摘 要
随着我国经济迅速发展，城市化的进程越来越快，大量的高层建筑拔地而起，大型商场、物流仓库、易燃物品的存储仓库等场所的规模也在不断扩大，导致近年来火灾频繁发生。这些可能发生火灾的场所通常伴随着巨大的危险，消防人员不易进入，灭火救援行动难以及时开展，因而由火灾导致的财产损失和人员伤亡通常非常严重，研究智能灭火机器人刻不容缓。本设计中的智能灭火机器人使用了高性能、低功耗、接口丰富的STM32作为控制芯片，便于实现智能灭火机器人功能的拓展。
本设计中的智能灭火机器人采用了双轮平衡小车的设计，相对于四轮机器人具有更高的灵活性和火场机动能力，适合在复杂条件下快速找到火源进行灭火。
本文首先介绍了智能灭火机器人的主控制器、传感器以及电机的选型；之后根据所选择的器件搭建了硬件系统，设计了相应的控制电路、电机驱动电路和电源电路；然后在软件设计方面，机器人姿态控制算法通过JY-901姿态传感器快速获取机器人当前姿态信息，并传递给控制器，进而控制电机的转速和正反转来保证机器人能够平衡直立行走，并且结合光电传感器、火焰传感器等传感器设计了灭火机器人转向的算法，实现灭火机器人在复杂环境中自主循迹避障和寻找火源的功能。

Abstract
With the rapid development of China's economy, the process of urbanization is getting faster and faster, and a large number of high-rise buildings are emerging. The scale of large-scale shopping malls, logistics warehouses, storage warehouses for flammable materials, etc. is also expanding, leading to fires in recent years. It happens frequently. These places where fires may occur are often accompanied by huge dangers. Firefighters are not easy to enter, and firefighting and rescue operations are difficult to carry out in time. Therefore, property damage and casualties caused by fires are usually very serious. It is urgent to study intelligent fire extinguishing robots. The intelligent fire extinguishing robot in this design uses the STM32 with high performance, low power consumption and rich interface as the control chip, which is convenient for the expansion of the function of the intelligent fire extinguishing robot.
The intelligent fire-extinguishing robot in this design adopts the design of the two-wheel balance trolley. Compared with the four-wheeled robot, it has higher flexibility and fire field maneuverability. It is suitable for quickly finding fire sources to extinguish fire under complicated conditions.
This paper first introduces the selection of the main controller, sensor and motor of the intelligent fire extinguishing robot; then builds the hardware system according to the selected device, designs the corresponding control circuit, motor drive circuit and power supply circuit; then in software design, The robot attitude control algorithm quickly acquires the current attitude information of the robot through the JY-901 attitude sensor and transmits it to the controller, which in turn controls the rotation speed and forward and reverse of the motor to ensure that the robot can balance the vertical walking, and is designed with sensors such as photoelectric sensors and flame sensors. The algorithm of the fire-fighting robot steering realizes the function of the fire-fighting robot to autonomously follow obstacles and find the fire source in a complex environment.
