【摘要】 为了精确地测量与调节果库的温度和湿度、利用自然冷源、提高果库的管理质量,对其温度与湿度调控系统进行了智能化调控设计。在主控单元中,采用了MCS-51系列的8031单片机,应用汇编语言,在温度的测量单元中,应用集成电路传感器,多通道巡检、采样,经主控单元处理,使测温误差控制在±0．2℃以内,在湿度测量单元中,应用电容式湿度传感器,并进行串联改造,使其在100％的相对湿度中保持良好的线性度。在执行机构中,采用了继电保护,对系统的工作过程实行了数字显示、打印记录。更多还原

【Abstract】 In order to measure and adjust the temperature and humidity accurately, the aptitude control system of experiment and design was made by using nature cold source, which can advance the control effect of fruit storage. The temperature and humidity of fruit storage were controlled by using assemble language with the 8031 type singlechip of series MCS-51. The error range of temperature was controlled in 0.4℃, and the linearity of humidity kept in 100%, The process was displayed with figure code and printed.更多还原
