控制温室大棚通风窗小技巧
通风窗对于制温室大棚就好比我们住房的窗户一样，是通风换气的最佳窗口，人类居住中可以随时更换窗户的开口大小，那么智能制温室大棚中通风窗是如何控制的呢？
智能制温室大棚采用智能控制系统，得到降温需求信号时，控制通风窗分级打开。系统以温度控制为第一优先权，在内外温差较大时，通风窗将开启较小的角度进行除湿，防止室温降低过快。冬季则在通风窗除湿时，随动收拢一小部分内保温幕，以使湿气能顺利从通风窗排除。而且你一定想不到的是，控制系统还具有智能保护功能。天窗电机为大传动比变速箱，并且拖动的负载也很大，当电机正在运转时，若接到反转信号，则齿轮极易咬坏。所以，控制系统接到反转指令后，将停转电机，并延时15秒，待惯性泄掉后，再反转。大风、雨雪时系统不是判断瞬间风速的超标，而是判断风整体趋势的变化，以进行大风时的关闭通风窗的保护。风向传感器能判断出是迎风还是背风，以进行不同级别的保护。微雾降温时，自动开启通风窗。微雾加湿时，自动关闭通风窗，以此来做到智能控制室内温度及湿度等的变化。
System of ventilation window for greenhouses is just like the Windows of our housing, is the best window ventilated take a breath, can change the opening size of the window at any time in human living, the intelligent system of ventilation in greenhouses is how to control?
Intelligent greenhouse to adopt intelligent control system, the cooling demand signal, control the ventilation window open classification. System with temperature control is the first priority, in internal and external temperature difference is bigger, ventilation window will open with a smaller Angle dehumidification, prevent room temperature decrease too fast. When winter ventilation dehumidification, follow-up tucked inside a small portion of the heat preservation act, in order to ensure a smooth moisture can be excluded from the ventilation window. And you would never guess that is, the control system also has the function of intelligent protection. Sunroof motor for big transmission ratio gearbox, and drag the load is big, when the motor is running, if received a reversal signal, the gears are bit bad. So, after been instructed inversion of control system, will halt the motor, and delay of 15 seconds, after being inertia drain off, then reverse. Wind, snow and rain when the system is not to judge instantaneous wind speed, but the whole trend of the wind of change, for the wind when closing the protection of the ventilation window. Can judge the windward or leeward wind sensor, for different levels of protection. Micro fog cooling, automatic open ventilation window. Micro fog humidification, automatically shut ventilation window, in order to achieve the intelligent control of indoor temperature and humidity changes.
