Abstract

The invention provides a nuclear power plant water supply control system, which includes: field equipment, at least one conversion card, and a control system; at least one conversion card is connected between the field equipment and the control system, and is used to transmit data from the control system to the field equipment control signals and receive detection signals from field devices; each conversion card includes a main I / O card and a redundant I / O card; the main I / O card and redundant I / O cards are respectively connected to the field Between the equipment and the control system; when the main I / O card and the redundant I / O card are working normally, the main I / O card and the redundant I / O card will equally divide the input / output signal; When one of the I / O card or the redundant I / O card fails, the input / output value of the other I / O card is doubled. Compared with the prior art, the water supply control system of the nuclear power plant provided by the present invention has stronger stability and reliability.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, and more specifically, the invention relates to a water supply control system for nuclear power plants. Background technique [0002] High reliability is the first requirement of process control system. Redundancy technology is a technology often used in computer system reliability design, and it is one of the most effective methods to improve computer system reliability. In order to achieve the unity of high reliability and low failure rate, redundancy technology is usually used in the design and application of the control system. [0003] At present, in the control systems of most industries, redundancy technology is implemented for key components such as power supply and network, and the reliability and stability of the system are improved by using I / O (Input / Output) card redundancy, among which , I / O cards are classified according to their usage, including AI (Analog Input) car...
