Concentrator GPRS communication test system and method

The invention relates to a concentrator GPRS communication test system and a concentrator GPRS communication test method. An electromagnetic shielding dark room is installed in a test box. Operating rails are installed in the lower part of the electromagnetic shielding dark room. A tray is operated on the operating rails via a stepping motor. A tray jacking device abuts against the lower bottom of the tray and is driven by a connection motor, and a to-be-tested concentrator can be placed in the tray. A general-purpose tester and a signal interference device are fixedly arranged above the electromagnetic shielding dark room. A coupled antenna is fixedly installed at the top end of the electromagnetic shielding dark room under the general-purpose tester; an alarm light and a display are arranged at the test box. An electric unit, a PLC control unit, a power supply system and control unit are arranged in the test box. The system is composed of the electric unit, a mechanical structure unit, the power supply system and control unit, a connection unit, a jacking location unit and an automatic conveying unit, and achieves seamless coupling with an automated assembly line, thereby setting a precedent that a GPRS communication module can be subjected to overall performance testing in a complete concentrator.
