Abstract

The invention discloses an infield detection device for a rack servo electronic box. The infield detection device is composed of a power distribution box (1), a DC 28V power source (2), a display and industrial personal computer (3), an artificial load (4), a 422 module (5), a multifunctional module (6), an adapter interface (7) and a testing and metering interface (8). According to the invention, after analyzing functional verification needs of the rack servo electronic box, corresponding verification operation and checking are performed according to different functional verification needs. Instruction transmission is performed through an upper computer for controlling movement of a motor and the artificial load. Besides, by collecting 422 signals, the state of the rack servo electronic box is recognized and a detection result is given through analysis, so that the verification and monitoring functions are achieved.

Description

technical field [0001] The invention belongs to the field of aviation ordnance, and in particular relates to a detection device for the inner field of a rack servo electronic box. Background technique [0002] In the prior art, the detection of various performance indicators of the servo electronic box of the aircraft pylon is usually carried out by directly installing and electrifying the inspection. When a fault occurs, it is difficult to confirm the fault point of the pylon servo electronic box, which restricts the development progress of the aircraft final assembly and test flight. Therefore, there is a lack of a device in the prior art to realize the test of the servo electronic box on the hanger before installation and simultaneously perform fault location. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and provides a hanger servo electronic box internal field detection device, according to the performance requi...
