The Optimal Design And Implementation Of QCM Detecting System's Software

This thesis introduced a design of upper computer program used in a double-channel QCM (Quartz Crystal Microbalance) detecting system; this system use RS-232 standard serial communications interface to transmit data, on this basis, a number of practical optimization had been done. This program used in upper computer is developed in Visual C++6.0; the serial communication interface of upper computer is used to complete the task of transmitting the data from sampling board to upper computer. After the implement of a series of functions such as:data transfer and storage, data display, printing, some pivotal parts of this detecting system had been optimum designed again, including:data transfer module, display module, print module, etc. Finally, in order to resolve the ubiquitous non-linear problem of QCM sensors, a non-linear correcting module is added to the upper computer system.At the beginning of this thesis, the background of the task is introduced; on the other hand, the current stage and development of QCM detecting technology at home and abroad had been introduced too. Research purpose and significance of this item had been pointed out. Then, the theory of QCM sensor and its application field, this system's design ideas are all introduced. At last, the important modules are designed and optimized one after another. Comparing with previous upper computer program, the structure of optimized system is more reasonable, the operations on this program are more humanity. It laid the foundation for the commercialization of the detector.
