【摘要】：传统的环境或温室信息查询需要在现场由人工采集或者通过有线传输监测点的实时数据,而需要放置环境监测设备的地区有时较为恶劣,甚至缺少电力供应,采用有线传输信号投入较大,且施工困难,采取人为现场检测和记录数据的方式耗费时间和人力资源。这些监测方法中设备获取的环境信息(传感器种类)种类无法根据用户要求定制,也无法对特定的小范围地域环境信息实行监测,市场上现售的无线监测装置体积较大、较昂贵、移动不方便,并且缺少远程控制执行机构的功能。基于移动网络的多传感信息查询和控制系统由太阳能电池供电,绿色且移动灵活,大气或温室内的温度、湿度、光照度、气压、CO2浓度环境信息不仅可以在液晶屏上本地显示,也可通过手机指令进行实时查询,获取到包含多路环境信息的短信,当有环境信息超限时可以短信报警。当用户远行时,可以通过发送短信指令远程开启水阀等执行机构,达到灌溉等目的。本系统首先远程查询到环境中多路传感器的综合实时信息,从而判断大气或温室环境的状态,进而远程控制和优化环境的不利因素。本系统能够以低成本给用户远程提供精准环境信息和控制功能,可以让用户实现无人值守的监测和控制功能。
[Abstract]:Traditional environmental or greenhouse information query requires real-time data collected by manual or wired monitoring points on the spot, while the areas where environmental monitoring equipment needs to be placed are sometimes worse, or even lack of power supply. It is difficult to use cable transmission signal because of its large input. The use of artificial on-site testing and recording of data consumes time and human resources. The types of environmental information (types of sensors) acquired by equipment in these monitoring methods cannot be customized according to user requirements. It is also impossible to monitor the environmental information of a specific small area. The wireless monitoring devices available on the market are larger in volume, more expensive, and inconvenient to move. The multi-sensor information query and control system based on mobile network is powered by solar cells, green and mobile, temperature, humidity, illumination in atmosphere or greenhouse. The environmental information of atmospheric pressure and CO _ 2 concentration can not only be displayed locally on the LCD screen, but also can be queried in real time by the command of mobile phone, and the short message containing multi-channel environmental information can be obtained. When there is an environmental information exceeded the limit can be SMS alarm. When the user is far away, you can send short message instructions to remotely open the water valve and other executing agencies. In order to achieve the purpose of irrigation, the system first remotely inquiring the comprehensive real-time information of the multi-sensor in the environment, so as to judge the state of the atmosphere or greenhouse environment. The system can provide users with accurate environmental information and control function at low cost, and can realize the monitoring and control function of unattended users.
