[0065] The embodiment of the present application provides a signal detection method, referring to Figure 1As shown, the method is applied to a signal detection device, and the method comprises the following steps:
[0066] Step 101: Determine m points to be analyzed in the space where the signal detection device is currently located.
[0067] Wherein, m is an integer greater than or equal to 1, and the signal detection device does not need to be installed with a user identification card, and is used to support frequency scanning of full-band wireless communication signals provided by at least one operator.
[0068] In an embodiment of the present application, the signal detection device may be a device with computing capabilities, may be a signal detection device body with computing capabilities, or may be a computing device with a communication connection to the signal detection device, such as a computer device, a server device, etc. The point to be analyzed may be a location point where the signal strength distribution may be the strongest in the current space. m may be a fixed empirical value, or a variable empirical value determined based on the spatial characteristics of the current space, or an empirical value set by the user based on actual conditions. The signal detection device is currently placed in a spatial place where the signal distribution provided by each operator needs to be detected, and the spatial place is the current space. The signal detection device obtains the spatial distribution information of the current space, analyzes the acquired spatial distribution information of the current space, and determines that m points to be analyzed are obtained.
[0069] Step 102: Determine the current position of the signal detection device in the current space.
[0070] In the embodiment of the present application, the signal detection device can obtain the location information where it is currently placed, so that the location information of the signal detection device in the current space can be analyzed to determine the current location of the signal detection device in the current space. The current location of the signal detection device can be expressed in latitude and longitude coordinates.
[0071] Step 103: Determine n signal base stations corresponding to the signals covered in the current space.
[0072] Wherein, n is an integer greater than or equal to 1.
[0073] In the embodiment of the present application, the signal detection device determines the signal base station to which the signal covered in the current space belongs, and obtains n signal base stations.
[0074] Step 104: Acquire actual signal parameters of wireless signals transmitted by n signal base stations at the current location.
[0075] In the embodiment of the present application, the signal detection device collects actual signal parameters of wireless signals transmitted by n signal base stations that can be received at the current location.
[0076] Step 105: Based on the actual signal parameters corresponding to the n signal base stations, the n signal base stations, the current location and the m points to be analyzed, determine the target signal parameters of each point to be analyzed corresponding to each signal base station.
[0077] In an embodiment of the present application, based on the positional relationship between n signal base stations and the current position and m points to be analyzed, the theoretical signal parameters of the signals of the n signal base stations at the current position and the m points to be analyzed can be determined, and then the actual signal parameters of the n signal base stations at the current position and the theoretical signal parameters of the n signal base stations at the current position and the m points to be analyzed are analyzed to obtain the target signal parameters of each signal base station at each point to be analyzed.
[0078] Step 106: Output the target signal parameters of each to-be-analyzed point corresponding to each signal base station.
[0079] In an embodiment of the present application, the target signal parameters at each point to be analyzed corresponding to each signal base station are output, and can be output on a display screen corresponding to the signal detection device, or can be output to a third-party display device that has a communication connection with the signal detection device or the signal detection equipment and has a display screen. In this way, the user can intuitively see the target signal parameters of each point to be analyzed corresponding to each signal base station, so as to perform subsequent operations according to the target signal parameters, such as placing a signal shielding device, or adjusting the placement position of the signal detection device.
[0080] The signal detection method provided in the embodiment of the present application determines, through a signal detection device, m points to be analyzed in the space where the signal detection device is currently located, determines the current position of the signal detection device in the current space, and determines n signal base stations corresponding to the signals covered in the current space, then obtains the actual signal parameters of the wireless signals transmitted by the n signal base stations at the current position, and then determines the target signal parameters of each point to be analyzed corresponding to each signal base station based on the actual signal parameters corresponding to the n signal base stations, the n signal base stations, the current position and the m points to be analyzed, and finally outputs the target signal parameters of each point to be analyzed corresponding to each signal base station. In this way, by simultaneously detecting and analyzing the signals of n signal base stations near the current space in the current space, the target signal parameters at the m points to be analyzed in the current space of the signal detection device can be quickly determined, so that the signal distribution in the current space can be determined, which solves the current problem of low efficiency in wireless communication signal detection in special occasions, and proposes a method for wireless communication signal detection in special occasions, which effectively simplifies the process of wireless communication signal detection in special occasions, shortens the time consumed by wireless communication signal detection in special occasions, and improves the detection efficiency of wireless communication signals in special occasions.
