[0036] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] Figure 1 This is a flow chart of the stability optimization method for the screen-machine separation system provided by the present invention, which is applied to the central control host in the screen-machine separation system. The central control host may include: a power management integrated circuit (PMIC) and a central processing unit (CPU). The screen-machine separation system may also include a display module. The central control host interacts with the display module through a serial deserializer (SerDes) (short for serializer and deserializer). Figure 1 As shown, the method includes the following steps 101 to 105.

[0038] Step 101: Based on the data transmission rate of the SerDes, pre-emphasis parameter compensation is performed on the SerDes to obtain a compensation result.

[0039] The central control host can adopt a dynamic monitoring mechanism to change the traditional system silent settings, dynamically monitor the data transmission rate of SerDes, and compensate the SerDes pre-emphasis parameters based on the current data transmission rate to obtain compensation results to improve the signal transmission quality of SerDes, which helps to improve the stability of the screen-machine separation system.

[0040] In some embodiments, SerDes may include: a transmitting end and a receiving end; the central control host performs pre-emphasis parameter compensation on the SerDes based on the data transmission rate of the SerDes to obtain a compensation result, which may include: when the data transmission rate is greater than or equal to a preset threshold, the central control host performs pre-emphasis parameter compensation on the transmitting end based on the parameters of the target equalizer in the receiving end to obtain a compensation result; when the data transmission rate is less than the preset threshold, the central control host performs pre-emphasis parameter compensation on the receiving end based on the preset parameters to obtain a compensation result.

[0041] The preset threshold value may be factory-set by the central control host or user-defined. For example, the preset threshold value may be set to 5 Gbps (gigabits per second).

[0042] Exemplarily, the preset parameters may be standard eye diagram preset parameters.

[0043] For example, Figure 2 It is a structural diagram of the serial deserializer provided by the present invention. Figure 2 In the 1 / 2 lane high-speed serial data transmission, the serializer is used to convert n-bit parallel data into 1 / 2 lane high-speed serial data. The phase-locked loop (PLL) is a phase-locked loop used for clock frequency division. The code is an encoder used to encode high-speed serial data. The feed-forward equalizer (FFE) is a pre-emphasis equalizer that compensates for the high-frequency components of the encoded transmission data to compensate for attenuation during transmission. The HSD (High Speed ​​Data) transmission harness is a high-speed data transmission harness used to connect the transmitter and receiver for data transmission. The continuous-time linear equalizer (CTLE) is a continuous-time linear equalizer that acts like an amplifier + high-pass filter. The decision feedback equalizer (DFE) is a digital equalizer used to eliminate inter-symbol interference (ISI) during data transmission. The decoder is used to decode high-speed serial data and recover the source code. Recovery) refers to clock and data recovery; the deserializer is used to recover high-speed serial data into n-bit parallel data.

[0044] Optionally, the central control host can pre-unify the handshake protocol of the serializer and deserializer to avoid protocol mismatch problems. It can also increase the number of handshakes and retry mechanisms to improve the success rate of link establishment.

[0045] For example, combined Figure 2 , the above-mentioned target equalizer can be CTLE and DFE.

[0046] During the compensation process, if the SerDes data transmission rate is greater than or equal to a preset threshold (e.g., 5Gbps), indicating that the data transmission rate is high and errors may occur during signal transmission, the central control host can dynamically adjust the pre-emphasis parameters of the transmitter based on the parameters of the target equalizer (e.g., CTLE and DFE) at the receiver, and perform pre-emphasis parameter compensation on the transmitter to obtain a compensation result. If the data transmission rate is less than the preset threshold (e.g., 5Gbps), indicating that the data transmission rate is low, the central control host can dynamically adjust the pre-emphasis parameters of the receiver based on the preset parameters, and perform pre-emphasis parameter compensation on the receiver to obtain a compensation result. The entire process can effectively improve the signal transmission quality of the SerDes, thereby establishing a stable SerDes signal link and effectively resolving issues such as serializer and deserializer signal asynchrony, signal attenuation, and miscellaneous signal interference.

[0047] In some embodiments, SerDes may also include an HSD transmission harness, which is used to connect a transmitting end and a receiving end. The transmitting end may include a common-mode inductor, and the receiving end may include a matching resistor. The method may also include: the central control host adjusts the impedance of the HSD transmission harness through the common-mode inductor and the matching resistor to obtain the target impedance.

