基于uC/OS的嵌入式环境参数监测系统设计

基于uC/OS的嵌入式环境参数监测系统设计(论文11500字)
摘要：现阶段我国正处在经济的高速发展时期，传统能源的巨大消耗对环境造成了巨大的破坏，人们生活环境的空气质量直接影响到个人的身体健康。为了改善人们的生活质量，需要实时的监测家庭居住环境的有害气体。针对这一目的，本文设计了一种基于单片机的家居环境监测系统，它以STM32单片机为核心，分别用ZE08-CH2O甲醛传感器模组，DHT11数字型温湿度传感器模组，MQ2烟雾传感器模组采集甲醛气体浓度、温度、湿度、烟雾浓度，并用OLED屏实时显示这四个数据，可以设置烟雾浓度报警限值，当烟雾浓度到达报警值时，相应的蜂鸣器会报警，提醒人们解决问题。为了增强系统的可靠性并使程序调试变得简单，加入操作系统就成为必要，本文使用的是便于移植的μC/OS-II实时操作系统。

Design of Embedded Environment Parameter Monitoring System Based on uC/OS
Abstract:At this time, China is in a period of rapid economic development. The huge consumption of traditional energy has caused great damage to the environment. The air quality of people's living environment directly affects the health of individuals. In order to improve people's quality of life, it is necessary to monitor the harmful gases in the living environment of the home in real time. Aiming at this purpose, this paper designs a home environment monitoring system based on single-chip microcomputer. It uses STM32 single-chip microcomputer as the core, and uses ZE08-CH2O formaldehyde sensor module, DHT11 digital temperature and humidity sensor module and MQ2 smoke sensor module to collect. Formaldehyde gas concentration, temperature, humidity, smoke concentration, and use the OLED screen to display these four data in real time, you can set the smoke concentration alarm limit. When the smoke concentration reaches the alarm value, the corresponding buzzer will alarm to remind people to solve the problem.In order to enhance the reliability of the system and make the debugging of the program simple, it is necessary to join the operating system. This article uses the μC/OS-II real-time operating system.
