Irrigation Controllers

Bridge Irrigation systems are carefully designed to give optimum irrigation performance. In order to achieve this, some level of automatic control is required for the irrigation system. This control can either come from a main horticultural management system, or from a standalone irrigation controller. Bridge can offer a range of Galcon products to suit the control requirements of any nursery or farm establishment. These Galcon products range from the simple AC24 Irrigation Controller for small nurseries, to the Galileo controller which has the ability to control climate as well as irrigation in glasshouses and farms etc.

With the use of Remote Terminal Units (RTU) it is simple to control vast open field irrigation networks from one central controller.

AC24 Irrigation Controller

This is a fully programmable controller, with 8-24 stations, intended for smaller glass houses and professional gardens (parks, golf courses etc.).

ac24Features:

  1. 8,12,16,20 & 24 stations
  2. Single Housing
  3. Modular Expansion
  4. Weekly Program
  5. 4 Start times per daily program
  6. Cyclic program – 1 to 30 days
  7. Programmable “Rain Off”
  8. Master valve/pump start
  9. Programmable fertiliser valve
  10. Programmable lighting control
  11. Built in Transformer

Gal-Star

The Gal-Star is Gal-Star is a medium size controller, capable of controlling two irrigation heads/manifolds

Its software includes all the programming features of an irrigation controller including fertilization according to ECpH. It is designed to be operated via the wide screen and keyboard but is also capable of communication with a PC.

The keyboard is designed in a similar fashion to automatic telling machines (with function keys) and therefore the controller is very user friendly. It provides remarkable sophistication in relation to its size.

All of the models are available in AC or DC.


Galileo

Galileo is a computerized agricultural control system, among the most advanced in its field.

It can be used for climate control and irrigation in green houses and irrigation control of large open fields, farms, orchards, turf, public gardens and more.

The Galileo can be supplied in different cases depending upon the number of Input/Output slots required.

This controller can be supplied with powerful software to meet your exact requirements, whether you need glasshouse irrigation, open field irrigation, or full glasshouse climate control. When connected to a PC this software has a user friendly graphical display.

Galileo – Connection to a Central PC Computer

Galileo controllers can easily be connected to a central PC computer either by:-

  1. Direct cable connection – range up to 20m
  2. Long distance cable by a special cable modem (L485) – range up to 4km
  3. Radio communication – range up to 20km (extra range can be achieved using repeaters)
  4. Cellular modem (using GPRS).

The advantages of connecting the controllers to a PC are:

  • Remote Control: Instead of working out in the field it is possible to carry out the same tasks from the comforts of your air conditioned office.
  • Central Command: Several Galileos can be connected to one computer, allowing the control of a very large area from a single location.
  • Graphical Presentation: It is possible to see an on-line presentation of the field showing all active elements and the system status in an understandable, familiar way.
  • Data Acquisition: The computer can collect a variety of types of data such as Valve Accumulations, Water Meters, Water Meter Flow Rates, Irrigation Information and more. Many types of reports and graphs can be shown. The reports can be set for ranges varying from a single hour up to a full year. Some of the reports are highly specialized, for example a report of fertilizer elements (nitrogen, phosphorus, potassium etc.) per valve. The data can be exported to an Excel data sheet for further analysis.

Glasshouse Irrigation:

The system is composed of one irrigation head in which a fertilizer centre performs sophisticated fertilizer injection of up to 8 different fertilizers whilst carrying out the essential control of conductivity and acidity of the irrigation water.


Open Field Irrigation:

This unique application is designed to provide a solution for a wide variety of irrigation needs. It can be used in very small irrigation systems such as a home garden or for the largest systems such as irrigation communities. The system fully supports the use of cable and radio RTU.

Greenhouse Climate Control:

The system includes a large diversified and flexible software package that can be fitted to the use of almost any farmer without any special modifications. This software can monitor internal sensors such as temperature, humidity etc, as well as external sensors via a weather station. It can control up to 4 zones, each containing Vents, Screens, Cooling, Heating, CO2 Enrichment, Irrigation, Air Extraction Fans and Air Circulation Fans.

Galileo Alarm Activation

This addition to the Galileo will be activated in the case of system failure such as over/under flow rate, uncontrolled water, missing water meter pulse and extreme climate conditions. Alarms can be issued via an external device such as siren or a flashing light. They can also be sent as an S.M.S text message to a mobile phone or as an email.
