Description

Technical Field

[0001] This application relates to the field of electromagnetic radiation measurement technology, such as methods, apparatus, systems and storage media for electromagnetic radiation measurement. Background Technology

[0002] Electromagnetic radiation is an energy wave formed by the propagation of in-phase and mutually perpendicular electric and magnetic fields in space. Its coverage is extremely broad, encompassing everything from radio waves and microwaves to infrared, visible light, ultraviolet light, and even X-rays and gamma rays. It includes natural radiation from the sun and lightning, as well as artificial radiation from human activities such as radio communication, broadcasting, power transmission, household appliances, and industrial equipment. With the rapid development of electrification and information technology in modern society, the widespread use of various electronic devices has significantly increased the number and intensity of electromagnetic radiation sources in the environment. Excessive or prolonged exposure to electromagnetic radiation in specific frequency bands may have potential effects on human health (such as interfering with bioelectrical signals and affecting the nervous system), and may also cause electromagnetic interference to the normal operation of precision electronic equipment, leading to malfunctions or performance degradation. Therefore, accurate and comprehensive measurement of electromagnetic radiation is of great significance.

[0003] In related technologies, electromagnetic signals of different frequency bands and electromagnetic signals of different measurement targets are all measured using a uniform electromagnetic radiation measurement procedure without differentiated processing based on frequency band characteristics, near-field and far-field distribution, antenna directivity, and environmental interference factors. This results in poor repeatability, large systematic errors, and insufficient comparability of measurement results in complex scenarios. Therefore, the scenario adaptability, frequency band specificity, operational standardization, and data reliability of electromagnetic radiation measurements still need to be improved.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a method, apparatus, system, and storage medium for electromagnetic radiation measurement, addressing the technical problem that the adaptability and accuracy of electromagnetic radiation measurement still need improvement.

[0007] In some embodiments, the method includes: The electromagnetic radiation measurement values ​​of a set number of targets are obtained through the current probe, wherein the current probe is matched with the current operating frequency of the target. Statistical tests were performed on the electromagnetic radiation measurements to obtain the tested electromagnetic radiation measurements. Based on the measured electromagnetic radiation values ​​after inspection, the electromagnetic radiation safety of the target under test is verified, and the corresponding verification results are output.

[0008] In some embodiments, obtaining electromagnetic radiation measurement values ​​for a set number of targets includes: When the target being measured is the environmental background of the measurement point, determine the current operating frequency within the first set area of ​​the measurement point, and determine the current probe and the current set sampling frequency that match the current operating frequency; Using the current probe, at the currently set sampling frequency, a first set number of electromagnetic radiation sampling values ​​are obtained, wherein the current probe is located on the support at the measurement point and is perpendicular to the ground.

If the second current absolute difference between the reacquired electromagnetic radiation measurement value and the recalculated second average measurement value is less than or equal to a set threshold, the acquired electromagnetic radiation measurement value is determined as the current electromagnetic radiation measurement value of the current measurement point.

[0012] In some embodiments, the statistical test of the electromagnetic radiation measurement values ​​further includes: If the second current absolute difference is greater than the set threshold, and the number of current measurements recorded corresponding to the current measurement point is less than or equal to the set number, the electromagnetic radiation measurement value of the target being measured is reacquired at the current measurement point corresponding to the current electromagnetic radiation measurement value. If the second current absolute difference is greater than the set threshold, and the current number of measurements is greater than the set number, an anomaly is marked and the current electromagnetic radiation measurement value is retained.

[0013] In some embodiments, the electromagnetic radiation safety verification of the target under test includes: With the target being measured as the environmental background of the measurement point, the electromagnetic radiation safety of the target is verified based on the electromagnetic radiation measurement value after verification, the location information of the measurement point, and the environmental information.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0022] Unless otherwise stated, the term "multiple" means two or more.

[0023] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0024] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0025] In this embodiment of the disclosure, different probes are used for electromagnetic radiation at different operating frequencies. The probes include one, two, or more of the following: an electromagnetic detection device, an inductive detection device, and a power density detection device. Furthermore, different targets under test also correspond to different electromagnetic radiation measurement operation procedures, which improves the adaptability and accuracy of electromagnetic radiation measurement. The acquired electromagnetic radiation measurement values ​​can also be statistically verified and anomaly handled, enabling automatic calibration of measurement results, error tracing, and risk warning, thereby enhancing data reliability.

