摘　　要：设计一种基于嵌入式微处理器的沥青砂浆车液压自动调平系统.其检测装置采用双轴水平传感器(角度传感器),控制器采用飞利浦的LPC2114微处理器,执行机构采用阀控液压缸.嵌入式微处理器LPC2114采用两点调平的算法,实现对沥青砂浆车的液压自动调平.实验结果表明:采用两点调平的方法,在调平精度为±0.2°的前提下,调平效率高、稳定性好.A hydraulic leveling system based on embedded microprocessor used in the asphalt mortar vehicle is developed.The measuring device of the system uses muti-axial level sensor（angle sensor）.Its controller uses Philips′s microprocessor LPC 2114 and its executive body uses valve-control hydraulic cylinder.A two-point leveling algorithm is used in the embedded microprocessor LPC 2114 to make the platform horizontal automatically.The results of experiments show that this leveling system is efficient and stable in leveling with leveling accuracy 0.2 degree.
