Substation centralized visual alarm monitoring system and monitoring information alarm display method

technical field

The invention belongs to the technical field of substations, in particular to a centralized visual alarm monitoring system for a substation and a monitoring information alarm display method.

Background technique

The substation centralized monitoring system is an important technical condition for real-time monitoring of unattended substations and a safety barrier for information monitoring. Monitoring personnel can monitor the operation of substation equipment in real time through the alarm information window. The existing alarm information monitoring system has the following problems: (1) Information display is not intuitive: information is simply displayed in a list format and described in text form, which is poor intuition, cannot improve the sensitivity of information sending, and easily causes habitual information loss; (2 ) The level of information display is single, and lack of prominent display function: all information is stacked and displayed, which cannot be clearly distinguished, and cannot be highlighted for special situations that need to be focused on; (3) Poor adaptability to emergency situations: for some special For example, information is frequently sent out and cannot be effectively processed, which will cause information to be refreshed frequently, covering other information, and there are potential safety hazards; (4) It is impossible to directly reflect the timely rate of information confirmation: for monitoring work, the timely discovery and confirmation of alarm information plays an important role in safe operation. The traditional alarm information window can only simply display the confirmation time, and cannot intuitively reflect whether the information confirmation is timely.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a substation centralized visual alarm monitoring system and monitoring information alarm display method with high intuition, outstanding alarm display and obvious information feedback.

The present invention solves its technical problem and realizes by taking the following technical solutions:

A monitoring information alarm display method for a centralized visual alarm monitoring system of a substation, comprising the following steps:

Step 1. The front-end processor of the main station receives the original equipment data sent by the substation and sends it to the monitoring background of the main station;

Step 2. The monitoring background of the master station transmits the station-side data to the data analysis conversion module;

Step 3. The data analysis and conversion module analyzes and converts the station-side data, distinguishes the alarm information points that need to be highlighted according to the logic function preset by the monitoring personnel, and transmits them to the visual alarm display window; the visual alarm display window utilizes data analysis and conversion The data information points completed by the module can complete the final visual display of alarm information through the display interface of horizontal and vertical coordinates;

The concrete realization method of described step 3 is:

(1) The data analysis conversion module defines two caches: one is the alarm confirmation cache for storing all abnormal, over-limit, displacement and accident alarms of the alarm window, which is used to display the data source on the lower axis of the visual alarm display window; the other is Store the alarm window and meet the specific conditions of abnormal, over-limit and accident action reset alarm alarm action reset cache, which is used to display the data source on the upper axis of the visual alarm display window;

(2) Start the visual alarm display window and the data analysis conversion module: while the alarm window receives all historical alarms, the data analysis conversion module puts all abnormal, over-limit, displacement, and accident alarms in the alarm window in the order of alarm occurrence time Enter the alarm confirmation cache; for the abnormality, over-limit, and accident actions of the alarm window to return to the alarm, those who meet the conditions are added to the alarm action recovery cache;

(3) The data analysis and conversion module regularly traverses the action in the alarm action reset cache that has not reset the alarm. When the interval between the alarm time of the action and the current time is greater than or equal to a certain change time, the upper axis status field is changed to a timeout action. state;

(4) When the data analysis and conversion module receives a confirmation alarm of an abnormality, over-limit, displacement, and accident alarm, it searches for the corresponding alarm in the alarm confirmation buffer, and modifies the alarm confirmation status and confirmation time field after finding it;

(5) When the data analysis conversion module receives an action alarm of abnormality, limit violation, and accident alarm, it directly adds it to the alarm action recovery cache;

(6) When the data analysis and conversion module receives a reverting alarm of an abnormality, over-limit, and accident alarm, it performs corresponding processing;

(7) After the user is switched, the data analysis conversion module records the switching time;

(8) After the start time of the horizontal axis is modified in the visual alarm display window, the data analysis conversion module returns to the buffering process of the alarm action;

(9) In the lower axis of the visual alarm display window, each alarm is displayed by reading the alarm confirmation buffer; when the alarm confirmation status is unconfirmed, the alarm is displayed below the confirmation line; when the alarm confirmation status is confirmed, pass the confirmation time Domain, displayed on the coordinates corresponding to the lower axis;

(10) In the upper axis of the visual alarm display window, each alarm is displayed by reading the alarm action and returning to the cache.

