In order to improve the transmission and connection rates between the nodes of a power distribution field network, a hybrid multi-path dual-mode heterogeneous power distribution field network with high speed power broadband carrier and micro-power wireless communication capabilities is designed. First, the topological structure, the networking process and network maintenance mechanism of the field network are discussed. Secondly, a link measurement method based on a sliding window weighted average is designed, and hybrid multipath routing is calculated using a modified Bellman-Ford shortest path algorithm with limited hops and is refreshed in time intervals using the most recently used strategy. An adaptive multi-path parallel transmission dynamic decision-making algorithm is designed. Finally, the field network is applied to the power distribution information collection system, and tested in the laboratory and on site. The test results show that the dual-mode field network is more effective than the single-mode field network in increasing the copying rate and shortening the copying time.
