Description

TECHNICAL FIELD

[0001] The technical field related to the present application is signal detection, and particularly relates to a signal detection device based on a communication module. BACKGROUND

[0002] In the current 5G indoor distribution system, signal detection usually relies on a relatively traditional technical solution. This solution uses a frequency shift chip to downshift high-frequency signals to low frequencies, so as to facilitate subsequent wireless receiving chips for processing and analysis. Through this process, the system can demodulate the converted signals, and then realize effective monitoring of 5G signals. However, although this solution has achieved signal reception and conversion to some extent, it still has significant shortcomings. First, in the process of signal frequency shifting, a certain degree of signal attenuation and noise may be introduced, which not only leads to a decrease in signal quality, but also adversely affects subsequent signal processing, thereby increasing the risk of errors. In addition, the processing capacity of this solution is relatively limited, mainly focusing on obtaining the received signal strength (RSRP) and the information of the corresponding frequency band, and cannot fully capture more rich signal characteristics. This limitation makes the system perform poorly in complex environments, and cannot meet the demand for multi-dimensional analysis of 5G signals. Therefore, in view of the deficiencies of the prior art, it is urgent to develop a more efficient and comprehensive 5G signal detection solution to improve the overall quality and processing capacity of the signal, so as to better adapt to the rapid development of communication technology and increasingly complex application scenarios.

[0003] For example, the active frequency shift indoor distribution system and the monitoring method of passive antenna power in the system disclosed in China Patent Network have the application number CN202410324078.2. This solution uses a frequency shift chip to downshift high-frequency signals to low frequencies, and in the process of frequency shifting, a certain degree of signal attenuation and noise is introduced with a high probability.

[0039] In some embodiments, the working mode of the device is disclosed Figures 1 to 8 .

[0040] The main control chip of the embodiment is a Lierda Cat.1 module (Cat.1 module), which is responsible for performing multiple key functions, including 4G signal detection, communication with the redcap module through UART to obtain 5G signal detection data, reporting 4G and 5G monitoring data to the supervision platform, and receiving downlink instructions from the supervision platform, such as detection period setting and detection frequency band setting. This design not only enhances the flexibility of signal monitoring, but also improves the efficiency of data communication.

[0041] Referring to the circuit design of Figures 2 to 8 , the pin configuration of the Cat.1 module optimizes the stability and anti-interference ability of the signal. Specifically, the 11th pin of the Cat.1 module is connected with the first terminal of the resistance R1, and the second terminal of the resistance R1 is connected with the first terminal of the capacitor C10, and the second terminal of the capacitor C10 is grounded. This connection mode effectively forms a low-pass filter to eliminate high-frequency noise and enhance the quality of the signal.

[0042] Similarly, the 12th pin of the Cat.1 module is connected with the capacitor C9 through the resistance R2, and the other end of the capacitor C9 is grounded, constituting another filter, and the connection of the 13th pin with the resistance R3 and the capacitor C8 also follows the same principle. Such design ensures that the signal can maintain good level when passing through these elements, and reduces signal distortion.

[0043] In terms of signal connection, the 1st, 10th, 29th and 36th pins of the Cat.1 module are all grounded, ensuring the common ground reference of the circuit and reducing the interference of the ground loop. In addition, the grounding design of the 44th, 43rd, 40th and 39th pins further enhances the stability of the circuit.

[0044] The 37th pin of the Cat.1 module is connected to a 50Ω radio frequency trace impedance, ensuring the correct matching of the radio frequency signal and reducing the reflection loss. The 45th pin and the 46th pin are also connected with the radio frequency trace impedance, and the second terminals of the capacitors C1, C3 and C5 are connected with the radio frequency trace impedance to realize the effective transmission of high-frequency signals. The connection design of capacitors C2 and C4 also follows the same principle, which ensures the integrity of the signal by grounding.

[0045] In terms of signal monitoring, the 26th pin of Cat.1 is connected to the ground through capacitor C11, further enhancing the stability of the signal. The introduction of voltage stabilizing diode D2 provides overvoltage protection for the radio frequency signal, ensuring that the circuit can still work normally under high load conditions.

[0046] The redcap module is mainly responsible for the detection of 5G signals, and its 36th, 22nd, 19th, 10th, 9th, 8th, 72nd, and 56th pins are all grounded to ensure the stability and anti-interference ability of the circuit. The 57th, 58th, 59th, and 60th pins of the redcap module are connected to the radio frequency impedance, forming an efficient signal processing network. The connection mode of capacitors C21, C23, C25, and C27 is also to connect their first end to the radio frequency impedance and the second end to the ground, ensuring the effective transmission of high-frequency signals.