[0081] Based on the foregoing embodiments, an embodiment of the present application provides a signal detection method, which is applied to a signal detection device. The method includes the following steps:
[0082] Step 201: Determine m points to be analyzed in the space where the signal detection device is currently located.
[0083] Wherein, m is an integer greater than or equal to 1, and the signal detection device does not need to be installed with a user identification card, and is used to support frequency scanning of full-band wireless communication signals provided by at least one operator.
[0084] In the embodiment of the present application, there is no need to install a subscriber identity module (SIM) card in the signal detection device, which can detect signals of various frequency bands of wireless signals such as the second-generation wireless telephone technology (2G), the third-generation mobile communication technology (3G), the fourth-generation wireless telephone technology (4G), the fifth-generation mobile communication technology (5G), the wireless network communication technology (Wi-Fi), and Bluetooth provided by various communication operators.
[0085] Take the signal detection device as the signal detection device body, and the current space as the classroom where signal detection is currently required as an example for explanation. The user can input the spatial environment information such as the length, width and height of the classroom into the signal detection device. In some application scenarios, the signal detection device can also obtain image content with classroom space information as spatial environment information through image acquisition devices such as cameras, so as to construct the current space in three dimensions, obtain the three-dimensional space information of the current space, and determine m points to be analyzed from the three-dimensional space information of the current space. In some application scenarios, when analyzing the signal distribution in the current space, it is only necessary to know the signal strength near the edge of the current space, because according to the principle of signal attenuation, the closer to the center of the current space, the weaker the signal strength.
[0086] Step 202: Determine the current position of the signal detection device in the current space.
[0087] In the embodiment of the present application, the current location can be a location selected by the user based on experience in the current space for placing the signal detection device, or it can be a location recommended to the user by the signal detection device after analyzing the current space, and the user places the signal detection device based on the recommended location. The signal detection device can determine the location of the signal detection device in the current space based on the positioning device set inside itself to obtain the current location.
[0088] Step 203: determine n signal base stations corresponding to the signals covered in the current space.
[0089] Wherein, n is an integer greater than or equal to 1.
[0090] In the embodiment of the present application, the signal detection device can determine through signal detection that the current space is covered by n signal base stations belonging to different wireless signal providing operators.
[0091] Step 204: Acquire actual signal parameters of wireless signals transmitted by n signal base stations at the current location.
[0092] In the embodiment of the present application, the signal detection device detects the signal strengths transmitted by n signal base stations that can be detected at the current location, and obtains actual signal parameters of the wireless signals transmitted by the n signal base stations.
[0093] Step 205: Based on the actual signal parameters corresponding to the n signal base stations, the n signal base stations, the current location and the m points to be analyzed, determine the target signal parameters of each point to be analyzed corresponding to each signal base station.
[0094] In an embodiment of the present application, the signal detection device calculates the theoretical signal parameters of each signal base station at the current position and at m points to be analyzed, and then analyzes the actual signal parameters corresponding to the n signal base stations, the theoretical signal parameters at the current position and at m points to be analyzed, to obtain the target signal parameters of each point to be analyzed corresponding to each signal base station.
[0095] Step 206: Output the target signal parameters of each to-be-analyzed point corresponding to each signal base station.
[0096] In an embodiment of the present application, the signal detection device has a display screen. At this time, the signal detection device can display and output the target signal parameters calculated by each signal base station corresponding to each point to be analyzed, thereby realizing the display of the target signal parameters of each point to be analyzed corresponding to each signal base station.
[0097] Based on the above embodiments, in other embodiments of the present application, step 201 can be implemented by steps 201a to 201c:
[0098] Step 201a: determine the edge of the current space and obtain edge information of the current space.
[0099] In an embodiment of the present application, the edge of the current space can be determined by being close to closed space obstructions such as walls. In some application scenarios, the edge of the current space can also be a certain range in an open space, which does not necessarily require obstructions such as walls.
[0100] Exemplarily, the signal detection device can determine the spatial range of the classroom, obtain the positions of the walls around the classroom, and obtain the edge information of the classroom.
[0101] Step 201b: Determine at least one reference height position in the current space.
[0102] In an embodiment of the present application, at least one reference height position may be a predetermined empirical value, or may be determined based on the spatial height in the current space, and the number of reference height positions may be determined based on actual conditions.
