基于储存管理的气象监测仪的设计与实现

文中研究了一种基于储存管理的气象监测仪。系统硬件主要包括主控、存储、传感器和通信等四个模块。其测风系统通过由XW3200电子罗盘、叶轮式风速传感器等组成的磁风标传感器实现风的测量;测压电路采用ASDX015绝压传感器,获取模拟电压传入主芯片,并通过模拟-数字转换器转换为数字信号;在接收到数据处理系统命令后数据采集系统迅速开机,主芯片通过滤波处理接收到的各传感器采集数据并首先存入固定存储器,进而发送给数据处理系统,实现对空气温度、湿度、气压和风的测量。该监测仪可实现储存管理所需的气温、气压、湿度、风等数据采集与处理。测试结果表明,系统性能可靠、使用方便,能够满足储存管理的性能指标要求。