In the step (2), if the action reset alarm that meets the following conditions is added to the alarm action reset cache:

① The action reset alarm is an action alarm, and the status is not reset;

②The action reset alarm is an action or reset alarm, and the time interval between the corresponding reset or action alarm is greater than or equal to a certain change time; the upper axis status field of the action alarm and reset alarm in the cache is the timeout reset state;

③The action reset alarm is an action or reset alarm, and it is a frequent alarm.

The concrete processing method of described step (6) is:

① The reset alarm is a frequent alarm: directly added to the alarm action reset cache;

②The reset alarm is not a frequent alarm, and the corresponding action alarm time interval found in the alarm action reset cache is greater than or equal to a certain change time: the reset alarm is added to the alarm action reset cache, and the reset alarm and the corresponding action alarm are on the axis status field Change to the timeout reset state, if the upper axis state field before the action alarm is the timeout action state, then cancel the timeout action state;

③The reset alarm is not a frequent alarm, and the corresponding action alarm time interval found in the alarm action recovery cache is less than a certain change time: the alarm is not added to the alarm action recovery cache, and the corresponding action alarm is deleted in the alarm action recovery cache.

The step (8) data analysis and conversion module performs the cache processing of the alarm action restoration in the following manner:

① For the action alarm whose status is not reset: if the start time is greater than the alarm time, the status field of the upper axis of the action alarm will be added with no display status; if the start time is less than or equal to the alarm time, the upper axis status field of the action alarm will be deleted Display state;

②For the action alarm and reset alarm whose upper axis status field is timeout and reset state: if the start time is greater than the alarm time of the action alarm, the upper axis status field of the action alarm and reset alarm will add a non-display state; if the start time is less than or equal to the action alarm If the alarm time of the alarm is set, the upper axis status field of the action alarm and reset alarm will be deleted and the status will not be displayed;

③For frequent alarms: if the start time is greater than the alarm time, the upper axis status field of the frequent alarms will be added with no display status; if the start time is less than or equal to the alarm time, the upper axis status domain of the frequent alarms will be deleted with no display status ; For other frequent alarms in the same group as this frequent alarm, if there is only one other frequent alarm greater than or equal to the start time, the upper axis status field of this frequent alarm will add a non-display state; if greater than or equal to the start time If the number of other frequent alarms is greater than 1, the upper axis status field of these frequent alarms will not add the non-display status;

④ For the reset alarm whose upper axis state field is the reset state of this shift: if the start time is greater than the alarm time of the reset alarm, the upper axis state field of the reset alarm will add a non-display state; if the start time is less than or equal to the alarm time of the reset alarm and If it is greater than the alarm time of the corresponding action alarm, the status field of the upper axis of the reset alarm will be deleted and not displayed; if the start time is less than or equal to the alarm time of the corresponding action alarm, it is necessary to judge the interval If it is greater than or equal to a certain change time, the axis state field of the action alarm and reset alarm will add a timeout reset state; if the time interval is less than a certain change time, the action alarm and reset alarm will add a non-display state to the axis state field.

The display logic of the upper axis of the visual alarm display window in the step (10) is:

① For the alarm that the status field of the upper axis is empty: it will not be displayed on the upper axis;

② For the alarms whose state field on the upper axis contains no display status: not displayed on the upper axis;

③For alarms whose status field on the upper axis is in the timeout action state: the corresponding type of picture is displayed on the upper axis, and a right-pointing arrow is displayed;

④ For the action alarm and reset alarm whose status field on the upper axis is the timeout reset state: the corresponding type of picture is displayed on the upper axis, and the horizontal line connecting the action alarm and the reset alarm is displayed;

⑤For the alarm whose state field on the upper axis is the return state of the class: the corresponding type of picture is displayed on the upper axis, and an arrow pointing to the left is displayed;

⑥For alarms with both overtime reset status and class reset status in the status field of the upper axis: the corresponding type of picture is displayed on the upper axis, and a horizontal line connecting the action alarm and the reset alarm is displayed;

⑦ For frequent alarms: display the corresponding type of picture on the upper axis, and display the horizontal line connecting each frequent alarm; if the status field of the upper axis of frequent alarms contains the above 6 situations, then increase the display according to the above 6 situations .

