Domestic flight controller based on core board design and design method

Abstract

The invention provides a domestic flight controller designed based on a core board, the core board mainly comprises a DSP+FPGA main control chip, a configuration chip and a secondary power conversion circuit, the core board only leads out an interface connected with a peripheral circuit and a core board power supply interface, and a bottom board provides power for the core board and partial interface function modules. The interface and the power supply and distribution management board realize power supply conversion of the controller and other interface function modules. The flight controller can implement functions of serial port communication, a 1553B bus, GPIO, steering engine drive control, an acquisition circuit, a power supply system, equipment activation control, GPS signal acquisition, inertial measurement unit data acquisition and the like. According to the invention, a high-performance domestic DSP+FPGA main control chip architecture is selected, the operation speed and the data processing capability of the controller are improved, FPGA logic resources are fully utilized to realize the design of maximizing interface functions, the universality of the controller is greatly improved, and the controller has the characteristics of simple design, convenience in debugging, rich interface functions, autonomous and controllable development cycle and the like.

Description

technical field [0001] The invention belongs to the technical field of flight control, and in particular relates to a domestically produced flight controller based on a core board design and a design method thereof, which can be used for navigation and control of various aircraft and guided bombs. Background technique [0002] At present, the flight controllers used in my country's existing guided bombs generally adopt an integrated design method. The main control system and peripheral function interfaces are integrated together. According to different model requirements, the controller hardware design needs to be completely redesigned. At the same time, the software also needs to be based on Improvements in hardware design will lead to problems such as poor versatility of the controller, increased workload in revision design, increased difficulty in circuit debugging, and reduced production efficiency.

[0002] At present, the flight controllers used in my country's existing guided bombs generally adopt an integrated design method. The main control system and peripheral function interfaces are integrated together. According to different model requirements, the controller hardware design needs to be completely redesigned. At the same time, the software also needs to be based on The improvement of the hardware design will lead to problems such as poor versatility of the controller, increased workload of revision design, increased difficulty of circuit debugging, and reduced production efficiency.

At the same time, due to the limitation of imported components, it is difficult to guarantee the production cycle of a single machine

Does not meet the low-cost, general-purpose, self-sufficient and controllable production requirements of flight controllers
