摘　　要：传统的检测实验室环境温度监测常采用单一的电子式温度表或机械打点式温度记录仪,不具备实时自动监测功能且需耗费大量的专用纸张,既不经济也不环保。本文通过对新型数字温度传感器的应用,结合应用单片机、计算机、通信接口及数据库软件,设计了一套具备实时监测、报警及控制功能的实验室环境温度监测系统,该系统实现了一个系统多个场所的温度采集、监测,具备远程通信功能、数据库存储功能、温度实时曲线显示及打印功能等,系统的测量精度高、可靠性好,符合现代实验室对环境温度的监测使用要求。Normally the ambient temperature of traditional testing laboratory is measured by single electronic temperature meter or mechanical typing temperature recorder, which do not have real-time automatic monitoring function, and consume lots of specific paper, and that is not economically nor environmentally friendly. In this paper, by using new type of digital temperature sensor, combine with application of singlechip, computer, communication port and database software, a laboratory ambient temperature monitoring system with real-time monitoring, over temperature warming and controlling functions is designed. This system has functions of temperature collection of multiple sites, temperature monitoring, remote communication, database reservation, real time temperature curve displaying and printing, and it has high system accuracy and reliability. The system complies with requirements of ambient temperature monitoring of laboratory nowadays.