[0048] For example, Figure 3 Schematic diagram of the transmitting end and receiving end of the serial deserializer provided by the present invention. Figure 3 As can be seen in the figure, the central control host adjusts the impedance of the HSD transmission harness (i.e., the transmission impedance) through the common-mode inductor at the transmitter and the matching resistor at the receiver. Specifically, the transmission impedance can be reduced to the target impedance, thereby reducing signal reflections, ringing, and jitter caused by impedance mismatch and suppressing common-mode interference. In other words, by reducing the transmission impedance, the current driving capability of the transmitter can be improved, reducing signal attenuation caused by long-distance signal transmission. It can also enhance the shielding effect of the HSD transmission harness to reduce noise interference.

[0049] Step 102: Map the domain control voltage of the PMIC and the operating main frequency of the CPU to obtain a mapping result.

[0050] Optionally, before mapping the PMIC's domain-controlled voltage and the CPU's operating main frequency, the following tasks can be completed in advance: 1. Determination of the hardware design phase, such as power demand analysis and PMIC selection; 2. Interface design between the PMIC and the CPU, such as interface definition and signal transmission; 3. Development of voltage management strategies, such as the relationship between voltage and frequency and dynamic voltage scaling (DVS).

[0051] It's important to note that a System on Chip (SOC) is a system-on-chip unit, a system-level combination of hardware and software. The SOC's original design, taking into account the relationship between device operating frequency, voltage, and power consumption, allows some domains to operate at lower frequencies and voltages, while others operate at higher voltages and frequencies. According to SOC internal chip design principles, the PMIC's domain-controlled voltage and the CPU's operating frequency must maintain a strict one-to-one mapping.

[0052] Any inconsistency in the matching relationship can cause instability in the screen-to-computer separation system, resulting in black screen and system downtime. Therefore, the central control host can map the PMIC domain control voltage and the CPU operating frequency to obtain a mapping result. This can establish a stable synchronization relationship between the PMIC domain control voltage and the CPU operating frequency, helping to improve the stability of the screen-to-computer separation system.

[0053] Optionally, the central control host may also map the domain control voltage of the PMIC, the operating main frequency of the CPU, and the task requirement information to obtain a mapping result.

[0054] For example, Figure 4 It is a schematic diagram of the mapping result provided by the present invention. Figure 4 As can be seen from the figure, the PMIC's domain-controlled voltage can include multiple sub-domain-controlled voltages. Assuming there are n+1 sub-domain-controlled voltages, they can be represented as: Volt_0, Volt_1, Volt_2, ..., Volt_n. The CPU's operating frequency can include multiple sub-operating frequencies. Assuming there are n+1 sub-operating frequencies, they can be represented as: Cpu_0, Cpu_1, Cpu_2, ..., Cpu_n. Task requirement information can include multiple sub-requirement information. Assuming there are n+1 sub-requirement information, they can be represented as: Task_0, Task_1, Task_2, ..., Task_n. The central control host can perform a one-to-one mapping between the n+1 sub-domain-controlled voltages, the n+1 sub-operating frequencies, and the n+1 sub-requirement information to obtain a mapping result.

[0055] Step 103: calibrate and synchronize the touch signal of the display module to obtain a synchronization result.

[0056] The central control host can use real-time synchronization technology to calibrate and synchronize the touch signals of the display module to obtain synchronization results to ensure that when the operator touches the touch panel in the display module, the screen-machine separation system can accurately and quickly identify the touch signal and perform corresponding processing, which helps to improve the stability of the screen-machine separation system.

[0057] In some embodiments, the display module may include a touch screen (Touch Panel); the central control host calibrates and synchronizes the touch signal of the display module to obtain a synchronization result, which may include: the central control host calibrates and synchronizes the touch signal with the transmission signal of SerDes, the operating system of the central control host, and the calibration mechanism of the touch screen to obtain a synchronization result.

[0058] Exemplarily, the above-mentioned operating system may be a GUI subsystem of Linux.

[0059] The central control host can calibrate and synchronize the touch signal with the transmission signal of SerDes (such as HSD transmission signal), the operating system of the central control host (such as Linux GUI subsystem) and the adaptive calibration mechanism of the touch screen to obtain a synchronized touch signal, that is, a synchronization result.

[0060] Step 104: Perform dynamic polling monitoring on the SerDes to obtain monitoring results.

[0061] Because black screens in existing screen-to-machine separation systems can be caused by occasional drops in the display module or HSD transmission signals, the traditional serial setup has been changed to a central control host that dynamically polls the SerDes to obtain monitoring results. This effectively prevents black screens in screen-to-machine separation systems and helps improve their stability.

