摘要
本文研究了基于奈奎斯特定理"过采样和抽取"原理与采用"曲线拟合"方式的温度计算方法,根据空调控制精度的要求,提出相应解决方案。具体的内容包括以下几个部分:①控制器温度控制和计算方面采用奈奎斯特定理"过采样和抽取"的原理,通过大量的采集信号以提高MCU中温度AD采样的精度。②温度换算采用"曲线拟合"的方式,来实现对温度的精确计算和控制。
In this paper, the principle of " oversampling and extraction" based on Nyquist's theorem and the temperature calculation method using " curve fitting" method are studied. According to the requirements of air conditioning control accuracy, the corresponding solutions are proposed. The specific content includes the following parts: ① The controller temperature control and calculation method adopt the principle of Nyquist's theorem"oversampling and decimation", and improves the accuracy of temperature AD sampling in the MCU through a large number of acquisition signals. ② Temperature conversion adopts the method of " curve fitting" to realize accurate calculation and control of temperature.
