摘要
为解决自动调控能力较弱的日光温室、塑料大棚环境信息快速获取并作出及时响应问题,设计了语音型无线环境监测系统。该系统能够获取温室空气温湿度、光照度、土壤温湿度、CO2浓度以及室外风速风向、降雨量、辐射量等环境参数并进行分析,集成专家知识库通过内嵌综合环境调控逻辑以语音方式提供相关环境调控技术服务。该系统由无线传感器节点、语音型数据采集终端以及配套软件组成,支持标准Modbus通讯协议,并在该协议构架上增加组网功能,实现4种组网用用模式。应用结果表明:该装置实现了语音提示报警功能,并具有操作简单、组网方便、功耗低等特点,满足不同设施种类、规模、资金投入需求,适合农户改变传统生产环境调控模式,为温室生产环境科学调控提供设备支撑。
This paper designed a wireless environment monitor system base on voice service, it was used for measuring enviromnent parameters and responsing to control the environment lastly in solar greenhouse or plastic greenhouse which has lower ability and equipments in control automation. This system could get the air temperature, air humidity, light radiation, soil temperature, soil humidity, carbon dioxide concentration, and also gathered the wind speed, wind direction, rain falls and radiation outside of the greenhouse. It was embedded the expert knowledge and environment control logic which was used for voice service. This system contained wireless sensor nodes, data logger and application software. All these supported Modbus protocol, and added the network maintain function. Ad hoc network also supported base on the structure of Modbus protocol. It could be networking four mode which were used for any scale of greenhouses and kinds of greenhouse. This system had the function of voice service in greenhouse climate controlling. It had simple operation, facilitate networking and low power consumption characteristics. It could be used for different greenhouse, scale ,fund and farmers. It could change the traditional climate control mode in application,
