采用低功耗89C55型CPU与少量外围芯片、宽温型背光点阵式液晶显示器、高精度传感器构成智能铁道测试仪. 其操作方式由液晶汉字提示,测量数据由仪器自动检测纪录,故障自动提示并声音报警. 作为铁轨直线段和小曲率半径线段的综合测量仪器,可测量两条轨道的内侧宽度、两条轨道的高度差和测量记录点的定点距离. 经过大量现场测量试验,其全部性能基本达到设计指标要求.
Using low-power 89C55-type CPU and a small amount of peripheral chips, wide-temperature backlight dot-matrix LCD, high-precision sensors constitute intelligent railway tester. The mode of operation by LCD Chinese tips, measurement data automatically detected by the instrument records, automatic fault tips And sound alarm.As a comprehensive measurement instrument of linear section and small radius of curvature section, it can measure the width of the inside of the two tracks, the height difference between the two tracks and the fixed point distance of the measured recording point.After a large number of field measurement tests, the overall performance Basically meet the design requirements.
