Abstract

The invention discloses a FOD optical detector supplementary light module and relates to the technical field of FOD optical detectors. Including a supplementary light array, and a circuit module connected to the supplementary light array; the supplementary light array includes a low beam group and a high beam group, and the circuit module includes a power supply circuit, a main control circuit and an LED drive circuit. The power supply circuit is used to supply power to the main control circuit, LED drive circuit, low beam lamp group and high beam lamp group; the LED drive circuit is used to obtain the voltage signal of the low beam lamp group and the high beam lamp group; the main control The circuit is used to receive the voltage signal sent by the LED drive circuit and perform diagnosis. The present invention uses the LED driving circuit of the circuit module to sample fault problems such as short circuit of the supplementary light, open circuit of the supplementary light, overcurrent of the supplementary light, etc., and diagnoses through a microcontroller to realize fault self-checking.

Description

technical field [0001] The invention relates to the technical field of FOD optical detectors, in particular to a supplementary light module for FOD optical detectors. Background technique [0002] FOD (Foreign Object Debris) is a foreign object that may damage aircraft and equipment on the ground of the airport runway activity area, or threaten the safety of airport staff and passengers, that is, certain foreign substances and debris that may damage aircraft or object. [0003] FOD optical detectors are generally used in hybrid detection equipment. Hybrid detection equipment includes radar detection equipment and optical detection equipment. There are two working modes: [0004] 1. Use radar detection equipment to scan and find FOD and measure its location by transmitting and receiving radio signals, and then feed back the location information to the photoelectric detection equipment. The photoelectric detection equipment uses photoelectric sensors to identify FOD, and fina...
