High Precision Personnel Positioning Solution for Indoor and Outdoor Use in Cement Plants

Ensuring the safety and efficient management of personnel is crucial in the complex industrial environment of cement plants. Introducing ultra wideband (UWB) positioning technology, combined with specific positioning base stations and devices, can provide high-precision indoor and outdoor personnel positioning solutions for cement plants.

1、 Requirement analysis

1.Security requirements

There are many potentially hazardous areas in cement plants, such as high-temperature equipment areas, material conveyors, large rotating machinery, etc. Real time positioning of personnel can promptly detect situations where they accidentally enter dangerous areas and issue alerts, avoiding the occurrence of safety accidents.

In emergency situations such as fires, explosions, etc., it is possible to quickly determine the location of personnel, provide accurate information for rescue work, improve rescue efficiency, and ensure the safety of employees' lives.

2. Production management requirements

Understand the distribution of employees within the factory area, arrange work tasks reasonably, and improve production efficiency. For example, during equipment maintenance, it is possible to quickly find suitable technicians and determine their location, reducing maintenance time.

Record and analyze employees' work trajectories, evaluate work efficiency, and provide data support for optimizing production processes.

2、 Advantages of UWB positioning technology

1.High precision positioning

UWB technology has centimeter level positioning accuracy, which can accurately determine the position of personnel indoors and outdoors in cement plants, meeting the demand for precise positioning of personnel.

Compared to other positioning technologies such as Wi-Fi, Bluetooth, etc., UWB has higher positioning accuracy, is less affected by environmental interference factors, and can work stably in complex industrial environments.

2. Strong real-time performance

Capable of real-time monitoring of personnel position changes and providing timely feedback to the monitoring system. In emergency situations, being able to provide the latest personnel location information for rescue work can save valuable time.

3. Strong anti-interference ability

There are a large number of electromagnetic interference sources in the cement plant, such as motors, frequency converters, etc. UWB technology uses ultra wideband signals and has strong anti-interference ability, which can work normally in complex electromagnetic environments.

4. Simultaneous localization of multiple targets

Multiple personnel can be located simultaneously to meet the needs of large-scale personnel management in cement plants. Whether in the production workshop or outdoor yard, it is possible to accurately track the location of each employee.

3、 Product Introduction

1. Ultra wideband UWB positioning base station VDU2503

As the core device of the positioning system, VDU2503 positioning base station is responsible for receiving signals sent by positioning tags and calculating the position of the tags through algorithms.

It has high stability and reliability, and can work for a long time in harsh industrial environments. Installed in key locations of the cement plant, such as workshop entrances, corridors, outdoor storage yards, etc., to achieve full coverage of the entire factory area.

2. UWB positioning wristband VDU1502

Wear it on employees' wrists for easy portability. The VDU1502 positioning wristband can send real-time location information of employees and also has emergency alarm function.

When employees encounter dangerous situations, they only need to press the alarm button on their wristband to send a distress signal to the monitoring system for timely rescue.

3. UWB positioning card VDU1501

Similar to traditional work permits, but integrated with UWB positioning chips. After employees wear their work cards, their location information can be monitored in real-time by the system.

The work card can be integrated with the access control system, attendance system, etc. of the cement plant to achieve multiple uses of one card and improve management efficiency.

4. Safety helmet UWB positioning tag VDU1506

Installed on the safety helmet to ensure accurate tracking of the employee's position in any situation. The VDU1506 positioning tag has the characteristics of waterproof, dustproof, and impact resistance, and is suitable for use in harsh environments of cement plants.

When employees wear safety helmets and enter hazardous areas, the positioning system will automatically sound an alarm to remind employees to pay attention to safety.

4、 System architecture

1.Hardware layer

Composed of UWB positioning base stations, positioning tags (wristbands, work cards, safety helmet tags) and other devices, responsible for collecting personnel location information and sending it to the server.

2. Data transmission layer

Use wired or wireless methods to transmit the data collected by the positioning base station to the server. In cement plants, suitable transmission methods such as Ethernet, Wi Fi, 4G/5G, etc. can be selected according to the actual situation.

3. Server layer

Responsible for receiving and processing positioning data, running positioning algorithms, and calculating personnel position coordinates. At the same time, the server also stores historical location data for subsequent analysis and querying.

4. Application layer

Provide users with a visual monitoring interface that displays personnel location distribution, trajectory playback, alarm information, and more. The application layer can be integrated with other management systems in the cement plant to achieve functions such as personnel management, safety monitoring, and production scheduling.

5、 Implementation steps

1.On site investigation

Conduct a comprehensive on-site investigation of the cement plant to understand its layout, building structure, equipment distribution, and determine the installation location and quantity of positioning base stations.

2. Equipment installation and debugging

According to the survey results, install UWB positioning base stations, tags and other equipment, and conduct debugging to ensure the normal operation of the system. During the installation process, attention should be paid to the waterproof, dustproof, anti-interference and other performance of the equipment to ensure stable operation in harsh industrial environments.

3. System integration

Integrate the positioning system with the access control system, attendance system, monitoring system, etc. of the cement plant to achieve data sharing and linkage control. For example, when an employee passes through the access control, the system can automatically record attendance information and update personnel location information at the same time.

4. Training and usage

Train the management personnel and employees of the cement plant to familiarize them with the use and precautions of the positioning system. After the system is officially put into use, it should be regularly maintained and upgraded to ensure its stability and reliability.

6、 Benefit analysis

1. Improve the level of safety management

Through real-time positioning and warning functions, it effectively prevents personnel from mistakenly entering dangerous areas and reduces the probability of safety accidents. In emergency situations, it is possible to quickly determine the location of personnel, improve rescue efficiency, and ensure the safety of employees' lives.

2. Improve production management efficiency

Understand the distribution of employees within the factory area, arrange work tasks reasonably, and improve production efficiency. Record and analyze employees' work trajectories to provide data support for optimizing production processes.

3. Realize intelligent management

The integration of positioning system with other management systems has achieved intelligent management of cement plants. By using functions such as one card for multiple purposes and data sharing, management efficiency has been improved and management costs have been reduced.
