Overview
The application of Bluetooth gateways in the field of Internet of Things mainly includes three major application areas: indoor positioning of the Internet of Things, data collection of the Internet of Things, and connection control of the Internet of Things. The following is a detailed explanation of the three major application areas.
1. Indoor Positioning of Bluetooth in the Internet of Things
The application of Bluetooth gateways in indoor positioning includes two major directions: personnel positioning and asset equipment positioning.
a. Personnel Positioning
The Bluetooth gateway is installed in a specific place indoors. Personnel can wear wearable devices such as Bluetooth badges and Bluetooth bracelets. Bluetooth wearable devices broadcast Bluetooth signals. The Bluetooth gateway scans the terminal device signal to achieve indoor personnel positioning. If the wearable device adds the function of human life collection, it can also obtain the vital signs of personnel in real time.
Application scenarios: nursing homes, hospitals, factories, construction sites, schools, mines and other application fields.
b. Asset Equipment Positioning
The Bluetooth gateway is installed in a specific area indoors. Bluetooth beacons or Bluetooth asset tags are installed on important asset equipment. Bluetooth beacons or Bluetooth asset tags broadcast Bluetooth signals. The Bluetooth gateway scans the beacon data of the device terminal to achieve asset positioning management of materials and materials. The background can understand the internal distribution of materials and materials in the indoor space in real time.
Application scenarios: hospitals, factories, warehouses, schools, parks, animal husbandry and other application fields.
2. IoT Data Collection
The Bluetooth gateway is installed in a specific area of the industrial environment. A large number of sensors such as temperature, humidity, water immersion, dust concentration, and light are deployed in the factory area to monitor the environmental data of the industrial site in the factory area in real time. Various sensor data are reported through Bluetooth broadcasting. The Bluetooth gateway scans the mobile phone to obtain various environmental data indicators in real time to eliminate various risks caused by environmental changes.
Application scenarios: parks, factories and other application fields
3. IoT Data Connection
The Bluetooth gateway can connect to terminal Bluetooth devices and can connect and control 20 Bluetooth terminal devices at the same time to realize two-way transmission between Bluetooth terminals and Bluetooth gateways. For example, the background sends data to terminal devices such as electronic price tags and electronic bracelets.
Application scenarios: supermarkets, hospitals, schools and other application fields.
