[0017] First, the terms involved in one or more embodiments of the present application are explained.

[0018] The RS232 protocol is a standard protocol for serial communication, designed to solve the standardization problem of communication between computers and external devices (such as modems, printers, etc.).

[0019] RS232 is a traditional serial communication standard protocol widely used for data transmission between computers and external devices. With the advancement of electronic technology, RS232 communication has become widely used in industrial control, data transmission, and other fields. Advances in signal processing technologies, such as digital filtering, synchronous detection, and noise suppression algorithms, have become key. Key technologies include noise suppression filters (such as linear filters and nonlinear filters), adaptive equalizers, and noise source location and suppression strategies.

[0020] Key technologies in RS232 communication noise suppression algorithms include noise suppression filters (such as current filters and nonlinear filters), adaptive equalizers, and noise source location and suppression strategies. In noise suppression algorithms, a combination of analog and digital filters is typically used to suppress noise and interference, but this approach has limited effectiveness, especially in complex environments. Alternatively, fixed filter parameters are used to adapt to specific noise environments, but this approach is unable to adapt to diverse noise environments and exhibits unstable performance. Alternatively, simple signal processing algorithms, such as mean and median filters, are used, but these algorithms struggle to meet the demands of high-precision and high-speed communication.

[0021] Based on this, in the present application, a noise suppression method is provided. The present application also relates to a noise suppression device, a computing device, a computer-readable storage medium and a computer program product, which are described in detail one by one in the following embodiments.

[0022] Figure 1 A flowchart of a noise suppression method according to an embodiment of the present application is shown, which specifically includes the following steps: Step 102: Acquire initial signal information received by the target chip.

[0023] The target chip can be understood as an RS232 chip, a crucial component in implementing the RS232 protocol. It's widely used in computers, communications equipment, industrial control, and other fields for serial communication between devices. The RS232 chip uses serial communication to transmit data. The transmitter converts parallel data into serial data, which is then transmitted via a connected transmission line to the receiver, which then converts the serial data back into parallel data. This process involves digital signal processing and analog signal processing techniques in electronics. The RS232 chip uses a series of conventions to represent a frame of data, including a start bit, data bits, parity bits, and stop bits. The combination of these bits determines the data format and communication accuracy.

[0024] Initial signal information can be understood as the signal information generated by the target chip during business data communication. In the method provided in the embodiment of the present application, initial signal information can be understood as the signal information actually collected by the target chip. The initial signal information may contain signal noise due to problems such as transmission distance, electromagnetic interference, poor grounding, signal crosstalk, and signal attenuation. The noise suppression method provided in the embodiment of the present application can suppress and eliminate the signal noise in the received initial signal information, thereby restoring the true signal information.

[0025] In a specific embodiment provided in the present application, obtaining initial signal information received by the target chip includes: Target point voltage information received by the target chip at multiple target points is acquired.

[0026] In practice, RS232 uses negative logic levels, meaning -15V to -3V represents a logic "1," and +3V to +15V represents a logic "0." The voltage level here refers to the voltage of the TXD line (or RXD line) relative to GND. Therefore, in the methods provided in the embodiments of this application, obtaining the initial signal information of the target chip actually involves obtaining the target voltage information received by the target chip at multiple target points.

[0027] See also Figure 2 , Figure 2 : is a waveform diagram of the initial signal information provided by an embodiment of the present application. Figure 2 As shown in the figure, the initial signal information received includes 7 target points. The target point voltage information corresponding to each target point is shown in the figure. +3V~+15V represents logic "0", and -15V~-3V represents logic "1". The signal information sent by the external device is "10000000", but due to the noise in the transmission process, the voltage information received by the target chip will fluctuate, that is, Figure 2The waveform diagram is shown. For example, the voltage information corresponding to the target point "1" is -13V, and the voltage information corresponding to the target point "0" is 2V. At this time, the voltage of some target points is outside the zero threshold voltage. Therefore, the system cannot obtain the actual logic information of the target points outside the zero threshold voltage. It is necessary to denoise the target voltage information received from each target point.

[0028] In a specific embodiment provided in the present application, obtaining initial signal information received by the target chip includes: The target chip sends an information processing instruction to the target external device, and obtains initial signal information returned by the target external device in response to the information processing instruction; Accordingly, the method further includes: Acquire expected signal information corresponding to the information processing instruction.

