摘　　要：在数字化和智能化的背景下,智能压实技术逐渐成为机场、道路、港口等领域填土压实的主流趋势。然而,当前的冲击碾压施工工艺仍然采用人为确定路径的方式对路径进行规划与控制,严重影响了压实效率和压实质量。为了解决该问题,提出了一种冲击压路机路径优化与控制方法。首先,详细描述了冲击压路机的压实过程,揭示了冲击压路机路径规划问题的本质。将压路机路径规划问题等效为经典的旅行商问题,建立了以最短转弯距离为目标的数学模型,同时设计了相应的路径优化模型求解器,以实现对压实路径的自主优化。其次,结合数据库、GMap.NET二次开发及物联网等技术,研发了基于.NET框架的路径导航平台,用于实时控制压实路径。最后,通过算例和现场测试对所提方法进行验证。结果表明:所提方法能够根据工作面情况以及压路机基本参数确定最佳压实路径,相较于传统的路径规划方法,该方法能够缩短压实路径,提高压实效率。同时,研发的路径导航系统能够在压实过程中稳定地提供可视化路径,实现路径的实时控制,从而有效保障压实质量。With improving digitalization and intelligence,intelligent compaction technology has become the future development trend for filling compactions in areas such as airports,roads,and ports.However,the current impact-rolling construction process still requires a human to plan and control the path,which seriously affects the compaction efficiency and quality.To address this problem,an impact-roller compaction-path optimization and control method is proposed.First,the impact-roller compaction process was described in detail,and the essence of the impact-roller path-planning problem was revealed.Next,the impact-roller path-planning problem was regarded as a classic traveling salesman problem.A mathematical model was established,with the shortest turning distance as the target,and the corresponding model solver was designed to autonomously optimize the compaction path.Second,combining technologies such as databases,GMap.NET's second development,and the Internet of Things,a path-navigation platform based on the.NET framework was developed to control the compaction path in real time.Finally,the proposed method was verified using an example simulation and field test.The results show that the proposed method can obtain the optimal compaction path,based on the working-surface condition and basic parameters of the impact roller.Moreover,it can reduce the compaction path and improve the compaction efficiency compared with the traditional path-planning method.In addition,the developed path-navigation system can stably visualize the compaction path during compaction and control the path in real time,thereby guaranteeing the compaction quality.
