A Control System of Electric Wheelchair

Abstract

This paper designs a control system for electric wheelchairs for electric wheelchairs, including: main controller, sensor module, power management module and auxiliary module, sensor module includes position sensor; power management module includes power supply and power self-starting device, The starting device acts as a power switch and is in a normally open state to disconnect the power supply. When the self-starting device is under pressure, the switch is closed and the power is turned on; after the system is powered on, the position sensor takes the seat position information of the electric wheelchair user in real time. Sending to the main controller, the main controller determines whether the user is in a safe position according to the received position information. If in the safe position, the main controller controls the power control module to supply power to the driving device of the wheelchair; if it is determined that the user is not in a safe position Then, the main controller controls the power control module to not supply power to the driving device of the wheelchair, and the main controller controls the voice module in the auxiliary module to issue a voice alarm signal that is not in a safe position. Through the system designed in this paper, the user’s safety and convenience are improved.