[0029] In actual applications, before the target chip receives the initial signal information, it will first send an information processing instruction to the target external device. After receiving the information processing instruction, the target external device will feed back the corresponding initial signal information to the target chip.

[0030] Similarly, when the target chip sends an information processing instruction, it also has the expected signal information corresponding to that instruction. This means that when the target chip issues an information processing instruction, it knows in advance what information the external device will return in response to that instruction. This expected signal information can be used later to compare the initial signal information and adjust the reference point voltage information for noise suppression.

[0031] Step 104: removing noise information from the initial signal information according to the reference point voltage information and the preset signal voltage range to obtain target signal information.

[0032] In the method provided in the embodiments of the present application, noise information in the initial signal is removed and suppressed based on reference point voltage information and a preset signal voltage range. The reference point voltage information can be understood as judgment information used to determine the logical value of the target point. The preset signal voltage range is the voltage range corresponding to the logical value in the RS232 signal transmission rules. That is, -15V to -3V represents a logical "1", and +3V to +15V represents a logical "0".

[0033] The reference point voltage information and the preset signal voltage range can be used to remove noise information from the initial signal information, thereby obtaining the true target signal information. The target signal information can be understood as the true signal information transmitted by the RS232 protocol, which does not include signal noise.

[0034] In a specific embodiment provided in the present application, removing noise information from the initial signal information according to the reference point voltage information and the preset signal voltage range to obtain target signal information includes: Determining a target point to be processed and voltage information of the target point to be processed corresponding to the target point to be processed, wherein the target point to be processed is any one of the target points; Determining whether the voltage information of the target point to be processed is within the preset signal voltage range; If yes, determining the target point signal information corresponding to the target point to be processed according to the preset signal voltage interval; If not, determining the target point signal information corresponding to the target point to be processed according to the reference point voltage information and the voltage information of the target point to be processed; Target signal information is generated according to the target point signal information corresponding to each target point.

[0035] The initial signal information includes multiple target points. In a specific implementation provided in the present application, the target point to be processed is taken as an example for explanation. The target point to be processed is any one of the target points.

[0036] Because the initial signal contains noise, it affects the voltage information of the target point to be processed. Different noise levels produce different voltage information at the target point to be processed. Therefore, we must make judgments based on the voltage information of the target point to be processed. The voltage information of the target point to be processed is the voltage information of the target point to be processed in the initial signal information. This is the voltage information actually collected by the target chip at the target point to be processed.

[0037] First, determine whether the voltage information of the target point to be processed is still within the preset signal voltage range. If so, it means that the target point to be processed is not significantly affected by the noise and its logic value is not significantly affected. Then, the target point signal information corresponding to the target point to be processed can be directly determined according to the logic value corresponding to the preset signal voltage range.

[0038] If the voltage information of the target point to be processed has exceeded the preset signal voltage range, it means that the target point to be processed is greatly affected by noise and has exceeded the preset signal voltage range. In order to better judge the signal information of the target point to be processed, it is necessary to introduce the reference point voltage information for judgment, and further judge the target point signal information corresponding to the target point to be processed through the reference point voltage information.

[0039] After the target point signal information corresponding to each target point is determined, the target point signal information corresponding to each target point can be spliced ​​and combined to generate target signal information.

[0040] In another specific embodiment provided in the present application, the preset signal voltage interval includes a first voltage interval and a second voltage interval; Determining target point signal information corresponding to the target point to be processed according to the preset signal voltage interval includes: When the voltage information of the target point to be processed is within the first voltage interval, determining the target point signal information corresponding to the target point to be processed as a first voltage signal; In a case where the voltage information of the target point to be processed is within the second voltage interval, the target point signal information corresponding to the target point to be processed is determined to be a second voltage signal.

[0041] As described in the above embodiment, RS232 uses a negative logic level, that is, -15V~-3V represents a logic "1", and +3V~+15V represents a logic "0". Therefore, the preset signal voltage range is further divided into a first voltage range and a second voltage range, wherein +3V~+15V can be understood as the first voltage range, and -15V~-3V can be understood as the second voltage range. If the target point voltage information of the target point to be processed is within the first voltage range, then the target point signal information corresponding to the target point to be processed can be determined to be 0; if the target point voltage information of the target point to be processed is within the second voltage range, then the target point signal information corresponding to the target point to be processed can be determined to be 1. The first voltage signal can be understood as a logic value "0", and the second voltage information can be understood as a logic value "1".

