Wireless network performance testing platform and method

Abstract

The present invention proposes a wireless network performance testing platform and method, including: an antenna feeder system, a frequency scanning system, and a business simulation system. The business simulation system is used to simulate actual business scenarios during rail transit operation to obtain various virtual business scenarios, In each simulated virtual business scenario, the antenna feed system radiates the first electromagnetic wave signal along the track, receives the second electromagnetic wave signal reflected along the track, and sends the second electromagnetic wave signal to the frequency scanning system, and the frequency scanning system The second electromagnetic wave signal is received, the electromagnetic wave signal is analyzed and processed to obtain electromagnetic environment parameters, and a wireless network model of rail transit is established by combining the electromagnetic environment parameters and the preset channel model, and the wireless network performance is tested according to the wireless network model. The wireless network performance test platform can realize the test of the wireless network performance of rail transit based on actual application scenarios even in the engineering survey process of the wireless network preliminary project.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless network performance testing platform and method. Background technique [0002] At present, most of the wireless network test schemes of rail transit systems are used in actual operation scenarios, using operating trains for follow-up test and maintenance. During the test and maintenance process, the operator needs to coordinate the cooperation of subsystems such as vehicles, power, line inspection, and dispatching. For example, according to the test results, the parameters such as the azimuth, downtilt, and antenna height of the trackside wireless access point (Wireless Access Point, AP) antenna are optimized and adjusted. Carry out high-voltage power outage, and connect the ground wire. At the same time, contact the engineering unit to assist in adjusting the above parameters, and re-perform the vehicle body inspection, whole line inspection, high-voltage powe...

Problems solved by technology

[0003] For the above test plan, during the engineering survey process of the wireless network preliminary project, due to reasons such as incomplete infrastructure such as conductive rails and the failure of operating vehicles to enter the site, it was impossible to implement tests based on actual application scenarios, which increased the difficulty and difficulty of subsequent wireless network optimization and maintenance. cost