[0062] In some embodiments, the receiving end may include a deserializer; the central control host dynamically polls and monitors the SerDes to obtain a monitoring result, which may include: the central control host determines the reading result corresponding to the status bit of the deserializer; when the reading result indicates a successful read, the central control host determines the link result corresponding to the SerDes; when the link result indicates a successful link, the central control host performs a delay operation according to a preset time length to obtain a monitoring result; when the link result indicates a link failure, the central control host initializes the SerDes and performs a delay operation according to a preset time length to obtain a monitoring result; when the read result indicates a read failure, the central control host initializes the SerDes and performs a delay operation according to a preset time length to obtain a monitoring result.

[0063] The preset time length may be set by the central control host before leaving the factory or may be user-defined. For example, the preset time length may be set to 3 seconds (s).

[0064] It should be noted that, during the process of dynamic polling monitoring of SerDes, the central control host can perform multiple polling monitorings.

[0065] For any polling monitoring, the following operations are performed: the central control host first determines whether the status bit of the deserializer can be read, that is, determines the reading result corresponding to the status bit of the deserializer. If the reading result indicates a successful read, it means that the status bit of the deserializer can be read at this time. The central control host further determines whether the SerDes has established a valid link, that is, determines the link result corresponding to the SerDes. If the link result indicates a successful link, it means that the SerDes has established a valid link at this time. The central control host performs a delay operation according to the preset duration (such as 3s) to obtain the monitoring result; if the link result indicates a link failure, it means that the SerDes has not established a valid link at this time. The central control host reinitializes the SerDes and performs a delay operation according to the preset duration to obtain the monitoring result; if the read result indicates a read failure, it means that the status bit of the deserializer cannot be read at this time. The central control host reinitializes the SerDes and performs a delay operation according to the preset duration to obtain the monitoring result. This completes a polling monitoring process.

[0066] Step 105: Determine the stability optimization result corresponding to the screen-machine separation system according to the compensation result, mapping result, synchronization result and monitoring result.

[0067] After determining the compensation results, mapping results, synchronization results and monitoring results, the central control host can determine the stability optimization results corresponding to the screen-machine separation system based on these four results, which can effectively improve the system stability, avoid the black screen and downtime phenomenon of the screen-machine separation system, and enhance the operator's operating experience.

[0068] In some embodiments, the method may further include: the central control host determines the target operating frequency of the CPU based on task requirement information and load information of the screen-machine separation system; the central control host determines the core voltage value required by the CPU at the target operating frequency; the central control host adjusts the output voltage of the PMIC based on the characteristic parameters of the CPU, combined with the core voltage value and the preset operating frequency of the CPU, to obtain a fixed frequency output result.

[0069] Correspondingly, the central control host determines the stability optimization result corresponding to the screen-machine separation system based on the compensation result, mapping result, synchronization result and monitoring result, which may include: the central control host determines the compensation result, mapping result, synchronization result, monitoring result and fixed-frequency output result as the stability optimization result.

[0070] The target operating frequency refers to the specific operating frequency that the CPU needs to run in a specific working scenario indicated by the task requirement information and the load information of the screen-machine separation system.

[0071] Optionally, the characteristic parameters of the CPU may include specification parameters and performance parameters, etc.

[0072] Optionally, the preset operating frequency of the CPU may be set by the central control host according to a system firmware driver.

[0073] The central control host can determine the target operating frequency of the CPU based on the acquired task requirements and the load information of the screen-computer separation system, and then determine the core voltage value required by the CPU at this target operating frequency. The central control host can adjust the output voltage of the PMIC based on the acquired CPU characteristic parameters, combined with the core voltage value and the preset CPU operating frequency, to obtain a fixed-frequency output result. This can improve the stability of the screen-computer separation system in specific working scenarios.

[0074] In this way, the central control host can determine the compensation results, mapping results, synchronization results, monitoring results and fixed-frequency output results as stability optimization results.

[0075] In an embodiment of the present invention, based on the data transmission rate of SerDes, pre-emphasis parameter compensation is performed on SerDes to obtain a compensation result; the domain control voltage of the PMIC and the operating main frequency of the CPU are mapped to obtain a mapping result; the touch signal of the display module is calibrated and synchronized to obtain a synchronization result; the SerDes is dynamically polled and monitored to obtain a monitoring result; and the stability optimization result corresponding to the screen-machine separation system is determined based on the compensation result, mapping result, synchronization result, and monitoring result. This method comprehensively considers the compensation result, mapping result, synchronization result, and monitoring result to determine the stability optimization result corresponding to the screen-machine separation system, which can effectively improve system stability, avoid the black screen and downtime phenomenon of the screen-machine separation system, and enhance the operator's operating experience.

