Abstract

The invention discloses a system for monitoring and automatically regulating temperature in a solid fermentation process based on a singlechip. A water filler is arranged at the top of a fermentation tank; the fermentation tank is internally provided with a heat insulation board and a carrier disc; a temperature sensor is fixed on the carrier disc; the fermentation tank is connected with a refrigerator by a heat insulation pipe; a heater strip is arranged at an air inlet in the fermentation tank; a power fan is connected between the fermentation tank and the refrigerator in series; an air outlet is arranged between the power fan and the fermentation tank; the air inlet is arranged between the power fan and the refrigerator; a singlechip is connected with the temperature sensor by an A / D (analog / digital) converter; the singlechip is connected with a temperature control module by a D / A (digital / analog) converter; the temperature control module is connected with the heater strip and is connected with the refrigerator; the refrigerator is provided with a cold water inlet and a cold water outlet; the singlechip is connected with a liquid crystal display circuit and a keyboard by an 8155 expanded circuit; a data output port of the singlechip is connected with a buzzer; and the singlechip is connected with a PC (personal computer) upper computer by a serial passing circuit. Stability is good, and control accuracy is high.

Description

technical field [0001] The invention relates to the field of bioengineering equipment, in particular to a single-chip microcomputer-based temperature monitoring and automatic regulation system during solid fermentation. Background technique [0002] In recent years, the research on the control of fermentation process has become a research hotspot at home and abroad, mainly using advanced scientific and technological tools to solve the problems of parameter measurement and process optimization control in the biological fermentation process. It can be seen that the intelligent control method has become one of the most promising development directions of fermentation process control. However, at present, the control technology of my country's fermentation industry, especially the solid fermentation technology is still relatively backward compared to other industrial technologies, and the degree of automation is not high. The obtained data often adopts offline analysis mode, whi...
