船舶电站仿真系统接口技术

I/O接口是仿真系统中计算机和模拟船舶电站发电装置之间信息交换的部件 ,它使两者之间能很好地协同工作 ,每一个外设都要通过接口电路才能和主机相连。外部设备是依实际需求而不一样的 ,因而必须用各种不同的输入 /输出接口来实现计算机与外部设备之间信号的匹配和转换 ,并提供缓冲和协调控制。这里主要介绍仿真系统接口的电路结构、作用、寄存器格式 ,以及如何利用API函数编制接口界面程序。

Interface Technology for Marine Power Station Simulator

The I/O interface circuit, as an information exchanging device, coordinates the work between the computer and the simulator. Each out equipment gains access to the computer through interface circuit. Since out equipment is varied in terms of its practical need, different type of I/O circuit is required for different need of signal coupling, signal converting, data buffering and coordinate controlling. This essay mainly deals with the interface circuit configuration, functions, register format and programming of the interface code by API functions.
