Numerical control system access control system based on access control agent and working process thereof

The invention provides a numerical control system access control system based on an access control agent, which comprises a subject, an object and an access control agent, and is characterized in that the subject is an entity capable of actively accessing and initiates an access request to the access control agent; the access control agent judges whether the access request is legal or not and returns a request result to the main body; the object accepts access initiated by a legitimate subject via an access control agent. According to the access control agent designed by the invention, both the object and the subject of the numerical control system are registered on the access control agent, and the subject performs access control check through the access control agent before accessing the object, so that the unification of the access control system of the numerical control system is realized; and extra development is not needed. 本发明提供一种基于访问控制代理的数控系统访问控制系统，包括主体、客体和访问控制代理，其中，所述主体为能主动进行访问的实体，向访问控制代理发起访问请求；所述访问控
