In some examples, step S140 may be performed after the PBS solution is prepared in the first solution tank 11, by dissolving a target weight of glucose solute in the PBS solution beaker 2 having a PH within a first predetermined range to form a glucose solution, which may be poured into the second solution tank 12.

In some examples, the PBS solution having a pH within the first predetermined range may be poured into beaker 2 a plurality of times, beaker 2 may be shaken, and then the glucose solution in beaker 2 may be poured into second solution tank 12 a plurality of times.

In some examples, the control module 13 controls the first solution tank drawing pump 117 and the first solution tank peristaltic pump 118 to draw the PBS solution of the first solution tank 11 to the second solution tank 12 (step S150).

In some examples, in step S160, the second measurement module measures the amount of solution of the second solution tank 12, and the control module 13 controls the conveyance speed of the PBS solution according to the amount of solution of the second solution tank 12.

In some examples, the measurement value of the second measurement module may be the weight of the solution in the second solution tank 12 measured by the second weighing apparatus 121 (see fig. 5). In other examples, the measurement value of the second measurement module may also be the level of the solution in the second solution tank 12 measured by the second level sensor. Thereby, the second measuring module can measure the amount of solution in the second solution tank 12.

In some examples, when the measured value of the second measurement module of the solution in the second solution tank 12 is lower than the fourth predetermined value, the control module 13 may issue an instruction to the first solution tank pump 117, and the first solution tank pump 117 conveys the PBS solution that is pumped in the first solution tank 11 to the second solution tank 12, and the speed of conveyance of the PBS solution is the seventh conveyance speed.

In some examples, when the measured value of the second measurement module of the solution in the second solution tank 12 reaches the fourth predetermined value, the control module 13 may issue a command to the first solution tank pump 117, and the first solution tank pump 117 will adjust the conveyance speed of the PBS solution in the first solution tank 11 to the second solution tank 12 to be the eighth conveyance speed.

When the module measurement reaches the fifth predetermined value, the control module 13 may issue a command to the first solution tank pump 117, and the first solution tank pump 117 stops pumping the PBS solution of the first solution tank. The control module 13 sends a command to the first solution tank peristaltic pump 118, the first solution tank peristaltic pump 118 pumps the PBS solution of the first solution tank 11 and conveys the PBS solution into the second solution tank 12, and the conveying speed of the first solution tank peristaltic pump 118 pumping the PBS solution to the first solution tank 11 is a ninth conveying speed.

In some examples, control module 13 may also adjust first solution tank peristaltic pump 118 to pump PBS solution from first solution tank 11 to second solution tank 12 at a tenth, eleventh, or twelfth delivery rate based on measurements of a second measurement module of solution in second solution tank 12. Thus, the control module 13 can slowly add liquid to the second solution tank 12 by controlling the liquid adding speed of the first peristaltic pump 118, which can be advantageous for controlling the amount of solution in the second solution tank.

In some examples, control module 13 may also control the rate of delivery of the PBS solution from first solution tank 11 to second solution tank 12 based on a measured difference between the amount of solution in second solution tank 12 and a preset target weight of the second solution tank 12 formulation solution. In some examples, when the measured difference between the amount of solution in the second solution tank 12 and the preset target weight of the solution formulated by the second solution tank 12 is the fourth difference, the control module 13 issues an instruction to the first solution tank pump 117, and the first solution tank pump 117 will pump the PBS solution of the first solution tank 11 and deliver to the second solution tank 12, with the speed of the PBS solution delivery being the seventh delivery speed.

In some examples, the seventh delivery rate may be a seventh delivery rate that may deliver 5 kilograms of PBS solution to the second solution tank 12 for 1 minute. Thus, the first solution tank pump 117 can deliver the PBS solution to the second solution tank 12 at a faster rate.

In some examples, when the measured difference between the amount of solution in the second solution tank 12 and the preset target weight of the second solution tank 12 formulation solution is the fifth difference, the control module 13 issues a command to the first solution tank pump 117, and the first solution tank pump 117 adjusts the conveyance speed at which the PBS solution of the first solution tank 11 is pumped and conveyed to the second solution tank 12 to the eighth conveyance speed. In some examples, the eighth delivery rate may be 1 minute to deliver 3 kg of PBS solution to the second solution tank 12. Thus, the first solution tank pump 117 can reduce the conveying speed of the PBS solution to the second solution tank 12, which is beneficial to controlling the amount of solution in the second solution tank 12.

