A Flight Controller Based on Rigid-Flexible Printed Board

Abstract

The present invention is a flight controller based on a rigid-flexible printed board, comprising a rigid-flexible printed board, an internal frame, and an inertial measurement component; the rigid-flexible printed board is installed on the internal frame through fasteners On the top, a hexahedron is formed, and the inner space of the hexahedron is used to install the inertial measurement component and its base; the rigid-flexible integrated printed circuit board is composed of seven rigid boards and six flexible boards, and the seven rigid boards are used to layout each functional module circuit, including the main control board, power board, interface board, steering gear control board, steering gear drive board, activation control board, 1553B bus and power sampling board, six flexible boards realize the main control board, power board, and main control board respectively. Signal transmission between board and interface board, main control board and 1553B bus and power sampling board, main control board and steering gear control board, steering gear control board and steering gear driving board, activation control board and 1553B bus and power sampling board .

Description

technical field [0001] The invention relates to a flight controller, in particular to a flight controller based on a rigid-flexible integrated printed board, which can be used for navigation and control of various aviation guided bombs. Background technique [0002] At present, the flight controllers used in my country's existing aviation guided bombs generally adopt the mode of the main control computer, navigation system, attitude measurement control system and other stand-alone separate work. There is a large redundancy in terms of capacity and other aspects, and the consequences are low system integration, large volume and weight, and high cost. In order to realize the low-cost and miniaturized design of the aviation guided bomb, and increase the payload and energy distribution ratio of the system, an integrated optimization design requirement of reducing the size and improving the integration level is put forward for the flight controller. In the integrated design of th...

Problems solved by technology

In the integrated design of the flight controller, due to the concentration of functions, the number of circuit boards and transmission signals has increased dramatically. The traditional board indirect plug-in occupies a large area of ​​the circuit board. In order to ensure the actual use of the circuit area, the circuit board has to be increased. The size and the height of the board indirect plug-in also increase the length of the flight controller. Multiple circuit boards are connected in series through the board indirect plug-in, which increases the difficulty of circuit debugging, and the production efficiency is low. It does not meet the requirements of aviation guided bombs on the flight controller. Low cost and miniaturization requirements
