Pump quantity calibration method of peristaltic pump, controller and control system

The embodiment of the invention relates to a peristaltic pump, and discloses a pump quantity calibration method of the peristaltic pump, a controller and a control system.The method is applied to the control system of the peristaltic pump, the control system comprises a storage pool, a standard pump, a to-be-calibrated pump and a driving device, the standard pump and the to-be-calibrated pump are both connected with the storage pool, and the standard pump quantity of the standard pump is obtained; controlling the to-be-calibrated pump to pump the to-be-measured liquid into the storage pool, determining a first parameter corresponding to the to-be-measured liquid pumped into the storage pool, controlling the standard pump to pump out the to-be-measured liquid in the storage pool, determining a second parameter of the displacement sensor corresponding to the to-be-measured liquid, and determining the pump volume of the to-be-calibrated pump according to the standard pump volume, the first parameter and the seco
