A concentrator wireless public network communication test system and method

Abstract

The invention relates to a concentrator wireless public network communication test system and method. An electromagnetic shielding darkroom is installed in the test box, and a running track is installed on the lower part of the electromagnetic shielding darkroom, and a tray is run on the running track by a stepping motor. A tray lifter is installed on the lower bottom of the tray. The tray lifter is driven by a connecting motor, and the tested concentrator can be placed in the tray; a comprehensive tester and a signal interference device are fixed above the electromagnetic shielding darkroom. The top of the electromagnetic shielding darkroom below the comprehensive tester is fixed with a coupling antenna; an alarm light and a display are installed on the test box, and an electrical unit, PLC control unit, power supply system and control unit are also installed in the test box. This system is composed of electrical unit, mechanical structure unit, power supply system and control unit, connecting unit, jacking positioning unit, and automatic conveying unit. It is a precedent to realize full performance testing on the whole machine.

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...

AI Technical Summary

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. Avoid risks from the source
