Starting and barrier avoiding system of electrically powered wheelchair

Abstract

The invention discloses a starting and barrier avoiding system of an electrically powered wheelchair. The starting and barrier avoiding system comprises a master controller, a sensor module, a power management module and an auxiliary module. The sensor module comprises a position sensor. The power management module comprises a power source and a power source self-starting device, and the self-starting device serves as a power switch and is in a normally-open state to switch off power supply. When the self-starting device bears pressure, the switch is closed, and the power source is switched on. After the system is powered on, the position sensor sends sitting position information of a user of the electrically powered wheelchair to the master controller in real time, and the master controller judges whether the user is at the safe position or not according to the received position information. If the user is at the safe position, the master controller controls a power source control module to supply power to a driving device of the wheelchair. If it is judged that the user is not at the safe position, the master controller controls the power source control module not to supply power to the driving device of the wheelchair, and meanwhile the master controller controls a voice module in the auxiliary module to send a voice alarm signal that the user is not at the safe position. Through the starting and barrier avoiding system, the use safety and the convenient degree are improved for the user.

Description