[0026] Figure 1 This is a schematic diagram of a structure for an electromagnetic radiation measurement system provided in an embodiment of this disclosure. Figure 1 As shown, the system for electromagnetic radiation measurement includes: device body 100 and probe 200.

[0027] The probe 200 includes an electromagnetic detection device 210, an inductive detection device 220, and a power density detection device 230. The probe 200 can be a single physical probe, including the magnetic field detection device 210, electric field detection device 220, and power density detection device 230. Under the control of the device body 100, it can collect electromagnetic radiation measurements of the target object through one, two, or more of these detection devices. Alternatively, the probe 200 can be two or more physical probes. For example, one probe may include the magnetic field detection device 210 and the electric field detection device 220, while another probe may include both the electric field detection device 220 and the power density detection device 230; or, one probe may only include the power density detection device 230. Furthermore, the interface standard between each physical probe and the device body 100 is consistent. Therefore, the probe 200 can functionally include: a first probe and a second probe, wherein the first probe is used for magnetic field detection and electric field detection and can be applied in power frequency scenarios, and the second probe is used for power density detection, or for electric field detection and power density detection and can be applied in radio frequency scenarios.

[0028] The device body 100 can communicate with the probe 200 via wired or wireless connection, including a signal transmission unit 110. The output of the probe 200 can be wired or wirelessly connected to the input of the signal transmission unit 110. The device body 100 also includes a data processing unit 120 and a display unit 130. The output of the signal transmission unit 110 is connected to the input of the data processing unit 120, and the output of the data processing unit 120 is connected to the input of the display unit 130. Thus, the device body 100 can perform statistical verification, anomaly labeling, safety verification, and other data processing on the electromagnetic radiation measurement values ​​of the target obtained through the probe. Finally, the display unit 130 displays the safety verification results.

[0029] This system, which includes a probe and the main body of the device, is used for electromagnetic radiation measurement. It can measure the electromagnetic radiation of the target in various scenarios and perform corresponding safety verification. Figure 2 This is a schematic flowchart of a method for measuring electromagnetic radiation provided in an embodiment of this disclosure. Figure 2 As shown, the process of electromagnetic radiation measurement includes: Step 201: Obtain electromagnetic radiation measurement values ​​for a set number of targets using the current probe, wherein the current probe matches the current operating frequency of the target.

[0030] In this embodiment, the target under test can be the environmental background of the measurement point or a device, and the system for measuring electromagnetic radiation can measure both far-field and near-field electromagnetic radiation. Furthermore, the operating frequency corresponding to the target under test can also be different, corresponding to either the power frequency range or the radio frequency range. Specifically, when the target under test is the environmental background of the measurement point, the operating frequency range corresponding to the current operating frequency within the first set area of ​​the measurement point can be determined; when the target under test is a device, the operating frequency range corresponding to the current operating frequency of the device can be determined.

[0031] For example, when the target being measured is the environmental background of the measurement point, if there is a 110 kV substation or a high-voltage overhead line within a first set area with a radius of 50m centered on the measurement point, then the current operating frequency can be determined to belong to the power frequency range. If there is a 5G macro base station or an FM broadcast tower within a first set area with a radius of 100m centered on the measurement point, then the current operating frequency can be determined to belong to the radio frequency range. Of course, if there are both a 110 kV substation and a 5G macro base station within a first set area with a radius of 100m centered on the measurement point, then the corresponding operating frequency range can be determined to be either the power frequency range or the radio frequency range.

[0032] When the target being tested is a device, if the device is a microwave oven, base station, Wi-Fi router, etc., then the current operating frequency can be determined to belong to the radio frequency range. If the device is a charging pile, high-voltage switchgear, or induction cooker lamp, then the current operating frequency can be determined to belong to the power frequency range. Of course, if the device is a variable frequency air conditioner, elevator, etc., then the corresponding operating frequency range can be determined to be either the power frequency range or the radio frequency range.

[0033] In this embodiment of the disclosure, different electromagnetic radiation measurement processes correspond to different targets. In some embodiments, obtaining a set number of electromagnetic radiation measurement values ​​for the target includes: when the target is the environmental background of the measurement point, determining the current operating frequency in a first set area of ​​the measurement point, and determining the current probe and the current set sampling frequency that match the current operating frequency; obtaining a first set number of electromagnetic radiation sampling values ​​through the current probe at the current set sampling frequency, wherein the current probe is located on the support of the measurement point and is perpendicular to the ground.

