Embodiment 1
[0037] Using i.mx6 core board, EEG signal acquisition and processing through SPI bus, the EEG signal obtained by ADS1299 can be obtained through CCA. "EEG signal. Flashing and displaying on the main display through hdmi the flashing blocks in the "self-control" mode, obstacle prompts and dual camera images; the 104 keyboard in the "assist" mode is used to type notices to the network server; the user's destination or intention , obstacle prompts and dual camera images. Wheelchair and pan / tilt control, control the two motors of the electric wheelchair and the pan / tilt to move through the PWM signal. In order to ensure comfort, the movement speed in the "self-control" mode shall not exceed 0.5 m / s. No more than 10 km / h (2.78 m / s) in "assist" mode. The network connection is connected to the Bluetooth wifi two-in-one module RL-UM02WBS-8723BU through the USB interface to realize the connection with 4G. Image transmission transmits the dual camera images to the web server. For n...
