First, why the use of power line inspection system? ?? Power transmission and distribution lines is very important, overhead transmission and distribution lines are widely distributed in nature run long-term exposure, not only to withstand the effects of normal mechanical loads and loads of power, but also by various external factors interfere with nature the ever-changing impact. These factors will be spurred on line component aging, fatigue, oxidation and corrosion, if not timely detection and slashing, from quantitative to qualitative change will develop into a variety of failures. Nature of atmospheric contamination, lightning, high winds, flooding, erosion, landslides subsidence, earthquakes, bird damage and external forces, such as transmission and distribution lines for damage, if not early and take preventive measures, will result in a variety of line fault. ?? Second, the traditional inspection methods, there are many hidden dangers ?? one can not objectively true master in place and check the conditions of inspection personnel inspection, missed serious condition. Old patrol inspection system is difficult to ensure the quality of the staff unable to examine whether each of the towers, each device, each item to be checked?, Records are not standardized, due to complex inspection program content and their knowledge of inspection personnel different levels of accumulated experience, so fill in the content, or simple or complex, or captivated focus, or grasp the essence of the tedious and time-consuming, each question item, should be recorded by the pen to the paper, if necessary, supplemented by mapping needs , 10kv or more lines, each project requires poles of recording, the amount and time-consuming. ?? 2, post-processing is difficult: a large number of data for each inspection of the collection, processing, analysis, workload, due to the large amount of data, loss seriously. ?? 3, assessment is difficult: it is difficult for staff to work qualitatively and quantitatively evaluated. ?? 4, the reference value of the single: Health grid and ancillary facilities, parameters such as historical data can not effectively use the query inconvenience defect analysis equipment, equipment selection, unable to implement decision support. ? Third, the Chilean hit a power line inspection program ??, standardized and unified, standard operating instructions, including each item of equipment (overhead transmission lines, switching devices, towers, transformers, wires, transformers, power distribution cabinets, etc.) Check the contents, check the method, the normal reference standards, focus on examination of the project. 2, and personnel, given time, a given task, given the standard-setting cycle inspection program; 3, when patrol entered manually or select equipment operating status, parameters, changes in the surrounding environment, discover hidden defects and the use of images, video, text, scene evidence , so that managers first time to understand the situation, for these visual information can be immediately assigned to accurately determine whether you need repairs, or the inclusion of post-maintenance plan. 4, the work of inspection personnel quantitative assessment, all from an automated system statistics, analysis, generate a variety of assessment reports. Can visually see the completion of the inspection points, missing patrol point location on a map. And automatically record the track inspection, work location in real-time supervision and inspection personnel checks, inspection of historical trajectory dynamic playback, convenient access to the manager at any time to verify. 5, transmission lines are exposed to in the wild, especially a wide range of transportation is not convenient, when the sudden failure of critical equipment, can be a key to send alarm linkage platform will receive alert notifications and SMS notifications directly to the relevant person in charge. On the map marked the alarm personnel ready position, the surrounding environment, from the point of failure nearest repair personnel, immediately issued a repair mission, the direct maintenance, reducing recording, reporting, assignment, on-site maintenance and other intermediate links, improve emergency rescue work, so fault accidents to a minimum. 6, handheld terminal Chinese display, Chinese voice broadcast, track record, point assessment, data transmission all done automatically by the system, without human intervention, simplifying inspection personnel workload for quick submission of data for a variety of different work cultures degree personnel.
