the preset value range, the determining unit 802 is further specifically configured to: determine the first test data lower than the first preset value among the multiple first test data as invalid data.
