Positioning of Personnel and Equipment in Power Plants: Improving Safety and Management Efficiency

Ensuring the safety of personnel and equipment, as well as improving management efficiency, is crucial in the important energy production site of power plants. The application of personnel and equipment positioning technology has brought a new management mode and security guarantee to power plants.

The demand for personnel and equipment positioning in power plants

1. Security management requirements

There are many dangerous factors in power plants, such as high voltage electricity and high-temperature steam. Once personnel enter the dangerous area or equipment malfunctions, it may cause serious safety accidents. Through personnel and equipment positioning technology, real-time location information of personnel and equipment can be obtained, potential safety hazards can be discovered in a timely manner, and corresponding measures can be taken to prevent them.

For example, when personnel approach the high-voltage equipment area, the system can issue an alarm to remind them to stay away from the dangerous area and avoid electric shock accidents.

2. Emergency rescue needs

Quickly determining the location of personnel and equipment is crucial for timely rescue operations in emergency situations such as fires, explosions, etc. Personnel and equipment positioning technology can help rescue personnel quickly locate trapped individuals and critical equipment, improve rescue efficiency, and reduce casualties and property losses.

For example, in the event of a fire, rescue personnel can quickly determine the location of the trapped person through a positioning system, develop the best rescue route, and ensure that the trapped person can receive timely rescue.

3. Demand for improving management efficiency

Power plants usually occupy a large area, have numerous equipment, and are complex to manage. Through personnel and equipment positioning technology, real-time monitoring and management of personnel and equipment can be achieved, improving management efficiency. For example, managers can use a positioning system to understand the location distribution and work status of staff, arrange work tasks reasonably, and improve work efficiency.

Positioning technology for personnel and equipment in power plants

1. Wireless signal based positioning technology

Wi Fi positioning: Utilizing the existing Wi Fi network within the power plant, the location of personnel and equipment is determined by measuring parameters such as signal strength and arrival time. This technology has low cost and easy deployment, but its positioning accuracy is relatively low.

Bluetooth positioning: Positioning is achieved through signal interaction between Bluetooth beacons and mobile devices. Bluetooth positioning has high accuracy and is suitable for scenarios that require high positioning accuracy, but requires the deployment of specialized Bluetooth beacon devices.

UWB positioning: Ultra wideband (UWB) technology has the advantages of high accuracy, low power consumption, and strong anti-interference ability, and has high application value in the positioning of personnel and equipment in power plants. However, UWB devices have relatively high costs and are also complex to deploy and maintain.

2. Sensor based positioning technology

Inertial navigation positioning: using inertial sensors carried by personnel and equipment (such as accelerometers, gyroscopes, etc.) to measure motion status and determine position through integration calculation. This technology is not affected by environmental factors, but positioning errors accumulate over time.

Pressure sensor positioning: Install pressure sensors on the ground of power plants to determine their location by detecting the foot pressure of personnel and equipment. Pressure sensors have high positioning accuracy, but require a large number of sensor devices and have high costs.

The function of the personnel and equipment positioning system in power plants

1. Real time positioning and tracking

The system can display the real-time location of personnel and equipment within the power plant and track their movement trajectory. Management personnel can monitor the dynamics of personnel and equipment at any time through the monitoring interface, ensuring their activities within the safe area.

2. Security Warning

According to the safety regulations of the power plant, different safety zones and warning levels are set up. When personnel and equipment enter a hazardous area, the system will automatically sound an alarm to remind relevant personnel to pay attention to safety.

3. Emergency rescue

In emergency situations, the system can quickly determine the location of personnel and equipment, providing accurate location information for rescue personnel. At the same time, the system can also be linked with fire and security systems to improve emergency rescue efficiency.

4. Data analysis and report generation

The system can analyze the location data of personnel and equipment, generate reports and statistical charts. Management personnel can use this data to understand the activity patterns of personnel and equipment, optimize workflow, and improve management efficiency.

Application case of personnel and equipment positioning system in power plants

1. A large thermal power plant

The power plant adopts UWB positioning technology to achieve high-precision positioning of personnel and equipment. Management personnel can monitor the real-time distribution and work status of personnel and equipment through the monitoring interface, arrange work tasks reasonably, and improve work efficiency. At the same time, the system also sets up multiple safety zones. When personnel and equipment enter the danger zone, the system will automatically issue an alarm to remind relevant personnel to pay attention to safety. In case of emergency, rescue personnel can quickly determine the location of trapped persons and key equipment through the positioning system, and carry out rescue in a timely manner, reducing casualties and property losses.

2. A certain nuclear power plant

Nuclear power plants have extremely high safety requirements, and personnel and equipment positioning systems play an important role in the safety management of nuclear power plants. The nuclear power plant adopts a combination of inertial navigation positioning and pressure sensor positioning technology, achieving all-round positioning of personnel and equipment. The system can monitor the position and movement status of personnel and equipment in real time, ensuring their activities within a safe area. At the same time, the system is also linked with the safety monitoring system of the nuclear power plant. When abnormal situations occur, it can promptly issue alarms and take corresponding measures to handle them, ensuring the safe operation of the nuclear power plant.

Future Development Trends

1. Technology integration

In the future, the positioning technology for personnel and equipment in power plants will continuously integrate other advanced technologies such as artificial intelligence, big data, and the Internet of Things to achieve more intelligent positioning and management. For example, by analyzing the location data of personnel and equipment through artificial intelligence algorithms, potential security risks can be predicted and preventive measures can be taken in advance.

2. Precision improvement

With the continuous advancement of technology, the accuracy of personnel and equipment positioning will continue to improve. High precision positioning technology will better meet the safety management and emergency rescue needs of power plants, providing more reliable guarantees for the stable operation of power plants.

3. Cost reduction

With the popularization of positioning technology and the expansion of its application scale, equipment costs and deployment costs will gradually decrease. This will enable more power plants to adopt personnel and equipment positioning technology, improving safety management level and management efficiency.

In short, the positioning technology of personnel and equipment in power plants plays an important role in improving safety management level and management efficiency. With the continuous development and application of technology, personnel and equipment positioning technology will play an increasingly important role in power plants.
