| 摘 要： | 分析了目前常用的基于流量控制的沥青洒布控制系统的工作原理,针对其在洒布高粘度沥青材料时存在的喷洒压力不稳定、洒布不均匀和精度难以保证等问题,提出了基于压力控制实现沥青洒布的技术方案,并推导出了系统的控制方程,设计了相应的沥青管路系统,阐述了控制系统的硬件体系和软件设计要点。实践证明,基于压力控制理论设计的沥青洒布控制系统,具有洒布均匀度好、控制精度高等特点,尤其适用于高粘度沥青材料的洒布作业。

| Abstract: | Working principle of asphalt distribution control system based on flow control was analyzed.Due to the problems in distributing high viscosity asphalt that spraying pressure was unstable,spraying was uneven,and the accuracy was difficult to ensure,the distribution scheme based on pressure control was put forward.With the control equations being deduced,the asphalt pipeline system was designed,and the hardware framework and software design elements of control system were introduced.Practice showed that the a... |
