摘要: 本发明涉及一种工业无线网络的组网优化方法,在组网过程中包括以下步骤:在超帧中部增加一个网关广播时隙,使单位时间内网关发送广播报文的数量增加;待入网节点接收该广播报文添加为候选邻居;选定同步点,进行时间同步;采用冲突检测进行邻居发现,找出双向邻居节点;待入网节点从邻居表中选出排列在最前面的双向邻居节点为代理节点,向其发送加入请求报文,代理节点转发该请求报文到网关;网关收到加入请求报文后为待入网节点分配网络资源,并以无线报文的形式下发到节点;所有资源分配报文都发送完毕,组网过程结束;本发明大幅度的缩短了组网时间,提高了加入时隙资源的使用效率,使网络资源分配更加合理。
英文摘要: The invention relates to a networking optimization method for wireless networks for industrial automation. The networking process comprises the following steps: adding a gateway broadcast time slot in the middle of a superframe so as to increase the number of broadcast messages sent by a gateway every unit time; a node to be accessed to an internet receiving the broadcast messages and adding candidate neighbors; selecting synchronization points to carry out time synchronization; utilizing collision detection to perform neighbor finding to find out bidirectional neighbor nodes; the node to be accessed to the internet selecting the bidirectional neighbor node, which ranks in the front, as an agent node from a neighbor table and sending a join request message to the agent node; the agent node forwarding the request message to the gateway; after receiving the join request message, the gateway allocating network resources to the node to be accessed to the internet, with the network resources being distributed to the node in a wireless message manner; and after all resource allocation messages are sent, the networking process is over. The networking optimization method greatly reduces networking time, improves the usage efficiency of join time slot resources, and enables the network resource allocation to be more reasonable.
