[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. 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.

[0035] The terms "first", "second", etc. in this specification and claims are used to distinguish similar objects, and are not used to describe a particular order or precedence. It should be understood that the terms used in this way can be interchanged where appropriate so that the embodiments of the present application are implemented in a sequence other than those illustrated or described herein. In addition, "and / or" in this specification and claims means at least one of the connected objects, and the character " / " generally means that the objects associated with each other are in an "or" relationship.

[0036] Among the wireless network information measured by the signal detection device, the wireless signal strength is particularly important, which reflects the coverage of the wireless network and is the basis for wireless network quality assurance. Figure 1 , is a schematic diagram of a signal detection device provided by an embodiment of the present application. Figure 1As shown, the function of the signal detection device is to detect information such as the wireless signal strength in the environment and report the detected information to the monitoring platform. The monitoring platform can remotely grasp the wireless network information in the environment where the signal detection device is located, thereby monitoring changes in network quality. When the quality deteriorates, the monitoring platform can promptly trigger an alarm and notify maintenance personnel to go for repairs, thereby improving network user satisfaction.

[0037] See also Figure 2 , is a schematic diagram of the structure of a signal detection device provided by an embodiment of the present application. Figure 2 As shown, the internal modules of the signal detection device include an antenna module, a detection module, a circuit module and a power supply module, wherein the antenna module is responsible for sending and receiving wireless signals, the detection module is responsible for detecting wireless signals, and the power supply module provides power for the circuit module and the detection module.

[0038] Usually, the wired transmission method is used to test the device's ability to detect wireless signal strength. Figure 3 , is a scene diagram of a wired conduction measurement provided by an embodiment of the present application. Figure 3 As shown, the signal source replaces the antenna module of the signal detection device, and the signal is transmitted from the signal source to the signal detection device through a wired manner.

[0039] However, wired conduction can only test the performance of some modules in the signal detection device, and fails to take into account the influence of the antenna module, the housing of the device, etc. on the signal strength. For example, since general antennas are directional, when the device is installed facing the signal transmission direction and when it is installed facing away from the signal transmission direction, the signal strength detected by the device is very different; since general antennas have working bandwidth, the accuracy of the device detecting a certain frequency point does not mean the accuracy of detecting another frequency point; the device housing is generally made of plastic, which has loss to electromagnetic waves, etc. Therefore, wired conduction cannot reflect the actual level of the entire device in the use environment, thereby affecting the accuracy of the device performance test. In fact, wired conduction only measures the performance of the circuit module and the detection module in the device. In actual applications, the installed signal detection device is not just a few modules in the device, but a whole, including the device housing, etc. Therefore, in order to truly simulate the situation in actual applications, the device should be tested as a whole. In view of this, the embodiment of the present application provides a performance test method and system for a signal detection device, which is used to improve the accuracy of the device performance test.

[0040] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0041] The performance testing method of the signal detection device provided in the embodiment of the present application is applicable to various signal detection devices that need to perform performance testing, especially the performance testing of signal strength. By controlling the first antenna to transmit the first wireless signal at multiple frequency points, for each frequency point, the signal detection device performs signal processing at multiple angles to obtain signal processing information at multiple angles. For each angle, based on the signal processing information of the angle and the path loss from the first antenna to the signal detection device at the frequency point, the first indicator value of the performance indicator at the angle is determined, and then based on the first indicator values ​​of the performance indicator at the multiple angles, the second indicator value of the performance indicator at the frequency point is determined, and then based on the second indicator values ​​of the performance indicator at the multiple frequency points, the third indicator value of the performance indicator is obtained. The accuracy of the performance test can be improved, and the performance indicator data reflecting the overall true level of the signal detection device can be used to comprehensively evaluate the performance of the device in the actual use environment. Based on the signal processing information at different angles at different frequencies, a true reflection of the overall performance of the signal detection device is obtained, and the influence of the antenna module and the device housing on the signal is fully considered, so that the test results will more accurately reflect the performance of the device under actual use conditions, thereby improving the accuracy and reliability of wireless network quality assurance.

[0042] Specifically, see Figure 4 , is a flow chart of a performance testing method for a signal detection device provided by an embodiment of the present application. Figure 4 As shown, an embodiment of the present application provides a performance testing method for a signal detection device, which may include the following steps:

[0043] S402, controlling the first antenna to transmit the first wireless signal at multiple frequencies respectively, and for each frequency, controlling the signal detection device to perform signal processing on the first wireless signal at multiple angles to obtain signal processing information at multiple angles.

[0044] Among them, the first antenna is an antenna at the signal source end that has the function of transmitting and receiving wireless signals. In the embodiment of the present application, the first antenna is mainly used to transmit the wireless signal required for the test. The wireless signal is a signal propagated by radio electromagnetic waves. The first wireless signal is a wireless signal required for the performance test of the signal detection device. The frequency point refers to the frequency point of the wireless signal, that is, the specific value or range of the signal frequency.

[0045] The signal detection device is a device that has the function of detecting information such as wireless signal strength in the environment. In some embodiments, the signal detection device can report the detected wireless signal strength and other information to a cloud platform, such as a monitoring platform, a management platform, an operation and maintenance platform, etc.

[0046] In an embodiment of the present application, for each frequency point and each angle, the first antenna is controlled to transmit a first wireless signal at the frequency point, and the signal detection device is controlled to detect the first wireless signal at the angle and perform signal processing on the detected signal to obtain signal processing information of the angle, and by changing the angle of the signal detection device, signal processing information at different angles at the frequency point is obtained.

[0047] The angle refers to the angle generated when the signal detection device is installed or placed in a certain way and rotated left or right or up and down by controlling the signal detection device. It is usually related to the position of the signal source, that is, the first antenna relative to the signal detection device. When the angle of the signal detection device changes, the angle of the antenna module in the device pointing to the first antenna will change. For example: Figure 5A In the test scenario shown, the signal detection device is placed on a turntable. By controlling the signal detection device to rotate left and right, the angle of the signal detection device changes, that is, the angle at which the antenna module in the control device points to the first antenna changes.

