| 摘 要： | 提出了一种基于混沌电路的温度测量新方法,与已有的测量方案相比,具有更好的线性度和更小的误差,它对测量电路参数要求不高,电路结构简单,电路中没有影响测量稳定性和产生零点漂移的元器件,大幅度地降低了测量过程中的噪声。此外,电路直接输出反映温度变化的二进制代码,便于计算机处理。测温精度优于±0.1℃,分辨力约为0.01℃,实验结果表明了该方法的优越性。

| Abstract: | A new method of temperature measurement based on chaotic circuits is presented.The new chaotic measurement system has better linearity and less error than present temperature measurement system,it is still very available when some components are low precise in measurement circuit,and the circuit structure is simple,the noise are also reduced greatly because of no any amplifier.In addition,the output signal varing with temperature has been digitized for further processing by the computer.Its error is less than ±0.1℃,and its resolution is 0.01℃. The experiment results show that the new method has very good advantage. |
