摘要
通过对计算机的过程输入、输出通道电路分析,提出了扩大量程自诊断法和相关自诊法。该方法在不需要增加任何硬件检测接口电路的基础上,即能实现对过程输入、输出通道及传感器和执行器的自诊断。实践证明该方法经济、可靠、简单、易行,可以广泛应用于计算机测量控制系统和智能仪表等。
Two self-detecting methods,named range-augment self-detection and correlation self-detection, are proposed by analyzing the circuits of both input and output channels. Then the self-diagnosis of input and output channels,sensors and actuators,can be achieved without any additional hardware of detecting interface circuits.And applications show that they are not only simple and convenient,but even more economical and reliable. They can be widely used in the computer systems of measurement and control,intellective instruments,and etc.
