Referring to fig. 2, fig. 2 is a schematic flowchart of a display screen fault diagnosis method according to a first embodiment of the present invention, where the display screen fault diagnosis method includes:
step S10, when the current enabled display screen fault is detected, switching to a display screen fault diagnosis mode;
according to the application of the current display screen, detecting the fault condition of the display screen after the display screen is started, wherein the fault detection of the display screen can be carried out only after the display screen is normally started and when the application fault of the display screen occurs, namely, the application mode of the current display screen is switched into a display screen fault diagnosis mode. Based on the normal application of the display screen, the display screen is enabled after the screen clicking function application of the display screen needs to be executed, that is, before the step of switching to the display screen fault diagnosis mode when the currently enabled display screen fault is detected, the method further comprises the following steps:
receiving a starting-up enabling signal and acquiring screen point information;
and performing screen clicking according to the time sequence of the screen clicking information to start the display screen.
In the display screen applied in this embodiment, the enabling operation of the display screen application includes a pointing screen and an enabling instruction, so that, in relation to the connection relationship of the components of the display screen, the host sends a video signal, a backlight enabling signal, a backlight PWM signal, and a power-on enabling signal to the display screen through the transmission chip to enable the display screen, and the host and the display screen are transmitted through the LVDS wire, and fig. 4 can be viewed in a related implementation manner, and fig. 4 is a schematic diagram of a frame structure of a split machine system with the display screen. When the display screen is applied, the display screen acquires corresponding screen dot information through the deserializing chip 948 and then transmits the screen dot information to the MCU for processing, so that when the MCU is powered on, the MCU first acquires the power-on enable signal sent by the host, then acquires the screen dot information, and performs screen dot through a time sequence, so that the display screen starts to operate normally, i.e., the display screen is started normally.
When the fault detection operation of the display screen under normal starting is involved, because the display screen is in touch application operation, when the fault operation of the display screen is detected, the fault operation can be realized by receiving an abnormal user touch command, namely the step when the fault of the currently started display screen is detected comprises the following steps:
receiving a user touch command, and confirming whether the user touch command is a repeated touch command;
and confirming the display screen fault when the user touch command is confirmed to be a repeated touch command.
After the current display screen is normally started, receiving a user touch command, wherein the user touch command is a functional application command initiated by a user based on the functions of the display screen, the user correspondingly initiates the display screen functional application of the functional area through gestures such as clicking/touching/sliding and the like in the related functional area of the screen of the display screen, generally, when the user initiates the user touch command through gestures such as clicking/touching/sliding and the like, if the display screen cannot execute the related application functions of the user touch command within a reflection time, the user can be caused to repeatedly initiate the user touch command, therefore, in the judgment process of judging whether the display screen is in a fault or not through the received user touch command, the statistics of the times of the user touch command is also involved, namely, the step of confirming the fault of the display screen when the user touch command is confirmed to be a repeated touch command, the method comprises the following steps:
counting the repetition times of the user touch command when receiving the repeated user touch command;
and if the repetition times of the user touch command is larger than or equal to a preset numerical value, determining that the user touch command is a repeated touch command.
When a user touch command is received, if the user touch command is initiated repeatedly, namely when the same user touch command is received for multiple times, the user touch command is defined as a repeated touch command, but the problem related to a hardware memory of a display screen is solved, the user touch command may not be reacted immediately when the user touch command is executed, so that the repeated times of the repeated touch command can be defined as a judgment reference of the repeated touch command for judging whether the display screen is in failure or not, after the repeated touch command is received, the repeated times of the user touch command are counted, the counted repeated times are compared with a preset value of a preset limited repeated time upper limit, and when the repeated times of the user touch command are confirmed to be greater than or equal to the preset value, the user touch command is confirmed to be the repeated touch command. Further, when a preset value of the upper limit of the number of repetitions is predefined, the device memory may be set to the response time of the function application of the display screen correspondingly when the device memory operates based on the display screen.
In addition, when determining whether the user touch command is a repeated touch command based on the received user touch command, it is further required to verify whether the user touch command corresponding to the repeated touch command is the same touch command in consideration of accuracy of the failure determination, and when determining whether the user touch command is the same touch command based on the functional application of the display screen, it is required to perform determination based on an initiation area of the user touch command, so the display screen failure diagnosis method further includes:
confirming whether the user touch command is initiated through the same touch command area;
and if the user touch command is initiated through the same touch command area, confirming that a repeated user touch command is received.
