[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Figure 1 It 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 (Power Management Integrated Circuit, PMIC) and a central processing unit (Center 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), such as 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 pre-emphasize the parameters of SerDes 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 SerDes based on the data transmission rate of 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 set by the central control host before leaving the factory, or may be 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 schematic diagram of the serial deserializer provided by the present invention. Figure 2 In the 1980s, the serializer is used to convert nbit parallel data into 1 / 2 lane high-speed serial data; PLL (Phase Locked Loop) is a phase-locked loop used for clock frequency division; Code is an encoder used to encode high-speed serial data; FFE (Feed Forward Equalization) is a feedforward equalizer, that is, a pre-emphasis equalizer, which compensates for the high-frequency components of the encoded transmission data in order to compensate for the attenuation during transmission; HSD (High Speed ​​Data) transmission harness is a high-speed data transmission harness used to connect the transmitter and the receiver for data transmission; CTLE (Continuous-Time Linear Equalization) is a continuous-time linear equalizer, which is equivalent to an amplifier + high-pass filter; DFE (Decision Feedback Equalizer) is a decision feedback equalizer, which is a digital equalizer used to eliminate crosstalk (Inter-Symbol Interference, ISI) during data transmission, that is, inter-symbol interference; Decode is a decoder used to decode high-speed serial data and restore the source code; CDR (Clock Data 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, and can also increase the number of handshakes and retry mechanisms to improve the success rate of link establishment.

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

[0046] In the process of determining the compensation result, if the data transmission rate of SerDes is greater than or equal to the preset threshold (such as 5Gbps), it means that the data transmission rate is relatively high at this time, 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 (such as CTLE and DFE) in the receiving end, and perform pre-emphasis parameter compensation on the transmitter to obtain the compensation result; if the data transmission rate is less than the preset threshold (such as 5Gbps), it means that the data transmission rate is relatively low at this time. 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 the compensation result. In the whole process, the signal transmission quality of SerDes can be effectively improved, so that a stable SerDes signal link can be established, effectively solving the problems of asynchronous serializer and deserializer signals, signal attenuation, and signal miscellaneous 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 It can be seen that the central control host adjusts the impedance (i.e., transmission impedance) of the HSD transmission harness through the common-mode inductance of the transmitter and the matching resistance of the receiver. Specifically, the transmission impedance can be reduced to obtain the target impedance to reduce the signal reflection, ringing, and jitter caused by impedance mismatch and suppress common-mode interference. In other words, by reducing the transmission impedance, the current driving capability of the transmitter can be improved and the signal attenuation caused by long-distance signal transmission can be reduced. The shielding effect of the HSD transmission harness can also be enhanced 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 domain control voltage of the PMIC and the operating main frequency of the CPU, the following tasks can be completed in advance: 1. Determination of the hardware design stage, such as power demand analysis and PMIC selection; 2. Interface design between PMIC and CPU, such as interface definition and signal transmission; 3. Development of voltage management strategy, such as the relationship between voltage and frequency and dynamic voltage scaling (Dynamic Voltage Scaling, DVS).

[0051] It should be noted that SOC (System On Chip) is a system-level chip unit, which is a combination of system-level software and hardware. In the original design of SOC, considering the relationship between the frequency, voltage and power consumption of the device, some domains are allowed to run at lower frequencies and voltages, while other domains run at higher voltages and frequencies. According to the internal chip design principles of SOC, the domain control voltage of PMIC and the working main frequency of CPU need to follow a strict one-to-one mapping relationship.

