摘  要
 对于仓库的监测系统，温湿度环境条件是重要的，但温湿度也是最不易保障的指标，针对这一情况，研制可靠且使用的温湿度控制器显得非常重要。本文介绍了环境温湿度实时测控装置的研制思路和方法。该温湿度实时控制装置可在-30℃--+50℃和10%--100%RH（相对湿度）的范围内任意设定温湿度值，可实现环境温度、湿度的实时测量，并附有通信接口可方便地实现与计算机的实时通信，而且便于功能的扩展，可保证温度、湿度满足设计指标，能方便地应用于仓库的监测系统。本系统是通过由单片机控制的LED显示器和键盘部分，外部存储器及其外设接口组成的，微机的主要任务是完成数据采集对数据进行处理，数据存储的逻辑判断，以及管理显示器和键盘来实现人机对话。

Abstract
    Monitoring system for the warehouse storage, environmental conditions of the temperature and humidity is important, but the temperature and humidity is the most difficult targets to protect against this situation, the development and use of reliable temperature and humidity control is very important. This paper introduces the environmental temperature and humidity in the development of real-time monitoring and control devices and methods of thinking. The real-time temperature and humidity control devices in -30 ℃ - +50 ℃ and 10% - 100% RH (relative humidity) within the scope of arbitrary values of temperature and humidity, can be the ambient temperature and humidity measurement and control of real-time and A communication interface can be easily achieved with the computer's real-time communication, and facilitate the expansion of functions, we can make sure the temperature and humidity to meet the design specifications, the warehouse can be easily applied to the monitoring system. The system is controlled by single-chip LED display and keyboard of the external memory and peripheral interface components and computer's main task is to complete data collection of data processing, data storage logic to determine, as well as management monitors and keyboard to achieve the man-machine dialogue.
