As the main artery of national economy, railway, electricity, gas and energy play a decisive role in economic development. For the equipment applied in these fields, great importance should be attached to their safety and maintenance, which concern the safety of the state and people's lives and property. With the deepening of reform and opening up as well as the development of national economy, public security incidents and hidden dangers are increasing in the fields of railway, electricity, gas and energy, which results from the complexity of rails and tracks, turnouts, signal lamps, systems, facilities and other basic conditions regarding railways, power systems and energy systems, so it is a necessity to check equipment and apparatus, instruments and vehicle conditions on a regular basis and inspect the devices and communication lines applied along the facilities. Therefore, the adoption of an internationally advanced intelligent patrol inspection management system is undoubtedly a powerful measure to eliminate various hidden safety hazards.

Relying on its R&D strength in BDS positioning technologies, Wuhan Mengxin Technology integrates BDS/GPS high-precision positioning systems, mobile communication system, comprehensive energy consumption management system and other systems effectively, and offers BDS high-precision personnel positioning and patrol inspection terminal based on location service. The real-time positioning is accurate to less than a meter. In combination with the intelligent management platform for BDS positioning, the terminal coordinates such functions as personnel management, systematic scheduling, supervision of patrol inspection, and analysis and reporting of problems conveniently and effectively. The comprehensive patrol inspection capabilities in the fields of railway, electricity and energy are improved by informationized and scientific means.
