A cable-free electrical system for micro-integrated aircraft

Abstract

The invention relates to a no-cable electrical system of a micro integrated aircraft. The no-cable electrical system comprises a core processing unit, a sensor system, a sensor, a performing mechanism and a wireless ad hoc network, wherein the core processing unit is a task management and information processing core of the electrical system of the aircraft, and is in charge of flight control, track planning, positioning resolving, electrical control, remote-control remote-measuring and full-system resource management; the sensor system carries out relevant information sensing, acquisition and transmission on the aircraft in a wireless mode; an inertia unit in the sensor and a circuit part of a rate gyroscope are separated from the device part; a servo mechanism in the performing mechanism is integrated with a servo mechanism driver; the wireless ad hoc network adopts a time division multiplexing time trigger scheduling mechanism to carry out high-speed transmission of wireless data, so that data transmission service is provided with smallest shake and controllable time delay among nodes, high-speed real-time conflict-free data transmission is guaranteed, a space utilization rate of the aircraft is remarkably increased, and general-assembly general-measuring efficiency is improved.

Description

technical field [0001] The invention relates to an aircraft electrical system, in particular to a cable-free electrical system for a micro-integrated aircraft. Background technique [0002] The internal space of aerospace vehicles is small. In the design of aircraft at home and abroad, they are faced with the contradiction between the complexity and reliability of the electrical system of the aircraft, and the volume and weight of the system. Due to factors such as the working environment and tasks, the reliability requirements of the aircraft electrical system are very high. Usually, the system reliability is improved by redundant design of the system stand-alone, modules, lines and other levels. One of the costs that comes with it is the number of cables. The increase in weight and weight will increase the difficulty of cable routing and layout in the narrow space of the aircraft, and it is easy to form a submerged path, which will bring difficulties to the final assembly ...

Due to factors such as the working environment and tasks, the reliability requirements of the aircraft electrical system are very high. Usually, the system reliability is improved by redundant design of the system stand-alone, modules, lines and other levels. One of the costs that comes with it is the number of cables. The increase in the weight and weight of the aircraft will increase the difficulty of cable routing and layout in the narrow space of the aircraft, and it is easy to form a submerged path, which will bring difficulties to the final assembly and overall measurement of the aircraft.
