Network selection method power wireless-communication heterogenous multi-network environment

The invention provides a network selection method in the power wireless-communication heterogenous multi-network environment. The method comprises the following steps: S1, intercepting the service request sent by a terminal, or intercepting signals of networks, where the terminal is located, and judging whether the networks is in a performance degradation state or not according to the intercepted network signals; S2, triggering the network selection: according to the service type and the network performance, building a network selection model, determining the decision attributes of the network, sorting candidate networks according to the decision attributes, and screening the optimal network. According to the network selection method provided by the invention, the candidate networks can be sorted well, and the optimal network can be screened out for allowing the terminal of power equipment to be accessed, so that the communication service quality of an electric power system is guaranteed, and the resource uti
