一种数字阀阵列刹车系统及控制方法

The invention provides a digital valve array braking system and a control method, wherein the digital valve array braking system comprises a boosting valve group, a pressure reducing valve group and a control system, the boosting valve group comprises a plurality of first switch valves, the plurality of first switch valves are respectively connected between a high-pressure end and a braking control end in parallel, the pressure reducing valve group comprises a plurality of second switch valves and a plurality of third switch valves, the plurality of second switch valves and the plurality of third switch valves are respectively connected between a low-pressure end and the braking control end in parallel, the flow area of the second switch valves is smaller than that of the third switch valves, the control system selectively controls at least one first switch valve to work according to the slip rate of wheels so as to boost the pressure of the braking control end, or selectively controls at least one second switch valve and/or the third switch valve to work so as to enable the braking control end to release pressure. The invention can realize rapid pressure relief when the brake pressure needs to be suddenly reduced, improves the anti-pollution capability of the aircraft brake system and improves the reliability of the aircraft brake system.
