Keywords:: Smart fire protection construction of university archives0 IntroductionUniversity archives are important custodians of the historical memory of colleges and universities, and fire safety has always been the high-voltage line for the safety of university archives. In 2017, the Fire Bureau of the Ministry of Public Security issued the "Guiding Opinions on Promoting the Construction of "Smart Fire Protection", proposing guidance on the construction of a "Smart Fire Protection" system. [1] Under the new situation, university archives should use the "smart fire protection" system to build a strong fire safety defense line for university archives and ensure the inheritance and continuation of the historical memory of colleges and universities. 1. Functions and advantages of intelligent fire protection system1.1. The development and popularization of a new generation of information technology such as 5G and artificial intelligence of intelligent fire protection system, people's lives have undergone earth-shaking changes. As a new thing, the intelligent fire protection system is based on the premise of public fire safety needs, with the support of the Internet of Things, cloud computing, big data and other technologies, based on various fire protection data, combined with electronic maps, communication technology, information technology and mobile positioning, intelligent collection of fire protection systems, fire fighting equipment, fire emergency plans and fire protection facilities and other relevant information, and analysis, processing and auxiliary decision-making, etc., can break the fire safety information island, maximize the elimination of potential safety hazards, and realize intelligent fire extinguishing. Ensure the safety of the prevention and control area. 1.2. Functions of smart fire protection system 12.1. Hidden danger early warning and monitoring functionThe intelligent fire protection system can collect and analyze fire safety-related data in the prevention and control area, study and judge fire hazards, and reduce the blind spots of fire hazard monitoring, including intelligent electricity monitoring system and fire equipment operation monitoring. The intelligent electricity monitoring system is responsible for monitoring the electricity load in the prevention and control area, and if the electricity in the prevention and control area is overloaded, the system will issue an early warning of hidden dangers and eliminate potential fire safety hazards in time. The operation monitoring of fire-fighting equipment is responsible for real-time monitoring of fire-fighting equipment such as smoke temperature detectors, fire extinguisher sprinklers, and fire extinguishing cylinder pressure in the prevention and control area, so as to realize the failure alarm of fire-fighting equipment and ensure the normal operation of fire-fighting equipment. 1.2.2. Hidden danger early warning and monitoring function: In addition to the common smoke temperature sensing fire detection, the intelligent fire protection system is also equipped with an image-type smoke detector. The image-based smoke detector is a two-in-one product of smoke and temperature, based on the deep learning algorithm of Nien Optoelectronics Technology, its camera can realize unattended uninterrupted work, automatically find the fire signs in the monitoring area, alarm in a fast and suitable way, and reduce the phenomenon of fire understatement. In reality, different systems and different brands in a prevention and control area form fire safety information islands. With the help of a unified management software platform and electronic map function, the intelligent fire protection system is compatible with the functions of various subsystems and various fire alarm brands, and the system will immediately start the sound and light alarm when the fire is detected at any location, and the fire alarm information will be sent to the platform and the total elimination control room through mobile Internet technology, and automatically dialed for fire alarm. 1.2.3. When the fire situation occurs in the linkage fire extinguishing function, the intelligent fire protection system proposes a fire extinguishing plan on the basis of data collection and analysis. Through the electronic map positioning, the fire extinguishing system controller, fire shutter, smoke exhaust fan, etc. are issued to start the instruction to automatically extinguish the fire. The intelligent fire protection system can also monitor the fire situation in real time through image-based smoke detectors and apps, and adopt man-machine collaboration to remotely control the eruption position and dose of fire extinguishers, so as to improve fire extinguishing efficiency. 1.3. Advantages of the smart fire protection systemThe smart fire protection system uses cloud computing, Internet of Things and other technologies, follows the principle of "information exchange, fast and convenient", and uses unified data standards and standardized data sources to collect, sort, count and analyze data and information inside and outside the prevention and control area, provide data and information support for fire protection work, and realize fire hazard monitoring, fire early warning, and linkage fire extinguishing intelligence. The advantages of a smart fire protection system. First of all, the intelligent fire protection system realizes 24-hour grid monitoring and management of the prevention and control area from points, lines and planes, effectively eliminating the blind spots in time and space of fire safety work. Secondly, due to the intelligent characteristics of the intelligent fire protection system, it can check hidden dangers in time, issue early warnings, and start the fire extinguishing system to carry out intelligent fire extinguishing, shorten the fire extinguishing time, and greatly improve the fire extinguishing efficiency. 2. The dilemma of fire safety work in university archivesIn just two months from September to October 2020, there were four college campus fires across the country. With the continuous development and growth of the scale of colleges and universities, university archives are facing more and more fire safety hazards. 