[0076] The central control host provided by the present invention is described below. The central control host described below and the stability optimization method for the screen-machine separation system described above can be referenced to each other.

[0077] Figure 5 This is a structural diagram of the central control host provided by the present invention. The central control host is arranged in the screen-machine separation system. Figure 5As shown, the central control host may include: an electronic management integrated circuit PMIC and a central processing unit CPU. The screen-machine separation system may also include a display module. The central control host interacts with the display module through a serial deserializer SerDes. The central control host may also include a first component module 501, a second component module 502, a third component module 503 and a fourth component module 504.

[0078] The first component module 501 is configured to perform pre-emphasis parameter compensation on the SerDes based on the data transmission rate of the SerDes to obtain a compensation result.

[0079] The second component module 502 is used to map the domain control voltage of the PMIC and the operating main frequency of the CPU to obtain a mapping result.

[0080] The third component module 503 is used to calibrate and synchronize the touch signal of the display module to obtain a synchronization result.

[0081] The fourth component module 504 is used to perform dynamic polling monitoring on the SerDes to obtain a monitoring result.

[0082] The CPU is configured to determine a stability optimization result corresponding to the screen-machine separation system according to the compensation result, the mapping result, the synchronization result, and the monitoring result.

[0083] For example, Figure 6 It is a schematic diagram of an application scenario of the central control host provided by the present invention. Figure 6 In the text, STQ cable refers to STQ cable; LCD (Liquid Crystal Display) refers to liquid crystal display. Figure 6 It can be seen that the central control host interacts with the display module through the serial deserializer SerDes.

[0084] Exemplarily, the construction steps for the third component module 503 are as follows: first, establish the screen-to-machine separation SerDes link layer (the first framework layer). If established, then build the touch panel input subsystem (the second framework layer). If established, then set the system environment of the Linux GUI subsystem (the third framework layer). This completes the construction of the third component module 503. It should be noted that the three framework layers are synchronized, not discrete.

[0085] Optionally, the SerDes may include: a transmitting end and a receiving end; a first component module 501, specifically used to perform pre-emphasis parameter compensation on the transmitting end based on the parameters of the target equalizer in the receiving end to obtain the compensation result when the data transmission rate is greater than or equal to a preset threshold; and to perform pre-emphasis parameter compensation on the receiving end based on the preset parameters to obtain the compensation result when the data transmission rate is less than the preset threshold.

[0086] Optionally, the receiving end may include a deserializer; a fourth component module 504 is specifically used to determine a reading result corresponding to the status bit of the deserializer; when the reading result indicates a successful reading, determine the link result corresponding to the SerDes; when the link result indicates a successful link, perform a delay operation according to a preset time length to obtain the monitoring result; when the link result indicates a link failure, initialize the SerDes, and perform a delay operation according to the preset time length to obtain the monitoring result; when the read result indicates a read failure, initialize the SerDes, and perform a delay operation according to the preset time length to obtain the monitoring result.

[0087] Optionally, the SerDes may also include an HSD transmission harness, which is used to connect the transmitting end and the receiving end. The transmitting end may include a common-mode inductor, and the receiving end may include a matching resistor. The fourth component module 504 is also used to adjust the impedance of the HSD transmission harness through the common-mode inductor and the matching resistor to obtain the target impedance.

[0088] Optionally, the display module may include a touch screen; the third component module 503 is specifically used to calibrate and synchronize the touch signal with the transmission signal of the SerDes, the operating system of the central control host and the calibration mechanism of the touch screen to obtain the synchronization result.

[0090] It should be noted that the central control host can support the SerDes hot-swap mechanism and implement dynamic monitoring of the screen-machine separation system in parallel. In addition, electronic filters can be added to the key circuits of the screen-machine separation system to remove interference signals of different frequencies and improve the signal-to-noise ratio. Filter circuits can also be added to the screen-machine separation system to eliminate high-frequency noise and clutter in the power supply. Power isolation technologies such as transformers or optical couplers can also be used to reduce the impact of power supply noise on the circuit. The power supply circuit and signal lines of the screen-machine separation system can also be grounded to eliminate potential potential differences and ground currents, thereby eliminating interference with electronic components.

The central control host includes: an electronic management integrated circuit PMIC and a central processing unit CPU. The screen-machine separation system also includes a display module. The central control host interacts with the display module through a serial deserializer SerDes.
