Background The in vitro diagnostic industry is vigorous, and the continuous iterative upgrade of the automated technology of the medical laboratory is promoted. Currently, the IVD field is accelerating to complete the deep transformation from single machine automation to full laboratory automation (TLA), and the sample pretreatment system is used as a core link of the TLA system, and carries a series of key processes such as sample receiving, centrifugal treatment, uncapping and uncapping, sample cup separation, sorting and the like, and the automation level and the operation efficiency directly determine the treatment flux and the result reliability of the full detection flow. In the whole flow of sample pretreatment, the conveying and dispatching of the sample pipe frames are core hinges which are connected with each functional module in series and ensure the linkage of the system. Thousands to tens of thousands of samples are processed in modern clinical laboratories, and the types of the samples cover multiple priority scenes such as emergency treatment, routine examination, physical examination and the like, so that extremely high requirements are put on a conveying and scheduling system, not only are ordered circulation of sample tube frames realized, but also dynamic priority management is supported, and high-priority sample priority response is ensured. At present, a sample pipe rack conveying system applied in the industry is mainly realized by means of three technical schemes, namely a single-channel circulating conveying line and a circular track-based reciprocating conveying of a sample pipe rack, wherein the scheme has the defect of low channel utilization rate, cannot process multiple batches of samples in parallel, is difficult to realize the queue-inserting priority processing requirement of high-priority samples such as emergency treatment, and the like.