[0047] On this basis, the 69th pin and the 70th pin of the redcap module are connected to the 3rd pin and the 2nd pin of the burning interface J2 respectively, which is convenient for firmware burning and debugging. The 71st pin is connected to the 1st pin of the burning interface through resistor R22, ensuring the stability of the signal during the burning process.

[0048] During data transmission, the Cat.1 module master control chip communicates with the redcap module through the UART interface. This communication method is not only efficient, but also can obtain real-time detection data of 5G signals. Through accurate time control and data format management, the reliability and accuracy of data transmission are ensured. The Cat.1 module integrates the monitoring data of 4G and 5G and uploads it to the supervision platform.

[0049] During data reporting, the Cat.1 module also receives downlink instructions from the supervision platform, which can flexibly adjust the detection period and frequency band settings. This dynamic management method enables the system to optimize according to actual needs, thereby improving the efficiency and accuracy of signal monitoring.

[0050] In order to facilitate user monitoring of signal status, the Cat.1 module is connected with light emitting diodes LED1 and LED2. MOS tubes DQ1 and DQ2 control the status of LED1 and LED2 respectively, indicating the working status of 4G and 5G signals. The design of resistors R6 and R7 ensures the stable operation of MOS tubes, while the status of light emitting diodes provides instant signal feedback for users.

[0051] In the design of this embodiment, the selection and switching of antennas are also crucial. The master control chip can intelligently select the antenna connected to the Cat.1 module or the redcap module according to the current signal detection needs. Through the control circuit, it ensures that during the scanning of 4G and 5G signals, the system can flexibly switch the connection to optimize the reception effect of the signal.

[0052] The use of voltage stabilizing diodes D3 and D4 provides additional protection for the circuit, ensuring that it can still work stably under various external voltage fluctuations. The combination of resistors R31 and R32 allows triode Q3 to work stably, further enhancing the circuit's anti-interference ability.

[0053] The device is powered by a battery. In order to achieve the goal of low power consumption and effectively prolong the service life of the product, the Cat.1 module of the main control chip designs a flexible power management strategy. Specifically, the Cat.1 module can manage the working power of the redcap module through a control signal switch. This means that when the system does not need to detect 5G signals, the Cat.1 module can actively turn off the power of the redcap module to avoid unnecessary energy consumption.

[0054] In actual application, the main control chip Cat.1 module will intelligently judge whether it needs to activate the redcap module according to the current work demand. When the system is in standby state or has not received a monitoring task, the Cat.1 module will automatically enter a low-power sleep mode. In this mode, the core circuit of the chip will be turned off, and only a small amount of auxiliary circuit will remain running, so that it can quickly wake up when a new task comes. This design can reduce the overall power consumption of the system, so that the battery can maintain the normal operation of the device for a longer period of time.

[0055] The redcap module is used to scan and obtain new radio access technology (NR, New Radio) related working parameter information. These working parameter information is of great significance for optimizing network performance, formulating network planning and maintenance. The high sensitivity and fast response capability of the redcap module enable it to effectively capture the characteristics of NR signals in various environments, thereby providing detailed working parameter data, including frequency configuration, channel bandwidth, power setting and other key parameters.

[0056] At the same time, the task of signal detection is realized by the Cat.1 module (Cat.1 module). The Cat.1 module has strong signal processing capability and can effectively scan the LTE (Long Term Evolution) related working parameter information. Through the detection of LTE signals, the Cat.1 module can obtain important parameters including cell ID, frequency band, signal strength and quality.

[0057] In actual operation, the cooperation of redcap module and Cat.1 module provides a solution for signal monitoring. Redcap module focuses on scanning and analyzing NR signal to ensure that the latest network parameters can be captured in time, while Cat.1 module is responsible for detecting LTE signal to ensure that users can obtain stable connection in different network environments. The design of dual-mode work not only improves the efficiency of signal detection, but also enhances the adaptability of the system to different network technologies.

We explicitly point out that any reasonable modification, equivalent replacement or technical improvement under the guidance of the spirit and principle of the utility model should be included in the protection scope of the utility model. This means that as long as these changes do not deviate from the core idea and basic function of the invention, they should be protected by the patent right. The protection scope of the utility model should be extensive, including all direct obvious variants and non-obvious innovations that can be reasonably deduced by technical experts according to the disclosure of the utility model.
