本文介绍了一种在车辆驾驶训练仿真器中所使用的多处理机间通信及其管理的系统。它采用ＰＣ－８０４８６微机作为主控制计算机，对各处理机所使用的公共资源进行分配与管理，基本上避免了系统死锁的发生。一理系统发生死锁，ＷａｔｃｈｄｏｇＴｉｍｅｒ对系统进行实时监控，使其从死锁中解脱，恢复正常工作。处理机间通信采用缓冲区的方式，避免了系统资源冲突的发生，并从软硬件等方面提高了系统的抗干扰能力。
This paper presents a system of multiprocessor-to-machine communication and its management used in a vehicle driving training simulator. It uses the PC-80486 microcomputer as the main control computer, which allocates and manages the public resources used by the processors and basically avoids the system deadlock. One system deadlock occurs, WatchdogTimer real-time monitoring of the system to make it free from deadlock, resume normal work. The method of handling the inter-machine communication uses a buffer, which avoids the occurrence of system resource conflicts and improves the anti-interference ability of the system from hardware and software aspects.