[0103] Step 201c: determine m points to be analyzed on the trajectory where a horizontal plane corresponding to at least one reference height position in the current space intersects with the edge information.
[0104] Wherein, m is an integer greater than or equal to 1, and the signal detection device does not need to be installed with a user identification card, and is used to support frequency scanning of full-band wireless communication signals provided by at least one operator.
[0105] In the embodiment of the present application, a horizontal plane with each reference height position as the height in the current space is determined, and a trajectory of the horizontal plane intersecting with the edge information of the current space is obtained, and the corresponding points to be analyzed are determined on the trajectory, thereby obtaining m points to be analyzed. When determining the points to be analyzed on the trajectory where the horizontal plane corresponding to each reference height position intersects with the edge information of the current space, the points to be analyzed can be determined according to a preset interval length or a preset interval arc length. The coordinate positions of the points to be analyzed determined on the trajectory where the horizontal planes corresponding to different reference height positions intersect with the edge information of the current space can be the same or different, which can be determined by the actual situation and is not specifically limited here.
[0106] Based on the above embodiment, in other embodiments of the present application, step 201b can be implemented by steps a11 to a12:
[0107] Step a11, determine the current height position of the current position in the current space.
[0108] In the embodiment of the present application, the current height position of the current position refers to the indoor height position of the current position in the current space, that is, the distance between the current position and the ground of the space in which the current position is located. For example, when the signal detection device is placed on a student desk in a classroom, the corresponding current height position is recorded as the desk height of the student desk.
[0109] Step a12: Taking the current height position as a reference and according to a preset height difference, determine at least one reference height position in a direction perpendicular to the ground in the current space.
[0110] Wherein, at least one reference altitude position includes at least the current altitude position.
[0111] In the embodiment of the present application, the preset height difference is an empirical value determined according to the actual situation, and can be corrected and adjusted according to the actual situation. The signal detection device uses the current height position as a reference, and according to the preset height difference, determines at least one reference height position upward and downward in the height direction according to the preset height difference. Exemplarily, taking the current height position of the desktop height, that is, the height position from the classroom floor as 1 meter (m), and the preset height difference of 0.2m as an example, the 0.8m height position, 1m height position, and 1.2m height position can be determined as reference height positions in the height direction.
[0112] Based on the above embodiments, in other embodiments of the present application, step 204 can be implemented by steps 204a to 204b:
[0113] Step 204a: adopting a target acquisition method, a signal detection device performs a preset number of signal acquisitions on n wireless signals at the current location to obtain a reference signal parameter set of the n wireless signals.
[0114] In an embodiment of the present application, the preset number of times can be an empirical value obtained based on experience, and usually the value is at least 3, that is, the signal detection device uses a polling method to collect signals of n wireless signals at the current location at least 3 times to obtain a reference signal parameter set of the n wireless signals.
[0115] Exemplarily, assuming there are three signal base stations A1, A2 and A3, the corresponding reference signal parameter sets of the three wireless signals can be recorded as ((a11, a12, a13), (a21, a22, a23), (a31, a32, a33)), where the signal strengths of the wireless signals detected when the three signal base stations A1, A2 and A3 are polled for the first time are a11, a21 and a31, the signal strengths of the wireless signals detected when the three signal base stations A1, A2 and A3 are polled for the second time are a12, a22 and a32, and the signal strengths of the wireless signals detected when the three signal base stations A1, A2 and A3 are polled for the third time are a13, a23 and a33.
[0116] Step 204b: Compare and analyze the signal values in the reference signal parameter set of each wireless signal, and use the signal value that meets the target requirement as the actual signal parameter of each wireless signal.
[0117] In the embodiment of the present application, a11, a12 and a13 are compared and analyzed to determine the signal value that meets the target requirements as the actual signal parameter of the wireless signal A1. In some application scenarios, the target requirement may be the maximum signal value, that is, the strongest signal strength.
[0118] Based on the above embodiments, in other embodiments of the present application, step 205 can be implemented by steps 205a to 205b:
[0119] Step 205a: Based on n signal base stations, m points to be analyzed and the current location, m first reference signal parameters corresponding to each signal base station and second reference signal parameters corresponding to each signal base station are calculated.
[0120] Each point to be analyzed corresponds to a first reference signal parameter, and the second reference signal parameter corresponds to the current position.
