利用夜间低温时机开启仓窗适时通风,降低粮温效果明显,但在这个时段,人工开窗通风显然不太现实,且劳动量大。如何在减轻劳动量的情况下,及时抓住合理通风时机进行有效通风降温,是目前亟待解决的问题。应用电力线载波技术,开发应用计算机自动控制高大平房仓窗户和通风系统,在能 The use of nighttime low temperature opens the warehouse window timely ventilation, reduce grain temperature effect is obvious, but at this time, artificial window ventilation is obviously not realistic, and a large amount of labor. How to effectively ventilate and cool down when it is time to seize a reasonable period of ventilation while reducing the amount of labor is a pressing issue to be solved. Application of power line carrier technology, development and application of computer automatic control of high-level warehouse windows and ventilation systems, energy
