Description: 485收发+DS18B20呼叫应答方式(ATMEL89C2051)
温度是工业生产中重要的物理参数之一，对其进行测量与控制是一项非常传统的工艺技术。采用数字温度传感器DS18B20和AT89C2051单片机进行温度数据的采集和存储，通过RS485总线传输。上位计算机对所测得的每个误差补偿量，依据误差回归模型的最小二乘法进行参数估计。做出线性误差补偿模型的数学方程，对常温下测量的数据进行了补偿处理，在-55℃到+125℃测量范围和测量精度0.2级下，实现传输距离达到500 m，并根据工程实践给出提高传输距离与测量精度的关键技术。-485 to send and receive+ DS18B20 call response mode (ATMEL89C2051)
Temperature is one of important physical parameters in industrial production, its measurement and control is a very traditional technique.Using digital temperature sensor DS18B20 and AT89C2051 single-chip temperature data collection and storage, through the RS485 bus transmission.Measured by computer for each error compensation amount, according to the error of the regression model of least squares method for parameter estimation.Make the mathematical equations of linear error compensation model, processing of the measured data of temperature compensation, in- 55 ℃ to+ 125 ℃ measurement range and measurement accuracy under 0.2, realize the transmission distance of 500 m, according to the engineering practice gives the key to improve the transmission distance and accuracy of measurement technology.
