摘要:
弦振传感器的工作原理是传感器内部钢弦的弦振频率与其受力大小存在一一对应关系,通过监测其受到激振时的弦振频率就可以监测其受力大小.以新型微控制器为核心,利用数字温度芯片DS18B20的唯一系列号,实现了弦振传感器自动识别和多机循环测量功能;通过软件编程实现了温度测量和非线性补偿;基于等精度测频原理,提高了测量精度;通过增加时钟功能,为进一步数据分析创造了条件.该设备技术先进,具有较好的实用价值和市场前景.
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．
