Abstract: Aiming at the problem of low correct rate and long time-consuming application of the fixed sequencing mode of alarm window in the centralized control system, an improved bubble sorting method is proposed, which improves the traditional bubble sorting method from the aspects of sorting method and the number of comparisons to enhance the sorting efficiency. Under the premise of ensuring the minimum change in the initial order of the alarm window, the monitoring signal automatically floats to the top layer of the interval after the action, and automatically sinks to the initial position after the return, realizing the automatic dynamic sorting of the alarm window, and effectively improving the efficiency of dynamic capture for the action signal. Finally, by comparing with the fixed sequence method, it is found that the search time of action signals can be saved up to 61.7% after the improved bubble sorting method is adopted, and the correct rate in typical application scenarios is increased to 100%, which verifies the feasibility and effectiveness of the application of the improved bubble sorting method, effectively reduces the work intensity of the monitoring personnel and comprehensively improves the dynamic perception of action signals, so as to achieve the fundamental purpose of improving quality and efficiency.
