基于LONWORKS技术的空调回风温度控制系统开发

Return Air Temperature Control System Development Based on LONWORKS Technology

文章针对某建筑空调系统控制需求,设计开发了基于LONWORKS技术的回风温度控制系统,采用Neuron3150芯片为核心芯片研制了数据采集和控制器节点,数据采集节点采用MAX186作为A/D转换芯片,控制节点采用MAX536作为D/A转换芯片,数据采集节点和控制节点I/O对象均选用Neurowire全双工串行操作方式。控制算法采用Neuron C编写,利用PI控制算法实现了空调区域回风温度控制。

According to the control demand of a building＇s air conditioning system, design and development of the control system based on LonWorks Technology of air temperature, the neuron chip 3150 chip as the core of the development of the data acquisition and control nodes, the node data collection by max186 as a / D conversion chip, the control node using MAX536 as D / a conversion chip, data acquisition node and control node i / O object are selected Neurowire full duplex serial mode of operation. The control algorithm uses Neuron control algorithm to achieve the C, air conditioning zone air temperature control using PI.
