一种基于STM32野外应急系统的研究
An STM32-Based Field Emergency Response System

本文旨在解决牧民在放牧过程中面临的风险和挑战，通过引入一款创新的野兽驱赶装置，为牧民的人身安全和财产安全提供更强有力的保障。本文首先阐述了项目的背景与意义，强调了保护牧民和降低野兽威胁的紧迫性。随后，详细介绍了野兽驱赶装置的设计原理和技术实现。该装置利用单片机控制步进电机，精确控制气瓶向气球充气，使气球快速膨胀并释放内置的辣椒素。同时，装置还能发出特定频率的噪声和高频闪光，进一步增加驱赶野兽的效果。本文还讨论了该装置在未来多种应用场景中的潜在作用，特别是在野生动物可能对人类居住区、农田或其他财产构成威胁的地区。通过本文的研究，我们期望为牧民提供更安全的放牧环境，并为野生动物管理提供新的技术手段。
The aim of this paper is to address the risks and challenges faced by herders during the herding process by introducing an innovative wild beast repellent device that provides stronger protection for herders’ personal safety and property security. The paper begins by describing the background and significance of the project, emphasising the urgency of protecting herders and reducing the threat of wild animals. Subsequently, the design principle and technical realisation of the wild beast repelling device are described in detail. The device uses a microcontroller to control a stepper motor and precisely control the inflation of a gas cylinder into a balloon, causing the balloon to rapidly expand and release the built-in capsaicin. At the same time, the device also emits noise of a specific frequency and a high-frequency flash to further increase the effect of repelling wild animals. This paper also discusses the potential usefulness of the device in a variety of future application scenarios, especially in areas where wild animals may pose a threat to human settlements, farmland, or other property. With this paper, we expect to provide safer grazing environments for herders and new technological tools for wildlife management.
