[0094] The judgment and evaluation unit further analyzes future risks based on the emergency risk avoidance matrix. The probability determination subunit generates a new matrix by calculating the mean of the elements in the second row of the matrix, and uses its rank as the probability of severe weather in the next detection period. The risk avoidance judgment subunit decides whether to implement emergency risk avoidance measures based on the calculated probability of severe weather. When the probability exceeds the preset value, the system will control the electric roller 13 through the visual navigation and positioning module to move the monitoring system to a safe risk avoidance position. If the probability is lower than the preset value, the electric roller 13 remains stationary. This module not only enhances the monitoring system's ability to respond to sudden weather events through systematic data collection and analysis, but also effectively ensures the safe and stable operation of the monitoring system and improves the overall operational efficiency and safety.
