摘要
室内环境温湿度是空调系统的两个主要参数,对其及时、准确测量是设计变风量空调风口形式的一个重要依据。介绍由单片机AT89C52和数字式、单总线型温度传感器DS18B20以及温湿度传感器SHT11组成的多点测量系统。采用28个DS18B20组成矩形测温网络,3个SHT11组成温湿度测量部分,有效地改善了系统的测控能力,为风口形式的设计提供了研究平台。
Temperature and humidity in indoor environment are two main parameters of an air-conditioning system, for which the accurate measurement is a basis of designing the type of the VAV air-conditioning vent. A multi-point measurement system composed of singal chip microcontroller AT89C52, single-bus category digital sensor DS18B20 and temperature / humidity sensor SHTI 1 is introduced. This system includes a rectangle temperature detecting network with 28 DS18B20 sensors and a temperature / humidity measurement section with 3 SHTll sensors, which efficiently improve the measurement and control ability of this system, and offer a research platform for designing the vents of VAV air-conditioning systems.
