System and method of concentrator for testing wireless public network communication

Abstract

The invention relates to a system and a method of a concentrator for testing wireless public network communication. An electromagnetic shielding darkroom is installed in a test box body. An operating track is installed at the lower part inside the electromagnetic shielding darkroom. A tray runs on the operating track through a stepping motor. A tray jacking device is arranged at the lower bottom top of the tray. The tray jacking device is driven by a connection motor. A tested concentrator can be placed in the tray. An integrated tester and a signal interference device are fixedly arranged above the electromagnetic shielding darkroom. A coupled antenna is fixedly arranged at the top end of the electromagnetic shielding darkroom below the integrated tester. An alarm light and a displayer are installed on the test box body. The test box body is also internally provided with an electrical unit, a programmable logic controller (PLC) control unit, a power supply system and a control unit. The system comprises the electrical unit, a mechanical structure unit, the power supply system, the control unit, a connection unit, a jacking locating unit and an automatic convey unit. Seamless coupling with an automatic assembly line is realized, and a precedent that overall performance detection of a wireless public network communication module is realized on a complete concentrator is created.

Description

technical field [0001] The invention belongs to the field of electric power, and relates to the test of a concentrator for wireless public network communication in smart grid technology, in particular to a concentrator wireless public network 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. The wireless public network communication quality inspection of the concentrator is currently only carried out by the manufacturer of the uplink communication unit. There is no complete and comprehensive implementation plan, especially for the application of wireless technology for the comprehensive detection of concentrators and the detection on the whole machine by simulating the actual communication env...

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 wireless public network communication, and there is no detection involving wireless public network communication on the traditional concentrator verification assembly line, especially it is impossible to simulate the actual situation. To collect data of radio frequency signals in specific application scenarios, analyze and judge whether they meet the technical specifications of the State Grid 1374.3-2013 communication unit and 1379.4-2013 communication unit inspection technical specifications, so that the wireless public network communication quality of the concentrator before installation cannot be evaluated.
