摘　　要：路面冷再生施工过程中,铣刨深度的控制精度直接影响到路面结构层的再生质量。现有的国产路面冷再生机铣深系统控制精度低、操作复杂且可靠性差。改进之前的铣刨深度控制系统,传感器为法兰固定式外置传感器,铣深控制算法较简单且精确度差,并未考虑基准零位偏差。通过对传感器的改型,铣深控制算法的改进,针对零位偏差提出支腿液压缸分段控制及车身倾斜控制等措施,将铣刨深度控制系统进行改进与提升。Precise control over pavement milling depth would direct affect formation quality of the rebuilt pavement surface,however,some defects have been found in the present home-made millers,including low precision control,complexity in operation plus poor reliability,which were resulted from flanged outfitted sensors,simpler algorithm in poor milling depth control without consideration for basic zero variation.The text provides measures to alter type of the sensor,improve the algorithm for milling depth control,sectioned outrigger cylinder control and car-body inclination control,etc in view of the zero variation existing,respectively,thus improving and upgrading the milling depth control system.
