Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments 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 persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In order to unify the differences in different performance inspection processes, reduce the complexity of operations, and improve inspection efficiency, in the embodiment of the present invention, a method for detecting the TV screen end is designed. The configuration parameters are stored, and corresponding inspection commands are generated, so as to inspect the performance of the TV screen and obtain inspection results.

The solution of the present invention will be described in detail below through specific examples. Of course, the present invention is not limited to the following examples.

Referring to Fig. 1, in the embodiment of the present invention, the specific flow of the TV screen end detection method is as follows:

Step 100: The terminal sends a corresponding I2C command to the TV based on the user's instruction.

In practical applications, the user determines the corresponding I2C command according to the detection requirements of the TV screen.

For example, the user checks the backlight status of the TV screen, first determines the model of the TV screen and the supporting chip, and then determines the I2C command corresponding to the model of the TV screen and the supporting chip.

Further, the terminal sends a corresponding I2C command to the TV based on the user's instruction.

Step 110: The TV receives the I2C command sent by the terminal.

In practical applications, the TV receives the I2C command sent by the terminal based on the user's instruction through the serial port, wherein the I2C command carries configuration parameters corresponding to screen settings of the TV.

The configuration parameter includes an I2C device address, and/or, a command parameter, and optionally, the configuration parameter may also include a register address, and/or, an I2C command length.

Step 120: The TV stores the configuration parameters carried in the I2C command.

In practical applications, the television determines the storage method of the configuration parameters. Optionally, the storage method may be stored in a cache area, may also be stored in a disk storage area, or may be stored in a flash memory.

Then, the TV stores the configuration parameters in the storage space through the interface corresponding to the serial port.

For example, the TV stores configuration parameters in a high-speed flash memory (Embedded Multi Media Card, EMMC) through the Linux read-write interface corresponding to the serial port, namely filp.open→filp.f_op.llseek→filp.f_op.write→filp.close. Wherein, the configuration parameters include an I2C device address and command parameters.

For another example, the TV stores configuration parameters in the memory through the Linux read-write interface corresponding to the serial port, namely filp.open→filp.f_op.llseek→filp.f_op.write→filp.close, wherein the configuration parameters include I2C command parameters , device address, I2C command length, and register address.

In this way, the TV can modify the configuration parameters stored in the storage space through the interface corresponding to the serial port, so that when calling the configuration parameters, the configuration parameters can be directly read from the storage space, avoiding manual input configuration parameters, and avoid the code compilation process after inputting new code, which improves the inspection efficiency. Further, when inspecting different performances, only need to modify the configuration parameters corresponding to the performance settings to be inspected, and the corresponding The test command avoids directly inputting the test command corresponding to each performance to be tested, thereby shielding the difference between different performance test processes.

Step 130: When the television determines that the debugging process is triggered, it generates a corresponding inspection command based on the configuration parameters, and runs the inspection command to inspect the performance of the TV screen to obtain an inspection result.

In practical applications, when the TV determines that the debugging process is triggered, it generates a corresponding inspection command based on configuration parameters, where the configuration parameters include an I2C device address, and/or, command parameters, and optionally, the configuration parameters may also include register addresses, and /or, I2C command length.

For example, the TV receives the I2C command echo ic 0x34 70x02 0xa1 0x00 0x0c 0xd6 0x00>/proc/msp/pdm sent by the terminal based on the user's instruction through the serial port, where the configuration parameters include the command parameter 0x020xa1 0x00 0x0c 0xd6 0x00, the device address 0x34 and the command Length 7. Further, the television generates the first verification command xw 2 0x100 0x34 7 0x02 0xa1 0x00 0x0c 0xd6 0x00 based on the configuration parameters.

Then, the TV runs the test command to test the performance of the screen of the TV, and obtains the test result.

Optionally, each performance test of the TV may be one or any combination of backlight, jitter, sliding screen, and flickering screen.

For example, the TV operation check command checks the backlight status of the screen of the TV.

For another example, the television operation inspection command performs a shaking state inspection on the screen of the television.

For another example, the TV running check command checks the splash screen status of the TV screen.

For another example, the TV running inspection command performs a sliding screen state inspection on the screen of the TV.

Further, the TV will judge whether the TV is running normally according to the test result.

Determine whether the TV is operating normally according to the test results;

If so, display the inspection result to the user, and run the inspection command again to inspect the performance of the TV again until the set number of inspections is reached;

Otherwise, display the test result to the user, receive a new I2C command sent by the terminal, modify the test command, generate a new test command, and test the performance of the TV again based on the new test command.

In this way, according to the test result, when the test result shows that the TV is running normally, the user can use the same command to repeatedly test the TV to determine whether there is an occasional problem. When the inspection result shows that the TV is running abnormally, the inspection command is modified accordingly, and the modified inspection command is run again, so as to determine the specific cause of the abnormality of the TV.