[0121] In the embodiment of the present application, the signal detection device determines the theoretical signal parameters of each signal base station at the m points to be analyzed and the current position in the current space according to the positional relationship between n signal base stations, m points to be analyzed and the current position, and according to the distribution law of signal strength, and obtains the m first reference signal parameters corresponding to each signal base station and the second reference signal parameters corresponding to each signal base station. In other words, the signal detection device performs signal calculation on the positional relationship between n signal base stations, m points to be analyzed and the current position based on a preset signal calculation model, and determines the theoretical signal parameters corresponding to each point to be analyzed under each signal base station, obtains the m first reference signal parameters corresponding to each signal base station, and the theoretical signal parameters corresponding to the current position under each signal base station, and obtains the second reference signal parameters corresponding to each signal base station.
[0122] Step 205b: determine the target signal parameter of each to-be-analyzed point corresponding to each signal base station based on the actual signal parameters corresponding to the n signal base stations, the second reference signal parameters corresponding to the n signal base stations, and the m first reference signal parameters corresponding to each signal base station.
[0123] In the embodiment of the present application, the actual signal parameters of the n signal base stations at the current location and the second parameter signal parameters corresponding to the n signal base stations at the current location are analyzed to obtain the analysis results, and then the analysis results are used to correct the m first parameter signal parameters corresponding to each signal base station to obtain the target signal parameters of each signal base station at each point to be analyzed. In other words, the signal detection device calculates the error between the actual signal parameter corresponding to each signal base station and the second reference signal parameter corresponding to the corresponding signal base station to obtain the corresponding error value, and then corrects the error of each first reference signal parameter corresponding to each signal base station according to the error value corresponding to each signal base station to obtain the target signal parameter of each point to be analyzed corresponding to each signal base station.
[0124] Based on the above embodiment, in other embodiments of the present application, step 205a can be implemented by steps b11 to b15:
[0125] Step b11: determine the spatial distance between each signal base station and each point to be analyzed, and obtain the first spatial distance corresponding to the m points to be analyzed under n signal base stations.
[0126] In the embodiment of the present application, the spatial distance between each signal base station and each point to be analyzed is calculated according to a preset spatial distance calculation model to obtain a first spatial distance between each signal base station and each point to be analyzed.
[0127] Step b12: determine the spatial distance between each signal base station and the current location, and obtain the second spatial distance corresponding to the current location under n signal base stations.
[0128] In the embodiment of the present application, the spatial distance between each signal base station and each current location is calculated according to a preset spatial distance calculation model to obtain a second spatial distance between each signal base station and the current location.
[0129] Step b13, determine the first position height of the current space.
[0130] The first position height is the height of the current space relative to the ground.
[0131] In an embodiment of the present application, the signal detection device determines that the first position height of the current space is the height of the current space in the current building; in some cases, it can also be approximated by the height positioning device set in the floor signal detection device, that is, the first position height is the height distance between the current position and the ground.
[0132] Step b14: Determine a target path loss calculation model based on the first position height.
[0133] In the embodiment of the present application, due to different spatial heights and different signal blocking obstacles, resulting in different signal losses, different path loss calculation models can be determined according to the current first position height of the signal detection device relative to the earth's ground.
[0134] For example, when the first position height indicates that the current space belongs to a high floor, it is a straight-line propagation without obstruction in the middle of the propagation process, which can be called line-of-sight (LOS) propagation. Therefore, the path loss calculation model mainly includes LOS propagation loss, large-scale space loss and penetration loss. When the first position height indicates that the current space is located on a low floor, it will be affected by obstacles in the actual environment. The wireless signal cannot be directly transmitted between the transmitting end and the signal receiving end, that is, the signal detection device. This can be called non-line-of-sight (NLOS) propagation. The path loss calculation model mainly includes NLOS propagation loss, large-scale space loss and penetration loss.
[0135] Step b15, based on n signal base stations, the current position, the first spatial distances corresponding to the m points to be analyzed under the n signal base stations, and the second spatial distances corresponding to the current position under the n signal base stations, the target path calculation model is used to calculate the m first reference signal parameters corresponding to each signal base station and the second reference signal parameters corresponding to each signal base station.
