| ::软件简介:: |
| BioStat和BioFlo发酵罐控制程序,主程序用来收集发酵工艺数据、并采用模糊控制原理控制工艺参数。客户端程序可以使远程操作成为可能。甚至原理上可以从世界上任何一台联网计算机对发酵进行控制。 The Fermentor Control Program was made to facilitate and automate some general and time-consuming tasks. Initially, the program was made to collect the process data during fermentation and save these for further evaluation in other programs. Soon however, there was also a need for a more user friendly program compared to the on-board fermentor control, and the possibility of a TCP/IP client connection that significantly reduced the on-site time, a factor not to be underestimated in a research laboratory. These goals merged to the development of the current program. Basic Features The Fermentor Control Program (host) collects process data and display them in a graphical window with scrollable graphs and selectable views. These graphs can be printed during the run. All setpoints are controlled by graphical sliders or by keyboard, and numerical displays show the current settings. When a fermentation run is started, batch data such as date and time is registered and total fermentation time is recorded, and further customised batch data can be entered. Via the Fermentor Control Program profiles can be set for the batch to follow. Using the elapsed fermentation time as cue, all setpoints can be changed. Thus, substrate feeding and induction schemes can be given. All this requires no programming skills. Advanced Features A simple pH-Stat model for substarte feeding has been implemented. More intelligent control to master substrate addition is possible with the fuzzy logic control module and the neural network software sensor. Fuzzy logic control is equivalent to having computers reason like humans do, just much faster. Fuzzy logic is a way of letting the computer say little, not so big, big, bigger, and so forth, and base an output upon these vague inputs. Often biological systems are non-linear, difficult, or impossible to model mathematically. However, fuzzy logic is empirically-based and model free, thus it opens doors for the control of systems that normally would be deemed unfeasible for automation. The control module uses pO2, DpO2, and substrate setpoint and concentration as parameters for driving the substrate addition level. To view the fuzzy logic module at work go here. Neural networks can efficiently be used to forecast process values in fermentation processes, since they are able to map/describe non-linear functions. In the case of fermentation processes, neural nets are for instance able to forecast the substrate concentration on the basis of inputs such as culture volume, pH, pO2, and current substrate feed rate. Neural networks are used in large scale fermentation systems to aid the supervisor in keeping the batch in good shape thus maximising the product output. Since this is also the main goal in the research laboratories, a neural network software sensor module has been incorporated in to the Fermentor Control Program. Internet Features A TCP/IP client makes it possible to control the unit from any online computer in the world. The Remote Control Program is essentially the same as the host but receives data via the TCP/IP connection from the host control program. For safety, on the host the remote IP number can be specified or set to allow any connection via the client program. For windows 95 and 98 you may need to download and install DCOM95 or DCOM98 in order to install the Fermentor Control Program. |
