[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

It is also readily understood that the modules, units, or processing methods in the various embodiments described herein and shown in the accompanying drawings can be combined and designed in various different configurations. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] The definitions of various terms or methods used in the following embodiments are, except where logically impossible, generally defined as broad concepts that can be implemented under the premise of the content disclosed in the embodiments. Under this understanding, all specific subordinate limitations of the terms or methods should be considered as part of the invention and should not be narrowly interpreted or biased simply because the specification does not disclose such a specific limitation. Similarly, provided that it is logically feasible, the order of the steps in the method is flexible and varied, and all specific subordinate limitations in the broad concepts of various terms or methods fall within the scope of protection of this invention.

[0052] The main solution of this application embodiment is: to obtain preset signal parameters, then control the radio frequency transmitter under test to emit a first radio frequency signal according to the test setting parameters, then adjust the first radio frequency signal according to the preset signal parameters to obtain a second radio frequency signal, then output the second radio frequency signal to the radio frequency test board, and obtain the first received bit error rate output by the radio frequency test board to determine whether the radio frequency transmitter under test is qualified.

[0053] In this embodiment, for ease of description, the identification control device will be used as the execution subject in the following description.

[0054] Because existing technology lacks corresponding testing and screening mechanisms for the quality of radio frequency signals emitted by radio frequency transmitters.

[0055] This application provides a solution that enables the testing of the signal quality of radio frequency transmitted signals without the need for radio frequency test instruments, thereby reducing testing costs and difficulty.

[0056] Therefore, the present invention proposes a control method for a radio frequency signal detection device; it is understood that the detection device is equipped with a control device for storing and executing the following method. The control device can be implemented by a main controller, such as an MCU (Micro Controller Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or a SOC (System On Chip).

[0057] Reference Figure 1 , Figure 1 This is a schematic flowchart of a control method for a radio frequency signal detection device according to an embodiment of the present invention. In one embodiment of the present invention, the control method includes steps S100-S400, wherein:

[0058] S100, Obtain preset signal parameters;

[0059] S200: Control the radio frequency transmitter under test to work according to the test setting parameters so that it emits a first radio frequency signal, and adjust the first radio frequency signal according to the preset signal parameters to obtain a second radio frequency signal;

[0060] S300: Output the second radio frequency signal to the radio frequency test board and obtain the first received bit error rate output by the radio frequency test board;

[0061] S400. Determine whether the radio frequency transmitter under test is qualified based on the first received bit error rate.

[0062] In this embodiment, the preset signal parameters may include, but are not limited to, key parameters such as frequency, power, modulation method, and encoding method. These parameters directly affect the operating status of the RF transmitter and the quality of the RF signal. The preset signal parameters can be obtained by reading a configuration file, receiving user input, or querying a database. These preset signal parameters will be used to subsequently control the operating status of the RF transmitter under test.

[0063] In this embodiment, the RF transmitter under test is controlled to operate according to the test settings parameters, that is, the transmitter is set to transmit a first RF signal according to preset signal parameters (such as frequency, power, etc.). Simultaneously, based on preset modulation and encoding methods, the first RF signal emitted by the transmitter is adjusted as necessary to obtain a second RF signal that meets the test requirements. The adjusted second RF signal is then output to the RF test board. The RF test board is a hardware device specifically designed for receiving and evaluating RF signals. It can receive RF signals from the transmitter and measure various performance indicators of the signal, such as bit error rate, power spectral density, and spectral purity. The first received bit error rate output by the RF test board is then obtained. The bit error rate is one of the important indicators for measuring the quality of RF signals; it represents the ratio of the number of erroneous bits during transmission to the total number of bits. By comparing the first received bit error rate with a preset pass / fail standard, we can determine whether the RF transmitter under test is qualified.