[0042] In practical applications, if the influence of noise is large, the voltage information of the target point to be processed may not be within the first voltage interval or the second voltage interval. In this case, further judgment can be made based on the reference voltage information.

[0043] In another specific embodiment provided in the present application, the reference point voltage information is used to distinguish the first voltage signal from the second voltage signal; Determining target point signal information corresponding to the target point to be processed according to the reference point voltage information and the voltage information of the target point to be processed, including: In a case where the voltage information of the target point to be processed is greater than the voltage information of the reference point, determining that the target point signal information corresponding to the target point to be processed is a first voltage signal; In a case where the voltage information of the target point to be processed is less than the voltage information of the reference point, determining that the target point signal information corresponding to the target point to be processed is a second voltage signal; In a case where the voltage information of the target point to be processed is equal to the voltage information of the reference point, the target point signal information is determined according to a trend of the voltage information corresponding to the target point to be processed.

[0044] The reference point voltage information is a voltage value used to distinguish whether the target point signal information of the target point to be processed belongs to the first voltage signal or the second voltage signal. The first voltage signal can be understood as a logic value "0" and the second voltage information can be understood as a logic value "1".

[0045] If the target point voltage is greater than the reference point voltage, the target point signal corresponding to the target point is determined to be a first voltage signal, i.e., a logical value of "0." If the target point voltage is less than the reference point voltage, the target point signal corresponding to the target point is determined to be a second voltage signal, i.e., a logical value of "1." If the voltage information of the target point to be processed is equal to the voltage information of the reference point, the target point signal information corresponding to the target point to be processed cannot be simply determined as "0" or "1". Instead, the corresponding target signal information must be determined based on the trend of the voltage information corresponding to the target point to be processed. If the voltage information trend corresponding to the target point to be processed is greater than the reference point voltage information, the target point signal information of the target point to be processed is determined to be the first voltage signal; if the voltage information trend corresponding to the target point to be processed is less than the reference point voltage information, the target point signal information of the target point to be processed is determined to be the second voltage signal.

[0046] In a specific embodiment provided in the present application, the target point signal information includes a first voltage signal or a second voltage signal; Generate target signal information based on target point signal information corresponding to each target point, including: Target signal information is generated according to the first voltage signal or the second voltage signal corresponding to each target point.

[0047] After the above processing, the target point signal information corresponding to each target point can be determined. Specifically, the target signal point information corresponding to each target point can be determined to be a logical value of "0" (first voltage signal) or a logical value of "1" (second voltage signal). Furthermore, the target signal information can be determined based on the target signal point information corresponding to each target point.

[0048] See also Figure 3 , Figure 3 FIG. 1 shows a waveform diagram of target signal information provided by an embodiment of the present application, such as Figure 3 As shown in Figure 3 The voltage waveform is shown.

[0049] Step 106: parse the target signal information to obtain a signal recognition result corresponding to the target signal information.

[0050] Once the target signal information is obtained, the target signal information can be parsed to obtain a signal recognition result corresponding to the target signal information. The signal recognition result can be understood as information sent to the target chip by the external device after parsing the target signal information.

[0051] In a specific embodiment provided in the present application, parsing the target signal information to obtain a signal recognition result corresponding to the target signal information includes: converting the target signal information into logic level information, and sending the logic level information to a processor; The logic level information is parsed in the processor to obtain a signal recognition result corresponding to the logic level information.

[0052] In the method provided in the embodiments of the present application, after obtaining the target signal information, i.e., the signal voltage information, it is necessary to perform level conversion to convert the target signal information into logic level information. Specifically, the RS232 level is converted to TTL level, where TTL specifically refers to transistor transistor logic (TTL). TTL level signals specify that +5V is equivalent to a logic "1" and 0V is equivalent to a logic "0" (when using binary to represent data). This data communication and level specification method is called the TTL (transistor-transistor logic) signal system. This is the standard technology for communication between various components within a device controlled by a computer processor. Common electronic devices mostly use TTL levels, but their drive capability and anti-interference capabilities are very poor, making them unsuitable as external communication standards. Some communication methods, such as RS232, RS485, and USB, do not use TTL levels on their transmission lines. Therefore, the signals on these communication lines must undergo level conversion on the electronic device side for normal communication.

