DETAILED DESCRIPTION

[0026] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various configurations. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0027] It should be noted that the term “comprising” will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0028] One aspect of the present application relates to an electromagnetic radiation monitoring method, which can provide electromagnetic radiation monitoring results in a timely manner even when the amount of electromagnetic radiation monitoring data is large, thereby achieving real-time monitoring of the electromagnetic environment.

[0029] It is worth noting that before the present application was filed, in the existing electromagnetic environment monitoring schemes, especially in the online monitoring schemes with spectrum analysis functions, the amount of spectrum analysis data is large, and the difficulty of collecting, transmitting and processing large amounts of data is relatively large. Due to the large amount of electromagnetic radiation monitoring data in the environment, if all spectrum field strength data of all frequency points within the detected spectrum range are uploaded to the electromagnetic radiation monitoring platform in real time after each detection, the transmission and platform processing time are long, and real-time monitoring cannot be performed.

[0030] In addition, the electromagnetic radiation spectrum field strength data for all frequency points is not intuitive for subsequent analysis or processing, and it is difficult to quickly and intuitively understand the electromagnetic radiation levels of different electromagnetic radiation sources. Generally speaking, the electromagnetic emission of an electromagnetic radiation source is a modulated broadband signal rather than a single-frequency signal. Taking 5G mobile communications as an example, the 5G frequency band of China Unicom and China Telecom operators has a bandwidth of 100MHz, while the 2.6GHz frequency band 5G frequency band of mobile operators has a bandwidth of 160MHz. Therefore, when receiving electromagnetic environment monitoring results, users may be more concerned about specific applications, such as the electromagnetic radiation level of a specific 5G base station or a specific telecom operator base station, and are not concerned about the electromagnetic field signal at a specific frequency point.

[0031] like Figure 1 As shown, the electromagnetic radiation monitoring method according to an embodiment of the present application may include the following steps:

[0032] S1. Obtain electromagnetic field signals at multiple frequency points in the environment.

[0033] In this step, the environment may refer to the area to be monitored for electromagnetic radiation, for example, it may be the environment in which the electromagnetic radiation monitoring system is set. In the present application, the electromagnetic field signal may refer to an electric field signal, a magnetic field signal, or both an electric field signal and a magnetic field signal, which may vary according to the monitoring frequency band. For example, in the electromagnetic environment monitoring of low frequency, medium and short wave, and broadcast frequency bands, the electromagnetic field signal includes both an electric field signal and a magnetic field signal; in the electromagnetic environment monitoring of the radio frequency microwave frequency band, the electromagnetic field signal may only refer to the electric field signal. As an example, the electromagnetic field signal may include an electromagnetic field strength value, such as an electric field strength and / or a magnetic field strength. When monitoring the low frequency band, the electromagnetic field signal may include a magnetic induction strength.

[0034] As an example, the step of obtaining electromagnetic field signals at multiple frequency points in the environment may include: S11, obtaining electromagnetic field signals at frequency points in multiple continuous frequency detection intervals in the environment, and integrating and storing the electromagnetic field signals at frequency points in multiple continuous frequency detection intervals as spectrum data; S12, obtaining electromagnetic field signals at multiple frequency points from the spectrum data.

[0035] Specifically, the spectrum of the electromagnetic radiation to be monitored may be divided into a plurality of continuous frequency detection intervals, and electromagnetic radiation detection may be performed for each of the plurality of continuous frequency detection intervals. For example, a plurality of frequency points may be selected in each frequency detection interval to detect the electromagnetic field signals of the plurality of frequency points. After the electromagnetic field signals of the frequency points in the plurality of continuous frequency detection intervals are detected, the electromagnetic field signals of all the frequency points in the plurality of continuous frequency detection intervals may be integrated and stored as spectrum data, so that the electromagnetic field signals of the plurality of frequency points in the environment may be obtained from the spectrum data. For example, the electromagnetic field signals of a plurality of predetermined frequency points may be selected from the spectrum data, or the electromagnetic field signals of all the frequency points in the spectrum data may be used.

