摘要
针对传统温度检测系统中存在的温测上限低、功耗大、传输速率低等问题,采用新型薄膜铂温度传感器设计了一种基于GPRS的多点无线实时温度检测系统,并使用正反馈型线性校正电路进一步提高了系统的测量准确度。多次测试结果表明,该系统具有高度的准确性、灵敏性和实用性。
In this paper, a multipoint wireless real time temperature detection system was designed based on GPRS and film platinum temperature sensor, which adopted linear rectification circuit with positive feedback to enhance the accuracy of measurement. The testing results showed that this system had high accuracy, sensitivity and practicability.
