Method of detecting and localizing errors in redundant primary detectors of an automation system |
摘要 |
In redundant primary detectors, the accrual of a waiting time (T) is triggered when the value of the detector signals differ. When the detector signals still differ after the expiration of the waiting time (T), either the detector whose signal has not changed is registered as defective, or, it is decided on the basis of a majority based decision of at least three detectors which of the detectors is defective.
