Design of CC2530 and CC2592 based environmental monitoring system for gather greenhouses

针对集群温室大棚环境监测困难,有线传输系统成本高和网络维护量大等问题,设计了针对温室大棚内湿度、土壤温度、光照强度、CO2浓度等的无线实时监测系统。以CC2530芯片为核心,以CC2592射频前端为协助,建立无线传感器网络,对温室环境信息进行采集、分析、处理和传输,最后在上位机显示。系统详细分析了硬件电路的控制方法并给出了软件流程图。实验表明:系统可以准确获取温室环境数据。增强节点输出功率和低功耗设计,不仅提高了温室环境监测的灵活性和移动性,而且降低了成本。

Aiming at the problems of difficult gather greenhouse environment monitoring, high-cost cable transmission system and large number of network maintenance, a wireless real-time monitoring system was designed, which can monitor green- house humidity, soil temperature, illumination intensity and CO2 concentration. By taking CC2530 chip as the core and CC2592 RFFE as assistance, the wireless sensor network is set up to deal with acquisition, analysis, processing and transmission of the greenhouse environment information, which are shown on upper computer finally. The control method of hardware circuit is ana- lyzed in detail and software flow chart is given. The experimental results show that the system can obtain the greenhouse environ- mental data accurately, enhance the node output power, reduce the power consumption, improve the flexibility and mobility of greenhouse environment monitoring, and reduce the cost.
