采用容错技术,通过2个MCU之间的CAN通讯的消息应答机制,设计了具有容错功能的六通道ABS系统。2个MCU同时接收和处理来自车轮传感器的轮速信号和故障诊断信号。如果主控MCU处于正常工作状态的时候,另一个MCU则处于备用状态,且实时地通过CAN总线和主控进行通讯,对其进行监控。如果主控MCU处于故障状态的时候,备用MCU立即接替主控MCU进行工作,以提高六通道ABS系统的可靠性。 相似文献

基于CAN总线的顶板离层计算机监控系统 总被引:2,自引:0,他引:2
国内顶板离层计算机测控系统多采用RS-485总线,传输效率低,可靠性不高.CAN总线控制器局域网是一种有效支持分布式控制或实时控制的串行通讯网络,和RS-485总线相比实时性、稳定性较好.文章运用CAN总线对顸板离层计算机监控系统进行设计.现场测试表明,其各项指标达到了设计要求,能够对顶板离层和可能的冒落进行实时预报. 相似文献

This paper describes a wheelchair for physically disabled people developed within the UMIDAM Project. A dependent-user recognition voice system and ultrasonic and infrared sensor systems has been integrated in this wheelchair. In this way we have obtained a wheelchair which can be driven with using voice commands and with the possibility of avoiding obstacles and downstairs or hole detection. The wheelchair has also been developed to allow autonomous driving (for example, following walls). The project, in which two prototypes have been produced, has been carried out totally in the Electronics Department of the University of Alcalá (Spain). It has been financed by the ONCE. Electronic system configuration, a sensor system, a mechanical model, control (low level control, control by voice commands), voice recognition and autonomous control are considered. The results of the experiments carried out on the two prototypes are also given. 相似文献