[0136] In an embodiment of the present application, the target path calculation model calculates the relevant parameters of each signal base station, the relevant parameters at the current position, and the first spatial distance corresponding to each point to be analyzed under the corresponding signal base station, and m first reference signal parameters corresponding to each signal base station can be obtained; the target path calculation model calculates the relevant parameters of each signal base station, the relevant parameters at the current position, and the first spatial distance corresponding to the current position under the corresponding signal base station, and m first reference signal parameters corresponding to each signal base station can be obtained.
[0137] Based on the above embodiment, in other embodiments of the present application, step b15 can be implemented by steps b151 to b154:
[0138] Step b151, determine the operating frequency of each signal base station and the effective height of each signal base station.
[0139] In the embodiment of the present application, the signal detection device can obtain the operating frequency of each signal base station and the effective height of each signal base station by communicating with each signal base station. The effective height of each signal base station is the height between the signal transmitting antenna of each signal base station and the ground.
[0140] Step b152, determine the second position height of the current position.
[0141] The second position height is the height of the current position relative to the ground.
[0142] In the embodiment of the present application, the signal detection device determines the distance between the current position and the ground of the earth to obtain the second position height. In some cases, such as when the current space is high, the second position height can be approximately equal to the first position height.
[0143] Step b153, input the operating frequency of each signal base station, the effective height of the corresponding signal base station, each first spatial distance and second position height corresponding to the corresponding signal base station into the target path calculation model for calculation to obtain m first reference signal parameters corresponding to each signal base station.
[0144] Step b154, input the operating frequency of each signal base station, the effective height of the corresponding signal base station, each second spatial distance and second position height corresponding to the corresponding signal base station into the target path calculation model for calculation to obtain the second reference signal parameters corresponding to each signal base station.
[0145] Based on the above embodiment, in other embodiments of the present application, step 205b can be implemented by steps c11 to c19:
[0146] Step c11, determining the target angle between the line connecting the current position and each point to be analyzed and the horizontal plane.
[0147] In the embodiment of the present application, after connecting the current position with each point to be analyzed, the angle between the connecting line and a horizontal plane parallel to the ground is determined to obtain the target angle.
[0148] Step c12: From the m points to be analyzed, determine the point whose target angle is smaller than the preset angle as the first analysis point.
[0149] In the embodiment of the present application, the preset angle is an empirical angle value obtained from a large number of experiments, for example, the value may be 45 degrees. In this way, the m points to be analyzed are grouped according to their target angles, and the points to be analyzed whose target angles are less than the preset angle are determined as the first analysis points.
[0150] Step c13: From the m points to be analyzed, determine the point whose target angle is greater than or equal to the preset angle as the second analysis point.
[0151] In the embodiment of the present application, among the m points to be analyzed, the point to be analyzed whose target angle is greater than or equal to the preset angle is determined as the second analysis point.
[0152] Step c14: Calculate the error between the actual signal parameter of each signal base station and the second reference signal parameter of the corresponding signal base station to obtain the target error corresponding to each signal base station.
[0153] In an embodiment of the present application, the target error Δi corresponding to each signal base station is Δi=ai-bi; wherein, i=1, 2, ..., n, ai is the actual signal parameter of the i-th signal base station, and bi is the second reference signal parameter of the i-th signal base station.
[0154] Step c15: Calculate the sum of each first reference signal parameter corresponding to each signal base station and the target error corresponding to each signal base station to obtain the target value of each to-be-analyzed point corresponding to each signal base station.
[0155] In an embodiment of the present application, the target value cij=dij+Δi of each point to be analyzed corresponding to each signal base station, wherein j=1,2,...,m, and dij is the first reference signal parameter of the jth point to be analyzed corresponding to the i-th signal base station.
[0156] Step c16: Obtain the third spatial distance between each first analysis point and the current position.
[0157] In an embodiment of the present application, the signal detection device can use a distance measuring device to detect the distance between the current position of each point to be analyzed, so that the third spatial distance between each first analysis point and the current position can be obtained. In some application scenarios, the signal detection device can also use the distance measuring device to measure the third spatial distance between the first analysis point obtained in the group and the current position.
[0158] Step c17, calculating the target product between the third spatial distance of each first analysis point and the preset coefficient.
[0159] In the embodiment of the present application, the preset coefficient is an empirical value obtained from a large number of experiments, and its value is in the range of 0 to 1, for example, the value may be 0.5. The target product is recorded as the signal loss caused by the wireless signal propagating indoors.
[0160] Step c18, calculating the difference between the target value and the target product of the first analysis point corresponding to each signal base station, and obtaining the target signal parameter of each first analysis point corresponding to each signal base station.