[0064] In this embodiment, for example, the preset signal parameters are 10dB, the test settings are a transmit power of 10W, a modulation method of quadrature phase shift keying, and an encoding method of low-density parity-check code. When the RF transmitter under test operates according to these parameter settings, it will emit a first RF signal. After the RF transmitter under test emits the first RF signal according to these parameters, the control device will monitor and adjust the signal in real time to ensure that its power is stable and meets the preset 10dB standard. The adjustment process may include adjusting the transmitter's output power, frequency correction, phase calibration, etc., to ensure the stability and accuracy of the output signal. After the second RF signal is output to the RF test board, the RF test board outputs the first receive bit error rate. This bit error rate reflects the quality of the RF signal during transmission. If the first receive bit error rate is lower than the preset pass standard, such as 1e-6, it indicates that the RF signal emitted by the RF transmitter under test is of good quality, and the RF transmitter is judged to be qualified. Conversely, if the first receive bit error rate is higher than the preset pass standard, it indicates that there are many errors in the RF signal during transmission, and the RF transmitter is judged to be unqualified.

[0065] Furthermore, refer to Figure 2 Another embodiment of the present invention provides a control method for a radio frequency signal detection device, based on the above. Figure 1 The illustrated embodiment involves controlling the radio frequency transmitter under test to operate according to test setting parameters to emit a first radio frequency signal, and adjusting the first radio frequency signal according to preset signal parameters to obtain a second radio frequency signal. The steps include S210-S230, wherein:

[0066] S210. Control the radio frequency transmitter under test to send out the first radio frequency signal according to the test setting parameters;

[0067] S220. Determine the attenuation value corresponding to the attenuator based on the first radio frequency signal and the preset signal parameters;

[0068] S230. Adjust the power value of the first radio frequency signal according to the attenuation value to obtain the second radio frequency signal.

[0069] In this embodiment, the test setup parameters may include the transmitter's output power, frequency, modulation method, etc. To more accurately control the quality of the radio frequency (RF) signal, an attenuator is used for adjustment. The attenuator can determine a suitable attenuation value based on the first RF signal and preset signal parameters, thereby adjusting the power value of the first RF signal to obtain a second RF signal that meets the preset requirements. The attenuator can be an electronic component, such as an adjustable resistor, which can reduce the power of a signal without changing its frequency or waveform. In RF communication systems, attenuators are commonly used to adjust the power level of a signal to meet specific test or communication requirements.

[0070] In this embodiment, after the radio frequency transmitter under test emits a first radio frequency signal according to the test settings, the control device monitors the signal in real time and, in conjunction with preset signal parameters such as target power value and frequency, determines whether the first radio frequency signal needs adjustment. If adjustment is required, the control device calculates the attenuation value corresponding to the attenuator based on the current power value of the first radio frequency signal and the target power value in the preset signal parameters. This attenuation value is actually a quantized value of power attenuation, used to control the degree of power attenuation of the first radio frequency signal by the attenuator. Based on the calculated attenuation value, the control device sends a control command to the attenuator, causing the attenuator to adjust the power value of the first radio frequency signal according to the specified attenuation value. The adjusted radio frequency signal, i.e., the second radio frequency signal, will have a power value closer to the target power value in the preset signal parameters, thereby improving the stability and accuracy of the radio frequency signal.

[0071] Furthermore, refer to Figure 3 Another embodiment of the present invention provides a control method for a radio frequency signal detection device, based on the above. Figure 1 The illustrated embodiment includes steps S410-S430, whereby the step of determining whether the radio frequency transmitter under test is qualified based on the first received bit error rate includes:

[0072] S410. Determine whether the radio frequency transmitter under test is qualified based on the first received bit error rate and the first bit error rate threshold.

[0073] S420. If the first received bit error rate is lower than the first bit error rate threshold, the radio frequency transmitter under test is determined to be qualified.

[0074] S430. If the first received bit error rate is higher than the first bit error rate threshold, the radio frequency transmitter under test is determined to be unqualified.