[0034] When the current operating frequency within the first set area of ​​the measurement point is within the power frequency range, it is necessary to measure the electric field strength and magnetic induction intensity of the current scene. Therefore, the corresponding current probe can be a first probe, which is used for magnetic field detection and electric field detection, i.e., the first probe may include a magnetic field detection device and an electric field detection device. If the current operating frequency within the first set area of ​​the measurement point is within the radio frequency range, it is necessary to measure the power density, or electric field strength and power density of the current scene. Therefore, the corresponding current probe can be a second probe, which is used for power density detection, or for electric field detection and power density detection, i.e., the second probe includes a power density detection device, or a magnetic field detection device and a power density detection device. If the current operating frequency within the first set area of ​​the measurement point is within the power frequency range or the radio frequency range, the measurement can be performed first using the first probe, and then by using the second probe; alternatively, the measurement can be performed first using the second probe and then by using the first probe. Alternatively, the magnetic field detection device 210 and electric field detection device 220 in probe 200 can be activated first for measurement, followed by the electric field detection device 220 and power density detection device 230 in probe 200 for measurement. That is, regardless of whether the probe is a single physical probe or two or more physical probes, in the power frequency range, magnetic field and electric field detection can be performed through the probe, while in the radio frequency range, power density detection, or electric field and power density detection, can be performed through the probe.

[0035] Once a probe matching the current operating frequency has been identified, in some embodiments, the probe can be positioned to minimize local disturbances. Specifically, the probe can be fixed to a bracket at the measurement point. First, the bracket can be placed at the measurement point, and its height adjusted (e.g., 1.2m, 1.5m, or 1.8m). Then, the probe is fixed to the bracket, ensuring it is perpendicular to the ground. To further reduce signal interference, before performing electromagnetic radiation measurements with the probe, any metal objects, people, or other objects that could cause electromagnetic interference must be removed from the second designated area of ​​the probe. For example, if the bracket has metal parts, its height can be adjusted to keep the probe away from those metal parts.

[0036] When the target being measured is the environmental background of the measurement point, the sampling frequency corresponds to different operating frequencies. For example, if the current operating frequency is within the power frequency range, the corresponding current set sampling frequency can be 20 seconds / sample, while if the current operating frequency is within the radio frequency range, the corresponding current set sampling frequency can be 60 seconds / sample. The first set number can be 3, 4, or 5, or the first set number can also correspond to the current operating frequency. For example, if the current operating frequency is within the power frequency range, the first set number is 3, while if the current operating frequency is within the radio frequency range, the first set number is 5.

[0037] For example, when the target being measured is the environmental background of the measurement point, if the current operating frequency is within the power frequency range, the current probe can be identified as the first probe. The current sampling frequency is set to 20 seconds / sample, and the initial number of samples is 3. Therefore, by performing three measurements with a 20-second interval between each measurement using the first probe, the electromagnetic radiation sampling values ​​corresponding to each measurement can be obtained. Here, the electromagnetic radiation measurement values ​​obtained through the current probe include: 3 magnetic induction intensity values ​​and 3 electric field intensity values. If the current operating frequency is within the radio frequency range, the current probe can be identified as the second probe. The current sampling frequency is set to 60 seconds / sample, and the initial number of samples is 3. Therefore, by performing three measurements with a 60-second interval between each measurement using the second probe, the electromagnetic radiation sampling values ​​corresponding to each measurement can be obtained. Here, the electromagnetic radiation measurement values ​​obtained through the current probe include: 3 power density values, or 3 electric field intensity values ​​and 3 power density values.

[0038] In some embodiments, obtaining electromagnetic radiation measurement values ​​for a set number of targets includes: when the target is a device, determining the current operating frequency of the device in operation, and determining the current probe and sampling duration that match the current operating frequency; using the current probe, performing multiple measurements at multiple measurement points at different distances from the device, and obtaining the peak electromagnetic radiation value and the average electromagnetic radiation value within each sampling duration, wherein the current probe is directly facing the radiation source outlet of the device.