[0161] Step c19: Determine the target signal parameter of the second analysis point corresponding to each signal base station as the target value of the second analysis point corresponding to each signal base station.
[0162] Based on the above embodiments, in other embodiments of the present application, refer to Figure 2 As shown, before the signal detection device executes step 201, it may also choose to execute steps 207 to 209:
[0163] Step 207: Obtain the spatial environment information of the current space.
[0164] In an embodiment of the present application, the spatial environment information includes spatial information of the current space and spatial layout information of the current space, which may be input by a user to the signal detection device, or may be collected by the signal detection device through a camera. When the signal detection device and the signal detection device are two independent devices, the spatial environment information may be sent by the information collection device to the signal detection device.
[0165] Step 208: Determine at least one placement position to be recommended based on the spatial environment information.
[0166] The recommended placement position is used to place the signal detection device.
[0167] In an embodiment of the present application, the signal detection device analyzes the spatial environment information to determine, for example, the location of a door and a window, and determines the location of the door and the location of the window as at least one recommended placement location.
[0168] Step 209: output prompt information of at least one recommended placement location.
[0169] In the embodiment of the present application, the signal detection device generates a prompt information for position placement according to the determined at least one recommended placement position, and outputs and displays the prompt information so that the user can place the signal detection device according to the recommended position. It should be noted that in some application scenarios, the user may not place the signal detection device according to the prompt information, that is, in some application scenarios, the current position of the signal detection device may be one of the at least one recommended placement position indicated in the prompt information, or may not be any of the at least one recommended placement position.
[0170] Based on the foregoing embodiments, in other embodiments of the present application, the embodiments of the present application provide a signal detection device, which is used to measure signal distribution in a classroom for detecting an examination. Correspondingly, the signal detection device includes at least the following modules: a communication module, an antenna module, a global positioning system (GPS) positioning module, a direct time of flight (dTOF) sensor module, a data storage module, a microprocessor, an algorithm processing module, and a data return module. Among them, the communication module is used to support multi-link aggregation communication, and can support data analysis of wireless signals such as 2G, 3G, 4G, 5G, Wi-Fi, and Bluetooth. The communication module can be provided with an expansion module for subsequent expansion of the signal detection module for communication signals of other standards; the antenna module has multiple antennas built in, which respectively support the reception of wireless signal data of 2G, 3G, 4G, 5G, WIFI, and Bluetooth. Correspondingly, the antenna module can also include an expansion module for subsequent expansion of antennas supporting communication signals of other standards; the dTOF data The digital sensor module includes a transmitter, a receiver and a time-to-digital converter, which is used to transmit and receive N light signals within a single frame measurement time, and then make statistics on the recorded N flight times to use the flight time that occurs most frequently to calculate the target distance; the data storage module is used to store the collected wireless signal data and the calculated target distance and other data; the algorithm processing module is used to determine the signal strength distribution inside the examination room based on intelligent analysis such as the target distance obtained by the dTOF digital sensor module, the wireless signal data of various standards obtained by the communication module, and the wireless signal attenuation model.
[0171] In some application scenarios, the signal detection device can be managed and controlled by a control application on a third-party device such as a mobile device. For example, the control application can be used to control the examination room signal detection device to perform data collection, examination room marking, distance measurement and other actions. Furthermore, in some application scenarios, for example, when the amount of data collected by the signal detection device is large, the signal detection device can also have a communication connection with the data processing platform, so that the signal detection device can also compress the collected data and transmit it back to the data processing platform, so that the data processing platform can analyze and process the data to determine the distribution of the signal in the examination room.
[0172] Based on the aforementioned signal detection device, the embodiment of the present application provides a signal detection method, and the implementation steps can refer to the following steps:
[0173] Step d11: determine the current location of the signal detection device.
[0174] Among them, the user can place the signal detection device on a desk in the middle position near the window or door of the examination room classroom, or on a bracket of the corresponding height in the same position. In some application scenarios, the signal detection device can obtain the spatial environment information of the examination room classroom, determine the position of the windows and doors in the examination room classroom, and obtain the signal strength at the position of the windows and doors, and then select the position with a stronger signal as the recommended position for placing the signal detection device, and generate recommendation information to recommend the user to place the signal acquisition device at the recommended position. The placement position selected by the final user, that is, the current position, can be recorded as A.
