上海仪器仪表研究所最近研制成功以下仪器:(一)带微处理机的数控绘图仪,其技术指标为:①绘图有效幅面:900×1200毫米~2;②脉冲当量:0.05毫米/脉冲;③定位精度:0.1%;④重复精度;0.2毫米;⑤记录笔最高移动速度:36米/分。其性能稳定,机械传动结构简单,控制方便,移动速度和抬笔速度快,可见幅面大,绘图功能比较齐全,达到世界七十年代末产品的水平。(二)图形数字化仪,它能将图形资料转换成数字量,是实现
Shanghai Institute of Instrumentation recently developed the following instruments: (a) with a microprocessor-based plotter, the technical indicators: ① drawing effective format: 900 × 1200 mm ~ 2; ② pulse equivalent: 0.05 mm / pulse; ③ Positioning accuracy: 0.1%; ④ repeatability; 0.2 mm; ⑤ maximum recording pen speed: 36 m / min. Its performance is stable, mechanical transmission structure is simple, easy to control, moving speed and carrying speed fast, visible format, drawing more complete, reaching the world level of the late seventies products. (B) graphics digitizer, which can convert graphics data into digital, is to achieve
