摘要
随着电力行业的快速发展，电力工器具的安全存储与维护愈发重要。电力工器具长期处于温湿度异常的环境中，易出现绝缘老化、部件锈蚀等问题，不仅缩短使用寿命，还可能在作业时引发安全事故，威胁人员与设备安全。因此，研发一种能精准调控存储环境、实时监测温湿度的电力工器具安全柜十分必要。
本设计提出了一种基于 STM32F103C8T6 单片机的电力工器具安全柜。系统主要功能包括：通过 DHT11 温湿度传感器实时采集柜内环境温湿度数据；当温湿度超出设定上下限值时，系统自动控制对应继电器启动加热、制冷或除湿功能，维持柜内恒温除湿环境，同时触发声光报警模块提醒工作人员；用户可通过按键手动设置温湿度阈值、控制加热 / 制冷 / 除湿功能启停及切换工作模式；通过 OLED 显示屏实时显示当前温湿度、设定阈值及设备工作状态；此外，系统通过 ESP8266-12F WIFI 模块将温湿度数据上传至手机端，用户也可在手机端远程设置温湿度阈值、控制设备功能启停与模式切换。
该电力工器具安全柜为电力工器具的存储提供了稳定、可控的环境保障，通过自动调控与远程监控功能，减少人工干预成本，有效避免因环境因素导致的工器具损坏或安全隐患，保障电力工器具性能稳定，为电力作业安全提供有力支撑。

Design of Electronic Blood Pressure Monitor Based on Single Chip Microcomputer
Abstract
With the improvement of living standards and the enhancement of health awareness, monitoring blood pressure and heart rate has become an important part of people’s attention to their own health. For middle-aged and elderly people, abnormal fluctuations in blood pressure and heart rate, if not monitored and treated in a timely manner, may lead to serious health problems and even endanger their lives. Therefore, it is necessary to develop a device that can conveniently and accurately monitor blood pressure and heart rate.
This design proposes an electronic blood pressure monitor based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the current user’s diastolic and systolic blood pressure through the blood pressure detection module; Using a heart rate detection module to measure the current user’s heart rate; The user initiates the measurement by pressing a button; When abnormal heart rate or blood pressure is detected, the system will sound and light an alarm; Display measurement values through OLED; At the same time, the system stores the detected blood pressure through a storage module, which can hold up to 20 sets, and users can view them by pressing a button.
The function of this electronic blood pressure monitor is to provide people with a convenient and effective tool for monitoring blood pressure and heart rate. By timely monitoring and alerting, it can help people detect health hazards as early as possible, facilitate timely measures, ensure physical health, and improve quality of life.
