Abstract：Disaster monitoring system is an important guarantee for high-speed railway safety. With the rapid development of highspeed rail，the field maintenance of disaster monitoring system is put forward higher request. The research and optimization of PCC main standby redundancy mechanism and handover strategy is carried out to reduce the probability of disaster monitoring sites from monitoring and improve the quality of disaster monitoring system effectively.
Keywords：disaster monitoring system；PCC；redundancy