[0048] As an example, the angle setting of the signal detection device can be set according to a preset angle step. For example, assuming that the preset angle step is 60, Figure 5A In the test scenario shown, with the first antenna as a reference, the direction of the signal detection device toward the first antenna is determined to be 0°. After the angle 0° test is completed, the signal detection device is controlled to rotate 60° to the right to continue the test. After the test is completed, it is rotated 60° to the right to continue the test until the signal detection device rotates 360° to the desired angle.

[0049] In order to accurately measure the performance indicators of the device at different angles, the angle step can be reduced, thereby achieving refined testing of the performance of the signal detection device.

[0050] In the actual test process, the frequency point can be determined first, and the signal processing information of each angle can be obtained by changing the angle of the signal detection device, and then the next frequency point can be changed to continue the test. It is also possible to determine the angle first, and obtain the signal processing information of the angle at different frequencies by changing the frequency point, and then change the angle to continue the test. The embodiments of the present application do not specifically limit this.

[0051] Among them, the signal processing information is the relevant data obtained after signal processing of the wireless signal detected by the signal detection device. The signal processing information at each angle includes but is not limited to: the second received signal strength of the signal detection device at this angle, the transmitted signal strength corresponding to the minimum detection signal strength of the signal detection device at this angle, and the transmitted signal strength corresponding to the minimum reported signal strength of the signal detection device at this angle. The minimum detection signal strength is the minimum signal strength detected by the signal detection device at each angle. The minimum reported signal strength is the minimum signal strength of each angle reported by the signal detection device to the cloud platform. The transmitted signal strength is the signal strength of the first wireless signal transmitted by the first antenna. The second received signal strength is the signal strength of the second wireless signal received by the signal detection device.

[0052] In order to improve the accuracy of the performance test, when testing the second received signal strength of the signal detection device at each angle, including the second received signal strength at the same angle at different frequencies, the signal strength of the first wireless signal transmitted by the first antenna, i.e., the transmitted signal strength, is controlled within the same range or specific value. And this range or specific value must meet certain conditions to ensure that the signal detection device can detect the corresponding signal information at different frequencies and angles.

[0053] When testing the transmitted signal strength corresponding to the minimum detection signal strength of the signal detection device at each angle, and the transmitted signal strength corresponding to the minimum reported signal strength of the signal detection device at each angle, it is necessary to test the signal strength of the first wireless signal transmitted by the first antenna by changing the signal strength at different frequencies and angles.

[0054] As an optional implementation, the above S402 may include the following steps: for each frequency point and each angle, controlling the first antenna to transmit the first wireless signal at the frequency point, and controlling the signal detection device to perform signal detection on the first wireless signal at the angle;

[0055] If the signal detection device detects the first wireless signal, the transmission signal strength of the first wireless signal is reduced, and the first antenna is controlled to transmit the first wireless signal at the frequency, and the signal detection device is controlled to detect the first wireless signal at the angle repeatedly until the signal detection device cannot detect the first wireless signal;

[0056] When the signal detection device cannot detect the first wireless signal, the transmission signal strength of the first wireless signal is determined as the transmission signal strength corresponding to the minimum detection signal strength at the angle.

[0057] In an embodiment of the present application, for each frequency point and each angle, the first antenna is controlled to transmit the first wireless signal at the frequency point, and the signal detection device is controlled to perform signal detection on the first wireless signal at the angle. At the beginning, the signal strength of the first wireless signal transmitted by the first antenna is controlled to a relatively large value. By continuously reducing the signal strength of the first wireless signal transmitted by the first antenna, the critical value at which the signal detection device can just detect the first wireless signal is found. When the signal detection device can just detect the first wireless signal, the signal strength of the first wireless signal transmitted by the first antenna at this time is used as the transmission signal strength corresponding to the minimum detection signal strength of the signal detection device at the angle.

[0058] During the actual test process, the signal strength of the first wireless signal transmitted by the first antenna may be controlled to a relatively small value at the beginning, and the critical value at which the signal detection device can just detect the first wireless signal may be found by continuously increasing the signal strength of the first wireless signal transmitted by the first antenna. For example: for frequency point B1, the first antenna is controlled to transmit the first wireless signal at B1, and the signal detection device is controlled to detect the first wireless signal at an angle of 0°. At the beginning of the test, the signal strength of the first wireless signal transmitted by the first antenna is controlled to a relatively large value, assuming it is -50dBm. If it is determined that the signal detection device detects the signal information of the first wireless signal, the signal strength of the first wireless signal transmitted by the first antenna is continuously reduced until the signal detection device cannot detect the first wireless signal. Assuming that the signal strength of the first wireless signal transmitted by the first antenna is -79, the signal detection device just cannot detect the first wireless signal, then the transmission signal strength corresponding to the minimum detection signal strength at frequency point B1 and angle 0° is -79; or, at the beginning of the test, the signal strength of the first wireless signal transmitted by the first antenna is controlled to a relatively small value, and the signal strength of the first wireless signal transmitted by the first antenna is continuously increased until the signal detection device can just detect the first wireless signal.

[0059] As an optional manner, the above S402 may include the following steps: for each frequency point and each angle, controlling the first antenna to transmit the first wireless signal at the frequency point, and controlling the signal detection device to perform signal detection on the first wireless signal at the angle;

[0060] If the signal detection device cannot detect the first wireless signal, increase the transmission signal strength of the first wireless signal, and repeatedly control the first antenna to transmit the first wireless signal at the frequency point, and control the signal detection device to perform signal detection on the first wireless signal at the angle until the signal detection device detects the first wireless signal;

[0061] When the signal detection device detects the first wireless signal, the transmission signal strength of the first wireless signal is determined as the transmission signal strength corresponding to the minimum detection signal strength at the angle.