[0039] Similarly, if the target device is a power frequency device (i.e., the current operating frequency of the device in operation falls within the power frequency range), then the electric field strength and magnetic induction intensity in the current environment need to be measured, and the corresponding probe can be the first probe. If the device under test is a radio frequency (RF) device (i.e., the current operating frequency of the device in operation falls within the RF frequency range), then the power density, or electric field strength and power density in the current environment need to be measured, and therefore the corresponding probe can be the second probe. Furthermore, the current operating frequency of the target device varies; sometimes it matches the power frequency range, and sometimes it matches the RF range. Therefore, the probe is also matched to the current operating frequency. That is, when the current operating frequency corresponds to the power frequency range, the probe is the first probe; when the current operating frequency corresponds to the RF frequency range, the probe is the second probe.

[0040] As can be seen, regardless of whether the target being measured is the environmental background of the measurement point or the equipment, in some embodiments, determining the current probe that matches the current operating frequency includes: if the current operating frequency is within the power frequency range, determining a first probe as the current probe, wherein the first probe is used for magnetic field detection and electric field detection; if the current operating frequency is within the radio frequency range, determining a second probe as the current probe, wherein the second probe is used for power density detection.

[0041] When the target being measured is a device, in some embodiments, to determine the current probe that matches the current operating frequency, the current probe can be positioned directly opposite the device's source outlet. Simultaneously, the current probe can be placed at a measurement point at a predetermined distance from the device. This predetermined distance can be 1 cm, 10 cm, 50 cm, 1 m, 2 m, or 3 m, etc., and can be determined based on the device's performance, functions, etc. Furthermore, the sampling duration varies depending on the operating frequency. For example, if the current operating frequency is within the power frequency range, the corresponding sampling duration can be 20 seconds or 30 seconds, while if the current operating frequency is within the radio frequency range, the corresponding sampling duration can be 50 seconds or 60 seconds. This allows for a predetermined number of measurements at each measurement point, such as 3, 4, or 5 times. Alternatively, the predetermined number of measurements can correspond to the current operating frequency; for example, if the current operating frequency corresponds to the power frequency range, the predetermined number of measurements is 5, while if the current operating frequency corresponds to the radio frequency range, the predetermined number of measurements is 3.

[0042] For example, when the target being measured is equipment, if the current operating frequency is within the power frequency range, the current probe can be identified as the first probe. The first probe is fixed at a measurement point 10cm away from the equipment, with the first probe directly facing the radiation source outlet of the equipment. At this time, the equipment is in operation, and five measurements can be performed using the first probe, with each measurement corresponding to a sampling time of 20 seconds. This allows the acquisition of the peak value B of the magnetic induction intensity B within the corresponding 20 seconds of each measurement. p With average B a And the peak value of the electric field intensity E. p With average value E a Therefore, five peak values ​​B can be obtained at this measurement point. p With average B a and five peak E p With average value E a Then, the first probe is fixed at a measurement point 50cm away from the equipment, and the electromagnetic radiation at that point is measured. The process will not be described in detail here. Of course, when performing electromagnetic radiation measurements at multiple measurement points, antenna factor correction can be performed based on the corresponding near-field and far-field measurements.

[0043] When the target being measured is a device, if the current operating frequency falls within the appropriate radio frequency range, the current probe can be identified as the second probe. Similarly, the second probe is fixed at a measurement point 10cm away from the device, with the second probe directly facing the device's radiation source outlet. At this point, the device is in operation, and three measurements can be performed using the second probe. Each measurement corresponds to a sampling duration of 60 seconds, allowing the acquisition of the peak power density SD within the corresponding 60 seconds for each measurement. p With average S a Of course, if the second probe can also be used for electric field detection, then the peak value E of the electric field intensity E corresponding to that measurement point can also be obtained. p With average value E a Therefore, at this measurement point, the peak values ​​of the three power densities S can be obtained. p With average S a Or, the peak value of power density S. p With average S a And the peak value of the electric field intensity E. p With average value E a Then, the second probe is fixed at a measurement point 50cm away from the equipment, and the electromagnetic radiation at that point is measured. The process will not be described in detail here. Similarly, when performing electromagnetic radiation measurements at multiple measurement points, antenna factor correction can be performed based on the corresponding near-field and far-field measurements.

[0044] In some embodiments, the occurrence time of the peak value can also be recorded at the same time as the peak value is acquired, that is, the occurrence time of each electromagnetic radiation peak value is acquired.

[0045] Step 202: Perform statistical testing on the electromagnetic radiation measurement values ​​to obtain the tested electromagnetic radiation measurement values.

