RESEARCH ON DESIGN OF SAFETY NETWORK IN SEWAGE TREATMENT CONTROL SYSTEM OF HOSPITAL

摘要

This study takes the sewage treatment control system as the research object. On the basis of studying the sewage treatment process, the safety network in the control system of hospital is studied. An improved non-parametric CUSUM network security intrusion detection algorithm is proposed, which effectively solves the traditional problem that the probability distribution in the CUSUM algorithm is difficult to obtain and the probability density is difficult to calculate. The results show that the network security mechanism has better defense capability and achievability, which improves the network security in the sewage treatment system.
