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.
