| 中文摘要: |
| 矿用电动轮自卸车由于其趋向大型自动化、结构复杂化,使设备故障维护难度加大,因此文中根据实际需求设计了在线状态监测和故障诊断系统.在该系统中,为了提高数据合理有效的采集与传输,采用了CAN网络总线结构,同时系统使用了高性能的数字信号处理器TMS320F2812作为信息单元、状态监测器的微控制芯片,并在状态监测控制器上采用了实时多任务嵌入式操作系统DSP/BIOS,满足了诊断系统并发多任务的需要,上位机设计了基于故障诊断专家的管理系统.实验表明,系统基本满足设计要求. |
| 英文摘要: |
| Due to its tendency of large automation and complicated structure, mine explosion-proof electric wheel dump truck makes the equipment fault maintenance harder; therefore according to the actual requirements, the online condition monitoring and fault diagnosis system is designed in this paper. In the system, in order to improve the reasonable and effective data collection and transmission, the system adopts CAN bus network architecture, and meanwhile the system uses the high performance digital signal processor TMS320F2812 as the controller of information unit and the state monitoring. The streamlined real-time multitasking embedded operating system DSP/BIOS is adopted on the condition monitoring controller, which will meet the needs of concurrent multitasking. The management system based on fault diagnosis expert is designed on the upper machine. Experiment shows that the system can meet the design requirements. |
