摘 要
近年来，随着科技的发展，我国农业自动化水平不断提高，信息化农业越来越受到国家政策和社会各界的重视。在农业现代化的进程中，设施农业扮演着极其重要的角色。设施农业是一种采用工程技术手段对动植物生长环境进行干预，以达到高效生产目的的现代农业方式。在越来越多科学工作者的深入研究和大力推广下，设施农业已经取得了跨越式的发展。
基于此背景，本文开展了针对物联网环境下的大棚远程环境监测系统的研究与设计工作，针对大棚环境种植影响主要的因素：温度、湿度、光照强度、CO2浓度进行研究和控制。本系统分为温室环境监测终端子系统、蓝牙无线传感网络及后台服务中心三个部分。本文主要成果如下:
设计了以大棚环境监测终端子系统为基础单元的硬件系统，硬件部分包含环境传感器与数据采集器，两者通过无线与有线结合方式连接。环境传感器将所在监测点位的环境信息源源不断地采集发送给数据采集器，数据采集器对数据进行预处理并在LCD屏上显示，同时控制加热制冷、加湿、通风补光工作，并过蓝牙模块发送到无线传感网中，满足了温室大棚内多监测点位需要同时环境参数采集的要求;系统借助蓝牙强大的连网能力，实现区域内的温室大棚在局域网内的远程监测，将物联网技术与农业生产紧密结合。
本套系统及方案适应农业现代化的要求，具有高精度、高可靠性、低成本的特点，能够满足农业温室大棚远程监测的需要，适合推广。

Abstract
In recent years, with the development of science and technology, Chinese agricultural automation level is increasing, information agriculture is more and more attention by the national policy and social from all walks of life. In the course of agricultural modernization, facility agriculture plays an extremely important role. Facility agriculture is a modern agricultural way that uses engineering technology to intervene the growing environment of animals and plants to achieve efficient production. Under the in-depth research and popularization of more and more scientists, facility agriculture has achieved a leapfrog development.
Based on this background, this paper carried out the research and design of remote environmental monitoring system for greenhouses in the Internet of Things environment, and studied and controlled the main factors affecting greenhouses planting: temperature, humidity, light intensity and CO2 concentration. The system is divided into three parts: greenhouse environment monitoring terminal subsystem, Bluetooth wireless sensor network and background service center. The main achievements of this paper are as follows:
A hardware system based on the greenhouse environment monitoring terminal subsystem is designed. The hardware part includes environment sensor and data collector, which are connected by wireless and wired. The environmental sensor continuously collects and sends the environmental information of the monitoring point to the data collector, and the data collector preprocesses the data and displays it on the LCD screen. At the same time, the data is controlled by heating and cooling, humidification, ventilation and light replenment, and is sent to the wireless sensor network through the Bluetooth module, which meets the requirements of multiple monitoring points in the greenhouse and environmental parameter collection at the same time. The system realizes the remote monitoring of greenhouses in the local area network with the help of Bluetooth powerful networking ability, and closely combines the Internet of Things technology with agricultural production.
This system and scheme meet the requirements of agricultural modernization, with high precision, high reliability, low cost characteristics, can meet the needs of agricultural greenhouse remote monitoring, suitable for promotion..
