【摘要】：加载系统是在实验室条件下模拟伺服系统实际运行过程中所受真实载荷的试验装置。伺服系统为了保证其性能,在交付之前不仅需要空载试验还需进行多次的加载测试试验。传统的加载系统可加载测试对象单一,体积较大,使用范围较窄。所以研制一种新型的便携式伺服加载装置以适用于多种不同类型的伺服系统,有着重要意义和较好的市场前景。本文在总结传统加载测试系统特点的基础上,结合常用伺服系统的负载特性,设计了一种新型的便携式加载测试仪。该加载测试仪主要由加载控制器、加载电机、电机驱动器等部分组成,其中加载控制器是整个装置的核心控制单元,具有通用性强、便携性高等特点。加载控制器设计了如下功能包括对双轴伺服系统的多种典型负载波形的实时加载以及对伺服系统速度信号的采集与分析。加载控制器的硬件设计采用S3C2410A作为核心处理器,人机交互界面采用Linux内核和10.2寸的触摸屏代替传统的工控机来提高系统的便携性。在软件方面,对嵌入式Linux系统进行了裁剪和移植,并在此基础上设计了A/D输入、D/A输出的驱动接口程序,最后完成了人机交互界面的程序设计。整个加载控制器软硬件集成于一体,去除了传统加载控制器的PCI/ISA板卡,降低了控制器开发难度,减少了装置体积,提高了便携性。目前,本设计已完成加载测试仪的总体设计、整体的硬件设计、驱动软件的设计和应用软件的设计,并在此基础上完成了整体装置的调试。
[Abstract]:The loading system is an experimental device to simulate the real load of the servo system during its actual operation under the laboratory conditions. The servo system is designed to ensure its performance. Before delivery, not only the no-load test but also many loading tests are needed. The traditional loading system can load the test object single and the volume is large. Therefore, the development of a new type of portable servo loading device suitable for many different types of servo systems has important significance and good market prospect. On the basis of summarizing the characteristics of the traditional loading and testing system and combining the load characteristics of the common servo system, a new type of portable load tester is designed, which is mainly composed of a load controller. The load controller is the core control unit of the whole device, and has strong versatility. The load controller has the following functions, including the real-time loading of several typical load waveforms of the two-axis servo system and the acquisition and analysis of the speed signal of the servo system. Hardware design of the loading controller. S3C2410A is used as the core processor. The man-machine interface uses the Linux kernel and the 10.2-inch touch screen instead of the traditional industrial control computer to improve the portability of the system. In the software aspect, the embedded Linux system is cut and transplanted. On this basis, the driver interface program of A / D input / D / A output is designed. Finally, the program design of man-machine interface is completed. The whole loading controller software and hardware are integrated into one. The PCI/ISA card of the traditional loading controller is removed, the difficulty of developing the controller is reduced, the device volume is reduced, and the portability is improved. At present, this design has completed the overall design of the loading tester, the overall hardware design, the design of the driving software and the design of the application software. On this basis, the debugging of the whole device has been completed.
