Monitoring design scheme of civil air defense basement in Nanyuan West District
I. Introduction
Video surveillance system is an important part of security technology system, an advanced and comprehensive system with strong defense capability. It can directly watch the situation of the monitored place through the camera and its auxiliary equipment (lens, etc.). ) at a glance, at the same time, it can record all or part of the images of the monitored place, which provides convenient conditions and important basis for dealing with some events in the future. At the same time, the TV monitoring system can also cooperate with other security technology prevention systems such as anti-theft alarm, which has stronger prevention ability and can find hidden dangers of accidents and incidents in time, prevent damage and avoid adverse effects.
Second, the project overview
In recent years, with the rapid development of social economy and science and technology, the living standards of urban and rural residents have been significantly improved, and basic living conditions such as food, clothing, housing and transportation have been continuously improved. With the gradual acceleration of urban development, people's demand for private cars is increasing, and the density of vehicles has become a major landscape in the world. At this time, the development of residential areas needs to be equipped with corresponding underground parking lots. In order to save space on the ground and not occupy the original green belt, most residential areas are located in the underground of each residential building. Underground parking lot (garage) is equipped with vehicle access management, video security monitoring, electronic patrol, emergency alarm and other systems. Cameras should be installed at vehicle entrances and exits, main pedestrian walkways and personnel entrances and exits of underground parking lots (garages) to clearly display facial features. Because there are few people underground, this has caused certain security risks to vehicles and given criminals an opportunity. In addition, when vehicles collide, there is not enough evidence to distinguish right from wrong, so it is difficult to cover all aspects only by the property management personnel. Therefore, the installation of video surveillance system can solve these problems and assist property personnel to manage these vehicles statically. It can not only monitor the scene in real time, find the situation in time, but also record every link.
The underground parking lot in a residential area is built underground, and the entrance and exit are set separately. All the cameras are infrared cameras because of the poor light at the scene. After all the images are transmitted to the monitoring room, there is a 16 embedded hard disk video host for data storage, and at the same time, the display is switched through a 2 1 inch monitor.
Setting requirements of video security monitoring system:
Small underground parking lots (garages) should be equipped with cameras at the following locations:
A) Vehicle entrances and exits of underground parking lots (garages) connected with the outside world;
B) Main pedestrian passage of underground parking lot (garage);
C) Personnel entrances and exits connected with underground parking lots (garages);
D) Set the location according to the needs of safety management.

Second, the project overview
In recent years, with the rapid development of social economy and science and technology, the living standards of urban and rural residents have been significantly improved, and basic living conditions such as food, clothing, housing and transportation have been continuously improved. With the gradual acceleration of urban development, housing is getting farther and farther away, people's demand for private cars is increasing, and the density of vehicles has become a global landscape. At this time, the development of residential areas needs to be equipped with corresponding underground parking lots. In order to save the above-ground space, under the condition of not occupying the original green belt, most communities have set up underground parking lots for residents on the ground floor of each residential building. Because there are few people underground, this has caused certain security risks to vehicles and given criminals an opportunity. In addition, when vehicles collide, there is not enough evidence to distinguish right from wrong, and it is difficult for the property manager to cover everything. Therefore, the installation of video monitoring system can solve these problems and assist property management personnel to manage these vehicles statically. It can not only monitor the scene in real time, find the situation in time, but also record every link as strong evidence to solve the problem.

5. 1, system function description
In this video monitoring system, the embedded hard disk video recorder is selected as the control core of the system. All video images in the system are transmitted back to the monitoring room, connected to the embedded hard disk video recorder and stored by installing a corresponding number of hard disks. 16 channels of video input configuration, each channel can be recorded at the speed of 1-25 frames per second, and H.264 compression technology is adopted to make the image clearer and the details more realistic. Using video mobile alarm recording can save a lot of hard disk space. Video recording, playback and monitoring are all real-time, and you can control the pan/tilt, lens and so on. The remote monitoring function can be realized through the network. The recording time depends on the capacity of the hard disk, and a large hard disk system is adopted in the system, which can meet the technical requirements of video data storage put forward by users.
The system undertakes the task of real-time monitoring all visual places. All front-end 16 cameras are directly connected to 1 16 embedded hard disk video recorder, and each hard disk video recorder is equipped with two 1000G hard disks, which can store video data for one month.
At the same time, a 2 1 inch monitor is specially installed to facilitate the monitoring of the personnel on duty, and the 16 screen is displayed in turn, which is convenient for the personnel on duty to know the underground parking lot in time.
5.2, system components
According to the project requirements put forward by customers, a complete video monitoring system scheme is formulated, which is mainly composed of front-end video acquisition part, video signal transmission part, display and storage part.
5.2. 1, video capture section
The camera part is the front part of the TV monitoring system and the "eye" of the whole system. It is arranged in a certain position of the monitored place, so that its field of vision can cover all the monitored parts. Sometimes, the monitoring area is very large. In order to save the number of cameras, simplify the transmission system and control display system, install appropriate lenses on the cameras to make the scenes observed by the cameras clearer.
