Description

TECHNICAL FIELD

[0001] The present application relates to the field of general data processing technology of radon detectors related to the Internet, and in particular to a radon detector detection method based on a granite radon source and related devices. BACKGROUND

[0002] Radon is a radioactive element in a gaseous state at normal temperature and pressure. It is generally formed near the surface of soil or rock containing uranium and diffuses into the surrounding air. Radon is colorless and odorless, which means that humans cannot easily detect its presence and concentration. Therefore, radon detectors are needed in indoor, industrial and mining scenarios to ensure personnel safety.

[0003] However, the detection performance of radon detectors in the prior art is usually detected by an HD-6 numerical control radon chamber. The HD-6 numerical control radon chamber is generally used for scientific research and has high cost and maintenance costs. Meanwhile, the HD-6 numerical control radon chamber uses radium 226 as a solid radon source, which also has a high radon source cost. Therefore, the detection cost of radon detectors in the prior art is high. SUMMARY

[0004] To solve the above problems, the present application provides a radon detector detection method based on a granite radon source and related devices. The present application is advantageous in solving the problem of high detection cost of radon detectors.

[0005] In a first aspect, the present application provides a radon detector detection method based on a granite radon source, applied to a controller in a radon detector detection system. The radon detector detection system further includes a granite radon source, a test space, and a ventilation fan between the granite radon source and the test space. The method comprises: determining a first target concentration, which is not less than the alarm concentration of the measured radon detector; controlling the ventilation fan to act on the granite radon source to make the radon concentration in the test space meet the first target concentration; obtaining a first signal generated by the measured radon detector detecting the radon in the test space; and detecting the detection performance of the measured radon detector according to the first signal.

[0006] As can be seen, in the present application, the radium 226 radon source with high cost is replaced by the granite radon source with low cost to detect the radon detector, and then the first signal generated by the radon detector is obtained. There is no need to build a numerical control radon chamber and use a high-cost radium 226 radon source, thereby reducing the detection cost of the radon detector.

[0007] With reference to the first aspect, in a possible implementation, the radon detector detection system further includes a ventilation channel, a first radon detector and a second radon detector; the ventilation channel is configured to connect the granite radon source and the test space, a ventilation fan is located in the ventilation channel, the first radon detector is configured to detect the radon concentration in the test space, and the second radon detector is configured to detect the radon concentration in the ventilation channel; the method of controlling the ventilation fan to act on the granite radon source to make the radon concentration in the test space meet the first target concentration includes: obtaining a second signal obtained by the second radon detector detecting radon in the ventilation channel; determining a first target rotating speed of the ventilation fan according to the first target concentration and the second signal; controlling the ventilation fan to operate according to the first target rotating speed; obtaining a third signal obtained by the first radon detector detecting radon in the test space; and if the third signal indicates that the radon concentration in the test space meets the first target concentration, turning off the ventilation fan.

[0008] It can be seen that, in the embodiments of the present application, by introducing the ventilation channel and the multiple radon detectors, in combination with real-time signal acquisition and fan rotating speed control, the radon concentration in the test space is accurately improved and stably maintained, thereby ensuring the accuracy and repeatability of the radon detector detection process, and reducing the operation complexity.

[0009] With reference to the first aspect, in a possible implementation, the method of determining the first target rotating speed of the ventilation fan according to the first target concentration and the second signal includes: determining a first gas generation rate of the granite radon source according to the third signal; and determining the first target rotating speed according to the quotient of the first gas generation rate divided by the first target concentration.

[0010] It can be seen that, in the embodiments of the present application, by combining real-time determination and calculation of the radon generation rate, the rotating speed of the ventilation fan is accurately controlled, thereby quickly and stably improving the radon concentration in the test space to the target value, reducing the debugging time and human error in the traditional method, and improving the reliability and efficiency of the radon detector detection.

[0011] With reference to the first aspect, in a possible implementation, the method of detecting the detection performance of the measured radon detector according to the first signal includes: if the first signal indicates that the measured radon detector meets the alarm condition, determining that the detection performance of the measured radon detector is qualified; and if the first signal indicates that the measured radon detector does not meet the alarm condition, determining that the detection performance of the measured radon detector is unqualified.

