Automatic Horizontal Tank Capacity Test System Based On Polar Coordinate Measuring

This paper aims to study the automatic capacity verification system of horizontal tank which can automaticly measure, data process,thereby improving the efficiency and safety of horizontal tank capacity test. Select sufficient number of points in the vertical section. Using the laser range-based measuring equipment which can record rotated angle and tilt angle measure the distance from the center of the equipment to the selected point in certain path under the controller in the apparatus. The results stored in the storage card.Ccollected the data on gross error removed, coordinate transformation, least square fitting adjustment, data segmentation, cross-sectional area calculation, calculating the volume horizontal tank capacity.Select VisualBasic6.0 as application development platform, developed with data transfer, excluding outliers, data analyzing, result display software system. Horizontal Tank capacity automated test system have the function of data acquisition, data processing, result output.The system meets "horizontal tank volume of test procedures JG266-1996" standard,it is more safe, with high speed, high degree of automation. Finally, the result of the test were discussed.
