![]() ![]() ![]() The intelligent traffic light alarm system for the blind is designed to solve the problem of blind travel. Visual barriers seriously affect the blind people’s access to information and perception of the environment, making it impossible for them to travel normally, even in places they often visit and familiar environment, There are also all kinds of stumbling, let alone never set foot in the place, so if you want to go to a completely strange, never crossed street, but because you can’t get real-time road conditions, then their travel safety is difficult to achieve even the lowest guarantee, it’s just like this, many blind people don’t want to go out of the house, so they have no way to better integrate into the society and achieve their goals The value of life, which is a pity for the blind, is the loss of national and social resources, so it is urgent to effectively help the blind travel safely and normally. Nowadays, the number of blind people in China is the largest in the world, with more than 6 million blind people. It has a broad market prospect in the application of intelligent travel. 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. ![]() 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. The 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. ![]()
