[0050] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The detection result determination method provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown. Among them, the display module 102 can communicate with the signal generator 104 through a bus, a port, a wireless local area network, etc. The signal generator 104 can communicate with the host computer 106 through a bus.

[0052] Specifically, the programmable logic device 1042 in the signal generator 104 can receive the interactive feedback signal sent by the display module 102. The programmable logic device 1042 in the signal generator 104 processes the interactive feedback signal, and determines the current interactive state of the signal generator 104 and the display module 102 according to the signal value of the interactive feedback signal. The programmable logic device 1042 in the signal generator 104 judges the current interactive state. When it is determined that the current interactive state is a fault state, an adjustment strategy corresponding to the current interactive state is obtained and executed to adjust the signal generator 104, and an adjustment result for the signal generator 104 is generated. The programmable logic device 1042 in the signal generator 104 generates the current detection result for the signal generator 104 according to the current interactive state and the adjustment result, and sends the detection result to the host computer 106 through the bus for display to the user in the host computer 106.

[0053] Among them, the display module 102 can but is not limited to be sourced from various personal computers, laptops, smartphones, tablets, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart TVs, in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. A programmable logic device 1042 can be deployed in the display module 104 to implement corresponding logical operation functions by using the programmable logic device 1042. The programmable logic device 1042 can include but is not limited to any one or more of a variety of logic devices such as a Field Programmable Gate Array (FPGA), a Programmable Array Logic (PAL), or a Generic Array Logic (GAL). The host computer 106 can directly interact with the user.

[0054] In one embodiment, as Figure 2 shown, a method for determining a detection result is provided. Taking the signal generator 104 in Figure 1 as an example for illustration, it includes the following steps:

[0055] Step S202, receive the interactive feedback signal of the display module to the signal generator.

[0056] Among them, the display module can include but is not limited to a liquid crystal display screen and a backlight component, and can be used to display image data. In one example, the display module can be a large-size, high-resolution, high-refresh-rate module composed of multiple groups of liquid crystal display screens and backlight components.

[0057] An independent programmable logic device can be deployed in the signal generator so that the signal generator can implement corresponding control, judgment, calculation, and other logical operation functions by using the programmable logic device.

[0058] Specifically, the programmable logic device in the signal generator can be used to receive the image data sent by the host computer, perform timing processing on the image data, and convert the image data into corresponding image timing signals. Pack and encode the image timing signals according to the high-definition digital display transmission protocol (such as the vbyone protocol), and perform preprocessing operations such as adding scrambling codes. Use the programmable logic device to perform parallel-to-serial conversion processing on the preprocessed image timing signals in the physical layer of the signal generator, and output serial image timing signals to the display module for dot screen. Use the programmable logic device to monitor the interactive signals between the display module and the signal generator in real time, and receive the interactive feedback signal fed back by the display module at the receiving end of the signal generator.

[0059] Step S204: Determine the interaction status between the display module and the signal generator according to the interaction feedback signal.

[0060] Among them, the interaction status may include, but is not limited to, any one of multiple statuses such as the unconnected status, the clock unlocked status, the training unlocked status, and the normal status.

[0061] Specifically, a mapping relationship between the signal value and the interaction status can be stored in the signal generator. The signal transmitter can obtain the signal value of the interaction feedback signal. The programmable logic device is used to classify the interaction status between the display module and the signal generator according to the signal value, and determine the interaction status matching the current signal value from the mapping relationship.

[0062] Step S206: In response to the judgment result that the interaction status is a fault status, execute the adjustment strategy corresponding to the fault status to adjust the signal generator and generate an adjustment result for the signal generator.

[0063] Specifically, an adjustment strategy corresponding to the fault status can be stored in the signal generator. When the interaction status determined by the signal generator is not the normal status, the programmable logic device can be used to obtain the adjustment strategy corresponding to the current fault status in response to the judgment result that the interaction status is a fault status, adjust the faulty module in the signal generator, record the adjustment parameters in the adjustment strategy and the status information of the adjusted faulty module, and generate an adjustment result for the signal generator. Preferably, the programmable logic device can also be used to send the adjustment result to the host computer for display to the user.

[0064] Step S208: Generate a detection result for the signal generator according to the interaction status and the adjustment result.

