| 摘 要： | 在数据传输速率要求不是很高的前提下,采用IIC总线的系统进行数据采样和传输是个很好的方案。将具有IIC接口的主、从器件,通过一根数据线和一根时钟线将不同地址的单通道模数转换芯片和数据传输芯片级联在一起,构建多点数据采集和传输系统,实现多通道模数转换芯片和数据传输芯片的功能。再配合扩展芯片的使用可以扩展总线的传输距离。通过对IIC总线典型的工作模式主发、主收的分析,该方法能满足绝大多数情况多点数据采集和传输的工作。

| Abstract: | When requirements for data transmission rate is not very high,using the IIC bus system for data sampling and transmission is a good choice.By concatenating the main device,slave devices with IIC interface together through a data line and a clock line,conversion chip and data transmission chip with different addresses and single channel analog-digital are connected.In this way,the multi point data acquisition and transmission system are constructed to achieve multi channel A/D conversion chip and chip data transmission function.With the expansion of the chip,the bus transmission distance is extended.The analysis of typical IIC bus operating mode of main sending and main receiving mode shows that this method can meet the demands of most cases in multi point data acquisition and transmission work. |
