Abstract

The invention discloses an intelligent heterogeneous sensor array of an aircraft sheath, and belongs to the sensor field. The sensor array comprises a secondary array sensor group and a primary arraysensor group, the secondary array sensor group replaces any main sensor unit in an M*N sensor group to form the heterogeneous sensor array, and the secondary array sensor group is composed of secondary sensor units in M' rows and N' columns; the M*N sensor group is composed main sensor units in M rows and N columns; and the primary sensor group is formed by residual sensor units, except the main sensor unit replaced by the secondary array sensor group, of the M*N sensor group. The sensor array layout is optimized, a small number of sensors is used to obtain effective data information almost equivalent to the larger scale of homogeneous sensor array, arrangement of useless measurement points is avoided, function expansion in a larger area is easy to realize, and the sensor array can be integrated into the aircraft sheath.

Description

technical field [0001] The invention belongs to the field of sensors, and more specifically relates to an aircraft intelligent skin non-uniform sensor array, a preparation method thereof and an acquisition system comprising the same. Background technique [0002] The main purpose of aircraft smart skin is to monitor the health of the aircraft structure, which is to use the embedded or surface-attached sensor network as the nervous system to perceive the internal state of the structure in a biological way, the overall deformation of the structure, local stress and strain, strength, Stiffness and other data information. At present, the commonly used distributed sensing measurement technology includes large-area coating of sensitive materials. The most typical one is the pressure-sensitive paint lateral pressure technology developed based on the lateral pressure on the surface of the aircraft model in the wind tunnel as the main application background. Pressure-sensitive varni...
