The invention relates to an automatic detection method compatible with an electric energy meter and a concentrator carrier module. A detection system comprises a down-pressing power-up module, a CCD detection module and a transfer box module, wherein the transfer box module is installed in the detection system in a guiding and moving mode, the down-pressing power-up module and the CCD detection module are installed at the positions, above the transfer box module, in the detection system in a guiding and moving mode. According to the detection method and system, single-phase and acquisition terminal modules can be detected correspondingly, time waste caused by wire replacement of equipment is avoided, the cost of the detection equipment is reduced, the space utilization rate is improved, the manual participation is reduced, the product detection efficiency can be greatly improved, the blank of state grid carrier module metering automatic production detection is filled up, the carrier replacement time among all procedures can be saved, the time waste caused by wire replacement of the equipment is avoided, the cost of the detection equipment is saved, the space utilization rate is improved, the manual participation is reduced, and the product detection efficiency can be greatly improved.
