Abstract

The invention belongs to the technical field of nuclear power plant control. In order to solve the technical problems existing in current core temperature and water level monitoring systems with an analog controller, the invention provides a core temperature and water level monitoring device and method suitable for EOP regulation, and adopts a digital control device to replace an analog control device. The core temperature and water level monitoring device comprises a signal conditioning layer, used for receiving signals collected on a core temperature and water level site, and performing conditioning and / or isolating on the signals; a signal input and output layer, configured to receive signals input by the signal conditioning layer; a data processing layer, used for receiving signals input by the signal input and output layer and performing a threshold comparison and self-diagnosis treatment on the signals input by the signal input and output layer; and a communication layer, used for receiving signals from the data processing layer, and sending the signals processed by the data processing layer to a display layer.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant control, in particular to the technical field of nuclear power plant reactor core temperature and water level monitoring, and more specifically relates to a core temperature and water level monitoring device and method suitable for EOP regulations. Background technique [0002] The reactor core temperature and water level monitoring system is a part of the reactor protection system, which is used to collect, process and calculate the sensor signals (such as temperature, pressure, etc.) important to the safety of the nuclear reactor core, and send the calculated signals to the main control Room and other systems go to show. [0003] But in the prior art, the device that is used for the reactor core temperature water level monitoring of two loops basically adopts still analog controller, for example, analog control clip, analog indicating instrument, by controlling the analog signal with...
