secondary alarming; the auxiliary equipment is not damaged and the system can not run in a short time due to the tripping of the auxiliary equipment or the abnormal parameters

Three-level alarming; parameter abnormality belongs to deviation from normal operation range, and continuous development can cause equipment damage and system abnormality

Four-stage alarming; and (4) prompting high and low limits when the parameter change exceeds the normal operation parameter range during the normal operation of the group.

The first three-level alarm system displays and prompts in the light character board through different colors, the fourth-level alarm system does not display the light character board, and the fourth-level alarm information is displayed and prompts in sound through different colors in the alarm column. The measuring point parameters related to all the alarm information are preferably displayed in red on a related picture in the DCS.

Primary alarm information: light word-red; alarm column-red

Secondary alarm information: light word-yellow; alarm fence-yellow

And (3) tertiary alarm information: light word-blue; alarm fence-blue

Four-stage alarm information: alarm column-grey.

The light character plate is gray when normal, when alarm occurs, the light character plate and the alarm column display different colors according to different levels and flash, and simultaneously sound alarm is accompanied, wherein the colors can be replaced by other colors.

The first-level alarm system, the second-level alarm system and the third-level alarm system are displayed in the light character plate through different colors, the fourth-level alarm system is not displayed in the light character plate, and all the fourth-level alarm information is displayed in the alarm column through different colors.

The main equipment tripping alarm is a primary alarm, the primary alarm is displayed on the upper part of the alarm picture of the light character plate, and each light character plate is displayed as alarm information.

The auxiliary trip alarm is classified according to the importance degree of the trip equipment, preferably, the auxiliary trip alarm is set to be three levels, the alarm levels are displayed on the middle upper portion of an alarm picture of the light character plate and are distinguished through red, yellow and blue, and each light character plate is displayed as alarm information.

The parameter abnormity alarm is divided into a plurality of levels of alarm according to different parameter properties and severity, and four levels are preferably set; the first, second and third levels of alarm are displayed at the middle and lower parts of the light character plate, the alarm levels are distinguished through red, yellow and blue, each light character plate represents the abnormal phenomenon of one parameter, and the alarms of different levels of the parameters are distinguished through displaying different colors by the same light character plate. For example:

A. light word information: the abnormal main steam temperature shows red flicker to indicate that the main steam temperature is three high values or three low values

B. Light word information: the abnormal main steam temperature shows yellow flicker to indicate the high binary value or the low binary value of the main steam temperature

C. Light word information: the main steam temperature anomaly shows blue flicker indicating that the main steam temperature is one value higher or one value lower.

The automatic mode quit alarm (including DCS soft and hardware alarm) is classified according to the influence degree of automatic control on the system, preferably three levels are set, the alarm levels are displayed on the lower portion of the alarm picture of the light character plate, the alarm levels are distinguished through red, yellow and blue, and each light character plate is displayed as alarm information.

When the parameter jumps and returns to normal, the light character board flashes in gray and gives an alarm by sound, when the operator confirms that the fixed gray is returned, the alarm column gives an alarm in a colorless state, and the alarm disappears after the alarm is confirmed.

When the operator does not perform alarm confirmation and the alarm information is not eliminated all the time, the light character plate flickers with colors at all times, meanwhile, the sound alarm continues, and if the grade of the alarm information changes in the period, the alarm information is displayed according to the color of the highest grade; when the alarm of the operator is confirmed, the light character plate is displayed in a fixed color, the sound alarm is stopped, and if the level of the alarm information changes in the period, the alarm information is displayed according to the color of the highest level; when the alarm information is eliminated, no matter whether the operator performs alarm confirmation, the light character plate is displayed in gray, meanwhile, the sound alarm is stopped, the operator does not perform alarm confirmation and determines the alarm to be in gray flashing, and the alarm confirmation is performed to be in fixed gray (only the alarm confirmation is reserved by the sound cancellation confirmation button).

All alarm information needs to be displayed in the alarm column, when no alarm exists normally, no information needs to be displayed in the alarm column, when the alarm occurs, the alarm column pops up the alarm information, different levels of alarms are represented through different colors, and the alarm category is marked at the front end of the alarm information. (for example: alarm information: tripping of auxiliary equipment: #11 sealed oil pump tripping) if the alarm information level changes, the alarm information is displayed according to the color of the highest level. When the alarm information is eliminated or the parameters are recovered to be normal, the color of the information of the alarm column disappears, operators can confirm the alarm one by one, the alarm information disappears after confirmation, and the blank state of the alarm column is recovered. For example: alarm information: and (4) alarming for parameter abnormity: and #1 unit main steam temperature abnormity alarm. After adjustment, alarm information: and (4) alarming for parameter abnormity: the #1 unit main steam temperature abnormity alarm, after readjustment, alarm parameter recovery normal range parameter abnormity alarm: and #1 unit main steam temperature abnormity alarm.

If the alarm information in the alarm column is not cleared or cannot be confirmed before being restored to the normal range, the alarm information can be remained in the alarm column. The reason needs to be found out aiming at equipment tripping or important alarm information, and the information in the light character board or the alarm column can be eliminated by resetting the operator after the commissioning is normal. In the process of combing the alarm information, it is required to note which alarms are important alarms, and the alarms can be confirmed (prompt for operators) after the operators confirm the reason or trial run is normal.

When an alarm occurs, the alarm is directly jumped into the corresponding flow chart picture through the light character board or the alarm column, and related parameters corresponding to the alarm are highlighted in color in the picture, so that operators can conveniently and immediately perform adjustment operation.

When the alarm occurs, the alarm information is screened, unimportant alarms are removed, a hierarchical alarm form is adopted, the alarms of the same type are brought into an optical character board, and the alarms of the previous level are not combined.

For example: the method comprises the following steps of steam engine alarming, circulating water pump temperature abnormity alarming, circulating water pump upper bearing temperature alarming, circulating water pump lower bearing temperature alarming and circulating water pump thrust bearing alarming.

When an alarm occurs, the light character cards corresponding to the first layer, the second layer and the third layer flicker in color and give an alarm in sound, when an operator does not confirm the alarm and the alarm information is not eliminated all the time, the light character cards in the three layers flicker in color, and the sound alarm continues, and during the period, if the level of the alarm information changes, the light character cards are displayed according to the color of the highest level; after the alarm confirmation is carried out by the operator, the three layers of light character boards are displayed in fixed colors, the sound alarm is stopped, and in the period, if the level of the alarm information changes, the alarm information is displayed according to the color of the highest level; when the alarm information is eliminated, no matter whether the operator performs alarm confirmation, the three layers of light character boards are displayed in gray, meanwhile, the sound alarm is stopped, the operator does not perform alarm confirmation, the three layers of light character boards flash in gray for alarm confirmation, and the three layers of light character boards are in fixed gray.

The sound alarms of the two different units #1 and #2 and the desulfurization system are independently separated and are respectively set up in the unit #1, the unit #2 and the ash removal operator station, the alarms are conveniently distinguished through three different sounds, and the alarm grade is distinguished through the sound intensity or frequency.