Advantage and positive effect of the present invention are:

Detailed ways

Below in conjunction with accompanying drawing, the present invention is described in further detail:

A substation centralized visual alarm monitoring system, as shown in Figure 1, includes a master station front-end processor, a master station monitoring background, a data analysis conversion module, and a visual alarm display window; the master station front-end processor receives the primary equipment uploaded by the substation And the original data of the secondary equipment is sent to the monitoring background of the main station. The data analysis and conversion module completes the analysis and conversion of the equipment information data through the data received by the monitoring background of the main station. According to the logic function preset by the monitoring personnel, the alarm information that needs to be highlighted is displayed. Points are distinguished and sent to the visual alarm display window; the visual alarm display window uses the data information points completed by the data analysis conversion module to complete the final visual display of alarm information through the display interface of the horizontal and vertical coordinates.

The data analysis and conversion module analyzes the original text information of the received equipment in real time, converts the alarm text information into corresponding different graphic points, and distinguishes the alarm information points that need to be highlighted according to the logic functions preset by the monitoring personnel, and transmits To display in the visual alarm display window, the specific functions are as follows:

(1) The alarm information received by the data analysis and conversion module has traditional alarm information categories, including abnormality, limit violation, displacement, and accident. One-to-one correspondence, accident information is converted into triangular points, abnormal information is converted into circular points, limit violation information is converted into square points, and displacement information is converted into diamond points, while black points correspond to information actions, and gray points correspond to resets.

(2) Realize the function of automatic comparison of action reset for the three types of information: abnormality, accident, and limit violation, compare the action signal of the unified alarm information within a period of time with the reset signal, and filter out the information that satisfies the following logic: The information that the action return time interval of the period exceeds the predetermined time, the leftover information of the return of this period, the information of the non-return of the action of this period, and the information of the frequent action return of this period.

(3) Automatically record the confirmation time of the monitoring personnel information, and compare it with the sending time of the information to obtain the confirmation time difference, and screen out the currently unconfirmed alarm information.

(4) For a specific period of time, automatically screen out the switch displacement information except for the capacitive reactor, and pack and compare the displacement information of the same switch in this period.

(5) Send the analyzed and converted data information to the visual alarm display window.

The visual alarm display window uses the data information points completed by the data analysis conversion module to complete the final visual display of alarm information through the display interface of the horizontal and vertical coordinates. It uses the time axis of the horizontal and vertical coordinates as the overall picture frame, and the horizontal axis of time represents The time point at which the alarm information is issued, and the time starting point of the horizontal axis can be set as required. The vertical axis of the time is divided into an upper half axis and a lower half axis. The lower half axis represents the time difference of information confirmation, and the upper half axis does not have a specific scale. Finally, all alarm information is displayed in this display window in the form of graphic points, the upper part is the highlighted display information, and the lower part is the information confirmation display. The specific functions are as follows:

(1) Use the coordinate axis model diagram as the overall framework to replace the traditional alarm list form. As shown in Figure 2, the positive direction of the abscissa represents the time point when the alarm information is issued, and the lower half of the ordinate represents the time difference from the occurrence of the information to the confirmation of the information. The coordinate axis The top half is where important information is highlighted.

(2) The start and end time of the display interface can be set arbitrarily. Generally, the shift change time is set as the start time, and the end time is not set. The interface display is updated with time, and the historical information backup function is completed at the same time.

(3) The alarm information points that meet the logic of the data analysis conversion module are displayed prominently in the upper half of the coordinate axis: the information that the action reset interval timeout in the time period is displayed with a two-point connection, and the remaining information that is restored within the time period is displayed in the corresponding The type information points are highlighted with an arrow pointing to the left, and the alarm information that has not been reset within a period of time is highlighted with a corresponding type of information point with an arrow pointing to the right, and the frequent information is displayed as dense red and green dots above the horizontal axis Display and count the number of actions.

(4) The time difference between the sending and confirmation of the alarm information is highlighted in the lower half axis of the figure. If the information is not confirmed after it is sent, the information points are displayed below the confirmation line for prominent display. After the information is confirmed, the confirmation time difference determines the position of the information point , the message that the confirmation time has expired all stays on the confirmation line.

