[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 specification and claims of the present invention 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 may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0028] The following is a detailed description of the automatic sample delivery method for a nuclide measurement device in a nuclear power plant in conjunction with one or more embodiments.

[0029] In order to solve the problems existing in the above-mentioned related technologies, an embodiment of the present invention proposes a method and system for automatically placing samples in a nuclide measuring device of a nuclear power plant.

[0030] Combine the following Figure 1 The automatic sample delivery 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 automatic sample delivery system may include: a sample transport vehicle 11 and a plurality of nuclide measuring devices (such as a nuclide measuring device 12 , a nuclide measuring device 13 and a nuclide measuring device 14 ).

[0031] The sample transport vehicle 11 is an intelligent electronic vehicle for sample transportation and sample delivery. The intelligent electronic vehicle is equipped with a communication device for receiving instructions sent by the automatic sample delivery system and feeding back the results of the instruction execution to the automatic sample 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.

[0032] The nuclide measuring device includes a switch device, which can be used to close the corresponding nuclide measuring device to avoid external interference with the nuclide measuring device during operation and avoid the risk of sample nucleus leakage. The opening and closing of the switch device is controlled by the sample automatic delivery system.

[0033] This automatic sample delivery system does not require human intervention in the process of transporting the samples to be delivered and delivering them into the nuclide measuring device. The transportation and delivery actions are completed by the transport vehicle. This not only avoids the harm caused by nuclear leakage to the workers, but also improves work efficiency and prevents operational errors caused by human involvement.

[0034] See also Figure 2 , Figure 2 The following is a flow chart showing a method and system for automatically placing samples in a nuclear power plant nuclide measuring device according to an embodiment of the present specification. Figure 2 As shown, the automatic sample delivery system includes a sample transport vehicle and multiple nuclide measuring devices, each of which includes a switch device, which is used to close the corresponding nuclide measuring device. The automatic sample delivery method for the nuclide measuring device of a nuclear power plant may at least include the following steps:

[0035] 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 nuclide measurement devices (such as ORTEC instruments).

[0036] 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.

[0037] In one embodiment, the automatic sample delivery system stores the correspondence between the number, operating status and position of each nuclide measuring device; determining the target instrument to be delivered and the target position of the target instrument from the multiple nuclide measuring devices includes: selecting any nuclide measuring device whose operating status is idle from the multiple nuclide measuring devices as the target instrument, and determining the position of the selected target instrument as the target position based on the correspondence.

[0038] In the laboratory, the position of each nuclide measuring device is relatively fixed, and each nuclide measuring device is assigned a corresponding number for identification. The position and operating status of each nuclide measuring device can be determined based on the instrument number. The operating status of the nuclide measuring device can include idle state and working state. When the nuclide measuring device is in the working state, it indicates that a sample has been placed in the nuclide measuring device, and no more samples to be placed can be placed; when the nuclide measuring device is in the idle state, it indicates that a sample has been placed in the nuclide measuring device, and samples to be placed can be placed.

[0039] In this embodiment, by using the correspondence between the number, operating status and position of the nuclide measuring device stored in the automatic sample delivery system, the system can select the target instrument from the nuclide measuring device in the idle state, thereby preventing the nuclide measuring device from being opened during operation, thereby ensuring the safety of the laboratory.

[0040] Furthermore, the nuclide measurement devices whose operating status is idle among the multiple nuclide measurement devices are candidate instruments; the selecting any nuclide measurement device whose operating status is idle from the multiple nuclide measurement devices 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.

[0041] In the process of selecting the target instrument, any idle nuclide measuring device can be randomly selected as the target instrument, or 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.

[0042] 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.

[0043] 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.

[0044] Each nuclide measuring device 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.

[0045] 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.

[0046] 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 nuclide measurement device.

[0047] 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.

[0048] Similar to the sample transport vehicle, the nuclide measurement device may be equipped with a camera, which may be used to identify whether the sample to be placed is placed in the nuclide measurement device, or other devices for identifying the sample to be placed may be installed, such as an infrared laser device, and this specification does not limit this.

[0049] In this embodiment, in the process of transporting the samples to be placed and placing them into the nuclide measuring device, 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.

[0050] In one embodiment, the nuclide measuring device includes a lead can container, a support frame installed on the outside of the lead can container, and the switch device, wherein the switch device includes two rotating baffles installed at the opening structure of the lead can container, and the two rotating baffles are used to open and close the opening structure of the lead can container.

[0051] like Figure 3 As shown, the nuclide measuring device includes a lead tank container 31, a support frame 32, a first rotating baffle 33, and a second rotating baffle 34. The rotating baffle can be a semicircular closed component, one side of which is rotatably connected to the opening structure of the lead tank container, and the two rotating baffles are used to open and close the opening structure of the lead tank container 31.

[0052] In this embodiment, the lead tank container is automatically opened and closed by a switch device, thereby eliminating the risk of nuclear leakage.

[0053] Furthermore, the switch device also includes two retracting mechanisms, both ends of which are rotatably connected to the support frame and the rotating baffle respectively, and the end of the rotating baffle farther from the connection with the retracting mechanism is rotatably connected to the opening structure of the lead can container.

[0054] like Figure 3 As shown, the two ends of the first contraction mechanism 35 are rotatably connected to the support frame 32 and the first rotating gate 33 respectively, and the end of the first rotating gate 33 that is farther from the connection with the first contraction mechanism 35 is rotatably connected to the opening structure of the lead can container 31. The two ends of the second contraction mechanism 36 are rotatably connected to the support frame 32 and the second rotating gate 34 respectively, and the end of the second rotating gate 34 that is farther from the connection with the second contraction mechanism 36 is rotatably connected to the opening structure of the lead can container 31.

[0055] When the nuclide measuring device receives an opening command, the first retracting mechanism 35 and the second retracting mechanism 36 can rotate in the direction away from the lead can container 31, and the two retracting mechanisms can be shortened so that the first rotating gate 33 and the second rotating gate 34 are pulled open, thereby allowing the sample transport vehicle to place the sample to be placed into the lead can container 31; when the nuclide measuring device receives a closing command, the first retracting mechanism 35 and the second retracting mechanism 36 can rotate in the direction close to the lead can container 31, and the two retracting mechanisms can be extended so that the first rotating gate 33 and the second rotating gate 34 are merged, thereby closing the lead can container 31.

[0056] In this embodiment, the switch device is controlled by a contraction mechanism to eliminate the risk of nuclear leakage.

[0057] 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.

[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 nuclide measuring device. The system can record the correspondence between the sample number and the number of the corresponding nuclide measuring device, and send matching instructions to each nuclide measuring device respectively. The matching instructions contain the sample number of the sample placed by each nuclide measuring device. After receiving the matching instruction, the nuclide measuring device can match the sample number in the matching instruction with the sample number of the sample placed in its own instrument. If there is a mismatch, 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.
