PM-11z 植物生理生态监测系统
一、简介:
PM-11z植物生理生态监测系统是一款植物生理生态数据采集系统,运用无线传感器,可长期监测植物生理状态和环境因子,数据可通过GPRS传输,极其方便。广泛应用于植物研究和作物栽培等领域。
系统由主机、中继器、USB传输器、可选的植物生理传感器和环境因子传感器组成。
二、特点:
系统使用无线传感器,使得系统在野外的安装、分布极为方便,不必受限于传感器缆线。
无线传感器自动按照设置的时间间隔测量、存储数据,并定期和数据采集装置(比如USB传输器)进行通讯,通过数据采集装置把数据传输给用户的电脑。
无线传输距离可达4km(空旷无遮挡物)。
每个传感器可存储多7200条数据。
若干无线传感器也可通过一个中继器进行数据集中,传输给USB传输器或数据采集器。
每个无线传感器由3节AA电池供电,可工作约6个月。
PM -11z主机内置SD卡,用于存储数据;带2.4GHz RF无线通讯模块;内置GPRS模块,用户需准备SIM卡。
简单的配置可以简单到:若干(多15个)无线传感器+1个USB传输器。
可选传感器:叶面温度、茎流、植物生长、光合有效辐射、总辐射、土壤水分、温度和电导等。
可由太阳能供电装备供电(包括太阳能板、充电电池、充放电控制器及安装配件等)。
Windows版软件,可以控制主机进行数据采集与传输;显示传感器列表、数据列表;把数据导出成Excel格式。
