Abstract

The invention discloses a redundant analog parameter display system for a nuclear power plant, which is used for displaying measured values of multiple redundant analogs of at least one parameter of the nuclear power plant. The redundant analog parameter display system comprises multiple analog sensors, an effective computation module and a display module, wherein the multiple analog sensors are used for measuring the multiple redundant analogs corresponding to each parameter and transmitting the measured values; the effective computation module is connected with the multiple analog sensors and used for receiving the multiple measured values and computing one effective measured result of each parameter according to the multiple measured values and transmitting the results; the display module is connected with the effective computation module and used for displaying the effective measured result of each parameter by one display icon, and the multiple measured values transmitted by the multiple analog sensors can be inquired through the display icons. Besides, the invention discloses a redundant analog parameter display method for the nuclear power plant. With adoption of the redundant analog parameter display system and method for the nuclear power plant, information in displayed images is simplified, and monitoring load of an operator is reduced.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a system and method for displaying redundant analog parameters of nuclear power plants. Background technique [0002] In nuclear power plants, the important equipment parameters of the whole plant are collected through the digital control system and displayed on the operation station in the main control room. The operator can effectively monitor the power plant through the displayed information on the operation station. In nuclear power plants, the same parameter is often measured by multiple redundant analog sensors, and according to nuclear safety requirements, all of them need to be sent to the operator station in the main control room for display. [0003] In the prior art, the operating station in the main control room of the nuclear power plant uses independent analog display icons corresponding to individual analog sensors. If there are multiple redundant anal...
