Abstract
The utility model relates to a balance anti-interference self-correction circuit, which comprises a central microprocessor 1, a signal locking circuit A 2, a negative and gate control circuit 3, an integration circuit 4, an underweight contact switch 5, an overweight mechanism 6, an overweight contact switch 7, a pull-up resistor 8, a motor 9 and a signal locking circuit B 10, wherein the central microprocessor 1 sends out an order, and the signal locking circuit A 2 and the signal locking circuit B 10 lock the order, so that under the common effect of the negative and gate control circuit 3 and the integration circuit 4, the underweight contact switch 5 stays at an opening state when the self-correction overweight mechanism inside a balance does not work; and when the central microprocessor 1 sends out an overweight order, the overweight mechanism 6 starts the motor 9 so as to execute the overweight operation. The balance self-correction anti-interference circuit effectively eliminates the shaking phenomenon of the contact, thereby greatly improving the stability of the balance.