[0036] For example, Figure 2 As shown, the electromagnetic radiation monitoring system according to the embodiment of the present application may include multiple electromagnetic radiation monitors with continuous frequency detection intervals, for example, it may include a low-frequency electromagnetic radiation monitor, a medium- and short-wave electromagnetic radiation monitor, and a radio-frequency microwave electromagnetic radiation monitor. The low-frequency electromagnetic radiation monitor can detect electromagnetic field signals in the environment in the frequency detection interval of 10 Hz to 100 kHz, the medium- and short-wave electromagnetic radiation monitor can detect electromagnetic field signals in the environment in the frequency detection interval of 100 kHz to 30 MHz, and the radio-frequency microwave electromagnetic radiation monitor can detect electromagnetic field signals in the environment in the frequency detection interval of 30 MHz to 6 GHz. The specific structure of the electromagnetic radiation monitoring system according to the embodiment of the present application will be described in detail below.

[0037] S2. Extracting the electromagnetic field signal of a first frequency point in a desired frequency range from among a plurality of frequency points, and calculating the comprehensive radiation field strength value of the desired frequency range.

[0038] In this step, the desired frequency range may refer to a preset frequency range of interest, and the first frequency point may refer to a frequency point within the desired frequency range. As an example, the desired frequency range may be set according to the frequency range of known electromagnetic applications / services, such as the frequency range of medium wave stations 525kHz to 1605kHz, the short wave frequency range 2.2MHz to 26MHz, the mobile operator 5G frequency band 2515MHz to 2675MHz, the Unicom operator 5G frequency band 3.5GHz to 3.6GHz, the telecom operator 5G frequency band 3.4GHz to 3.5GHz, etc. The desired frequency range may be a common electromagnetic application frequency band.

[0039] There may be multiple desired frequency bands, and for each desired frequency band, frequency selection measurement may be performed. Specifically, the electromagnetic field signal of the first frequency point in the desired frequency band among multiple frequency points may be determined, and the field strength values ​​of all first frequency points may be accumulated to calculate the comprehensive radiation field strength value of the desired frequency band. Here, the comprehensive radiation field strength value may be the result of the square root of the sum of the squares of the electromagnetic field strength values ​​of all first frequency points. The comprehensive radiation field strength value may be calculated for each desired frequency band, and the comprehensive radiation field strength value may represent the electromagnetic radiation level of the desired frequency band.

[0040] In addition, a frequency selection measurement list of comprehensive radiation field strength values ​​may be established based on the comprehensive radiation field strength values ​​of the expected frequency bands, and the frequency selection measurement list may include all preset expected frequency bands and their corresponding comprehensive radiation field strength values.

[0041] As an example, step S2 may include: adjusting the size of the electromagnetic field signal of the first frequency point in the desired frequency band among multiple frequency points, and filtering the adjusted electromagnetic field signal to filter out the noise signal; converting the filtered electromagnetic field signal into a digital signal, and performing secondary filtering; and calculating the comprehensive radiation field strength value of the desired frequency band based on the electromagnetic field signal after the secondary filtering.

[0042] Specifically, the magnitude of the electromagnetic field signal at a first frequency point in a desired frequency range among a plurality of frequency points may be adjusted, for example, the electromagnetic field signal may be attenuated.

[0043] In one example, the electromagnetic field signal may be an analog signal, and the adjusted electromagnetic field signal as the analog signal may be filtered to filter out noise signals in the detected electromagnetic field signal; however, in another example, the electromagnetic field signal may also be a digital signal.

[0044] After the first filtering, the electromagnetic field signal can be converted into analog-to-digital or digital-to-analog, and the converted signal can be filtered twice. In this way, the comprehensive field strength value can be calculated based on the electromagnetic field signal after the two filtering processes.

