Abstract
The wireless performance test of Wi-Fi & BT is an important part of the development process of smart home appliances,and the test results of wireless performance can provide a more valuable basis and reference direction for the pre-design optimization of smart home appliances.In order to meet the wireless performance test requirements of large-scale intelligent home appliances,adopt a large 1/4 ring structure multi-probe OTA darkroom test system.In the darkroom,22 probes are distributed in the range of 0°～105° in the vertical plane,and a dense sampling interval of 5° can be realized at least.The smart home appliances to be tested are rotated in the one-dimensional rotary table in the range of 360° to realize the sampling of data in more than half of the space,and the upper computer of the OTA darkroom test system applies algorithms to the processing of the collected data,and obtains wireless performance parameters of the smart home appliances to be tested.The system in the TIRP test,TIRS test theoretical derivation and calculation,and based on the"Golden sample"and Shenzhen Moore Huanyu Communication Technology Company's full-ring multi-probe OTA darkroom system test comparison demonstration,the two systems in the TIRP test item of the maximum error of 0.51 dB,in the TIRS test item of the maximum error of 0.36 dB,the test error is within the permissible range.Proved the OTA darkroom test system can effectively,accurately and quickly test the wireless performance of large-scale intelligent home appliances.关键词
