[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0052] The components of the embodiments of this application described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0053] Furthermore, the flowcharts used in this application illustrate operations implemented according to some embodiments of this application. It should be understood that the operations in the flowcharts may not be implemented in sequence, and steps without logical contextual relationships may be reversed in order or performed simultaneously. Moreover, those skilled in the art, guided by the content of this application, may add one or more other operations to the flowcharts, or remove one or more operations from the flowcharts.

[0054] The following explanation, in conjunction with several specific application examples, illustrates a high-frequency digital signal monitoring method provided in the embodiments of this application. Figure 1 A flowchart illustrating a high-frequency digital signal monitoring method according to an embodiment of this application is shown below. Figure 1 As shown, the method includes:

[0055] S101: Obtain the high-frequency feedback signal of the high-frequency unit.

[0056] In the embodiments of this application, the high-frequency digital signal monitoring method can be applied to scenarios involving the processing of high-frequency signals, such as monitoring the laser function of a car to determine whether the car's laser is operating at a fixed preset safety frequency. In addition, it can also be applied to safety monitoring scenarios for high-frequency scenarios. The specific application scenarios can be flexibly adjusted according to user needs and are not limited to those given in the above embodiments.

[0057] Figure 2 This is a schematic diagram of the structure of a monitoring system provided in an embodiment of this application, as shown below. Figure 2 The monitoring system 300 includes a processor 301 and a high-frequency unit 302. The high-frequency unit may include, for example, a transmitter driver 3021 and a high-frequency digital / analog signal processing unit 3022. After receiving a control signal for the high-frequency unit 302 sent by the processor 301, the transmitter driver 3021 drives the high-frequency transmitter to send a high-frequency signal to the high-frequency digital / analog signal processing unit 3022 based on the control signal. The high-frequency digital / analog signal processing unit 3022 processes the high-frequency signal to obtain a high-frequency feedback signal and sends the high-frequency feedback signal to the processor 301 so that the processor 301 can determine whether there is a fault in the working state of the high-frequency unit 302 based on the high-frequency feedback signal.

[0058] S102: Buffer the high-frequency feedback signal of the high-frequency unit.

[0059] The processor in this embodiment is a microprocessor. Since the computing performance of a microprocessor is limited, if the high-frequency feedback signal of the high-frequency unit is directly input into the microprocessor, it may cause the microprocessor to be unable to process it properly because the feedback frequency of the high-frequency feedback signal is too high. Therefore, in this embodiment, the microprocessor buffers the high-frequency feedback signal sent by the high-frequency unit into a preset buffer of the microprocessor.

[0060] S103: If the high-frequency feedback signal of the cached high-frequency unit meets the preset detection conditions, then the high-frequency unit is fault detected based on the high-frequency feedback signal of the cached high-frequency unit.

[0061] In the embodiments of this application, fault detection of the high-frequency unit is to perform real-time fault detection of the high-frequency unit. After determining that the high-frequency feedback signal of the cached high-frequency unit meets the preset detection conditions, the high-frequency unit is immediately subjected to real-time fault detection based on the high-frequency feedback signal of the cached high-frequency unit.

[0062] By buffering high-frequency feedback signals, the microprocessor can avoid processing each received high-frequency feedback signal individually, which would cause the microprocessor's processing speed to be slower than the reception speed, resulting in insufficient computing performance. Buffering high-frequency feedback signals allows them to be accumulated first. Once the accumulated high-frequency feedback signals meet the preset detection conditions, all accumulated high-frequency feedback signals are processed at once, which greatly reduces the processing frequency of the microprocessor when processing high-frequency feedback signals, thus ensuring the microprocessor's processing performance.

[0063] In some possible embodiments, the method for determining whether the high-frequency feedback signal meets the preset detection conditions may be, for example, determining whether the number of high-frequency feedback signals of the cached high-frequency units is equal to a preset number threshold; if it is equal, then determining that the high-frequency feedback signal of the cached high-frequency units meets the preset detection conditions.

[0064] Continue as Figure 2 As shown, the processor 301 also includes a preset cache area for caching the acquired high-frequency feedback signals.

[0065] For example, the microprocessor is pre-configured with a preset number threshold of any integer such as 32, 64, 128, or 256. When the number of high-frequency feedback signals cached in the preset cache area meets the preset number threshold, it is determined that the current cached high-frequency feedback signal meets the preset detection condition. Then, the microprocessor obtains all the current cached high-frequency feedback signals from the preset cache area and processes them.

