the historical information interface provides an alarm query function, and required alarm information can be queried from a database through alarm time, alarm sequence number, query content, alarm state, alarm sound, alarm level and alarm category; the alarm time inquiry inquires all historical information in the time period by setting the starting time and the ending time of the alarm information, wherein the ending time is defaulted as the current time, and the starting time is defaulted as the time of reversing 2 days from the current time; the grade of the alarm information is divided into 5 types: safety alarm, primary alarm, secondary alarm, out-of-sync alarm, NO CRT alarm; the alarm information categories are divided into 4 categories: oil, heavy water, compressed air, a shield door and a bridge system; power supply, A/I, D/I synchronous alarm; new fuel delivery; spent fuel transfer; the user can automatically export file setting according to requirements, and the timed export is divided into three types: deriving the timing daily (deriving historical information for a day), deriving the timing weekly (deriving historical information for a week), deriving the timing monthly (deriving historical information for a month);
(4) important alarm management:
the system provides an important alarm management function, and the function can be operated only by a user with operation authority, for example, an administrator account and a common account both have operation authority; all kinds of alarm information are listed in the important alarm management, and in addition, a user can also modify, add and delete the alarm information; the details of the alarm information are as follows: presence or absence of an alarm sound: the alarm serial number is set to be red; no alarm sound exists, and the alarm serial number is set to be white; alarm level: safety alarm, wherein the color of the alarm state is red; mainly giving an alarm, wherein the color of the alarm state is yellow; secondary alarm, wherein the color of the alarm state is blue green; NO CRT alarm, alarm state color is light blue; alarm category: oil, heavy water, air pressure, a shield door and a bridge system, wherein the color of the alarm content is blue-green; the power supply and A/I, D/I synchronous alarm are carried out, and the color of the alarm content is white; transmitting new fuel, wherein the color of the alarm content is green; spent fuel is transmitted, and the color of the alarm content is yellow;
(5) account management:
the account management has the functions of a common user information table, a registered user, a common user password modification and an administrator password modification; the common user information table is used for displaying all common accounts, and lists the information of all common accounts, including user name ID, user name, user group, user description, creation time and final modification time, wherein the user description can be null;
(6) database management:
the database management function is only operable by users with operation authority, for example, an administrator account and a common account both have operation authority, and the database management can manually backup and cut the database so as to prevent the corresponding efficiency of software from being influenced by overlarge database files.
