Railway power supply system network safety monitoring system

The invention relates to a railway power supply system network safety monitoring system. The system comprises a host monitoring module which monitors a safety event of substation host equipment through sensing the safety event of the substation host equipment, and uploads the sensing information to a background server; a network equipment monitoring module is used for monitoring safety events of the network equipment by sensing the safety events of the network equipment and uploading sensing information to the background server; a safety and protection equipment monitoring module is used for monitoring safety events of the safety and protection equipment by sensing the safety events of the safety and protection equipment and uploading sensing information to the background server. The system can more stably and comprehensively monitor important network safety equipment of each substation of the railway on line in real time, identify the abnormality of the system equipment in advance, improve the network safety
