本文構(gòu)建了一種基于CAN 總線技術(shù)的電子產(chǎn)品批量自動測試平臺，通過該平臺可以利用總線技術(shù)自動完成電子產(chǎn)品的檢測。其核心是在CAN 總線之上附加一種自動節(jié)點探測算法，這種探測算法將CAN 總線節(jié)點分為主節(jié)點和從節(jié)點，主節(jié)點將自動檢測從節(jié)點，并對其進行標示。從節(jié)點在獲得標示號后將自動與主節(jié)點進行測試信息交互，從而完成每個從節(jié)點上電子產(chǎn)品的檢測。
關(guān)鍵詞：CAN 總線，節(jié)點，探測算法
Abstract: A test platform of electronic products which based on the CAN bus technology
was constructed in this paper. As the bus technology used, this platform implemented the
electronic products test automatically. The key technology was the detection algorithm of auto node which added to the CAN bus. This algorithm divided the node of CAN bus into main node and sub-node. The main node would auto detect the sub-node, and mark it. Then the test information would be exchanged between sub-node and main node after the sub-node was marked, and the detection of the electronic products will be performed.
Key Words: CAN Bus, Node, Detection Algorithm
