Application Of Wireless Communication Technology To The Microfluidic Preparation Of Photosynthetic Function Microstructure

With the progress of science and the improvement of informatization level,automation equipment is toward a more portable, miniaturization, networked and intelligent direction. The precise control of fluid flow in more and more areas is particularly important, such as: in the chemical industry, chemical elements for trace detection and analysis often require precise control of the flow; in the health care field,blood transfusions, anesthetic injections, antibiotics intake and painkiller injections all need precise flow control; and in biological engineering, medical injections, micro-fiber formation, cell encapsulation and etc. need the precise control of flow. And the requirement for the precision of injection pump which is essential for the biological experiment of micro-liquid sampling device is more and more high. In this thesis, by analyzing the working principle and design requirements of micro-liquid sampling device, the wireless control system was designed by using the intelligent mobile phone as the core of the control system. The system is not only suitable for routine biological liquid sample addition experiment, but also suitable for other occasions that require accurate flow control. The system was designed to provide an accurate and convenient quantitative add sample experimental samples.At the initial research stage, the author of this thesis made a lot of analysis for the micro injection pumps currently on market. On the basis of respective advantages and disadvantages, some improvement was made. At last, the wireless injection pump control system was successfully designed to adapt to the level of modern science and technology. The system design consists of two parts, including the hardware and software structure designs. In addition, the micro fibers were prepared on the wireless control system platform, and the experiment results were analyzed. On the premise of guarantee the expected experiment precision, the optimal design was achieved.First, in the hardware structure design of the system, the design was performed respectively from the chip selection, the system control program, the main control circuit, communication interface and etc. The system hardware structure and the function of each part were described in detail. At last, the whole hardware system of the wireless control system of micro injection pump was successfully designed.Secondly, in the software structure design of the system, the software development platform and the build process were briefly introduced. The control system designconcerns a software control total system and software control subsystems, including receiving and sending, communication instruction and protocol and Android application program development. Among them, the Android application development interface structure design, the function modules and command modes were introduced in detail.Finally, micro fibers were successfully prepared on the biological engineering technology platform. Here, the author briefly introduced the microfluidic focusing flow chip making technology. Specially, the reagent for micro fiber preparation, the experimental equipment and procedure were introduced in detail. The experimental results were analyzed after finishing the preparation. Finally, the designed wireless micro injection pump system was tested. The test results show that the designed system satisfies expected accuracy index, and thus it can meet the basic requirements of the micro injection and can be used in the fields of chemistry, medicine, bioengineering and etc. Especially, the designed system is expected to be widely used in some isolated operation occasions.
