Abstract: Based on satellite positioning, electronic sensing, radio frequency identification and infrared camera technology,this paper designed a safety monitoring module for the field operation of permanent way of high-speed railway. Intelligentterminal was used to integrate various hardware technologies and exchanged information with B/S system platform toimplement the whole process monitoring for the field operation of permanent way of high-speed railway. The system has beenapplied in many stations. Through collecting and analyzing the data related to the field operation, it could be seen that thenon-standard situation of the field operation gradually decreases, which met the personal safety requirements of the operatorsand implemented the reliable protection of the driving safety. The application results show that the monitoring method canreduce the unsafe factors to the field workers, and provide useful exploration and practice for the intelligent operation andmaintenance of the field operation of permanent way.
