Business control method used in industrial wireless network, and system thereof

The invention relates to a business control method used in an industrial wireless network. The industrial wireless network comprises a business control server and a plurality of local area networks. Each local area network comprises a sink node and a plurality of wireless terminals. The method comprises that the plurality of wireless terminals in each local area network periodically report terminal characteristic information to the business control server through the sink node of the corresponding local area network. According to the terminal characteristic information, the business control server selects one wireless terminal from the plurality of wireless terminals as the routing node of the local area network. A distance vector routing algorithm is operated in the routing node to obtain the network topology information of the local area network. The routing node reports the network topology information of the local area network to the business control server. The business control server carries out merging of the network topology information of the plurality of local area networks, thereby obtaining the network topology information of the industrial wireless network and carrying out data processing according to initiated business types.
