When weighing, the cost price of the weighing appliance with the same precision is different by a plurality of times according to different weighing ranges. By adopting the invention, the required effect can be achieved by using a weighing device with a very small weighing range. For example, a weighing apparatus having a maximum weight of 3000g is normally required, whereas with the present invention only a weighing apparatus having a maximum weight of 300g is required.

the second obtaining module is used for obtaining a second weighing weight of the transfer container, wherein the second weighing weight is the weight of the transfer container after the auxiliary agent filling pump extracts auxiliary agent from the transfer container and fills the auxiliary agent into the target container;
the second calculation module is used for calculating the actual injection weight of the auxiliary agent according to the difference value of the first weighing weight and the second weighing weight;
the third calculation module is used for calculating the calibration weighing parameters according to the preset weighing parameters, the set calibration weight and the actual injection weight;
the fourth calculation module is used for calculating a second rotation amount of the filling pump according to the calibrated weighing parameters and the set filling weight of the next filling reagent;
and the second control module is used for controlling the rotation number of the auxiliary agent filling pump according to the second rotation quantity so that the auxiliary agent filling pump can extract auxiliary agent from the transfer container and fill the auxiliary agent into the target container.
6. The controller as set forth in claim 5, further comprising:
the judging module is used for judging whether the calibrated weighing parameter and the preset weighing parameter are in a preset deviation range or not;
if yes, carrying out the calibration weighing parameters obtained through calculation and the set filling weight of the next filling reagent, and calculating the second rotation quantity of the filling pump;
if not, returning to the process of calculating the first rotation amount of the auxiliary agent filling pump according to the preset weighing parameters and the set calibration weight.
7. An additive filling apparatus, comprising:
a transfer container;
the transfer container is placed on the weighing device;
