[embodiment]
See also shown in Figure 1ly, the energy-saving standby system of a kind of digital television receiver of the present invention comprises power panel, mainboard and is arranged on breaking circuit module and MCU on the mainboard.Power panel is connected with the breaking circuit module by the power supply winding displacement, and MCU is connected with the breaking circuit module, to send the STB signal to the breaking circuit module, control breaking circuit module.Wherein, power panel passes through the power supply winding displacement to main board power supply.MCU is connected with infrared receiving terminal (IR), LED display lamp, STANDBY button respectively by the IO mouth.Described breaking circuit module is controlled it by the IO mouth by MCU, when MCU receives the standby signal that infrared receiving terminal (IR) or STANDBY button send, controlling its IO mouth sends the STB signal and moves by breaking circuit, with the power supply winding displacement shutoff of power supply to main board power supply, the working power of cutting away mainboard.When MCU receives the starting-up signal that IR or STANDBY button send once more, control its STB signal and quit work by breaking circuit, recover the power supply of power supply to mainboard.
Power panel provides the 5V power supply to receive head, STANDBY button and the power supply of LED display lamp for this MCU, IR separately, this road power supply under any circumstance all will provide to guarantee that these parts can operate as normal when the standby always, the power supply rear tube IR that makes MCU can turn-off mainboard receives head, STANDBY standby button and LED display lamp, realizes the true idle function of low-power consumption.Originally execute that MCU is the low cost of a technical grade, the single-chip microcomputer of low-power consumption in the example.
Please refer to shown in Figure 2ly, the breaking circuit module mainly is made of field effect transistor and triode, executes originally that triode is the NPN triode in the example, and the field effect transistor base stage connects the collector electrode of NPN triode.The STB signal IO mouth of MCU is connected to the base stage of NPN triode in the breaking circuit module, to control the switching of this breaking circuit.When the base stage STB of NPN triode signal ends the NPN triode during for low level, at this moment, field effect transistor base stage level is a high level, this field effect transistor conducting, and power panel can be given main board power supply by the power supply winding displacement; When the base stage STB of NPN triode signal makes the conducting of NPN triode during for high level, at this moment, the field effect transistor base stage is a low level, and this field effect transistor is ended, for the power supply winding displacement of main board power supply is cut off.Wherein, adopt field effect transistor that power supply is turn-offed and can improve its response speed, and quit work or power panel is given under the situation of mainboard normal power supply at breaking circuit, power line is lower through pressure drop behind the breaking circuit.
Please refer to Fig. 1, Fig. 3, shown in Figure 4, IR divides two-way, and one the tunnel receives the IO mouth of MCU, and the CPU_IR control port is received by a NPN triode in another road.During standby, the 5V voltage of this NPN transistor base is turned off, and triode ends, and IR receives head by MCU control.And the control signal of LED display lamp and STANDBY standby button is received the IO mouth of host CPU and the IO mouth of MCU by two resistance R respectively.On the keying panel of digital television receiver, the control signal of the control signal of infrared receiving terminal (IR), LED display lamp and STANDBY standby button is received the IO mouth of MCU respectively.
