Mesh etc..
Specifically, as shown in figure 4, the key circuit can include multiple button branch roads, each button branch road and master control
The input port connection of device 100, when the button on button branch road is pressed, provides different test signals respectively.
Based on identical inventive concept, there is provided a kind of television set early stage life testing method.This method is filled based on above-mentioned test
10 are put, as shown in figure 5, comprising the following steps S110~S140.
Step S110：Start timer when receiving test instruction.Test instruction can operate test device by user
When produce, produced after can also being set out according to the condition of setting.Test instruction is to proceed by television set early stage life test
Enabled instruction.After test instruction is received, test device starts to be started and carried out test program.It is wherein to start timer
One step.
Step S120：Periodically obtain the test total time that the time base based on the timer is calculated.Timing
Benchmark is set by timer, for example, it can be set to 1 second.Timer is when the time base of setting reaches, in producing
Break signal is sent to the central processing unit of main controller.The time base set according to timer, by constantly triggering interrupt signal,
Main controller can be made to carry out timing.Such as：The timer timing is sent for 1 second once to be interrupted, and the main controller controls timer
Add 1.Cumulative timing in seconds can thus be formed.
Up to the present test total time that each cycle statistics of main controller is once spent, it will be appreciated that test process.
Step S130：According to the test total time obtained, the testing procedure performed required for judging.As described above, survey
Examination can reflect test process at total time, according to the test total time spent so far, it can be determined that currently perform
Testing procedure, and the testing procedure next to be performed.
Step S140：The testing procedure performed required for calling is tested.
Further, can also include in above-mentioned steps S120：
Judge whether the timer is suspended, if so, then stopping timing, otherwise continue timing.
When timer stopping timing being suspended, test total time is constant.
Therefore, when timer is controlled by main controller to be suspended, because test total time does not become, test program is just stopped and held
OK, it is suspended equivalent to test.Therefore, the method for testing can be suspended halfway, more convenient.
Above-mentioned television set early stage life testing method, main controller include being used for the timer for providing time base, and can
The test total time being calculated based on the time base, corresponding test step is then selected and performed according to test total time
Suddenly, therefore test can be carried out automatically, be not limited to test step number.All tests can be completed disposably, improve testing efficiency.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
