Monitoring of operating processes

摘要: Apparatus for monitoring the processes of a nuclear reactor to detect off-normal operation any process and testing apparatus. The are evaluated by response their paramters, such as temperature, pressure, etc. apparatus includes pair paths or signal-processing units. Each unit facilities receiving on time-sharing basis, status binary word made up digits each indicating process, whether normal off-normal, test-signal words simulating words. test processed in succession during successive cycles. During cycle, two units receive same word. simulate both when they indicate operation. memories. memory receives word, case may be, converts received into converted memories operate non-coincidence which signals out one not identical other unit. only where originate. also elapsed-time signalling signal if it detects no predetermined time interval after cycle processing has been initiated. transmitted an evaluating determination exists.
