Monitoring system of microbial fermentation process

Microbial fermentation process is a very important production link in the fermentation industry, the paper introduces the actual scheme of computer distribution control system (DCS), mainly discusses the system functionWith the rapid development of biotechnology industry, biofermentation technology and fermentation device as the basis of biotechnology industrialization, the control system in the process of microbial fermentation will be more and more finely perfected, and the problems in biofermentation automation will gradually disappearThis paper mainly introduces several environmental parameters of the environmental control system of microbial fermentation process and how to realize the automatic control of microbial fermentation through the computer distribution control systemthe monitoring system of the newly developed microbial fermentation process first, according to the principle and process of microbial fermentation, clear control parameters and control object model, innovatively put forward the index integral PID control and fuzzy PID control algorithm, and obtained good control effect in practical application, and the monitoring software design method of microbial fermentation process is developed with The Lab Windows/CVI development environment with flow chart display, real-time and historical trend chart display, historical data preservation, excel format report The monitoring software of complete functions such as industrial Ethernet communication, custom advanced algorithm interface, and finally, for the lack of using Rabbit2000 as an embedded network controller, the embedded all-in-one machine based on ARM9 advanced embedded microprocessor and embedded Linux was designed, and the MSP430 microcontroller was designed with a high-impact, isolated, can be applied to harsh industrial environment, and then used multiple data collectors through RS485The main-slave bus is connected to the embedded all-in-one machine, which makes the system more scalableindustrial control system is moving towards digitalization, intelligence, networking and opennessIndustrial production needs to be intelligent, digital transformation, automatic control, embedded technology and its products play a vital roleEmbedded systems are defined as: application-centric, computer-based, software hardware can be cropped, can adapt to the application system on the function, reliability, cost, volume, power consumption of strict requirements of the dedicated computer systemEmbedded applications have expanded from industry, communications, and networks to consumer areas related to digital multimedia, and their strong momentum validates the prediction of Niglo Ponti, the global advocate of the digital revolution, that embedded applications are the greatest application invention spent after pCs and the Internetthe system has designed a control structure with good development, dispersion, easy to expand and integrate with the help of the rapid development of embedded system technology in industrial controlAnd designed intuitive, friendly, easy to operate, compatible with other programs of monitoring software
