How Bluetooth AOA positioning technology improves factory safety

In the field of industrial manufacturing, factory safety has always been a core issue. With the rapid development of the Internet of Things and intelligent positioning technology, Bluetooth AOA (angle of arrival) positioning technology has become a key tool for improving factory safety management with its high precision and low power consumption. This article will analyze how Bluetooth AOA positioning technology can reconstruct the factory safety system from four dimensions: dangerous area monitoring, equipment operation safety, employee behavior management, and emergency response optimization.

Intelligent monitoring and early warning of dangerous areas

Bluetooth AOA positioning technology can achieve real-time monitoring of dangerous areas in factories by deploying base stations and employees wearing tags. For example, in high-risk areas such as robot operation areas and high-temperature areas, the system determines whether personnel have entered restricted areas based on tag location data. When personnel approach a dangerous area, the system triggers an audible and visual alarm and pushes a notification to the manager's terminal, effectively reducing violations. Chemical plants can use this technology to monitor the distribution of personnel in hazardous chemical storage areas in real time, and combined with the electronic fence function, the misentry rate can be reduced by more than 90%.

 

Enhanced equipment operation safety

Bluetooth AOA positioning technology realizes remote and intelligent equipment operation through the linkage between equipment and tags. For example, in the precision equipment operation scenario, employees need to pass the tag authentication within the specified range before the equipment can be started. The system can record the identity, time and location of the equipment operator to form an operation log. Through this technology, a certain automobile manufacturer has reduced the accident rate of equipment misoperation by 65%, while reducing the frequency of employees' contact with dangerous equipment and reducing the risk of work-related injuries.

 

Employee behavior data management and efficiency improvement

Bluetooth AOA positioning technology can track the movement trajectory and residence time of employees in the factory and generate a behavior heat map. Managers can optimize production processes and personnel allocation by analyzing data. For example, in the assembly line, the system can identify the length of time employees stay at key workstations and determine whether there are operational bottlenecks. Through this technology, a certain electronics factory has reduced the ineffective walking distance of employees by 40% and increased production efficiency by 22%. In addition, the system can be combined with the electronic fence function to prevent employees from leaving their posts or entering unauthorized areas without authorization.

 

Emergency response process optimization and resource scheduling

Bluetooth AOA positioning technology can achieve rapid positioning and resource scheduling in emergency scenarios. For example, in a fire or leakage accident, the system quickly locks the location of trapped employees through tag location data and generates the optimal escape route. At the same time, the system can dispatch the nearest rescue personnel and equipment to the accident site. A chemical park has shortened the emergency response time to less than 3 minutes through this technology, and the rescue efficiency has increased by 70%. In addition, the system can record the location data of personnel before and after the accident to provide a basis for accident investigation.

 

Bluetooth AOA positioning technology reconstructs the factory safety management system through four dimensions: dangerous area monitoring, equipment operation safety, employee behavior management, and emergency response optimization. Its centimeter-level positioning accuracy and low power consumption characteristics make it adaptable to complex industrial environments. With the reduction of technical costs and algorithm optimization, Bluetooth AOA positioning technology will be further integrated with 5G, AI and other technologies to promote the upgrading of factory safety management to intelligent and data-based directions.
