Embodiment one:

fig. 1 shows a flowchart of a first data storage method according to an embodiment of the present application, where the data storage method is applied to a terminal device, and is described in detail as follows:

step S101, an ADJ duty cycle adjustment instruction is sent to a TV main board, wherein the ADJ duty cycle adjustment instruction carries information of an ADJ duty cycle so as to instruct the TV main board to correspondingly set the current ADJ duty cycle according to the information of the ADJ duty cycle.

Specifically, if the adjustment trigger information is detected, an ADJ duty cycle adjustment instruction is sent to the TV main board through a wired communication mode. The adjustment triggering information is information for triggering the terminal equipment to send an ADJ duty ratio adjustment instruction to the TV main board.

By way of example and not limitation, the adjustment trigger information may be: information indicating that the terminal device enters a specified mode, wherein the specified mode is used for: the backlight current values corresponding to at least two different ADJ duty ratios are tested, and the corresponding relation between the at least two different ADJ duty ratios and the backlight current values is obtained, and the wired communication mode can be as follows: the serial communication mode can be a two-wire serial bus (I2C, inter-Integrated Circuit) communication mode.

By way of example and not limitation, the step S101 specifically includes: the terminal equipment sends an ADJ duty cycle adjustment instruction to the TV main board according to a preset duty cycle, wherein the preset duty cycle comprises: a preset minimum ADJ duty cycle and a preset maximum duty cycle, the preset minimum ADJ duty cycle may be 0%. Specifically, the terminal device determines an initial value of an ADJ duty cycle according to a preset duty cycle, and sends an ADJ duty cycle adjustment instruction to the TV main board according to the initial value of the ADJ duty cycle, wherein information of the ADJ duty cycle carried in the ADJ duty cycle adjustment instruction is the initial value of the ADJ duty cycle, and the initial value of the ADJ duty cycle is greater than or equal to a preset minimum ADJ duty cycle and is smaller than the preset maximum duty cycle.

Step S102, reading a current value of an electronic load module forming a current loop with the TV main board, and recording a corresponding relation between the current ADJ duty ratio and the read current value.

The reading the current value of the electronic load module forming the current loop with the TV main board specifically comprises the following steps: if the terminal equipment receives the successful setting feedback information of the TV main board, the current value of the electronic load module forming a current loop with the TV main board is read through a wired communication mode. The successful feedback information of the setting is as follows: feedback information indicating that the TV main board has successfully set the current ADJ duty cycle. The electronic load module may be composed of a number of light emitting diode lamps.

In this embodiment, since the electronic load module and the TV main board form a loop, the current value read from the electronic load module is the current value output by the TV main board, that is, is equal to the backlight current value.

In some embodiments, because communication between the terminal device and the electronic load module may be interrupted, the terminal device may occasionally not read the current value of the electronic load module forming the current loop with the TV motherboard, so, in order to be able to read the current value corresponding to the current ADJ duty cycle as much as possible, if the current value of the electronic load module forming the current loop with the TV motherboard is not read, the current value of the electronic load module forming the current loop with the TV motherboard is read unchanged, the current value of the electronic load module forming the current loop with the TV motherboard is read again, if the current value of the electronic load module forming the current loop with the TV motherboard is not read for N consecutive times, in order to avoid wasting test time, the current value of the electronic load module forming the current loop with the TV motherboard is not read any more, and if the terminal device is in a specified mode, the specified mode is exited, where N is equal to a preset number of times of reading threshold.

In some embodiments, before said step S102, it comprises: establishing a file, correspondingly, recording the corresponding relation between the current ADJ duty ratio and the read current value, and including: and recording the corresponding relation between the current ADJ duty ratio and the read current value in the file. The corresponding relation between the current ADJ duty cycle and the read current value is recorded in the file, so that a tester can conveniently review the corresponding relation between the current ADJ duty cycle and the read current value.

Step S103, determining a new ADJ duty cycle according to a preset variable quantity and a current ADJ duty cycle, indicating the TV main board to set the current ADJ duty cycle as the new ADJ duty cycle, reading a new current value of an electronic load module forming a current loop with the TV main board, and recording a corresponding relation between the new ADJ duty cycle and the read new current value.

And if the new ADJ duty cycle is smaller than the preset maximum duty cycle, returning to the step of determining the new ADJ duty cycle according to the preset variable quantity and the current ADJ duty cycle and the subsequent steps.