[0062] The embodiment of the present application transmits signals at multiple frequencies and detects signals at multiple angles on the signal detection device to determine the minimum detection signal strength, including gradually reducing the transmission signal strength until the signal detection device cannot detect the signal, thereby determining the minimum detection signal strength at each angle, which can more comprehensively evaluate the detection sensitivity of the device at different frequencies and angles, and ensure the accuracy of the minimum signal strength measurement. By gradually reducing the signal strength and recording the minimum value detected, detailed data on the device's ability to respond to weak signals in actual use can be provided, and refined test measurements can be achieved. It can solve the frequency dependency and angle dependency that may be ignored in traditional methods, enhance the comprehensive understanding of the device's true performance, and ensure the accuracy and reliability of the detection sensitivity evaluation.

[0063] As an optional implementation, the above S402 may include the following steps: for each frequency point and each angle, control the first antenna to transmit the first wireless signal at the frequency point, and control the signal detection device to perform signal detection on the first wireless signal at the angle, and send a data transmission request to the cloud platform based on the detected signal strength, where the data transmission request is used for the signal detection device to request uploading the detected signal strength to the cloud platform;

[0064] If the cloud platform receives the signal strength uploaded by the signal detection device, the transmission signal strength of the first wireless signal is reduced, and the first antenna is controlled to transmit the first wireless signal at a frequency, and the signal detection device is controlled to detect the first wireless signal at an angle, and a data transmission request is sent to the cloud platform based on the detected signal strength, until the cloud platform cannot receive the signal strength uploaded by the signal detection device;

[0065] When the cloud platform cannot receive the signal strength uploaded by the signal detection device, the transmit signal strength of the first wireless signal is determined as the transmit signal strength corresponding to the minimum reported signal strength of the angle.

[0066] In an embodiment of the present application, for each frequency point and each angle, the first antenna is controlled to transmit the first wireless signal at the frequency point, and the signal detection device is controlled to perform signal detection on the first wireless signal at the angle, and the detected signal information, such as signal strength, is sent to the cloud platform. At the beginning, the signal strength of the first wireless signal transmitted by the first antenna is controlled to a relatively large value, and by continuously reducing the signal strength of the first wireless signal transmitted by the first antenna, the critical value at which the signal detection device can just detect the first wireless signal and successfully report it to the cloud platform is found. When the signal detection device can just detect the first wireless signal and successfully report it to the cloud platform, the signal strength of the first wireless signal transmitted by the first antenna at this time is used as the transmission signal strength corresponding to the minimum reported signal strength of the signal detection device at this angle.

[0067] During the actual test process, the signal strength of the first wireless signal transmitted by the first antenna can be controlled to a relatively small value at the beginning. By continuously increasing the signal strength of the first wireless signal transmitted by the first antenna, the critical value at which the signal detection device can just detect the first wireless signal and successfully report it to the cloud platform can be found. For example: for frequency point B1, control the first antenna to transmit the first wireless signal at B1, and control the signal detection device to perform signal detection on the first wireless signal at an angle of 0° and upload the detection information to the cloud platform. At the beginning of the test, control the signal strength of the first wireless signal transmitted by the first antenna to a relatively large value, assuming -50dBm. If it is determined that the cloud platform receives the signal information of the first wireless signal, then continuously reduce the signal strength of the first wireless signal transmitted by the first antenna until the cloud platform cannot receive the first wireless signal. Suppose that when the signal strength of the first wireless signal transmitted by the first antenna is -76, the cloud platform just cannot receive the first wireless signal, then the transmission signal strength corresponding to the minimum reported signal strength at frequency point B1 and angle 0° is -76; or, at the beginning of the test, control the signal strength of the first wireless signal transmitted by the first antenna to a relatively small value, and continuously increase the signal strength of the first wireless signal transmitted by the first antenna until the cloud platform can just receive the information of the first wireless signal.

[0068] As an optional manner, the above S402 may include the following steps: for each frequency point and each angle, controlling the first antenna to transmit the first wireless signal at the frequency point, and controlling the signal detection device to perform signal detection on the first wireless signal at the angle, and sending a data transmission request to the cloud platform based on the detected signal strength, the data transmission request is used for the signal detection device to request uploading the detected signal strength to the cloud platform;

[0069] If the cloud platform cannot receive the signal strength uploaded by the signal detection device, the transmission signal strength of the first wireless signal is increased, and the first antenna is repeatedly controlled to transmit the first wireless signal at a frequency point, and the signal detection device is controlled to detect the first wireless signal at an angle, and a data transmission request is sent to the cloud platform based on the detected signal strength until the cloud platform receives the signal strength uploaded by the signal detection device;

[0070] When the cloud platform receives the signal strength uploaded by the signal detection device, the transmit signal strength of the first wireless signal is determined as the transmit signal strength corresponding to the minimum reported signal strength of the angle.

[0071] The embodiment of the present application determines the minimum reported signal strength received by the cloud platform by transmitting signals at multiple frequency points, and detecting signals at multiple angles on the signal detection device and uploading them to the cloud platform, including gradually reducing the signal strength detected by the signal detection device at different frequency points and angles until the cloud platform can no longer receive the signal, thereby determining the minimum reported signal strength, ensuring that not only the device can detect the signal, but also can effectively upload the detection result to the cloud platform, reflecting the data transmission and reporting capabilities of the device in a real environment, realizing refined performance testing, and being able to achieve accurate measurement of the device reporting performance, overcoming the problem of cloud platform communication capabilities that may be overlooked in traditional testing methods, so that the test not only examines the detection capability of the device, but also considers the reliability of data transmission, thereby improving the comprehensiveness and accuracy of the overall performance evaluation, and ensuring the stability and performance of the device in actual applications.

[0072] As an optional manner, the second indicator value of the performance indicator at each frequency point may be obtained in the following manner: for each angle, based on the signal processing information of the angle, determining the first indicator value of the performance indicator of the signal detection device at the angle.

[0073] Based on the first indicator values ​​of the performance indicator at multiple angles, a second indicator value of the performance indicator at the frequency point is determined.

[0074] In order to further improve the accuracy of performance testing, the embodiment of the present application also takes into account the impact of the loss of signal strength caused by the process from the signal source to the signal detection device during the propagation of the wireless signal on the performance test. In the embodiment of the present application, for each frequency point, based on the path loss from the first antenna to the signal detection device and the signal processing information at different angles at the frequency point, the specific values ​​of the performance indicators at different angles and the specific values ​​of the performance indicators at the frequency point are determined, thereby improving the accuracy and reliability of the performance test.

