Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With the popularization of video monitoring technology, the safety risk supervision of electric power field operation is transited from traditional manual field supervision to video online supervision. Meanwhile, the development and maturity of image processing techniques and artificial intelligence algorithms have made it possible to analyze video content through algorithms. Based on the technologies, the current electric power operation field safety risk supervision can realize semi-automatic intelligent real-time online analysis. By carrying out image analysis on the monitoring video, whether the operator has irregular behaviors or dangerous behaviors can be judged, and an alarm is generated once the behaviors are found. Most of the technologies are integrated into an intelligent video monitoring system, videos of all monitoring points are transmitted to a data center in real time, and online analysis and processing are carried out in the data center.
However, as the electric power operation range is continuously expanded, the operation points are more and more scattered, and a large amount of operation site monitoring tasks are generated. When the intelligent video monitoring system processes the large amount of monitoring video, a large amount of alarm information is generated correspondingly. How to carry out intelligent evaluation and automatic processing on the alarm information is the key point for further improving the efficiency of the whole video monitoring system.
Based on the above, the embodiment of the invention provides an abnormal alarm evaluation and processing method and system based on field operation.
The following describes an embodiment of the abnormal alarm evaluation and processing method based on field operation according to the present invention in detail.
Referring to fig. 1 and 2, the present embodiment provides an abnormal alarm evaluation and processing method based on field operation, including:
s100: and establishing an alarm information pool for field operation, wherein the alarm information pool is used for storing all alarm information generated by single operation.
S200: and acquiring the operation risks of all the alarm information in the alarm information pool according to a set alarm priority processing sorting rule, wherein the alarm priority processing sorting rule comprises dividing each type of alarm information according to different risk degrees and setting corresponding risk coefficients, and the operation risks comprise the risk degrees and the risk coefficients of the alarm information.
When a large amount of power operation is performed simultaneously, a large amount of alarm information is often injected into the video monitoring system in a short time, and the workload for processing the alarms exceeds the processing capacity of the monitoring personnel. Usually, these alarm messages are only arranged according to a time sequence, and alarm messages with different grades and types are mixed together, so that a supervisor often cannot process the most serious alarm condition in the shortest time, thereby causing further deterioration of safety risk and even evolving into a safety accident. Therefore, how to re-analyze and re-organize the alarm information, eliminate redundant information and classify the alarm events in a grade manner, and realizing intelligent centralized alarm display is the primary problem in the present.
For video monitoring of an electric power operation site, the main purpose of the video monitoring is to timely find safety risks in the operation, and the video monitoring comprises two aspects: an irregular job behavior that may pose a security risk; one is that a personal safety-threatening event has occurred. In order to help the supervisor to clear the priority of the alarm processing more effectively, the embodiment sets an alarm priority processing ordering rule, which includes:
sequencing all alarm information which can appear in field operation according to different alarm levels, wherein the alarm levels comprise four levels of danger, emergency, serious and general;
setting corresponding risk coefficients for the alarm information of each level after sequencing, wherein the risk coefficients of the alarm information and the alarm levels are in positive correlation;
all the alarm information with dangerous and urgent alarm levels is classified into dangerous events, and serious and general alarm information is classified into irregular behaviors.
The actual occurrence of dangerous events is less, but once the harm is extremely large, the alarm level is highest, and the first time is needed for processing. The system sets different color displays for various alert levels. After the alarm occurs, the system gives an alarm prompt to the monitoring personnel in a visual and auditory way, the processing efficiency of the alarm is improved, the alarm level is distinguished by the color, and corresponding alarm prompt tones are provided. The alarm information of a general power site is classified as shown in the following table.
And finally, the alarm display carries out centralized display and management and control of the alarm by taking single operation as a unit.
S300: and evaluating the dangerous condition of the operation according to the operation risk, and processing the operation based on the dangerous condition so as to eliminate abnormal alarm.
It should be noted that, the alarm identification of the electric power operation site is mainly performed by constructing an identification model by combining a machine learning algorithm and an image processing technology. Although the recognition accuracy of the algorithm is generally high, the situations of false alarm and false alarm are few. Therefore, verification is required when alarm information occurs in the monitoring system.
The field operation video monitoring personnel can actively check and verify the alarm by looking up the monitoring video related to the alarm through the system, or check and verify the alarm which is possibly misinformed after the remote communication with the field working personnel. If there is indeed a case of a system false alarm. The monitoring personnel can carry out alarm elimination through the function of eliminating false alarm of the system, and the alarm can not be recorded by the system. When the system gives an alarm of a dangerous event, video monitoring personnel must immediately carry out verification and verification; for other types of alarms, video surveillance personnel may optionally perform verification.
After verification, on-site operation video monitoring personnel select the alarm to be processed preferentially according to the alarm grade and the risk coefficient sum among different operations. The method comprises the following specific steps:
and (4) alarming when a dangerous event occurs, and considering that the operation is dangerous at the moment. The job needs to be terminated immediately after confirmation and the event needs to be handled immediately according to relevant emergency handling regulations. After the dangerous event is eliminated, the alarm is eliminated in the system, but the system records the alarm and associates the operation and the related operators.
And when a serious alarm occurs, the operation is considered to have an irregular behavior. The operator should be informed to suspend the operation, and the operation is resumed after the field operator corrects the operation behavior which is not standardized; and simultaneously, the alarm is eliminated in the system, but the system records the alarm and associates the operation with the related operator.
And when a general alarm occurs, the operation is considered to have an irregular behavior. The operator is informed to stop the irregular operation behavior without interrupting the operation, and the system records the alarm and associates the operation with the related operator.
In addition, if there is a situation that the alarm occurs many times in a single job, it should be considered to terminate the job. The alarm generated for many times indicates that the operator is not familiar with the operation safety standard and may not have the operation capability, and the safety risk of continuing the operation is increased, so the operation should be stopped and the operator should be rearranged to operate. Specifically, the judgment may be made by calculating the cumulative job risk sum using a calculation formula of the job risk sum, where K is the cumulative job alarm number. In the present invention, if the cumulative job risk sum is greater than 10, the job should be suspended. The calculation formula of the total risk of the operation is as follows:
wherein k is the number of unprocessed alarms occurring in the operation, R i And the risk coefficient corresponding to the ith alarm information.
In addition, based on the alarm information generated by each operation, alarm inquiry statistics can be carried out, including current and historical alarm inquiry, and the alarm information can be displayed in a graph alarm statistics and report statistics mode, so that the classification statistics of current or historical alarms at a certain stage can be visually represented. And the alarm query statistic function can be used for querying according to operation attribution units, wherein the operation attribution units comprise a power supply bureau, a power supply station, a team and an operator.
The embodiment provides an abnormal alarm evaluation and processing method based on field operation, which is characterized in that intelligent evaluation is carried out on abnormal alarms in an operation field, so that a large amount of redundant alarm information is combed, the alarm risk sum of single operation is quantified through alarm classification, risk level evaluation and other means, and video monitoring personnel are guided to process the priority of the alarm according to the index sequence. In addition, according to the characteristics of abnormal alarm of the electric power operation site, the whole process of alarm processing is designed, automatic alarm processing is formed, the difficulty and the workload of video monitoring personnel for processing alarm information are greatly simplified, and the efficiency of the video monitoring system of the electric power operation is improved.