[0053] RS232 is commonly used for serial communication between computers and external devices. It transmits data over relatively long distances but at a relatively slow rate. TTL (Telescopic Transistor) levels are widely used in various digital circuits, microcontrollers, logic chips, and communication interfaces, and are suitable for short-distance, low-power, and logic-based communication. RS232 has a higher voltage, and connecting directly to a TTL-level device could damage the interface circuit chip. Converting RS232 levels to TTL levels is also necessary to meet the data communication needs between different devices.

[0054] After converting the RS232 level to the TTL level, the TTL level is input into the processor (CPU), and the CPU further processes the logic level information to obtain a signal recognition result corresponding to the logic level information.

[0055] Step 108: Compare the signal recognition result with the expected signal information, and adjust the reference point voltage information according to the comparison result.

[0056] After obtaining the signal recognition results, the data can be compared between the signal recognition results and the expected signal information to determine whether the signal recognition structure obtained by analysis meets the expectations. The reference point voltage information can be further adjusted based on the comparison results.

[0057] In practical applications, signal recognition results are de-noised using reference point voltage information. If the reference point voltage information is not properly set during the initial de-noising process, the de-noising process may be inaccurate. Therefore, the signal recognition results must be compared with the expected signal information, and the reference point voltage information can be further adjusted based on the comparison results.

[0058] In a specific embodiment provided in the present application, comparing the signal recognition result with the expected signal information, and adjusting the reference point voltage information according to the comparison result, includes: Determine whether there is an abnormal target point based on the signal recognition result and expected signal information; In the case where an abnormal target point exists, the reference point voltage information is adjusted according to the signal recognition result corresponding to the abnormal target point and the expected signal information.

[0059] In practical applications, the signal recognition results are compared with the expected signal information. Specifically, this can be understood as determining whether there are any abnormal target points in the signal recognition results. If there are abnormal target points, it indicates that the denoising process for these abnormal points has failed, and the reference point voltage information needs to be adjusted based on the signal recognition results and the expected signal information.

[0060] For example, if the signal recognition result of a target abnormal point is 0, and its expected signal information is 1, it means that the reference point voltage information is set too high. The reference point voltage information needs to be lowered so that the signal recognition result of the target abnormal point can be identified as 1, thereby improving the accuracy of noise removal.

[0061] In another specific embodiment provided in this application, the method further includes: detecting signal voltage information received by the target chip; When the signal voltage information is outside the preset signal voltage range, the preset signal voltage range is adjusted according to the signal voltage information.

[0062] In this embodiment, the target chip also detects the received signal voltage information in real time. If the received signal voltage information is outside the preset signal voltage range, the preset signal voltage range can be adjusted based on the signal voltage information. For example, if the preset signal voltage range is +15V to -15V and the received signal voltage information is 20V, the preset signal voltage range can be set to +20V to -20V based on the signal voltage information 20V. Specifically, the preset signal voltage range can be divided into +20V to +3V and -3V to -20V.

[0063] See also Figure 4 , Figure 4 FIG. 1 is a schematic diagram showing the signal flow of the noise suppression method provided by an embodiment of the present application. Figure 4 As shown, the external device sends a signal, which is sent to the signal processing circuit of the target chip through the RS232 signal receiving line. The signal processing circuit removes noise from the signal by voltage comparison and sends the signal after interference removal to the RS232 transceiver of the target chip. The RS232 level is converted to TTL level in the transceiver, and the TTL level is sent to the integrated core controller. The TTL level is analyzed in the integrated core controller, and the reference point voltage information in the signal processing circuit is adjusted according to the comparison result by comparing the data.

[0064] Through the method provided in the embodiment of the present application, the noise information in the initial signal information received by the target chip can be eliminated by comparison of the signal processing circuit, thereby obtaining the target signal information. Noise interference is eliminated to improve the reliability of communication. After parsing the target signal information, the recognition result and the expected signal information are compared, and the voltage in the signal processing circuit is adjusted according to the comparison result. Dynamically adjusting the voltage in the signal processing circuit can adapt to noise and interference in different environments and conditions, ensure data integrity and improve the accuracy of data transmission.
