摘要
为了提高温湿度传感器检定的效率,为气象业务的发展提供快捷的服务,设计了一种基于AVR单片机的多通道温湿度传感器检定系统。该系统硬件上采用AVR系列微控制器ATmega16和24位高精度A/D转换芯片ADS1232,实现了对温湿度传感器的数据信息采集;软件系统基于RS 232串口,利用数据库SQL Server 2000和VC技术,实现了温湿度传感器的自动检定。结果表明,系统大大提高了温湿度传感器的检定效率和准确度。
In order to improve the verification efficiency of temperature/humidity sensors and provide a quick service for the development of meteorological service, in hardware system, AVR MCU-ATMEGA16 and high-accuracy A/D conversion chip ADS1232 with 24 b are adopted to realize data information acquisition of temperature/humidity sensor; in software system, the automatic verification for temperature/humidity sensors is realized by using database SQL Server2000 and VC technology on the basis of RS 232 serial ports. This system significantly improves verification efficiency and accuracy of temperature/humidity sensors.
