符合CAN总线规范的热敏电阻传感节点设计

Design of thermistor sensor nodes conforming to the CAN bus specification

热敏电阻是具有测温准确、性能良好等优点,在测控领域被大量作为测量温度的传感器使用。本文讨论热敏电阻的特性及线性化方法,并以热敏电阻作为感温元件,设计一种符合CAN总线规范的热敏电阻传感节点,以利于实现温度的大规模智能化、分布式检测和控制。

Thermistor has advantages of high accuracy and good performance, which is used for temperature measurement widely in measure and control field. The characteristics and linearization method of thermistor are discussed in this paper, With thermistor as temperature sensing device, CANbus-based sensor node is designed in order to achieve large-scale, intelligent, and distributed temperature measurement and control.
