The utility model relates to an electric power wireless signal access circuit. The electric power wireless signal access circuit comprises a controller, a public network module, a special network module, a power supply module, a special network signal recognizer and a public network signal access circuit. And the universal pin of the controller is connected with the enabling end of the power supply module and is used for connecting the power supply module when an enabling signal is output to the enabling end of the power supply module. The output end of the power module is connected with the power supply end of the special network module. And each data pin of the controller is respectively connected with the signal output end of the special network module and the signal output end of the public network module. And a reset pin of the controller is connected with a reset end of the special network module. And the signal input end of the special network module is connected with the special network signal recognizer. And the signal input end of the public network module is connected with the public network signal access circuit. And the public network signal access circuit is used foraccessing the public network signal identifier. Rapid access of electric power wireless signals is realized, and the complexity of an electric power wireless signal access circuit is reduced.