When a user touch command is received and multiple user touch commands are received within a preset time range, whether the received user touch commands are the same touch command or not can be judged. When a preset time range of a user touch command is limited, namely a receiving frequency of the user touch command within a certain time is based, corresponding limitation can be performed on the display screen based on an upper limit of a reflecting time of the user touch command, so that when multiple user touch commands are received within the limited preset time range, whether the user touch command is a repeated touch command can be obtained by judging whether the user touch command is initiated by the same touch command area, the limitation of the touch command area is related, the touch command area can be limited based on the touch function area divided by the display screen function application area, namely when the trigger command areas of the received multiple user touch commands are determined to be the same function application area, the receiving of the repeated touch command is confirmed.
Step S20, acquiring a diagnosis value output by a display screen control chip, and calling a built-in display screen fault solution based on a fault code corresponding to the diagnosis value;
when the display screen is determined to be in fault based on the received user touch command, acquiring a diagnostic value output by a control chip of the display screen, in general, after the display screen is switched to a fault diagnosis mode, the control chip of the display screen directly outputs a diagnostic value based on the current display screen fault, wherein the diagnostic value is a preset identification value based on fault information, and the control chip based on the display screen comprises a touch chip and diagnostic values of PWM, EN and LVDS transmitting and receiving chips, namely, when the display screen determines that the display screen equipment is in fault, the diagnostic value of the fault is output through a related control chip based on the specific setting of the fault so as to determine which fault is based on the diagnostic value, thus directly detecting the diagnostic value output by the control chip of the display screen, and acquiring a fault code corresponding to the diagnostic value based on the association relationship between the diagnostic value and the preset fault code, and calling a pre-built-in display screen fault solution based on the fault code, wherein the display screen fault solution is a preset solution based on a diagnostic value output by a current control chip, and the display screen fault solution is mainly expressed in a form which can be displayed by the display screen, such as images and characters or image and character combined information.
In addition, in view of the problem of device application caused by the display screen failure, when the display screen fails, the fault registration operation can be performed based on the diagnostic value of the failure, so the steps of obtaining the diagnostic value output by the display screen control chip and calling the built-in display screen failure solution based on the failure code corresponding to the diagnostic value also include:
generating display screen fault diagnosis information according to the diagnosis operation of the display screen fault;
and sending the display screen fault diagnosis information to a preset memory for storage.
The method comprises the steps of generating display screen fault diagnosis information based on fault diagnosis operation of display screen faults, wherein the display screen fault diagnosis information comprises fault time, fault conditions, diagnosis values, fault codes and corresponding display screen fault solutions, sending the generated display screen fault diagnosis information to a preset memory for storage, wherein in the display screen function application, the preset memory is an EEPROM (Electrically Erasable Programmable read only memory), and the display screen fault diagnosis information is a storage chip with no data loss after power failure, can erase existing information on a computer or special equipment, can be reprogrammed and is generally used in plug and play.
In addition, in view of the host computer judgment application of the display screen fault, the relevant fault information of the display screen fault needs to be pushed to the host computer for registration, in the functional application of the display screen hardware equipment applied in the invention, the display screen does not have an interface for data transmission, when the subsequent maintenance needs to know the fault reason, the fault code in the display screen needs to be called to the host computer end at the moment, and the fault information stored in the preset memory can be directly read for data transmission, therefore, the display screen fault diagnosis method further comprises the following steps:
and reading the stored display screen fault diagnosis information in a preset memory, and sending the diagnosis information to a serializer for registering.
According to the display screen fault diagnosis information stored in the preset memory at present, the display screen fault diagnosis information is read from the preset memory and is sent to the serializer for registering, so that the host calls the relevant display screen fault data information.
And step S30, outputting the called display screen fault solution to a display screen for display.
And outputting the called display screen fault solution to a display screen for display according to the fault diagnosis operation after the current display screen has faults, wherein the display screen fault solution is related information which can be displayed by the display screen and comprises related guide information of images, characters or images and characters. And guiding a current user to solve the current display screen fault based on the display screen fault solution of the display screen system.
In the embodiment, the incidence relation between the fault code corresponding to the diagnosis value and the fault solution is preset, and the fault solution can be correspondingly acquired through the diagnosis value and displayed on the display screen when the display screen is in fault, so that a technical scheme for self-diagnosis and fault solution of the display screen is provided for a user, the user can quickly know the fault of the display screen and provide the fault solution for quickly solving the fault problem of the display screen.

step S40, newly building a display screen fault solution corresponding to the display screen fault, and generating a fault code of the display screen fault solution;
