Description

Technical Field

[0001] The present application relates to the field of code supplementation scanning technology, and in particular to a mobile plasma bag code supplementation scanning device, method and medium. Background Art

[0002] At present, the plasma bag scanning workflow is: the plasma to be tested is stored in a -20℃ high-bay cold storage in 1 stack of 16 trays, with 32 bags on each tray. After the automated plasma picking system starts, the system automatically issues instructions for the plasma to be tested to be removed from the warehouse. The plasma to be tested is picked out of the -20℃ high-bay cold storage in stacks. After preliminary screening, plasma of the same effective value will be grabbed by the robot and placed in the trays on the corresponding tracks. Every row of each tray contains eight bags. When the tray is full of eight bags, the trolley carrying the tray will automatically step forward to reserve space for eight bags in the next row. The eight bags of plasma are then scanned. There is a scanning device above each position in this row. When the tray steps forward, the plasma in the tray is scanned and bound to the position.

[0003] The current problem is that when the eight bags of plasma are placed for scanning, there are eight barcode scanning devices above the row. When the tray is stepped, the plasma in the tray is scanned and bound. Because some plasma is not placed correctly or in an inappropriate position, the scanner cannot obtain the corresponding information (i.e., not scanned), and needs to be re-scanned. The current method of supplementary scanning is that when the plasma bag is not scanned alarm, the plasma picking system stops, and the control room staff uses the intercom to check the alarm to tell the on-site staff, and then the on-site staff goes to the corresponding alarm track to take out the unscanned plasma bag, put the unscanned plasma bag back on the conveyor belt, and then notify the control room staff to start the plasma picking program, and the robot grabs it and puts it back in the tray for scanning. The whole process takes at least 2 minutes. There are 50 alarms per day on average, and it takes nearly 2 hours to process the alarm plasma, and it requires the cooperation of multiple people. Summary of the invention

[0022] The technical solution proposed in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0023] This application Figure 1 A mobile plasma bag scanning device is provided in the embodiment of the present application. Figure 1 As shown, the system provided in the embodiment of the present application mainly includes: The linear transport platform 1 is a transport platform for placing plasma bags.

[0024] The tray conveying track 2 is a transport device for transporting the plasma bag from the placement position to the fixed scanner module 4 and the supplementary scanning module 5, and is composed of existing connecting gear belts, belt tracks, gears and other components.

[0025] In addition, in order to avoid too fast a speed to collect data in time, the pallet conveying track 2 includes a speed controller, and the speed controller is connected to the central control system.

[0026] The plasma tray 3 is a tray for holding blood bags. For example, each tray is divided into 4 rows according to the placement position, each row has 8 columns, and each row is full of eight blood bags.

[0027] The fixed scanner module 4, specifically, has a plurality of fixed scanners fixed thereon, and are respectively connected to the central control system circuit, so as to preliminarily scan and obtain the plasma information of the plasma bag.

[0028] The supplementary code scanning module 5 at least includes: an encoding controller 51 , a servo motor 52 , a linear slider track 53 , a scanner moving slider 54 , a moving scanner 55 , and a support frame 56 .

[0029] The encoding controller 51 controls the servo motor 52 according to the data fed back by the central control program, and the servo motor 52 drives the scanner moving slider 54 to move on the linear slider track 53. The support frame 56 is a fixing device for supporting the linear slider track 53 on the tray conveying track 2. In addition, in order to enable the scanner moving slider 54 to scan plasma bags at as many positions as possible, the length of the linear slider track 53 in the supplementary scanning module 5 can be greater than or equal to the width of the tray conveying track 2.

[0030] Based on the above description, the present application discloses a mobile plasma bag supplementary code scanning device, wherein a tray conveying track 2 is fixed on a linear transport platform 1, a plasma tray 3 is placed on the tray conveying track 2, a fixed scanner module 4 and a supplementary code scanning module 5 are arranged above the linear transport platform 1, and during the track operation, the plasma tray 3 first passes through the fixed scanner module 4 and then passes through the supplementary code scanning module 5. When the plasma tray 3 drives the plasma bag to move to the fixed scanner module 4, the fixed scanner corresponding to the position of the plasma bag on the fixed scanner module 4 initially obtains the plasma bag information. Return to the central control system; the central control system obtains the position of the unreturned information based on the returned plasma bag information, and sends the position to the encoding controller 51 of the supplementary code scanning module 5, and the encoding controller 51 controls the servo motor 52 to drive the scanner moving slider 54 to move from the linear slider track 53 to the corresponding position, and then collects the missing plasma bag information through the mobile scanner 55 fixed on the scanner moving slider 54. The plasma bag information is uploaded to the central control system through the mobile scanner 55.