Wherein, the determining a new ADJ duty cycle according to the preset variation and the current ADJ duty cycle includes: and determining the sum between the preset variation and the current ADJ duty cycle as a new ADJ duty cycle.

By way of example and not limitation, the preset variation is greater than 0%, assuming that the preset variation is 0.5%, the current ADJ duty cycle is 0%, the terminal device determines the sum of the preset variation 0.5% and the current ADJ duty cycle 0% to be a new ADJ duty cycle, instructs the TV main board to set the current ADJ duty cycle to be the new ADJ duty cycle 0.5%, and then after the TV main board sets the current ADJ duty cycle to be the new ADJ duty cycle 0.5%, the terminal device reads a new current value of the electronic load module forming a current loop with the TV main board, assuming to be 154 milliamps, and records a correspondence of the new ADJ duty cycle 0.5% to 154 milliamps. Assuming that the preset maximum duty cycle is 100%, since the new ADJ duty cycle 0.5% is smaller than the preset maximum duty cycle 100%, the terminal device takes the ADJ duty cycle 0.5% recorded last time as the current ADJ duty cycle, determines the sum 1% of the preset variation 0.5% and the current ADJ duty cycle 0.5% as the new ADJ duty cycle, instructs the TV main board to set the current ADJ duty cycle to the new ADJ duty cycle 1%, and then after the TV main board sets the current ADJ duty cycle to the new ADJ duty cycle 1%, reads a new current value of the electronic load module forming a current loop with the TV main board, assuming 159 milliamp, and records the correspondence between the new ADJ duty cycle 1% and 159 milliamp. Since the new ADJ duty cycle is 1% less than the preset maximum duty cycle of 100%, taking the last recorded ADJ duty cycle as the 1% current ADJ duty cycle, returning to the step of determining the new ADJ duty cycle according to the preset variation and the current ADJ duty cycle and the step of determining the new ADJ duty cycle according to the preset variation and the current ADJ duty cycle until the new ADJ duty cycle is greater than the preset maximum duty cycle of 100%.

Optionally, after the step of determining the new ADJ duty cycle according to the preset variation and the current ADJ duty cycle and the subsequent steps if the new ADJ duty cycle is smaller than the preset maximum duty cycle, the method includes: and generating a corresponding curve according to the recorded corresponding relation between each ADJ duty ratio and the current value.

As an example, but not by way of limitation, a coordinate system in which a corresponding curve is generated from the recorded correspondence relationship between each ADJ duty cycle and current value may be established as shown in fig. 2, with the horizontal axis of the coordinate axis being the ADJ duty cycle and the vertical axis being the current value.

In some embodiments, after the generating the corresponding curve according to the recorded correspondence between the respective ADJ duty cycles and the current values, the method further includes: and if the bending degree of the curve is smaller than or equal to a preset bending degree threshold value, judging that the TV main board is in a normal state.

The curvature degree can be represented by curvature, and correspondingly, the preset curvature degree threshold is a preset curvature threshold, and if the curvature of each point on the curve is smaller than or equal to the preset curvature threshold, the TV main board is judged to be in a normal state.

In some embodiments, after the generating the corresponding curve according to the recorded correspondence between the respective ADJ duty cycles and the current values, the method further includes: and if the bending degree of the curve is larger than a preset bending degree threshold value, judging that the TV main board is in an abnormal state.

Specifically, if a curve part with the bending degree larger than a preset bending degree threshold exists in the curve, judging that the TV main board is in an abnormal state.

The terminal equipment can judge whether the TV main board is in a normal state or an abnormal state according to the curve bending degree and the preset bending degree threshold value, and the process does not need the participation of testers, so that the testing efficiency of the TV main board can be greatly improved, and a large amount of labor cost is saved.

Optionally, in order to enable the tester to know that the TV main board is in an abnormal state, after the determining that the TV main board is in an abnormal state, the method includes: and outputting prompt information, wherein the prompt information comprises information that the TV main board is in an abnormal state.

By way of example and not limitation, the prompt is output based on an identification of the TV motherboard. For example, assume that the identifier of the TV motherboard is number 01, and correspondingly, information indicating that the TV motherboard with the number 01 is in an abnormal state is output.

