Embodiment 1
[0038] Embodiment 1: see figure 1 , an intelligent inspection method for equipment in a large hydropower station, the method steps are as follows,
[0039] Step 1. According to the characteristics of large-scale hydropower station equipment, analyze the inspection equipment and determine the inspection content. According to the characteristics of large-scale hydropower station equipment, analyze the inspection equipment, including the focus of attention, normal state, abnormal state characteristics, and prone to occurrence of equipment. Defect location and defect type. For example, the joints of water supply pipes in hydropower stations are prone to water leakage and water spray defects due to loose connection bolts or aging seals at the joints; for example, during the operation of electrical equipment in hydropower stations, equipment damage due to aging or unstable voltage of components;
[0040] Step 2. According to the location of the inspection equipment and the content ...

The invention discloses an equipment intelligent inspection method for a large hydropower station, and the method comprises the following steps: 1, determining the inspection content according to theequipment characteristics of the large hydropower station; 2, determining adopted inspection equipment; 3, determining an inspection route of each inspection robot, and determining an installation position and an acquisition content; step 4, centrally uploading the data to a background server; 5, enabling the background system to perform image recognition on the images and the video streams; performing temperature identification on the infrared thermogram; carrying out characteristic quantity analysis on the sound; 6, automatically judging whether the inspection equipment is normal or not; 7,enabling the background server to send the abnormal result to the mobile phone of the user in a short message mode and give an alarm for reminding; and step 8, automatically generating an inspection report. Compared with the prior art, the visible light camera, the infrared thermal imaging, the inspection robot, the sound acquisition instrument and other devices are adopted to replace manual inspection, so that the inspection efficiency is effectively improved, and the working intensity of personnel is reduced.
Description
technical field [0001] The invention relates to the technical field of inspection, in particular to an intelligent inspection method for equipment of a large hydropower station. Background technique [0002] Large-scale hydropower station equipment inspection management is an important work content of power station personnel. At present, the inspection method of hydropower station equipment relies on inspectors to inspect the equipment on site, and relies on personnel to judge and record whether the equipment is running normally. This traditional method has problems such as untimely inspections, personal safety risks, large manpower requirements, and inability to scientifically analyze and predict equipment performance data. It cannot detect and eliminate hidden dangers in time and affect the safe and stable operation of equipment. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of manual inspection of hydropower sta...
