无线温度湿度采集系统设计(任务书,开题报告,论文14000字)
摘要
温湿度自古以来就是人类最关心的自然环境因素之一，其对工农业的生产有着巨大的影响。在现代科学中，一些物品的储存环境和工具使用环境都有严格的要求，温湿度的细微差别也会影响工具的灵敏度和安全状况等。在温湿度采集的传统模式中，人工手持传感器进行各个区域的检查是最经常使用的。这种人工巡查的方式不仅不能实时监测环境的温湿度情况，而且耗时长，效率低，对于一些人不能进入的场所无法进行检测。本次设计使用智能传感器和单片机配合的方式解决了以上问题。此次无线温湿度采集系统的主要目的是节省采集成本且能实时监测温湿度变化并及时预警。系统设计中包含主机和两个从机，芯片采用STC89C52单片机，环境数据采用国产数字传感器DHT11来进行实时监测，两路从机负责数据采集，主从机间用NRF24L01无线模块通过查询方式进行通信，最后主机接收相关数据并显示，并通过芯片内部程序编程判断温湿度上下限是否达到报警值从而决定相应的报警指示灯亮灭和蜂鸣器的开关。通过设计相关电路和实物焊接调试后，电路能实时测量和告警，满足了设计要求，达到了低成本高效率的要求。

Abstract
Temperature and humidity have been one of the most important natural environmental factors for human beings since ancient times, and they have a huge impact on the production of industry and agriculture. With the rapid development of modern science, the nuances of temperature and humidity will also affect the sensitivity and safety of the tool. In the traditional mode of temperature and humidity acquisition, manual hand-held sensors for inspection of various areas are the most frequently used. This type of manual inspection not only fails to monitor the temperature and humidity of the environment in real time, but also takes a long time and is inefficient, and cannot be detected in places that some people cannot enter. This design uses a smart sensor and a single-chip microcomputer to solve the appeal problem. The main purpose of the wireless temperature and humidity acquisition system is to save the collection cost and monitor the temperature and humidity changes in real time and timely warning. The system design includes the host and two slaves, the chip adopts SCM single chip, the temperature and humidity sensor selects the domestic chip DHT11, the wireless transceiver module selects NRF24L01, the two slaves send the collected temperature and humidity to the host display, and pass the chip internal program. Program to determine whether the upper and lower limits of temperature and humidity have reached the alarm value to determine the corresponding alarm indicator light off and the buzzer switch. After designing the relevant circuit for physical welding and debugging, the circuit can measure and alarm in real time, The design indicators have basically reached the original purpose, solving the problem of high cost and complexity in the field.
