The invention belongs to the technical field of automatic electronic detection
black box testing, and relates to an automatic
black box detection device for an
air door opening and closing position state. The main structure comprises a first side supporting plate, a second side supporting plate, a bottom plate, circuit boards, an arc surface, a test space, a
photoelectric sensor circuit, an MCU controller circuit, a data
bus communication circuit, a main control board, a power line, a connecting line, an outer cover, an outer cover door, a main controller and power supply
processing circuits,wherein the width of the circuit board is the same as the length of an arc line corresponding to a 10-degree central angle of the first side supporting plate; the power supply
processing circuit, theMCU controller circuit, the
photoelectric sensor circuit and the data
bus communication circuit on each circuit board form a detection module; and nine detection circuit modules are positioned on thearc surface parallel to the rotating direction of the side wall of the
air door, and one detection circuit module is positioned at the bottom of the
air door. The measurement range is large, the precision is high, the
design improvement efficiency is improved, the principle is scientific, the operation is convenient, safety and reliability are achieved, and the application environment is friendly.
