准确，快速，方便地获得温度在现代企事业单位，厂房车间和家庭中有着越来越重要的意义。本文设计了一套基于MSC51单片机的温度采集系统。应用该系统可以即时、准确地获得两路温度参数（可扩展至256路），测温范围达0~125C，参数精确至0.25C，并可以现场控制欲采集的指定传感器的温度参数，通过数码管显示出来，通过RS232接口可连接至计算机，并通过监控软件观察实时数据和波形。该系统具有易扩展、精度高、成本低等特点，适宜现场监控，实验室，家庭等对温度有要求的场所。-Accurate, rapid and easy access to the temperature in the modern enterprises, plant has a home workshop and more and more important. This article has designed a single chip MSC51-based temperature acquisition system. Application of the system can be immediate, accurate access to two temperature parameters (can be expanded to 256 road), temperature range of 0 ~ 125C, precise parameters to 0.25C, and can be collected at the scene To control the temperature of the sensor parameters specified by the digital tube shown through RS232 interface can be connected to the computer and monitoring software through real-time data and waveform observation. The system is easy to expand with high precision, low cost, and suitable for field monitoring, laboratory, on the home