In some examples, when the measured difference between the amount of solution in the second solution tank 12 and the preset target weight of the second solution tank 12 formulation solution is the fifth difference, the control module 13 may instruct the first solution tank pump 117 to stop pumping the PBS solution of the first solution tank by the first solution tank pump 117. The control module 13 sends a command to the first solution tank peristaltic pump 118, the first solution tank peristaltic pump 118 pumps the PBS solution of the first solution tank 11 to the second solution tank 12 for precise liquid adding, the pumping speed of the PBS solution is a ninth conveying speed, and the ninth conveying speed can be 3 minutes to convey 1 kg of PBS solution to the second solution tank 12. Thus, the first solution tank peristaltic pump is capable of delivering the PBS solution to the second solution tank 12 at a slow delivery rate, which is advantageous in controlling the amount of solution in the second solution tank 12.

In some examples, the control module 13 may also adjust a delivery rate of the PBS solution from the first solution tank 11 to the first solution tank 11 by the first solution tank peristaltic pump 118 according to a measured difference between an amount of the solution in the second solution tank 12 and a preset target weight of the solution formulated by the second solution tank 12, and the delivery rate may be a tenth delivery rate, an eleventh delivery rate, or a twelfth delivery rate. Thus, the control module 13 can slowly charge the second solution tank 12 by controlling the charging speed of the first peristaltic pump 118.

In some examples, the ninth conveying speed may be higher than the tenth conveying speed. The tenth conveying speed may be higher than the eleventh conveying speed. The eleventh conveying speed may be higher than the twelfth conveying speed. Thus, the first solution tank peristaltic pump 118 is capable of delivering the PBS solution to the second solution tank 12 at a slow delivery rate, which is advantageous in controlling the amount of solution in the second solution tank 12.

In some examples, when the measurement value of the solution second measurement module in the second solution tank 12 reaches a sixth predetermined value, the control module 13 may instruct the first solution tank peristaltic pump 118, and the first solution tank peristaltic pump 118 stops pumping the PBS solution in the first solution tank 11.

In some examples, the control module 13 may also instruct the second solution tank support 123 when the measured value of the solution second measuring module in the second solution tank 12 reaches a predetermined value, the second solution tank support 123 being provided with a second clamping mechanism 124, the second clamping mechanism clamping the second solution tank 12 away from the second weighing apparatus 121.

In some examples, step S160 instructs the second stirring device 125 to start stirring the glucose solution in the second solution tank 12 by the control module 13 after the second clamping mechanism 124 clamps the second solution tank 12 off the second weighing apparatus 121. In this case, stirring the glucose solution of the second solution tank 12 does not generate impact to the second weighing apparatus 121, and the second weighing apparatus 121 can maintain a good measurement state.

In some examples, step S170 may instruct the control module 13 to an analyzer inside the second solution tank 12 after the stirring of the glucose solution in the second solution tank 12 is completed, the analyzer will measure the concentration of the glucose solution of the target concentration in the second solution tank 12, and if the concentration measurement of the glucose solution of the target concentration is within the second predetermined range, the preparation of the glucose solution of the target concentration in the second solution tank 12 is completed.

In some examples, where the analyzer measures a measured value of the glucose solution at the target concentration in the second solution tank 12, if the measured value is higher than a second preset range of the target concentration, a certain amount of the PBS solution needs to be added to the second solution tank 12, and the control module 13 may calculate the amount of the PBS solution that needs to be added according to the measured value of the analyzer. The control module 13 may control the peristaltic pump 118 of the first solution tank to pump the PBS solution in the first solution tank 11 to the second solution tank 12, the second stirring device 125 may stir the glucose solution in the second solution tank 12 again, the analyzer measures the glucose solution with the target concentration in the second solution tank 12, and if the measured concentration value of the measured glucose solution is within the second preset range of the target concentration, the preparation of the glucose solution with the target concentration is completed.
