A concentrator gprs communication test system and method

Abstract

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.

Description

technical field [0001] The invention belongs to the field of electric power, and relates to the test of GPRS communication by a concentrator in the smart grid technology, in particular to a concentrator GPRS communication test system and method. 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. Concentrator GPRS communication quality testing is currently only carried out in the uplink communication unit manufacturers. The concentrator suppliers of the State Grid Corporation of China have almost never conducted GPRS communication tests on the concentrators before leaving the factory. The provincial network measurement centers of the State Grid do not have a complete, A comprehensive implementation plan, especially for the applicati...

Problems solved by technology

[0003] According to industry knowledge, there is currently no detection device in China to realize automatic and intelligent detection of concentrator GPRS communication, and there is no detection involving GPRS communication on the traditional concentrator verification assembly line, especially it is impossible to simulate actual application scenarios. Collect the data of radio frequency signals, 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 concentrator before installation cannot be evaluated, and risks can be avoided from the source
