Research on Handheld Mobile Inspection Terminal Based on Beidou Communication

Sichuan power grid has a large number of transmission lines in the complex terrain, which’s communication is blocked. Inspection of transmission lines is often difficult and risky. Because the beidou satellite communication system is not affected by geographical environment and limit of communication network station, handheld mobile inspection terminal based on beidou communication implements real-time two-way short message communication, automatic navigation and positioning, SOS distress, and other functions in no man area. The terminal is helpful for the real-time intelligent recording circuit status in the transmission line patrol, guaranteeing the personal safety of the inspection personnel and improving the efficiency of the grid management system, which is of great application value.