[0175] For example, Figure 3 As shown, the examination room can be regarded as a rectangular space with a length of L, a width of D and a height of H, and a three-dimensional space coordinate system of XYZ is established. Correspondingly, it is assumed that the height of the current placement A is 1m, which is generally determined by the height of the desk where the signal detection device is placed.
[0176] Step d12: determine the distance from the current position to the feature point.
[0177] Among them, step d12 can be implemented by step d121 and step d122:
[0178] Step d121, determine the feature points.
[0179] Among them, taking the height of 1m of the current position A as a reference, with a height change interval of 0.2 meters, a height of 0.8m is determined downward and a height of 1.2m is determined upward, and three height layers are obtained. Taking these three height layers as a reference, three rectangular planes parallel to the horizontal plane are determined. For each rectangular plane determined, its feature points may include the points T1, T2, T3, and T4 where the four corners of the rectangle are located, as well as n points on the length and width of the rectangle. The size of n can be obtained according to the length L and width D of the examination room classroom. For example, with a granularity of 0.5m, n = (L + D) * 2 / 0.5. In this way, for one examination room, the number of feature points that need to be collected is N = n * 3. It should be noted that the feature points correspond to the aforementioned points to be analyzed.
[0180] Step d122, determine the distance from the current position to the feature point.
[0181] Among them, the signal detection device is controlled to measure the distance between the current position and each characteristic point, and the obtained distance can be recorded as d1, d2, d3, ..., dN. Among them, the distance measurement control of the signal detection device can be realized by a mobile phone that has a communication connection with the signal detection device, or it can be realized by a physical control button or a virtual button set on the signal detection device, which can be determined according to the actual situation. The dTOF digital sensor module in the signal detection device can be realized by a single photon avalanche diode (SPAD) with the characteristic of detecting single photon sensitivity. In this way, the time-correlated single photon technology method is adopted to measure the distance between the emission point and the reflection point by the time difference between pulse emission and reception, that is, N times of light signal is emitted and received within a single frame measurement time, and then the recorded N flight times are counted, and the flight time that appears most frequently is used to calculate the distance, or the average flight time for the same reflection point is calculated to calculate the distance. Among them, the distance measurement formula is d=c*Δt / 2, where Δt is the measured flight time and c refers to the speed of light. As Figure 4 As shown, the figure only shows the relationship between the specific points T1, T2, T3, T4 on the 1m altitude layer and the current collection position A and the measured and collected distances.
[0182] Step d13: Collect the wireless network signal strength at the current location.
[0183] Among them, the signal detection device obtains the wireless network signal strength of the examination room through the antenna module and the communication module. The specific process is as follows: first, the antenna module and the communication module are initialized, the full-band wireless network signal is received through the antenna module, and then the full-band wireless network signal is analyzed through the communication module; then, the signal detection device does not need any operator's SIM card, and adopts a polling query method. Within a certain period of time, such as 2 minutes, all cells in the full-band of each wireless network signal operator are scanned in a frequency-locked manner to obtain wireless network signal parameters of all cells in the full-band, and each wireless network signal parameter includes at least the following parameters: Physical Cell Identifier (PCI), Mobile Country Code (MCC), Mobile Network Code (MNC), cell frequency, signal strength such as received signal code power (RSCP) and reference signal receiving power (RSRP), signal quality, signal to interference plus noise ratio (SINR), etc.; finally, the wireless network data collected through multiple rounds of data within 2 minutes is stored in the data storage module. It should be noted that due to the fluctuating nature of wireless network data, a certain time period must be sufficient to collect at least three rounds of full-band wireless network signal data.
[0184] Step d14: Calculate the signal strength of each wireless network signal at the characteristic point.
[0185] Among them, step d14 can be implemented by steps d141 and d142:
[0186] Step d141, calculating the initial signal strength of each wireless network signal at the characteristic point.
[0187] Among them, the theoretical value of the signal strength of the feature point can be calculated using the path loss model based on the position of the feature point determined in the above step d121, as well as the longitude and latitude, altitude, transmission power and other information of the nearby base stations.
