Non-centralized area access safety protection method and system

The invention is suitable for the technical field of railway non-centralized area intelligent safety control, and provides a non-centralized area access safety protection method and system. The methodcomprises the steps that an SAS system starts/silences a shunting route safety protection function when a shunting vehicle enters/leaves a non-centralized area; the SAS system automatically makes a locomotive stop when a shunting operation plan is inconsistent with an access opening station track, field equipment is abnormal, stop locomotive invasion (standard pressing) is generated and a shunting locomotive signaling is received; an SAS system shunting operation plan automatically reports points; and the system performs visual intelligent management. Therefore, visual real-time control of dispatching and commanding on the state of the field equipment can be realized, field personnel are guided to work, safety protection under abnormal conditions is realized, the occurrence of operation risks is prevented, and tr
