Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1-2, the present invention: including battery package and little the control unit, the anodal earth connection of battery package, the anodal wire that passes through the wire of battery package with be connected for the control unit ground wire, little the control unit low-grade signal passes through diode D2 and links to each other with control switch's low-grade, control switch is hexagonal three-grade switch, the high-grade diode D1 that passes through of control switch links to each other with little the high-grade signal of control unit, diode D1 links to each other with triode Q1, triode Q1 links to each other with triode Q2, triode Q2 links to each other with diode D3, diode D3 links to each other with triode Q4, triode Q4 links to each other with diode D4 and triode Q3, diode D4 and triode Q3 pass through triode Q5 and link to each other with little the control unit power supply, the device supplies power for entire system through the battery package.
The output of the micro control unit 5V is connected with a diode D3 to realize the one-way conduction function.
Diode D4 is a zener diode so that the current remains substantially constant with voltage as it varies.
The controller supplies power and is connected with diode D2, condenser C1, triode Q2, triode Q3, triode Q4 and triode Q5 respectively, and condenser C1 is 1 mu F for the device stably switches different gears.
The ground line of the micro control unit is connected with a capacitor C2, and the capacitor C2 is 100nF for charging or discharging the micro control unit.
The working principle of the utility model is that;
when the controller is powered on, the G electrode of the diode Q1 is at a low level, and the diode Q1 is not conducted; the capacitor C1 is charged by the resistor R2, and the voltage of the G-pole of the diode Q2 is gradually increased. In a period in which the voltage of the G-pole of the diode Q2 is lower than the power supply voltage, the diode Q2 is turned on; the b pole of the diode Q4 has current flowing through, and the diode Q4 is conducted; the G pole of the diode Q3 is pulled low, and the diode Q3 is conducted; the b pole of the diode Q5 has current flowing through, the diode Q5 is conducted, and the micro control unit MCU is powered. After the micro control unit MCU works, a voltage of 5V is output; when the capacitor C1 is fully charged, the voltage of the G-pole of the diode Q2 is equal to the supply voltage, and the diode Q2 is turned off. The b-pole current of the diode Q4 is provided by the micro control unit MCU so that the diode Q4 can continue to conduct. After the controller is powered on, a low gear signal or a high gear signal detected by the MCU is at a low level. The controller consumes about 60mA of current at this time if the motor is not running.
When the micro control unit MCU detects that the low gear signal or the high gear signal is at a low level, but the motor stops running for 1 minute, the micro control unit MCU stops outputting 5V; the b pole of the diode Q4 does not flow any current any more, and the diode Q4 is closed; the G electrode voltage of the diode Q3 is equal to the power supply voltage, and the diode Q3 is closed; no current flows through the b pole of the diode Q5 any more, the diode Q5 is closed, and the micro control unit MCU is powered off. The consumption circuit of the controller is only: electricity → R1 → ground, the resistance of the resistor R1 is 2M Ω, the voltage of the battery pack is generally within 36V, and therefore the current consumed by the controller is within 20 uA.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
