Abstract
The invention relates to a television-used intelligent power manager, belonging to an electric appliance in the electrician technical field. The invention is characterized in setting the infrared self-learning single-chip microcomputer of the peripheral circuit, a signal time delay drive circuit and an operation amplifier comparator of the peripheral circuit. When the infrared receiving module circuit receives the machine starting signal of the infrared remote controller, the infrared receiving circuit will output a series of coding pulses to the single-chip microcomputer, which will compare the machine starting coding information with the coding machine starting signals of the self-learning single-chip microcomputer, which will then output the high level signal to the relay switch drive circuit. After the relay picks up and connects the television power. When shuts down the machine by remote controlling, the television current and the induced current of the induction coil will quickly reduce. And after the comparison and judgment of the operational amplifier comparator integrated circuit HA17939, the low level will be outputted to the drive circuit, the relay will trip off and the television will power off. Thus, the aim of the remote control automatic switch on of the television is realized.