[0046] Different measurement processes are used for different targets. After obtaining a set number of electromagnetic radiation measurements, the obtained electromagnetic radiation measurements can be statistically tested. In some embodiments, the statistical test of electromagnetic radiation measurements includes: determining a first average measurement value corresponding to the electromagnetic radiation measurement value; if the first current absolute difference between the current electromagnetic radiation measurement value and the corresponding first average measurement value is greater than a set threshold, then re-acquiring the electromagnetic radiation measurement value of the target at the current measurement point corresponding to the current electromagnetic radiation measurement value; if the second current absolute difference between the re-acquired electromagnetic radiation measurement value and the second average measurement value determined after acquisition is less than or equal to a set threshold, then determining the acquired electromagnetic radiation measurement value as the current electromagnetic radiation measurement value of the current measurement point.

[0047] For example, when the target being measured is a device, five measurements were performed at a measurement point at a set distance from the device, and the obtained electromagnetic radiation measurements are shown in Table 1.

[0048]

[0049] Table 1 According to Table 1, the first electromagnetic average measurement value E is obtained. a-mean1 =(175+180+178+310+177) / 5=244 V / m. If the threshold is set to 20%, then in the fourth measurement, (310-244) / 244=27%. 27%>20%, therefore, this value is an outlier and needs to be measured again at this measurement point using the first probe to reproduce the corresponding E value. a If E a The value is 182 V / m, and the second electromagnetic average measurement value E after acquisition is... a-mean2 =(175+180+178+182+177) / 5=178.4 V / m. At this point, (182-178.4) / 178.4=2%, 2%<20%, therefore, 182 V / m can be determined as the E corresponding to the 4th measurement. a Of course, other electromagnetic radiation measurements can also be subjected to such statistical tests.

[0050] Of course, the reacquired electromagnetic radiation measurement value may also be an anomaly. In this case, further statistical testing can be performed. In some embodiments, the statistical testing of the electromagnetic radiation measurement value also includes: if the second current absolute difference is greater than a set threshold, and if the recorded number of current measurements corresponding to the current measurement point is less than or equal to a set number, then reacquire the electromagnetic radiation measurement value of the target at the current measurement point corresponding to the current electromagnetic radiation measurement value; if the second current absolute difference is greater than a set threshold, and if the current number of measurements is greater than a set number, then mark the cause of the anomaly and retain the current electromagnetic radiation measurement value.

[0051] Taking Table 1 as an example, an anomaly was found during the fourth measurement. If the corresponding measurement is performed again at the same measurement point using the first probe, the E value will be obtained. a The value is 288 V / m, and the second electromagnetic average measurement value E after acquisition is... a-mean2 =(175+180+178+288+177) / 5=199.6 v / m, corresponding to (288-199.6) / 199.6=44%, 44%>20%. In some embodiments, anomaly labeling can be performed directly, and the E value corresponding to the 4th measurement can be retained. a The value is 288 V / m. Alternatively, to further improve the accuracy of the measurement, the current number of measurements corresponding to the current measurement point can be recorded. For example, if the current number of measurements is 2 and the set number is 4, then the electromagnetic radiation measurement value of the target needs to be acquired again to obtain the corresponding average measurement value and the corresponding current absolute difference. If the current absolute difference is less than or equal to the set threshold, the acquired electromagnetic radiation measurement value can be determined as the corresponding current electromagnetic radiation measurement value. Otherwise, the current number of measurements increases to 3, 3 < 4, so the electromagnetic radiation measurement value of the target needs to be acquired again, recalculated and compared, until the current number of measurements is 5 and the calculated current absolute difference is still greater than the set threshold. Then, the cause of the anomaly can be marked and the current electromagnetic radiation measurement value can be retained.

[0052] The threshold can be set to 15%, 20%, or 25%, etc., and the number of measurements can be set to 3, 4, 5, or 6, etc., which can be determined by taking into account the operating frequency and equipment performance. During electromagnetic radiation measurements, location information and environmental information of the measurement point may be obtained. Therefore, anomaly cause labeling can mark the location information of the measurement point, environmental information, and the corresponding anomaly cause, such as meteorological conditions, equipment protective tripping, probe position slippage, sudden electromagnetic source intervention, etc.

[0053] Step 203: Based on the measured electromagnetic radiation values ​​after inspection, perform electromagnetic radiation safety verification on the target under test and output the corresponding verification results.

[0054] The state or designated agency has established relevant standards for electromagnetic radiation. Therefore, the measured electromagnetic radiation values ​​after testing can be compared with the corresponding standards to obtain the corresponding verification results.

