基于单片机的蓝牙搜救小车设计

Design of Bluetooth search and rescue vehicle based on single chip microcomputer

针对灾难现场救援设计了一款基于单片机的蓝牙搜救小车,借助手机平台与蓝牙技术,实现用手机蓝牙控制小车的新的解决方案。该设计以单片机为控制核心,通过串行口接收手机蓝牙发送给车载蓝牙的操作命令,控制电机正反转实现小车前进、后退、左转弯、右转弯、停止等操作。当小车上的红外传感器发现有生命特征的人时,把信息传送给单片机,单片机再通过语音模块把信息传送给外界,帮助救援人员快速找到受灾人员,及时赶到目的地进行搜救工作。小车上的避障传感器使该小车能够自动避障。

Aiming at the disaster site rescue designed a based on single -chip Bluetooth search and rescue car, with mobile phone platforms and Bluetooth technology, to achieve new solutions to control the car with a Bluetooth mobile phone. The design with MCU as the control core, through the serial port to receive Bluetooth mobile phone to send to a vehicle Bluetooth operation command, control the motor re- versing the car forward, backward, turn left, turn right, stop and other operations. When infrared sensor of the car found to have the characteristics of life, the information is transmitted to the MCU microcon- troller and through the voice module to message sent to the outside world and help rescue personnel quickly find the affected people, arrived in time to search rescue work. The obstacle avoidance sensor on the car to make the car can automatically avoid obstacles.
