Abstract:Following the deepening reform of the power system in China, the construction scale of the transmission lines continues to expand. The rapid development of the economy, the continuous progress of the society and the gradual improvement of the people''s living standards have put forward higher requirements for the safety of the power system operation. In order to keep up with the current form, the power needs of the whole society are constantly improved. For the power supply enterprise must strengthen the quality control of transmission line safety. State Grid Longyan power company to "168" development strategy system as the core of a new era, based on the "Internet plus" and "big data" technology oriented development, in order to improve the shortcomings of the traditional inspection mode, in order to promote the transmission of interactive inspection safety and quality control for the lead, to construct the "process control" for the purpose of transmission interactive tour Check the management and control mode, build the information exchange platform of "integrated engineering", form a "whole record" inspection database system, and improve the safety quality and efficiency of inspection work in all directions. After the application of the control system, it can ensure the integrity of inspection data, reduce the leakage rate of the defects, shorten the response time of the emergency events, the time of the new training and the statistics time of the common reports and so on, so as to improve the safety quality of the inspection.