[0065] Specifically, the signal generator can use the programmable logic device to determine the position of the faulty module according to the current interaction status with the display module, and obtain the adaptive adjustment record of the faulty module according to the adjustment result of the faulty module. Obtain the interaction status between the adjusted signal generator and the display module, and determine whether there is still a fault status after the adaptive adjustment of the signal generator. In the case where there is no fault status, a detection result for the signal generator can be generated as: fault time - faulty module - adaptive adjustment record. In the case where there is still a fault status, a detection result for the signal generator can be generated as: fault time - faulty module - adaptive adjustment record - abnormal status to prompt the user to further adjust the faulty module.

[0066] In the above-mentioned method for determining the detection result, an interactive feedback signal from the display module to the signal generator is received; according to the interactive feedback signal, the interactive state between the display module and the signal generator is determined; in response to the judgment result that the interactive state is a fault state, an adjustment strategy corresponding to the fault state is executed to adjust the signal generator, and an adjustment result for the signal generator is generated; according to the interactive state and the adjustment result, a detection result for the signal generator is generated, which can not only classify the interactive state by using the interactive feedback signal, so as to adaptively adjust the signal generator in a targeted manner based on the interactive state, reduce the influence of external environmental factors on the detection result, and improve the adjustment efficiency of the signal generator, but also can further locate the specific fault position based on the interactive state and the adjustment result, which is beneficial to improve the determination accuracy and efficiency of the detection result.

[0067] In one embodiment, Figure 3 As shown, in step S202, an interactive feedback signal from the display module to the signal generator is received, which includes:

[0068] Step S302 , using a clock module of a signal generator to perform blanking processing on image data at a preset resolution to generate a corresponding image timing signal.

[0069] Specifically, in order to obtain the dot screen effect of the display module for image data at different resolutions, the image acquisition parameters of the signal generator can be pre-set, wherein the image acquisition parameters may include but are not limited to resolution parameters and timing parameters. Thus, the signal generator can use the bus to obtain image data at a preset resolution from an external storage unit. The clock module of the signal generator uses the timing parameters to perform blanking processing on the image data at the preset resolution, and generate image timing data corresponding to the blanking area size.

[0070] Step S304: Use the equalizer of the signal generator to perform equalization processing on the image time series signal to obtain a target time series signal.

[0071] Step S306: Send a target timing signal to the display module through the signal generator, instruct the display module to perform a point-to-screen operation using the target timing signal, and return an interactive feedback signal.

[0072] Specifically, the signal generator can perform processing operations such as packaging, encoding, scrambling, and parallel-to-serial conversion on the image timing signal according to the high-definition digital display transmission protocol to obtain a processed image timing signal. The processed image timing signal is sent to the display module, and the processed image timing signal is used to perform link training with the display module, such as clock synchronization training, signal packet loss rate training, signal distortion rate training, etc.

[0073] Record the link training results each time. At the physical medium layer of the signal generator, iteratively adjust the equalizer parameters of the signal generator according to the link training results. Use the adjusted equalizer to equalize the image timing signal generated by the signal generator, and send the equalized image timing signal to the display module. Record the link training results corresponding to the equalized image timing signal.

[0074] Repeat the link training operation until the link training reaches the preset stop times or the link training result reaches the preset accuracy rate, then determine that the link training passes and stop the subsequent link training operation. Record the target equalizer parameters used by the equalizer at this time. Subsequently, use the equalizer of the signal generator to equalize the image timing signal with the target equalizer parameters to obtain the corresponding target timing signal. Send the target timing signal to the display module through the signal generator, instruct the display module to perform the dot screen operation using the target timing signal, and return the interaction feedback signal corresponding to the target timing signal.

[0075] In this embodiment, by using the clock module of the signal generator to perform blanking processing to obtain the image timing signal, using the image timing signal to perform link training to iteratively adjust the equalizer parameters, and using the signal generator to send the target timing signal to the display module for dot screen and instruct the display module to return the corresponding interaction feedback signal, not only can the signal error between the signal generator and the display module be reduced, thereby improving the accuracy rate of the interaction feedback signal, but also the service life of the signal generator and the display module can be improved.

[0076] In one embodiment, the interaction feedback signal may include a hot plug signal (HTPDN) and a clock lock signal (LOCKN). Step S204, determine the interaction state between the display module and the signal generator according to the interaction feedback signal, including: obtain the first signal value of the hot plug signal, the second signal value of the clock lock signal, and the clock state value of the signal generator; determine the interaction state between the display module and the signal generator according to the first signal value, the second signal value, and the clock state value.

