Problems solved by technology

After the data center receives repeated alarms, the comparative analysis method adopted for these repeated alarms, the existing comparison method is generally manual comparison, which increases the workload of comparison and increases the workload; in addition, there is traditional image comparison, that is, the image features are similar However, this method produces large errors, and it cannot evaluate the trend of defect changes to guide production

Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 and figure 2 As shown, the process and algorithm of a method for analyzing repeated alarms of railway power supply detection based on image segmentation, the specific steps are as follows:

[0024] a. Extract the alarm picture from the alarm information;

[0025] b. Identify the alarm pictures;

[0026] c. Obtain the identification alarm target type and alarm target pixel size;

[0027] d. Alarms based on the same location and the same target in the data center are considered to be repeated alarms.

[0028] Said step b comprises the following sub-steps:

[0029] S1. Perform ResNet-101 layer convolution on the alarm image to obtain the alarm image features;

[0030] S2. The ROI area is obtain...

Abstract

The invention discloses a railway power supply detection repeated alarm analysis method based on image segmentation. The method comprises: carrying out comparative analysis on alarms sent by differentdetection devices or the same detection device at different time at the same position by adopting a comparative analysis method to find out the same defect at the same position, and obtaining a change trend corresponding to the defect according to the change of the defect size; According to the comparative analysis method, an image segmentation method is adopted to perform comparative analysis onalarm images collected by equipment, and the change condition of the same alarm along with time in repeated alarms is obtained. According to the alarm analysis method, safety production serves as guidance, meanwhile, a GIS map is combined, repeated alarm analysis is conducted on one line, the position where problems frequently occur on the line can be analyzed easily, and the health state of thewhole line can be known.

Description

technical field [0001] The invention relates to the field of railway power supply safety production, in particular to an image segmentation-based method for analyzing repeated alarms for railway power supply detection. Background technique [0002] For railway power supply detection, for the same defect at the same location, different motor cars or locomotives (installed with power supply detection equipment, such as 3C equipment) pass through this location to detect the defect and send an alarm message with pictures to the data center, or the same motor car Or the locomotive will send the same alarm information to the data center when it passes through the location in different time periods, which is called repeated alarm. After the data center receives repeated alarms, the comparative analysis method adopted for these repeated alarms, the existing comparison method is generally manual comparison, which increases the workload of comparison and increases the workload; in add...
