RFID factory personnel positioning solution

1. Overview of the Plan

The factory personnel positioning monitoring system needs to collect, distribute, monitor, and summarize the location and image information of workers. The transmission of system equipment is carried out through Ethernet, and the positioning data and video signals are transmitted to the central control center through IP local area network. The real-time dynamic distribution of personnel, real-time monitoring, illegal intrusion alarm and other interfaces are visually displayed through the TV wall, and the system data is centrally stored for up to one month (30 days).

2. System Design

2.1 System positioning

Based on the real needs of users, our design team has jointly discussed and determined the factory personnel positioning monitoring system with users:

1. The system has the characteristics of economy, reliability, progressiveness and sustainable development;

2. Emphasize the reliability of the system, ensure the stability and reliability of advanced systems with high starting points in future applications, and enable long-term uninterrupted and fault free operation;

3. Emphasize the economy of the system, use new technologies and products to build new systems, simplify the difficulty and links of system construction, improve the integration of subsystems and even components, and effectively and reasonably reduce the average cost of system construction;

4. Emphasize the practicality of the system, focusing on user security prevention and business operations. The system serves practical needs, specifically in detecting potential hazards and handling emergency situations;

5. Emphasize the linkage of the system, combine real-time personnel trajectories with monitoring systems, and achieve the function of positioning and alarm linkage on one platform. Utilize the intelligent and automated features of the platform to reduce the intensity of human monitoring while improving the system's warning capabilities, in line with the materialist concept of "letting machines replace humans to complete tedious work";

6. Emphasize the sharing of system resources, making the system constructed in this project a three-dimensional, multi-level, all-round, and defensive personnel positioning and monitoring system. The open software platform lays a solid foundation for the secondary utilization and sharing of system resources.

2.2 Design Highlights

High speed alarm response: By implementing dynamic distribution through RFID staff and setting security levels for critical areas, unauthorized personnel invading critical areas can quickly trigger alarms for personnel information and image data, achieving rapid dynamic response;

24/7 monitoring function: Through the installation of 24/7 monitoring equipment, imaging is carried out 24/7 to monitor the safety status of indoor and outdoor intersections and the perimeter of the factory in real time;

Flexible point layout: Due to the diversity of application methods in the factory area, RFID sensors and surveillance cameras will also change accordingly, enabling comprehensive monitoring. In terms of layout, some positions use hemispherical network cameras, some positions use gun network cameras, and some positions use network high-speed balls, which are not limited by installation locations and have the characteristics of flexibility, convenience, stability, and reliability.

Centralized storage function: All video images are stored centrally within IP-SAN, scientifically and securely.

Centralized management and command function: The software adopts a B/S architecture design, which can be accessed in real-time through a browser in the command center or leadership office, enabling real-time monitoring of staff location information, image information, emergency tracking, location information playback, alarm processing, and permission allocation;

Replay query function: In case of emergencies, the activity information and images of on-site personnel can be accessed in a timely manner and recorded in real-time. The time and location of the event can be recorded, and relevant departments and personnel can be alerted and coordinated for processing. Afterwards, the event can be queried and analyzed;

2.3. System composition

The personnel positioning monitoring system can be summarized as consisting of a front terminal system, a transmission subsystem, a storage subsystem, a display subsystem, and a control subsystem.

(1) Front terminal system

RFID sensors, IP network cameras, and poles distributed at various monitoring points of LNG ships under construction.

(2) Transmission subsystem

The transmission network deployed within the factory adopts Ethernet as the backbone network transmission for this monitoring system.

(3) Storage subsystem

The IP-SAN network disk array deployed in the computer room provides storage services to the front-end terminal system due to centralized storage mode. And provide data retrieval and playback services for the monitoring center and sub control clients.

(4) Display and Control Subsystem

The TV wall, servers, decoding platform, computers, and management software deployed in the monitoring center are used for centralized monitoring and management. In this system, staff use them to complete monitoring and control functions.
