The invention belongs to the field of aviation, and relates to an undercarriage folding and unfolding system and method with a locking state indication function. Internal components of the actuator cylinder are simplified, and the locking state is indicated through a software and hardware combination method. The system comprises an actuating cylinder (1), an electromagnetic valve (2), a first pressure sensor (3), a control computer (4) and a second pressure sensor (5), the actuating cylinder (1) is connected to the control computer (4) through an electrical circuit and is respectively connected to two interfaces of the electromagnetic valve (2) through a retracting pipeline and a releasing pipeline; another two interfaces of the electromagnetic valve (2) are connected with a pressure supply pipeline and an oil return pipeline, and the electromagnetic valve (2) is also connected to a control computer (4); one end of the first pressure sensor (3) is connected with a laying-down pipeline, and the other end is connected to the control computer (4) through an electrical circuit; one end of the second pressure sensor (5) is connected with the upper pipeline, and the other end is connected to the control computer (4) through an electrical circuit.

    本发明属于航空领域,涉及一种带上锁状态指示的起落架收放系统及方法。简化作动筒内部组件,通过软硬件结合方法指示上锁状态。本发明系统包括:作动筒(1)、电磁阀(2)、第一压力传感器(3)、控制计算机(4)和第二压力传感器(5);作动筒(1)通过电气线路连接到控制计算机(4),通过收上管路和放下管路分别连接到电磁阀(2)的两个接口;电磁阀(2)还有另外两个接口连接供压管路和回油管路,电磁阀(2)还连接到控制计算机(4);第一压力传感器(3)一端连接放下管路,另一端通过电气线路连接到控制计算机(4);第二压力传感器(5)一端连接收上管路,另一端通过电气线路连接到控制计算机(4)。
