Abstract
With the continuous development of science and technology, artificial intelligence technology has gained a good opportunity. It has brought many conveniences to human production and life, and solved many problems that could not be solved before. How to apply electronic information technology has become the focus of attention. It can quickly solve different difficult problems in each link, improve work efficiency and design accuracy. And in the design process to improve and improve the actual design requirements at the same time to ensure the quality level. This paper designs a mobile phone anti loss device, which is mainly composed of STC89C52 minimum single chip system, Bluetooth module, power supply and anti-loss device. The anti-loss system of mobile phone needs a smart phone supporting Bluetooth to connect with the Bluetooth main board. The data between the single chip computer and Bluetooth is transmitted to the anti-loss device of mobile phone through the serial port. When the Bluetooth of the mobile phone is successfully connected to the Bluetooth motherboard, the anti-loss device shows that it is connected. When the distance between the mobile phone and the Bluetooth main board exceeds the safe distance, disconnect the connection and alarm the mobile phone and the Bluetooth main board at the same time.
