介绍了中频弯管自动监控系统的基本设计思想和该系统的原理。分析了该系统的结构形式，特别针对实时多任务操作系统对该监控系统性能的重要影响，以及ｉＲ－ＭＸ８６ｆｏｒＰＣ的特点进行了深入分析。对广泛流行的ＢＯＲＬＡＮＤＣ的某些函数不能重入，影响到它在多任务环境下的应用，提出了一种简洁有效的解决方法：设置专用任务集中处理不可重入函数，利用信箱机制解决同步问题。
The basic design idea and the principle of this system are introduced. The structure of the system is analyzed, especially for the real-time multi-tasking operating system on the performance of the monitoring system and iR-MX86forPC features in-depth analysis. Some functions of widely-used BORLANDC can not be re-entered, which affects its application in multi-tasking environment. A concise and effective solution is proposed: set special tasks to deal with non-reentrancy function and solve the synchronization problem by using mailbox mechanism .