[0012] With reference to the first aspect, in a possible implementation, if the first signal indicates that the measured radon gas detector does not meet the alarm condition, the method further includes: determining a second target concentration, the second target concentration being greater than the first target concentration; controlling the ventilation fan to act on the granite radon source to increase the radon gas concentration in the test space to the second target concentration; obtaining a second signal detected by the measured radon gas detector from the radon gas in the test space; if the second signal indicates that the measured radon gas detector meets the alarm condition, determining that the unqualified reason of the measured radon gas detector is numerical deviation; and if the second signal indicates that the measured radon gas detector does not meet the alarm condition, determining that the unqualified reason of the measured radon gas detector is element failure.

[0013] It can be seen that, in the embodiments of the present application, the cause diagnosis of the unqualified radon gas detector is realized by establishing a hierarchical concentration test mechanism, which can effectively distinguish the two different types of defects of numerical deviation and element failure, improve the completeness of the detection process, and provide clear direction guidance for subsequent product improvement and maintenance, thereby significantly improving the practicability of the detection system.

[0014] With reference to the first aspect, in a possible implementation, the controlling of the ventilation fan to act on the granite radon source to increase the radon gas concentration in the test space to the second target concentration includes: determining a simulation test environment of the measured radon gas detector, the simulation test environment including an indoor environment or a mine environment; and controlling the ventilation fan to increase the radon gas concentration in the test space to the second target concentration based on the simulation test environment.

[0015] It can be seen that, in the embodiments of the present application, by distinguishing the simulation test environment and adopting a differentiated control strategy, the detection process is closer to the actual use scene of the measured radon gas detector, thereby improving the practicability and reliability of the detection result.

[0016] With reference to the first aspect, in a possible implementation, if the simulation test environment is an indoor environment, the controlling of the ventilation fan to increase the radon gas concentration in the test space to the second target concentration based on the simulation test environment includes: obtaining a fourth signal detected by the first radon gas detector from the radon gas in the current test space; determining a second gas generation rate and a gas attenuation rate of the granite radon source according to the fourth signal and the third signal; generating a second target speed and a third target speed according to the first preset time, the second target concentration, the second gas generation rate, and the gas attenuation rate, the third target speed being greater than the second target speed; and controlling the ventilation fan to operate at the second target speed and increase the speed of the ventilation fan to the third target speed within the first preset time.

[0017] It can be seen that, in the embodiments of the present application, by establishing the gradual concentration control strategy of indoor environment simulation, not only the radon accumulation process in the actual use scene is truly reproduced, but also the accurate control of the radon concentration in the test space is realized through the real-time calculation of the gas generation rate and the decay rate, and the reliability and practicability of the detection result are improved.

[0018] Through the method in the above embodiments, it can be seen that, by replacing the radium226 radon source with a lower cost with the granite radon source for radon detector detection, the detection cost of the radon detector is reduced. By introducing the ventilation channel and the multiple radon detectors, the accuracy and repeatability of the radon detector detection process are ensured. By establishing the hierarchical concentration test mechanism, the practicability of the detection system is improved. By distinguishing the simulation test environment and adopting the differentiated control strategy, the practicability and reliability of the detection result are improved.

DETAILED DESCRIPTION

[0039] In order to enable persons skilled in the art to better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only 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 persons skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0041] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily independent or alternative embodiments to each other. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0042] The embodiments of the present application will be described below in combination with the drawings.

[0043] Embodiment one: please refer to Figure 1 , Figure 1 An application scenario of a radon gas detector detection method based on a granite radon source provided by the embodiments of the present application is shown in the figure. The application scenario 100 includes a controller 101, a granite radon source 102, a test space 103, a ventilation fan 104, and a measured radon gas detector 105.

[0044] The controller 101, the granite radon source 102, the test space 103, and the ventilation fan 104 belong to a radon detector detection system. The controller 101 is configured to coordinate and manage the granite radon source 102, the test space 103, and the ventilation fan 104, so as to realize detection on the detected radon detector 105.

[0045] The granite radon source 102 specifically includes a 0.5 m3 sealed acrylic glass box, and the bottom of the sealed acrylic glass box is provided with about 250 kg of natural granite gravel.

[0046] In addition, in order to prevent the decrease of air tightness caused by bearing deformation, the sealed acrylic glass box uses acrylic glass with a thickness of 1.5 cm. A stainless steel skeleton is designed inside the box body as a support. Double-layer silicone rubber strips with a thickness of 0.8 cm are used to paste the combined parts and the door opening part to prevent air leakage.

