  • Patent number: 11635324
    Abstract: The present disclosure discloses a method for quick weighing of loose and small packages of traditional Chinese medicine (TCM), comprising: 1) establishing an equivalent physical model of a weighing system for loose and small packages, and, through Laplace transformation and Z transformation, obtaining a formula of the mass M of medicine packages to be weighed; 2) calculating a1, a2, b1 and b2 on the basis of a vector prediction error; 3) according to a1, a2, b1, and b2 obtained and the formula of the mass of medicine packages to be weighed, obtaining the mass of the loose and small packages of TCM that are weighed. According to the method, the scalar prediction error is expanded into the vector prediction error based on the traditional method so as to construct a new identification model based on the vector prediction error, and as a result the utilization efficiency of prediction error turns higher.

  • Publication number: 20210008732
    Abstract: The present disclosure discloses an automated dispensing machine adopting local coverage type sucker array and a control method thereof. The automated dispensing machine adopting local coverage type sucker array comprises a rack. A medicine obtaining device and a medicine weighing and discharging device are arranged on the rack. The control method comprises: (1), after receiving medicine grasping and discharging commands, a single-chip microprocessor firstly selects a current medicine obtaining station according to a medicine obtaining station circulation sequence, and then controls the first linear driver to push the slide to move forwards to the selected medicine obtaining station; (2), the single-chip microprocessor transmits the control signal to a fifth relay to control the second linear driver to drive the vacuum medicine sucking mechanical arm to move downwards.
