if so, determining a third person position of the second non-abnormal person from the distribution of the evacuated persons, determining a turn-back distance of the second non-abnormal person based on the third person position, the second person position and the safe evacuation route, and taking the second non-abnormal person corresponding to the minimum turn-back distance as a target person suitable for helping the abnormal person.
10. An on-site emergency evacuation method based on radiation monitoring is characterized by comprising the following steps:
step S1: when radiation danger is early warned in a nuclear power station area, monitoring the radiation condition in the nuclear power station area in real time;
step S2: acquiring a first person position in a nuclear power station area;
and step S3: planning a safe evacuation route based on the radiation condition, the first person position and a preset internal map corresponding to the nuclear power station area;
and step S4: and carrying out emergency evacuation on personnel in the nuclear power station area based on the safe evacuation route.
