Title:
INDOOR AIR CIRCULATION SYSTEM BASED ON BLOCKCHAIN TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2020/151076
Kind Code:
A1
Abstract:
An indoor air circulation system based on blockchain technology, comprising a detection unit, an NBIoT communication device, a cloud server, a single-chip microcomputer (7), a window, and an air circulation electric fan (3). The window comprises a shutter (4) and a driving device (5) for driving the shutter (4) to be opened/closed. The air circulation electric fan (3) is arranged indoors. The detection unit uploads detection data to the single-chip microcomputer (7). The single-chip microcomputer (7) stores the data and uploads the detection data to the cloud server by means of the NBIoT communication device. The detection unit comprises temperature and humidity sensors (6, 9), a door magnetic sensor (2), and a wind speed sensor (8). The door magnetic sensor (2) is mounted on a door frame, and the wind speed sensor (8) is arranged outdoors. A user edits the gear of the air circulation electric fan (3) and the opening/closing state of the shutter (4) into a command having an eight-bit data length and sends the command to the cloud server by means of a mobile communication device. The cloud server receives the command, broadcasts the command to other cloud server nodes, and then sends the command to the single-chip microcomputer (7) specified by the user to control the gear of the air circulation electric fan (3) and the opening/closing state of the shutter (4).
