Traditional cockpit control panel adopts direct analog control mode. It is hard to upgrade system or expand for its varieties of display output equipments and complex operation, cockpit control panel digitization is is the inevitable trend for cockpit development.First, development status of current cockpit control panel is handled, on the basis of topic background and significance been illustrated. To the shortage of present system, a hybrid cockpit panel controller based on analog control and digital control technology is proposed.Second, overall project design of new hybrid cockpit panel controller is given according to objective and functional requirement of hybrid cockpit panel controller, and whole frame of hardware and software are designed.Third, hardware and software design of discrete signal processing module of the controller has been completed, high-speed, precise digital control mode for those digital equipment has been realized, using techniques of digital signal processing (DSP) and programmable logic(CPLD),after analyzing characteristic of digital equipment in cockpit; To analog equipment in cockpit,for example, temperature, humidity, illumination sensors, analog signal acquisition, process, back-up, communication have been completed by ADC module of TMS320F2812, analog equipment real-time monitoring is feasible. Three typical communication interfaces are designed, ARINC429, RS-232, RS-485, adapted to the networked development of cockpit.. Information interaction of control panels, control panel with display system, and with other electronic aids in cockpit is achieved by means of these interfaces.At last, manufacture and debugging of cockpit control panel have been completed according to design above. To inspect and verify actual functions of hybrid cockpit panel controller, test results are given, assume of perfecting the hybrid controller further is proposed.
