Embodiment Construction

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

[0085] The rapid weighing method of the traditional Chinese medicine in the small package of the bulk bag of the present embodiment includes the 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 medicine receiving tank; M is the mass of the medicine bag 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 traditional Chinese medicine in the small package of the loose bag 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 ...

Abstract

The invention discloses a fast weighing method for traditional Chinese medicines in small packages in bulk bags, which comprises the steps of: 1) establishing an equivalent physical model of a weighing system in small packages in bulk bags, and obtaining the to-be-weighed model through Laplace transformation and Z transformation Calculation formula for the quality M of the medicine package; 2) Calculate a based on the vector prediction error 1 , a 2 , b 1 , b 2 ; 3) According to the obtained a 1 , a 2 , b 1 and b 2 And the calculation formula of the mass of the medicine package to be weighed to obtain the weight of the Chinese medicine in the small package of the loose bag to be weighed. The rapid weighing method for traditional Chinese medicine in small packages in bulk bags of the present invention expands the scalar prediction error into the vector prediction error on the basis of the traditional method, constructs a new identification model based on the vector prediction error, and has better utilization efficiency of the prediction error. Compared with the traditional weighing method, the weighing method of the present invention has faster convergence speed, higher parameter identification accuracy, can shorten the weighing time and improve the weighing efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic medicine cabinets, in particular to a weighing method of traditional Chinese medicines in small packages in bulk bags. Background technique [0002] Traditional Chinese medicine has a long history in my country and is one of the three national quintessences of our country. As a valuable asset of the motherland's medicine, traditional 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, the traditional Chinese herbal medicines have been transformed into new modern Chinese herbal medicines, and small-package Chinese herbal medicines have emerged as the times require. Small package of traditional Chinese medicine has many advantages such as maintaining properties, accurate dosage, easy to review, clean and hygienic, convenient for dispensing, and improving efficiency. [0003] In the prior ar...
