Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the 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 on-line supervision. At the same time, the development and maturation of image processing techniques and artificial intelligence algorithms has enabled the analysis of video content by algorithms. Based on the above technologies, the current power operation site 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 and dangerous behaviors can be judged, and once the behaviors are found, an alarm is generated immediately. 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 performed in the data center.
However, as the power operation range is continuously expanded, the operation points are more and more scattered, so that a large number of operation site monitoring tasks are generated. The intelligent video monitoring system can correspondingly generate a large amount of alarm information when processing a large amount of monitoring videos. How to intelligently evaluate and automatically process the alarm information is a key point for further improving the efficiency of the whole video monitoring system.
Based on the above, the embodiment of the invention provides an abnormality alarm evaluation and processing method and system based on field operation.
An embodiment of an abnormality alert evaluation and processing method based on a field operation according to the present invention is described in detail below.
Referring to fig. 1 and 2, the present embodiment provides an anomaly alarm evaluation and processing method based on field operation, including:
s100: and establishing an alarm information pool of the field operation, wherein the alarm information pool is used for storing all alarm information generated by single operation.
S200: acquiring the operation risks of all alarm information in an alarm information pool according to a set alarm priority processing ordering rule, wherein the alarm priority processing ordering rule comprises dividing each 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 electric power work is performed simultaneously, a video monitoring system often floods a large amount of alarm information in a short time, and the workload of processing the alarms is beyond the processing capacity of a supervisory personnel. Generally, the alarm information is only arranged according to time sequence, and alarm information with different grades and categories is mixed together, so that supervision personnel often cannot process the most serious alarm condition in the shortest time, thereby further deteriorating the safety risk and even evolving into a safety accident. Therefore, how to re-analyze and reorganize the alarm information, eliminate redundant information and classify the alarm event in class, and realizing the intelligent centralized display of the alarm is the primary problem faced in the following.
For video monitoring of an electric power operation site, the main purpose of the video monitoring is to timely discover safety risks in operation, and the video monitoring comprises two aspects: an irregular operation behavior that may pose a safety risk; one is that an event endangering personal safety has occurred. In order to more effectively help the supervisory personnel to clear the priority of the alarm processing, the embodiment sets the alarm priority processing ordering rule, including:
all alarm information which can appear in the field operation is orderly sequenced according to different alarm levels, wherein the alarm levels comprise danger, emergency, serious and general four levels;
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 alarm information with alarm levels of danger and urgency is classified as dangerous events, and severe and general alarm information is classified as non-canonical actions.
Where the dangerous event actually occurs less, but once the hazard is greatest, the alarm level is highest and requires first time processing. The system sets different color displays for various alert levels. After the alarm occurs, the system carries out visual and audible alarm prompt to the monitoring personnel, improves the processing efficiency of the alarm, distinguishes the alarm level by color and has corresponding alarm prompt tone. The alarm information of a general power field is divided as shown in the following table.
And finally, the alarm display is used for carrying out centralized display and management and control of the alarms 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 alarms.
It should be noted that, since the alarm recognition of the electric power operation site is mainly recognized by constructing a recognition model by combining a machine learning algorithm with an image processing technology. Although the recognition accuracy of the algorithm is generally high, there are few cases where false alarms and false misses occur. Therefore, verification is required when the monitoring system presents alarm information.
The on-site operation video monitoring personnel can actively check the alarms through the monitoring video related to the system review alarms, or can check the alarms which are possibly misreported after the on-site operation video monitoring personnel remotely communicate with the on-site operation video monitoring personnel. If there is indeed a system false alarm condition. The monitoring personnel can carry out alarm elimination through the false alarm elimination function of the system, and the alarm can not be recorded by the system. When a system gives out a dangerous event alarm, a video monitoring person must immediately verify; for other types of alarms, the video monitor may optionally verify.
After verification, the on-site operation video monitoring personnel selects the alarms which are preferentially processed according to the alarm grades and the risk coefficient sum among different operations. The method comprises the following steps:
and a dangerous event alarm occurs, and the operation is considered dangerous at the moment. It is necessary to immediately suspend the present operation after confirmation and immediately process the event according to the relevant emergency treatment specifications. After the dangerous event is eliminated, the alarm is eliminated in the system, but the system records the alarm and associates the operation with related operators.
A serious alarm occurs, and at this time, the operation is considered to have an irregular behavior. The operator is informed to pause the operation, and the operation is resumed after the on-site operator corrects the operation behavior which is not standardized; and meanwhile, the alarm is eliminated in the system, but the system records the alarm and associates the operation with related operators.
A general alarm occurs, and at this time, the operation is considered to have an irregular behavior. The operation is not required to be interrupted, but operators are informed to stop the operation behavior which is not standardized, and the system records the alarm and associates the operation with the operators.
In addition, if a single job has a situation that alarms occur multiple times, the present job should be considered to be aborted. The occurrence of the alarm several times indicates that the operator is not familiar with the operation safety specification, 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 perform the operation. Specifically, the accumulated job risk sum may be calculated by using a calculation formula of the job risk sum to make a judgment, where K is the accumulated job alarm number. In the present invention, if the accumulated job risk sum is greater than 10, the present job should be aborted. The calculation formula of the job risk sum is as follows:
wherein k is the number of untreated alarms occurring in the present 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 including the inquiry of current and historical alarms can be performed, and the alarm inquiry statistics and report statistics can be displayed in a graphical alarm statistics and report statistics form, so that the classification statistics of the current or historical alarms at a certain stage can be visually displayed. And the alarm inquiry statistical function should be capable of inquiring according to an operation attribution unit, wherein the operation attribution unit comprises a power supply office, a power supply station, a team and an operator.
The embodiment provides an abnormal alarm evaluation and processing method based on field operation, which realizes the carding of a large amount of redundant alarm information by intelligently evaluating the abnormal alarms of the operation field, quantifies the alarm risk sum of single operation by means of alarm classification, risk level evaluation and the like, and guides video monitoring personnel to process the priority of the alarms according to the index ordering. In addition, according to the characteristic of the abnormal alarm of the power operation site, the whole alarm processing flow is designed to form automatic alarm processing, so that the difficulty and the workload of processing alarm information by video monitoring personnel are greatly simplified, and the efficiency of a video monitoring system for power operation is improved.
