本文叙述了由TP801A单板机为核心可用于检测29点温度、3点湿度、2点风速的多点自动检测系统,及其在人防工程中的应用。为了提高检测的精度和自动化程度,在检测系统中设置了自动转换量程和采用了一种较简单的、但行之有效的数据处理措施。该检测系统经一年多昼夜不停地运行证明了其运行是可靠的,性能是良好的。 This paper describes a multi-point automatic detection system that can be used to detect 29 o’clock temperature, 3 o’clock humidity, 2 o’clock wind speed by the TP801A single-board machine and its application in civil air defense projects. In order to improve the detection accuracy and automation, the automatic conversion range is set in the detection system and a simple but effective data processing method is adopted. The system, which has been running around the clock for more than a year, has proved its operation is reliable and its performance is good.