[0055] In some embodiments, electromagnetic radiation safety verification of the target under test includes: when the target under test is the environmental background of the measurement point, electromagnetic radiation safety verification of the target under test is performed based on the electromagnetic radiation measurement value after verification, the location information of the measurement point and the environmental information; when the target under test is equipment, electromagnetic radiation safety verification of the target under test is performed based on the electromagnetic radiation measurement value after verification, the occurrence time of each electromagnetic radiation peak, and the status and operation information of the equipment.

[0056] For example: When the target being measured is the environmental background of the measurement point, and the current operating frequency falls within the power frequency range, the measured electromagnetic radiation values ​​after verification include: E = 0.18 kV / m, B = 0.8 μT. The obtained location and environmental information of the measurement point includes: 31.2304°N, 121.4737°E, altitude 1.5 m, 25 m horizontal distance from the 220 kV corridor, sunny, humidity 45%, temperature 28 °C, and no temporary construction. The corresponding public exposure radiation standard for power frequency is: E_limit = 4 V / m, B_limit = 100 μT. In this case, a single-factor determination can be performed: 0.18 / 4 = 4.5%, 0.8 / 100 = 0.8%. Since max(4.5%, 0.8%) = 4.5% < 100%, the verification result can be determined to be radiation safe. Alternatively, a multi-factor synthesis can be performed, for example: L... h = (E / E_limit) 2 +(B / B_limit) 2 If L h If the radiation level is less than the first radiation threshold, the verification result can be determined to include: radiation safety; if L h If the radiation level is greater than or equal to the first radiation threshold and less than the second radiation threshold, then the verification result can be determined, including: the radiation level needs to be considered; if L h If the radiation level is greater than or equal to the second radiation threshold, then the verification result can be definitively determined to include radiation hazard. Of course, other classifications can also be made, which will not be listed here.

[0057] Similarly, if the target device being tested is a device whose current operating frequency falls within the radio frequency range, such as a 2.45 GHz microwave oven, then the electromagnetic radiation measurement values ​​after testing will include: S p =0.94W / m 2 S a =0.49W / m 2 The peak occurrence times obtained include: t p=12s, 35s, 48s, that is, three peaks within a sampling time of 60s. The obtained equipment status and operation information includes: high power setting 100% full load, input power 1180 W, door gap 3 mm (compliant with factory specifications), and continuous stable operation for >5 min. The corresponding RF work exposure radiation standard is: S_limit = 10 W / m 2 Therefore, S p Since S_limit=0.94 / 10=9.4%<100%, the verification result can be determined to include radiation safety. Alternatively, S a / S_limit=0.49 / 10=4.9%<100%, equipment status detection can also be performed. Since the peak occurrence interval Δt = 23 s and 13 s is basically consistent with the magnetron anode thermal cycle of 30 s, and the deviation between the input power of 1180W and the rated power of 1200W is not large, the verification results are confirmed to include: safe to use.

[0058] As can be seen, in this embodiment of the disclosure, different probes are used for electromagnetic radiation at different operating frequencies, and different electromagnetic radiation measurement processes are used for different targets. In this way, not only is fully automated, full-band electromagnetic radiation safety verification achieved, but statistical verification and anomaly handling can also be performed, and automatic calibration, error tracing and risk warning of measurement results can be realized, enhancing data credibility and further improving the adaptability and measurement accuracy of electromagnetic radiation measurement.

[0059] The following describes the operation process in a specific embodiment, illustrating the electromagnetic radiation measurement process provided by the embodiments of the present invention.

[0060] In one embodiment of this disclosure, the system for electromagnetic radiation measurement can be as follows: Figure 1 As shown, the device includes the main body and probes. The probes can be divided into two physical probes: the first probe includes a magnetic field detection device 210 and an electric field detection device 220, while the second probe includes a power density detection device. Furthermore, the target being measured is the environmental background of the measurement point. Within a first set area with a radius of 100m centered on the measurement point, there are both a 110 kV substation and a 5G macro base station. Therefore, the current operating frequency corresponding to the target being measured may correspond to either the power frequency range or the radio frequency range. Combined with... Figure 1 , Figure 3 The process used for electromagnetic radiation measurement includes: Step 301: The device body determines the current probe that matches the current operating frequency.

