Description
Technical Field
The invention belongs to the field of campus safety management methods, and particularly relates to a campus school safety double prevention system based on a dynamic model.
Background
In 2019, a Henan province education hall formulates an implementation scheme for promoting a safety risk hidden dual prevention system in 2019 of a Henan province education system, and the construction of the safety dual prevention system in the education system is developed for the first time. The current safety situation of the campus of colleges and universities can be summarized as follows: "invisible, unexpected and no longer alive". In order to solve the problems, a campus safety dual prevention system is provided, and the core idea is to focus on prevention: firstly, safety risk identification and management and control; secondly, hidden danger troubleshooting is carried out. Two firewall are arranged, and hidden danger is prevented from being in a bud state.
At present, the construction of a campus safety dual prevention system is still in a starting stage, and no mature and complete method can be borrowed. Some colleges, provincial level exemplary focus highs are making exploratory attempts. After investigation of the construction conditions of the units, the defects of the existing method are found in that:
(1) simplification and staticizing of risk level identification
The four colors representing the risk levels are adopted to identify buildings, places, areas or facilities and the like, so that people can rapidly judge the risk levels through the risk colors, keep away from risks and avoid injuries.
The influence of time factors on the risk level is not considered in the existing method. For example, projectors in a classroom are less likely to be stolen during class and night study hours. But after 10 o' clock at night, the risk of the projector being stolen is greatly increased.
The existing method does not consider the influence of event factors on the risk level. For example, if a classroom is occupied, developing lectures, reports, etc. that are unrelated to normal teaching, academic, campus recruiting, student activities, etc., may increase political safety risks.
(2) The factor without considering human is the biggest root cause of hidden trouble
In the campus security relationship of 'human-facility-environment', facilities and environment are stable factors and are easy to manage, and only human is the most active factor and is difficult to master and manage. Human factors mainly include the following aspects: first, population density; secondly, psychological and physiological factors of human beings; third is a manager factor; and fourthly, illegal outside school personnel. College campuses are areas with high crowds, and the risk level is increased due to the increase of the number of people. The risks that may arise from the gathering of people include: the event is stepped on by people, the casualty event caused by natural damage, the casualty event caused by potential safety hazard, the social security event and the public health event. Human bad mind: disturbance of emotional levels, influence of adverse attitudes, influence of adverse motivations, deterioration of human behavior, distraction; physiological factors of human: the occurrence of illness or injury, fatigue, drinking and the like can cause unsafe behaviors, the behaviors are not easy to directly perceive but really exist, and serious personal injury can occur due to poor management and control. The manager factor is mainly the responsibility. No matter how perfect and efficient the "campus security dual system" is, if people without responsibility center are allowed to manage, control, all the security systems, facilities, and systems will be similar to the nominal ones. Illegal persons are mixed in the campus to carry out activities such as theft, personal injury, fraud, unsafe traffic behavior and the like, and the safety and stability of the campus are seriously influenced.
(3) Staticizing and formalizing hidden danger troubleshooting process
The existing hidden danger checking and processing method comprises the following steps: and establishing a paper work account, periodically checking hidden troubles by a responsible person, finding and processing hidden troubles, and filling a paper record account. The defects of the prior art are as follows: firstly, the paper ledger is not convenient for discovering, reporting, processing, feeding back and monitoring potential safety hazards in real time, and is a low-efficiency operation mode; and secondly, the workload of the manager is not reduced, but the working program is more complex, and the manager spends a great deal of energy on filling the safety account.
(4) The influence of the hidden danger processing process and result on the risk level cannot be reflected
The prior art does not establish a link between the hidden danger handling process and the risk level change, and the hidden danger handling process and the risk level change are disjointed. The risk is changed from low to high once hidden danger occurs; the hidden danger is handled in time, the risk is reduced from high to low, and the dynamic process needs to inform and remind people in the hidden danger area. However, the disadvantages of the prior art cause the hidden trouble to be treated and not treated, the displayed safety level is the same, people are not aware that the hidden trouble is in danger, and the injury caused by the situation can be huge.
(5) The matrix mathematical model adopted by the risk evaluation is too simple and can not be matched with the real situation
Mathematical model of risk of matrix method: r ═ L × S where: r-risk degree, risk; l-likelihood, the likelihood of outcome occurrence; s-severity, the severity of the possible consequences. The model does not consider four factors of personnel, time, events and risk investigation processing procedures, is a staticized mathematical model and is not suitable for the construction of a complex safety prevention system of a campus.
