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.
