Or in case of emergency, press the emergency alarm button, and alarm signal will be sent to audible and visual alarm and give audible and visual signal to indicate the intrusion position. In this way, the security personnel can dispatch the alarm and improve their control capacity of technical protection. The large screen-wall in the security control center will show the location of intrusion so that security personnel on duty can timely observe the intruder’s movement and inform the nearest security patrol officers to reach the scene. Meanwhile, they can effectively direct staff to take action through the CCTV system timely switching the position of the intruder.
方案说明 Program description
（一）移动探测器 I Mobile detector
Mobile detectors shall be installed in all protective areas in the factory. These detectors shall be placed in pairs along the shape of the perimeter. For the consideration of the influence of attenuation and adverse climate, the distance between each pair shall be calculated 60％－75％ of the theoretical distance. For example, the actual installation distance for 100m nominal of infrared radial should be in the range of 60-75m.
Dual-beam infrared light is employed in the mobile detector to avoid false alarm caused by fallen leaves or little birds. Meanwhile, the mobile detector is equipped with environment identify system so that it can automatically reduce sensitivity under poor weather to minimize systematic false alarms.
控制中心 II Control center
The control center is equipped with an alarm CPU host. Through communication interface modules, alarm linkage with CCTV system and alarm recording can be realized in all protective areas. The central host is also equipped with monitoring and management software which can provide electronic map management. By automatical or manual arming and disarming, the control center can provide all-around observation, realizing in the true sense the combination of anti-matter, anti-person and anti-technology to nip accident in the bud.
When the infrared radial detector detects illegal climbing or actions, it will be activated and give out alarm signals. When the security personnel receives the acoustic-optical signal sent from the alarm management system, the camera in the corresponding place will automatically control the switch to the large screen so as to timely monitor the video in the alarm position. In this way, the nearest security patrol officers can reach the scene and handle the emergency there, and dispatching security personnel to the spot for reinforcement, or call regional 110 through special line.
CCTV系统方案 CCTV System Scheme
CCTV system (Closed Circuit Television System) is a computer-controlled image matrix switching system. By use of CCTV system console, operators can select various cameras and present the images on the image monitor used. CCTV system can automatically manage external alarm signals and present pictures in the selected monitor according to program. The system can monitor the image signal level of the camera. And if there is camera failure, CCTV system will timely send out alarm and make record of the failure. The peripheral equipment of CCTV system can take linkage control by auxiliary communication interface system. The broadcasting system, for example, can also be controlled by CCTV system console. The system can also be used in other occasions, including interlocking joint with intelligent security system or networking with other systems (fire system). The video employs DVR which applies D1-format 16 30f/s totally real hardware video machine. The storage capacity of system configuration can allow 30 days of record-keeping time.
Television monitoring system can be effectively linked with access control system and alarm system. The front detector can activate the alarm host, and further link with the hardware host for video recording and alarm signal sending. It can automatically switch the pictures to the designated monitor according to needs and automatically record the pictures and recheck them; the television pictures can present the number, date, location and date, etc, realizing manual or automatic switch. Digital mode shall be applied in picture recording and storage; all the system controls are centrally managed in the control center.
The pictures on the local hard disk video host can be transferred to sectors related through network for remote monitoring.
监控流程 Monitoring procedure
The multi-channel video signal in the front of the factory video camera is transmitted to the video matrix and hard disk video machine of the monitoring center. Every channel of signal shall be separated into two lines by video distributor, one for recording in hard disk video machine and the other for switching in video matrix. For the reason that the video camera is far away from the central equipment room, optical fiber transmission is used to transmit it to the central equipment room, and it is linked with the perimeter systems.
Television monitoring system employs video matrix and is equipped with multi-media graphic monitoring software. The matrix system has super central micro-processing chip which allows free switch, PTZ camera control, system programming and many action authorization, etc. For example, transfer any picture to any monitor on the screen wall, control rolling, pitching, zoom, several pre-positions, PTZ automatic rolling and random scanning, etc of PTZ or speed dome cameras.
The video matrix control system is established linkage with anti-theft alarm system and access control system through system integration, not needing a lot of alarm input modules. In case of alarm, the video matrix control system receives alarm by communications, and the monitors on the television wall will show pictures of the alarm location as well as the related entrances by automatic switch, and meanwhile the video camera will keep a real time record of the alarm pictures; if more than one alarm happens at the same time, the multi-media integrated computer will real time show the alarm location pictures in parade so that the personnel on duty can be informed of the spot situation in the quickest way.

