Abstract: With the development of Building Automation System (BAS), Communication and Network Automation System (CAS), Office Automation System (OAS), and the emergence of Intelligent Building Infrastructure (IB), and with the advancement of video compression technology (MPEG4) and the increasing maturity of network technology, the establishment of an integrated system managed by computer systems requires a cost-effective, efficient, digital, networked, and intelligent security monitoring system, which has attracted the attention of many company leaders.
Project Overview
The factory is located at the salient of the Xiamen-Zhangzhou-Quanzhou golden triangle region. It covers an area of more than 60,000 square meters and is mainly engaged in the production of electronic components.
With the emergence of the intelligent building construction boom, and the technological trend combining computer technology, control technology, communication technology, and CRT display technology, Building Automation Systems (BAS), Communication and Network Automation Systems (CAS), and Office Automation Systems (OAS) are emerging as new microcosms of intelligent building infrastructure (IB). Furthermore, with the development of MPEG4 video compression technology and the increasing maturity of network technology, establishing an integrated system managed by computer systems requires a cost-effective, efficient, digital, networked, and intelligent security monitoring system, attracting significant attention from many company leaders.
Design Background
The overall request from the evidence company, based on the application of the latest scientific techniques and advanced equipment, and in conjunction with the factory's objective situation and structural environment, is to achieve 24-hour monitoring of all entrances and exits, storage workshops, and external passages; to statistically analyze the container vehicles entering and leaving each container terminal; and to implement an anti-theft and anti-intrusion security system to meet the needs of factory security supervision and warehouse management. It can also monitor emergency exits in the storage workshops to ensure all passages are unobstructed; and to capture evidence of unauthorized entry and exit, effectively deterring such incidents and preventing various theft and damage incidents; and to integrate a background music broadcasting system to prevent potential or impending incidents from occurring, thus minimizing the impact of incidents. This achieves the goal of intelligent security management.
System Design
Three-way variable cameras were installed around the factory area to monitor key areas surrounding the factory and buildings. Company leaders, security personnel, and...
1. The relevant components can view the entire dynamics of the factory on the computer; and can perform relevant control on the camera (such as: remote control of the pan, tilt, and zoom in all directions; control of image zoom, zoom out, zoom in and out, etc.).
2. Install electronic door magnetic security alarm devices at each emergency exit within the factory area. The system has the function of setting up alarm locations; and can be armed and deactivated on the computer, as well as view relevant event records and status displays.
3. Install (16) intelligent ground sensor parking management systems in the parking direction of the container terminal, which have the function of displaying vehicle entry and exit status (with shape electronic display screen); and can view the records of container entry and exit time and cargo handling time through the computer.
4. Install a one-to-one intercom system next to the container terminal to enable external drivers and internal warehouse management personnel to communicate; install rotating flashing warning lights and high-quality sound columns in a prominent central location inside the factory to achieve simultaneous sound and light warning effects.
5. Install a background public address system throughout the factory area and integrate it with a closed-circuit television monitoring system. When suspicious personnel are detected, the system can be activated to disperse personnel in individual or all areas to prevent incidents or accidents from occurring.
6. The system can manually or artificially capture and record images on-site, and can perform dynamic recording of fixed points or partial areas. It can obtain true, clear, and solid images of the maximum extent, which can be enlarged and played back.
7. The monitoring screen allows setting a fixed screen or manually scheduled screen switching. In the giant array section of the TV wall (24 21" color dividers), it is possible to freely switch between more than 80 cameras via a smart keyboard. If it is an all-in-one intelligent camera, its related controls can be controlled.
8. All front-end components and equipment in the system use spherical protective covers, except for embedded hemispherical protective covers used in the office area. All of these have specific anti-damage functions.
9. The equipment used in the system must comply with national regulations. It will not cause interference, radiation, or other adverse effects, and will not compromise the safety of existing equipment and facilities in the factory area.
10. Construction Must Meet Standards. Generic Cabling System (GCS) cabling must be used, and the cabling must comply with international standards to fully guarantee the high-speed operation of system equipment and the proper and robust transmission of information. Cables must not be directly exposed where low-voltage cable trays are unavailable; they must be installed in high-density conduits or fitted with rust-proof flexible metal conduits (short intervals). Conduit routing must be standardized and orderly, and installation must be secure; protective measures such as sun protection, waterproofing, pressure resistance, and explosion protection must be in place.
11. The system's versatility, compatibility, and real-time performance: the system must reserve sufficient time for expanding image interfaces, control interfaces, alarm interfaces, etc., so as to facilitate future system expansion and upgrades and further improve system performance.
12. System security and confidentiality. All program controls and computer controls within the system have security measures to prevent unauthorized access, thus ensuring excellent confidentiality for system equipment and materials.
Business standards that structured cabling systems should meet:
ISO/IEC 11801 "Information Technology - Cabling Standards"; CECS72:95 "Design Specification for Integrated Cabling Systems in Buildings and Building Complexes"; GB/T-50314-2000 "Design Standards for Intelligent Buildings"; DBJ 13-32-2000 "Design Standards for Building Intelligent Systems"; DBJ 13-44-2000 "Quality Inspection Regulations for Building Intelligent Systems"; GA/T 367-2001 "Technical Requirements for Video Security Monitoring Systems"; GA/T 368-2001 "Technical Requirements for Intrusion Alarm Systems"; GA 308-2001 "Optometry Rules for Security Systems".
System composition
Sixteen SONY FCB-EX480AP low-light cameras were installed around the factory perimeter. These cameras have a resolution of 460TV and feature electronic shutters and backlight compensation. Sixteen outdoor intelligent dome cameras with covers and 16 RS-485/232 decoders were also installed, connected to the main control unit via a two-wire bus. Sixty-four SONY TCO-C480 low-light cameras were installed in the internal emergency exits, passageways, and storage areas. Sixteen MC series door magnets were installed at the factory's emergency exits, and 24 pairs of SEN30LL and HA series automatic digital variable-value dual-beam infrared detectors were installed near the container terminal. The alarm control unit uses the Canadian "Maple Leaf" PA-DEC2 digital alarm transmitter, connected to the computer via its digital communication module.