2.1. The number of collection resources is large, and there are many flammable carriers, and the second article of the "Measures for the Management of Archives of Colleges and Universities" stipulates that the archives of colleges and universities are historical records in the form of various carriers, such as texts, charts, audio-visuals, etc., which are directly formed by institutions of higher learning engaged in teaching, scientific research, party and government management and other activities, and have preservation value for the school and society. University archives cover all aspects of the development of colleges and universities, and are the carriers of historical memory of colleges and universities. University archives are the centralized storage places for university archives, and in addition to a large number of paper archives, the collection also includes flammable carriers such as film, CD, and disk; Most of the office furniture in the reading room, the whole file room and the office of the university archives is flammable wooden furniture. In short, there are many flammable materials in the university archives, and there are great fire safety hazards. 2.2. There are many electrical equipment in the library, the line operation is overloaded, and the archives are highly professional and technical, and the university archives are the archives workplace, and there are special requirements for the road control. Most university archives are converted from offices, classrooms or other places, and the lines are not modified accordingly during the renovation process. Due to the special preservation requirements of the archives, there are a large number of air conditioners, constant temperature and humidity systems, disinfection equipment, binding equipment, computers, printers and other electrical equipment in the archives, including many high-power electrical appliances, some of which are running 24 hours a day. There are many electrical equipment, high power and long running time, which virtually increases the load of the line, which is easy to cause short circuit and cause electrical fire. 2.3. The fire-fighting facilities are not fully equipped, and the fault maintenance is not timely, although it has been emphasized that the archives are the units of college fire protection, but due to insufficient understanding and lack of capital investment, the university archives generally have the problem that the fire-fighting equipment is not complete, the maintenance is not timely, and the fire-fighting equipment is virtually useless. The Code for the Design of Archives Buildings stipulates that archives warehouses should be equipped with clean gas fire extinguishing systems or high-pressure water mist fire extinguishing systems. However, some university archives still use water sprinklers or ultra-fine dry powder fire extinguishers in their warehouses, which not only do not meet the requirements of the fire extinguishing equipment, but also the number of fire extinguishing equipment equipped is not up to standard. In addition, problems such as the failure of regular inspection of fire-fighting equipment, the failure or false alarm of smoke temperature sensing system, the failure of fire extinguishers to refill in time, and the failure of alarm system and fire extinguishing system to link are widespread. 2.4. The daily supervision is not effective, the fire emergency response is lagging behind, and "prevention first, prevention and elimination combined" is the guiding principle of fire safety work in college archives. Constrained by ideological understanding, there are certain loopholes in the fire safety work of some university archives. For example, the fire safety responsibility system has not been established, the fire safety inspection and supervision is not effective, and the 24-hour duty system is not in place. Some university archives are located in remote locations, and if the daily supervision and inspection are not in place, there is no way to respond in time when a fire occurs, and the fire emergency response lags behind. 2.5. Weak safety awareness and lack of fire protection knowledge, university archives are the service window to provide archives use, and the flow of personnel in the museum is large. Some visitors have a weak awareness of fire safety, violate the non-smoking regulations of the archives, smoke in the toilets or public areas of the archives, and even litter cigarette butts. University archives staff have little knowledge of fire safety; Some university archives rarely carry out fire safety knowledge training and fire safety drills in the library; Some university archives staff don't even know how to use fire extinguishers, hydrants and other commonly used firefighting equipment. 3. Under the new situation, it is of great significance for university archives to build a smart fire protection system3.1. The inevitable requirement of the construction of "smart campus" has always been that colleges and universities are the country's highlands of science and technology. In the 80s of the 20th century, the construction and popularization of digital campuses made the important fields of university teaching, scientific research, and archives basically realize informatization. In the context of the rapid development of the social smart ecology, the digital construction of colleges and universities has entered a new milestone, and the "smart campus" was born in response to the needs of the development of the times. "Smart campus" is the promotion and expansion of the digital campus, and the form of campus digital construction; It comprehensively uses new information technology to perceive the physical environment of the campus, intelligently identify various business scenarios of the school, and organically connect the physical space and digital space of the school, forming an interactive and personalized intelligent innovation management model. The construction of "smart archives" and "smart fire protection" are both important parts of the "smart campus", and they play an important role in the construction of the "smart campus". The construction of smart fire protection system in university archives is not only an inevitable requirement for the construction of "smart archives" in colleges and universities, but also an inevitable requirement for the "smart fire protection" project in the construction of "smart campus" in colleges and universities. Therefore, under the new situation, the construction of intelligent fire protection system in university archives is of great significance. 