Description of drawings
Below by embodiment also in conjunction with the accompanying drawings, the present invention is described in further detail:
Fig. 1 is the circuit diagram of energy-saving control circuit of the present invention.
Embodiment
Please refer to Fig. 1, the present invention relates to a kind of energy-saving control circuit, described energy-saving control circuit is used for saving the electrical source consumption as the power consumer apparatus of load.It comprises feed circuit and controller MCU.Described feed circuit comprise incoming end VDD and working end VCC.
Preferably, described energy-saving control circuit is applicable to battery power supply system.
The working end VCC of described feed circuit connects controller MCU, and provides working power for controller MCU.
Be provided with trigger circuit between described incoming end VDD and the working end VCC and cut off circuit.
Specifically, described trigger circuit comprise trigger switch SW1, are arranged on the first P-channel field-effect transistor (PEFT) pipe switch Q1 and the 2nd N channel field-effect pipe switch Q2 of feed circuit incoming end VDD and working end VCC.Described trigger switch SW1 connects the gate pole of described the 2nd N channel field-effect pipe switch Q2, and the drain electrode of described the 2nd N channel field-effect pipe switch Q2 connects the gate pole of the first P-channel field-effect transistor (PEFT) pipe switch Q1, source ground.
Specifically, described cut-out circuit comprises the 3rd N channel field-effect pipe switch Q3.The gate pole of described the 3rd N channel field-effect pipe switch Q3 links to each other with controller MCU by port START, and drain electrode connects the gate pole of the 2nd N channel field-effect pipe switch Q2, source ground.
Push trigger switch SW1, described trigger circuit conducting feed circuit are the power consumer apparatus power supply, and described controller MCU disconnects described feed circuit by the 3rd N channel field-effect pipe switch Q3 that cuts off circuit.Described controller MCU has time block (figure does not show).Described time block cut-out feed circuit time that controller MCU sets then, realize cutting off the electricity supply by the 3rd N channel field-effect pipe switch Q3 and the second P-channel field-effect transistor (PEFT) pipe switch Q2 that cuts off circuit.
Also further be provided with the testing circuit that connects controller MCU between described incoming end VDD and the working end VCC.Described testing circuit is gathered the time of described trigger switch SW1 closure, and testing result is fed back to described controller MCU, determines to cut off the parameter of feed circuit time as controller MCU.
Described testing circuit comprises the 4th N channel field-effect pipe Q4.The gate pole of described the 4th N channel field-effect pipe Q4 connects trigger switch SW1, and drain electrode outputs to voltage detecting end SW, source ground, and described voltage detecting end SW links to each other with controller MCU.
Concrete work is as follows: when trigger switch SW1 closes, the one N channel field-effect pipe switch Q1 is with conducting, the drain electrode of the one N channel field-effect pipe switch Q1 will be dragged down, this moment, the grid owing to the second P-channel field-effect transistor (PEFT) pipe switch Q2 was a low level, and made the second P-channel field-effect transistor (PEFT) pipe switch Q2 conducting.
This moment system power supply VCC=VDD-Vds, controller MCU will start working, controller MCU puts height with the 3rd N channel field-effect pipe switch Q3 grid, the 3rd N channel field-effect pipe switch Q3 conducting.
Because a N channel field-effect pipe switch Q1 has identical driving circuit with the 4th N channel field-effect pipe switch Q4, the 4th N channel field-effect pipe switch Q4 is also with conducting, and test side SW will be for low.
When trigger switch SW1 disconnects, a N channel field-effect pipe switch Q1 will end, but because the 3rd still conducting of N channel field-effect pipe switch Q3, the second P-channel field-effect transistor (PEFT) pipe switch Q2 is also with conducting, and system works on.
At this moment, owing to the 4th N channel field-effect pipe switch Q4 ends with the disconnection of trigger switch SW1, test side SW will be high level, can detect the time of trigger switch SW1 closure thus by test side SW, make system enter different mode of operations.
After system's operate as normal, by the timer timing of controller MCU, arbitrarily initialization system provides the time of power supply for the load power consumer apparatus.When timing arrives, port START is put low, thereby close the 3rd N channel field-effect pipe switch Q3, the second P-channel field-effect transistor (PEFT) pipe switch Q2, to cut off power supply fully.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
