Alarm method and system based on sound-light alarm networking communication interface protocol of nuclear power plant

Abstract

The invention relates to an alarm method and system based on a sound-light alarm networking communication interface protocol of a nuclear power plant, computer equipment and a storage medium. The method comprises the following steps: determining a networking access point for acousto-optic networking alarm in the nuclear power plant; based on a preset communication interface protocol, establishing alarm communication connection between sound-light alarm systems of nuclear power areas in different periods in the nuclear power plant through the networking access point; when at least one real-time alarm signal triggered by a regional center is detected, transmitting the real-time alarm signal to a networking access point in a photoelectric conversion form based on a preset communication interface protocol; and transmitting each real-time alarm signal to each nuclear power area through the networking access point, triggering the sound-light alarm system of each nuclear power area of the nuclear power plant to respond at the same time, and generating alarm information. With the adoption of the method, sound and light alarm systems of construction projects in different periods can be quickly, compatibly and uniformly networked.

Description

technical field [0001] The present application relates to the technical field of nuclear power plants, in particular to an alarm method and system based on a nuclear power plant acousto-optic alarm networking communication interface protocol. Background technique [0002] The sound and light alarm system of nuclear power plant is used to send out sound and light alarm signals from the emergency command center, main control room, remote shutdown station, or from the reactor building and nuclear fuel building under accident conditions, so that the nuclear power plant staff can alarm according to different sounds. Information to respond to emergencies accordingly. Under normal circumstances, the sound and light alarm system will set up consoles in the main control room of the nuclear power plant, the remote shutdown station, and the emergency command center, and set up manual alarm buttons in the reactor building and nuclear fuel building to start the sound and light alarm of t...

AI Technical Summary

Problems solved by technology

[0003] Since the sound and light alarm system is one of the emergency response measures for nuclear power plants, it is necessary to connect multiple sound and light alarm system equipment regional centers within the nuclear power plant into a unified network so that the nuclear power plant can be in step in the emergency response process, but Nuclear power projects are often constructed in stages with long intervals. The sound and light alarm system equipment in different construction periods is usually supplied by different suppliers, and the equipment of different suppliers often cannot be directly connected due to the differences in PLC control programs and communication interface protocols. Networking, leading to difficulties in the implementation process of the sound and light alarm system networking between the front and back

[0004] The existing networking method is to reserve an Ethernet interface in the sound and light alarm system of the early construction project, and provide a communication interface protocol for the equipment of the manufacturer, which needs to be developed in the subsequent system construction process, and continuous joint debugging and testing, Lead to low networking efficiency and low compatibility