The above-mentioned embodiments will be further described in detail below using specific embodiments.

Referring to Fig. 3, in the embodiment of the present invention, preset N detections can be performed on the TV end, and the specific process is as follows:

To test the performance of the TV screen, the user first determines the hardware specification of the TV screen, and then determines the I2C command corresponding to the hardware specification setting of the TV screen, and further connects the terminal to the TV through the serial port, and sends it to the TV through the serial port I2C commands.

Step 300: The TV receives the I2C command through the serial port.

Step 301: the TV calls the corresponding interface, and writes the configuration parameters carried by the I2C command into the EMMC.

Step 302: The system of the TV is restarted to perform hardware initialization.

Step 303: The TV performs software initialization, and generates a corresponding inspection command based on the read configuration parameters.

Step 304: The TV checks the backlight status of the screen based on the generated check command, and completes screen initialization.

Step 305: The system starts up completely.

Step 306: The TV obtains the inspection result according to the screen state.

Step 307: Based on the obtained test result, the television determines whether there is an abnormality, and if so, executes step 310; otherwise, executes step 308.

Step 308: The TV counts the times of normal operation, and adds one to the times.

Step 309: The TV judges whether the counted number of continuous normal operations reaches the set inspection number, and if so, stops the inspection; otherwise, executes step 300.

Step 310: The TV clears the counted times to zero.

Step 311: The TV receives a new I2C command through the serial port.

Hereinafter, a specific application scenario is adopted to further describe the foregoing embodiment in detail.

Assuming that the user checks the backlight status of the TV screen, first determine that the model of the TV screen is HD500DU-B52 and the supporting chip is NTK72324, and then determine the I2C command set by the corresponding TV screen model HD500DU-B52 and supporting chip NTK72324 If it is echo ic 3 7 0x02 0xa1 0x00 0x0c 0xd6 0x0>/proc/msp/pdm, then the user connects the terminal to the TV through the serial port and sends I2C commands to the TV through the serial port.

The TV receives the I2C command echo ic 0x34 7 0x020xa1 0x00 0x0c 0xd6 0x00>/proc/msp/pdm sent by the terminal based on the user's command through the serial port, and based on the I2C command echo ic 0x34 7 0x02 0xa10x00 0x0c 0xd6 0x00>/proc/msp/pdm , through the Linux read-write interface docked with the serial port, that is, filp.open→filp.f_op.llseek→filp.f_op.write→filp.close, write configuration parameters in EMMC, where the configuration parameters include command parameters 0x02 0xa1 0x00 0x0c 0xd6 0x00, device address 0x34, and command length 7.

The system of the TV is restarted, hardware initialization and software initialization are performed, and in the process of software initialization, based on the configuration parameters, the first verification command xw 2 0x100 0x34 7 0x02 0xa1 0x00 0x0c 0xd60x00 is generated, and based on the first verification command, the TV Check the backlight status of the screen and complete the screen initialization. At this time, the system starts up.

The TV obtains the first inspection result according to the screen state, and judges that the TV is running abnormally according to the first inspection result.

Further, the TV first clears the counted number of normal operations, and then the TV sends a new I2C command echo ic 3 7 0x02 0xa1 0x10 0x0c 0x0a 0x0>/proc/msp/pdm based on the user's new command, for the first The first test command xw 2 0x100 0x34 7 0x02 0xa1 0x00 0x0c 0xd6 0x00 is modified, restart the system, perform hardware initialization and software initialization, and generate the second test command xw 2 0x100 0x34 based on the configuration parameters during the software initialization process 7 0x02 0xa1 0x10 0x0c 0x0a 0x00, and based on the second check command xw 2 0x100 0x34 7 0x02 0xa1 0x10 0x0c 0x0a 0x00, check the backlight status of the TV screen again.

The TV obtains the second inspection result, and judges that the TV is running normally according to the second inspection result, and counts the number of times that the TV is running normally as 1.

The user presets the number of checks to be 3. Since the number of normal operations 1 is lower than the set number of checks 3, the TV restarts the system, performs hardware initialization and software initialization, and runs the second check command xw 2 0x1000x34 7 0x02 0xa1 0x10 0x0c 0x0a 0x00, check the backlight status of the TV screen, obtain the third inspection result, and judge that the TV is running normally based on the third inspection result, and the number of times 2 of judging that the operation is normal does not reach the set number of inspections 3 .

The TV restarts the system, initializes the hardware and software, runs the second test command xw2 0x100 0x34 7 0x02 0xa1 0x10 0x0c 0x0a 0x00 again, checks the backlight status of the TV screen, obtains the fourth test result, and based on the fourth test result Determine that the TV is functioning normally. When the number of times 3 determined by the TV to run normally reaches the set number of inspections 3, the inspection process is stopped.