[0052] Any inconsistency in the matching relationship may cause instability in the screen-machine separation system, resulting in black screen and downtime. Therefore, the central control host can map the domain control voltage of the PMIC and the working main frequency of the CPU to obtain the mapping result. In this way, a stable synchronization relationship can be established between the domain control voltage of the PMIC and the working main frequency of the CPU, which helps to improve the stability of the screen-machine 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 It can be seen that the domain control voltage of PMIC can include multiple sub-domain control voltages. Assuming there are n+1 sub-domain control voltages, it can be expressed as: Volt_0, Volt_1, Volt_2, ..., Volt_n; the working main frequency of CPU can include multiple sub-working main frequencies. Assuming there are n+1 sub-working main frequencies, it can be expressed as: Cpu_0, Cpu_1, Cpu_2, ..., Cpu_n; the task requirement information can include multiple sub-requirement information. Assuming there are n+1 sub-requirement information, it can be expressed as: Task_0, Task_1, Task_2, ..., Task_n. The central control host can map the n+1 sub-domain control voltages, n+1 sub-working main frequencies and n+1 sub-requirement information one by one to obtain the 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 signal of the display module to obtain a synchronization result 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 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] Since the black screen phenomenon in the existing screen-machine separation system may be caused by the occasional drop of the display screen in the display module or the occasional drop of the HSD transmission signal, the traditional serial setting is changed, and the central control host dynamically polls and monitors the SerDes to obtain the monitoring results. In this way, the black screen phenomenon in the screen-machine separation system can be effectively avoided, which helps to improve the stability of the screen-machine separation system.

[0062] In some embodiments, the receiving end may include a deserializer; the central control host dynamically polls and monitors the SerDes to obtain monitoring results, 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 duration 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 duration to obtain a monitoring result; when the reading result indicates a read failure, the central control host initializes the SerDes and performs a delay operation according to a preset duration 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 monitoring.

[0065] The following operations are performed for any polling monitoring: 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 that the reading is successful, 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 that the link is successful, 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 time (such as 3s) to obtain the monitoring result; if the link result indicates that the link fails, 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 time to obtain the monitoring result; if the reading result indicates that the reading fails, 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 time 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 black screen and downtime in the screen-machine separation system, and enhance the operator's operating experience.

[0068] In some embodiments, the method may also 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 for 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 requirement information and the load information of the screen-machine separation system, and then determine the core voltage value required by the CPU at the 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 operating frequency of the CPU, to obtain a fixed-frequency output result. It can improve the stability of the screen-machine 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 compensation results; the domain control voltage of PMIC and the working main frequency of CPU are mapped to obtain mapping results; the touch signal of the display module is calibrated and synchronized to obtain synchronization results; SerDes is dynamically polled and monitored to obtain monitoring results; and the stability optimization results corresponding to the screen-machine separation system are determined according to the compensation results, mapping results, synchronization results and monitoring results. This method comprehensively considers the compensation results, mapping results, synchronization results and monitoring results to determine the stability optimization results corresponding to the screen-machine separation system, which can effectively improve the stability of the system, avoid the black screen and downtime phenomenon of the screen-machine separation system, and improve the operating experience of the operator.

[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 The central control host provided by the present invention is a schematic diagram of the structure of the central control host, which 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 via 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 used 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 working 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 monitoring results.

[0082] The CPU is used to determine the 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 of the third component module 503 are: first establish the screen-machine separation SerDes link layer (the first framework layer), if the establishment is completed, then build the Touch Panel touch input subsystem (the second framework layer), if the construction is completed, then set the system environment of the Linux GUI subsystem (the third framework layer), so far, the construction of the third component module 503 is completed. It should be noted that the above three framework layers are information-synchronous, not discrete.

[0085] Optionally, the SerDes may include: a transmitting end and a receiving end; a first component module 501, which is 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 value; and to perform pre-emphasis parameter compensation on the receiving end based on preset parameters to obtain the compensation result when the data transmission rate is less than the preset threshold value.

[0086] Optionally, the receiving end may include a deserializer; a fourth component module 504 is specifically used to determine a reading result corresponding to a status bit of the deserializer; when the reading result indicates a successful read, determine a 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 a 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 realize 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 supply isolation technologies such as transformers or optical coupler isolation can also be used to reduce the impact of power supply noise on the circuit. The power supply circuit and signal line of the screen-machine separation system can also be grounded to eliminate potential potential differences and grounding currents to eliminate interference with electronic devices.
