Green House Control System GHC2

Green House Control System GHC2 Green House Control System includes Climate Controller and a number of Local Controllers forming wireless radio LAN. Each Local Controller controls one Green House module or works as Common device, servicing all network. The LAN has only one Climate Controller. In some cases the LAN could be hasn’t Climate Controller- this is the case when Green House object is small and one of the Local Controller processes as Climate Controller, connected directly to wireless internet and controlled from a remote computer. Climate Controller The Climate Controller is a process control computer capable of controlling up to 16 greenhouse modules. It can control up to 96 relay outputs connected to heating and cooling, vents, fans, Co2, boilers, lighting, shading, on-off heating valves or modulating hot water valves. Additionally it has ability for monitoring of the states of up to 704 galvanic isolated digital inputs, 64 optic-isolated 12 bits analogue inputs (0-10V), to control up to 64 analogue 12 bits optic isolated outputs (0-10V) and up to 32 optic isolated analogue outputs (0-20 mA). Being Main Operation Station of the Green House object, it supports wireless radio LAN with the Local Controllers of the different Green House modules included into the object. The Climate Controller could be accessed and controlled from external remote computer (if the last has legal access rights) using wireless internet. Features of Climate Controller: - ATX computer platform working with Windows XP/7/8.1 - Large LCD Screen Display for easy viewing - Ease to use point and click software - Climate Programs, Irrigation, Fertigation - Co2 Program - Shading, HID Lighting, and Boiler programs - Internet (Wireless) access - Wireless communication (433 MHz) with Local Module Controllers Screens and Specifications of Climate Controller (Main Operation Station) Main Screen The main screen displays a summery of the overall climate conditions in all greenhouse modules. At a glance the grower can quickly read the following conditions: - Outside weather conditions, solar, temperature, wind, and rain conditions - Temperature and humidity conditions in all greenhouse compartments - Irrigation and Fertigation schedules E.C., pH and water flow - readings Co2 Levels in each greenhouse compartment - Displays all vent positions, louver positions and cooling fan activity - Displays solar levels for irrigation triggers and solar E.C. corrections - Displays moisture levels in substrate growing medium for irrigation starts Heating Cooling & Co2 Screen - Easy to use software programs for raising vegetable and flower crops - Internet access to your Climate Object Controller from your office computer - Weather station - solar, rain, wind, and temperature programs - Heating and cooling programs for hot water, steam, or hot air heaters. - Day and night temperature and humidity programs - Temperature ramping with solar temperature programs - Co2 Programs for gas burners, Co2 boiler recovery or liquid Co2 systems - Lighting and shading programs Irrigation Screen - Irrigation, Fertigation and drain water recycling programs - Multiple Fertilizer recipes - Multiple Irrigation recipes - Programs Solar radiation - Substrate moisture level programs - Time and Solar irrigation start - E.C., pH, and irrigation water flow programs - Solar, rain, wind, temperature weather programs - Optional oxygen, pressure and water temperature programs Local Controller (Local Operation Station) The Local Controller controls the microclimate within a greenhouse block (module) or processes special functions as common device. The Local Controllers and Climate Controller are nodes of wireless LAN (using radio channel based on 443 MHz). Each LAN node is accessed from others. The Local Controller is designed as internal wireless LAN, including a number of wireless controllers (with sensors and actuators connected to them). This internal LAN is based on JENNET/ZIG BEE stack (2.44 GHz) and connects as nodes two or more differed processing devices. The minimal configuration consists SERV100+ and SIMO100+ of M2MICS, providing 7 relay outputs, 4 analogue inputs (0-10V), 4 analogue outputs (0-10V), 2 analogue outputs (0-20 mA), up to 42 optic isolated inputs. Two autonomous 1_wire bus lines allow connecting of 8 humidity sensors and 16 electronic thermometers (remote sensors). It is possible to expand the LAN with more wireless controllers and corresponded sensors if necessary. The internal LAN coordinator SERV100+ has ability to connect by wireless internet to remote computer. It makes possible it use as virtual Climate Controller (when the last is missing and the control of Green House is doing directly from a remote computer). The Local Controller does next processing: - supports measures of aspirated temperature and humidity, using corresponded sensors; - measures CO2 and controls the valves and burners; - controls PV based on SP received from Climate Controller; - connects to the common device- Weather Station, for receiving current values of “solar radiation”, “wind speed”, “direction and wind chill”, “external temperature and humidity” and “rain sensor”; - perform a given recipe. One Local Controller functions as Weather Station, giving others Local Controllers by request from them information of current values of “solar radiation”, “wind speed”, “direction and wind chill”, “external temperature and humidity” and “rain sensor”. The Local Controller supports working with: - three or four-way valves - Gas Heather; - Fan for air circulation; - Luminaire -660-670 nm; - CO2 generator; - Pump water mist; - Water fog humidity; - it is possible to be connected and working with any device, using wireless JenNet, Zig Bee or wires RS 485 , RS 232 C.
