The invention relates to an unshielded automatic detection system for single-phase electric energy meter broadband carrier modules. The system comprises an MDS, a PC, a detection tool, an appearance and identification detection device and a test master device; the MDS is connected with the PC through a data cable; the PC is connected with the detection tool through a data cable; a detection tool controller and six module wiring terminals which are connected with the single-phase electric energy meter broadband carrier modules are arranged in the detection tool; and the PC is connected with theappearance and identification detection device and the test master device. The unshielded automatic detection system of the invention has the advantages of compatibility with the detection of single-phase and three-phase modules, automatic logistics, automatic warehousing and the like. With the unshielded automatic detection system of the invention adopted, blanks in state grid carrier module measurement automatic production warehousing logistics and detection can be filled; time for carrier replacement between various processes can be saved; time waste caused by the line change of devices can be avoided; detection equipment costs can be decreased; a space utilization rate can be improved; module out-box and in-box processes can be omitted; human involvement can be reduced; and product detection efficiency can be greatly improved.