[0047] The test space 103 includes at least one shelf for placing at least one detected radon detector 105.

[0048] The ventilation fan 104 is located between the granite radon source 102 and the test space 103. When the ventilation fan 104 is turned on, the granite radon source 102 is connected to the test space 103, and the radon concentration in the test space 103 is increased. When the ventilation fan 104 is turned off, the granite radon source 102 is disconnected from the test space 103, and the radon concentration in the test space 103 is maintained.

[0049] In the embodiment of the present application, the controller 101 determines a first target concentration, and the first target concentration is not less than the alarm concentration of the detected radon detector 105.

[0050] Specifically, the first target concentration here refers to the concentration of radon, and the specific value corresponds to the detected radon detector 105, for example, the alarm concentration of the detected radon detector 105 is 400 Bq / m 3 , and the corresponding first target concentration is 400 Bq / m 3 .

[0051] The controller 101 controls the ventilation fan 104 to act on the granite radon source 102, so that the radon concentration in the test space 103 meets the first target concentration.

[0052] Specifically, the controller 101 controls the ventilation fan 104 to act on the granite radon source 102, so that the radon concentration in the test space 103 is increased to meet the first target concentration, that is, the radon concentration in the test space 103 is not less than the first target concentration, or the radon concentration in the test space 103 is a concentration interval determined according to the first target concentration.

[0053] The controller 101 acquires a first signal obtained by the measured radon detector 105 detecting radon in the test space 103.

[0054] After the radon in the test space 103 meets the first target concentration, the controller 101 acquires a first signal obtained by the measured radon detector 105 detecting radon in the test space 103. The first signal includes an electrical signal generated by the measured radon detector 105 according to the detected radon concentration, an alarm signal generated according to the radon concentration, and the like.

[0055] The controller 101 detects the detection performance of the measured radon detector 105 according to the first signal.

[0056] The detection of the detection performance specifically detects whether the detection accuracy of the measured radon detector 105 is qualified, whether the detection function is normal, whether the alarm function is normal, and the like through the first signal.

[0057] It can be seen that in the embodiment of the present application, the radium226 radon source with high cost is replaced by the granite radon source with low cost to detect the radon detector, and then the first signal generated by the radon detector is acquired. The numerical control radon chamber and the radium226 radon source with high cost are not needed, and the detection cost of the radon detector is reduced.

[0058] Please refer to Figure 2 , Figure 2 A flowchart of a radon detector detection method based on a granite radon source provided in the embodiment of the present application can be implemented based on the application scenario 100 as shown in Figure 1 , and includes steps S201-S204 as shown in Figure 2 .

[0059] S201: The controller determines a first target concentration, and the first target concentration is not less than the alarm concentration of the measured radon detector.

[0060] S202: The controller controls the ventilation fan to act on the granite radon source, so that the radon concentration in the test space meets the first target concentration.

[0061] Specifically, after the controller controls the ventilation fan to start, the ventilation fan causes the air in the granite radon source and the test space to flow, so that the radon concentration in the test space meets the first target concentration.

[0062] Optionally, the radon detector detection system further comprises a ventilation channel, a first radon detector and a second radon detector. The ventilation channel is used to connect the granite radon source and the test space. The ventilation fan is located in the ventilation channel. The first radon detector is used to detect the radon concentration in the test space. The second radon detector is used to detect the radon concentration in the ventilation channel. The control of the ventilation fan acting on the granite radon source to make the radon concentration in the test space meet the first target concentration comprises: obtaining a second signal obtained by the second radon detector detecting the radon in the ventilation channel; determining a first target rotating speed of the ventilation fan according to the first target concentration and the second signal; controlling the ventilation fan to operate according to the first target rotating speed; obtaining a third signal obtained by the first radon detector detecting the radon in the test space; and if the third signal represents that the radon concentration in the test space meets the first target concentration, then closing the ventilation fan.

[0063] Specifically, the following describes the specific process of controlling the ventilation fan acting on the granite radon source to make the radon concentration in the test space meet the first target concentration. In the embodiment of the present application, the radon detector detection system further comprises a ventilation channel, a first radon detector and a second radon detector.

