After the cold storage and unloading of the vacuum blood collection tube 102 are finished at the cold storage interface module 03D, the second sample transfer frame becomes empty, the control system sends out an instruction, the transfer trolley 2 sends out from the point O, passes through the point B, the point C, the point D, the point G and the point H, reaches the point J and enters the cold storage interface module 03D; after the empty second sample transfer rack is loaded, the transfer trolley 2 passes through the point H, the point G, the point D, the point C, the point B, the point K1 and the point K2 to reach the point M2, and the second sample transfer rack is released to the point M2 for buffering; the transfer trolley 2 passes through the point K2, the point K1 and the point B and returns to the point O.

The sample transfer system then proceeds to the next cycle.

In practical application, if the transport capacity of the transport vehicle 2 is insufficient, multiple groups of transport vehicles 2 may be provided, which are respectively defined as a first transport vehicle 2, a second transport vehicle 2, a third transport vehicle 2, and the like, and the initial positions corresponding to each group of transport vehicles 2 are respectively defined as O1 point, O2 point, O3 point, and the like.

The main rooms of the examination department include, but are not limited to, sorting rooms, examination rooms, refrigerating rooms, blood collection rooms, centrifugal rooms, AGV waiting rooms, etc.

The transfer units 3 of each room are not limited to 1 group, but may be plural groups.

The multi-group sample rack 1 has only two states: a vacuum blood collection tube 102 and a non-vacuum blood collection tube 102 are provided; only at each transfer unit 3a systematic distinction is made, no distinction being made in the buffer.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other. Any combination of all the embodiments provided in the present invention is within the protection scope of the present invention, and will not be described herein.