[0075] As an optional method, the above-mentioned determination of the first indicator value of the performance indicator of the signal detection device at each angle based on the signal processing information of the angle may include the following steps: determining the first indicator value of the performance indicator at the angle based on the signal processing information of the angle and the path loss from the first antenna to the signal detection device at the frequency point.

[0076] The embodiment of the present application determines the first indicator value of the performance indicator at each angle by introducing the path loss from the first antenna to the signal detection device at each frequency point, so that the performance evaluation not only considers the influence of the angle and frequency point, but also incorporates the path loss into the calculation. It can solve the problem that the traditional method fails to fully consider the signal propagation loss, improves the authenticity and accuracy of the test results, can provide a more accurate device performance evaluation, further optimizes the performance test of the device in the actual use environment, and enhances the reflection of the test results on the actual performance of the device.

[0077] S404: For each angle, based on the signal processing information of the angle and the path loss from the first antenna to the signal detection device at the frequency point, determine a first indicator value of the performance indicator of the signal detection device at the angle.

[0078] Among them, the performance index is an index used to evaluate the performance of the signal detection device. In an embodiment of the present application, the performance index includes but is not limited to: detection error, detection sensitivity, reporting sensitivity, etc. The detection error refers to the absolute value of the difference between the transmission intensity of the signal at the signal source end and the reception intensity of the signal at the receiving end. For example: assuming that the signal strength emitted by the signal source is A, and the signal strength detected by the device is B, then the device detection error is the absolute value of the difference between A and B. The detection sensitivity is the minimum signal strength value that the signal detection device can detect. The reporting sensitivity is the minimum signal strength value that the signal detection device can detect and report to the cloud platform.

[0079] The index value is a specific value or range of a performance index, etc. The first index value is a specific value of a performance index corresponding to each angle.

[0080] The path loss is the signal strength loss generated in the process of the wireless signal transmitted by the first antenna from the first antenna to the signal detection device.

[0081] As an optional implementation manner, for each frequency point, the path loss from the first antenna to the signal detection device at the frequency point can be measured and obtained in the following manner: controlling the first antenna to transmit the second wireless signal at the frequency point;

[0082] Control the second antenna to receive the second wireless signal, and obtain a first received signal strength of the signal detection device at the frequency point;

[0083] Based on the difference between the transmit signal strength of the second wireless signal and the first receive signal strength at the frequency point, the path loss from the first antenna to the signal detection device at the frequency point is obtained.

[0084] The second antenna is an antenna having the function of transmitting and receiving wireless signals. In the embodiment of the present application, the second antenna is mainly used to receive a second wireless signal transmitted by the second antenna. The second wireless signal is a wireless signal required for path loss calibration. The first received signal strength is the signal strength of the second wireless signal transmitted by the first antenna when the second antenna receives the signal.

[0085] In an embodiment of the present application, for each frequency point, the first antenna is controlled to transmit the second wireless signal, the second antenna is controlled to receive the second wireless signal, and the signal strength when the second antenna receives the second wireless signal is obtained, that is, the first received signal strength of the signal detection device at the frequency point, and the path loss of the wireless signal from the first antenna to the signal detection device at the frequency point is obtained based on the difference between the transmission signal strength of the second wireless signal transmitted by the first antenna and the first received signal strength. For example: Assuming that for each frequency point, the signal strength of the second wireless signal transmitted by the first antenna is -50dBm, the signal strength of the second wireless signal received by the second antenna at frequency point B1, that is, the first received signal strength is -85.68, and the signal strength of the second wireless signal received by the second antenna at frequency point B2, that is, the first received signal strength is -86.75, then the path loss of the wireless signal from the first antenna to the signal detection device, frequency point B1 corresponds to -50-(-85.68) = 35.68dB, and frequency point B2 corresponds to 36.75.

[0086] In the embodiment of the present application, the path from the second antenna to the first antenna is the same as the path from the signal detection device to the first antenna.

[0087] The above loss measurement method is only one of the methods disclosed in the implementation of this application. Other methods can also be used to calibrate the loss, such as measuring based on distance, frequency, and using a propagation loss model in free space to calculate.

[0088] The embodiment of the present application controls the first antenna to transmit the second wireless signal, and then the second antenna receives and measures the strength of the signal, and then calculates the difference between the strength of the transmitted signal and the strength of the received signal to determine the path loss, which can accurately quantify the loss experienced by the signal from transmission to reception, and further enhance the accuracy of performance indicator evaluation. By directly measuring the path loss and combining it with the angle signal processing information, a more comprehensive and realistic performance testing method is used to solve the problem that the actual path loss cannot be directly obtained in the traditional testing method, so that the test results can more accurately reflect the performance of the device in the actual use environment, and improve the reliability of wireless network quality evaluation.

[0089] As an optional method, when the performance indicator includes detection error and the signal processing information of each angle includes the second received signal strength of the signal detection device at that angle, the detection error of the signal detection device at that angle can be obtained in the following way: based on the difference between the second received signal strength at the angle and the transmitted signal strength of the second wireless signal at the frequency point, the detection error of the signal detection device at the angle is obtained.

[0090] In an embodiment of the present application, for each frequency point and each angle, the first antenna is controlled to transmit a first wireless signal at the frequency point, the first wireless signal is detected at the angle by controlling the signal detection device, and the signal strength when the signal detection device detects the first wireless signal is obtained, that is, the second received signal strength of the signal detection device at the angle, based on the difference between the second received signal strength at the angle and the transmitted signal strength of the first wireless signal transmitted by the first antenna, the specific value of the detection error of the signal detection device at the angle is obtained. For example: assuming that the signal strength of the first wireless signal transmitted by the first antenna at each angle is -50dBm, for frequency point B1, the signal detection device receives the signal strength of the first wireless signal at an angle of 0°, that is, the second received signal strength is -88.75dBm, and receives the signal strength of the first wireless signal at an angle of 60°, that is, the second received signal strength is -86.62dBm, then the specific value of the detection error corresponding to the frequency point B1 angle of 0°, that is, the first index value is: |-50-(-88.75)|=38.75, the specific value of the detection error corresponding to the frequency point B1 angle of 60°, that is, the first index value is: |-50-(-86.62)|=36.62.

