The invention discloses an intelligent control method and system for a micro-boiling state of traditional Chinese medicine extraction equipment without volatile oil. The traditional Chinese medicine extraction equipment is provided with a plurality of different heating nodes; each heating node correspondingly controls heating within a volume range through a respective heating jacket; the average temperature of fluid within each volume range is obtained through temperature measurement; for each heating node, the average temperature of the fluid is input into a fuzzy control model, a temperaturedifference value between the average temperature of the fluid and an expected target temperature is obtained, and the temperature rise time for heating to the expected target temperature from the current temperature under the current temperature condition is deduced; when the temperature rise time is greater than a threshold value, heating is controlled by a PID controller; and when the temperature rise time is smaller than the threshold value, heating is controlled by the fuzzy controller. According to the intelligent control method and system, automatic and accurate temperature measurementis achieved for different types of traditional Chinese medicines through a fuzzy PID control method, the steam pressure is controlled to achieve control over the micro-boiling state, the extraction efficiency of the traditional Chinese medicines is effectively improved, and the related requirements of medicine production are met.
Description
technical field [0001] The invention belongs to the field of traditional Chinese medicine pharmacy, and in particular relates to an intelligent control method and system for the micro-boiling state of traditional Chinese medicine extraction equipment without volatile oil. Background technique [0002] The product quality of Chinese patent medicine is related to the health of patients, and it is also the lifeline for the development and growth of pharmaceutical manufacturers. The extraction process of Chinese medicine is the core production process of Chinese medicine production process. This process requires heating to slight boiling for extraction, but insufficient heating steam pressure will cause If the micro-boiling state cannot be reached, the excessive steam pressure will cause the temperature to be too high to cause bumping and affect the properties of the internal substances of the traditional Chinese medicine. Therefore, the control of the boiling state is very impor...
