Industrial scenarios have strict requirements on the reliability, anti-interference and compatibility of communication modules. Bluetooth technology adapts to these requirements through the following features:
Low power consumption and long battery life: Using the LE Coded PHY mode of Bluetooth 5.0+, the module sleep current can be as low as 0.5µA, supporting battery-powered devices to operate stably for more than 5 years in harsh environments.
Anti-interference and stability: Through adaptive frequency hopping (AFH) and 2.4GHz frequency band spread spectrum technology, the communication success rate can be maintained at ＞99.9% in strong electromagnetic interference environments such as motors and inverters.
Multi-protocol fusion: Support the coexistence of protocols such as Bluetooth Mesh, Zigbee, Thread, etc., and achieve seamless docking with industrial buses (such as Modbus and Profinet).
Typical integration solutions
Equipment status monitoring solution
Architecture: Deploy Bluetooth sensor nodes (such as temperature, humidity, and vibration sensors) → Bluetooth gateway (support Mesh networking) → Cloud platform data analysis.
Application: A certain automobile production line collects machine tool vibration data in real time through the EBYTE EWD104-BT57(485) module, with an abnormal warning response time of <1 second and a 25% reduction in failure rate.
Core module: EWD104-BT57(485) supports direct connection with industrial equipment via RS485 interface, with a transmission distance of 300 meters (line of sight), and supports Modbus protocol transparent transmission.
Asset tracking and positioning solution
Technology: Based on Bluetooth 5.1 AoA/AoD positioning, combined with UWB fusion algorithm, the positioning accuracy reaches 30 cm, supporting real-time tracking of large assets such as forklifts and racks.
Case: A certain intelligent warehousing project uses EBYTE E104-BT11N positioning tags, and cooperates with 10 base stations to achieve full coverage of 10,000 square meters of warehouses, and improves asset inventory efficiency by 80%.
