本文采用满足JJF1260-2010《婴儿培养箱校准规范》要求的单总线高精度温度传感器,并提出自适应数据位解码方法,不受时钟频率漂移等因素影响,相比于采用中断法或查询法读取温度数据具有更强的适应性。本系统5个温度点校准均采用无线方式,仪器尺寸较小,操作简便,可更好地服务于现场校准工作,提高工作效率。
In this paper, to meet the JJF1260-2010 “incubator calibration standards,” a single-bus high-precision temperature sensor, and proposed adaptive data bit decoding method, free from clock frequency drift and other factors, compared to the interrupt method or query method Take temperature data has more adaptability. The system temperature calibration of five points are used wireless way, the instrument size is small, easy to operate, can better serve the on-site calibration work, improve work efficiency.
