本论文介绍了一种名为”蓝牙语音寻物器”的智能设备，基于单片机STC89C52进行控制与通信。该寻物器具备蓝牙连接、按键控制和语音识别等功能，旨在帮助用户迅速找回遗失的物品。首先，通过蓝牙连接主从机，当主从机配对成功后，两者的蜂鸣器都响一下，主从机的LED灯则一直闪烁，以提示用户配对成功。通过蓝牙通信，主从机之间建立了可靠的连接，为后续功能提供了基础。其次，在主机中，设有一个独立的按键，用户可通过按下该按键来寻找从机。一旦按键被按下，主机向从机发送指令，从机接收到指令后，蜂鸣器响起持续5秒钟。这样，用户可以通过按键操作快速定位遗失的物品所在位置。另外，在主机中加入了语音识别模块，用户可以通过语音指令来寻找从机。主机通过语音识别模块识别用户的指令，然后将指令传输给从机，从机接收到指令后，蜂鸣器同样响起持续5秒钟。这一功能通过语音交互为用户提供了更加便捷的操作体验，使寻物过程更加智能化。通过上述功能的实现，蓝牙语音寻物器提供了一种高效、智能的方式来帮助用户找回遗失的物品。该设备结合了蓝牙连接、按键控制和语音识别等技术，为用户提供了便捷、准确的寻物体验。

This paper presents a smart device called “Bluetooth Voice Locator” that is controlled and communicated using the STC89C52 microcontroller. The locator is equipped with Bluetooth connectivity, button control, and voice recognition capabilities, aiming to assist users in quickly locating their lost items. Initially, the master and slave devices establish a reliable connection through Bluetooth pairing, indicated by a simultaneous beep from their respective buzzers and continuous LED blinking on both devices. This Bluetooth communication sets the foundation for subsequent functionalities.Within the master device, there is a dedicated button that allows users to initiate the search for the slave device. Upon pressing the button, the master device sends a command to the slave device, triggering the slave device’s buzzer to sound for 5 seconds. This enables users to quickly determine the location of their lost item through a simple button operation. Additionally, a voice recognition module is integrated into the master device, enabling users to find the slave device using voice commands. The master device recognizes the user’s voice command through the voice recognition module and transmits the command to the slave device, resulting in the slave device’s buzzer sounding for 5 seconds. This feature provides users with a more convenient and interactive experience, making the item search process more intelligent.By implementing the aforementioned functionalities, the Bluetooth Voice Locator offers an efficient and intelligent solution for locating lost items. The device combines Bluetooth connectivity, button control, and voice recognition technologies, providing users with a convenient and accurate item search experience.
Keywords: Bluetooth connectivity, voice recognition, STC89C52 microcontroller, locator, button control, lost item localization..
