Monitoring system and dynamic principal component analysis method of medicinal hopper cleaning machine

Abstract

The invention discloses a monitoring system for a medicinal hopper cleaning machine. A cleaning machine body is included, and internally provided with a cleaning cavity, a water inlet pipe is fixedly arranged at the upper end of the cleaning cavity, a water outlet pipe is fixedly arranged at the lower end of the cleaning cavity, the water inlet pipe is fixedly provided with a water inlet valve, a flow meter and a water pressure sensor, the cleaning cavity is internally provided with a first thermometer positioned at the water inlet of the water inlet pipe and a second thermometer positioned at the water inlet of the water outlet pipe, the water outlet pipe is fixedly provided with a water outlet valve, an A / D conversion module and a computer are arranged at one end of the cleaning machine body, the water pressure sensor transmits monitoring data to the A / D conversion module in a wireless or bus manner, the A / D conversion module converts analog data into digital data and updates the digital data to the computer, and the computer carries out dynamic principle component analysis on the data. According to the technical scheme, the structural design is reasonable, the structure is simple, work is reliable, use is convenient and the cleaning system operates stably.

Description

technical field [0001] The invention relates to the technical field of a medicinal hopper cleaning machine, in particular to a monitoring system and a dynamic principal component analysis method for a medicinal hopper cleaning machine. Background technique [0002] In the production of solid preparations, it is often inseparable from the processes of mixing, feeding and transfer, and utensil cleaning. However, the most prominent problem in the production of most solid preparations in my country is the cleaning of utensils. The purpose of equipment cleaning validation is defined from the "Guidelines for Pharmaceutical Production Validation (2003)", "The purpose of equipment cleaning validation is to prove through testing that the automatic cleaning procedure or manual cleaning procedure of the equipment can remove active drug residues on equipment parts , and meet acceptable qualification standards, and prove the stability and repeatability of this cleaning procedure." It req...

AI Technical Summary

Problems solved by technology

At present, domestic tools are still still cleaned by hand. Obviously, the manual cleaning process cannot make reliable and detailed records of the above parameters of each barrel!

[0003] Although the existing single-chamber and double-chamber hopper cleaning machines get rid of the manual cleaning method and adopt the automatic intelligent cleaning method, the manufacturer pays more attention to the cleaning effect rather than the operation status of the cleaning system

Obviously, the cleaning system and the cleaning effect of the hopper are interrelated, and the unstable operation of the former will inevitably affect the final cleaning effect
