With the increasing number of students and faculty, it is more and more difficult to rely on traditional civil air defense methods for management. Therefore, if the school is equipped with corresponding technical defense facilities to make up for the shortage of civil air defense, civil air defense+technical defense can improve the safety factor. Now we need to design and install a campus monitoring system according to the actual situation of the whole campus, and we need to realize the following functions.
Take panoramic photos of all areas and public places on campus, realize all-round monitoring of the school, and resolutely put an end to incidents such as theft of student dormitories, loss of bicycles, destruction of public property such as libraries and laboratories, and riots in restaurants and sports fields;
Long-term video recording and alarm triggering video recording provide the basis for quick case solving in the later period;
Reduce a large number of school personnel expenses and personnel patrol, achieve the combination of static and dynamic, and effectively save school expenses;
Optimize the campus safety environment and students' self-discipline;
School leaders can monitor the monitoring screen at any point in real time through any terminal computer in the network, keep abreast of the scene and master the first-hand information;
With the help of school video surveillance, we can clean up the chaos around the campus and make the campus peaceful.
Design principles and basis of school monitoring system;
The scheme design of this project follows the principles of advanced technology, complete functions, stable performance and cost saving. Considering the construction, maintenance and operation factors comprehensively, there will be room for future development, expansion and transformation.
progress
If the investment cost of the school allows, the system adopts today's advanced technology and equipment. On the one hand, it can reflect the advanced level of the system, on the other hand, it has strong development potential, so that the system can adapt to social development as long as possible.
reliability
The most important thing of school monitoring system is reliability. Once the system is down, the consequences are unimaginable. Therefore, the system must run reliably and continuously. Under the condition of acceptable cost, the system design is strictly required from the aspects of system structure, equipment selection, technical service and product supplier's maintenance response ability, so as to make the possibility of failure as small as possible. Even if a fault occurs, the affected area should be as small as possible.
safe
The security performance of the security system itself can not be ignored. When designing the school monitoring system, we must take various measures to prevent illegal destruction of the system in various forms and ways.
expansibility
The future development needs should be fully considered when designing the system, and the system should have the possibility of expanding and upgrading the spare capacity.
standard
Because this system is a strict comprehensive system, we should refer to various standards and specifications in the process of system design and construction, strictly abide by various technical regulations, and do a good job in standardized design and construction of the system.
Solution:
After what you have described above, this monitoring system needs to cover parking lots, bicycle sheds, north and south school gates, main roads and student apartment gates, with a total of 32 monitoring points. The monitoring center is located in the south gate guard duty room, and all monitoring images are transmitted to the south gate guard duty room for display and storage. In order to meet the monitoring effect, a TV wall is set up in the south guard duty room, and all monitoring pictures can be freely rotated or switched to the wall.
Introduction of school video monitoring system scheme
According to the field situation of the school, the reform scheme is divided into four subsystems: front-end acquisition, transmission, display and storage. The following is a detailed introduction of each subsystem.
Front-end acquisition subsystem
Acquisition subsystem is the eye of the whole monitoring system. After on-the-spot investigation, two cameras with license plates were set at the two gates of the school, which can clearly record the vehicles entering and leaving the school; Set up 8 infrared guns in each part of the main road of the school to record the flow of people; Set up/kloc-0 infrared high-speed balls with automatic tracking function in the school square, bicycle shed and parking lot, and turn on the automatic tracking function at different times. There are 19 infrared hemispheres on the stairs of the teaching building and at the entrance of the student apartment.
Transmission subsystem
Due to the large scope of the school, the traditional video cable method can not meet the transmission requirements, so the monitoring points in the campus are transmitted by optical cable, which unifies the monitoring points in several places, and adds an optical transceiver (the optical transceiver needs the reverse data transmission function to transmit the control signal of the ball machine), which is transmitted to the south guard duty room through optical cable. For each monitoring point in the building, because the monitoring signal was transmitted to the south guard in the teaching building before, in order to save investment and facilitate construction, the newly added monitoring points in each building are transmitted from the previous cable to the south guard by video stacker.
Display subsystem
The display system adopts TV wall mode and 8+ 1+2 mode. 8 is eight monitors, which are basically used for rotating display of 32 monitoring pictures, and 1 is a 42-inch monitor, which is used for switching display of important pictures. Two LCD monitors are used to set up two hard disk video recorders and video playback. In order to achieve the purpose of rotary switching, a video matrix with 48 inputs 16 outputs and an operation control keyboard are needed.
Storage subsystem
Two 16 embedded hard disk video recorders are used to store the monitoring images (in order to transmit the monitoring signals to the video matrix, the hard disk video recorders need to have cyclic output function). In order to store 32 images in 30 days, two hard disk video recorders need to be equipped with 10 2T hard disks.
