The invention belongs to the technical field of information, and particularly relates to a nuclear power plant software alarm system based on high-speed serial communication.
Background
With the improvement of the requirements of the nuclear power station on the software alarm system, the current system for alarming and displaying the alarm by the indicator lamp of the nuclear power station cannot meet the current requirements, and the problems of the system are as follows: 1. only a limited number of alarm information are displayed on each side of the system, the alarms displayed on the display are all the alarms which occur recently, and the alarms which occur earlier are covered along with the generation of new alarms; 2. if no new alarm is generated, the information that the alarm is restored to be normal is still displayed on the display, and occupies the position displayed on the display, so that unnecessary interference is caused to the attention of a refueling operator to the alarm information. The problems of historical alarm information persistence and timely alarm information clearing in the prior art of a nuclear power plant software alarm system are not yet solved effectively. Therefore, the design of the nuclear power plant software alarm system with multiple functions and based on high-speed serial communication has a great application prospect.
