Abstract
The method comprises: 1) MCU detects the voltage value of A/D conversion port after making A/D conversion; the A/D conversion port is connected to the decoder chip; 2) MCU decides if the voltage value is less than a normal value; if yes, then entering the step 3; otherwise returning to the step 1; 3) starting up the machine to execute an initialization program. The invention connects a A/D conversion port to the 8V voltage of the decode chip, which is the fastest voltage-falling place, and detects its voltage; if it is lower than normal value, then starting up the machine to execute an initialization program so as to avoid the machine down caused by fast opening or closing the machine.
Description
Technical field
The present invention relates to a kind of television set, relate in particular to a kind of control method for TV power on and off.
Background technology
Along with the raising of people's living standard, household electrical appliance with rapid changepl. never-ending changes and improvements of a great variety have been come into ordinary people family, and television set also can bring people various knowledge when fully enriching people's free life.
Yet, in the chip of the MCU of a lot of existing television sets and the one of decoding, when the user shuts down and quick turn-on the time fast, the decoded portion chip is because load is heavier, power down soon, and the power down of MCU part is slow, causes the image entanglement and MCU does not restart normal initialize routine.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the deficiency that above-mentioned prior art exists, and a kind of control method for TV power on and off is provided, and makes television set still can restart normal initialize routine when the high-speed switch machine.
For solving the problems of the technologies described above, the invention provides a kind of control method for TV power on and off, may further comprise the steps:
(1) MCU detects the magnitude of voltage after the analog/digital conversion mouth that is connected the decoded portion chip is changed, and described analog/digital conversion mouth is connected to the 8V voltage place of described decoded portion chip;
(2) whether MCU judges described magnitude of voltage less than normal value, if then enter step (2), otherwise gets back to step (1); And
(3) start the opening initialization program.
Further, also comprise step:
(4) television set re-powers and enters normal course of operation.
Further, the every 64ms of MCU detects once in the described step (1).
The present invention has following useful effect: by an analog/digital conversion mouth being connected to the fastest 8V voltage place of decoded portion chip power down, and detect its magnitude of voltage, if be lower than normal value then start the opening initialization program, cause the problem of image entanglement thereby easily crash when avoiding existing television set high-speed switch machine.
Description of drawings
Fig. 1 is the flow chart of control method for TV power on and off of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing.
Control method for TV power on and off of the present invention is by an analog/digital (A/D) conversion mouth is connected to the fastest 8V voltage place of decoded portion chip power down, and detect its magnitude of voltage, if be lower than normal value then start the opening initialization program, cause the problem of image entanglement thereby easily crash when avoiding existing television set high-speed switch machine.
Concrete flow process is as follows:
Please refer to shown in Figure 1, when the user shuts down and quick turn-on the time fast,
At this moment step 3 if just start the opening initialization program, otherwise get back to step 1;
Claims (3)
1. control method for TV power on and off may further comprise the steps:
(1) MCU detects the magnitude of voltage after the analog/digital conversion mouth that is connected the decoded portion chip is changed, and described analog/digital conversion mouth is connected to the 8V voltage place of described decoded portion chip;
(2) whether MCU judges described magnitude of voltage less than normal value, if then enter step (3), otherwise gets back to step (1); And
(3) start the opening initialization program.
2. control method for TV power on and off according to claim 1 is characterized in that: also comprise step:
(4) television set re-powers and enters normal course of operation.
3. control method for TV power on and off according to claim 1 is characterized in that: the every 64ms of MCU detects once in the described step (1).