3.2. An effective way to improve the fire safety governance ability of university archivesStarting from the actual work of university archives, the smart fire protection system of university archives includes the management function of smart fire protection resources of university archives, the environmental monitoring and real-time data collection function of the warehouse and other areas of the museum, the data collection function of the Internet of Things for the operation of fire protection facilities in the museum, the evacuation execution management function of the emergency channel in the museum, the safety big data analysis function of the archives, the fire warning function and the intelligent fire extinguishing function of the archives. In order to improve the modernization of the archives governance system and governance capabilities, the fire safety work of archives in colleges and universities should also keep pace with the times. The construction of the intelligent fire protection system effectively solves the problems and hidden dangers in the current fire safety work of university archives, realizes the transformation and upgrading of the fire prevention work mode of university archives from "remedial" to "early warning", effectively shortens the response time of fire emergencies, reduces the probability of major fires, improves the fire safety management ability of university archives under the new situation, and helps the construction of "safe campus". 4. Suggestions on the construction of intelligent fire protection system in university archives under the new situation4.1. Leaders attach importance to and clarify the division of responsibilities and responsibilities The fire safety work of university archives is not only the top priority of university archives work, but also the campus safety work of colleges and universities. Any mistake in the fire safety work of university archives will bring immeasurable losses to the development of college education. Leaders of colleges and universities should attach great importance to the construction of smart fire protection systems, determine a school leader to be in charge of the construction of smart fire protection systems in archives, and incorporate the construction of smart fire protection systems in archives into the overall planning of the construction of smart fire protection systems on campus, so as to ensure that the construction of smart fire protection systems in university archives is planned and deployed. In addition, since the construction of smart fire protection in university archives is a complex system project, colleges and universities can set up a leading group for the construction of smart fire protection system in archives, including archives, security office, logistics management office, infrastructure office, assets office, finance office, network information and other departments. The leading group has a special work office, which is responsible for coordinating and handling the daily affairs in the construction of the smart fire protection system of the archives. In the process of establishing the leading group, it is necessary to clarify the division of responsibilities of the relevant functional departments in the construction of smart fire protection in university archives, prevent prevarication, and ensure that all functional departments perform their duties in the process of building the smart fire protection system of university archives and jointly promote the smooth progress of the project. 4.2. Funding guarantee, complete equipment and facilities, university archives smart fire protection system project in addition to the purchase of smoke temperature detectors, alarm hosts, fire extinguishing equipment, fire extinguishing equipment host controllers and other fire-fighting equipment, but also need computers, optical fibers, cloud memory and other instruments and equipment. In addition, the construction of smart fire protection system also involves the infrastructure transformation of buildings, line replacement, etc. After the construction of the project is completed, it is necessary to regularly carry out post-inspection, maintenance and replacement of equipment. It can be seen that the construction of the intelligent fire protection system of the university archives is a project with a long construction period and large capital investment. Colleges and universities should set up special funds for construction to provide financial guarantee for the construction of smart fire protection systems in archives. Equipped with all kinds of equipment and facilities required for the smart fire protection system, and reserve space for expansion to prepare for the transformation and upgrading of future projects. 4.3. Improve the system and strengthen the construction of the supervision and intelligent fire protection system, the purpose of which is to prevent fires. After the completion of the construction of the hardware facilities of the smart fire protection system, it is still necessary to improve the fire safety rules and regulations and strengthen the daily inspection and supervision. Specifically, it includes improving the fire safety responsibility system of the archives, the fire emergency plan of the archives, the daily inspection and registration system of the smart fire protection equipment of the archives, improving the daily management ledger of the smart fire protection system of the archives, regularly inspecting the management ledger, implementing the 24-hour duty system of the general elimination control room, and regularly or irregularly checking the duty of the elimination control room. By improving various systems and strengthening supervision, we can ensure that fire hazards can be discovered and reported in a timely manner, and improve the emergency response capability of archives to fire emergencies. 4.4. Strengthen training and improve the quality of personnel, and university archives should invite fire departments or fire prevention professionals, and smart fire equipment to proofread and proofread regular or irregular fire protection knowledge and system operation training for archives staff to improve the quality of personnel. The archives can also remind the teachers, students and staff of the museum by posting fire safety slogans such as "fire-fighting equipment, non-emergency is strictly forbidden to touch", so as to prevent the fire-fighting equipment from being falsely alarmed or activated due to curiosity and avoid unnecessary losses. 5.
