Adaptive HVAC Automatic Control System Based on Raspberry Pi

在目前的暖通空调控制系统中,通常需要人工调整设定温度,缺乏自适应的自动控制。因此设计一种基于树莓派的自适应暖通空气自动控制系统。在系统的硬件设计中,选用树莓派3B微控制器为系统主控制器,并将SDRAM外部总线线路与主控制器连接,同时使用PT100热电阻温度检测器来收集控制数据。在软件设计上,通过C/S通信架构来进行数据传输,利用神经网络PID算法对树莓派3B微控制器进行自适应学习,从而实现自适应暖通空调的自动控制。为了验证设计系统的可行性,利用设计系统对某医院暖通空调进行控制,并测试控制性能以及抗干扰能力,实验结果显示,本文设计的自动控制系统,可以实现暖通空调的自动控制,且抗干扰能力较强,具有可行性。

In the current HVAC control system,it is usually necessary to manually adjust the set temperature,which lacks adaptive automatic control.Therefore,an adaptive HVAC automatic control system based on Raspberry Pi is designed.In the hardware design of the system,the Raspberry Pi 3B microcontroller is selected as the main controller of the system,and the SDRAM external bus line is connected to the main controller,and a PT100 thermal resistance temperature detector is used to collect control data.In software design,data transmission is carried out through the C/S communication architecture,and the neural network PID algorithm is used to adaptively learn the Raspberry Pi 3B microcontroller,so as to realize the automatic control of adaptive HVAC.In order to verify the feasibility of the design system,the design system is used to control the HVAC in a building,and the control performance and anti-interference ability are tested.The experimental results show that the designed automatic control system can realize the automatic control of HVAC,and the anti-interference ability is strong and feasible.
