Intelligent connector, aircraft, electrical circuit interconnection system and fault detection method

Abstract

Smart connector, aircraft, electrical circuit interconnection system and fault detection method. The smart connector includes: a signal generation module for generating narrow pulse signals; a connection module connected with the signal generation module for transmitting narrow pulse signals along the cable; the connection module is also used for receiving reflected narrow pulse signals fed back along the cable to form The reflected signal; the connection module is also used to reflect the narrow pulse signal transmitted along the cable connected to it; the connection module is also used to connect with external electrical equipment, the connection module supplies power for external electrical equipment, and communicates with external electrical equipment The connection module is used to transmit signals along the cable connected to it; the signal acquisition module is connected to the connection module, and the signal acquisition module is used to store the narrow pulse signal and the reflected signal received by the connection module; the power supply module is used to generate Module, signal acquisition module and connection module supply power. This kind of smart connector can generate, reflect and store signals to detect line faults.

Description

technical field [0001] The invention relates to the field of aviation electrical systems, in particular to an intelligent connector, an aircraft, an electrical circuit interconnection system and a fault detection method. Background technique [0002] The electrical line interconnection system connects various systems and equipment, covering almost all areas of the aircraft, and the number is extremely large, and the connection relationship is extremely complicated. After the aircraft wiring work is completed, due to the long-term work of the cables and the influence of the external environment, there are cable or connector failures. Including shield wear or arc faults caused by mechanical, electrical, chemical and environmental factors, as well as electromagnetic interference and other faults caused by unreasonable wiring, which affect the normal operation of the electrical system and lead to a decrease in aircraft safety. [0003] In the traditional method, the fault diagn...

Problems solved by technology

After the aircraft wiring work is completed, due to the long-term work of the cables and the influence of the external environment, there are cable or connector failures

Including shield wear or arc faults caused by mechanical, electrical, chemical and environmental factors, as well as electromagnetic interference and other faults caused by unreasonable wiring, which affect the normal operation of the electrical system and lead to a decrease in aircraft safety

[0003] In the traditional method, the fault diagnosis method of using multimeter, buzzer or indicator light to manually connect point by point, and judging the continuity of the line by observing the electric, sound or light signal is no longer suitable for the electrical line interconnection system in the large-scale civil aircraft multi-electrical system.