[0045] For example, Figure 3As shown, the electromagnetic radiation monitoring system may include an electromagnetic radiation monitor and a central control device, and the central control device may receive detection data from the electromagnetic radiation monitor and control the operation of the electromagnetic radiation monitor. The central control device may include an attenuator 210, an analog filter 220, a sampler 230, an analog-to-digital converter 240, a digital filter 250, an FFT processor 260, and a data processor 270. The attenuator may receive an electromagnetic field signal sent from a sensor of the electromagnetic radiation monitor, attenuate it, and output the attenuated signal to the analog filter. The analog filter filters the electromagnetic field signal once to filter out the noise signal, and outputs the filtered signal to the sampler. The sampler may sample multiple electromagnetic field signals to obtain discrete signals from the analog signal, and output the sampled signals to the analog-to-digital converter. The analog-to-digital converter converts the sampled discrete signal into a digital signal, and outputs the digital signal to the digital filter. The digital filter performs secondary filtering on the signal and sends the filtered signal to the FFT processor and the data processor. The FFT processor can perform fast Fourier transform on the filtered signal, and the data processor can calculate the comprehensive radiation field strength value based on the electromagnetic field signal after fast Fourier transform.

[0046] S3. Send electromagnetic field signals at multiple frequency points at a first time interval, and send a comprehensive radiation field strength value of a desired frequency range at a second time interval.

[0047] In this step, the first time interval and the second time interval may be the same or different. In one example, the second time interval may be smaller than the first time interval.

[0048] Specifically, the measured spectrum data may be sent only at the time point of the set first time interval, for example, the spectrum data may be sent or uploaded to the server, and at the time point of the set second time interval, only the comprehensive radiation field strength value of the desired frequency segment may be sent, for example, the frequency selection measurement list described above may be sent. As an example, the amount of data of the comprehensive radiation field strength value of the desired frequency segment sent at the time point of the second time interval may be less than 1 / 1000 of the amount of data of the spectrum data sent at the time point of the first time interval.

[0049] In the case of sending the comprehensive radiation field strength value of the desired frequency band, the amount of data sent is greatly reduced, which reduces the requirements for the transmission bandwidth of the electromagnetic radiation monitoring system and improves the data transmission rate. In addition, in the case of sending the comprehensive radiation field strength value of the desired frequency band, the data processing pressure of subsequent processing devices such as the electromagnetic radiation monitoring platform can be reduced. In particular, when receiving and processing the detection data of multiple monitoring environments at the same time, the processing speed can be greatly improved. In addition, since the comprehensive radiation field strength value can characterize the overall level of electromagnetic radiation in the desired frequency band, sending the comprehensive radiation field strength value of the desired frequency band can facilitate intuitively obtaining the electromagnetic radiation situation of the desired frequency band of interest, such as the electromagnetic radiation level of a specific electromagnetic radiation facility.

[0050] In addition, the spectrum data and the comprehensive field strength value are sent at the first time interval and the second time interval respectively, which on the one hand meets the requirements of frequency-selective online monitoring of electromagnetic radiation, and on the other hand also meets the measurement of occasional or unknown signals (signals outside the expected frequency band such as the frequency band in the frequency selective measurement list).

[0051] Specifically, frequency selective measurement is feasible for electromagnetic applications with known fixed electromagnetic emission frequency bands, but within the entire monitoring spectrum, there are some occasional or unknown electromagnetic radiation signals, which may not belong to the working frequency of known applications / services, and cannot be processed by the method of integrating known frequency bands to calculate the comprehensive field strength value. Sending the complete monitoring spectrum data at the time point of the first time interval can ensure that the electromagnetic radiation level of the desired frequency band of interest can be obtained in real time and quickly, while processing and analyzing occasional or unknown electromagnetic radiation signals, understanding the spectrum distribution of environmental electromagnetic radiation signals, and avoiding missing electromagnetic field signal data at frequency points / frequency bands outside the desired frequency band.

[0052] In addition, the electromagnetic radiation monitoring method according to the embodiment of the present application may further include: S4, extracting the electromagnetic field signal of a second frequency point outside the desired frequency range from multiple frequency points, and sending the electromagnetic field signal of the second frequency point at a third time interval.

[0053] In this step, the second frequency point may refer to a frequency point outside the expected frequency range, and the second frequency point may be the accidental or unknown frequency point described above. The third time interval may be the same as or different from the first time interval and / or the second time interval. In one example, the third time interval may be greater than the first time interval, and the second time interval may be less than the first time interval.

