In order to enable people with disabilities to fully enjoy the convenience brought by modern technology and experience the comfortable life assistance brought by the intelligent Internet of Things, our team has accumulated many years in related fields and established and improved the brain-computer Internet of Things platform based on AI and VR with brain-computer interface as the terminal input device. The brain-computer IoT platform architecture is divided into three major modules: self-research EEG acquisition equipment, cloud analysis platform and IoT system. Through the three key technologies of brain-computer interface, VR and artificial intelligence, the four major areas of smart pension, smart entertainment, smart medical care and smart education are empowered. The core processor of this work is Xilinx series FPGA chip, using VHDL language, the pre-filter logic circuit and the back-end vpu processor are concentrated on one chip, realizing the integration and miniaturization of EEG amplification, filtering, processing and output. In terms of circuit design, the team designed a set of Bluetooth and WiFi integrated communication module based on esp32 and stm32f103c8t6 chips based on Altium designer, realizing a wide and flexible communication interface for external devices. (1)BIoT smart pension In the field of intelligent old-age care, our team has built a brain-controlled wheelchair device to assist patients with lower limb disabilities in their lives, and has set up a safety classification model for equipment based on artificial intelligence. The relevant soft works and patents have been granted. The wheelchair device studied by the team provides a new way of external communication for patients with limb dysfunction. It does not rely on peripheral nerve tissue and muscles, so that the brain can directly control external devices. Universities, research institutes and other scientific research institutions to cooperate in research and development, nursing homes, hospitals and other social organizations to promote cooperation. (2)BIoT Smart Entertainment In the field of smart entertainment, our team has built a new generation of immersive entertainment system with VR brain-computer interface. Operators can play archery games in VR space through their minds. Relevant soft works have been authorized and relevant patents are being accepted. (3)BIoT Smart Healthcare Our team cooperated with Beijing Xuanwu Hospital to apply the brain-computer intelligent device developed by our team to the clinical rehabilitation training of patients with Alzheimer's disease. After a certain period of training, the patient's spatial memory ability and spatial navigation ability have been significantly improved, and related papers will be published in international authoritative journals soon. (4)BIoT wisdom education In the field of wisdom education, my team has developed a set of mind shooting games to train children's concentration and improve their learning efficiency. The device can emit a laser while the user is focused, and the laser target will appear in a yellow-green blinking state.
