基于CAN总线的汽车起重机智能控制系统

阐述了大型汽车起重机的发展趋势，指出了开发基于CAN总线的大型起重机智能控制系统具有重大意义。介绍了系统主要控制对象，提出了一套完备的自适应的智能控制系统。针对CAN总线技术应用中普遍存在的问题：由于单条总线太长引起的系统不稳定和总线容易冲突，提出了一种改良的CAN网络拓扑结构，其采用总线分段，双CAN总线协议结构。通过该汽车起重机在现场试运行时表现的卓越品质，验证了此智能控制系统的优越性。

CAN based truck crane intelligent control system

Development trends of large truck cranes are expounded, indicating that developing of CAN based large crane intelligent control system is of great significance. Considering the main control objects, a complete self - adaptive control system is developed. Such problems as system instability due to a too long bus system and bus conflict often occurs in application of CAN technology. An improved CAN topology structure is introduced, which features sectioned bus system and dual - CAN - protocol. Trial run of the truck crane with the intelligent control system shows that the intelligent system is of excellent performance.
