【摘要】：随着国家节能降耗，走可持续发展之路政策的出台，道路施工中的沥青路面冷再生技术得到了广泛应用，冷再生机作为再生技术的核心施工设备，因其结构复杂、功能多、自动控制要求高，一直以来都被视为再生技术应用中的瓶颈，尤其是智能化控制方面还有待提高。这样就有必要对沥青路面冷再生机控制系统进行整体开发设计。本论文主要研究的是路面冷再生机自动控制系统。通过收集、比较、分析了国内外冷再生机的性能参数、技术特点等，，阐述了国内外冷再生机的发展状况，并给出了冷再生机的一般定义、组成结构和控制功能。通过分析冷再生机施工工艺过程，提出了控制系统功能需求和控制系统原理，根据功能要求及原理进行了冷再生机控制系统的总体方案设计、硬件配置、程序设计和应用实例分析。在冷再生机系统设计方面，完成了发动机控制系统方案、行走控制系统方案、转向控制系统方案、再生剂喷洒控制系统方案、冷却风扇控制系统方案和辅助装置控制系统方案。在硬件设计方面，给出了基于CAN总线通信技术的冷再生机全数字网络控制系统方案，完成了智能控制器、人机界面和坡度控制器的硬件设计，并对控制器进行了针脚分配。在软件设计方面，给出了冷再生机控制系统的主程序结构，设计完成了行走控制程序流程、喷洒控制程序流程、转向控制程序流程和通讯显示系统程序流程，并给出了相关流程图。在应用实例分析方面，介绍了ZBL2500型冷再生机的各项控制功能，通过城市道路改造和乡村道路改造的再生施工工业性考核试验过程分析，验证了控制系统的可行性。冷再生机控制系统的性能试验表明，冷再生机的各控制单元功能完备、控制简便、故障率低，达到了设计要求，可以进行批量生产。目前，该冷再生机控制系统已经应用在鼎盛天工工程机械有限公司的ZBL2500型冷再生机上，并已经量产。
[Abstract]:With the introduction of the national policy of energy saving and consumption reduction and sustainable development, the cold recycling technology of asphalt pavement in road construction has been widely used. As the core construction equipment of recycling technology, cold recycling machine has complex structure and many functions. Automatic control has been regarded as the bottleneck in the application of regenerative technology, especially in intelligent control. In this way, it is necessary to develop and design the control system of asphalt pavement cold recycling machine. This paper mainly studies the automatic control system of road surface cold regenerator. Through collecting, comparing and analyzing the performance parameters and technical characteristics of the cold regenerator at home and abroad, the development status of the cold regenerator at home and abroad is expounded, and the general definition, composition structure and control function of the cold regenerator are given. Through analyzing the construction process of cold regenerator, the function requirement and control system principle of control system are put forward. According to the function requirement and principle, the overall scheme design and hardware configuration of the control system of cold regenerator are carried out. Program design and application analysis. In the aspect of cold regenerator system design, the engine control system, the walking control system, the steering control system, the regenerator spraying control system, the cooling fan control system and the auxiliary device control system are completed. In the aspect of hardware design, the whole digital network control system scheme of cold regenerator based on CAN bus communication technology is presented. The hardware design of intelligent controller, man-machine interface and slope controller is completed, and the controller is allocated with pins. In the aspect of software design, the main program structure of the control system of cold regenerator is given. The flow of walking control program, spraying control program, steering control program and communication display system are designed and completed. The flow chart is given. The control functions of ZBL2500 type cold regeneration machine are introduced in the application case analysis. The feasibility of the control system is verified by the analysis of the industrial test process of urban road reconstruction and rural road reconstruction. The performance test of the control system of the cold regenerator shows that the control unit of the cold regenerator has complete function, simple control and low failure rate, which can meet the design requirements and can be produced in batches. At present, the control system of the cold regenerator has been applied to the ZBL2500 cold regenerator of Dingsheng Tiangong Construction Machinery Co., Ltd.
