【摘要】 随着农业生产的飞速发展,大规模的窖储白菜已出现在农村的生产中。降低白菜在窖内的损耗率已成为实际农业生产生活的重要问题。由于PLC具有可靠性高、便于扩展等特点,已逐渐代替了传统继电器控制的方式,检测技术和PLC应用于白菜窖储系统可实现该系统的功能要求。为此,介绍了检测技术和PLC在白菜窖储控制系统中的作用与功能的实现。更多还原

【Abstract】 With the rapid development of agriculture,a large scale storage of Chinese cabbage has appeared. Decreasing the huge loss of Chinese cabbage has been an important problem in agriculture. With the detection has been widely used,it’s measuring precision carried on a new and higher level. Since PLC has characteristics such as reliability and easy expansion,it replace relay that in old days. They can combine very well in some sides such as transmission caculation. Decetion and PLC can achieve the function of Chinese cabbage storage system. We therefore introduce detection and PLC system for use in the Chinese cabbage storage system.更多还原
