Nuclear plant alarm display device utilizing digitized technology

Abstract

The invention relates to the technical field of nuclear planet industrial automatic control, and particularly discloses a nuclear plant alarm display device utilizing the digitized technology. A display terminal A in the alarm display device is connected with a server through a power plant instrument control system interface, and a communication interface module in the server obtains an alarm signal generated through the power plant instrument control system and sends alarm signal data to the display terminal A through the power plant instrument control system terminal. The power plant instrument control system interface is further connected with a power plant local area network through a firewall, the power plant local area network is directly connected with a display terminal B, and the power plant local area network is further connected with a display terminal C through a power plant wireless local area network so that the alarm signal data can be transmitted to the display terminal B and the display terminal C. The nuclear plant alarm display device provides various types of alarm display for operating personnel in the public area of a main control room, so that a user can obtain alarm information through various types of methods.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant industrial automation control, and in particular relates to a nuclear power plant alarm display device using digital technology. Background technique [0002] With the continuous development and progress of digital technology, nuclear power plant instrumentation and control systems have also entered the development stage of full digital technology, among which the development of human-computer interaction technology is the most prominent. As an important human-machine interface in the control room of a nuclear power plant - the alarm system, it can promptly remind the operator of changes in the operating state of the nuclear power plant or the working conditions where the operating state deviates from the requirements, so that the operator has time to take effective actions and corrections measure. At the same time, according to the requirements in nuclear safety regulations HAF102 1)...

AI Technical Summary

Problems solved by technology

However, it has the following disadvantages in practical application: 1) The display content is single and fixed, that is, each alarm point window can only correspond to one alarm signal, which is not conducive to the evaluation of the comprehensive state of the system or equipment. At the same time, in a limited control room environment It takes up a lot of space; 2) It is difficult to maintain and change. If you need to add, modify or delete an alarm window, you need to replace the alarm window; 3) Maintenance personnel need to enter the main control room of the nuclear power plant when performing replacement work, which is not conducive to nuclear power plants. The overall safety of the plant; 4) Since the physical alarm window needs to contain a large number of metal shells, brackets and plastic materials, the cost of equipment manufacturing and maintenance is higher
