<p>Disclosed are an interference elimination method and device, the method comprising: determining whether the multiple frequency of an interference source working frequency interferes with a system working frequency; if the multiple frequency of the interference source working frequency interferes with the system working frequency, then adjusting the interference source working frequency. The present invention solves the problem that the interference elimination method in the relevant art cannot satisfy the requirements, thus achieving the effects of better interference elimination and lower cost.</p>