[0054] Specifically, the electromagnetic field signal at a second frequency point outside the expected frequency band can be extracted, and the electromagnetic field signal at the second frequency point can be sent as a separate data list or data packet, which can facilitate targeted processing and analysis of electromagnetic field signal data at occasional or unknown frequency points.

[0055] Another aspect of the present application relates to an electromagnetic radiation monitoring system. Corresponding components in the electromagnetic radiation monitoring system can perform various steps / operations in the electromagnetic radiation monitoring method described above.

[0056] The electromagnetic radiation monitoring system according to the embodiment of the present application may include an electromagnetic radiation monitor 100 and a central control device 200 .

[0057] The electromagnetic radiation monitor 100 can detect electromagnetic field signals at multiple frequency points in the environment where the electromagnetic radiation monitor 100 is located, and send the detected electromagnetic field signals to the central control device 200 .

[0058] The electromagnetic radiation monitor 100 may have a spectrum analysis function. In one example, the electromagnetic radiation monitor 100 may be composed of an antenna and a frequency selective measuring instrument. The antenna may receive electromagnetic field signals in the environment and transmit the received electromagnetic field signals to the frequency selective measuring instrument. The frequency selective measuring instrument may perform spectrum analysis on the electromagnetic field signals. Spectrum analysis may refer to detecting electromagnetic field / electric field signals in the environment and outputting digital data of the spectrum based on the detected electromagnetic field / electric field signals. In another example, the electromagnetic radiation monitor 100 may be an electromagnetic field probe. The electromagnetic field probe may receive electromagnetic field signals in the environment and perform spectrum analysis on the electromagnetic field signals. For example, Figure 6 , Figure 7 and Figure 8 As shown, the electromagnetic radiation monitor 100 may be a three-axis omnidirectional electromagnetic field probe.

[0059] like Figure 2 As shown, there may be multiple electromagnetic radiation monitors 100, and the frequency detection intervals of the multiple electromagnetic radiation monitors 100 may be continuous.

[0060] For example, the electromagnetic radiation monitor 100 may include a low-frequency electromagnetic radiation monitor 101, a medium- and short-wave electromagnetic radiation monitor 102, and a radio-frequency microwave electromagnetic radiation monitor 103, wherein the low-frequency electromagnetic radiation monitor 101 can detect electromagnetic field signals in the environment in a frequency detection range of 10 Hz to 100 kHz, the medium- and short-wave electromagnetic radiation monitor 102 can detect electromagnetic field signals in the environment in a frequency detection range of 100 kHz to 30 MHz, and the radio-frequency microwave electromagnetic radiation monitor 103 can detect electromagnetic field signals in the environment in a frequency detection range of 30 MHz to 6 GHz.

[0061] In addition, Figure 2 In the example of , the electromagnetic radiation monitor 100 may further include a broadcast electromagnetic radiation monitor (not shown), which may detect electromagnetic field signals in the environment within a frequency detection interval of 100 kHz to 138 MHz.

[0062] Although it is described above that there may be multiple electromagnetic radiation monitors 100, the embodiments of the present application are not limited thereto. Figure 4 As shown, only one electromagnetic radiation monitor 100 may be provided. Here, according to the requirements of the frequency detection range, the electromagnetic radiation monitor 100 may be any one of a low-frequency electromagnetic radiation monitor 101, a medium- and short-wave electromagnetic radiation monitor 102, a radio-frequency microwave electromagnetic radiation monitor 103, and a broadcast electromagnetic radiation monitor.

[0063] exist Figure 6 , Figure 7 and Figure 8 In the example of FIG. 1 , the electromagnetic radiation monitor 100 may include any one or more of a low-frequency electromagnetic field probe, a medium- and short-wave electromagnetic field probe, and a radio-frequency broadband electromagnetic field probe.

[0064] The central control device 200 may include a processor, a first timer, and a second timer, and the electromagnetic radiation monitor 100 may send the detected electromagnetic field data to the processor of the central control device 200 .

