用单片机实现轮机模拟器电站仿真同步表

Implementation of a single-chip based synchronous-meter used in ship power station of marine engine room simulator

用AT89C51单片机实现了船舶轮机模拟器电站系统的同步表.介绍了该同步表的硬件构成和软件编程;讨论了基于实时性能考虑时C语言主程序如何调用汇编语言;并简要介绍了PC与单片机的串行通讯.该同步表灵敏、实时性好,显示清晰、直观,在新型轮机模拟器中发挥了应有的作用.

A singlechip AT89C51 based synchronousmeter utilized in ship power station of Marine Engine Room Simulator DMS2000 is implemented. The hardware and software of the instrument is proposed and discussed in the paper. The main program with C language calling the assemble language and serial communication between the PC and the singlechip are realized considering realtime requirements of the simulator.The synchronousmeter working status in the system running demonstrates it has clear display effect, it is reliable and plays important part in the newtype marine engine room simulator.