[0031] In addition, the supplementary code scanning module 5 includes an LED prompt light, and the LED prompt light is connected to the central control system circuit, and is used to switch the prompt light color according to whether there is a location that has not returned information.

[0032] In addition, the embodiment provides a mobile plasma bag supplementary scanning method, such as Figure 2 As shown, the method provided in the embodiment of the present application mainly includes the following steps: Step 210: Scan the identification code of the plasma bag on the tray conveyor track by using a plurality of fixed scanners on the fixed scanner module to obtain the plasma bag information; upload the plasma bag information to the central control system by using a plurality of fixed scanners.

[0033] It should be noted that in order to ensure that the information of each blood bag can be collected, the number of fixed scanners is consistent with the number of plasma bags normally placed in the same tray row.

[0034] Step 220: When the central control system detects that the number of plasma bag information collected from the same tray row is less than a preset number, the collection position of the missing plasma bag information is obtained.

[0035] This step may be specifically as follows: when the central control system detects that the number of plasma bag information collected on the same tray row is less than a preset number, the collection position of the missing plasma bag information is obtained based on the preset position of the fixed scanner that uploads the plasma bag information.

[0036] It should be noted that the preset positions of various fixed scanners are pre-stored in the central control system, and the central control system can obtain the collection position of the missing plasma bag information based on the preset position of the fixed scanner that uploads the plasma bag information.

[0037] Step 230, reduce the speed of the tray conveyor track to a preset minimum speed, control the servo motor through the encoding controller, and then drive the scanner to move the slider to the collection position of the missing plasma bag information, and collect the plasma bag information through the scanner on the scanner moving slider.

[0038] Step 240: Transmit the plasma bag information to the central control system via a scanner.

[0039] In addition, in order to increase the processing speed, after the plasma bag information is transmitted to the central control system through the scanner, the present application can restore the speed of the tray conveying track to the preset normal speed.

[0040] In addition, in order to improve the prompt effect, the method also includes: controlling the specific color of the LED prompt light according to the actual speed of the pallet conveying track.

[0041] As an embodiment, the method can be specifically as follows: the plasma to be tested is stored in a -20℃ high-bay cold storage in 1 stack of 16 trays, with 32 bags in each tray. After the automated plasma picking system starts, the system automatically issues an instruction for the plasma to be tested to be removed from the cold storage at -20℃ high-bay. The plasma to be tested is picked out of the -20℃ high-bay cold storage in stacks for plasma picking, and then undergoes preliminary screening. Plasma of the same effective value will be grabbed by the robot and put into the tray of the corresponding track. Each tray is divided into 4 rows according to the placement position, with 8 columns in each row. When a row of eight blood bags is filled (at this time, it is in the unscanned state in front of the scanner), the tray transfer conveyor carrying the tray will automatically step forward to reserve space for eight bags in the next row. As the eight bags of plasma are stepped forward, eight scanners simultaneously perform high-speed scanning on the plasma in the tray to bind the plasma bag (plasma) information.

[0042] When the scanner cannot obtain the corresponding information (i.e., unrecognized state) due to incorrect placement or inappropriate position of individual plasma, and needs to be re-scanned, the plasma picking program is suspended, and the central control system automatically transmits the unscanned plasma position to the encoding controller of the re-scanning module. The encoding controller controls the servo motor to drive the scanner to move the slider to the plasma position (collection position). The scanner moves the slider to scan the unscanned plasma barcode for re-scanning at a high frequency; after identifying the plasma bag (plasma) information, the plasma picking program continues to run, and the robot continues to grab the plasma and place it in the tray for scanning. The re-scanning time only takes 3-10 seconds due to inconsistent moving distances.

[0043] In addition, an embodiment of the present application further provides a non-volatile computer storage medium on which executable instructions are stored. When the executable instructions are executed, a mobile plasma bag re-scanning method as described above is implemented.

Without departing from the technical principles of the present disclosure, those skilled in the art can split and combine the technical solutions in the above-mentioned various embodiments, and can also make equivalent changes or replacements to the relevant technical features.
