| The vibrating cylinder micro-mass sensor as a new sensor is widely used in chemical, biological, surface treatment and many other fields, there is broad application space. In order to deeply research the measurement of vibrating cylinder micro-mass sensor and expand its scope of application,we need to build a experiment analysis system.This paper research and design a analysis system, contain a vibrating cylinder micro-mass sensor, an embedded Linux system of S3C2410 IC core board and data acquisition card,.complete the system hardware, realize the transplant of Linux operating system and frequency counter, develop the human-machine interface, and verify the measure system and theory.First of all, analyze the working principle of vibrating cylinder; according to the relationship between micro-mass objects and the frequency of output signal of vibrating cylinder, design frequency meter and processing of the overall system. The pick-up signal of vibrating cylinder is sampled by data acquisition card , research the relationship between the signal change and the tiny quality.Secondly, study the core of linux, complete the verification and transplantation of vivi and Linux embedded system. Develop the corresponding device driver for hardware platform, accomplish the communication between hardware platform and software system.Then, aim at the characteristics of data acquisition card and the main functions; build a data sampling interface and menu with VC++ according to the human machine dialogue mode, complete data display, storage and other functions.Finally, complete experiment, through the data to analysis the relationship of micro-mass and signal change.The establishment and accomplishment of the analysis system provide other researchers a secondary development platform to improve and expand hardware and software work base on this system, thereby enhancing the efficiency of the researchers and reduce the cost of required equipment. |
