[0026] The technical solutions in the embodiments of this specification will be described clearly and completely below in conjunction with the drawings in the embodiments of this specification.

[0027] The terms "first", "second", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "comprising" and any variation thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0028] The following is a detailed description of the automatic sample delivery method for a liquid scintillation instrument in conjunction with one or more embodiments.

[0029] Liquid scintillation instrument is a high-performance liquid scintillation analyzer, which is suitable for basic research and determination of radionuclides in environmental samples, especially for detecting trace release of alpha and beta radionuclides.

[0030] In the related art, the nuclear laboratory staff need to place the samples to be analyzed in the liquid scintillation instrument, and the opening and closing of the liquid scintillation instrument need to be manually participated. In laboratories with the risk of nuclear radiation leakage, this method cannot ensure the safety of laboratory staff, is inefficient, and is prone to errors.

[0031] In order to solve the problems existing in the related art, this specification proposes a method, system, electronic device and storage medium for automatic sample placement of a liquid scintillation instrument.

[0032] Combine the following Figure 1 The architecture involved in this positioning method is described in detail. Figure 1 , Figure 1 The structure diagram of an automatic sample delivery system provided by the embodiment of this specification is shown as follows: Figure 1 As shown, the system may include: a sample transport vehicle 11 and a plurality of liquid scintillation instruments (such as a liquid scintillation instrument 12 , a liquid scintillation instrument 13 and a liquid scintillation instrument 14 ).

[0033] The sample transport vehicle 11 is an intelligent electronic vehicle for sample transportation and sample delivery. The vehicle is equipped with a communication device for receiving instructions sent by the sample automatic delivery system and feeding back the results of the instruction execution to the sample automatic delivery system. The sample transport vehicle 11 also includes a sample storage space for placing samples and a mechanical arm for grabbing samples for delivery. These two parts will be described in detail later and will not be repeated here.

[0034] Each liquid scintillation instrument includes a switch device, which can be used to close the corresponding liquid scintillation instrument to avoid external interference with the liquid scintillation instrument during operation and avoid the risk of sample nuclear leakage. The opening and closing of the switch device is controlled by the sample automatic delivery system.

[0035] The automatic sample delivery system (referred to as the system) does not require human intervention in the process of transporting and delivering samples to be delivered into the liquid scintillation instrument. The transportation and delivery actions are completed by the transport vehicle. This not only avoids the harm caused by nuclear leakage to the staff, but also improves work efficiency and prevents operational errors caused by human involvement.

[0036] See also Figure 2 , Figure 2 FIG. 1 shows a flow chart of a method for automatically placing a sample in a liquid scintillation instrument provided in an embodiment of the present specification, such as Figure 2 As shown, the automatic sample delivery system includes a sample transport vehicle and a plurality of liquid scintillation instruments, each of which includes a switch device, and the switch device is used to close the corresponding liquid scintillation instrument. The automatic sample delivery method for the liquid scintillation instrument may at least include the following steps:

[0037] Step 202: In response to a sample to be placed on the sample transport vehicle, a target instrument to be placed and a target position of the target instrument are determined from the plurality of liquid scintillation instruments.

[0038] Specifically, the sample transport vehicle may be equipped with a camera, which can identify whether the sample to be placed is placed on the sample transport vehicle by taking videos or pictures. Alternatively, the sample transport vehicle may be equipped with other devices for identifying the sample to be placed, such as an infrared laser device, which is not limited in this specification.

[0039] In one embodiment, the automatic sample delivery system stores a correspondence between the number, operating status and position of each liquid scintillation instrument; determining a target instrument to be delivered and a target position of the target instrument from the multiple liquid scintillation instruments comprises: selecting any liquid scintillation instrument whose operating status is an idle state from the multiple liquid scintillation instruments as the target instrument, and determining the position of the selected target instrument as the target position according to the correspondence.

[0040] In the laboratory, the position of each liquid scintillation instrument is relatively fixed, and each liquid scintillation instrument is assigned a corresponding number for identification. The position and operating status of each liquid scintillation instrument can be determined based on the instrument number. The operating status of the liquid scintillation instrument can include idle state and working state. When the liquid scintillation instrument is in the working state, it indicates that samples have been placed in the liquid scintillation instrument and no more samples can be placed; when the liquid scintillation instrument is in the idle state, it indicates that samples have been placed in the liquid scintillation instrument and samples can be placed.

[0041] In this embodiment, the correspondence between the number, operating status and position of the liquid scintillation instrument stored in the automatic sample delivery system allows the system to select a target instrument from the liquid scintillation instruments in an idle state, thereby preventing the liquid scintillation instrument from being opened during operation, thereby ensuring the safety of the laboratory.

[0042] Furthermore, the liquid scintillation instruments whose operating state is idle among the multiple liquid scintillation instruments are candidate instruments; the selecting of any liquid scintillation instrument whose operating state is idle among the multiple liquid scintillation instruments as the target instrument includes: determining the corresponding positions of all candidate instruments according to the corresponding relationship, and determining the position of the sample transport vehicle; and selecting the candidate instrument closest to the position of the sample transport vehicle as the target instrument.

