航空通信电台控制卡的设计

机载航空通信系统中的通信电台在地面维修、检查与测试时，需要提供电台工作需要的控制信号，建立电台的工作环境。在对机载航空通信系统控制关系和控制逻辑研究的基础上，采用ISA总线，研制出符合通信控制系统控制协议的控制卡，利用控制卡和控制软件，给出符合航空电台工作的串行控制信号和并行控制信号，控制电台工作状态，实现航空电台的地面控制和测试。

Design of Controller of Aviation Communications Radio

It is necessary to set up the operating condition when the airborne radio set is tested or maintained on the ground. Based on the study of the control relation and control logic, we developed the control circuit card, which satisfies the control protocol of the communication control system adopting ISA bus. Using the control circuit card and software, the series and parallel control signals can be obtained; the operating state can be controlled so that the control and test on the ground of the radio set can be realized.
