Collision-free process technology for arrayed multipoint devices in coffee machines

Coffee machines have become very popular in recent years, but their lack of functionality still requires a great deal manual maintenance, which inevitably has many hidden dangers. with radio frequency identification systems (RFID) are more effective reducing losses due to labor, and increasing efficiency. However, collision problems RFID can seriously affect the performance system. In this paper, we propose specific solution such by proposing collision-free process technology for arrayed multipoint devices. And technique is successfully applied coffee machine. Through design experiments, after 10,000 repeated tests, no error occurred. The problem collisions mechanisms been solved.