[0188] For example, it is assumed that the distribution diagram of the base station and the current location in the examination room is as follows: Figure 5 As shown, when calculating the signal strength of the base station at the characteristic point Tn, first use the formula Determine the spatial distance d between the base station and the feature point Tn 3D In some cases, the spatial distance d between the base station and the feature point Tn is 3Dis the sum of the spatial distance between the base station and the current position and the spatial distance between the current position and the feature point Tn. In the above formula, d 2D-out is the plane distance to the outdoor part, d 2D-in is the plane distance to the indoor part, h BS is the base station antenna height, h UT is the antenna height of the signal detection device from the outdoor ground. For LOS scenarios, h UT When the height is greater than or equal to the preset height, the signal propagation loss P LOS It can be calculated by the following calculation model: PL LOS =28+40lg(d 3D )+20lgf c -9lg((d' BP ) 2 +(h BS -h UT ) 2 ), where f c is the operating frequency of the base station, d BP The breakpoint distance set for the model. For NLOS scenarios, h UT When the height is less than the preset value, the signal propagation loss P NLOS It can be calculated by the following calculation model: PL NLOS =13.54+39.08lg(d 3D )+20lgf c -0.6(h UT -1.65). It should be noted that in the calculation model of signal propagation loss PLOS and signal propagation loss PNLOS, each weight coefficient is an empirical value and can be adjusted according to actual conditions. Here is an example. Based on the above calculation formula, it can be determined that the calculation model of the initial signal strength at the feature point can be recorded as: or Where PL TW is the loss caused by the wireless network signal passing through the outer wall of the building. In the embodiment of the present application, PL TW The value can be 20dB, PL in is the additional loss caused by the indoor propagation of wireless signals. In the embodiment of the present application, PL in The value can be 0.5d 2D-in , σ P 2 is the standard deviation of the penetration loss. In the embodiment of the present application, σ P 2 The value can be 0dB.
[0189] Step d142: Calculate the final signal strength of each wireless network signal at the characteristic point.
[0190] The wireless network signal strength at the current location collected through multiple rounds in step d13 is analyzed, and the strongest signal strength of each frequency band and each cell is selected as the reference signal strength S corresponding to each signal base station in the classroom. 0 .
[0191] Based on the initial signal strength S at the current location calculated in step d141 0 ' and the reference signal strength S at the current location 0 , through the formula Δ=S 0 -S 0 'Calculate and obtain the deviation correction variable value Δ corresponding to each signal base station, and the deviation correction variable value corresponds to the aforementioned target error.
[0192] by Figure 5 Taking the feature point Tn shown as an example, determine the angle α between the line connecting the base station transmitter and the feature point Tn receiver and the horizontal line; if α is greater than or equal to the preset angle, the final signal strength at the feature point Tn can be calculated by the following formula: Sn=PLn+Δ, where PLn is the initial signal strength of the feature point Tn; if α is less than the preset angle, the final signal strength at the feature point Tn can be calculated by the following formula: Sn=PLn+Δ-dn, where dn is the distance from the feature point Tn to the current position.
[0193] Step d15: output the wireless signal strength distribution of N feature points.
[0194] In other embodiments of the present application, steps d11 to d15 can be obtained by analyzing the data processing platform.
[0195] In this way, the signal strength data of different locations inside the examination room can be quickly and comprehensively obtained, which can improve the efficiency and accuracy of the early signal survey of the examination room, support the selection and deployment of jammers in the examination room, and realize the shielding and signal management of the examination room signal.
[0196] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.
[0197] The signal detection method provided in the embodiment of the present application determines, through a signal detection device, m points to be analyzed in the space where the signal detection device is currently located, determines the current position of the signal detection device in the current space, and determines n signal base stations corresponding to the signals covered in the current space, then obtains the actual signal parameters of the wireless signals transmitted by the n signal base stations at the current position, and then determines the target signal parameters of each point to be analyzed corresponding to each signal base station based on the actual signal parameters corresponding to the n signal base stations, the n signal base stations, the current position and the m points to be analyzed, and finally outputs the target signal parameters of each point to be analyzed corresponding to each signal base station. In this way, by simultaneously detecting and analyzing the signals of n signal base stations near the current space in the current space, the target signal parameters at the m points to be analyzed in the current space of the signal detection device can be quickly determined, so that the signal distribution in the current space can be determined, which solves the current problem of low efficiency in wireless communication signal detection in special occasions, and proposes a method for wireless communication signal detection in special occasions, which effectively simplifies the process of wireless communication signal detection in special occasions, shortens the time consumed by wireless communication signal detection in special occasions, and improves the detection efficiency of wireless communication signals in special occasions.
