Abstract
An air-tight door system and a control method therefor. The air-tight door comprises a first door (M1), a second door (M2), a first door detection module (S1, S2, P1), a second door detection module (S3, S4, P2) and a controller (K). The air-tight door control method comprises: the first and second detection modules (S1, S2, P1, S3, S4, P2) detect whether the first door (M1) and the second door (M2) are completely closed; and the controller (K) controls opening and closing of the first door (M1) and the second door (M2) according to whether the first and second doors (M1, M2) are completely closed. The air-tight door system and the control method therefor ensure that at least one door is in the closed state at any time, thereby further improving air-tightness and device safety.