In the embodiment of the application, firstly, terminal equipment can send an ADJ duty cycle adjustment instruction to a TV main board to instruct the TV main board to correspondingly set the current ADJ duty cycle according to the information of the ADJ duty cycle, further read a current value of an electronic load module forming a current loop with the TV main board, record the corresponding relation between the current ADJ duty cycle and the read current value, namely, the terminal equipment can record the corresponding relation between one ADJ duty cycle and the read current value; in addition, the terminal device can determine a new ADJ duty cycle according to a preset variable quantity and a current ADJ duty cycle, instruct the TV main board to set the current ADJ duty cycle as the new ADJ duty cycle, read a new current value of an electronic load module forming a current loop with the TV main board, record a corresponding relation between the new ADJ duty cycle and the read new current value, that is, the terminal device can record a corresponding relation between the new ADJ duty cycle and the read current value, and the terminal device can record corresponding relations between two different ADJ duty cycles and the read current value in combination with the previous steps. Further, if the new ADJ duty cycle is smaller than the preset maximum duty cycle, the step of determining the new ADJ duty cycle according to the preset variation and the current ADJ duty cycle and the subsequent steps are returned, that is, if the new ADJ duty cycle is smaller than the preset maximum duty cycle, the terminal device can record the correspondence between more than two different ADJ duty cycles and the read current value. As can be seen from the above, in the embodiment of the present application, the terminal device can obtain the correspondence between at least two different ADJ duty ratios and the read current value. Because the current value output by the TV main board is the backlight current value, the TV main board and the electronic load module form a current loop, and therefore, the current value read by the terminal equipment from the electronic load module is equal to the current value output by the TV main board, namely, the backlight current value, and therefore, the terminal equipment can acquire the corresponding relation between at least two different ADJ duty ratios and the backlight current value. The data storage method does not need the participation of testers, so that the data storage efficiency can be greatly improved, and a large amount of labor cost is saved.

Embodiment III:

fig. 4 shows a schematic structural diagram of a data storage system provided by an embodiment of the present application, where the data storage system includes a terminal device 401 and an electronic load module 402, and the data storage device includes:

Specifically, if the terminal device 401 detects the adjustment trigger information, it sends an ADJ duty cycle adjustment instruction to the TV motherboard through a wired communication manner. The adjustment triggering information is information for triggering the terminal equipment to send an ADJ duty ratio adjustment instruction to the TV main board.

By way of example and not limitation, the terminal device 401 is specifically configured to: sending an ADJ duty cycle adjustment instruction to a TV main board according to a preset duty cycle, wherein the preset duty cycle comprises: the preset minimum ADJ duty cycle and the preset maximum duty cycle, wherein the preset minimum ADJ duty cycle can be 0, and the preset maximum duty cycle is the preset maximum ADJ duty cycle. Specifically, an initial value of an ADJ duty cycle is determined according to a preset duty cycle, an ADJ duty cycle adjustment instruction is sent to a TV main board according to the initial value of the ADJ duty cycle, and information of the ADJ duty cycle carried in the ADJ duty cycle adjustment instruction is the initial value of the ADJ duty cycle, wherein the initial value of the ADJ duty cycle is larger than or equal to a preset minimum ADJ duty cycle and smaller than a preset maximum duty cycle.

The electronic load module 402 forms a current loop with the TV motherboard.

The terminal device 401, when executing the reading of the current value of the electronic load module forming the current loop with the TV motherboard, is specifically configured to: if the terminal equipment receives the successful setting feedback information of the TV main board, the current value of the electronic load module forming a current loop with the TV main board is read through a wired communication mode.

The terminal device 401 is specifically configured to, when executing the determination of the new ADJ duty ratio according to the preset variation and the current ADJ duty ratio: and determining the sum between the preset variation and the current ADJ duty cycle as a new ADJ duty cycle.

