Detailed description of the invention
The invention provides a kind of device controlling automobile quiescent current, this device can turn off the quiescent current consumption of all control modules of car load, and can realize Based Intelligent Control.
Referring to Fig. 1 and Fig. 2, the present invention includes MCU, microprocessor U2, battery B, relay J, cond C, three-terminal shunt regulator D, the first thyristor ~ the 3rd thyristor Q1 ~ Q3, the first aerotron ~ the 5th aerotron T1 ~ T5, the first resistance ~ the 3rd resistance R1 ~ R3, the first potential device W1 and the second potential device W2.Wherein, the charge circuit of microprocessor U2, the first potential device W1, the second potential device W2, the 4th aerotron T4, the 5th aerotron T5, the second thyristor Q2, the 3rd thyristor Q3, the first resistance ~ the 3rd resistance R1 ~ R3, three-terminal shunt regulator D and cond C formation battery B.
The principle of work of charge circuit:
V+ is Vehicular accumulator cell and generator voltage, microprocessor U2 detects the terminal voltage of electrical generator by the first potential device W1, when exporting the energizing signal of the second thyristor Q2 after the generating voltage (14V) mobile generator being detected, after second thyristor Q2 conducting, the base stage of the 4th aerotron T4 becomes high level, so the 4th aerotron T4 conducting; First resistance R1, the second resistance R2, the 4th aerotron T4 form the voltage detecting circuit of battery B, adjust the resistance of the first resistance R1, the second resistance R2, the charge threshold of battery B can be set, 4th aerotron T4 turn on emitter level raises, and the dividing potential drop of the second resistance R2 reaches the unlatching threshold values of the 3rd thyristor Q3.Make the 3rd thyristor Q3 conducting, electrical generator is charged to battery B by the 3rd thyristor Q3 and the 5th aerotron T5.In Fig. 2,5th aerotron T5, three-terminal shunt regulator D, the 3rd resistance R3, the second potential device W2 form charging voltage control circuit, second potential device W2 detects battery B both end voltage, when this voltage raises, then dragged down the base tension of the 5th aerotron T5 by three-terminal shunt regulator D, when this voltage raises, then raised the base tension of the 5th aerotron T5 by three-terminal shunt regulator D, thus reach the charging valtage of stable cell B, prevent the object of overcharge or under-charge.If microprocessor U2 does not detect the voltage of mobile generator, then make the 3rd thyristor Q3 cut-off, battery B stops charging, avoids the electricity consuming Vehicular accumulator cell.
MCU(is made up of micro controller system and wireless receiving module) receive automobile remote-control key send radiofrequency signal, door lock controller U1 export unlocking signal, latch signal, judge whether vehicle enters sea-freight or long-term laying state, and the control signal of output relay J, the first thyristor Q1 and the first aerotron T1.
In Fig. 1, Vo is the output voltage of this device, connects the normal electric input pin position of each controller of car load, and when vehicle enters sea-freight or long-term laying state, the second aerotron T2 ends, and turns off the quiescent current consumption of all controllers of car load.When vehicle is normal operating condition, the second aerotron T2, the 3rd aerotron T3 form self-locking switch circuit, and the second aerotron T2 conducting, for all controllers of car load are powered.The working timing figure that vehicle enters sea-freight and long-term laying state is shown in Fig. 3; The working timing figure that vehicle removes sea-freight and long-term laying state is shown in Fig. 4.
Battery B can adopt button cell, and on period is battery consumption electricity not.Button cell as power supply both can be changed, and can charge again when car load electric energy generated is abundant to battery, reached efficiency and utilized maximization.
