The system of claim 4, wherein the comparison of the emergency efficiency coefficient to the emergency efficiency coefficient threshold comprises: if the emergency efficiency coefficient is smaller than the emergency efficiency coefficient threshold value, judging that the emergency treatment of the workshop i is qualified, and marking the corresponding workshop as an emergency qualified workshop; and if the emergency efficiency is larger than or equal to the emergency efficiency coefficient threshold value, judging that the emergency treatment of the workshop i is unqualified, and marking the corresponding workshop as an unqualified emergency workshop.
6. The system of claim 5, wherein the process of obtaining the emergency qualification coefficient comprises: acquiring the number of emergency unqualified workshops and marking the number as o, marking the ratio of o to n as emergency qualification rate, acquiring an emergency qualification rate threshold value through a storage module, comparing the emergency qualification rate with the emergency qualification rate threshold value, and judging that the emergency treatment of the industrial control system is unqualified if the emergency qualification rate is less than or equal to the emergency qualification rate threshold value; if the emergency qualified rate YH is larger than the emergency qualified rate threshold, judging that the emergency treatment of the industrial control system is qualified; and sending the emergency qualified rate YH of the industrial control system to a safety rating module.
