The power-off of signal control motor processed 12, stop operating.
The drive circuit of motor 12 is driven using the current-limiting mode shown in Fig. 8, and the drive circuit 8 includes four driving tubes
G1, G2, G3, G4, resistance R1, R2, electric capacity C1, C2, the function with anti-wiring short circuit is hampered, transships and the stall of motor 12 guarantor
Shield, can effectively solve the problem that：A, external cabling short circuit or motor 12 it is short-circuit when, directly damage motor 12 driving tube G1,
G2, G3, G4, and the defect of internal circuit；In b, the rotation process of door 4 meet people push away, be obstructed or mechanical breakdown cause motor 12 block up
When turning, the increase of the electric current of motor 12 causes the defect that driving tube G1, G2, G3, G4 and internal circuit are damaged in circuit；C, door 4 are rotated
During people when pushing 4, being obstructed, the high current of motor 12, high-torque output, reducing gear 13,14 bears for a long time high-torque and causes use
Service life reduction, prolonged delays cause the defect that the heating of motor 12 is damaged.
As shown in figure 8, single-chip microcomputer output control signal control PWM pulse-width modulation circuits when rotating forward, control driving tube G1, G4
Pwm control signal intermittent conduction, electric current is followed to flow through driving tube G1, motor 12, driving tube G4, current sense resistor from power supply
R1, motor 12 is rotated forward；Single-chip microcomputer output control signal control PWM pulse-width modulation circuits during reversion, control driving tube G2, G3 are followed
Pwm control signal intermittent conduction, electric current flows through driving tube G2, motor 12, driving tube G3, current sense resistor R1 from power supply,
Motor 12 is inverted；Motor is rotated and drives driving gear 13, driven gear 14, drive shaft 15 to rotate, and torque is exported from drive shaft 15,
Door 4 is transferred force to by first connecting rod 2 and second connecting rod 3, so as to realize action of opening the door or close the door.
According to Ohm's law, resistance R of the electric current I* resistance R1 flow through in the voltage U=resistance R1 at resistance R1 two ends, from
Formula can be seen that the voltage at resistance R1 two ends and be directly proportional to the electric current I flow through in resistance R1, the electric current I flow through in resistance R1
The voltage at more big then series resistance R1 two ends is higher, and this voltage filters net through the RC that electric capacity C1, resistance R2, electric capacity C2 are constituted
Single-chip microcomputer analog-digital converter is entered after network, the discernible digital quantity of single-chip microcomputer is converted to, single-chip microcomputer passes through the magnitude of voltage for detecting
Just the current value for flowing through in resistance R1 can be calculated by above-mentioned formula.
In automatic door opening or door closing procedure, the current value of single-chip microcomputer meeting motor in real time driving circuit, namely resistance
The current value flow through in R1, pushes away, is obstructed or mechanical breakdown causes motor 12 when wiring short circuit occur, people is met in the rotation process of door 4
When stall or overload, electric current will be substantially increased, and single-chip microcomputer enters this real-time current value with maximum operating currenbt value set in advance
Row compares, if real-time current value exceedes presets current value, single-chip microcomputer output control signal control PWM pulse-width modulation circuits
The ON time for reduce pulse width, allowing driving tube G1, G2, G3, G4 within the unit interval reduces, and rapidly reduces motor 12 and drives
Electric current, if be reduced to the electric current of setting, the pulse width range of decrease is larger, when reaching threshold value set in advance, and single-chip microcomputer will be exported
Control signal control driving tube G1, G2, G3, G4 disconnect, the power-off of motor 12, so as to reach the purpose of protection.
The current sense resistor R1 can be by the way of one or more resistor coupled in parallel, according to different capacity, electric current
Motor realizes the matching of resistance value and power；Driving tube G1, G2, G3, G4 can be according to different powers of motor, electric current, voltage choosings
With FET, triode or IGBT；Power supply can be matched according to the rated voltage of different motors.
The above, is only presently preferred embodiments of the present invention, not makes any limit to the technical scope of the present invention
System, therefore any trickle amendment, equivalent variations and the modification that every technical spirit according to the present invention is made to above example,
Still fall within the range of technical scheme.