[0066] In some other possible embodiments, the method for determining whether the high-frequency feedback signal meets the preset detection conditions may be, for example, determining whether the buffering time of the high-frequency feedback signal of the buffered high-frequency unit is equal to a preset time threshold; if it is equal, then determining that the high-frequency feedback signals of all buffered high-frequency units meet the preset detection conditions.

[0067] For example, the microprocessor is pre-configured with a preset time threshold of 1 second or 30 milliseconds, etc. The timing starts from the first high-frequency feedback signal cached in the preset buffer. If the timing time meets the preset time threshold, the current cached high-frequency feedback signal meets the preset detection condition. Then the microprocessor obtains all high-frequency feedback signals cached in the preset buffer within the timing time and processes them.

[0068] It should be understood that the values ​​of the preset quantity threshold and the preset time threshold mentioned above are merely illustrative examples. The specific settings of the preset quantity threshold and the preset time threshold can be flexibly adjusted according to the user's needs and are not limited to those given in the above embodiments.

[0069] The high-frequency digital signal monitoring method provided in this application allows the processor to directly acquire the high-frequency feedback signal from the high-frequency unit, cache the acquired high-frequency feedback signal, and perform fault detection on the high-frequency unit based on the cached high-frequency feedback signal after the cached high-frequency feedback signal meets the preset detection conditions. Since the processor is the only decision node in the monitoring system, this detection method reduces the number of decision nodes in the monitoring system, reduces the necessary time limits for decision-making, and reduces the difficulty of functional safety time limits due to its simple logical relationship, thus ensuring the stability and efficiency of the monitoring system.

[0070] In the embodiments of this application, the high-frequency feedback signal of the high-frequency unit can be obtained, for example, by using a preset high-speed serial protocol to obtain the high-frequency feedback signal of the high-frequency unit.

[0071] Continue as Figure 2As shown, the processor 301 may also include a preset high-speed serial interface, which includes at least one preset high-speed serial protocol for obtaining the high-frequency feedback signal of the high-frequency unit into a preset buffer according to the preset high-speed serial protocol. After the high-frequency feedback signal buffered in the preset buffer meets the preset detection conditions, the microprocessor obtains the high-frequency feedback signal in the preset buffer that meets the preset detection conditions for fault detection, so as to troubleshoot the high-frequency unit and determine whether the high-frequency unit has a fault.

[0072] In some possible embodiments, the preset high-speed serial protocol may include, but is not limited to: 安 Protocols such as Secure Digital Input and Output (SDIO), Universal Serial Bus (USB), EtherNet (ETH), Serial Peripheral Interface (SPI), Peripheral Component Interconnect Express (PCIE), Low-Voltage Differential Signaling (LVDS), and Mobile Industry Processor Interface (MIPI) are used for protocol conversion of high-frequency input signals.

[0073] Alternatively, in some other possible embodiments, the high-frequency feedback signal of the high-frequency unit can be obtained, for example, by obtaining the high-frequency feedback signal of the high-frequency unit based on a serial digital shift register.

[0074] For example, one end of the serial digital shift register is electrically connected to the high-frequency unit to receive the high-frequency feedback signal emitted by the high-frequency unit, and the other end is connected to the microprocessor to send the received high-frequency feedback signal to the microprocessor. After the serial digital shift register obtains the high-frequency feedback signal from the high-frequency unit, it registers the obtained high-frequency feedback signal. After the registered high-frequency feedback signal meets the preset detection conditions, it notifies the microprocessor to obtain the high-frequency feedback signal that meets the preset detection conditions from the registered high-frequency feedback signal for fault detection, so as to troubleshoot the high-frequency unit and determine whether the high-frequency unit has a fault.

[0075] In some possible embodiments, only one of the serial digital shift register and the preset buffer can be set, or both of the serial digital shift register and the preset buffer can be set in the monitoring system; the specific setting of the serial digital shift register and the preset buffer can be flexibly adjusted according to the user's needs and is not limited to the above embodiments.

