基于ISA总线的同步通信控制器

在研究某型航空通信电台的控制协议、分析电台接口关系的基础上．介绍该电台控制特点、编码协议，并根据其控制关系．研制了以仿真总线为核。的控制器，该控制器采用基于ISA总线的硬件电路．产生符合电台控制特性的控制信号。给出控制器硬件电路和原理、软件结构和主要程序流程。

Synchronization Communication controller based on ISA Bus

In this paper, a certain type radio's characteristic and coding principle are introduced, based on the search of the certain type aviation communication radio's control principle and analysis radio's interface control protocol and artificial bus. The controller was designed based on the circuit of ISA Bus, the controller send control signal according the character of radio. The controller card's circuit structure, working principle ,program structure and flew are supposed.
