| 摘 要： | 自动化气象仪器要从模拟信号传感器获取数据,必须经A/D模数转换器接受传感器的低电平信号并输出数字。针对目前应用在自动气象站和检定设备的A/D模数转换器一般在12位或以下已不能够完全达到新气象仪器所需要求的情况,文章对在硬件电路开发设计中使用AD公司最近推出的24位串行模数转换器AD7714功能和特点进行了介绍,给出了基于AD7714实际应用的硬件、软件设计方法,以及部分程序源代码。总结出该芯片在实际应用中必须注意的几个技术问题,并介绍了实际应用情况。

| Abstract: | The A/D devices used in automatic weather stations and the authenticated devices are usually 12 bits or below,because the stability and accuracy of data conversion are determined by the bits of A/D devices,which cannot meet the needs of new meteorological equipment.Using the 24-bit serial A/D device,AD7714,produced by Analog Devices Company,is used in the design of the new circuits for the operational system.The functions and characteristics of AD7714,some of the source codes,and the AD7714-based design methods of software and hardware are introduced.Besides,some technical problems encountered in practical application are discussed. |