[0091] In order to improve the accuracy of performance testing and avoid the impact of path loss on performance testing. As an optional implementation, when the performance indicator includes detection error and the signal processing information at each angle includes the second received signal strength of the signal detection device at the angle, the above S404 may include the following steps: based on the difference between the second received signal strength at the angle and the transmitted signal strength of the second wireless signal at the frequency point, and the path loss from the first antenna to the signal detection device at the frequency point, obtain the detection error of the signal detection device at the angle.

[0092] The embodiment of the present application obtains a first difference by calculating the difference between the second received signal strength at each angle and the transmitted signal strength of the second wireless signal at the corresponding frequency point; calculates the difference between the first difference and the path loss from the first antenna to the signal detection device at the frequency point to obtain a second difference, and based on the second difference, obtains the detection error of the signal detection device at the angle. For example: assuming that the path loss corresponding to frequency 1 is 35.68dB, the signal strength of the first wireless signal transmitted by the first antenna at each angle is -50dBm, the signal detection device receives the signal strength of the first wireless signal at an angle of 0°, that is, the second received signal strength is -88.75dBm, and receives the signal strength of the first wireless signal at an angle of 60°, that is, the second received signal strength is -86.62dBm, then the specific value of the detection error corresponding to the frequency B1 angle of 0°, that is, the first index value is: |-50-35.68-(-88.75)|=3.07, the specific value of the detection error corresponding to the frequency B1 angle of 60°, that is, the first index value is: |-50-35.68-(-86.62)|=0.94.

[0093] In order to improve the accuracy of performance testing, the embodiment of the present application also tests, for each frequency point, the specific value of the detection error of the signal detection device at different angles at the frequency point when the transmission signal strength of the first wireless signal transmitted by the first antenna remains unchanged.

[0094] In order to improve the accuracy of the performance test, the embodiment of the present application also tests and obtains specific values ​​of the detection errors of the signal detection device at different frequency points when the transmission signal strength of the first wireless signal transmitted by the first antenna remains unchanged.

[0095] The embodiment of the present application calculates the specific value of the detection error corresponding to each angle, i.e., the first index value, by targeting the detection error as a performance indicator, through the difference between the second received signal strength at each angle and the second wireless signal transmission signal strength at the frequency point, as well as the path loss at the corresponding frequency point. This can directly measure the detection accuracy of the signal detection device and use it as a performance indicator, which can not only refine the performance test, but also overcome the problem of the failure to fully consider the detection accuracy of the device in the traditional method. By incorporating the detection error into the performance evaluation, the actual performance of the device under different angles and path loss conditions can be more accurately evaluated, further enhancing the accuracy and reliability of the test results, and providing a more comprehensive test solution that can truly reflect the error situation of the device in the actual environment, and improve the effectiveness of the performance test and the ability to predict actual usage.

[0096] As an optional method, when the performance indicators include detection sensitivity; the first wireless signal transmitted at each frequency point includes multiple first wireless signals with transmission signal strengths; the signal processing information at each angle includes the transmission signal strength corresponding to the minimum detection signal strength of the angle, and the minimum detection signal strength is the minimum signal strength detected by the signal detection device at the angle, the detection sensitivity of the signal detection device at the angle can be obtained in the following way: based on the transmission signal strength corresponding to the minimum detection signal strength, determine the detection sensitivity of the signal detection device at the angle.

[0097] In the embodiment of the present application, for each frequency point and each angle, the first antenna is controlled to transmit the first wireless signal at the frequency point, and the transmission signal strength of the first wireless signal transmitted by the first antenna is gradually reduced or increased, and the signal detection device is controlled to detect the first wireless signal at the angle until the signal detection device can just sense the first wireless signal. The transmission signal strength of the first wireless signal transmitted by the first antenna at this time is used as the transmission signal strength corresponding to the minimum detection signal strength of the signal detection device at the angle, and the detection sensitivity of the signal detection device at the angle is determined based on the transmission signal strength corresponding to the minimum detection signal strength at the angle. For example: assuming that for frequency point B1, the transmission signal strength corresponding to the minimum detection signal strength at an angle of 0° is -79, and the transmission signal strength corresponding to the minimum detection signal strength at an angle of 60° is -81, then the specific value of the detection sensitivity corresponding to the frequency point B1 angle of 0°, that is, the first index value, is -79, and the specific value of the detection sensitivity corresponding to the frequency point B1 angle of 60°, that is, the first index value, is -81.

[0098] In order to improve the accuracy of performance testing and avoid the impact of path loss on performance testing. As an optional implementation, when the performance indicators include detection sensitivity; the first wireless signal transmitted at each frequency point includes multiple first wireless signals with transmission signal strengths; the signal processing information at each angle includes the transmission signal strength corresponding to the minimum detection signal strength of the angle, and the minimum detection signal strength is the minimum signal strength detected by the signal detection device at the angle, the above S404 may include the following steps: based on the transmission signal strength corresponding to the minimum detection signal strength, and the path loss from the first antenna to the signal detection device at the frequency point, determine the detection sensitivity of the signal detection device at the angle.

[0099] The embodiment of the present application calculates the difference between the transmission signal strength corresponding to the minimum detection signal strength and the path loss from the first antenna to the signal detection device at the frequency point, and based on the difference, obtains the detection sensitivity of the signal detection device at the angle. For example: Assuming that the path loss corresponding to the frequency point B1 is 35.68dB, for the frequency point B1, the transmission signal strength corresponding to the minimum detection signal strength at an angle of 0° is -79, and the transmission signal strength corresponding to the minimum detection signal strength at an angle of 60° is -81, then the specific value of the detection sensitivity corresponding to the frequency point B1 angle of 0°, that is, the first index value, is -79-35.68=-114.68, and the specific value of the detection sensitivity corresponding to the frequency point B1 angle of 60°, that is, the first index value, is -81-35.68=-116.68.