[0064] For example, please refer to Figure 3 , Figure 3 A structure diagram of a radon detector detection system provided by the embodiment of the present application is shown in the figure, which comprises a controller (not shown in the figure), a granite radon source, a first radon detector, a second radon detector, a ventilation channel, a ventilation fan and a test space. The ventilation channel is used to connect the granite radon source and the test space. The ventilation fan is located in the ventilation channel. The operation of the ventilation fan promotes the flow of radon from the granite radon source to the test space. The first radon detector is used to detect the radon concentration in the test space. The second radon detector is used to detect the radon concentration in the ventilation channel, thereby realizing the multi-point monitoring of the radon concentration.

[0065] In the control process, first, a second signal obtained by the second radon detector detecting the radon in the ventilation channel is obtained. The signal represents the real-time radon concentration in the ventilation channel, reflecting the radon generation and diffusion state of the granite radon source. The first target rotating speed of the ventilation fan is determined according to the first target concentration and the second signal. Specifically, the rotating speed of the fan can be calculated by a predefined algorithm to ensure that the radon can be efficiently delivered to the test space and reach the target concentration. For example, based on the radon generation rate, the channel attenuation characteristics and the target concentration, the rotating speed value is determined by using a formula or a lookup table.

[0066] Then, the ventilation fan is controlled to operate according to the first target rotation speed, and the rotation speed of the fan is adjusted to regulate the radon flow. Meanwhile, a third signal obtained by the first radon detector detecting radon in the test space is acquired, and the third signal is used to verify whether the radon concentration in the test space is close to or reaches the first target concentration. If the third signal represents that the radon concentration in the test space meets the first target concentration (for example, the concentration value is within the target range, such as ±50 Bq / m³), the ventilation fan is turned off to stop the input of radon and maintain the stable concentration state of the test space.

[0067] Exemplarily, the second radon detector and the first radon detector are professional devices such as rad7 radon detectors, which communicate with the PC control system through a wireless protocol to realize real-time data acquisition and automatic control. Through such a multi-point monitoring and feedback control mechanism, the rotation speed of the fan can be accurately adjusted, the target concentration can be quickly reached, human intervention can be reduced, and the reliability and efficiency of the test can be improved.

[0068] As can be seen, in the embodiments of the present application, by introducing the ventilation channel and the multiple radon detectors, and combining real-time signal acquisition and fan rotation speed control, the accurate increase and stable maintenance of the radon concentration in the test space are realized, so as to ensure the accuracy and repeatability of the radon detector detection process, and reduce the operation complexity.

[0069] Optionally, determining the first target rotation speed of the ventilation fan according to the first target concentration and the second signal comprises: determining a first gas generation rate of the granite radon source according to the third signal; and determining the first target rotation speed according to a quotient of the first gas generation rate divided by the first target concentration.

[0070] Specifically, when calculating the first target rotation speed, the first gas generation rate of the granite radon source is first determined according to the third signal. The third signal is obtained by the first radon detector and represents the real-time radon concentration in the test space. By analyzing the trend of the signal over time, the radon generation rate of the granite radon source can be calculated. For example, based on the physical principle of radon decay, by monitoring the growth curve of the radon concentration in a closed environment, the first gas generation rate is calculated.

[0071] Further, by using professional radon measurement equipment such as rad7 for high-frequency sampling (for example, once every 10 minutes), and by the PC control system fitting the data to dynamically update the gas generation rate.

[0072] The first target rotation speed is determined according to a quotient of the first gas generation rate divided by the first target concentration. Exemplarily, the first target rotation speed satisfies the following formula (1):

[0073]

[0074] Wherein N is the first target rotation speed, G is the first gas generation rate, and k is the quotient of the first gas generation rate divided by the first target concentration. qK is a fan flow constant, C is a first target concentration, k n is a concentration decay coefficient of radon in the ventilation channel.

[0075] The second signal is acquired by a second radon detector, representing the radon concentration in the ventilation channel, and is used to assist in verifying the gas generation rate and adjusting the calculation parameters. Through this calculation method based on real-time signal feedback, the characteristics of the granite radon source can be dynamically adapted (such as differences in uranium content or environmental temperature effects), improving the accuracy of the speed control.

[0076] As can be seen, in the embodiments of the present application, by combining real-time determination and calculation of the radon generation rate, precise control of the ventilation fan speed is achieved, thereby quickly and stably increasing the test space radon concentration to the target value, reducing the debugging time and human error in the traditional method, and improving the reliability and efficiency of the radon detector detection.