[0065] The processor can extract the electromagnetic field signal of the frequency point within the desired frequency range from the multiple frequency points to determine the comprehensive radiation field strength value of the desired frequency range. Specifically, the processor can execute the steps described above in the embodiment of the electromagnetic radiation monitoring method to calculate the comprehensive radiation field strength value. In addition, the processor can establish a frequency selection measurement list based on the comprehensive field strength value of the desired frequency range.

[0066] The timer may send a timing signal for controlling the operation of the processor, and the processor may send the electromagnetic field data from the electromagnetic radiation monitor in response to the timing signal sent by the timer.

[0067] Specifically, the processor can send electromagnetic field data of multiple frequency points to the data management server in response to a first trigger signal sent by a first timer, and the processor can send the comprehensive radiation field strength values ​​of the electromagnetic field data of frequency points within the expected frequency range among the multiple frequency points to the data management server in response to a second trigger signal sent by a second timer.

[0068] In addition, the processor may also extract the electromagnetic field signal of a second frequency point outside the desired frequency range from among the multiple frequency points, and send the electromagnetic field signal of the second frequency point at a third time interval.

[0069] In the case where there are multiple electromagnetic radiation monitors 100 and the frequency detection intervals of the multiple electromagnetic radiation monitors 100 are continuous, the processor can integrate and store the electromagnetic field signals of the frequency points in the multiple continuous frequency detection intervals as spectrum data, and obtain the electromagnetic field signals of the multiple frequency points from the spectrum data. Here, the processor may include the FFT processor and the data processor described above, but is not limited thereto, and may also include other processors to send the electromagnetic field data to the data management server.

[0070] In addition, the central control device 200 may also include the attenuator, analog filter, sampler, analog-to-digital converter and digital filter described above. The central control device 200 may be connected to the spectrum antenna via a communication connection line such as a radio frequency cable and an optical fiber to receive electromagnetic field data from the spectrum antenna, and obtain spectrum data and a comprehensive field strength value after processing analog and digital signals. The functions and connection methods of the above components have been specifically described in the above method embodiment and will not be repeated here.

[0071] like Figure 2 and Figure 5 As shown, the central control device 200 may be a computer host having strong data processing capabilities; Figure 6 , Figure 7 and Figure 8 As shown, the central control device 200 may also be a portable safety box, which is convenient to carry and move.

[0072] In the case where the electromagnetic radiation monitor 100 is composed of an antenna and a frequency selective measuring instrument, the central control device 200 may also include an Ethernet port interface or a universal serial bus interface (USB interface). Here, the Ethernet port interface is, for example, a network interface that can be used to connect to Ethernet, such as an RJ45 interface, etc. The antenna and the frequency selective measuring instrument are respectively connected to the processor of the central control device 200 through the Ethernet port interface or the USB interface to communicate with the processor. Figure 4 As shown, the antenna and the frequency selection measuring instrument can be connected to the network port interface or USB interface of the central control device 200 via a radio frequency line. However, the present application is not limited thereto, and the central control device 200 can also communicate with the processor via a mobile communication network.

[0073] In the case where the electromagnetic radiation monitor 100 includes an electromagnetic field sensor, the central control device 200 may also include an optical fiber interface, and the electromagnetic field sensor may be connected to the processor of the central control device 200 through the optical fiber interface to communicate with the processor. Figure 4 As shown, the electromagnetic field sensor can be connected to the optical fiber interface of the central control device 200 via an optical fiber.

[0074] The electromagnetic radiation monitoring system may further include a support assembly 300, and the support assembly 300 may include a support rod 301 and a support base 302. Figure 2 and Figure 5 As shown, the electromagnetic radiation monitor 100 is fixed to the first end of the support rod 301, and the second end of the support rod 301 is fixed to the support base 302. The support rod 301 may include insulating material to avoid electromagnetic interference to the detection process of the electromagnetic radiation monitor 100. For example, the support rod 301 may be a glass fiber tube.

