Design of Portable Intelligent Traffic Light Alarm System for the Blind

Abstract

AbstractThe system is composed of STC single chip microcomputer, color signal recognizer and sensor control module, wireless communication control module, voice and video synthesizer and broadcast control module. STC MCU adopts STC89C52; color recognition sensor module uses gy-33 color recognition sensor, which can identify the current traffic light conditions; wireless communication module uses nRF24L01 made by Nordic company, which needs to be installed at the sending end and the receiving end to send the current traffic light information; the speech synthesis broadcasting module uses the TTS speech synthesis broadcasting module xfs5152ce of iFLYTEK, after data recognition and analysis, it finally sends voice alarm about traffic lights to the blind, so as to effectively guide the blind whether it can pass through, so as to ensure the safety of the blind. This design combines artificial intelligence with daily life, which not only meets the development trend of the information age, but also meets the needs of the current society. It has a broad market prospect in the application of intelligent travel.