Set of parties, hanging straight, make ash cake: find the custom before plastering, i.e., find the squares of the four corners, the level of the straight line, pop out the baseline, dado and skirting. Check the flatness and verticality of the wall cylinder by plug. In places where the squareness deviation of the internal angle is too big (can be regulated by square ruler), do the ceiling and make ash cake after approximately determining the plaster thickness (the thinnest being no less than 7mm). While for rooms of face bricks and ceiling roof, the room shall be squared first. Generally pop out cross line as the baseline on the ground, and then preparing ceiling for ash cake making after determining plaster thickness according to the flatness and verticality of the wall. Make standard cakes on the left and right wall corners when plastering, and then make standard cakes at the bottom corners by vertical line hanged by line hammer. Pull a pass line across the standard cakes between the right and left wall corner. Make up several ash cakes about each 1.2m-1.5m above and below the external angles of the door and window exit.
墙面冲筋：等灰饼结硬后，使用与抹灰层相同的砂浆，在上下灰饼之间做宽约30-50mm的灰浆带，并以上下灰饼为准，用压尺推平，冲筋完后应待其稍干后才能进行墙面底灰作业。 Flush the muscle on wall surface: When the ash cake solidified, make a mortar belt of 30-50m in width between the upper and lower ash cakes, and compact level by pressure bar according to the upper and lower ash cakes. Bottom ash work shall start only after muscle flushing has been finished and the wall has been dried.
Angle protection: Straight hang and fix the guiding rule on both sides of the external angle according to the gap between ash cakes and wall beside door frame after squaring by square ruler. Make cement mortar protective angles, and build a small round angle by external angle float. Finally, cut off and clean up the excessive mortar at an oblique angle of 400° 500mm outside the external angle sides.
Base and middle layer plastering: Plaster the base layer on the condition that the wall is sprinkled. Smear the concrete wall with a coat of some 2mm concrete interface treating agent, and then plaster the base, maintaining the thickness at 5~7mm. after the base plaster has been dried, plaster the middle layer at the same way, maintaining the thickness best at 7-9mm. If the middle plaster is too thick, it shall be sufficiently smeared and then scratched to find squares and grinded by wood grinding board by scratcher according to muscle flushing. After the middle layer has been completely smeared and smoothed, exercise overall checks to the verticality, flatness and whether the internal/external angles are square, leveled or straight. Conduct remedial treatment if any problem is discovered.
Surface plastering: Surface plaster can start after the base layer has been 60-70% dried. If the base plaster is too dried because the down time is too long, sprinkle with water, twice smear the plaster and compact it. When the layer has been slightly dried, timely close the light when “closing the body”. The surface shall be free of bubble, spoon mark or uneven joint. The internal angle converged by the ceiling floor, wall edge and side beam shall be at the same horizon, while the convergence of the side beam, cylinder and the beam edge shall be at one vertical line.

In light of concrete conditions, lay joist and suspension point on the undersurface of floor according to design drawings.
Determine elevation reference line of floor and ground and shake it in gray line to the surrounding walls.
Determine ceiling elevation which is based on detailed design and subject to elevation reference line of floor and ground. Shake lines on the wall with horizontal deviation of no more than ±5m.
Determination of ceiling symmetry axis and symmetrical arrangement of joist and suspension point should be done if the ceiling design requires certain shape or pattern.
Shake elevation line of floor and ground in accordance with design around the room.
Shake big-size luminaries and suspension point in accordance with design.
Material for derrick joist: aluminum alloy joist of 15/16in size, the variety, size and pattern of all joists all conform to detailed design requirements.
Drill holes on the under plate of floor with percussion drill and fasten stainless steel lifting bail plate in the center of derrick with 10mm stainless steel dilating screw. The lifting bail should be located correctly without displacement. Weld 10mm stainless steel derrick onto lifting bail after the fixation of lifting bail plate. There should be screw thread at the bottom of derrick. The distance between derricks is 1200mm and the distance between derrick and the top of main joist should be no more than 300mm, otherwise there should be derricks added.
