The invention discloses a continuous pressure measurement device for a parallel model shielding position of a hypersonic wind tunnel. The device comprises a separation test model and embedded measurement device I and a separation test model and embedded measurement device II, wherein the separation test model and embedded measurement device I is positioned at the upper part and is connected with atail supporting device of the hypersonic wind tunnel; the separation test model and embedded measurement device II is positioned at the lower part and is connected with an abdomen supporting device of the hypersonic wind tunnel; the measurement device I comprises an upper surface stage model, the lower part of the upper surface stage model is slotted, an LED light source array I and an optical probe array I are mounted in a slot, and the slot is covered with an optical glass window I; the optical detector array I is sequentially connected with a light guide arm and a scientific CCD camera; adata signal acquired by the scientific CCD camera is transmitted to a computer for processing; the measurement device II and the measurement device I are of the same structure; and measurement surfaces are coated with a pressure sensitive paint. The device is simple in structure and convenient to mount, and effectively solves a problem of large-area pressure measurement of a parallel two-stage separation model in a shielded case.
