硬件在环船舶模拟器的设计与实现

Design and Implementation of Hardware in Loop Ship Simulator

针对在船舶电子设备开发过程中缺乏船舶模拟对象和船用标准信号的问题,设计了硬件在环船舶模拟器。选用ARM单片机LM3S1958作为模拟器的主控芯片,详细设计了舵角测量电路、通信接口电路和步进电罗经输出电路,分别给出了系统数据流图、主程序框图和主要软件算法。该模拟器可以模拟不同类型的船舶运行状况,输出电罗经、舵角和GPS标准信号,产生阶跃和正弦等扰动信号。该模拟器已成功应用于航向控制器和复示器等船舶电子设备的开发过程中。

Aiming at the problem of lacking ship simulation object and marine standard signal in development process of ship electronic equipment, the hardware in loop （HIL） ship simulator is designed. The ARM SCM LM3S1958 is selected as the main control chip, the design ideas for rudder angle measurement circuit, communication interface circuit and output circuit of gyrocompass are introduced in detail, and the data flow of the system, block diagram of the main program as well as the main software algorithms are given. This simulator can emulate operational state of different types of ships, as well as output standard signals of gyrocompass, rudder angle and GPS, and also create step and sine disturbing signals. The simulator has been successfully applied in the development process of ship electronic equipment, e. g. , steering controller and repeater, etc.
