The communication network in the distribution station area has many pain points and difficult problems, such as a wide range of points, a large number of equipment, a large amount of data, and slow response speed. Improving the field network performance and communication security reliability is an urgent problem to be solved in the construction of the power distribution Internet of Things. In this paper, a new algorithm of power line carrier and wireless communication carrier aggregation is designed, which mainly includes subcarrier optimization calculation, carrier aggregation based on clustering, carrier aggregation update, etc. The combination of subcarrier reliability optimization and network clustering is used for carrier aggregation of power line carrier and wireless integrated communication. At the same time, a field area network security communication method based on the combination of Physical Unclonable Function (PUF) message security encryption and relay node security verification is proposed to improve the security and reliability of power equipment body area network deployment. The test results show that the method proposed in this paper can give consideration to both the acquisition success rate and the acquisition security, and has the promotion value.
