Remote monitoring system for bioreactor

Abstract

The invention discloses a remote monitoring system for a bioreactor. The system comprises a bottom level monitoring sub system, a PLC programmable controller and a control client, wherein the bottom level monitoring sub system is arranged on the bioreactor and is used for monitoring a real-time reaction signal of the bioreactor, the PLC programmable controller is connected with the bottom level monitoring sub system, the reaction signal acquired in real time is transmitted by the bottom level monitoring sub system to the PLC programmable controller, the acquired reaction parameter signal is transmitted by the PLC programmable controller to an industrial control computer, the reaction parameter signal from the PLC programmable controller is processed and converted by the industrial control computer, the processed parameter data is sent to a network end, the control client can enter a browse page or is equipped with a monitoring APP, and various parameters of the bioreactor can be checked by a user through a browser or the APP of the control client. The system is convenient to use, requires no field monitoring and no filed operation carried out by a monitor and saves the time for an operator.

Description

technical field [0001] The invention relates to the field of biological reaction monitoring systems, in particular to the monitoring of values ​​such as pH, DO, temperature, stirring speed, pressure, weight, gas flow, and pump speed, and in particular to a remote monitoring system for bioreactors. Background technique [0002] At present, the commonly used bioreactor control system mainly relies on the PLC module and the on-site touch screen to realize the monitoring function. The monitoring personnel can view and control the parameters of the bioreactor through the manipulation of the touch screen man-machine interface. [0003] Because the bioreactor needs to run continuously for 24 hours for many days, and has relatively high requirements for the accuracy and stability of the control parameters, it is often necessary for the operator to go to the site to check whether the data is normal at regular intervals; or because of the needs of the cultivation process , It may be n...

Problems solved by technology

[0003] Because the bioreactor needs to run continuously for 24 hours for many days, and has relatively high requirements for the accuracy and stability of the control parameters, it is often necessary for the operator to go to the site to check whether the data is normal at regular intervals; or because of the needs of the cultivation process , it may be necessary to change a certain culture parameter at a certain time, for example, the temperature control needs to be changed from 36.8°C to 33°C at 11 o'clock in the evening; this monitoring mode is extremely inconvenient and increases the workload of monitoring operators

Moreover, the bioreactor is often placed in a clean area. In order to check whether the data is normal or to make some relatively simple parameter changes, the operator needs to spend a long time for sterilization before entering the reaction area, and sometimes even delays for an hour or two. , which is very inconvenient, and the frequent entry of operators into the reactor placement area also increases the risk of contamination
