【摘要】 车载记录仪经常在复杂的野外环境下进行数据存储,而且需要实时接收其他不同采集系统采集的数据,提出了一种车载数据记录仪的多通道CAN总线接口设计与实现方法。多通道CAN总线接口模块接收采集系统的数据后,控制记录仪工作。经过多次试验表明:记录仪能准确接收多通道数据,且无丢失无数据现象。进一步验证了车载记录仪的多通道CAN总线接口设计的合理性。更多还原

【Abstract】 On-board recorders,often in complex environments for data storage in the field and need to receive different collection systems in real time collection of data,this paper designs a multi-channel CAN bus interface for on-board data recorder design and implementation methods. Multi-channel CAN bus interface module receives data acquisition system,control recorders work. After several tests showed that multi-channel data logger correctly received,with no data loss. To further verify on-board recorders of multi channel CAN bus interface design is reasonable.更多还原
