The invention relates to an electric energy meter carrier wave communication detection method for an automatic detection assembly line. In the case of overall meter detection, the attenuation test ofcommunication novel energy can be realized, whether the continuous welding, missed welding, device damage and other conditions of electronic elements and devices in a carrier wave module can be discovered, and the product reliability of the module can be effectively ensured. By adopting the method, the existing detection apparatus is not severely changed, the method can be completed in a case of no electromagnetic shielding box, and meters and gauges for detecting a narrow-band carrier wave module and a broadband carrier wave module can be compatible.
