CONTROL AND AUTOMATION (i-DCS)

i-DCS has developed her own Embedded Development Platform: i-NOSS (iDeal-Network Operations Surveillance System). By using the Programmable Logic Controller (PLC), Router, Distributed Communication Protocol and SCADA application components, more than 100,000 Input/Output nodes can be controlled on a fully distributed environment.

i-DCS has also Mobile Control – M2M competency by adapting a variety of different communication media in i-NOSS control platform such as:

Wired Communication: RS-232 / RS-485
Wireless Communication: GSM (SMS/GPRS), Mobitex, Radio/VHF, Wi-Fi, Satellite

LIGHTING MANAGEMENT

After a series of research and development the results have proved that a ratio of %40 of total annual energy costs can be saved by implementing a fully operational Lighting Management System along with its periodical maintenance of system components.

Another fact is also found as a consequence of a research which was performed by Istanbul Technical University Industrial Engineering Department on 1998. This research exposed that optimum ilumination conditions, which differs for individuals, can increase the efficiency about %20 per employee had.

Besides there are other consequences listed below for better efficiency;

• Economical savings resulting from appropriate balast usage
• Light dimming according to the lighting needs
• The freedom for each user to decide the level of the lighting for his working area
• More efficient periodical maintenances
• Increased bulb economic lives resulting from less usage
• Cost savings related to temperature control
• To be able to control the system from computer or telephone networks in the open areas.
• Cost savings occuring from using of special switches and workmanship

On the average it is seen that on the buildings that have a good planned and implemented Lighting Management System the return of investment is less than 3 years.

GENERAL CAPABILITIES OF AN LIGHTING MANAGEMENT SYSTEM

• Turning on / off the related luminares according to the planned lumination with the help of the program tables obtained from employee.
• During day time turning off or decreasing the level of the lumination with the help of the conveniently implemented sensors that measure the intensity of the light coming from the building windows. This ensures the higher energy saving.
• When the approppriate leaving time approaches the lights may alert the employee by flashing for a period which gives the signal that lights about to be turned off. After the flashing period finishes “the turning off process” may be cancelled by pushing a button for the appropriate work area for a certain time. The flashing process restarts after a determined period of time. This period can also be cancelled over a telephone or a PC with the help of appropriate connections that were done to the telephone switchboards or PC’ s.
• Sensors (PD) may be placed in the areas like elevator corridors or fire escapes that open to office entrances so that lights can be turned on automatically while someone passes by. After a period of determined time or when the employee leaves the area and opened another office’s lights the left area’s lights may be turned off automatically
• Cleaning buttons provide the lighting activation automatically where the office cleaning takes place and turning of the other area’ s lights off with the help of “cleaning” button. The presence sensors may sense the cleaner’s presence in the room and can be turned on automatically.
• The lighting expenses for each department or each floor can be viewed from the system management software.
• For the desired floors remote turn on / off and dim can be implemented by a remote controller and again if desired these processes can be applied from a telephone or a pc.
• An override switch shall reside on each control module that provides Auto & Manual on/off command for every single module.
• The system developed as DCS and every module is intelligent, therefore modules can be placed inside the rised floors and suspended ceilings therefore also can distribute energy on the field up to 8-10 points which ensures less cabling, electric panel and labour costs.
• By sending the temperature information about the environment cooling and heating could be activated for the required parts of the building.
• Every single employee can manage their own illumination controls from their own PC’s.
• Sensors can placed into the toilets in order to activate the flushing electrovalves which results of an important amount of economical saving on water and lighting.
• The corridor lights can be controlled as to direct people to the shortest way to the exits in case of a fire starts.
• The whole system can be monitored from a graphical interface and turn on / off controls can be implemented for each area.
