粮仓温湿度检测及控制系统的设计

Design of Granary Temperature and Humidity Measuring and Control System

提出一种用单片机采集数据,由计算机计算显示及控制的实用测温、测湿及通风控制系统。通过在元器件选型及软件设计上的精心考虑,以较低的成本实现了一个高精度、低功耗、布线简单、可扩展的粮情数据测量、控制系统。重点给出了该系统的硬件电路及软件电路部分。

This paper presents a kind of practical temperature and humidity measuring and ventilation control system,based on SCM collecting data and computer display and control.Through the selection of components and careful considerations of software design,a high precision,low power,simple topology and extensible grain detecting and controlling system is achieved with comparatively low costs.This paper mainly gives the hardware circuit and software design of the system.