[0077] S203: The controller acquires a first signal obtained by a measured radon detector detecting radon in a test space.

[0078] The controller acquires the first signal obtained by the radon detector detecting radon in the test space by connecting with the measured radon detector.

[0079] S204: The controller detects the detection performance of the measured radon detector according to the first signal.

[0080] The detection performance of the measured radon detector is detected by the controller, specifically including that the controller judges whether the first signal corresponds to the first target concentration to realize detection of the detection performance of the measured radon detector.

[0081] Embodiment two: The above application embodiment provides a radon detector detection method of a granite radon source focusing on realizing a test environment of a specific radon concentration. Based on this, in terms of focusing on the test of the measured radon detector, the present application embodiment also provides a more detailed radon detector detection method based on a granite radon source.

[0082] Please refer to Figure 4 , Figure 4 The flowchart of another radon detector detection method based on a granite radon source provided by the present application embodiment can be implemented based on the application scenario 100 as shown in Figure 1 , and includes steps S401-S405 as shown in Figure 4 .

[0083] S401: The controller determines a first target concentration, and the first target concentration is not less than the alarm concentration of the measured radon detector.

[0084] S402: The controller controls the ventilation fan to act on the granite radon source, so that the radon concentration in the test space meets a first target concentration.

[0085] S403: The controller acquires a first signal obtained by the measured radon detector detecting radon in the test space.

[0086] For detailed description of steps S401-S403, please refer to steps S201-S203 and other related contents, which will not be repeated here.

[0087] S404: If the first signal indicates that the measured radon detector meets the alarm condition, the controller determines that the detection performance of the measured radon detector is qualified.

[0088] Specifically, if the first signal indicates that the measured radon detector meets the alarm condition, i.e., the measured radon detector correctly identifies the radon concentration reaching or exceeding its preset alarm threshold, it is determined that the detection performance of the measured radon detector is qualified. This indicates that the detector can normally respond under standard test conditions and has basic radon detection capability.

[0089] S405: If the first signal indicates that the measured radon detector does not meet the alarm condition, the controller determines that the detection performance of the measured radon detector is unqualified.

[0090] Specifically, if the first signal indicates that the measured radon detector does not meet the alarm condition, i.e., the detector fails to respond to radon reaching the alarm concentration, it is determined that the detection performance of the measured radon detector is unqualified. This indicates that the detector may have problems such as insufficient sensitivity, calibration deviation or hardware failure.

[0091] Optionally, if the first signal indicates that the measured radon detector does not meet the alarm condition, the method further comprises: determining a second target concentration, the second target concentration being greater than the first target concentration; controlling the ventilation fan to act on the granite radon source to raise the radon concentration in the test space to the second target concentration; acquiring a second signal obtained by the measured radon detector detecting radon in the test space; if the second signal indicates that the measured radon detector meets the alarm condition, determining that the unqualified reason of the measured radon detector is numerical deviation; and if the second signal indicates that the measured radon detector does not meet the alarm condition, determining that the unqualified reason of the measured radon detector is element failure.

[0092] Specifically, in the embodiments of the present application, the further processing process when the first signal indicates that the measured radon detector does not meet the alarm condition is explained.

[0093] When the first signal indicates that the measured radon detector fails to generate the expected alarm response to the radon gas reaching the first target concentration, the system performs further diagnosis procedures. First, a second target concentration is determined, which is greater than the first target concentration, for example, the second target concentration can be set to 1.5 times or more of the first target concentration to provide stronger test stimulation.

[0094] Then the ventilation fan is controlled to act on the granite radon source, and the radon concentration in the test space is raised from the current level to the second target concentration by adjusting the fan speed. This process can be achieved by increasing the fan speed or prolonging the running time, which can be specifically referred to the control method based on gas generation rate and concentration feedback in the foregoing embodiments.

[0095] The second signal detected by the measured radon detector in the raised concentration environment is obtained, and the signal is judged: if the second signal indicates that the measured radon detector meets the alarm condition at this time, it is determined that the unqualified reason of the measured radon detector is numerical deviation. This indicates that the detector can respond to radon gas, but its sensitivity or calibration has deviation, resulting in failure to alarm normally at the standard test concentration.

