Stabilized Gyrocompass is a kind of autonomous navigation equipment which can be separated from environment disturbance,and it is an important instrument for ships navigation. The microcomputer system is the center controller of the Stabilized Gyrocompass system. In this article, firstly the author introduces working principle of Stabilized Gyrocompass and the form of microcomputer system, and then two kinds of fault detection design projects for Stabilized Gyrocompass’s microcomputer system are given up in order. One design project is based on FPGA technology and another one is based on LabVIEW virtual Instrument application. The particular content of the thesis are listed as follows.
Firstly, in the thesis, the influence of earth rotation is analyzed for free gyroscope. The author offers motion track of gyroscope principal axis on Matlab simulation platform, present the strategy which can transfer free-gyro to gyrocompass used by the bottom method, at the same time the strategy is proofed working well by Matlab simulation. Based on the gyrocompass Un-damped Oscillatory Equation, the vertical-damped method is used to set up the mathematical model which can make gyroscope principal axis stabilize immediately, then the model is implemented on Matlab platform.
On the second, with a kind of torque motor parameter, moment motor mathematical model is established, so the stabilization loop math model can be established. In the thesis the author analyze the stability of the uncorrected stabilization-loop, and then Preceding adjustment and lag compensation are added on the uncorrected network to set up corrected network math model. On the Matlab simulation platform, via the analyzing of open-loop transfer function’s Bode diagrams and unit step response those are corrected whether or not, the compare result indicates the stability of the math models.
Thirdly, in this article the author illuminate the working way to the form and action and every part of function module from some kind of Stabilized Gyrocompass microcomputer system in detail, and analyses the necessity and feasibility to develop the Stabilized Gyrocompass Microcomputer Fault Detection System. According to the function and form design to the every part of microcomputer system on the basis of PC-104 bus standard, the design scheme of microcomputer fault detection system based on FPGA is established for a kind of Stabilized Gyrocompass. The software development of this scheme based on FPGA use VHDL hardware description language. The function modules those are developed inner plate include those are listed as follows. A/D sampling control module is designed for the testing of Stabilized Gyrocompass D/A Transfer Board, UART controller is designed for the testing of Stabilized Gyrocompass I/O Serial Communication Module. FIFO memorizer is designed for the testing of Stabilized Gyrocompass I/O Parallel Communication Module. Photoelectric encoder and pulse counter are designed for the testing of Stabilized Gyrocompass A/D Transfer Board. According to the address of each peripheral device assigned by PC machine, Address assigner is designed in the fault detection system. In the end of the project The author use Visual C++ software design language to develop the software of the Stabilized Gyrocompass Microcomputer Fault Detection System.
Fourthly, the author points out that virtual instruments have so many application advantages that the traditional testing instruments can’t own. Obviously the development trend is virtual instrument as a testing device will be used popularly in the future. So the author set up the Stabilized Gyrocompass Microcomputer Fault Detection System based on LabVIEW virtual instrument. Firstly, the hardware subsection on the basis of PCI Data Acquisition Card is accomplished, then the LabVIEW graphical programming language is used to engineer the software part of Fault Detection System. Eventually the design of user-menu OSD (on-screen display) is achieved.
