Embodiment Construction

[0084] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0085] The rapid weighing method of the present embodiment loose bag small package Chinese medicine, comprises steps:

[0086] 1) Establish an equivalent physical model of the weighing system for bulk bags and small packages:

[0087]

[0088] Among them, m is the equivalent mass of the drug receiving tank; M is the mass of the drug package to be weighed; y(t) is the output signal of the weighing system; g is the acceleration of gravity; c is the equivalent damping coefficient of the weighing system ; k is the equivalent elastic coefficient of the weighing system; when the loose bag and small package of traditional Chinese medicine falls on the medicine receiving tank, the medicine bag will vibrate synchronously with the weighing system represented by the medicine receiving tank, which can be regarded as the weighing system A step signal Mgu(t) is a...

Abstract

The invention discloses a method for quickly weighing bulk small-package traditional Chinese medicines. The method comprises the steps of: 1) establishing an equivalent physical model of a bulk small-package weighing system, and obtaining a calculation formula of the mass M of a medicine package to be weighed through Laplace transformation and Z transformation; 2) calculating a1, a2, b1 and b2 based on the vector prediction error; and 3) according to the obtained a1, a2, b1 and b2 and the calculation formula of the mass of the to-be-weighed medicine bag, obtaining the weight of the weighed bulk-bag small-package traditional Chinese medicine. According to the method for quickly weighing bulk small-package traditional Chinese medicines, scalar prediction errors are expanded into vector prediction errors on the basis of a traditional method, a new identification model based on the vector prediction errors is constructed, the utilization efficiency of the prediction error is higher, and itcan be known through an actual weighing comparison test that compared with a traditional weighing method, the weighing method provided by the invention is higher in convergence speed and higher in parameter identification precision, the weighing time can be shortened, and the weighing efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of automatic medicine cabinets, in particular to a method for weighing traditional Chinese medicine in loose bags and small packages. Background technique [0002] Traditional Chinese medicine has a long history in our country and is one of the three national quintessences of our country. As the precious wealth of the motherland's medicine, Chinese medicine has always been welcomed by the majority of patients. With the development of the times and the continuous progress of science and technology, traditional Chinese herbal decoction pieces are being transformed into new modern Chinese herbal decoction pieces, and small-package Chinese herbal decoction pieces have emerged as the times require. Small-package traditional Chinese medicine has many advantages such as maintaining properties, accurate dosage, easy review, clean and hygienic, convenient dispensing, and improving efficiency. [0003] In the prior a...
