摘　　要：针对目前国产气象数据采集设备不多的状况,本文设计了一种基于USB的气象数据采集器,并且详细介绍了多通道温度、湿度以及大气压数据采集系统的结构设计和工作原理。该系统的微控制器采用MSP430F449单片机,对多通道的温度、湿度及大气压数据进行通道选择、数据采集、数据处理、液晶显示,同时还设计了基于USB(universal serial bus)技术的数据存储系统,极大地改善了数据传输速率和存储容量。Due to the insufficiency of domestically made meteorological data collecting device, We propose a kind of meteorological data collecting system based on USB （universal serial bus）. The working principle and system structure of meteorological data collecting system with multi-channel temperature, humidity and air pressure display are introduced. The system uses MSP430F149 as the controller to choose channels, collect, analyze and display data on LCD. A data storage system based USB technology was designed to save the meteorological data on memory medium, which greatly improve the transfer speed and storage capacity.
