智能温室远程监测系统设计(任务书,开题报告,论文11000字)
摘 要
温度是确保作物生长良好的重要因素,我国作为一个农业大国,在农业生产过程中，广泛利用温室大棚来种植蔬菜,良好的控制大棚中的温度在一定程度上可以增加蔬菜的产量,因此大棚内温度的实时观测尤为重要。传统的监测方法是人工长期监守，利用干湿球玻璃温度计现场采集数据的方式，劳动强度大，操作规程复杂，制约了温室管理员的工作效率。
现代电子技术的发展，已经渗入到人们生活的方方面面。利用智能监测系统对温室内的温度实行远程监测，不但可以解决传统温度监测的弊端，而且大幅度的提高农业生产的科技含量和生产水平，更重要的是促进了新农村建设的发展和社会的进步。
智能温室监测系统一般由信号采集系统、中心计算机和控制系统三大部分组成。此次设计主要是设计前两大部分即信号采集系统和中心计算机，对控制系统这部分并没有涉及。在本次设计中以AT89C52单片机为主控芯片，选用抗干扰能力强、精度高的DS18B20温度传感器来实现对温度数据的采集，采用C#软件编写的界面显示实时温度曲线来实现对温室的监测。
在本次设计中，用Protues8.0仿真硬件电路，以Visual Studio 2015作为软件仿真平台，联合调试共同完成了整个系统的设计，仿真效果良好。

Abstract
Temperature is an important factor to ensure the crops grow well,China as a big agricultural country,In the farming process, extensive use of greenhouses to grow vegetables，Good control of the temperature in the greenhouse can increase the yield of vegetables to a certain extent，So real-time observation of greenhouse temperature is particularly importantThe traditional monitoring method is artificial. long-term monitoring, the use of wet and dry glass thermometer on-site collection of data, labor intensity, complex operating procedures, restricting the efficiency of the greenhouse administrator.
The development of modern electronic technology, has been infiltrated into all aspects of people's lives. The use of intelligent monitoring system to monitor the temperature inside the greenhouse, not only can solve the shortcomings of traditional temperature monitoring, but also greatly improve the agricultural production of scientific and technological content and production level, more importantly, to promote the development of new rural construction and social progress.
Intelligent greenhouse monitoring system is generally composed of signal acquisition system, the central computer and control system composed of three parts. The design is mainly designed the first two parts of the signal acquisition system and the central computer, the control system this part is not involved.In this design to AT89C52 microcontroller as the main control chip, the use of anti-interference ability, high precision DS18B20 temperature sensor to achieve the temperature data collection, using C # software interface to display the real-time temperature curve to achieve the monitoring of the greenhouse.
In this design, with Protues8.0 simulation hardware circuit to Visual Studio 2015 as a software simulation platform, joint debugging together to complete the entire system design, simulation results are good.
