Embodiment
[0122] Example: Obtain at time point T={t 1 ,t 2 , t 3}The set of three-dimensional coordinates of several vertices of the inner part is Z={z 1 ,z 2 ,z 3 ,z 4 ,z 5 ,z 6 ,};
[0123] in time period {t 1 -t 2}, get the 1 The coordinates of the time point part are {z 11 ,z 21 ,z 31 ,z 41 ,z 51 ,z 61}={(50,40,70),(50,0,70),(100,80,70),(120,80,70),(70,0,90),(70,60,90) }, get get at t v The coordinates of the time point part are {z 1v ,z 2v ,z 3v ,z4v ,z 5v ,z 6v}={(50,40,70),(50,0,70),(100,80,70),(120,80,70),(70,0,90),(70,60,70) }, the coordinate distance between the vertices of the parts is
[0124]
[0125] Therefore, the analyzed part is static;
[0126] in time period {t 2 -t 3}, get the 1 The coordinates of the time point part are {z 11 ,z 21 ,z 31 ,z 41 ,z 51 ,z 61}={(50,40,70),(50,0,70),(100,80,70),(120,80,70),(70,0,90),(70,60,90) }, get get at t v The coordinates of the time point part are {z 1v ,z 2v ,z 3v ,z 4v ,z 5v ,z 6v}={(50,6...

The invention discloses a safety monitoring system and method for an intelligent power distribution cabinet, and relates to the technical field of power distribution cabinet control. The system includes a simulation model establishment module, a prediction positioning module, a fault probability analysis module and a data storage module; the The simulation model establishment module obtains the three-dimensional coordinate data of each part in the power distribution cabinet, and establishes a simulation model according to the three-dimensional coordinate data in the power distribution cabinet, so that simulation experiments can be performed on the virtual power distribution cabinet; the predictive positioning control module obtains the power distribution The position of the early warning signal in the cabinet, the position of the early warning signal is mapped in the virtual power distribution cabinet model, and the number of early warnings of the parts in the future time period is predicted, and the parts whose warning times are higher than the preset number are repaired; The probability analysis module obtains the status of the parts and adjacent parts, analyzes the total probability of failure of the parts, and chooses to repair or replace the parts with an early warning according to the total probability of the parts.
Description
technical field [0001] The invention relates to the technical field of power distribution cabinet control, in particular to a safety monitoring system and method for an intelligent power distribution cabinet. Background technique [0002] The power distribution cabinet is the final equipment in all power distribution systems, but it is the core of the power distribution system. The power distribution cabinet can effectively protect, monitor and control the load. The power distribution cabinet includes relays, fuses, indicating Lights, push button switches and universal transfer switches, etc.; [0003] Although the power distribution cabinet is the last-level equipment in the power distribution system, the power distribution cabinet is the system product that is most prone to damage and requires frequent maintenance. When maintenance personnel receive a failure of a part in the power distribution cabinet, they are often not able to determine the cause. It is impossible to j...
