Title:
MULTIPLE SEQUENCE SAFETY DISPLAY AND CONTROL TOUCH SCREEN SYSTEM OF NUCLEAR POWER PLANT AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/103857
Kind Code:
A1
Abstract:
Provided are a multiple sequence safety display and control touch screen system of a nuclear power plant and a control method. The system comprises a non-safety processing unit for sending a sequence invoking signal, multiple single sequence safety processing units for receiving an invoking signal, and a screen switching module for switching device state information and an operation interface of a single sequence safety processing unit of an invoked sequence under a first or second screen switching mode and locking device state information and operation interfaces of other sequences. The present invention overcomes the defects in the prior art of a low working efficiency, and the increase in an operation load and a safe running risk since each sequence safety processing unit needs to be correspondingly provided with a single sequence safety display and control touch screen. By adding a screen switching module, device state information and operation interfaces of multiple single sequence safety processing units are switched to and displayed on the same M-SDCTS, thereby optimizing the design of a digital human-machine interface of a control room of a nuclear power plant and improving the working efficiency and the safety of the running of the nuclear power plant.
