基于433频段无线传输的试验研究
Experimental study on wireless transmission based on 433 frequency band
摘要
Abstract
In view of the factors affecting on the wireless transmission quality in actual production environment,the solid-state vinegar brewing control system is combined to perform the experimental study for the wireless transmission module working at 433 MHz. The experiments of electromagnetic wave interference and obstacle with different materials existing in mechanical equipment influencing on the attenuation loss of wireless signal,transmission characteristics among different rooms and different floors,and bit error rate of different transmission distance in specific environment were carried on. The bit error rate,transmis-sion loss,signal intensity,transmission distance and other indicators are measured emphatically. The experimental results can provide the reference for the design of wireless transmission system.关键词