[0077] Specifically, the signal generator can determine the hot plug signal received from the hot plug interface and the clock lock signal received from the clock lock interface from the interaction feedback signal. Obtain the first signal value of the hot plug signal and the second signal value of the clock lock signal. Obtain the clock state value of its own clock module.

[0078] Such as Figure 4As shown, according to the first signal value, the second signal value, and the clock status value, determine the interaction status between the display module and the signal generator. For example, when the first signal value is 1, generate an interaction status of unconnected. At this time, the adjustment strategy corresponding to the interaction status can be to prompt abnormal wiring and power module, so as to facilitate the user to check the unconnected positions such as wiring and power module.

[0079] When the first signal value is 0 and the clock status value is in the unlocked state (UNLOCK), an interaction status of clock unlocked can be generated. At this time, the adjustment strategy corresponding to the interaction status can be to perform an initialization configuration on the clock module of the signal generator.

[0080] When the first signal value is 0, the second signal value is 1, and the clock status value is in the locked state (LOCK), an interaction status of training unlock failure can be generated. At this time, the adjustment strategy corresponding to the interaction status can be to adjust the parameters of the equalizer of the signal generator.

[0081] When the first signal value is 0, the second signal value is 0, and the clock status value is in the locked state (LOCK), an interaction status of normal can be generated.

[0082] Optionally, in some embodiments, the following signal judgment logic as shown in Table 4.1 can be stored in the signal generator:

[0083] VBO_HTPDN CLK_LOCK VBO_LOCKN Interaction state 1 X X Unconnected state 0 0 X Clock unlocked state 0 1 1 Training unlock state 0 1 0 Normal state

[0084] Table 4.1

[0085] Among them, VBO_HTPDN can be used to represent the first signal value of the hot plug signal received by the signal generator. CLK_LOCK can be used to characterize the clock status value of the clock module in the signal generator. VBO_LOCKN can be used to characterize the second signal value of the clock lock signal received by the signal generator. When the first signal value and / or the second signal value is 1, it can be used to represent a high level, and when the first signal value and / or the second signal value is 0, it can be used to represent a low level. When the first signal value and / or the second signal value is X, it can be used to represent that the signal value at this time can be either 0 or 1. When the clock status value is 1, it can be used to characterize the locked state, and when the clock status value is 0, it can be used to characterize the unlocked state. When the clock status value is X, it can be used to characterize that the clock module is in the locked state or the unlocked state at this time.

[0086] In this embodiment, by determining the interaction status between the signal generator and the display module according to the first signal value of the hot plug signal, the second signal value of the clock lock signal, and the clock status value of the signal generator clock module, the accuracy and determination efficiency of the interaction status can be improved.

[0087] In one embodiment, when the first signal value of the hot plug signal is zero and the clock status value of the clock module is in an unlocked state, the signal generator may generate an interaction status of clock unlocked. A fault judgment is performed on the current interaction status. In response to the judgment result that the clock unlocked state is a fault state, an adjustment strategy corresponding to the unlocked state is executed to initialize the configuration of the clock module of the signal generator, such as restarting the clock module or calibrating the time of the clock module according to the time of the Global Positioning System, etc., to generate an adjustment result for the signal generator.

[0088] In this embodiment, by adjusting the clock module of the signal generator in the unlocked state, an adaptive adjustment of the clock unlocked fault can be achieved, thus greatly saving the labor cost of adjusting the signal generator.

[0089] In one embodiment, as Figure 5 shown, a flowchart of the adjustment steps in the training unlock state is provided, including:

[0090] Step S502, when the first signal value is zero, the second signal value is one, and the clock status value is in the locked state, generate an interaction status of training unlock.

[0091] Specifically, the signal generator may generate an interaction status of training unlock between the signal generator and the display module when the first signal value of the hot plug signal fed back by the display module is zero, the second signal value of the clock lock signal is one, and the clock status value of the clock module is in the locked state.

[0092] Step S504, execute an adjustment strategy to adjust the equalizer of the signal generator, accumulate the equalization levels of the equalizer one by one, and generate and store the new equalization levels after accumulation.

[0093] Specifically, the signal generator may, in response to the judgment result that the current training unlock state is a fault state, execute an adjustment strategy corresponding to the training unlock state to gradually adjust the equalizer of the signal generator, accumulate the equalization levels of the equalizer one by one, and generate and store the new equalization levels obtained after accumulation. Subsequently, the new equalization levels are used to perform equalization processing on the image timing signal.

