摘要: 生存环境的舒适与安全是人类永恒追求的物质目标。随着计算机技术、通信技术、控制技术的飞速发展,人们对居住环境提出了更高的要求,希望居住在一个生活现代化,环境舒适化、安全化的生活空间。通过环境监测系统,用户可以实时获得居住环境的信息,如:温湿度、天然气浓度、火灾信息等。并将采集到的环境信息作为其他家庭设备运行时的参数,实现对环境的智能化控制。智能无线天然气烟雾监控终端作为智能家居的一部分,很好地实现了实时监测天然气浓度和烟雾浓度的目标,并且当浓度超过设定阈值时,将通过无线的方式进行报警。
智能终端通过各种传感电路检测室内的天然气浓度和烟雾浓度信息等,然后与预置的参数阈值进行比较,智能终端根据比较结果发出相应的报警信息,并且可以实时地显示当前时间室内天然气浓度和烟雾浓度信息等参数值,并且可通过WIFI,GPRS等无线通讯方式及时将各种监控信息通知住户。
本文将从ST公司的以Cortex-M3为内核的STM32微处理器STM32F107和嵌入式图形支持系统UCGUI为主要切入点,对智能无线天然气烟雾监控终端所采用的技术进行数据分析、比较、甄别、判断,来证明它在日常生活中的实用性和优越性。

Design of data display system of intelligent gas monitoring terminal
Abstract: Living environment is the human eternal pursuit of material comfort and security goals. Along with the computer technology, communication technology, control technology rapid development, the living environment of people put forward higher request, want to live life in a modern, comfortable, safe environment of living space. And will be collected environmental information as other family equipment run time parameter, the realization of intelligent control to the environment. Intelligent wireless gas smoke monitoring terminal as part of the smart home, well realize the goal of real-time monitoring of gas concentration and smoke concentration, and when the concentration is more than set threshold, willthrough the wireless way to call the police.
Intelligent terminals through a variety of sensing circuit testing indoor gas concentration and smoke concentration information, etc., and then compared with the parameters of preset threshold, intelligent terminal sends the corresponding alarm information, according to the results of the comparison and can real-time display the current time indoor parameters such as gas concentration and smoke concentration information value, and can be through WIFI, GPRS wireless communication mode shall notify residents of various monitoring information in a timely manner.
This article will from the ST's architecture (M3 as the kernel of STM32 UCGUI STM32F107 microprocessor and embedded graphics support system as the main entry point, for the smart wireless gas smoke control technology adopted by the terminal for data analysis, comparison, identify, judgment, practicality and superiority to prove it in daily life.