[0100] The embodiment of the present application determines the specific value of the detection sensitivity corresponding to each angle, i.e., the first index value, by targeting the performance index of detection sensitivity, through the minimum detection signal strength at each angle and its corresponding transmission signal strength, as well as the path loss at the corresponding frequency point. It can measure the sensitivity of the signal detection device at different angles in detail, i.e., the minimum signal strength that the device can detect, which is crucial for the performance evaluation of wireless communication devices, because the sensitivity directly affects the device's ability to detect weak signals. By combining the minimum detection signal strength with the transmission signal strength, the sensitivity of the device can be accurately evaluated, so that the actual detection performance of the device can be better evaluated in the real application environment, and the sensitivity evaluation problem that may be ignored in the traditional test method can be overcome, so that the test results can not only reflect the detection error of the device at different angles and path losses, but also truly reflect the device's ability to detect low signal strengths, and comprehensively improve the accuracy and practicality of performance testing.

[0101] As an optional method, when the performance indicators include reporting sensitivity; the first wireless signal transmitted at each frequency point includes multiple first wireless signals with transmitting signal strengths; the signal processing information at each angle includes the transmitting signal strength corresponding to the minimum reported signal strength of the angle, and the minimum reported signal strength is the minimum signal strength of the angle reported by the signal detection device to the cloud platform, the reporting sensitivity of the signal detection device at the angle can be obtained in the following way: based on the transmitting signal strength corresponding to the minimum reported signal strength, determine the reporting sensitivity of the signal detection device at the angle.

[0102] In the embodiment of the present application, for each frequency point and each angle, the first antenna is controlled to transmit the first wireless signal at the frequency point, and the transmission signal strength of the first wireless signal transmitted by the first antenna is gradually reduced or increased, and the signal detection device is controlled to detect the first wireless signal at the angle, and the detected information about the first wireless signal is reported to the cloud platform, until the signal detection device is just able to upload the signal information cloud platform, and the transmission signal strength of the first wireless signal transmitted by the first antenna at this time is used as the transmission signal strength corresponding to the minimum reported signal strength of the signal detection device at the angle, and the reporting sensitivity of the signal detection device at the angle is determined based on the transmission signal strength corresponding to the minimum reported signal strength at the angle. For example: For example: Assuming that for frequency point B1, the transmission signal strength corresponding to the minimum reported signal strength at an angle of 0° is -76, and the transmission signal strength corresponding to the minimum reported signal strength at an angle of 60° is -75, then the specific value of the reporting sensitivity corresponding to the frequency point B1 angle 0°, that is, the third index value, is -76, and the specific value of the reporting sensitivity corresponding to the frequency point B1 angle 60°, that is, the third index value, is -75.

[0103] In order to improve the accuracy of performance testing and avoid the impact of path loss on performance testing. As an optional implementation, when the performance indicators include reporting sensitivity; the first wireless signal transmitted at each frequency point includes multiple first wireless signals with transmission signal strengths; the signal processing information at each angle includes the transmission signal strength corresponding to the minimum reported signal strength of the angle, and the minimum reported signal strength is the minimum signal strength of the angle reported by the signal detection device to the cloud platform, the above S404 may include the following steps: based on the transmission signal strength corresponding to the minimum reported signal strength, and the path loss from the first antenna to the signal detection device at the frequency point, determine the reporting sensitivity of the signal detection device at the angle.

[0104] The embodiment of the present application calculates the difference between the transmitted signal strength corresponding to the minimum reported signal strength and the path loss from the first antenna to the signal detection device at the frequency point, and based on the difference, obtains the reporting sensitivity of the signal detection device at the angle. For example: Assuming that the path loss corresponding to the frequency point B1 is 35.68dB, for the frequency point B1, the transmitted signal strength corresponding to the minimum reported signal strength at an angle of 0° is -76, and the transmitted signal strength corresponding to the minimum reported signal strength at an angle of 60° is -75, then the specific value of the reporting sensitivity corresponding to the frequency point B1 angle of 0°, that is, the first index value, is -76-35.68=-111.68, and the specific value of the reporting sensitivity corresponding to the frequency point B1 angle of 60°, that is, the first index value, is -75-35.68=-110.68.

[0105] The embodiment of the present application evaluates the performance of the signal detection device in detecting signal strength by targeting the performance indicator of reporting sensitivity, recording the minimum reported signal strength at each angle and its corresponding transmitted signal strength, as well as the path loss at the corresponding frequency. Compared with the minimum detection signal strength, reporting sensitivity focuses on the minimum signal strength that the device can effectively report to the cloud platform, which can ensure that the device can not only detect the signal locally, but also successfully report the signal in the remote system, thereby providing the device with the ability to transmit and report signals in actual applications. By combining the signal processing information of the frequency and angle, the comprehensiveness of the performance evaluation is improved, so that the test results can more truly reflect the actual reporting capability of the device under different operating conditions, and achieve refined evaluation, which can ensure the reliability and data transmission capability of the wireless device in the actual operating environment, and enhance the practicality and accuracy of the overall performance test.

[0106] S406: Determine a second indicator value of the performance indicator at the frequency point based on the first indicator values ​​of the performance indicator at multiple angles.

[0107] The second indicator value is a specific value of the performance indicator corresponding to each frequency point.

[0108] As an optional method, the above S406 may include the following steps: based on the maximum value of the first indicator values ​​of the performance indicator at multiple angles, determine the second indicator value of the performance indicator at the frequency point. For example: in the case where the performance indicator is the detection error, assuming that for the frequency point B1, the specific value of the detection error corresponding to each angle, that is, the first indicator value is as follows: the detection error corresponding to 0° is 3.07, the detection error corresponding to 60° is 0.94, the detection error corresponding to 120° is 1.29, the detection error corresponding to 180° is 4.23, the detection error corresponding to 240° is 2.73, and the detection error corresponding to 300° is 5.58, then the maximum value is the detection error corresponding to 300°, that is, 5.58, therefore, the specific value of the detection error corresponding to the frequency point B1, that is, the second indicator value is 5.58.