[0094] Step S506, record the number of occurrences of the training unlock state within a preset time period after adjustment.

[0095] Step S508, readjust the equalizer of the signal generator according to the number of occurrences and the adjustment strategy until the equalizer reaches the full equalization state, and generate an adjustment result.

[0096] Specifically, the signal generator can continuously detect the interaction state between the equalizer and the display module after each adjustment of the equalizer, record the number of occurrences of the training unlock state within a preset time period after the adjustment of the equalizer, such as the number of times of entering the training unlock state again within one millisecond. According to the number of occurrences of the training unlock state and the corresponding equalization adjustment information in the adjustment strategy, the equalizer of the signal generator is adjusted again until the equalization level of the equalizer reaches the maximum value, that is, the equalizer reaches the full equalization state, and a adjustment result for the signal generator is generated. Optionally, in some embodiments, if the signal generator does not enter the training unlock state or has reached the full equalization state within the preset time period after the adjustment, a adjustment result for the signal generator can be directly generated without adjusting the equalizer again.

[0097] In this embodiment, by adjusting the equalizer of the signal generator in the training unlock state, using the adjusted equalizer to perform equalization processing on the image timing signal, and performing link training on the display module using the equalized image timing signal, it is possible to achieve adaptive adjustment of the signal generator in the training unlock state, thereby reducing the impact of the training unlock state caused by external environmental reasons on the signal interaction communication between the signal generator and the display module, and reducing the adjustment cost of the signal generator.

[0098] In one embodiment, as Figure 6 shown, a flowchart of an abnormal information generation step is provided, including:

[0099] Step S602, when the interaction state is a fault state, record the number of executions of the execution adjustment strategy.

[0100] Step S604, compare the number of executions with a preset threshold.

[0101] Step S606, in response to the comparison result that the number of executions is greater than the preset threshold, generate abnormal information corresponding to the fault state.

[0102] Specifically, when the signal generator determines that the interaction state with the display module is a fault state, it can record the number of executions of the adjustment strategy corresponding to the fault state. Compare the number of executions within a preset period with a preset threshold. In response to the comparison result that the number of executions is greater than the preset threshold, generate abnormal information corresponding to the fault state, and send the abnormal information to the host computer to be displayed to the user, prompting that the current adaptive adjustment may fail and the user needs to adjust the faulty module by himself.

[0103] For example, in the case of an unlocked clock state, if the initialization configuration of the clock module of the signal generator exceeds five times, it is determined that the current clock module setting is abnormal and manual adjustment is required. Generate abnormal information corresponding to the unlocked clock module and display the abnormal information to the user in the host computer.

[0104] In this embodiment, by recording the number of executions of the corresponding adjustment strategy in the fault state, comparing the number of executions with a preset threshold, and generating abnormal information corresponding to the fault state when the number of executions is greater than the preset threshold, it is beneficial for users to quickly locate the faulty module and the fault problem, thereby improving the detection efficiency and accuracy of the signal generator.

[0105] In one embodiment, as Figure 7 shown, a structural block diagram of a large-size module self-checking system is provided, including: a data storage module 1, a timing generation module 2, a protocol conversion module 3, a signal detection module 4, a signal control module 5, a clock configuration module 6, an equalization adjustment module 7, a cache module 8, a bus interconnection module 9, a host computer 10, a storage unit 20, and a display module 30.

[0106] Among them, the storage unit 20 is connected to the data storage module 1. The data storage module 1 is connected to the timing generation module 2. The timing generation module 2 is connected to the protocol conversion module 3. The protocol conversion module 3 is connected to the signal detection module 4 and the display module 30. The signal detection module 4 is connected to the signal control module 5. The signal control module 5 is connected to the clock configuration module 6, the equalization adjustment module 7, the cache module 8, and the bus interconnection module 9. The clock configuration module 6 and the equalization adjustment module 7 are respectively connected to the protocol conversion module 3. The bus interconnection module 9 is connected to the host computer 10.

[0107] Specifically, a large-size module self-checking system as Figure 7 shown can be deployed in the signal generator, and the field programmable gate array deployed in the signal generator is used to implement functional operations such as logic control, data operation, and result feedback in the large-size module self-checking system. The user can send the set resolution parameters and timing parameters to the bus interconnection module 9 of the signal generator by operating the host computer 10.