[0075] The support base 302 can be used to place the support assembly 300 on the ground. Figure 2 and Figure 5 In the example shown, the electromagnetic radiation monitoring system may be a fixed system, and the support base 302 may be fixed to the ground by means of fastening means such as bolts, so that the electromagnetic radiation monitor 100 is fixedly installed relative to the ground. Figure 6 , Figure 7 and Figure 8 In another example shown, the electromagnetic radiation monitoring system can be a mobile system, and the electromagnetic radiation monitor 100 can be detachably connected to the support rod 301. The second end of the support rod 301 can be detachably connected to the support base 302, and the support base 302 can be formed as a T-shaped bracket to stably support the support rod 301 when the support base 302 is not fixed to the ground. In addition, the electromagnetic radiation monitor 100 can be fixed to the support rod 301 by a retaining member 303, and the retaining member 303 can be, for example, a clamp.

[0076] In addition, Figure 6 , Figure 7 and Figure 8 In the example of, the support rod 301 may include a first rod portion 3011 and a second rod portion 3012. The first rod portion 3011 and the second rod portion 3012 are detachably connected so that the support rod 301 can be disassembled into at least two parts, thereby facilitating the storage and movement of the support rod 301. For example, the first rod portion 3011 and the second rod portion 3012 may be connected by a fastener 3013 such as a hand screw. The electromagnetic radiation monitor 100 may be fixed on the first rod portion 3011, and the second rod portion 3012 may be detachably connected to the support base 302. However, the connection method of the first rod portion 3011 and the second rod portion 3012 is not limited thereto, for example, the first rod portion 3011 and the second rod portion 3012 may also be sleeved with each other, so that one of the first rod portion 3011 and the second rod portion 3012 may be extended and retracted relative to the other, thereby facilitating the storage and movement of the support rod 301.

[0077] The electromagnetic radiation monitoring system may further include a data management server, and the central control device 200 may send the electromagnetic field data from the electromagnetic radiation monitor to the data management server for analysis and processing by the data management server. The data management server may be, for example, an electromagnetic radiation monitoring platform.

[0078] like Figure 4 As shown, the electromagnetic radiation monitoring system may further include a communication module 400, which may be responsible for the communication of the central control device 200, such as the communication between the central control device 200 and the data management server. As an example, the communication module 400 may be a wireless communication module. The communication mode of the communication module 400 may be, for example, WiFi, Bluetooth, cellular network, etc.

[0094] For the low frequency band (10 Hz to 100 kHz), the desired frequency band may include two frequency bands: 10 Hz to 1 kHz and 1 kHz to 100 kHz.

[0095] For the medium and short wave frequency bands (100 kHz to 30 MHz), the desired frequency bands may include two frequency bands: medium wave broadcasting (525 kHz to 1605 kHz) and short wave broadcasting (2.2 MHz to 26 MHz).

For example, the electromagnetic radiation monitoring system may also include two electromagnetic radiation monitors 100, and the two electromagnetic radiation monitors 100 may be a three-axis omnidirectional medium- and short-wave electromagnetic field probe and a three-axis omnidirectional radio frequency broadband electromagnetic probe, respectively.

[0107] The electromagnetic radiation monitor 100 of the electromagnetic radiation monitoring system can be powered by the battery box 505, and the central control device 200 can be powered by the battery box 505 or AC220.

The central control device 200 can obtain the spectrum data collected by the electromagnetic radiation monitor, calculate the data according to the expected frequency band (for example, the measurement frequency band set in the frequency selection measurement list), and after the calculation of the items to be measured is completed, the comprehensive radiation field strength value of the expected frequency band can be temporarily stored locally, and the spectrum data can also be temporarily stored locally. The uploading of the comprehensive radiation field strength value data and the spectrum data both use timer interrupts. When the timer interrupt is triggered, the most recently temporarily stored comprehensive radiation field strength value data and spectrum data are uploaded to achieve the timed uploading of the comprehensive radiation field strength value data and spectrum data. Here, the timing time of the timer (eg, the first time interval, the second time interval, and the third time interval) may be configured through an external instruction or a preset program.
