摘　　要：本文介绍了一种针对实时控制系统运行情况的检测控制装置,该装置应用了基于高频信号发生器与移位寄存器协调工作的毫秒级监测电路实现对实时系统运行情况的监视。当系统发生故障时,控制电路能够有效地驱动保护电路实施保护。该电路具有报警时间可调、响应速度快、无运行系统、纯硬件检测等优点,保证了系统的安全可靠运行。该检测装置与实时控制系统应用于油气悬架试验台实时控制系统中,使系统的安全性、可靠性得到大幅度的提高,为相关的节能降耗提供了保障。This paper introduces a kind of checking device used to monitor the running situation of a real - time control system. The new checking device uses high frequency signal generator and shift register detection circuit to ensure monitoring function. The control circuit will drive the protection circuit effectively to achieve pro- tection timely when malfunction happens. This circuit has advantages such as tunable warning time, fast response, no single running system, hardware - only testing etc. which can improve the system reliability. This device is used in the hydro - pneumatic suspension testing system to improve the system＇ s real - time safety and reliability so that the new technology presents a promising potential of the system energy saving.
