TH13633C3 - Blind barrier detector - Google Patents

Abstract

An obstacle-detecting device for the blind according to this invention. It consists of two main parts: the wooden part and the processing part. The carrying part and the processing section are connected by wires, with the carrying part there Below is a handle that fits your hand. The top has a component that is a wide barrier recognition device. It relies on the function of a laser scanner sensor that can provide information on the distance of the incident at various angles around it. The sensors work in conjunction with programming to analyze what is obstructions and send an alarm to the audio receiver via Bluetooth. By sounding the alarm in the form of sound frequencies according to distance Of the barrier The closer the frequency, the higher the sound.
