Applying Internet of Things to Data Monitoring of Powered Wheelchairs

Abstract

The aim of this study is to use the Internet of Things (IoT) for data monitoring of powered wheelchairs, which is divided into monitoring the position, tire wear, and battery charge level. Our system can be divided into two parts: Arduino UNO (an open-source microcontroller board; the word "uno" means "one" in Italian) and Raspberry Pi. Arduino UNO combines radio frequency identification (RFID) to read Electronic Product Code (EPC) tag information to establish the position information of powered wheelchairs. Raspberry Pi, through cooperation with the Quantum Geographic Information System (QGIS), establishes a coordinate activity map and monitors the tire wear of the powered wheelchair at any time, and uses a DC100 V LED dual display digital voltage meter head and external shunt to detect the lead-acid battery charge level of the powered wheelchair. Finally, a Microsoft Excel macro and Excel Visual Basic for Applications (VBA) are used to integrate the EPC tag information, tire wear, and lead-acid battery power consumption data and display them as real-time dynamic charts. The user can know the status of the wheelchair at any time, the user's family can also know the operation status of an elderly user or one with limited mobility, and the user is informed in advance when the wheelchair needs to be adjusted.

Research on Intelligent Wheelchair Multimode Human–Computer Interaction and Assisted Driving Technology

“…Welihinda et al proposed a hybrid control system to operate a powered wheelchair using a combination of EEG and EMG, and developed an EEG-based user attention detection system and an EMG-based navigation system [20]. Regarding human-computer interaction between the guardian and the wheelchair, Lu et al used Internet of Things (IoT) technology to monitor the data of the position of the electric wheelchair, the tire wear, the battery power level, etc., and the guardian can know the user's operation status [21]. Li et al designed a mobile terminal APP based on virtual reality and IoT technology, sent commands to a remote server through the app, and completed rehabilitation training with the help of virtual reality technology [22].…”
