Intelligent Control System of Textile Mill＇s Air-conditioning

This paper briefly analyzes the present situation of textile mill's air-conditioning system. Since it is difficult to establish detailed math model to control a textile mill's air-conditioning system because of the influence of various factors such as the differences in seasons,regions,etc.,most air-conditioning equipment can not be controlled automatically. This paper suggests utilizing multi-function data acquisition card to collect the data about the temperature and humidity of a workshop,processing the ...     

多功能土工材料力学性能计算机分析测试系统

为了提高土工材料力学性能分析的精度与效率，本文提出了一种新的分析测试方法。即利用计算机内插驱动卡驱动步进电机，步进电机拖动实验台进行试验，数据采集卡采集位移与拉、压力的数据，经A／D转换输入计算机，再经计算机对数据进行处理，结果由打印机打印。其中数据的采集采用动态数据库链接。实际测试结果表明精度完全满足国标GB／T17633和用户的要求。
