Problems solved by technology
However, in practice, it is found that the installation position deviation of the photoelectric transmitter and photoelectric receiving plate of the photoelectric sensor on the sample transmission device, the difference in the photoelectric performance of the photoelectric sensor, and environmental interference are common, which often leads to the test tube rack blocking the photoelectric transmitter of the photoelectric sensor. The emitted photoelectric signal, but the intensity of the photoelectric signal received by the photoelectric receiving plate of the photoelectric sensor is not 0, so the position of the test tube rack cannot be accurately located

Embodiments of the invention disclose a test tube rack positioning method, a sample transmission device and a storage medium. The method comprises the following steps: firstly, acquiring first movement information of a test tube rack relative to an initial position from a first corresponding relation by utilizing a signal intensity threshold value when the middle position of a first shielding area shields a photoelectric signal emitted by a first photoelectric emitter; and then acquiring a second movement information of the test tube rack relative to the initial position according to the first movement information and standard width information of the first shielding area when a first side edge shields a photoelectric signal emitted by the first photoelectric emitter. . By implementing the method, accurate positioning of the test tube rack is realized.
Description
technical field [0001] The present application relates to the technical field of medical devices, in particular to a test tube rack positioning method, a sample transmission device and a storage medium. Background technique [0002] In the sample transfer device, most of the test tube racks are positioned by photoelectric sensors. However, in practice, it is found that the installation position deviation of the photoelectric transmitter and photoelectric receiving plate of the photoelectric sensor on the sample transmission device, the difference in the photoelectric performance of the photoelectric sensor, and environmental interference are common, which often leads to the test tube rack blocking the photoelectric transmitter of the photoelectric sensor. The emitted photoelectric signal, but the intensity of the photoelectric signal received by the photoelectric receiving plate of the photoelectric sensor is not 0, so the position of the test tube rack cannot be accurately ...
