基于单片机的风杯防冻仪的设计

Design of Antifreezing instrument for Wind-sensor Based on Microcomputer

针对地面自动气象站风传感器在冬天经常被冻死这一现象,设计了温控风杯防冻仪。本文介绍了该仪器的工作原理,并着重讨论了系统硬件和软件实现方法。系统采用AT89S52单片机为核心,配置以温度传感器、A/D转换器等部件,实现了当环境温度低于温控阈值时对风传感器自动加热的功能。

Antifreezing instrument for wind-sensor is designed aimed at the phenomena that wind-sensor cannot move sometimes in winter. The principles and methods of the instrument based on AT89S52 applied for the wind-sensor are introduced in this paper and described the realizing approaches of both the hardware and soft ware in particularly. The AT89S52 single chip microcomputer is used as the kernel component of this system and the other parts are temperature sensor and analog-digital converter , which enable the controlling of the delay when the temperature is different.
