船用平台罗经模拟器的设计

摘要

To provide available platform compass signal in marine equipment maintenance process,the implementation of platform compass simulator used for a certain marine equipment is introduced. This system takes microcontroller,FPGA and DSC modules as control centre. Microcontroller is used to realize human⁃computer interaction,FPGA is used to implement sys⁃tem logic control,and DSC is used to generate platform compass signal. The actually measured results show that this system is simple to design and can meet the requirements of the marine equipment. It can realize rough channel and refined channel com⁃pass signal simulation,whose rotating speed ratio is 1∶36.%为了在船用设备修理过程中提供可用的平台罗经信号，介绍了使用于某设备的平台罗经模拟器实现过程，该方案以单片机+FPGA+DSC模块为核心，单片机实现人机交互，FPGA实现系统逻辑控制，DSC模块生成平台罗经信号。实测表明，该方法设计简单，满足船载设备的要求，可以实现转速比为1∶36的粗精双通道罗经信号模拟。
