Research And Development Of Water-kevel Measurement Based Vibrating Wire Sensor

By reaserching the principle of vibrating wire sensor and its realization, The paper is designed intelligent water-level meter based vibrting wire senor , it is mainly composed with the system for the slave device and the inspection software running on the PC, The level data are real-time acquired displayed. At the same time , the measured data can be transmitted to the the PC and can be processed and printed Firstly , the paper is studied the principle of vibrating wire sensor, then designs the system hadeware and software according to its principle It is used to excite vibrating wire sesor using technology of hardware sweeping frequency it is used to equally accurate measuring frequency Considered the effect of water-level data of temperature, ICL7135 A/D converter is used to measure the temperture, to realize compensatation of temperature Based on the hardware, we have finished sofiware in the slave device and supervision software on the master PC Finally, Both hardware and software of the whole system have been optimized to make the system have excellent interference-immunity...
