The invention provides a grounding method and device for an electrical circuit interconnection system of an unmanned helicopter. The method comprises the steps of S1, receiving a grounding instruction input by a user, wherein the grounding instruction comprises a grounding end of the airborne equipment to be grounded and a grounding point to be connected; S2, detecting whether the state of the to-be-connected grounding point is unconnected or not, and whether the to-be-connected grounding point is matched with the to-be-grounded airborne equipment or not; and S3, when the state of the to-be-connected grounding point is unconnected and the to-be-connected grounding point is matched with the to-be-grounded airborne equipment, connecting the grounding end of the to-be-grounded airborne equipment with the to-be-connected grounding point, and modifying the state of the to-be-connected grounding point to be connected; otherwise, generating refit and increase information, wherein the refit and increase information comprises the information of the grounding point, and the refit and increase information is used for indicating to increase the grounding point. The problems of disordered management and difficult maintenance of the existing grounding design are solved.
Description
technical field [0001] The invention belongs to the field of helicopter grounding design, and relates to a grounding method and device for an unmanned helicopter electric circuit interconnection system. Background technique [0002] Grounding design is a very important design link in the design of the helicopter electrical circuit interconnection system. Multiple designers of the various avionics systems of the helicopter need to design the grounding for the power supply on the helicopter and multiple electrical equipment in each avionics system. [0003] With the development of helicopter avionics, the requirements for electromagnetic interference and signal interference are getting higher and higher. Especially with the development of drones and other aircraft, the cable network density is extremely high, and the grounding design of the electrical circuit interconnection system is extremely important. At the same time, the workload of grounding design also increases corres...
