Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face combines and is specifically illustrating, and this utility model is expanded on further.
Embodiment one: see Fig. 2, a kind of New-type electric machine power protection system, including BA6287 motor drive ic, its pin
Foot 1 is connected to an end after sampled point AD1, sampled point AD1 are connected to the terminals 2 of connector CN6, electric capacity C1 and C2 parallel connection and is connected to
GND2, the other end is connected to stitch 2, and stitch 2 is connected to+12V power supply, and stitch 3 is connected to stitch 2, and stitch 4 is connected to LIFTING M1, pin
Foot 5 is connected to LIFTING M2, and stitch 6 is connected to+12V power supply, and stitch 7 is connected to sampled point AD2, sampled point AD2 and is connected to resistance R mono-
End, the resistance R other end is connected to the terminals 1 of connector CN6, and stitch 8 is connected to GND2.
The series connection of motor point of incoming cables one divider resistance R, equivalent resistance R2=R1+R, wherein resistance R1 is that motor coil is deposited
At less D.C. resistance, single-chip microcomputer takes voltage sample point AD1, an AD2 respectively from equivalent resistance both sides, and motor positive and inverse is not
With, single-chip microcomputer is handled it according to different AD values.Different according to motor positive and inverse, the AD value that corresponding AD mouth is adopted is input to
Single-chip microcomputer, single-chip microcomputer makes different process according to different AD values, it is achieved power supply overcurrent protection, the inspection of motor irregular working
Survey and report to the police.
It should be noted that motor is connected with circuit in accompanying drawing by terminal CN6.M1 has signal M2 no signal just to rotate forward,
M2 has the just reversion of signal M1 no signal.BA6287 motor drive ic is connected to single-chip microcomputer, and the function of single-chip microcomputer is for receiving AD sampling
Signal, and output control signal is to LIFTING M1, LIFTING M2, thus control motor and whether work.
When Fin foot high level Rin foot is low level, motor rotates forward, and AD1 mouth is sampled, AD2 mouth functional shielding；When Rin foot
Motor reversal when high level Fin foot is low level, AD2 mouth samples, AD1 mouth functional shielding, rotates and reverse and all can complete AD and adopt
Sample, handles it to abnormal state in time.Current stabilization when motor normally works, during motor rotation blockage, electric current will be very big, logical
Crossing AD sampling and change just can be detected, time abnormal, single-chip microcomputer will send signal, and allowing OUT1 or OUT2 is low level, it is achieved electricity
Source overcurrent protection, motor sends abnormal alarm, it is achieved switch can slowly close or open；When short circuit left by motor, AD sampled value is 0,
Quitting work, buzzer sends warning.
