【摘要】：力矩限制器是臂架类工程机械所必需的安全保护设备，公司目前生产的汽车起重机、履带起重机、轮胎吊、军港维修车、消防云梯等产品，必须安装安全保护装置。力矩限制器作为一种重要的起重机械超载保护装置，，就其技术而言，涉及以下几个领域：嵌入式硬件、嵌入式软件、结构计算、液压仿真、系统仿真、数值处理、EMC与可靠性设计等。本文通过对起重机力矩算法模型的研究，准确地建立了力矩限制器的算法模型，计算精度高、一致性好、适用性强、调试时间短；针对工程机械产品特有的恶劣环境，设计了稳定可靠的硬件系统，硬件系统具有专用的电源模块电路、故障自诊断功能、传感器自适应、电磁兼容抗干扰等功能；软件系统采用ARM+Linux+QT的嵌入式系统开发组合，在系统整体性能、界面效果、系统架构与程序清晰度方面都取得了良好的效果，裁剪Linux操作系统，优化底层驱动程序，有效提升软件运行的性能与可靠性；研制的力矩限制器进行相关国家标准的可靠性试验，符合相应的技术要求。本项目研制的力矩限制器，各项功能及技术指标即满足满足国家标准，同时远远优于公司原有的力矩限制器，达到了国际先进水平，力矩限制器具有较强的共性技术特征，并有非常广泛的应用领域，可以应用于其他工程机械产品。
[Abstract]:Torque limiter is the necessary safety protection equipment for bobbin type construction machinery. At present, the company produces truck cranes, crawler cranes, tire cranes, military port maintenance vehicles, fire ladders and other products. The torque limiter, as an important overload protection device of lifting machinery, is involved in the following fields: embedded hardware, embedded software, structure calculation, hydraulic simulation, system simulation, etc. Numerical treatment EMC and reliability design etc. In this paper, the algorithm model of torque limiter is established by studying the algorithm model of crane torque, which has the advantages of high accuracy, good consistency, strong applicability and short debugging time. A stable and reliable hardware system is designed. The hardware system has the functions of special power module circuit, fault self-diagnosis function, sensor adaptive, EMC anti-interference and so on. The software system adopts the embedded system development combination of ARM Linux QT. In the overall performance, interface effect, system architecture and program clarity, good results have been achieved. Cutting the Linux operating system, optimizing the underlying driver, effectively improve the performance and reliability of the software running; The torque limiter has been tested according to the relevant national standards. The torque limiter developed by this project meets the national standards for all functions and technical specifications, and is far superior to the original torque limiter of the company, reaching the international advanced level, and has strong common technical characteristics. And has a very wide range of applications, can be used in other construction machinery products.