[0043] In the process of selecting the target instrument, any idle liquid scintillation instrument can be randomly selected as the target instrument, the candidate instrument closest to the sample transport vehicle can be selected as the target instrument, or the candidate instrument with the best performance can be selected as the target instrument. This specification does not limit this.

[0044] Step 204: When it is detected that the sample transport vehicle moves to the target position, a start instruction is sent to the target instrument to turn on the switch device of the target instrument.

[0045] The target position may be a position near the target instrument suitable for sample placement, which may be specifically set in advance by the system developer, for example, setting the target position twenty centimeters in front of the target instrument.

[0046] Each liquid scintillation instrument may be equipped with a camera, which can be used to determine whether the sample transport vehicle has reached the target position. Alternatively, the sample transport vehicle may be equipped with a camera, which can confirm whether the sample transport vehicle has reached the target position based on the relative position relationship between the target instrument and itself.

[0047] Step 206: determine the grabbing position of the sample to be placed, and send a grabbing instruction to the sample transport vehicle, so that the sample transport vehicle grabs the sample to be placed into the target instrument.

[0048] The grabbing position may be the position where the sample to be placed is placed on the sample transport vehicle. In actual situations, the sample transport vehicle may be loaded with multiple samples, and different samples may have different grabbing positions. The sample transport vehicle may place the samples at different grabbing positions into the corresponding liquid scintillation instrument.

[0049] Step 208: When it is detected that the sample to be placed is placed in the target instrument, a closing instruction is sent to the target instrument to close the switch device of the target instrument.

[0050] Similar to the sample transport vehicle, the liquid scintillation instrument may be equipped with a camera, which can be used to identify whether the sample to be placed is placed in the liquid scintillation instrument, or other devices for identifying the sample to be placed may be installed, such as an infrared laser device, which is not limited in this specification.

[0051] In this embodiment, in the process of transporting the samples to be placed and placing them into the liquid scintillation instrument, no human intervention is required, and the transportation and placement actions are completed by the transport vehicle, which not only avoids the harm caused by nuclear leakage to the staff, but also improves work efficiency and prevents operational errors caused by human participation.

[0052] In one embodiment, if Figure 3 As shown, the liquid scintillation instrument includes a base 31, a box body 32, a box cover 33 and a switch device, wherein the switch device is an external opening and closing hinge 34. The base 31 is located at the bottom of the liquid scintillation instrument, the box body 32 is fixedly mounted on the base 31, one side of the box cover 33 is connected to the box body 32, and both ends of the external opening and closing hinge 34 are rotatably connected to the base 31 and the box cover 33 respectively.

[0053] When the liquid scintillator is closed, the external opening and closing hinge 34 is Figure 3 When the liquid scintillator receives an opening command, the external opening and closing hinge 34 will rotate clockwise, thereby driving the box cover to open. When the liquid scintillator receives a closing command, the external opening and closing hinge 34 will rotate counterclockwise, thereby driving the box cover to close.

[0054] In this embodiment, the switch device is controlled by an external opening and closing hinge to eliminate the risk of nuclear leakage.

[0055] In one embodiment, if Figure 4 As shown, the sample transport vehicle includes a sample storage space 41 and a robotic arm 42, and the automatic sample delivery method further includes: in response to the sample transport vehicle receiving the grabbing instruction, controlling the robotic arm 42 to grab the sample to be delivered from the sample storage space 41 into the target container.

[0056] Furthermore, the automatic sample delivery system also includes a rack device, in which a plurality of sample-carrying racks are placed. The controlling of the robotic arm to grab the sample to be delivered from the sample storage space into the target container includes: controlling the robotic arm to grab the sample to be delivered onto any sample-carrying rack of the rack device, and controlling the robotic arm to grab any sample-carrying rack into the liquid scintillation instrument.

[0057] In actual situations, the sample is not directly placed into the liquid scintillation instrument, but is first placed on a sample support rack, and then the sample support rack is placed in the liquid scintillation instrument.

[0058] In one embodiment, the sample to be placed is a sample container containing a sample liquid, and each sample container has a corresponding sample number; when it is detected that the sample to be placed is placed in the target instrument, the automatic sample placement method also includes: identifying the sample number of the sample container placed inside the target instrument, and determining whether the identified sample number matches the sample number of the sample to be placed; when the identified sample number does not match the sample number of the sample to be placed, the sample container placed inside the target instrument is grabbed out and a warning is given to the user; the sending of a closing instruction to the target instrument includes: when the identified sample number matches the sample number of the sample to be placed, sending a closing instruction to the target instrument.

[0059] As mentioned above, in actual situations, a sample transport vehicle can be loaded with multiple samples, and different samples have different grabbing positions. The sample transport vehicle can place samples at different grabbing positions into the corresponding liquid scintillation instrument. The system can record the correspondence between the sample number and the number of the corresponding liquid scintillation instrument, and send matching instructions to each liquid scintillation instrument respectively. The matching instructions contain the sample number of the sample placed in each liquid scintillation instrument. After receiving the matching instruction, the liquid scintillation instrument can match the sample number in the matching instruction with the sample number of the sample placed in its own instrument. If there is no match, it means that the operation is wrong; if there is a match, the instrument is turned off.

[0060] In this embodiment, by matching the identified sample number with the sample number of the sample to be administered, the incorrect administration of the sample to be administered is avoided, thereby ensuring the accuracy of administration.