[0096] If the second signal indicates that the measured radon detector still does not meet the alarm condition, i.e., it still has no response under the obviously increased radon concentration, it is determined that the unqualified reason of the measured radon detector is element failure. This indicates that the detector may have fundamental problems such as hardware damage, sensor failure or circuit failure.

[0097] As can be seen, in the embodiments of the present application, the cause diagnosis of the unqualified radon detector is realized by establishing a hierarchical concentration test mechanism, which can effectively distinguish the two different types of defects of numerical deviation and element failure, improve the completeness of the detection process, and provide clear direction guidance for subsequent product improvement and maintenance, significantly improving the practicability of the detection system.

[0098] Optionally, the control of the ventilation fan acting on the granite radon source to raise the radon concentration in the test space to the second target concentration comprises: determining a simulated test environment of the measured radon detector, the simulated test environment comprising an indoor environment or a mine environment; and controlling the ventilation fan to raise the radon concentration in the test space to the second target concentration based on the simulated test environment.

[0099] Specifically, in the embodiments of the present application, the specific process of controlling the ventilation fan acting on the granite radon source to raise the radon concentration in the test space to the second target concentration is explained, which involves the determination of the simulated test environment and the selection of the control strategy.

[0100] Firstly, a simulation test environment of the radon gas detector to be tested is determined, and the simulation test environment includes an indoor environment or an industrial and mining environment. The indoor environment usually refers to a living place such as a family or an office, and the radon gas concentration of the indoor environment changes relatively gently. The industrial and mining environment refers to an industrial place such as a mine or a tunnel, and the radon gas concentration of the industrial and mining environment may fluctuate rapidly and the average value is relatively high. By simulating different environments, the performance of the radon gas detector to be tested in an actual use scenario can be more comprehensively evaluated.

[0101] Based on the determined simulation test environment, the radon gas concentration in the test space is increased to a second target concentration by controlling the ventilation fan according to different characteristics (for example, a concentration rising curve, a rising speed, and the like).

[0102] As can be seen, in the embodiments of the present application, by distinguishing the simulation test environment and adopting a differential control strategy, the detection process is closer to the actual use scenario of the radon gas detector to be tested, and the practicability and reliability of the detection result are improved.

[0103] Optionally, if the simulation test environment is an indoor environment, increasing the radon gas concentration in the test space to the second target concentration based on the simulation test environment includes: obtaining a fourth signal detected by the first radon gas detector from the radon gas in the current test space; determining a second gas generation rate and a gas decay rate of the granite radon source according to the fourth signal and the third signal; generating a second target rotating speed and a third target rotating speed according to the first preset time, the second target concentration, the second gas generation rate and the gas decay rate, the third target rotating speed being greater than the second target rotating speed; and controlling the ventilation fan to operate at the second target rotating speed and to increase the rotating speed of the ventilation fan to the third target rotating speed within the first preset time.

[0104] Specifically, in the embodiments of the present application, the simulation test environment is an indoor environment, that is, the target use scenario of the radon gas detector to be tested is a living place such as a family or an office.

[0105] Firstly, a fourth signal detected by the first radon gas detector from the radon gas in the current test space is obtained, and the signal represents the real-time radon gas concentration state in the test space. In combination with the previously obtained third signal (representing the radon gas concentration of the test space in the previous stage), the second gas generation rate and the gas decay rate of the granite radon source under the current condition are determined by analyzing the concentration change relationship between the two signals.

[0106] For example, based on the radon gas dynamic balance principle, the net generation rate is calculated by dividing the concentration change amount by the time interval, and in combination with the known physical decay characteristics, the actual generation rate and the environmental decay rate of the radon source are separated.

[0107] Then the second target rotating speed and the third target rotating speed are generated according to the first preset time, the second target concentration, the second gas generation rate and the gas attenuation rate, wherein the third target rotating speed is greater than the second target rotating speed. The first preset time simulates the natural process of radon accumulation in the indoor environment. The second target rotating speed corresponds to a lower rotating speed in the initial stage of concentration increase, and the third target rotating speed corresponds to a higher rotating speed when the target concentration is approached.

[0108] Finally, the ventilation fan is controlled to run at the second target rotating speed, and the rotating speed of the ventilation fan is smoothly increased to the third target rotating speed within the first preset time. The test environment is closer to the actual use scenario.

