采用APPLE微机进行数据采集和曲线图象处理,同时使用12位A/D接口卡,可使冷却曲线分辨率达0．1℃。支持软件用BASIC语言和机器语言编写,在判据使用方面,增加了一些主判据和辅助判据,删掉了多余数据,用逐步回归软件建立数学模型,一从而省掉了样杯中的碲涂料,测试精度又有提高,使灰铁成分和机械性能的同时检测成为可能。本系统还具有现场测试情况磁盘存档和调阅再现等功能。
Using APPLE microcomputer for data acquisition and curve image processing, while using the 12-bit A / D interface card, the cooling curve resolution of 0.1 ℃. Support software written in BASIC language and machine language, in the use of the criteria, the increase of some of the main criteria and supporting criteria, delete the redundant data, with the gradual regression software to establish a mathematical model, thus eliminating the need for a sample cup Tellurium coating, testing accuracy and improve the gray iron composition and mechanical properties of simultaneous testing possible. The system also has a field test disk archiving and retrieval and other functions.
