在变电站蓄电池室内，环境的稳定对电池的性能和寿命至关重要。由于电池在运行过程中可能会产生有害气体，并且对温度和湿度的变化非常敏感，因此，传统的监测方法已无法满足现代变电站对安全和效率的要求。本文提出了一种基于STM32F103C8T6单片机的变电站蓄电池室内环境感知与反馈装置的设计方案。该装置集成了温湿度检测、PM2.5粉尘浓度检测、阈值设置、语音播报提醒、OLED显示以及WIFI远程数据传输等多种功能。通过实时监测蓄电池室内的温湿度和粉尘浓度，并与用户设定的阈值进行比较，装置能够及时发出语音提醒，并通过OLED显示屏直观展示环境参数和系统状态。此外，WIFI模块的集成使得用户能够远程接收数据并调整阈值，从而实现对变电站蓄电池室内环境的实时监控和智能管理。该装置的设计与实现，不仅提高了变电站蓄电池室的安全性，还提升了运维的便捷性和智能化水平。

Abstract
In the substation battery room, the stability of the environment is very important to the performance and life of the battery. Because the battery may produce harmful gases during operation and is very sensitive to changes in temperature and humidity, traditional monitoring methods can no longer meet the safety and efficiency requirements of modern substations. This paper presents a design scheme of substation battery indoor environment sensing and feedback device based on STM32F103C8T6 single chip computer. The device integrates temperature and humidity detection, PM2.5 dust concentration detection, threshold setting, voice broadcast reminder, OLED display and WIFI remote data transmission and other functions. By monitoring the temperature, humidity and dust concentration in the battery room in real time, and comparing it with the threshold set by the user, the device can send a voice reminder in time, and visually display the environmental parameters and system status through the OLED display. In addition, the integration of the WIFI module enables the user to receive data remotely and adjust the threshold, so as to achieve real-time monitoring and intelligent management of the indoor environment of the substation battery. The design and implementation of the device not only improve the safety of the substation battery room, but also enhance the convenience and intelligence level of operation and maintenance.
