Static brake protection circuit with anti-interference capability

The utility model discloses a static brake protection circuit with an anti-interference capability. A comparison circuit is manufactured by adopting an operational amplifier; the comparison circuit comprises an operational amplifier, six resistors and three diodes. Wherein a first pin, a third pin, a third diode and a fifth resistor of the operational amplifier form a static brake protection hysteresis comparison characteristic circuit. A first pin, a third pin, a second diode and a sixth resistor of the operational amplifier form an effective hysteresis comparison characteristic circuit; thehysteresis characteristic of the static brake protection circuit is improved to correspond to the difference value between the static brake effective voltage and the static brake protection voltage. Therefore, the instantaneous speed change resistance of the static brake protection circuit is improved; under the condition that the brake system outputs static brake pressure, the capacity of resisting external vibration and
