Abstract:
The principle of vibrating wire transducer is that the internal steel string＇s excited frequency has a corresponding relation with its force size，so the force size can be recognized by monitoring its excited frequency． With microcontroller as the core，this paper realized the function of vibrating wire transducer automatic recognition and multi-machine cycle measurement based on the series number of digital temperature chip DS18B20，achieved temperature measuring and nonlinear compensation by software programming，enhanced the measuring accuracy by equal-accuracy frequency measurement，created the conditions of further date analysis by adding time clock． This instrument has a practical value and a good market prospect for its advanced technology．
