GUARDING SYSTEM AGAINST ATTACK FROM MENTALLY DISTURBED PATIENTS
TECHNICAL FIELD The present disclosure relates to the technical field of information, and in particular to a guarding system against attack from mentally disturbed patients.
BACKGROUND ART The risk assessment standard published in the Code for the Management and Treatment of Severe Mental Disorders (2018 release) is simple, which only considers behavior and ignores multi-factor risks. It is seriously separated from pathological mental symptoms. It can only be used as a simple classification to facilitate follow-up management, and it is impossible to accurately assess whether the disease occurs and whether the disease is serious. Most grass-roots management and control people have limited manpower and have multiple jobs, and rely on telephone follow-up so as not to play an effective role in supervision.

In order to obtain a feature quantity that can reflect the patient state more completely, it is necessary to further process the grey correlation r.
Assuming that W = [wi we ws] is the weight matrix, where Wi W2 W3 correspond to the low, medium and high weight coefficient of patients, indicating the proportion of low-, medium- and high-level components in mental diseases of patients, respectively, wherein the coefficients are generally judged by experts, and wi wy ws satisfies wi + we + wa = 1. According to step2, the characteristic matrix Rgparient = [ro1 Fez Fos] of the patient can be known, wherein ro Fos ros correspond to the three correlation coefficients Tm, ro: and rg: obtained in step2, respectively.
The calculating formula of the state coefficient R is as follows: Ww, R= R ien ey = [7 Bor Tos ] OW, | SW Fy TW) Fy TWF, wy X'iow represents transposition of matrix Xiow, X'medium represents transposition of matrix Xmediums X'nigh represents transposition of matrix Xig5, and W' represents transposition of matrix W.
The final coefficient R is the severity score in different levels, and Ris a value between 0 and 1. When R is larger, it means that the patient is more serious in the current level.
Furthermore, when the patient level is low, R=w ry when the patient level is medium, R=W hy WK, when the patient level is high, R=w hj Wi +W, I,
According to the present disclosure, three weight coefficients are preset and three correlation coefficients ra, ro; and re; are calculated to realize more accurate numerical quantification of mental state of mentally disturbed patients.
The present disclosure has the beneficial effects that by monitoring physiological information, activity videos and voices of patients, symptom and risk state evaluation data are automatically acquired and sent to the server for graded early warning.
When the mentally disturbed patient is in an unstable state of a set danger level, the risk state coefficient is large and is close to a high-risk group, the computer sends an alarm to an administrator of the high-risk group in time, the administrator takes emergency measures quickly, and the danger that the high-risk group is attacked by the mentally disturbed patient can be reduced.
