Portable carrier module detector

The invention discloses a portable carrier module detection which comprises a detection mainboard, a display, a keyboard, a power supply and a panel. The detection mainboard comprises a processor, a storage chip, a crystal oscillation circuit and a JTAG conversion terminal; the processor is provided with a first serial port, a second serial port and a third serial port which are detachably connected with a 09-version three-phase carrier module, a 13-version carrier module and a single-phase carrier module respectively through the JTAG conversion terminal. Data demands are sent by the point copying principle of a processor analog concentrator, and whether or not a to-be-detected device fails is judged by the fact whether processors or to-be-detected smart electric meters reply data. The portable carrier module detector is compatible to the 13 and 09-version three-phase carrier modules and applicable to the carrier modules of concentrators with fault detected offline and the carrier modules of the smart electri