By way of example and not limitation, the preset variation is greater than 0%, assuming that the preset variation is 0.5%, the current ADJ duty cycle is 0%, the terminal device 401 determines the sum of the preset variation 0.5% and the current ADJ duty cycle 0% as a new ADJ duty cycle, instructs the TV main board to set the current ADJ duty cycle to the new ADJ duty cycle 0.5%, and then after the TV main board sets the current ADJ duty cycle to the new ADJ duty cycle 0.5%, the terminal device 401 reads a new current value of the electronic load module forming a current loop with the TV main board, assuming to be 154 milliamps, and records a correspondence of the new ADJ duty cycle 0.5% and 154 milliamps. Assuming that the preset maximum duty cycle is 100%, since the new ADJ duty cycle 0.5% is smaller than the preset maximum duty cycle 100%, the terminal device 401 takes the ADJ duty cycle 0.5% recorded last time as the current ADJ duty cycle, determines the sum 1% between the preset variation 0.5% and the current ADJ duty cycle 0.5% as the new ADJ duty cycle, instructs the TV main board to set the current ADJ duty cycle to the new ADJ duty cycle 1%, and then after the TV main board sets the current ADJ duty cycle to the new ADJ duty cycle 1%, the terminal device 401 reads a new current value of the electronic load module forming a current loop with the TV main board, assuming 159 milliamperes, and records the correspondence between the new ADJ duty cycle 1% and 159 milliamperes. Since the new ADJ duty cycle is 1% less than the preset maximum duty cycle of 100%, taking the last recorded ADJ duty cycle as the 1% current ADJ duty cycle, returning to the step of determining the new ADJ duty cycle according to the preset variation and the current ADJ duty cycle and the step of determining the new ADJ duty cycle according to the preset variation and the current ADJ duty cycle until the new ADJ duty cycle is greater than the preset maximum duty cycle of 100%.

Optionally, after the terminal device 401 executes the step of determining the new ADJ duty cycle according to the preset variation and the current ADJ duty cycle and the subsequent steps if the new ADJ duty cycle is smaller than the preset maximum duty cycle, the method is further used for: and generating a corresponding curve according to the recorded corresponding relation between each ADJ duty ratio and the current value.

As an example and not by way of limitation, the terminal device 401 may establish a coordinate system in which the terminal device 401 generates a corresponding curve according to the recorded correspondence relationship between each ADJ duty cycle and the current value, as shown in fig. 2, with the horizontal axis of the coordinate axis being the ADJ duty cycle and the vertical axis being the current value.

Specifically, if the curve has a curve portion with a bending degree greater than a preset bending degree threshold, the terminal device 401 determines that the TV main board is in an abnormal state.

Alternatively, in order to enable the tester to know that the TV main board is in an abnormal state, therefore, after the terminal device 401 performs the determination that the TV main board is in an abnormal state, it is further configured to: and outputting prompt information, wherein the prompt information comprises information that the TV main board is in an abnormal state.

By way of example and not limitation, the terminal device 401 outputs a prompt message according to the identification of the TV main board. For example, assume that the identifier of the TV motherboard is number 01, and correspondingly, information indicating that the TV motherboard with the number 01 is in an abnormal state is output.

In the embodiment of the application, firstly, terminal equipment can send an ADJ duty cycle adjustment instruction to a TV main board to instruct the TV main board to correspondingly set the current ADJ duty cycle according to the information of the ADJ duty cycle, further read a current value of an electronic load module forming a current loop with the TV main board, record the corresponding relation between the current ADJ duty cycle and the read current value, namely, the terminal equipment can record the corresponding relation between one ADJ duty cycle and the read current value; in addition, the terminal device can determine a new ADJ duty cycle according to a preset variable quantity and a current ADJ duty cycle, instruct the TV main board to set the current ADJ duty cycle as the new ADJ duty cycle, read a new current value of an electronic load module forming a current loop with the TV main board, record a corresponding relation between the new ADJ duty cycle and the read new current value, that is, the terminal device can record a corresponding relation between the new ADJ duty cycle and the read current value, and the terminal device can record corresponding relations between two different ADJ duty cycles and the read current value in combination with the previous steps. Further, if the new ADJ duty cycle is smaller than the preset maximum duty cycle, the step of determining the new ADJ duty cycle according to the preset variation and the current ADJ duty cycle and the subsequent steps are returned, that is, if the new ADJ duty cycle is smaller than the preset maximum duty cycle, the terminal device can record the correspondence between more than two different ADJ duty cycles and the read current value. As can be seen from the above, in the embodiment of the present application, the terminal device can obtain the correspondence between at least two different ADJ duty ratios and the read current value. Because the current value output by the TV main board is the backlight current value, the TV main board and the electronic load module form a current loop, and therefore, the current value read by the terminal equipment from the electronic load module is equal to the current value output by the TV main board, namely, the backlight current value, and therefore, the terminal equipment can acquire the corresponding relation between at least two different ADJ duty ratios and the backlight current value. Because the data storage system does not need the participation of testers, the data storage efficiency can be greatly improved, and a large amount of labor cost is saved.
