Research On Implementation Of Sight-Stabilizing Action Control System

With the development of aeronautics, it calls an urgent demand for the downsizing of its electronic equipments. How to decrease the weight and volume of electronic equipments to the maximum is drawing increasingly attention. High performance's processor and high-density device are used to solve the problem of sight-stabilizing system of helicopter. Sight-stabilizing system is an important light-electricity system of a helicopter. It is used to day and night search, detect, trace, identify and measure object. Sight-stabilizing operation control system is an important subordinate system of sight-stabilizing system. This paper introduces the design of manipulator and interface board, which are two parts of sight-stabilizing operation control system. The function of manipulator is to gather the information of control key and transmit it. The function of interface board is to deal with logical signal.For the manipulator, we use 80C196KB single-chip to realize its function. We have finished the PCB design, appearance design and assemble it. The actual size of manipulator is 12*12*12cm3. At the same time, the software that can receive data from manipulator through COM of PC is designed with C language. With this software we can visually see the state of control key over control panel on the screen.For the interface board, we use FPGA to realize its function. We finish the design of the FPGA. VHDL programs, test bench, stimulus files as well as function simulation, logic synthesis, gate-level simulation, layout and routing and back-annotated simulation have been depicted in great length. The actual size of manipulator is 90*66mm2.We finally finish the design of manipulator and FPGA circuit, then we debug with our cooperative department and gain satisfactory resuk.