[0075] In this embodiment, the first bit error rate threshold can be a standard value set according to actual needs, used to determine whether the bit error rate of the received radio frequency signal is within an acceptable range. This first bit error rate threshold is usually set based on factors such as the performance requirements of the radio frequency communication system, the reliability of signal transmission, and the actual test environment.

[0076] In this embodiment, by comparing the first received bit error rate with a first bit error rate threshold, if the first received bit error rate is lower than the first bit error rate threshold, then the number of erroneous bits occurring during signal transmission is smaller, and the signal quality is higher. Therefore, it can be determined that the radio frequency transmitter under test is qualified. At this point, we can continue with subsequent tests or put it into actual use.

[0077] However, if the first received bit error rate (BER) exceeds the first BER threshold, it indicates that numerous errors have occurred during signal transmission. This could be due to unstable performance, misconfiguration, or other factors of the RF transmitter under test. In this case, further inspection or adjustment of the RF transmitter under test is necessary to ensure its proper functioning and compliance with test requirements.

[0078] Furthermore, to improve the accuracy and reliability of testing, we can consider introducing a mechanism of multiple tests. For example, we can continuously send multiple radio frequency signals and record their bit error rates separately, then calculate the average of these bit error rates as the final judgment criterion. This can reduce the random errors that may exist in a single test and improve the accuracy of the test.

[0079] Furthermore, refer to Figure 4 Another embodiment of the present invention provides a control method for a radio frequency signal detection device, based on the above. Figure 1 The illustrated embodiment includes a radio frequency test board comprising a transmitter and a receiver, and the method further includes steps S500-S700, wherein:

[0080] S500 controls the transmitter of the RF test board to transmit test signals and acquires the first signal parameters of the corresponding transmitted test signals output by the receiver;

[0081] S600. Adjust the transmitter's settings until the first signal parameter matches the preset signal parameter;

[0082] S700, use the adjusted settings as the test settings.

[0083] In this embodiment, the RF test board not only serves as a device for receiving and evaluating signals emitted by the RF transmitter under test, but also functions as a transmitter of test signals. By controlling the transmitter of the RF test board to transmit test signals, we can obtain the first signal parameters of the corresponding transmitted test signal output by the receiver. These first signal parameters include, but are not limited to, power, frequency, and phase, which reflect the performance of the test signal during transmission.

[0084] In this embodiment, to ensure the accuracy and reliability of the test, it is also necessary to ensure that the signal emitted by the RF test board itself conforms to a preset standard. Therefore, after obtaining the first signal parameter, we compare it with the preset signal parameter. If there is a difference, we adjust the transmitter settings, such as output power and frequency, until the first signal parameter matches the preset signal parameter. The above adjustment process can be performed automatically or manually, depending on the configuration of the test equipment and the test requirements. Once the first signal parameter matches the preset signal parameter, we use the adjusted settings as the test settings for subsequent testing of the RF device under test. This ensures that the RF test board itself can emit a test signal that conforms to the standard, providing a reliable benchmark for subsequent RF transmitter testing.

[0085] Furthermore, refer to Figure 5 In another embodiment of the present invention, a control method for a radio frequency signal detection device is provided, based on the above. Figure 4 The embodiment shown includes steps S610-S630, whereby: Adjusting the transmitter's settings parameters until the first signal parameter matches the preset signal parameter.

[0086] S610: Obtain the actual strength data of the test signal output by the transmitter;

[0087] S620. Calibrate the test signal based on the actual intensity data and preset signal parameters;

[0088] S630. Generate the transmission signal data corresponding to the radio frequency transmitter under test based on the calibrated test signal.

