摘要
利用嵌入式高性能ARM7TDMI核微控制器芯片LPC2132进行红外测温仪的研制,给出了硬件设计的原理框图。详细阐述了信号放大、带通滤波器和检波部分的硬件设计,并进行了软件设计。由于LPC2132芯片内部集成了多种功能,简化了硬件结构。该红外测温仪具有配置简单,扩展方便,可靠性高的特点。
A method of developing infrared thermometer based on embedded and high performance ARMTTDMI micro-controller LPC2132 is introduced in this paper. The hardware circuit of amplifier, band-pass filter and demodulation is presented, and the related software is designed. Since the LPC2132 microcontroller is highly integrated, the hardware structure of the infrared thermometer is simplified. It is simple in configuration, convenient to extend and outstandingly reliable.
