Intelligent power distribution terminal based on ad-hoc network wireless communication

Abstract

The invention discloses an intelligent power distribution terminal based on ad-hoc network wireless communication. The terminal is used for connecting an external wireless router in a communication connection mode. The external wireless router is coupled to a power-distribution main station system through an optical fiber Ethernet. The terminal comprises a wireless communication module, a signal acquisition module, a data processing module and a safe access module. The safe access module comprises a certificate module and a signature module. The signature module is coupled to the data processing module and the wireless communication module. A main-station private key is stored in the external wireless router. By using the intelligent power distribution terminal based on the ad-hoc network wireless communication, through arranging the signal acquisition module, the data processing module and the wireless communication module, signals of a power grid can be effectively collected and transmitted into the power-distribution main station system; and through arranging the safe access module, the signal which is transmitted wirelessly is effectively encrypted so that safety of a message of an application layer is effectively increased.

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 charac
