The invention provides a GIS-based 
power transmission line intelligent patrol inspection 
system, which a comprises 
server and a mobile terminal, wherein an 
electronic map is set up in the 
server, and the 
server and the mobile terminal performs exchange and sharing with each other through a network; a user authority management module, a pole 
tower data management module and a status patrol inspection management module; and an electronic sign-in module, a map editing module, a positioning module, a line patrol trajectory recording module, an off-line data module, an instant communication module, a data interaction module and a query statistics module are installed in the mobile terminal. The GIS-based 
power transmission line patrol intelligent inspection 
system integrates the 
computer technology, the GIS technology and the 3G 
wireless communication technology, inputs 
power transmission line basic data, personnel attendance information, line defect information and the like into the 
system in standard forms, reduces the 
workload of patrol intelligent staff, and effectively solves the problems of low personnel attendance rate and poor real-time performance in patrol inspection; and the GIS-based power 
transmission line patrol intelligent inspection system can learn about the operating conditions of a power 
transmission line comprehensively, and discover and solve the problems of defects and hidden dangers in the power 
transmission line timely.
