摘　　要：ＤＮＰ３．０ 通信规约规定子站能够自发响应向主站上报变化信息，适合于作为配电自动化的现场智能终端与控制主站之间的通信规约。文中简单介绍了ＤＮＰ３．０ 规约的构成，重点介绍了自发响应消息在传输时及应用层处理时可能发生的碰撞情况，以及ＤＮＰ３．０WT9.,8.5BZ] DNP3.0 (Distributed Network Protocol version 3.0) supports unsolicited response to enable RTU to send exception information to master station. It is suited to use in point to multi point communication in distribution automation. This paper mainly presents the message transition collision problems in data link and application layer caused by RTU unsolicited responses. The mechanism used by DNP protocol to deal with message transition collisions is discussed.