[0109] As can be seen, in the embodiments of the present application, by establishing the gradual concentration control strategy of the indoor environment simulation, not only the radon accumulation process in the actual use scenario is truly reproduced, but also the accurate control of the radon concentration in the test space is realized through real-time calculation of the gas generation rate and the attenuation rate, thereby improving the reliability and practicability of the detection result.

[0110] Optionally, if the simulated test environment is a mine environment, the radon concentration in the test space is increased to the second target concentration based on the simulated test environment control of the ventilation fan, comprising: obtaining a fourth signal detected by the first radon detector in the current test space; determining the second gas generation rate and the gas attenuation rate of the granite radon source according to the fourth signal and the third signal; generating the fourth target rotating speed and the fifth target rotating speed according to the second preset time, the second target concentration, the second gas generation rate and the gas attenuation rate, wherein the fifth target rotating speed is greater than the fourth target rotating speed, and the second preset time is less than the first preset time; and controlling the ventilation fan to run at the fourth target rotating speed and increasing the rotating speed of the ventilation fan to the fifth target rotating speed within the second preset time.

[0111] Specifically, in the embodiments of the present application, the simulated test environment is a mine environment, that is, the target use scenario of the measured radon detector is an industrial place such as a mine or a tunnel.

[0112] Firstly, a fourth signal detected by the first radon detector in the current test space is obtained, which represents the real-time radon concentration state in the test space. Combined with the previously obtained third signal (representing the radon concentration of the test space in the previous stage), the second gas generation rate and the gas attenuation rate of the granite radon source under the current condition are determined by analyzing the concentration change relationship between the two signals.

[0113] Then the fourth target rotating speed and the fifth target rotating speed are generated according to the second preset time, the second target concentration, the second gas generation rate and the gas attenuation rate, wherein the fifth target rotating speed is greater than the fourth target rotating speed, and the second preset time is significantly less than the first preset time.

[0114] Finally, the ventilation fan is controlled to operate at a fourth target speed, and the speed of the ventilation fan is rapidly increased to a fifth target speed within a second preset time. This acceleration control strategy simulates the feature that the radon concentration in the industrial and mining environment may suddenly increase, and can effectively test the response performance of the detector under the condition of rapid change of the concentration.

[0115] It can be seen that, in the embodiments of the present application, the rapid concentration increase strategy of the industrial and mining environment simulation is established, the feature that the radon concentration in the industrial and mining environment and the like changes sharply is truly reproduced, the performance evaluation of the radon detector is more comprehensive, and the reliability and practicability of the detection result are improved.

[0116] Optionally, the method further comprises: obtaining a fifth signal detected by the second radon detector in the ventilation channel; if the fifth signal represents that the radon concentration in the ventilation channel is lower than a first concentration threshold, controlling the ventilation fan to stop operating; continuously monitoring the fifth signal, and if the fifth signal represents that the radon concentration in the ventilation channel is higher than a second concentration threshold, restarting the ventilation fan; wherein the first concentration threshold and the second concentration threshold are determined based on a dynamic peak value range of the gas generation rate of the granite radon source.

[0117] Specifically, in the embodiments of the present application, the further optimization process of controlling the ventilation fan to increase the radon concentration in the test space to the second target concentration based on the simulated test environment is explained.

[0118] First, a fifth signal detected by the second radon detector in the ventilation channel is obtained, which reflects the radon concentration state in the ventilation channel in real time. By monitoring the signal, the system can understand the real-time radon production state of the granite radon source and the distribution of radon in the channel.

[0119] If the fifth signal represents that the radon concentration in the ventilation channel is lower than the first concentration threshold, it indicates that the current radon source radon production rate is low or the radon accumulation in the channel is insufficient, at this time the ventilation fan is controlled to stop operating, avoiding the low concentration radon being transported to the test space, and ensuring the accuracy of the test concentration.

[0120] The system continuously monitors the fifth signal, and when the fifth signal represents that the radon concentration in the ventilation channel is higher than the second concentration threshold, it indicates that the radon production rate of the radon source has recovered and the radon accumulation in the channel is sufficient, at this time the ventilation fan is restarted to transport the high-quality concentration radon to the test space.

