A, project background
With the continuous development of science and technology, agriculture also entered the development of science and technology. In recent years, greenhouses planting in order to improve the living standard of people bring great convenience, got a rapid promotion and application. In cold winter. For greenhouses in planting environment has certain requirements. In the greenhouse temperature, humidity, light, the concentration of CO2, and other environmental factors have great influence on crop production. Through these sensor devices, the various data transmission within the greenhouse to computer software platform. Thus to control the greenhouse management.
Aiming at the trend of the development of the greenhouse, presents the design of an intelligent greenhouse monitoring system. According to the particularity of intelligent monitoring, greenhouses field parameters to managers need to transport, make superior department may at any time via the Internet or cell phone information to understand the real-time status of regional greenhouses. The intelligent greenhouse monitoring system based on GPRS make these possible
Second, the scheme analysis
1, system composition
2, greenhouses field acquisition control terminal
Greenhouses field acquisition control terminal within 24 hours to collect the greenhouse temperature, humidity, illumination, soil temperature, soil humidity, CO2 concentration, environmental parameters, such as dew point temperature.
3, wireless transmission equipment
Front end USES such as GPRS/ZIGBEE / 433 way of wireless data transmission, complete the sending and receiving information
4, the data management center
Within the data center for on-site real-time acquisition of the greenhouse temperature, humidity, illumination, soil temperature, soil humidity, dew point temperature, CO2 concentration analysis of environmental parameters such as processing, not only to complete statistics makes the corresponding statistical reports, and make trend analysis, and, in the form of intuitive graph and curve display to the user,
5, the system function
1: can online real-time continuous 24 hours collection and record the monitoring points of temperature, humidity, wind speed, carbon dioxide, illumination, and so on the various parameters, such as digital, graphics and image real-time display and record storage monitoring information in a variety of ways, monitoring points can be expanded.
2: the temperature and humidity monitoring software interface, real-time display and record the temperature and humidity of the monitoring value and the change curve, the historical data of temperature and humidity data, the maximum, minimum, and average, the accumulated data.
3: monitor host using monitoring software may at any time to print every moment of the temperature and humidity data and run reports.
4: a powerful data processing and communication ability, by using computer network communication technology, on any computer in a network can access monitoring computer, online monitoring point of temperature and humidity changes, realize remote monitoring. System can not only on duty room monitoring, the leader in his office can be very convenient to watch and monitoring.
Third, summary
Agricultural greenhouse cultivation application more and more widely, has realized the high efficiency of agricultural production, with the aid of wireless remote monitoring system is very good to solve the greenhouse plant maintenance difficult phenomenon. The application of wireless remote monitoring in the field of greenhouse planting got fully reflected, believes that the application of the wireless monitoring will also get more applications in other fields, the embodiment of the value in the Internet of things.
