The CAN bus short frame structure may result in the transmission failure of the large size data, while the frame number and bitmap technique can effectively solve the problem. 基于帧号和位图进行数据包的拆分与重组,解决了由于CAN总线本身的短帧结构所造成的大数据量传输困难的问题。
The simple structure, flexible communication manner, special short frame format and effective bus arbitration technology make CAN bus a new way for highly reliable data transfer in industrial control and measurement system. CAN总线以其简单的结构、灵活的通信方式、独特的短帧格式、高效的总线仲裁技术,为工业测控系统中高可靠性的数据传送提供了一种新的解决方案。