[0109] As another optional method, the second indicator value of the performance indicator at each frequency point can also be determined by: determining the second indicator value of the performance indicator at the frequency point based on the average value of the first indicator values ​​of the performance indicator at multiple angles, wherein the average value can be obtained by a simple arithmetic mean or by a square root of a square sum.

[0110] As an optional manner, when the performance indicator includes the detection error, the above S406 may include the following step: determining a second indicator value of the detection error at the frequency point based on the maximum value of the first indicator values ​​of the detection error at multiple angles.

[0111] As an optional method, when the performance index includes detection sensitivity, the above S406 may include the following steps: determining a second index value of the detection sensitivity at the frequency point based on the maximum value of the first index values ​​of the detection sensitivity at multiple angles.

[0112] As an optional manner, when the performance indicator includes upload sensitivity, the above S406 may include the following step: determining a second indicator value of the upload sensitivity at the frequency point based on the maximum value of the first indicator values ​​of the upload sensitivity at multiple angles.

[0113] The embodiment of the present application calculates the specific value of the performance indicator corresponding to each angle, i.e., the first indicator value, based on the signal processing information at each angle, and then determines the specific value of the performance indicator corresponding to each frequency point, i.e., the second indicator value, based on the first indicator value. This can more accurately capture the performance changes of the signal detection device at different angles, thereby comprehensively reflecting the actual performance of the device in the actual use environment. The angle-subdivided measurement method can more comprehensively evaluate the impact of the antenna module and the device housing on the signal strength, and provide a more accurate and comprehensive performance evaluation.

[0114] S408: Determine a third indicator value of the performance indicator based on the second indicator values ​​of the performance indicator at multiple frequency points.

[0115] The third index value is a specific value reflecting the overall performance index of the signal detection device.

[0116] As an optional method, the above S408 may include the following steps: determining a third indicator value of the performance indicator based on the maximum value of the second indicator values ​​of the performance indicator at multiple frequency points. For example, in the case where the performance indicator is a detection error, assuming that the specific values ​​of the detection errors corresponding to the frequency points, that is, the second indicator values, are as follows: the detection error corresponding to B1 is 5.58, the detection error corresponding to B2 is 7.81, and the detection error corresponding to B3 is 5.69, then the maximum value is the detection error corresponding to B2, that is, 5.58, and therefore, the specific value of the detection error of the signal detection device, that is, the third indicator value, is 5.58.

[0117] As another optional method, the third indicator value of the performance indicator can also be determined by: determining the third indicator value of the performance indicator based on the average value of the second indicator values ​​of the performance indicator at multiple frequency points, wherein the average value can be obtained by a simple arithmetic mean or by a square root of the sum of squares.

[0118] As an optional manner, when the performance indicator includes the detection error, the above S408 may include the following step: determining a third indicator value of the detection error based on the maximum value of the second indicator values ​​of the detection error at multiple frequency points.

[0119] As an optional manner, when the performance indicator includes detection sensitivity, the above S408 may include the following step: determining a third indicator value of the detection sensitivity based on the maximum value of the second indicator values ​​of the detection sensitivity at multiple frequency points.

[0120] As an optional manner, when the performance indicator includes upload sensitivity, the above S408 may include the following step: determining a third indicator value of the upload sensitivity based on the maximum value of the second indicator values ​​of the upload sensitivity at multiple frequency points.

[0121] In practical applications, the signal detection device is only used to detect signals at one or several frequency points, and does not need to cover all frequency points. Therefore, in order to indicate the detection error of the signal detection device at different frequency points, the detection error of the device can also be identified by frequency points. As an optional implementation method, the above S408 may include the following steps: using the second indicator values ​​of the performance indicators at multiple frequency points as the third indicator value of the performance indicator.

[0122] The embodiment of the present application controls the first antenna to transmit the first wireless signal at multiple frequencies. For each frequency, the signal detection device performs signal processing at multiple angles to obtain signal processing information at multiple angles. For each angle, based on the signal processing information at the angle and the path loss from the first antenna to the signal detection device at the frequency, the first indicator value of the performance indicator at the angle is determined. Then, based on the first indicator values ​​of the performance indicator at the multiple angles, the second indicator value of the performance indicator at the frequency is determined. Thus, based on the second indicator values ​​of the performance indicator at the multiple frequencies, the third indicator value of the performance indicator is obtained. The accuracy of the performance test can be improved, and the performance indicator data reflecting the overall true level of the signal detection device can be used to comprehensively evaluate the performance of the device in the actual use environment. Based on the signal processing information at different angles at different frequencies, a true reflection of the overall performance of the signal inspection device can be obtained. The influence of the antenna module and the device casing on the signal is fully considered, so that the test results will more accurately reflect the performance of the device under actual use conditions, thereby improving the accuracy and reliability of wireless network quality assurance.

[0123] In some embodiments, the signal detection device may be a polyhedron, and further, each face of the signal detection device may be tested to obtain a third indicator value of the performance indicator, and based on the third indicator values ​​of the performance indicator on different faces, the performance indicators of the signal detection device in different dimensions may be obtained. The signal detection device may be subjected to multi-dimensional performance testing and evaluation to improve the accuracy of the performance test.

[0124] In actual application, the signal detection device may be used to detect signals in a variety of environments. Considering the impact of the environment on the performance test of the signal detection device, the embodiment of the present application also simulates the actual environment and places the signal detection device in a simulated environment for performance testing to improve the accuracy of the performance test. When the device is subsequently put into use in an actual environment, the network operation and quality in the actual environment can be accurately judged based on the signal strength detected by the device. For example: Figure 5A In the test scenario shown, the signal detection device is placed in a dark room, where the dark room is a pre-simulated specific environmental space.

[0125] After obtaining the third indicator value of the performance indicator of the signal detection device, the performance of the signal detection device can also be evaluated according to the third indicator value of the performance indicator. Specifically, it is determined whether the third indicator value meets the preset threshold range. If it does, it is determined that the performance indicator of the signal detection device meets the use requirements, so as to evaluate the performance of the signal detection device and determine the signal detection device that meets the requirements, which is helpful for the procurement department to purchase suitable signal detection equipment and put it into use. For example: assuming that the actual use requires that the detection sensitivity of the signal detection device meets the preset range of -200~-100dBm, then when the third indicator value of the detection sensitivity of the signal detection device is -112.75dBm, it is determined that the detection sensitivity of the signal detection device meets the actual use requirements.