[0108] The data storage module 1 reads the image data at the preset resolution from the storage unit 20 according to the resolution parameters of the bus interconnection module 9 and sends the image data at the preset resolution to the timing generation module 2. The timing generation module 2 performs blanking processing on the image data according to the timing parameters of the bus interconnection module 9, generates an image timing signal corresponding to the size of the blanking area, and sends it to the protocol conversion module 3.

[0109] The protocol conversion module 3 is used to perform processing operations such as packing, encoding, scrambling, and serial-to-parallel conversion on the image timing signal. The processed image timing signal is used for link training with the display module 30. According to the link training result, the number of equalizer stages of the protocol conversion module 3 is iteratively adjusted until the link training passes, and then the current target equalizer stage number is recorded. The protocol conversion module 3 uses the target equalizer stage number to perform equalization processing on the image timing signal to obtain the corresponding target timing signal and send it to the display module 30 for screen display.

[0110] The signal detection module 4 is used to continuously detect the interaction state between the protocol conversion module 3 and the display module 30 and receive the interaction feedback signal sent by the display module 30. According to the first signal value of the hot plug signal, the second signal value of the clock lock signal, and the clock state value of the clock module in the protocol conversion module 3 in the interaction feedback signal, the interaction state between the protocol conversion module 3 and the display module 30 is determined.

[0111] The signal control module 5 receives the interaction state determined by the signal detection module 4, judges the interaction state, and sends link normal information to the bus interconnection module 9 when the interaction state is normal. When the interaction state is a fault state, the clock configuration module 6 and / or the equalization adjustment module 7 are used to execute the adjustment strategy corresponding to the fault state to adjust the clock module or the equalizer of the protocol conversion module 3, and a regulation result for the protocol conversion module 3 is generated.

[0112] For example, in the unconnected state, the unconnected state information is fed back to the bus interconnection module 9 through the signal control module 5, so that the upper computer 10 prompts the user that there is an abnormality in the wiring and power supply parts.

[0113] In the state where the clock is not locked, the signal control module 5 accumulates the number of executions of the adjustment strategy corresponding to the state where the clock is not locked. When the number of executions is less than the preset threshold (for example, 5), the clock configuration module 6 is directly controlled to reconfigure the clock module of the protocol conversion module 3. If the clock is still not locked after adjustment and the number of executions of the adjustment strategy reaches the preset threshold, the clock not locked state information is fed back to the bus interconnection module 9 to indicate an abnormal clock setting.

[0114] In the training unlock state, the signal control module 5 controls the equalization adjustment module 7 to adjust the equalizer stages of the protocol conversion module 3 step by step. The occurrence times of re-entering the training unlock state within a preset time period after each adjustment are recorded, and the occurrence times and the corresponding equalization adjustment information are transmitted to the cache module 8. The protocol conversion module 3 is further adjusted according to the occurrence times and the current adjustment strategy until the full equalization state is reached. If during this period, the protocol conversion module 3 does not enter the training unlock state within the preset time period after adjustment or the protocol conversion module 3 has reached the full equalization state, the information in the cache module 8 is directly read and sent to the bus interconnection module 9.

[0115] Among them, the clock configuration module 6 can be used to access the clock module of the protocol conversion module 3 according to the control command of the signal control module 5 and perform recalibration processing on the clock module. And a calibration end instruction is sent to the signal control module 5 after each calibration of the clock module is completed.

[0116] The equalization adjustment module 7 can be used to access the equalizer of the protocol conversion module 3 according to the control instruction of the signal control module 5 and adjust the equalization stages of the equalizer in a form of cumulative addition one by one. After each adjustment of the equalizer is completed, the equalizer adjustment information and the adjustment end instruction are sent to the signal control module 5.

[0117] In this embodiment, by using the signal detection module to detect the interaction state between the protocol conversion module and the display module of the signal generator in real time, determining the real-time interaction state between the protocol conversion module and the display module based on the interaction feedback signal, and using the signal control module to control the corresponding adaptive adjustment modules - the clock configuration module and / or the equalization adjustment module to access and adjust the clock module and / or the equalizer in the protocol conversion module according to the interaction state, not only can the adaptive adjustment of the protocol conversion module be realized, thereby reducing the influence of external environmental factors on the detection result and improving the adjustment efficiency of the signal generator, but also the specific fault location can be further located based on the interaction state and the adjustment result, which is beneficial to improving the determination accuracy and determination efficiency of the detection result.