[0076] Optionally, based on the above embodiments, this application embodiment can also provide a method for monitoring high-frequency digital signals. The implementation process of the above method will be illustrated below with reference to the accompanying drawings. Figure 3 A flowchart illustrating a high-frequency digital signal monitoring method according to another embodiment of this application is shown below. Figure 3 As shown, the method may further include:

[0077] S111: If a fault is detected in the high-frequency unit, the high-frequency unit is shut down to stop high-frequency signal processing.

[0078] For example, taking the application of laser function monitoring in automobiles as an example, if a malfunction is detected in the high-frequency laser unit of the automobile, the laser unit is controlled to shut down, that is, the laser unit is controlled to stop emitting laser signals.

[0079] In some other possible embodiments, after a fault is detected in the high-frequency unit, the fault information of the high-frequency unit can be sent to a preset maintenance device so that the preset maintenance device can perform corresponding processing or alarm based on the fault information.

[0080] For example, the preset maintenance equipment can be the car's main unit, such as the high-frequency unit, which can be the high beam unit. If a fault is detected in the high beam unit, the car's main unit can send a fault message to the main control screen to display and notify the user that the car's high beam unit is faulty, so that the user can troubleshoot the fault in time. If the user does not troubleshoot the fault within a preset time, the high beam unit will be turned off to stop the high beam signal processing and prevent the high beam emitted by the faulty high beam unit from affecting other pedestrians.

[0081] Optionally, based on the above embodiments, this application embodiment can also provide a method for monitoring high-frequency digital signals. The following is an example of the implementation process of fault detection of high-frequency units in the above method, with reference to the accompanying drawings. Figure 4 A flowchart illustrating a high-frequency digital signal monitoring method according to another embodiment of this application is shown below. Figure 4 As shown, S103 may include:

[0082] S121: Perform fault detection on the high-frequency feedback signal of the buffered high-frequency unit according to the preset signal format.

[0083] In the embodiments of this application, different high-frequency units may correspond to different fixed preset signal formats. For example, in some possible embodiments, when the high-frequency unit is a high-frequency laser unit, its corresponding preset signal format is, for example, "10, 10, ...". It should be understood that the above embodiments are only illustrative examples, and the specific preset signal format can be flexibly adjusted according to user needs. Different types of high-frequency units may correspond to different preset signal formats. The different preset signal formats corresponding to different types of high-frequency units are all pre-configured in the microprocessor. After the microprocessor obtains the high-frequency feedback signal, it will determine the corresponding preset signal format according to the type of high-frequency unit corresponding to the current high-frequency feedback signal, and then compare the preset signal format with the currently obtained high-frequency feedback signal to determine whether the signal format of the currently obtained high-frequency feedback signal is consistent with the preset signal format. If they are consistent, it is determined that the current high-frequency feedback signal is normal, that is, the current high-frequency unit is not faulty. If they are inconsistent, it is indicated that the current high-frequency feedback signal is abnormal, that is, the current high-frequency unit is faulty. For example, the preset signal format can also be "1100, 1100..." or "01, 01...", etc., and is not limited to the above embodiments.

[0084] S122: If at least one high-frequency feedback signal in the high-frequency feedback signal of the buffered high-frequency unit does not conform to the preset signal format, then it is determined that the high-frequency unit is faulty.

[0085] Taking the preset signal format "10, 10, ..." as an example, if the buffered high-frequency feedback signal is "10, 00, 10, 10, 10", and there is a "00" high-frequency feedback signal that does not conform to the preset signal format, it indicates that there is a fault in the current high-frequency unit.

[0086] The high-frequency digital signal monitoring method provided in this application uses only one decision node, the processor, in the monitoring system. The processor can directly acquire the high-frequency feedback signal from the high-frequency unit and cache it in a preset buffer. After the high-frequency feedback signal cached in the preset buffer meets the preset detection conditions, all high-frequency feedback signals in the preset buffer that meet the preset detection conditions are acquired. Based on the acquired high-frequency feedback signals, fault detection is performed on the high-frequency unit to determine whether a fault exists. If a fault exists, preset fault management is performed, such as stopping the high-frequency unit from working or reporting the fault. Since the monitoring sampling and decision-making nodes in the monitoring system are the same processor, this detection method reduces the number of decision-making nodes in the monitoring system, reduces the necessary limitations for decision-making, and reduces the difficulty of implementing functional safety due to its simple logical relationship, thus ensuring the stability and efficiency of the monitoring system.
