The utility model relates to a communication card intellectual detection system device is gathered to electric power, including power module, communication card detection module, power module is equipped with the USB interface, through USB interface external power supply, communication card detection module is equipped with the DB9 interface, is connected with PC through the DB9 interface, and communication card detection module is equipped with the data transmission module, and the data transmission module inserts electric power 3A system. Carry out fault detection to the communication card through the communication test module among the communication card detection module, main including detect the communication card (all kinds of mobile communication cards, like the SIM card, the UIM card) whether there is physical damage, detect the communication card and whether can normally dial, whether detect the communication card can normal connection electric power 3A system. Through setting up a plurality of communication module, support the detection of many communication cards simultaneously, promote work efficiency more than several times, can realize the mutual of communication card and electric power 3A system, the fault type of communication card can be judged through the dialing process automatically, like damage, arrearage, network data mistake.