[0126] After obtaining the third indicator value of the performance indicator of the signal detection device, a test report can also be generated based on the test data, so as to evaluate the performance of the detection device according to the test report, and trace the test process to control the quality of the operation specifications of each test link. Among them, the test data may include the first indicator value, the second indicator value, the third indicator value of the performance indicator, and the corresponding signal processing information at each angle at different frequencies, and the intermediate data involved in the calculation process of each indicator value, such as the data shown in Tables 6 to 15.

[0127] The following is a complete example to illustrate the performance test method of the signal detection device provided in the embodiment of the present application, which should not be understood as limiting the method of the embodiment of the present application. Figure 5A , is a schematic diagram of a performance test scenario of a signal detection device provided by an embodiment of the present application. Figure 5AAs shown, the scene includes a control room and a darkroom. The control room includes a comprehensive tester, a computer and a turntable controller. The darkroom includes a first antenna and its bracket, a signal detection device, and a turntable. The signal detection device is placed on the turntable. The turntable is connected to the turntable controller. The turntable controller controls the turntable to rotate, thereby changing the angle of the signal detection device. The comprehensive tester is connected to the first antenna. The comprehensive tester controls the first antenna to transmit wireless signals and controls the frequency and signal strength of the wireless signals. The computer is connected to the signal detection device, and the signal information detected by the signal detection device is obtained through the computer.

[0128] First, the path loss measurement process is described. Figure 5B , is a schematic diagram of a path loss calibration scenario provided by an embodiment of the present application. Figure 5B As shown, the scene includes a control room and a darkroom. The control room includes a comprehensive tester, a spectrum analyzer and a turntable controller. The darkroom includes a first antenna and its bracket, a second antenna, and a turntable. The second antenna is placed on the turntable. The turntable is connected to the turntable controller. The turntable is controlled to rotate by the turntable controller so that the second antenna is aligned with the first antenna. The comprehensive tester is connected to the first antenna. The comprehensive tester controls the first antenna to transmit wireless signals and controls the frequency and signal strength of the wireless signals. The signal of the comprehensive tester is transmitted to the first antenna in the darkroom by wire. The spectrum analyzer is connected to the second antenna, and the spectrum analyzer records the signal strength received by the second antenna. During measurement, the signal strength of the signal transmitted by the first antenna, that is, the transmission signal strength, is set by the comprehensive tester and remains unchanged. For each frequency point, the comprehensive tester controls the first antenna to transmit the signal of the corresponding frequency point, and the spectrum analyzer records the received signal strength of the second antenna. Repeat the above steps to obtain the received signal strength of the second antenna at multiple frequency points. For example, the recording results and the path loss of each frequency point are shown in Table 1.

[0129] Table 1

[0131] in, (1).

[0132] It should be understood that the path from the second antenna to the first antenna is the same as the path from the signal detection device to the first antenna, and the environment inside the darkroom remains unchanged.

[0133] Next is the test description of each performance indicator.

[0134] Detection error: Figure 5AAs shown, place the signal detection device at the center of the turntable. Connect the signal detection device to the computer in the control room via a wired method (such as a serial port or a network cable) to read the detection results of the signal detection device. Since the relative angle relationship with the signal transmitting antenna cannot be ensured when the signal detection device is installed, it is necessary to test the detection error of the device at each angle. Use the turntable controller to control the turntable in the darkroom, rotate the turntable at a certain angle step, drive the signal detection device to rotate, and test the received signal strength of the device at each angle when it faces the transmitting antenna. For details, please refer to Figure 5C , is a flow chart of a detection error test provided by an embodiment of the present application. Figure 5C As shown, first, through Figure 5B The scenario shown in the figure completes the path loss measurement and calibration, and then Figure 5A In the scenario shown, the received signal strength of the signal detection device at different angles in the 360° direction at a certain frequency is measured. By repeating the above steps, the received signal strength of the signal detection device at different angles in the 360° direction at other frequencies is measured until all frequency points are measured. Then, based on the measured received signal strength, the detection error value of the signal detection device at different frequencies and different angles is calculated. For a certain frequency, the maximum value of the error of the signal detection device at different angles in 360° is the detection error of the device at that frequency, and the detection error of the signal detection device is the maximum value of the detection error of all frequencies. For example: The signal strength transmitted by the comprehensive tester at each frequency is , signal detection equipment at all angles Received signal strength at each frequency point , as shown in Table 2.

[0148] Detection sensitivity test: Figure 5A As shown, place the device on a turntable, set a certain frequency point and a certain angle, and the comprehensive tester gradually reduces the transmission intensity until the device can no longer detect wireless signal strength and other information. For details, please refer to Figure 5D , is a schematic diagram of a detection sensitivity test flow provided by an embodiment of the present application. Figure 5D As shown, first, through Figure 5B The scenario shown in the figure completes the path loss calibration and then passes Figure 5A In the scenario shown, set a certain frequency point and a certain angle, and the comprehensive tester gradually reduces the transmitted signal strength until the signal detection device cannot detect the signal information. Record the transmitted signal strength of the comprehensive tester. Then, keep the frequency point unchanged and change the angle. The comprehensive tester gradually reduces the transmitted signal strength until the signal detection device cannot detect the signal information. Record the transmitted signal strength of the comprehensive tester. Repeat the previous two steps to measure other frequency points and different angles. Test the minimum value of the signal strength that the comprehensive tester needs to transmit when the signal detection device can detect the signal information. For a certain frequency point, when the device can detect the signal information at different angles of 360°, the maximum value of the transmitted signal strength required by the comprehensive tester is the detection sensitivity of the device at that frequency point. The detection sensitivity of the device is the maximum value of the detection sensitivity of the device at all frequency points. For example: the transmitted signal strength of the comprehensive tester is , as shown in Table 4.
