现代智慧农业设施大棚环境监测系统设计

Design of Environmental Monitoring System for Greenhouse in Modern Intelligent Agricultural Facilities

摘要:

在我国现代智慧农业设施大棚得到了大面积的推广使用。棚内环境是否适宜对作物的生长发育至关重要，直接决定了能否实现丰产丰收，为了确保作物在大棚中能处于最合适的生长环境，必须要对棚内的环境参数进行精确的监测。针对当前所存在的棚内环境监测系统成本较高，布线复杂等问题，提出了一种基于近距离无线组网通信技术的棚内环境监测系统设计方案。该方案选用SHT21、TSL2561、CCS811对棚内的温湿度、光强度以及二氧化碳气体浓度等环境参数进行检测，应用CC2530微处理器，对传感器捡测的环境参数进行实时采集，通过ZigBee模块将数据进行无线传输上传实现主机PC监测。系统在实际测试中温度误差不超出±0.3℃，湿度误差不超出±2%RH，在使用距离范围内的网络数据丢包率不超过2%，系统运行稳定，可靠性强，可以满足设计要求。

Abstract:

In China's modern intelligent agricultural facilities greenhouse has been widely used. Whether the environment is suitable for the growth and development of crops is very important, which directly determines whether the high yield and harvest can be achieved. In order to ensure that the crops can be in the most suitable growth environment in the greenhouse, the environmental parameters in the shed must be accurately monitored. Aiming at the problems of high cost and complicated wiring, a design scheme of indoor environment monitoring system based on close-range wireless network communication technology is proposed. This scheme selects the SHT21、TSL2561、CCS811 to detect the environmental parameters such as temperature and humidity, light intensity and carbon dioxide gas concentration in the shed. The CC2530 microprocessor is used to collect the environmental parameters of the sensor in real time, and the data is transmitted and uploaded wirelessly through the ZigBee module to realize the host PC monitoring. The temperature error of the system does not exceed ±0.3℃ in the actual test, the humidity error does not exceed ±2% RH, the packet loss rate of the network data in the range of use distance does not exceed 2%, the system runs stably and has strong reliability, which can meet the design requirements.
