An Improved Smart Helmet for Safe Travel of Deaf People Based on Embedded System

An improved smart helmet for deaf people to travel safely based on embedded system is proposed in this paper. The helmet designed in this paper includes solar charging, distress confirmation, steering detection, horn prompt and other functions. The distress confirmation function will give an audible and visual alarm when the head of rider is hit strongly and send positioning and rescue information to the set emergency contact. At the same time, the steering detection function will detect the head posture and prompt the passers-by behind through LED. In addition, the horn prompt function will collect and filter the surrounding sound information, and when a car whistles, the rider is prompted by the vibration motor inside the helmet vehicle location information enables it to avoid in time. Experiments show that the helmet we designed can better meet the needs of deaf people and fully protect the safety of deaf riders.
