基于单片机的仓库温湿度智能测控系统的设计与实现.doc

摘 要

摘 要

随着科技的飞速发展和普及，高性能设备越来越多，各行各业对温湿度的要

求也越来越高。为解决传统温湿度检测以往主要以人为基础、依靠人工轮流值班，

人工巡回查看等方式来测量和记录环境状况信息的模式，避免许多由人为因素造

成的重大事故，解决效率低下不利于人才充分利用的问题，让测量更具有科学性，

本文提出设计一套方便和精确度高的测控系统。

本文通过采用单片机作为系统的主控制器，并使用 SHT10温湿度传感器来采

集仓库中温度与湿度数据，并将采集到的模拟信号通过 A/D转换后，发送给主控

发送模块以及控制命令发送模块。主要实现的功能是对采集到的温度和湿度数据

进行分析，并且根据分析结果判断要执行的操作，从而实现对仓库温度和湿度的

精确检测和及时调控，并且向用户发送警报，当用户在认为有必要的情况下，可

以强制开关外置调控系统，从而来实现对仓库温度和湿度的有效控制。

本文中使用的单片机为STC89C52，其通过C语言编程来实现数据的测量分析和

处理。温湿度采集使用SHT10传感器，警报发送通过GSM模块采用TC35模块,目前GSM

网络的联网与漫游功能已经在全球范围内得到了实现，不须再组建专用通信网络，

所以对于通信量不大的系统设计，选择基于GSM网络的短消息数据通信是最优的。

on each other, artificial circuit to check the way to measure and record the

environmental conditions such as the mode of information, avoid many of the

catastrophic accidents caused by human factors, solve the problem of low efficiency for

talent make full use of, make the measurement more scientific, in this paper, design a

set of convenient and high precision measurement and control system.

In this paper, by adopting single chip microcomputer as main controller in the system,

and use SHT10 temperature and humidity sensor to collect the temperature and

humidity in warehouse data, and will be collected after the analog signal by A/D

conversion, sent to the main controller is analyzed to realize the monitoring of the

warehouse temperature and humidity are appropriate. Finally, this system is applied to

This system is designed by four modules, including temperature and humidity

acquisition module, the central control module, control module and sending alarm

command sending module. Main function is to analyze the temperature and humidity

data collected, and judge according to the results of the analysis to perform the

operation, so as to realize the precise detection of temperature and humidity of

warehouse and timely adjustment, and send the alarm to the user, when the user deems

it necessary, can be forced to switch the external control system, thus to realize the

effective control of temperature and humidity in the warehouse.

In this article, we use the STC89C52 as the SCM, It is through the C language

programming to achieve the measurement data analysis and processing. Temperature