(5) The switch displacement information screened out by the data analysis and conversion module, except for the capacitive reactor, is displayed separately, normally hidden in the upper right corner of the coordinate diagram, and can be expanded after clicking the link. From the start time of the horizontal axis coordinates in the coordinate chart to the current time, as the statistical period, the displacement information is displayed intensively, including the double number of the displacement switch, the occurrence time, the current position of the switch, and the last action time of the switch. For multiple shifts of the same switch, it can be automatically superimposed, and can be expanded after selection.

(6) For the information upload caused by the transmission work in the station, it can be suppressed artificially, and it will not be uploaded to this display window.

A monitoring information alarm display method for a centralized visual alarm monitoring system of a substation, comprising the following steps:

Step 1. The front-end processor of the main station receives the original equipment data sent by the substation and sends it to the monitoring background of the main station.

Step 2. The monitoring background of the master station transmits the station-side data to the data analysis and conversion module.

Step 3. The data analysis and conversion module analyzes and converts the station-side data, distinguishes the alarm information points that need to be highlighted according to the logic function preset by the monitoring personnel, and transmits them to the visual alarm display window; the visual alarm display window utilizes data analysis and conversion For the data information points completed by the module, the final visual display of alarm information is completed through the display interface of the horizontal and vertical coordinates. The specific processing method of this step is:

(1) The data analysis conversion module defines two caches. One cache stores all abnormalities, limit violations, displacements, and accident alarms in the alarm window. The cache is called the alarm confirmation cache, which is used to display the data source on the lower axis of the visual alarm display window. ; The other cache stores the alarm window and meets the specific conditions for abnormal, over-limit, and accident-type action reset alarms. This cache is called the alarm action reset cache, which is used to display the data source on the upper axis of the visual alarm display window. For the alarm in the alarm action reset buffer, a new field is added, which is used to indicate the state of the alarm in the upper axis. The field type is a multi-select menu, which is judged by the mask bit.

(2) Start the visual alarm display window and the data analysis conversion module. When the alarm window receives all historical alarms, the data analysis conversion module puts all abnormality, over-limit, displacement and accident alarms in the alarm window into the alarm confirmation buffer in the order of alarm occurrence time; for the abnormality, over-limit, The actions of accidents are reset to alarm, and those who meet the following conditions can be added to the alarm action reset cache:

① The alarm is an action alarm, and the status is not reset;

②The alarm is an action or reset alarm, and the interval between the corresponding reset or action alarm is greater than or equal to △T time; the upper axis state field of the action alarm and reset alarm in the cache is the timeout reset state;

③The alarm is an action or reset alarm, and it is a frequent alarm (the alarm middle layer judges whether the alarm is a frequent alarm, and points out which alarms are the same type of frequent alarm, and writes the relevant information into the alarm structure).

(3) The data analysis and conversion module regularly traverses the action in the alarm action reset cache and the action has not reset the alarm. When the interval between the alarm time of the action and the current time is greater than or equal to △T time, the upper axis status field is changed to a timeout action. state.

(4) When receiving a confirmation alarm of an abnormality, over-limit, displacement, or accident alarm, search for the corresponding alarm in the alarm confirmation buffer, and modify the confirmation status and confirmation time field of the alarm after finding it.

(5) When receiving an action alarm of abnormality, limit violation, and accident alarm, it is directly added to the alarm action recovery cache.

(6) When receiving a reset alarm of an abnormality, over-limit, or accident alarm, the following methods are used to handle it:

① The reset alarm is a frequent alarm: directly added to the alarm action reset cache;

②The reset alarm is not a frequent alarm, and the corresponding action alarm time interval found in the alarm action reset cache is greater than or equal to △T time: the alarm is added to the alarm action reset cache, and the alarm and the corresponding action alarm on the axis state field change It is the overtime reset state. If the upper axis state field before the action alarm is the overtime action state, the overtime action state will be cancelled;

③The reset alarm is not a frequent alarm, and the corresponding action alarm time interval found in the alarm action recovery cache is less than △T time: the alarm is not added to the alarm action recovery cache, and the corresponding action alarm is deleted in the alarm action recovery cache.

(7) After the user is switched, the data analysis conversion module records the switching time. When receiving a reset alarm of an abnormality, limit violation, or accident alarm, if the corresponding action alarm time found in the alarm action reset cache is before the switching time, the reset alarm will be added to the alarm action reset cache, and the upper axis status field Return to status for this class.

