Communication method based on Ad-Hoc network wireless communication

Abstract

The invention discloses a communication method based on Ad-Hoc network wireless communication. The method comprises the steps that 1 an application interface layer is set in a distribution master station system; 2 a signal acquisition interface layer is connected with a signal acquisition module; 3 the signal acquisition module in step 2 is used to acquire a secondary device signal of a power grid, and then the acquired secondary device signal is transmitted to a wired communication interface layer in a wired manner; and 4 a master station private key is preloaded in a data storage layer. According to the communication method based on Ad-Hoc network wireless communication, the application interface layer is effectively set in the step 1 to receive the signal; the signal can be effectively acquired in the step 2; the signal is effectively encrypted and transmitted in the step 3; and the received encrypted signal is effectively decrypted and transmitted to the application interface layer in the step 4.

Problems solved by technology

[0003] The distribution communication network is an important part of the distribution automation system. The monitoring, control and fault handling of the distribution network operation status all rely on the communication network to achieve. The use of Ethernet passive optical network technology is undoubtedly a better choice. However, due to urban construction and power line planning, there are factors such as difficulties in optical cable construction and high deployment costs. Therefore, wireless communication solutions are considered to realize distribution automation data collection. At present, the mainstream solution is to use wireless public network communication and distribution network data utilization. GPRS / CDMA, 3G / 4G carry out data transmission, but due to the characteristics of the public application of the public communication network, the public network is shared by users, and the service bandwidth and security are not guaranteed. Therefore, the data transmission application is suitable for a small amount of or sudden data transmission

The initial investment is small and the effect is quick. However, due to the nature of lease, there are problems such as security, controllability, and long-term economics compared with private network communications. It is not suitable for large-scale private network needs of power automation.

[0004] On the other hand, with the increasing complexity of communication conditions, communication security, especially the security of remote control in power distribution applications, has become increasingly prominent
