Campus Security System Based On Single Chip

With the development of today’s society, the campus security problemsbecome more attention. By establishing all-round three-dimensional campussecurity system to minimize risk, campus security system will be to protectstudents’ safety at the same time, it`s important to control all kind ofsituation. On the type selection of equipment, need to consider the price isrelatively cheap, relatively complete Microcontrollers to implementperformance.In the process of design, the reference study of community andcampus security systems at home and abroad, combined with the actual situationof hulun buir college this system are designed. This system mainly has thefunction of is Video acquisition、Daily display、Fire alarm、Networktransmission function, etc. The main frame of this system design is:1. Thefront-end detection: through the front-end equipment to collect related data.2information processing: using Microcontrollers to collecting and processinginformation.3. Network transmission: through Ethernet network control chipto pass data to the control center.4. The control center: receiving front-end information, according to thesituation from the disposal of command. This system adopts the main techniquesare:Intrusion detection, smoke detection, Microcontrollers informationprocessing, Microcontrollers network transmission, give orders and thefront-end equipment, central control room.Compared with other security system in the process of research,there is a lot of equipment normal, not cooperate with each other, this design mainly realizing the unity of all the devices will eventually informationsummary to the control center, by the control center for all unified controland processing personnel and equipment. Also in the whole development process,the choice of equipment from the simple, easy to operate, cost-effectiveequipment selection. Vigorously play system equipment utilization, reduceartificial participation, it can improve the accuracy of the incident disposalat the same time also can reduce personnel workload, save the money. On theother hand,Network transmission also try to use the college network centerhas set up the network, reducing additional network construction.Control center in the whole system has a crucial role in thedevelopment, so this article describes in detail the control center toimplement the specific function, especially in video monitoring module, fullytake into account, the backup data, generate security report, power-offprotection, the scene changes, have to consider. Control center location set,also do a thorough reasoning, near to the control center set in the centerof the network, so can not only improve the network transmission rate, andable to work in a timely manner and network center personnel timelycommunication to solve the problem, determined by the location of the toincrease the efficiency of the whole security system to the maximum. The systemfully consider the save construction costs, in the process of equipmentselection, and networking, selecting good cost performance, relatively lowprice products. Fully consider the security staff, professional and technicallevel is not high, not enough skilled to the operation of the equipment, sothe selection of structure simple easy to operate, easy to training to masterthe equipment to serve the whole system.Given the key to deal with problems of security personnel, thedesign will also how to transfer information in a timely manner to the securitypersonnel were studied. The entire campus to form a comprehensive,three-dimensional protection system, to ensure the safety of students and teachers. Single chip microcomputer, we still have some defects in itsfunction, in the process of building a follow-up, considering to theimprovement of the hardware and software to make up for this issue. The useof the wireless network is the system upgrade next, one of the main researchthrough the use of a wireless network can better allocate personnel timelyand found the problem.