[0061] Specifically, if the current operating frequency falls within the power frequency range, the first probe is selected as the current probe; if the current operating frequency falls within the radio frequency range, the second probe is selected as the current probe. Determining the current probe that matches the current operating frequency may specifically include establishing a signal connection with the current probe, for example, activating the connector or signal transmission unit corresponding to the current probe.

[0062] Step 302: When the current probe is located at the position corresponding to the measurement point to reduce local disturbance, the device body determines the current set sampling frequency that matches the current operating frequency in the first set area of ​​the measurement point, and determines the first set number that matches the current operating frequency.

[0063] Set up the bracket at the measurement point and adjust its height to 1.5m. Fix the current probe on the bracket, ensuring it is perpendicular to the ground and away from any metal parts of the bracket. Remove any metal objects, people, or other objects that could cause electromagnetic interference within 1 meter of the probe. This will determine the probe's position at the measurement point, minimizing local disturbance. If the current operating frequency corresponds to the power frequency range, the current sampling frequency is determined to be 30 seconds / cycle, with a first set number of 3. If the current operating frequency corresponds to the radio frequency range, the current sampling frequency is determined to be 60 seconds / cycle, with a first set number of 3.

[0064] Step 303: Using the current probe, the device body obtains a first set number of electromagnetic radiation sampling values ​​according to the currently set sampling frequency.

[0065] Similarly, if the current operating frequency is within the power frequency range, the electromagnetic radiation sampling values ​​may include three electric field intensities E and three magnetic flux density intensities B. If the current operating frequency is within the radio frequency range, the electromagnetic radiation sampling values ​​may include three power densities S.

[0066] Step 304: The device body determines the first average measurement value corresponding to the electromagnetic radiation sampling value, and obtains the first absolute difference between each electromagnetic radiation sampling value and the corresponding first average measurement value.

[0067] Step 305: Determine whether the first current absolute difference between the current electromagnetic radiation sample value and the corresponding first average measurement value is greater than the set threshold. If yes, proceed to step 306; otherwise, proceed to step 309.

[0068] An electromagnetic radiation sampling value can be determined as the current electromagnetic radiation sampling value according to the measurement time or a set sequence, and the corresponding first absolute difference can be the first current absolute difference.

[0069] Step 306: Using the current probe, the device body obtains the corresponding current electromagnetic radiation sampling value, and obtains the second average measurement value of the electromagnetic radiation sampling value including the current electromagnetic radiation sampling value, and the second current absolute difference between the current electromagnetic radiation sampling value and the second average measurement value.

[0070] The average of the current electromagnetic radiation sample value obtained again and other electromagnetic radiation sample values ​​can be used as the second average measurement value.

[0071] Step 307: Determine if the second current absolute difference is greater than the set threshold. If yes, proceed to step 308; otherwise, proceed to step 309.

[0072] Step 308: Mark the cause of the malfunction on the equipment body and retain the current electromagnetic radiation measurement value. Proceed to step 310.

[0073] Step 309: The device retains the current electromagnetic radiation measurement value. Proceed to step 310.

[0074] Step 310: Determine whether all first absolute differences should be checked for anomalies. If yes, proceed to step 311; otherwise, return to step 305.

[0075] Step 311: Based on the electromagnetic radiation measurement values ​​after inspection, the location information of the measurement point, and the environmental information, the equipment body performs electromagnetic radiation safety verification of the target under test and outputs the corresponding verification results.

[0076] As can be seen, in this embodiment, the device body can determine the current operating frequency of the target object corresponding to the power frequency magnetic field or radio frequency power density, and switch the first or second probe accordingly, matching the corresponding sampling frequency. After statistical verification and anomaly code annotation, the system can output the electromagnetic radiation safety verification conclusion on-site. This not only achieves automated measurement of environmental background field and multi-source mixed radiation, but also significantly improves the standardization, reliability, and accuracy of electromagnetic radiation measurement in complex electromagnetic environments.

[0077] In one embodiment of this disclosure, the system for electromagnetic radiation measurement can be as follows: Figure 1 As shown, the device includes the main body and probes. The probes can be divided into two physical probes: the first probe includes a magnetic field detection device 210 and an electric field detection device 220, while the second probe includes a power density detection device. Furthermore, the target being measured is a variable frequency air conditioner; therefore, the current operating frequency of the target may correspond to either the power frequency range or the radio frequency range. Combined with... Figure 1 , Figure 4 The process used for electromagnetic radiation measurement includes: Step 401: The device body determines the current probe that matches the current operating frequency.

