Electronic board with microcomputer and
industrial PC
in which the sensors and the commands from the
checked greenhouses are connected with the following characteristics:
As Analog inputs we consider
the sensors: pH electrodes, electric conductivity electrodes EC,
environment temperature, humidity (environment - soil),
solar radiation, luminous density, meteorological station
with control of wind speed and direction, rain control and
monitoring of environment temperature - humidity, etc.
As Digital inputs we
consider the terminal switches of exhaust windows, Hydroponics start
tray, outputs from measurement ground humidity
instruments, etc.
As Output of
the system we
consider:
-
Irrigation -
Fertigation electro valves which are possible to execute a
different recipe for each one separately (EC - pH, quota
of solutions tanks, operation time or water volume).
Unlimited electro valves regrouping and recipes with
independent different starts according to daily
repetitions, weekly, concentration of solar energy or via
the sensors in digital input.
-
Independent control of
microclimate per hall. Temperature active curves
programming with boiler, adjustment of the roof and side
exhaust windows (double-sided), fans dynamic airing,
humidyfing panel, heating curtains, etc Regulation of
humidity active curves with fogging and ventilation. Regulation of
luminous density active curves, with curtains of shading and full
operational program of artificial lighting. Additional
programmed contacts of temperature - humidity limits
(PLC).
-
Program of
irrigation electro
valves in new plants growing
-
Programmed time switches
at daily or weekly basis
