高层建筑主通风机依靠通风动力,将定量的新鲜空气,沿着既定的通风路线不断地输入建筑内,以满足各通风地点的需要,同时将用过的污浊空气不断地排出地面。本文通过研究风机的运行和控制规律,开发出一种基于以太网的无人值守风机自动控制系统,并已在现场得到了成功的应用。1无人值守自动控制系统的构架无人值守自动控制系统是基于以太网的大型实时监控系统,由以下的结构图可以看出,本系统主要由五大 The high-rise main ventilator, which relies on the motive power of ventilation, constantly feeds a fixed amount of fresh air into the building along established ventilation routes to meet the needs of the ventilation sites while continuously discharging used dirty air out of the ground. In this paper, by studying the operation and control law of fan, an automatic control system of unmanned fan based on Ethernet has been developed and has been successfully applied in the field. A unattended automatic control system architecture Unattended automatic control system is based on Ethernet, a large real-time monitoring system, the following structure can be seen, the system consists of five
