北京大学四号风洞是1958年建成的一座老风洞,测量控制设备陈旧落后,已不能适应空气动力学实验发展的需要。从1982年9月起,到1984年3月,用一年半的时间完成了以PC-8000微型计算机为中心的测控系统的调试。经过试运转,证明该系统数据采集精度高。基本达到准实时处理;系统稳定性强,软件丰富灵活,满足实验过程控制和数据处理的要求。近一年的使用情况证明该系统是成功的,它使北京大学四号风洞实验自动化迈出了第一步。
The No. 4 wind tunnel at Peking University was built in 1958 as an old wind tunnel. Measuring and controlling equipment is outdated and can no longer meet the needs of the development of aerodynamics experiments. From September 1982 to March 1984, commissioning of a PC-8000 microcomputer-centric measurement and control system was completed in a year and a half. After commissioning, that the system data acquisition accuracy. Basic to achieve real-time processing; system stability, rich and flexible software to meet the experimental process control and data processing requirements. The use of the past year proves that the system was successful and it took the first step towards experimental automation of the wind tunnel in Peking University.
