摘要
多路温度测量系统的信号处理单元采用飞利浦公司带有I2C总线的单片机P87LPC764,温度信号由DALLAS公司生产的带有I2C总线接口的数字式温度传感器DS1621采集后直接转换为数字信号通过串行数据(SDA)和串行时钟(SCL)二线传入单片机,通过单片机进行数据分析,整理后传输至带有I2C总线接口LED驱动控制器件显示被测温度值。
Single-chip computer (P87LPC764) with I^2Cbus interface produced by Philips Co.is used as signal processing unit in this system.After being sampled by digital temperature sensor DS1621 produced by DALLAS Co.,the signal of temperature is changed into digital signal and transmitted into single-chip computer by wires-SDA and SCL.Then digital signal is processed in single-chip computer and transmitted into LED in order to display the values of temperature.
