Embodiment Construction

[0041]In order to comply with the strong development trend of transdermal drug delivery systems (TDDS), the present invention discloses an automatic control system for cataplasm coating based on FPGA fuzzy pattern recognition. The system is equipped with a CCD camera and a video A / D converter at the front end, which provides reliable analysis input data for the realization of the whole system. Embed the theory of fuzzy pattern recognition into the system, analyze, process and recognize the digital video stream converted by the video A / D converter through online detection, and finally successfully feed back and output the automatic control signal. This system adopts the EP2C35 FPGA chip based on Cyclone II series, and uses the Verilog HDL hardware description language to realize the closed-loop system of on-line detection of cataplasms and automatic control of coating.

[0042] The present invention will be further described in detail below in conjunction with the accompanying ...

Abstract

The invention relates to the fields of computer technology, automatic control technology and drug coating. In order to realize full automation of the process of controlling and detecting the cataplasm coating uniformity and thickness, improve the practicability and reliability of a system, lower the blindness in the production process and enhance the product quality, the invention adopts the technical scheme that an automatic cataplasm coating control system based on FPGA (field programmable gate array) fuzzy pattern recognition comprises a camera CCD (charge coupled device), a high capacity cache SDRAM (synchronous dynamic random access memory) which is taken as an external cache to store a digital video image signal and a programmable logic device FPGA, wherein the interior of the FPGA is provided with an SDRAM controller, a pattern recognition module comprises a division auxiliary functional module and is used for judging and recognizing a signal by applying the fuzzy pattern recognition principle and providing a control feedback signal, and the interior of the FPGA is also provided with a configuration initialization module used for initialization configuration on a video decoder. The invention is mainly applied to drug coating.

Description

technical field [0001] The present invention relates to computer technology, automatic control technology and medicament coating, in particular to an automatic control system for cataplasm coating based on FPGA fuzzy pattern recognition. Background technique [0002] In recent years, the transdermal drug delivery system has attracted the attention of domestic and foreign medical research institutions and pharmaceutical companies for its unique and effective disease treatment methods. In view of the broad market demand and application prospects of the TDDS system at home and abroad and its The unique therapeutic effect in the field has pushed the pharmaceutical molding process of cataplasms to automation and formed an unstoppable trend of industrial intelligence. The proposal of the research on the automatic control of cataplasm coating belongs to an important research link of the new drug creation project of the new transdermal drug delivery system of traditional Chinese med...
