摘要
从硬、软件设计方面,阐述所开发甲醛等有机挥发物释放量检测箱的控制系统特点。该系统由ATmega2560单片机构成控制器,完成检测室内温湿度的实时监控及自动控制,温度和湿度控制精度可分别达到±0.5%和±1%,相对可编程控制器的系统成本降低,且人机界面操作简便。
A control system,based on a microcontroller for a measuring instrument,was developed for formaldehyde and other volatile organic compound emissions.This article described the system hardware construction,software processing,and how to combine them in the system to realize real-time measuring and automatic controlling.The application of this system,for a 1-cubic formaldehyde measuring system,showed that the temperature and humidity control reached ±0.5% and ±1%,respectively.The cost for this micro-controlled instrument was reduced compared with that for a programmable logic controller.An intelligent man-machine interface,based on a touch screen,was also designed to make this an easily operated system.
