Description
Technical field
This utility model relates to a kind of experiment building based on Internet of Things and meets an urgent need safety-protection system.
Background technology
China in Recent Years colleges and universities are because the resource optimization restructuring trend in multi-campus school-running, and many school districts are not even in same city.Again because colleges and universities add the function of cultural exchanges and science service in recent years, open to the society, have shared teaching resource, therefore in colleges and universities, structure of personnel is complicated, become severe campus security problem, the traditional mode unifying security protection from campus is changed into scattered each laboratory building alone for the state of political affairs so that the operating pressure of Security Department of colleges and universities is doubled and redoubled, and occurs in that the phenomenon that colleges and universities security protection human resources is not enough.
In this context, colleges and universities gradually simplify the defendance secretary in charge of something of sole duty, and security protection work is relied on societal forces, and this creates again new potential safety hazard.The mobility of people that security company sends is big, is unfamiliar with laboratory, cannot be promoted again the Specialized Quality of security personnel by short-term cultivation.Some special experimental laboratories have an accident when, security personnel is without deep specialty background, and the emergency measure that may take is improper, causes causality loss to expand, and even jeopardizes the life security of security personnel.
The alarm that graduation design uses at present mainly has the most several: acousto-optic type alarm, radio type alarm, closed-circuit control class alarm, internet class alarm, mobile network class alarm.Acousto-optic type alarm is because floor completely cuts off, and chimes of doom is significantly weakened, and in experiment building, using effect is bad.The alarm of radio type is because signal transmitting range is limited, and when multiple alarms work simultaneously, signal easily interferes, and reliability increases along with communication distance and declines rapidly.Widely apply in colleges and universities at present is cctv surveillance, reliability is higher, but coaxial cable wiring installation cost is high, information delivery areas is closed, accident warning message can only be sent to night shift room of ensuring public security, cannot directly inform the person liable of laboratory, cause accident disposal efficiency to decline；The alarm of internet class has many advantages, but use in colleges and universities' experiment building and receive many restrictions, colleges and universities' experiment building can only be connected into campus network with campus network dialers such as the StarNet, and the alarm of almost all of internet class cannot cannot use by built-in campus network dialer；Mobile network's class alarm is the most flexible, can be connected into the Internet by the wireless mode such as GPRS or 3G, 4G, WIFI, it is possible to realize telecommunication, is therefore best suited for graduation design and uses.
Modern university type of laboratory becomes increasingly complex, and as a example by fire, the emergency disposal flow process of chemical laboratory, pathogenic bacteria laboratory, Dynamic Test Chamber and precision instrument experiment is entirely different, and the fire retardant mechanism of employing is different, and the fire suppression measures of use is the most different.On August 12nd, 2015 Binhai New Area in Tianjin dangerous goods store breaking out of fire, first rushes towards the fireman in front in the case of information is not clear, hasty between select tradition water to go out mode suppress the intensity of a fire.A large amount of water, it may be possible to cause carbide and the main cause of metallic sodium huge explosion." 8.12 accident " causes 104 firemans to sacrifice altogether.This event is a warning to the management work of Scientific Research in University Laboratory, and security personnel is in confused situation to the laboratory internal of burst accident, it is also possible to the conventional water mode of going out is applied to the fire of special experimental laboratory, thus causes bigger accident.
In order to assist to ensure public security treatment of laboratory accident more steadily, when special experimental laboratory has an accident, except allowing laboratory expert get involved as early as possible, each laboratory also should set teachers and students security official.Laboratory expert and teachers and students security official are familiar with the layout of laboratory, grasp Professional knowledge, can overcome the disadvantages that the defect that programme of ensuring public security knowledge is not enough, can reduce causality loss.But accident often incident is suddenly, how high efficiency scheduling is dispersed in laboratory expert everywhere and teachers and students security official, becomes a difficult point of safety-protection system.
Gate inhibition is the important component part of colleges and universities' experiment building security protection.Pass through market survey, existing gate control system such as hotel gate control system uses MifareoneICS50 card in a large number, only by the identity of series number identification passenger, and the series number of MifareoneICS50 card is by hack, use Hacker Program and the S50 card of special rewritable series number, get final product cloning access card, define safety issue；Some gate control system lacks the centralized management of " networking ", and each door of this kind of system is independently arranged, and lacks combined network communication function, it is impossible to realize centralization, visualized management；Major part gate inhibition lacks the Design Thinking of " the Internet+", only includes LAN centralized management system in, when security personnel leave server patrol, just cannot understand the safe condition of periphery gate inhibition in real time.
