6.故障寻检与信号指示 自动线的故障寻检与信号指示系统是自动线控制设备中必不可少的环节。它的作用是:在正常运行中通过信号指示屏随时可以观察自动线各个设备的工作状态;当发生故障时,利用故障寻检系统及时寻找发生故障的部位,查明发生故障的原因,为排除故障提供方便。随着自动线的节拍时间的缩短,不仅要求自动控制系统的工作可靠,而且对故障寻检与信号指示也提出了更高的要求。这种新的要求表现在两个方面:一方面对可能发生故障的薄弱环节进行监视,将事故防患于未然;另一方面,一旦发生故障,能够通过寻检系统将发生故障
6. Fault detection and signal indication Automatic line fault detection and signal indication system is an essential part of automatic line control equipment. Its role is: in normal operation through the signal indicator at any time to observe the working status of the automatic line of each device; when a fault occurs, the use of fault detection system to find the fault site in time to identify the cause of the failure, in order to troubleshoot to offer comfort. As the automatic line takt time shortened, not only requires the automatic control system to work reliably, but also put forward higher requirements for fault detection and signal indication. This new requirement is manifested in two ways: on the one hand, the monitoring of weak points that may occur, preventing accidents before they occur; and on the other hand, in the event of a fault, a fault can be detected by the detection system
