摘要
室内温度是空调系统舒适性的重要指标,对其及时、准确地测量显得非常重要。介绍单片机AT89C51和数字式、单总线型温度传感器DS18B20组成矩形测量网络采集空调室内40点温度,LabVIEW作为开发平台,二者之间通过串口实现数据通信,利用LabVIEW强大的数据处理和显示功能对采集的空调温度场数据进行实时处理、分析和显示,详细介绍了系统的硬件结构和软件模块的设计方案。
Temperature is a very important criterion of air- condition systemts comfort, so it is very significant to measure it accurately and real - timely. This paper introduces a data acquisition system of measuring 40 points temperature for air - condition room based on single wire digital sensor DS18B20 and microcontroller AT89C51 which are composed of rectangle measuring meshwork. The data communication between LabVIEW and microcontroller is executed via serial port,and the temperature field data of air- condition room are processed analyzed and displayed on LabVIEW. The hardware and software modules are also given in detail.
