摘 要

随着人们生活水平的提高,住宅的安全性和智能性对现在的居民来讲是十分重要的。在住宅中,厨房为住宅中很重要的组成部分之一。厨房在住宅中的安全性广受关注,大部分的起火事故都是源于厨房,同时现在住宅中厨房都会通天然气,天然气泄漏会造成人员伤亡甚至爆炸事故。而在北方,人们使用空调、电暖气取暖,北方天气干燥,线路老化就会引起火灾。当发生火灾或者煤气泄漏时,家中独居的老人行动能力差,反应较慢,当危险发生的时候往往错过最佳的解决时机,因此在住宅中搭建一套智能的实时的同时性能良好的厨房综合检测系统是非常有必要的。

本文根据课题的需求,设计一款厨房老年人监控系统,系统可以对厨房环境中做饭的老年人进行生命监控,也可以对厨房中的环境因素进行采集,包括CO浓度等,同时加入了声光报警模块模块,在检测到危险时发出声光信号。系统设计分为硬件设计和软件设计,硬件设计包括单片机最小系统模块、气体检测模块、热释传感器模块、温度传感器以及周边电路模块组成;软件设计使用模块化的设计,包括主程序、延时程序以及报警程序等。

ABSTRACT

With the improvement of people's living standards, the safety and intelligence of residential buildings are very important for the residents. In residence, kitchen is one of the most important parts of residence. The safety of kitchens in residential buildings is widely concerned. Most of the fire accidents are caused by kitchens. At the same time, the kitchens in residential buildings are now supplied with natural gas, and the leakage of natural gas will cause casualties and even explosion accidents. In the north, people use air conditioning and electric heating for heating. In the north, the weather is dry, and the aging lines will cause fires. When there is a fire or gas leak, the elderly living alone at home have poor ability to act and slow reaction. When the danger occurs, they often miss the best time to solve it. Therefore, it is very necessary to build an intelligent real-time and good performance kitchen comprehensive detection system in the house.

According to the needs of the subject, this paper designs a monitoring system for the elderly in the kitchen. The system can monitor the life of the elderly cooking in the kitchen environment, and can also collect the environmental factors in the kitchen, including the concentration of Co. at the same time, it adds the sound and light alarm module to send out sound and light signals when danger is detected. The system design is divided into hardware design and software design. The hardware design includes the minimum system module of single chip microcomputer, gas detection module, heat release sensor module, temperature sensor and peripheral circuit module; Software design uses modular design, including main program, delay program and alarm program.

Keywords: Smart home; Safety monitoring; Gas sensor; Infrared sensor;