[0089] In this embodiment, the true intensity data is the power intensity value of the test signal output by the transmitter, directly measured by professional measuring equipment. This data accurately reflects the actual intensity of the test signal. After acquiring the true intensity data, the control device compares it with the target intensity value in the preset signal parameters. If a difference exists, the control device calibrates the test signal based on the true intensity data. The calibration process may include adjusting the transmitter's output power, optimizing the signal modulation method, etc., to ensure that the test signal maintains a stable intensity during transmission and conforms to the preset signal standard. For example, assuming the preset signal parameter is 10dB and the true intensity parameter is 6dB, the true intensity parameter needs to be adjusted to 10dB. After calibration, the transmission signal data corresponding to the RF transmitter under test is generated based on the calibrated test signal. This transmission signal data is used to evaluate the signal quality transmitted by the RF transmitter under test under specific conditions. The process of generating the transmission signal data may consider various factors, such as the signal modulation method, frequency allocation, and time slot planning, to ensure the accuracy and reliability of the test signal.

[0090] Furthermore, refer to Figure 6 Another embodiment of the present invention provides a control method for a radio frequency signal detection device, based on the above. Figure 4 The embodiment shown further includes S800-S1000, wherein:

[0091] S800: Obtain the sensitivity of the receiver to receive signals under the third radio frequency signal;

[0092] S900, Increase the output power of the third radio frequency signal to reduce the signal quality emitted by the standard instrument to the quality limit;

[0093] S1000: After the signal quality is at the quality limit, adjust the output power of the third radio frequency signal until the second receiving bit error rate of the receiver is lower than the threshold.

[0094] In this embodiment, sensitivity is the receiver's critical signal strength value. For example, given a signal strength of -50dB and a bit error rate threshold of 10%, assuming it's exactly 10%, any further signal strength would result in the receiver being unable to resolve the signal. In this case, -50dB is the receiver's sensitivity. To test and optimize receiver performance, we can simulate different signal quality conditions by controlling the output power of different RF signals and observe the receiver's response.

[0095] First, the receiver's sensitivity to the received signal under the third radio frequency (RF) signal is determined. This is typically done by sending an RF signal close to but slightly below the sensitivity threshold, and then observing the receiver's bit error rate (BER) or signal resolution capability. Next, the output power of the third RF signal is increased to simulate a gradual decrease in signal quality. Throughout this process, the control unit continuously monitors the receiver's performance, particularly changes in the BER. When the BER reaches or approaches a preset quality limit, the signal quality is considered to be at a critical state.

[0096] Then, once the signal quality is within its limits, the output power of the third radio frequency signal is adjusted. The goal of this adjustment process is to find a suitable output power value that ensures the receiver's second bit error rate is below a preset threshold. This threshold is typically set based on actual application requirements or industry standards to ensure the receiver can stably receive and resolve signals under normal operating conditions, effectively testing and optimizing receiver performance.

[0097] In this embodiment, the receiver calibration process requires calibrating both the signal strength and signal quality of the receiver to a preset standard. Once the signal quality is determined, the signal strength needs to be reduced to the sensitivity level. Under the current signal quality, the critical signal strength is searched to determine the packet error rate of the receiver and find a limit value. This limit value is the sensitivity limit of the receiver under this condition.

[0098] Furthermore, refer to Figure 7 Another embodiment of the present invention provides a control method for a radio frequency signal detection device, based on the above. Figure 6 The illustrated embodiment includes steps S1010-S1020, whereby: The step of adjusting the output power of the third radio frequency signal until the receiver's second received bit error rate is below a threshold is S1010-S1020.

[0099] S1010: The signal strength of the third radio frequency signal is reduced to the sensitivity of the receiver signal by the attenuator to generate the fourth radio frequency signal;

[0100] S1020: Control the receiver to receive the fourth radio frequency signal, and after the receiver receives it, determine that the second received bit error rate is lower than the second bit error rate threshold, and record the signal strength of the fourth radio frequency signal received by the receiver.

[0101] In this embodiment, an attenuator is a device used to reduce signal strength. It simulates the attenuation a signal may experience during transmission by reducing the signal power. By using an attenuator, the strength of the radio frequency signal can be precisely controlled, allowing for accurate testing and calibration of the receiver's performance.

