摘要
转速控制单元是水下热动力推进系统的重要组成部分,其直接影响着动力推进系统的性能;为了实现对系统的精确控制,采用以PC104嵌入式计算机为核心,开发了系统的转速控制单元方案,给出了系统的工作原理及基本硬件组成,介绍了多周期同步计数转速测频方法、抗干扰措施、各软件模块功能及中断处理;通过数字试验台实验证明该系统具有良好的实用性和可靠性。
Rotation speed control unit is an important part of underwater heat power propeller system, it directly effects performance of power propeller system. A project of rotation speed control unit is presented, which is based on PC104 embedded computer. A work principle of system and basic hardware configurations are introduced. Measuring frequency of multi--period synchronous counting, method of anti --interference, software module function of system and interrupt handling are introduced. Dependability and practicability of system are proved by test.
