The utility model relates to a detection device for the carrier communication module of a single-phase intelligent electric energy meter, and particularly relates to the mass detection for the carrier communication modules of single-phase intelligent electric energy meters. The detection device for the carrier module of the single-phase intelligent electric energy meter comprises a communication unit and a signal processing circuit arranged in the device. The communication unit is composed of a transformer, an isolator, a meter reading controller and an attenuator. The signal processing circuit comprises a micro-controller, a data storage module, a power supply module, a carrier communication module interface and an acousto-optic indication module. The above detection device can be used for the detection of carrier communication modules of various solutions. The automation level of the detection of carrier communication modules is improved. Meanwhile, the device can detect six carrier communication modules at the same time, so that the detection efficiency is improved. The phenomena of false detection and leak detection due to the manual operation in the prior art can be avoided.
