Intellectual environmental monitor system scheme of greenhouse greenhouse – -Editor: It is strong in Liu the Red Army that nine is pure 15810948051 QQ786765663
The intellectual greenhouse moves the control system, it is to specially develop the environmental automatic control system of production for the agricultural greenhouse, agricultural environmental control, meteorological observation.
Agricultural environment factors such as the greenhouse greenhouse inner ambient temperature, ambient humidity, illumination intensity, soil temperature, soil moisture, density of carbon dioxide of measurable quantity,etc.,
Grow according to the greenhouse crop and require, environmental control equipments such as the automatic controlled switch window, roll membrane, air blower wet curtain, biological supplemental lighting, irrigating manuring,etc., greenhouse internal environment of the automatic regulating,
Reach the range of suitable plant growth, offer the optimum environment for plant growth. The intellectual greenhouse control system can make the greenhouse run in the energy-conserving state of economy,
Realize the unattended operation automation of the greenhouse runs, lighten personnel’s labor intensity, reduce energy consumption of greenhouse and running cost.
Two: Monitor the function:
1,Monitor the environmental factor:
( 1) Atmospheric environments: Ambient temperature, environmental relative humidity, wind speed, wind direction, the amount of precipitation, atmospheric pressure, illumination intensity,etc..
( 2) The soil parameters: Soil temperature, the soil moisture,etc.;
( 3) The ecotopes: CO2 O2 NH3,etc.;
Third, control cabinet / master controller / control device
1: The collection that the main control unit can be serial in 24 hours when the line is real, with recording and monitoring several parameter situations such as the temperature, humidity, wind speed, carbon dioxide, illumination intensity of the position,
Carry on real-time display and recording and storing and monitor information by way of many kinds of figures, and pictures,etc., it is a bit more extendible to monitor the position.
2: The data concentrator offers RS485 interface, is not mixing wirelessly and controlling the computer or controlling the computer to damages, is being paralysed, can connect the computer and derive and shift data to other computers with RS485 at any time.
3: The monitoring software of the humiture adopts standard windows 98/2000 / XP all Chinese GUIs, data value and curvilinear motion of real-time display, record every monitoring point,
Count each machine format historical data, maximum value, minimum and mean value, cumulative data,etc..
4: Data and operational report controlling the end of host computer and utilizing the monitoring software to print every moment at any time.
5: Powerful data processing and communication ability of master controller, adopt the communication technology of the computer conferencing,
The LANs any inner computer can all be visited and controlled the computer, looks over and controls the change of the position online, realize and monitor long-rangely.
