In embodiments of the present invention, the operation principle of television set resetting system 100 is:
Television set is after entering normal operating condition, TV set power 200 is exported standby voltage and start voltage simultaneously, output stand-by operation voltage after standby voltage is processed by voltage treatment circuit 101, this stand-by operation voltage keeps storage capacitor C3 is charged, storage capacitor C3 can continue to export the resetting pin RST of high level reset signal to 8032 single-chip microcomputer, and the power supply signal that the general input/output port GPIO1 of 8032 single-chip microcomputers exports also can keep low level state always.Thereby make 8032 single-chip microcomputers stop reset operation after start resets, avoided the situation of repeated trigger reset operation to occur; Meanwhile, threshold voltage generation unit 102 is split electromechanics and is compressed into capable clamper and control and export a threshold voltage, this threshold voltage charges to capacitor C 1 and storage capacitor C2 respectively by diode D1 and diode D2, and due to the capacitance of the storage capacitor C2 capacitance much larger than capacitor C 1, so the charging rate of capacitor C 1 is much larger than storage capacitor C2, capacitor C 1 can be completed charging prior to storage capacitor C2.
the start voltage of exporting when TV set power 200 occurs interrupting or when falling, voltage treatment circuit 200 will export one lower than the needed start operating voltage of the normal operation of television set, thereby make the clamper combinational circuit that voltage stabilizing didoe ZD1 and resistance R 2 form to control generation one threshold voltage by clamper, so, capacitor C 1 is discharged by resistance R 3 and resistance R 4, storage capacitor C2 also begins the emitter discharge to positive-negative-positive triode Q1 subsequently, thereby make the emitter voltage of positive-negative-positive triode Q1 higher than its base voltage, positive-negative-positive triode Q1 saturation conduction is also exported a high level from its collector electrode, and then make NPN type triode Q2 and NPN type triode Q4 saturation conduction, the collector electrode of the collector electrode of NPN type triode Q2 and NPN type triode Q4 is low level, grid due to N-type metal-oxide-semiconductor MOS1 keeps high level state always again, and the base stage of NPN type triode Q3 is ended under the prerequisite of the general input/output port GPIO1 of 8032 single-chip microcomputers output low level, so N-type metal-oxide-semiconductor MOS1 conducting, storage capacitor C3 by N-type metal-oxide-semiconductor MOS1 and NPN type triode Q2 repid discharge to low level, so, 8032 single-chip microcomputers begin to enter reset mode, at this moment, because the general input/output port GPIO1 output low level of 8032 single-chip microcomputers makes NPN type triode Q5 cut-off, and the Q4 conducting of NPN type triode and its collector electrode output low level, this low level makes TV set power 200 close the start Voltage-output and enter holding state.After entering holding state, the start voltage of its output is zero due to TV set power 200, and capacitor C 1 and storage capacitor C2 continue discharge, and the collector electrode of positive-negative-positive triode Q1 continues the output high level.When capacitor C 1 and storage capacitor C2 discharge off, positive-negative-positive triode Q1 cut-off, its collector electrode output low level, NPN type triode Q2 and NPN type triode Q4 be cut-off thereupon also, so, N-type metal-oxide-semiconductor MOS1 cut-off, stand-by operation voltage begins storage capacitor C3 is charged, the just very high level of storage capacitor C3 resets thereby microprocessor 300 is completed.Along with TV set power 200 and resetting of 8032 single-chip microcomputers are completed, television set can restart normal operating conditions.
In embodiments of the present invention, when TV set power 200 the start voltage interruption occurs or falls, because reset unit 104 and power control unit 105 can make TV set power 200 and 8032 chip microcontroller parking position accuracies, so whole television set resetting system has the high characteristics of stability.Moreover television set resetting system 100 can be selected suitable voltage stabilizing didoe ZD1, capacitor C 1 and storage capacitor C2 according to the actual requirements in application process, thereby makes the applicability of whole television set resetting system 100 strong.
The embodiment of the present invention also provides a kind of television set that comprises above-mentioned television set resetting system 100.
in embodiments of the present invention, comprise threshold voltage generation unit 102 by adopting in television set, triggering signal generation unit 103, the television set resetting system 100 of reset unit 104 and power control unit 105, when the start voltage appearance of TV set power 200 is interrupted or is fallen, triggering signal generation unit 103 impels reset unit 104 control microprocessors 300 to enter reset mode, and power control unit 105 is controlled simultaneously TV set power 200 and is realized resetting, thereby solved can't resetting to TV set power that prior art exists when supply voltage occurs temporarily interrupting or falls, and stability and problem poor for applicability.