(8) After the start time of the horizontal axis is modified in the visual alarm display window, the data analysis conversion module has the following processing logic for the alarm action reset cache:

① For the action alarm whose status is not reset: if the start time is greater than the alarm time, the status field of the upper axis of the alarm will be added with no display status; if the start time is less than or equal to the alarm time, the status domain of the upper axis of the alarm will be deleted with no display status ;

②For the action alarm and reset alarm whose upper axis status field is timeout and reset state: if the start time is greater than the alarm time of the action alarm, the upper axis status field of the action alarm and reset alarm will add a non-display state; if the start time is less than or equal to the action alarm If the alarm time of the alarm is set, the upper axis status field of the action alarm and reset alarm will be deleted and the status will not be displayed;

③ For frequent alarms: if the start time is greater than the alarm time, the status field of the upper axis of the alarm will be added with no display status; if the start time is less than or equal to the alarm time, the status of the upper axis of the alarm will be deleted; For other frequent alarms in the same group of frequent alarms, if there is only one other frequent alarm that is greater than or equal to the start time, the upper axis status field of the alarm will add a non-display status; if the number of other frequent alarms is greater than or equal to the start time If more than 1, the status field of the upper axis of these alarms will not add no display status;

④ For the reset alarm whose status field of the upper axis is the reset status of this shift: if the start time is greater than the alarm time of the reset alarm, the status field of the upper axis of the alarm will be added with no display status; if the start time is less than or equal to the alarm time of the reset alarm and greater than The alarm time corresponding to the action alarm, the status field of the upper axis of the alarm is deleted and does not display the state; if the start time is less than or equal to the alarm time of the corresponding action alarm, it is necessary to judge the interval time between the action alarm and the reset alarm, if the interval time is greater than or equal to △T time, the action alarm and reset alarm upper axis state field will add the overtime reset state; if the interval time is less than △T time, the action alarm and reset alarm upper axis state field will add no display state.

(9) In the lower axis of the visual alarm display window, each alarm is displayed by reading the alarm confirmation cache. When the alarm confirmation status is unconfirmed, the alarm is displayed below the confirmation line; when the alarm confirmation status is confirmed, it is displayed on the corresponding coordinate of the lower axis through the confirmation time field.

(10) In the upper axis of the visual alarm display window, each alarm is displayed by reading the alarm action and returning to the cache. Depending on the state, the display effect is different. The display logic of the upper axis is as follows:

①For the alarm whose state field is empty on the upper axis (that is, the normal action has not been reset alarm): it is not displayed on the upper axis;

② For the alarms whose state field on the upper axis contains no display status: not displayed on the upper axis;

③For alarms whose status field on the upper axis is in the timeout action state: the corresponding type of picture is displayed on the upper axis, and a right-pointing arrow is displayed;

④ For the action alarm and reset alarm whose status field on the upper axis is the timeout reset state: the corresponding type of picture is displayed on the upper axis, and the horizontal line connecting the action alarm and the reset alarm is displayed;

⑤For the alarm whose state field on the upper axis is the return state of the class: the corresponding type of picture is displayed on the upper axis, and an arrow pointing to the left is displayed;

⑥For alarms with both overtime reset status and class reset status in the status field of the upper axis: the corresponding type of picture is displayed on the upper axis, and a horizontal line connecting the action alarm and the reset alarm is displayed;

⑦ For frequent alarms: display the corresponding type of picture on the upper axis, and display the horizontal line connecting each frequent alarm; if the status field of the upper axis of frequent alarms contains the above 6 situations, then increase the display according to the above 6 situations .

An example is given below. The front-end processor collects the primary and secondary device information at the station, transmits it to the monitoring background, and then transfers it to the data analysis conversion module for analysis and processing. According to the time sequence, the data analysis module receives the following text alarm information, As shown in the table below:

