In order to improve the pavement evenness in the construction,based on CAN bus,this paper designed a digital auto-leveling control system.By the integrated use of CAN bus,DSP microprocessor,microcontroller and sensor technology,through reasonable structure design and a series of hardware and software design,the basic theory of feedback control system succeeded in applying to digital auto-leveling control system.The system has multiple types of sensors,can be applied to a variety of general construction machinery.The practice shows that,the digital sensors of the system detect road conditions accurately,helping construc-tion machinery working well.The system improves machine performance and construction quality,uses widely,saves resources and time.So,the system is a flexible and efficient auto-leveling control system.
