Problems solved by technology
[0002] All kinds of monitoring data in mines are an important basis for intuitively reflecting the dynamics of safe production. At present, various monitoring systems mainly store data through data integration, and realize data overrun by comparing the monitoring value with the sensor limit value of the data itself or setting the alarm limit value. Alarm, there is no relevant calculation and identification technology for the abnormal fluctuation of data within the alarm limit, and because the normal value of each sensor monitoring data is different, setting the alarm limit for a certain type of sensor to trigger the alarm is relatively extensive, and risk identification is lagging behind , it is impossible to analyze the abnormal fluctuation within the alarm limit and judge the possible risk of early warning

The invention discloses a method and device for early warning of abnormal fluctuations in mine monitoring data. Based on the mine monitoring data and abnormal fluctuation early warning index system, the invention can query historical monitoring data and calculate monitoring values of various monitoring points by connecting to a mine end monitoring and monitoring database. Fit function and normal fluctuation range, query real-time monitoring data to calculate real-time deviation, configure different early warning analysis methods to calculate the comparison value between real-time deviation and reference standard deviation, and combine the interval setting values of multi-level early warning indicators to judge whether it is an abnormal fluctuation early warning and Corresponding to the early warning level, the early warning method of abnormal fluctuations in monitoring data can win valuable time for safety risk identification, hidden danger investigation and treatment, and reduce the probability of accidents.
Description
Technical field[0001]The invention belongs to the technical field of mine safety monitoring data abnormality monitoring, in particular to an early warning method and device for abnormal fluctuations of mine monitoring data.Background technique[0002]Various monitoring data of mines are an important basis for intuitively reflecting the dynamics of safe production. At present, various monitoring systems are mainly stored in the database through data integration, and the monitoring value is compared with the sensor limit of the data itself or the alarm limit is set to achieve the data exceeding the limit. Alarm, there is no relevant calculation and identification technology for the abnormal fluctuation of data within the alarm limit, and because the normal value of the monitoring data of each sensor is different, the way to set the alarm limit for a certain type of sensor to trigger the alarm is relatively extensive, and the risk identification is relatively lagging , It is impossible t...