According to the monitoring information alarm display method of the centralized visual alarm monitoring system of the substation of claim 1, it is characterized in that: in the step (2), if the action reset alarm that meets the following conditions is added to the alarm action reset cache: ① The action reset alarm is an action alarm, and the status is not reset; ②The action reset alarm is an action or reset alarm, and the time interval between the corresponding reset or action alarm is greater than or equal to a certain change time; the upper axis status field of the action alarm and reset alarm in the cache is the timeout reset state; ③The action reset alarm is an action or reset alarm, and it is a frequent alarm. 3. according to the monitoring information alarm display method of the substation centralized visual alarm monitoring system of claim 1, it is characterized in that: the specific processing method of the step (6) is: ① The reset alarm is a frequent alarm: directly added to the alarm action reset cache; ②The reset alarm is not a frequent alarm, and the corresponding action alarm time interval found in the alarm action reset cache is greater than or equal to a certain change time: the reset alarm is added to the alarm action reset cache, and the reset alarm and the corresponding action alarm are on the axis status field Change to the timeout reset state, if the upper axis state field before the action alarm is the timeout action state, then cancel the timeout action state; ③The reset alarm is not a frequent alarm, and the corresponding action alarm time interval found in the alarm action recovery cache is less than a certain change time: the alarm is not added to the alarm action recovery cache, and the corresponding action alarm is deleted in the alarm action recovery cache. 4. according to the monitoring information alarm display method of the centralized visual alarm monitoring system of the substation of claim 1, it is characterized in that: described step (8) data analysis conversion module is carried out in the following manner to the alarm action reset cache processing: ① For the action alarm whose status is not reset: if the start time is greater than the alarm time, the status field of the upper axis of the action alarm will be added with no display status; if the start time is less than or equal to the alarm time, the upper axis status field of the action alarm will be deleted Display state; ②For the action alarm and reset alarm whose upper axis status field is timeout and reset state: if the start time is greater than the alarm time of the action alarm, the upper axis status field of the action alarm and reset alarm will add a non-display state; if the start time is less than or equal to the action alarm If the alarm time of the alarm is set, the upper axis status field of the action alarm and reset alarm will be deleted and the status will not be displayed; ③For frequent alarms: if the start time is greater than the alarm time, the upper axis status field of the frequent alarms will be added with no display status; if the start time is less than or equal to the alarm time, the upper axis status domain of the frequent alarms will be deleted with no display status ; For other frequent alarms in the same group as this frequent alarm, if there is only one other frequent alarm greater than or equal to the start time, the upper axis status field of this frequent alarm will add a non-display state; if greater than or equal to the start time If the number of other frequent alarms is greater than 1, the upper axis status field of these frequent alarms will not add the non-display status; ④ For the reset alarm whose upper axis state field is the return state of this shift: if the start time is greater than the alarm time of the reset alarm, the upper axis state field of the reset alarm will add a non-display state; if the start time is less than or equal to the alarm time of the reset alarm and If it is greater than the alarm time of the corresponding action alarm, the status field of the upper axis of the reset alarm will be deleted and not displayed; if the start time is less than or equal to the alarm time of the corresponding action alarm, it is necessary to judge the interval If it is greater than or equal to a certain change time, then the action alarm and reset alarm will add a timeout reset state to the upper axis state field; if the time interval is less than a certain change time, then the action alarm and reset alarm will add a non-display state to the upper axis state field. 5. According to the monitoring information alarm display method of the centralized visual alarm monitoring system of the substation according to claim 1, it is characterized in that: the display logic of the upper axis of the visual alarm display window in the step (10) is: ① For the alarm that the status field of the upper axis is empty: it will not be displayed on the upper axis; ② For the alarms whose state field on the upper axis contains no display status: not displayed on the upper axis; ③For alarms whose status field on the upper axis is in the timeout action state: the corresponding type of picture is displayed on the upper axis, and a right-pointing arrow is displayed; ④ For the action alarm and reset alarm whose status field on the upper axis is the timeout reset state: the corresponding type of picture is displayed on the upper axis, and the horizontal line connecting the action alarm and the reset alarm is displayed; ⑤For the alarm whose state field on the upper axis is the return state of the class: the corresponding type of picture is displayed on the upper axis, and an arrow pointing to the left is displayed; ⑥For alarms with both overtime reset status and class reset status in the status field of the upper axis: the corresponding type of picture is displayed on the upper axis, and a horizontal line connecting the action alarm and the reset alarm is displayed; ⑦ For frequent alarms: display the corresponding type of picture on the upper axis, and display the horizontal line connecting each frequent alarm; if the status field of the upper axis of frequent alarms contains the above 6 situations, then increase the display according to the above 6 situations .