[0078] Specifically, if the current operating frequency falls within the power frequency range, the first probe is designated as the current probe; if the current operating frequency falls within the radio frequency range, the second probe is designated as the current probe. Determining the current probe that matches the current operating frequency may specifically include establishing a signal connection with the current probe, for example, activating the connector or signal transmission unit corresponding to the current probe.

[0079] Step 402: The device body determines the sampling duration and the corresponding set number of measurements that match the current operating frequency.

[0080] If the current operating frequency corresponds to the power frequency range, then the corresponding sampling duration is 20 seconds, and the corresponding set measurement count is 5 times; if the current operating frequency corresponds to the radio frequency range, then the corresponding sampling duration is 60 seconds, and the corresponding set measurement count is 3 times.

[0081] Step 403: With the current probe located at the current measurement point and facing the outlet of the radiation source of the variable frequency air conditioner in operation, the device body performs electromagnetic radiation measurements at the current measurement point for a set number of measurements using the current probe, and obtains the electromagnetic radiation measurement value within the sampling time corresponding to each measurement.

[0082] The distance between the current measurement point and the radiation source of the variable frequency air conditioner is a set distance, which can be 1cm, 10cm, 50cm, or 1 meter. Here, the electromagnetic radiation measurement value includes the peak electromagnetic radiation value and the average electromagnetic radiation value. Similarly, if the current operating frequency corresponds to the power frequency range, the electromagnetic radiation sampling value can include 5 peak values ​​(B). p With average B a and 5 peak E p With average value E a If the current operating frequency corresponds to the radio frequency range, the electromagnetic radiation sampling value can include the peak values ​​of three power densities S0. p With average S a .

[0083] Step 404: The device body determines the first average measurement value of the electromagnetic radiation measurement value and obtains the first absolute difference between each electromagnetic radiation measurement value and the corresponding first average measurement value.

[0084] Step 405: Determine whether the first current absolute difference between the current electromagnetic radiation measurement value and the corresponding first average measurement value is greater than the set threshold. If yes, proceed to step 406; otherwise, proceed to step 410.

[0085] An electromagnetic radiation measurement value can be determined as the current electromagnetic radiation measurement value according to the measurement time or any other time, and the corresponding first absolute difference can be the first current absolute difference.

[0086] Step 406: Using the current probe, the device body obtains the corresponding current electromagnetic radiation measurement value, and obtains a second average measurement value of the electromagnetic radiation measurement value including the current electromagnetic radiation measurement value, and a second current absolute difference between the current electromagnetic radiation measurement value and the second average measurement value.

[0087] The average of the current electromagnetic radiation sample value obtained again and other electromagnetic radiation measurements can be used as the second average measurement value.

[0088] Step 407: Determine if the second current absolute difference is greater than the set threshold. If yes, proceed to step 408; otherwise, proceed to step 409.

[0089] Step 408: Is the recorded number of current measurements corresponding to the current measurement point > 4? If yes, proceed to step 409; otherwise, return to step 406.

[0090] Step 409: Mark the cause of the malfunction on the equipment body and retain the current electromagnetic radiation measurement value. Proceed to step 411.

[0091] Step 410: The device retains the current electromagnetic radiation measurement value. Proceed to step 411.

[0092] Step 411: Determine whether all first absolute differences should be checked for anomalies. If yes, proceed to step 412; otherwise, return to step 405.

[0093] Step 412: Determine if all measurement points have been measured? If yes, proceed to step 413; otherwise, return to step 403.

[0094] Step 413: The equipment body performs electromagnetic radiation safety verification of the target under test based on the electromagnetic radiation measurement value after inspection, the time of occurrence of each electromagnetic radiation peak, and the status operation information of the equipment, and outputs the corresponding verification results.

[0095] As can be seen, in this embodiment, based on the dual-band emission scenario of a variable frequency air conditioner, the device itself can automatically identify the current operating frequency and, at multiple measurement points, switch between the first and second probes in a coordinated manner, matching the corresponding sampling duration. After statistical verification and anomaly code annotation, the system can output electromagnetic radiation safety verification conclusions on-site. This not only achieves automated measurement of near-field leakage but also significantly improves the standardization, reliability, and accuracy of electromagnetic radiation measurements in complex electromagnetic environments.

[0096] Based on the above process for electromagnetic radiation measurement, a device for electromagnetic radiation measurement can be constructed.
