中文摘要	本发明涉及一种面向工业无线网络的低开销高可靠资源分配方法。本发明对新加入的现场设备进行路径分配；网关设备获取并整合现场设备所需的资源；资源多播传输；末端的新加入的现场设备在接收到正确的资源分配报文后，一段时间内网关设备未收到新加入现场设备的应答，按照原路径再次发送该资源。本发明采用中心调度保证了资源分配的最优性；采用路径扩展算法的路由分配方式，简化了路由分配方法，便于网络维护；采用多播的资源分配方式，一方面提高资源分配效率，降低了网络负荷，另一方面减少了报文的传输次数，增加了现场设备入网的成功率；采用超时重传机制，保证了资源报文的可靠传输。

英文摘要	The invention relates to a low-overhead and high-reliability resource distribution method for an industrial wireless network. The low-overhead and high-reliability resource distribution method for the industrial wireless network comprises the steps of carrying out route distribution on new field equipment, obtaining a gateway device and integrating resources needed by the field equipment, carrying out multicast transmission on the resources, and sending the resources again along an original route when new field equipment at the tail end receives a correct resource distribution message and the gateway device does not receive a response of the new field equipment in a period. According to the low-overhead and high-reliability resource distribution method for the industrial wireless network, optimality of the resource distribution is guaranteed due to the adoption of a central dispatching method, a route distribution method is simplified due to the fact that a route distribution method of a route extension algorithm is adopted, the network can be maintained conveniently, due to the fact that the multicast resource distribution method is adopted, resource distribution efficiency is improved and load of the network is reduced on one hand, and the frequency of the transmission of the message is reduced and the success rate of network access of the new field equipment is increased on the other hand, and the reliability of the transmission of the message is guaranteed due to the fact that a retransmission timeout mechanism is adopted.