[0102] First, the signal strength of the third radio frequency (RF) signal is reduced to the receiver's sensitivity using an attenuator, thus generating the fourth RF signal. In essence, the reduced third RF signal can be directly identified as the fourth RF signal. The key to this step is accurately setting the attenuation level of the attenuator to ensure that the strength of the fourth RF signal matches the receiver's sensitivity. This simulates signal strength conditions close to those in a real-world operating environment, allowing for a more realistic test of the receiver's performance.

[0103] Next, the receiver receives the fourth radio frequency signal, and after reception, it uses testing equipment or software to determine whether the second received bit error rate is lower than a preset second bit error rate threshold. This threshold is set according to the receiver's performance requirements and application scenario, and is used to evaluate the receiver's signal resolution capability under critical signal strength conditions.

[0104] If the second received bit error rate is lower than the second bit error rate threshold, then the receiver can be considered to be able to stably receive and resolve the signal under that signal strength. At this point, the signal strength of the fourth radio frequency signal received by the receiver is recorded; this value is the receiver's sensitivity limit under that condition. This value is of great significance for subsequent receiver performance evaluation and optimization.

[0105] Furthermore, refer to Figure 8 Another embodiment of the present invention provides a control method for a radio frequency signal detection device, based on the above. Figure 7 The illustrated embodiment includes steps S1021-S1023, whereby the receiver controls the receiver to receive a fourth radio frequency signal, and after receiving the signal, determines that the second received bit error rate is lower than a second bit error rate threshold, and records the signal strength of the fourth radio frequency signal received by the receiver.

[0106] S1021. Control the receiver to receive the fourth radio frequency signal, and after the receiver receives it, determine whether the second receiving bit error rate is lower than the second bit error rate threshold.

[0107] S1022. If the second received bit error rate is lower than the second bit error rate threshold, determine that the strength of the fourth radio frequency signal meets the signal quality detection requirements.

[0108] S1023. If the second received bit error rate is higher than the second bit error rate threshold, adjust the attenuation value of the attenuator to make the second received bit error rate lower than the second bit error rate threshold, and record the signal strength of the fourth radio frequency signal received by the receiver.

[0109] In this embodiment, a real-time monitoring and adjustment mechanism for the received bit error rate (BER) is added to ensure that the receiver maintains stable performance when receiving signals. After controlling the receiver to receive the fourth radio frequency signal, the control device immediately determines whether the second received BER is lower than a preset second BER threshold. If the second received BER is lower than the second BER threshold, it indicates that the reception performance under the current signal strength meets our requirements. We can then determine that the strength of the fourth radio frequency signal meets the signal quality detection requirements and record the signal strength at this time.

[0110] However, if the second received bit error rate (BER) is higher than the second BER threshold, it indicates that the reception performance under the current signal strength is not ideal. To improve this situation, the control device can adjust the attenuation value of the attenuator to reduce the strength of the fourth radio frequency signal and then control the receiver to receive the adjusted signal again. This process will continue until the second received BER drops below the preset second BER threshold. Only then will the control device record the signal strength at this time and consider that the signal strength meets the signal quality detection requirements.

[0111] In this embodiment, this dynamic adjustment mechanism ensures that we find the receiver's optimal operating point during testing—that is, minimizing signal strength while maintaining reception performance—thereby saving energy and improving equipment durability. Simultaneously, because we can monitor and adjust the receive bit error rate in real time, we can more accurately evaluate the receiver's performance and provide strong data support for subsequent optimization and improvement.

[0112] The present invention also proposes a control device, which includes: a memory, a processor, and a control program for a radio frequency signal detection device stored in the memory and executable on the processor. The control program for the radio frequency signal detection device is configured to implement the control method for the radio frequency signal detection device as described above.