[0121] The first concentration threshold and the second concentration threshold are determined based on a dynamic peak interval of a gas generation rate of the granite radon source. Through long-term monitoring of the radon production characteristics of the granite radon source, it is found that the gas generation rate of the granite radon source fluctuates periodically, and the system identifies the high generation rate stage, and sets the first concentration threshold and the second concentration threshold accordingly, to ensure that the radon gas is transported when the radon source has the highest radon production efficiency.

[0122] Exemplarily, please refer to Figure 5 , Figure 5 The radon gas generation concentration change curve of the marble radon source provided by the embodiment of the application shows the trend of the change of the concentration of radon gas with time. It can be seen that, by determining the first concentration threshold and the second concentration threshold, the transmission of radon gas to the test space is temporarily stopped after the radon gas generation rate of the marble radon source decreases, so that the radon gas generation of the marble radon source is kept in a higher generation rate interval, thereby improving the radon gas generation efficiency.

[0123] It can be seen that, in the embodiment of the application, by establishing a fan start-stop control mechanism based on the concentration monitoring of the ventilation channel and dynamically adjusting the concentration threshold according to the radon source generation characteristics, the optimization management of radon gas supply is realized, thereby improving the radon gas generation efficiency.

[0124] Embodiment three: the above-mentioned application embodiment provides a radon gas detector detection method based on a granite radon source. The above-mentioned application embodiment also includes a ventilation channel. Based on this, the embodiment of the application further provides a more detailed radon gas detector detection method based on a granite radon source without including a ventilation channel.

[0125] Exemplarily, please refer to Figure 6 , Figure 6 Another structural diagram of a radon gas detector detection system provided by the embodiment of the application is provided.

[0126] The radon gas detector detection system includes a controller (not shown in the figure), a marble radon source, a test space, and a ventilation fan. Under the premise that the ventilation fan is turned on, the marble radon source and the test space are in gas flow, so that the radon gas generated by the marble radon source is introduced into the test space.

[0127] Further, the radon gas detector detection system further includes a circulating fan, which is used to promote the circulation of air in the test space to make the radon gas in the test space uniformly distributed.

[0128] Exemplarily, please refer to Figure 7 , Figure 7 A flowchart of another radon gas detector detection method based on a granite radon source provided by the embodiment of the application is provided. The method can be implemented based on the application scenario 100 shown in Figure 1 , and includes steps S701-S705 as shown in Figure 7 .

[0129] S701: The controller determines a first target concentration, which is not less than an alarm concentration of the radon gas detector to be tested.

[0130] S702: The controller starts the ventilation fan and obtains a sixth signal obtained by the first radon gas detector detecting radon gas in the test space.

[0131] Specifically, the controller first starts the ventilation fan to make the radon gas generated by the granite radon source enter the test space through the ventilation channel. At the same time, the controller obtains the sixth signal obtained by the first radon gas detector detecting radon gas in the test space, which reflects the change of the radon gas concentration in the test space in real time.

[0132] S703: If the sixth signal represents that the radon gas in the test space meets the first target concentration, the controller stops the ventilation fan.

[0133] Specifically, the controller continuously monitors the sixth signal and compares it with the preset first target concentration. When the sixth signal represents that the radon gas concentration in the test space meets the first target concentration, i.e., the actual concentration reaches or enters the error range allowed by the target concentration (such as ±50 Bq / m³), the controller stops the ventilation fan and stops the radon gas supply.

[0134] As can be seen, in the embodiments of the present application, by establishing an automatic control system based on real-time concentration feedback, the maintenance of the radon gas concentration in the test space is realized, and the detection cost of the radon gas detector is further reduced.

[0135] S704: The controller obtains a first signal obtained by the radon gas detector to be tested detecting radon gas in the test space.

[0136] S705: The controller detects the detection performance of the radon gas detector to be tested according to the first signal.

[0137] The detailed description of steps S701, S704 and S705 can be found in steps S201-S204 and related contents, which will not be repeated here.

[0138] As can be seen from the method in the above embodiments, by replacing the radium226 radon source with the granite radon source with lower cost for the detection of the radon gas detector, the detection cost of the radon gas detector is reduced. By introducing the ventilation channel and the multiple radon gas detectors, the accuracy and repeatability of the radon gas detector detection process are ensured. By establishing a hierarchical concentration test mechanism, the practicability of the detection system is improved. By distinguishing the simulation test environment and adopting a differentiated control strategy, the practicability and reliability of the detection result are improved.
