摘　　要：介绍了以MSC1210 Y5为核心的数据采集器作为下位机,PC机作为上位机构成气象数据采集系统的设计方法及工作原理。该系统通过模拟多路开关和数字端口对气温、湿度、气压等传感器输出的模拟信号以及雨量、风向和风速传感器输出的数字信号进行数据采集与处理。系统具有结构简单、精度高和功耗低等优点。通过串行接口与PC上位机通信,实现数据的再处理及转存管理。The design method and work principle of a data-acquisition system applying MSC1210 Y5 as slave processor and PC as host computer was introduced. The analog signals such as temperature, humidity, pressure were selected by the MUX, and the digital signals such as rain, wind direction, wind speed are dealt with the digital interface. The system has the advantages of simple structure, high precision,low power dissipation. The weather data can transmitted to the host by serial interface for further processing and storage.
