Transmission line inspection management is to ensure the safe and reliable operation of the power grid of a basic work. Through the line inspection workers could find that the potential risk factors, the necessary maintenance. So as to ensure the safe and reliable operation of the entire power system, this article designed an intelligent inspection system. The inspection system integrates the global positioning system, geographic information system, computer network communication technology. It can minimize the leakage detection system, the wrong test, saving costs, increase business efficiency and ensure safe and stable operation of transmission lines. In addition, the system can effectively supervise and manage the inspectors to ensure that the inspection is in place record, store and position reminders of incident data such as faults, accidents and equipment defects during the inspection process, and command personnel. But it makes it easier to pay close attention to the operating staff, so that it can grasp the safety of field staff in a timely manner, when an emergency situation can quickly locate the staff, and according to the system to provide navigation guidance to give the appropriate support or organization to rescue, And effectively put the “people-oriented, safety first” concept to implement.
