INTELLIGENT BUILDINGS AND HOUSE AUTOMATION SOLUTION
Intelligent Buildings and House Automation Solution can be implemented to a single building as well as a large number of buildings spread on large scaled areas and even House Estates.
System is mainly composed of two components;
CONTROL AND COMMAND SYSTEM (CCS)
It is a centralized command and control system working in interaction with separate control centers in each building which enables to manage the whole system from a single centralized point. It controls, records and monitors all parameters of the system.
Special software, named SCADA, runs on the main computer. System is composed of special hardware (PLC _ Programmable Logic Controller, Relay Drivers, Channel Control Units etc.) which is tightly integrated with SCADA software and communicates with every single sub-system on each building providing remote measurement (telemetri), monitoring (supervising) and other control ( turn on/off, regulation, alarms and functions triggered by these alarms etc.) functions.
SCADA software shows all real time operations with the help of diagrams, tables and curves on a Graphical Interface (GUI). All past operations can be stored in the desired format on a desired interval of time. System can produce necessary reports and statistics of these past operations to be able to implement its decision support feature.
A Subscriber Management System which can operate in interaction with SCADA software is also avaiable. This software has below features;
- Subscriber Records of each building/flat user (named subscriber) parameters ( electricity consumption, water usage, internet, TV, optional services etc.)
- Measuring and reporting the usage amounts in the desired time interval on any time
- Records of these amounts
- Composing invoices according to the unit prices
- In pre-paid systems generating alarms about the remaining credit amounts and functions triggered by these alarms ( turn on/off etc )
A Subscriber Management System is an interactive system which also appears as a menu item on the LCD screens of subscribers' buildings/flats enabling them to monitor their own past and real time usage amounts of electricity, water etc. and current debts.
INTELLIGENT HOUSE AUTOMATION SYSTEM (IHAS)
It controls commands and records different parameters of a house. It is composed of high a number of input devices (sensors) placed in different points in the house and output devices (relay drivers, walves etc.) again placed in different points of the house.
A microcontroller based PLC (Programmable Logic Controller) unit (which operates independently in itself) controls these input and output devices.
The user interface of the system is provided on a 15" touch screen LCD display with very user-friendly software. Though the menus are simple to use they have high visual features. The user can easily select each main menu (Lighting, security, heating, cooling) and sub menus set the desired settings (setting of each room's heat levels etc.) or can select predefined scenarios practically without getting into details.
IHAS transfers the control data and information of each input/output unit to the CCS from a copper wire (twisted pair), fiber cable or wireless (GPRS, WiFi, RF)
IHAS can also be integrated with smartcard solutions. Each subscriber with his/her photo and identity information on the smartcard can use this card
- For ID / access (as house and garage keys, turnovers etc.),
- For authentication and encryption,
- As electronic wallet for electronic commerce (e-wallet),
- As a discount card etc.
In this case Subscriber Management System can be customized for smart card usage.
IHAS can be divided into four categories;
- Lighting Automation
- Climate Control ( Heating, Cooling ) and Ventilation
- Security (Burglary Alarms, Access Security, Fire)
- Internal Communication (intercom, video camera)
Lighting Automation
Main purpose is to control all the lighting armatures inside and outside (outdoor, balconies, garden lighting etc.) the house from a single point.
A sensor that detects the daylight and lighting level inside the house, approach and motion detectors control all the buildings lighting system with the help of remote controllers, adjustable dimmers according to the lighting scenarios set by the user.
Turning on the lights automatically when the doors are opened or a car approaches the house, turning of all the lights except night lambs with a single touch of a button
while going to sleep (night scenario), setting the optimum lighting level according to the daylight (economical scenario), in case of an emergency (fire, burglary etc.) turning on/of the specific locations lights (alarm scenario), Minimizing the lighting level while leaving house (leaving scenario) are some examples of the probable lighting scenarios.
User can also set up a time table about the lighting to be used in different time intervals in a day.
All these features can also be used for the whole residential area (group of houses, retail centers, café-restaurants etc.). In this case it is not controlled by IHAS but controlled by CCS.
Climate Control (Heating, Cooling) and Ventilation
There are heat sensors placed in the different points in the building. Besides these sensors outside temperature is also measured and in centralized heated systems the temperature of the center heating water is also measured. These sensors are main input control units.
Relay drivers that control the turn on/off operation of the air conditioner, solenoid walves and 3 way walves that resides in the entrance of the building are the main output control units.
Users again can use the heating-cooling menu from the touchscreen LCD display and can set each room's temperature or the whole house temperature. He even can use the pre-defined heating-cooling scenarios without setting each room's temperature step by step.
System automatically compensates the night and day temperature differences.
Moisture and dust sensors can easily be integrated into the system. This time just like heating and cooling features, user can set the environment's moisture levels for any place of the house.
For any reason when the quality of the air decreases system automatically recognizes this and ventilates the relevant place of the house.
The scenarios that can be chosen can be just for heating-cooling features or the full scenarios that involves the whole automation features.
Security
IHAS security systems can be examined in a few subjects
Firstly there are 3 scenarios for the burglary alarm. These are;
- The whole system is turned off (off scenario)
- Only the magnetic contacts are online (night scenario)
- The whole system is turned on together with the motion and appearance detectors. (leaving the house scenario)
There are magnetic contacts on all of the windows and doors. System can recognize the positions of the doors and windows (on/off) itself.
On the other hand there are motion sensors placed on the stairs, holes, corridors etc. These motion sensors can also be placed outside the building like the entrance door.
On the alarm mode when an undesired situation occurs system sends loud and silent alarms, warning messages and reports the situation to the CCS. It also can send SMS messages and can call pre-defined numbers.
The same security system is also valid for the whole residential area. Motion detectors and
Motion sensitive cameras can be replaced among the outer walls of the area and a closed circuit television system is used for monitoring. Last 1-7 days data can be recorded multichannel on the VTR's in CCS or digitally. These cameras can be used in the whole area including retail centers and entrance and leaving points.
Another important subject is the fire alarm.
Smoke detectors which are connected to the fire santral sub-unit are used. This sub-unit reports the probable fire situation that is detected by smoke sensors to the CCS. In these cases the situation is also checked one more time from the data that has been sent from the heat sensors in the relevant area. If a fire situation occurs the system immediately overtakes the fire alarm mode.
- Loud and silent fire alarms are generated in and outside the building.
- SMS and telephone messages are sent to the relevant centers.
- All air conditioning units are turned off in order to prevent the fire and smoke to spread out.
- Lighting system is also passes to the alarm mode and can be shut down if desired.
Lastly access security is a part of the system which ensures that relevant and authorized people accesses to the relevant points. Numerical keypads, RFID tags and smartcards are used here.
The most preferred systems are active smart card-RFID systems which can operate remotely. A very effective parking management system also can be implemented with these units.
Internal Communication
IHAS may include an effective internal communication system if desired.
- Voice (telephone) and visual (video cameras) communication (café, restaurants, sportscenters, other users, entrance and leaving doors etc. )
- Wireless Technologies: With the help of miniature cameras a specific room's images can be monitored by authorized users ( by passwords or smartcards ) over internet.
- Text and voice announcements that can be done to users over the LCD displays.