A total of 24 cameras are installed in this network video surveillance system, including 12 mobile points and 12 fixed points. Their distribution positions are as follows:
Serial Number Installation Location Equipment Type Quantity Unit
1 special camera for entrance license plate shooting 1.
2. There are 1 cameras dedicated to license plates at the exit.
3. 50-meter tunnel and parking space in underground parking lot 10 infrared camera.
Four infrared high-speed global cameras in the underground parking lot 12.
The four-corner infrared constant-speed global camera of the underground parking lot is equipped with a camera dedicated to shooting license plates at the entrance and exit of the underground parking lot. The model is KV-C3055CP, with infrared light and strong light suppression function. It is mainly used to monitor the vehicles entering and leaving the underground parking lot, which can clearly record the license plate numbers of the vehicles entering and leaving, so as to facilitate the query of the entry and exit time of specific vehicles in the future, thus strengthening the management of vehicles.
10 50m infrared camera, model KV-C3085, installed in the tunnel and parking space of underground parking lot, equipped with infrared light. When the light is bad, they will automatically turn into black and white pictures, and the infrared lights will automatically turn on. The main purpose is to monitor the traffic situation and parking position of vehicles in the underground parking lot, and whether other vehicles are scraped or intentionally damaged by other personnel, so that the personnel on duty can find out the situation in time.
In addition, an infrared constant-speed global camera (model KV-C8609R-SN480) is installed in the four corners of the underground parking lot, which is a global spherical camera with infrared ray and built-in Sony movement, and can rotate to see the specific situation of the whole underground parking lot. When the personnel on duty find problems or suspicious vehicles, they can control the pan/tilt to track and monitor and store videos through the mouse, so that the suspicious elements have nowhere to hide.
In a word, the camera, like the eyes of the whole system, turns the content it monitors into an image signal and transmits it to the monitor in the control center.
5.2.2 Transmission part
The transmission part is the transmission channel of the system image signal. At present, TV monitoring system mostly adopts video baseband (coaxial cable) transmission mode. If the camera is far away from the control center, twisted pair transmission or optical fiber transmission is also used.
This system is a monitoring project of the underground parking lot. The monitoring room is set at the entrance of the underground parking lot, and each camera is close to the monitoring room. The coaxial cable of SYV75-5 is directly used for video signal transmission, which can meet the quality requirements of customers. The key requirement of image signal transmission is that after the image signal passes through the transmission system, there will be no obvious noise and distortion, and the clarity and gray level of the original image signal will not be significantly reduced.
In order to ensure the normal power supply of all front-end cameras, all cameras are powered by 220V from the monitoring room, and then the power supply of 12V and 2A is changed to 12V to supply power to all cameras. All power cables are RVV2x0.752 cables.
RVVP2x0.752 shielded cable is used for control signals of all pan/tilt.
5.2.3. Video signal display and storage part
In this scheme, 1 set 16 embedded hard disk video recorder and monitor are selected to display all camera signals, and the video is recorded through the hard disk. The customer needs to keep the data 1 month. After calculation, the hard disk video recorder needs to be equipped with two 1000G hard disks. After 1 month, the hard disk space will be automatically covered without manual intervention. At the same time, it also supports remote video transmission through the network, which is convenient for relevant personnel to access the local network hard disk video host anytime and anywhere through the network and watch real-time pictures.
For the convenience of the personnel on duty, another 2 1 inch monitor is installed. The hard disk video recorder can automatically switch the patrol display on the monitor through the 16 video switch while storing data.
Six, equipment selection
6.1.100m infrared global camera (KV-C8609R-SN480)
As an innovative patented product, this series of infrared lamps completely solved the night lighting problem of spherical pan/tilt. The horizontal axis linkage mechanism ensures that the light projection of the infrared lamp always coincides with the camera picture, and the arrangement of multi-light field light sources ensures that there is no dead angle in the vertical direction. The cage lamp holder structure makes full use of the space between the upper cover and the interlayer of the spherical holder. Equipped with up to 160 high-power infrared diodes. The actual distance can reach 100 meters.
The lamp tube adopts grouping power supply mode, and the overall failure probability is extremely small; Compared with other single-space structures, the heat dissipation area of large-scale upper sandwich structure is more than 3 times; Each lamp tube is hung independently and mutually independent, and there is no mutual heat collection phenomenon of centralized welding and installation of a single PCB board; Constant current source drive ensures that the infrared lamp works in a single constant current state under any external conditions, effectively avoiding the vicious cycle between temperature rise, negative temperature characteristics of the lamp and current under the constant voltage drive mode widely used today. The above measures provide sufficient guarantee for the high reliability of infrared lamps.
Although the structure is complicated, it is extremely simple to use, and only one set of power cord provides AC24V power. The opening and closing of infrared lamp and the tracking of translation/tilt are completed automatically.
The pan-tilt machine core is connected with the machine body through a quick connecting plate, and an intelligent decoding board or a variable speed decoding board is integrated on the machine core.
