A special variable terminal gprs communication test system and method

Abstract

The invention relates to a special transformer power supply mode terminal GPRS communication test system and a method. A electromagnetic shielding darkroom is installed in a test box body. An operation track is installed in a lower portion in the electromagnetic shielding darkroom. A tray is operated on the operation track through a stepping motor. A lower bottom top of the tray is provided with a tray lifting device. The tray lifting device is driven by a feeder motor. A tested special transformer power supply mode terminal can be placed in the tray. A integration tester and a signal interference apparatus are fixedly arranged above the electromagnetic shielding darkroom. A coupling antenna is fixedly arranged on a top end of the electromagnetic shielding darkroom below the integration tester. A warning lamp and a display are installed on the test box body. An electrical unit, a PLC control unit, a power supply system and a control unit are installed in the test box body. The system is formed by the electrical unit, a mechanical structure unit, the power supply system, the control unit, a feeder unit, a lifting positioning unit and an automatic conveying unit. Seamless coupling with an automatic assembly line is realized and a precedent that a GPRS communication module realizes whole performance detection on a special transformer power supply mode terminal whole machine is initiated.

Description

technical field [0001] The invention belongs to the field of electric power, and relates to the test of GPRS communication by a special transformer terminal in the smart grid technology, in particular to a GPRS communication test system and method of a special transformer terminal. Background technique [0002] As an objective requirement for the intelligent development of cities in the information society, smart grid is an important energy guarantee foundation and forerunner for the development of smart cities, and it is also an important content of smart city construction. The GPRS communication quality inspection of special transformer terminals is currently only carried out by the manufacturer of the uplink communication unit for functional testing. The special transformer terminal suppliers of State Grid Corporation have almost never carried out GPRS communication tests on the special transformer terminals before leaving the factory, and neither have the provincial netwo...

Problems solved by technology

[0003] According to industry knowledge, there is currently no detection device in China that realizes automatic and intelligent detection of GPRS communication for special transformer terminals, and there is no detection involving GPRS communication on the traditional special transformer terminal verification assembly line, especially it is impossible to simulate actual applications. Scenarios to collect radio frequency signal data, analyze and judge whether they meet the State Grid 1374.3-2013 communication unit technical specification and 1379.4-2013 communication unit inspection technical specification, so that the GPRS communication quality of the special terminal before installation cannot be evaluated, from the source avoid risk
