indoor microclimate;
- increasing the efficiency of management through the integration into
ASDU.
Reduced energy consumption is achieved through the use of
energy-saving automatic control algorithms that provide
reducing the power of the lighting, heating and air-conditioning system, and
exactly:
- maximum use of natural light, application
combined room lighting modes;
- time-dependent control;
- control of the presence of people in the premises;
- the use of different modes of operation of lighting and microclimate,
taking into account the features of the use of the premises.
Apply new open technologies using intelligent
Sensors expands the area where comfort zones are created. complex
allows you to individually control the climate equipment, creating
comfortable conditions.
3. MAIN CHARACTERISTICS OF THE KNX AUTOMATION SYSTEM
The main characteristics of are as follows:
- has a modular structure and is “open”, provides, with
necessary, the ability to connect the newly installed
equipment;
- allows for the use of similar equipment of various
manufacturers;
- saves performance in general when individual fails
devices;
- has an "open" protocol and interface for interacting;
- provides a unified design and color range of control devices for and
other wiring accessories.
The service life is at least 10 years including replacement.
faulty devices. Average recovery time
makes no more than 0,5 hours. For prompt troubleshooting
equipment provides the necessary equipment reserve and the necessary
means of programming components.
4. STRUCTURE OF A SMART HOME SYSTEM
The control system of lighting and microclimate is
open source distributed automated control system
exchange for integration into the dispatch control system. Every local
device (sensor, control device, actuator)
performs its functions, and the failure of any of them does not affect the work
systems in general. All devices are combined by bus, made on the basis of
twisted pair 2x2x0.8, which serves as a supply and transmission medium.
To ensure the health of the system, the bus is kept constant
voltage 29V.
In order to increase reliability, the system has a hierarchical structure and
consists of service areas (see ECPR.12.026-AK1. C1 - Block diagram).
Each service area is an EIB line, performs its
functions independently of other zones and has a dedicated power source (PS).
Service area lines are combined into segments through connectors.
lines (LC) that perform routing functions. Segments in turn
unite in a single system.
The system consists of several subsystems that perform their functions (see
ECPR.12.026-АК1.С2 - Functional structure diagram):
- lighting control subsystem;
- climate control subsystem;
- the subsystem for controlling the curtain / louver drives;
- subsystem monitoring weather conditions.
Centralized management, monitoring and visualization are carried out.
through an automated dispatch control system.
5. LIGHTING CONTROL SUBSYSTEM
Lighting control subsystem provides manual and automatic
management of workers and emergency groups of internal lighting.
The control objects are lamps with the following types of lamps:
- incandescent bulbs for general use;
- low-voltage halogen incandescent lamps with transformers;
- fluorescent lamps with electronic control gears
(ECG);
- fluorescent lamps with adjustable electronic ballasts
devices (REPRA 0-10V);
- lamps with digital interface DALI (Digital Addressable Lighting
Interface).
Types of lighting control:
- discrete (on / off) - for all types of lamps;
- analog (change in luminous intensity) - for everyone except lamps with electronic ballasts;
- combined (execution of light scenarios).
The SWOM equipment allows to provide lighting control:
- manually (using wall mounted control panels);
- automatically (according to signals from the sensors or in accordance with the specified
time algorithm);
- remotely (using IR - control panels);
- centrally (using wall-mounted touch panels).
Internal lighting is controlled for the following
categories of premises of the complex:
- conference rooms;
- dining room;
- common areas;
- hospital wards.
Lighting and microclimate control in conference and dining rooms
the hall is carried out using temperature switches with thermostat
The switch has a display that shows
temperature, operating mode and current status (heating or cooling), as well as
Keys to control the lighting, change the temperature setting and mode of operation. Thus, this switch is a single body
control of lighting and indoor climate.
Key switch with thermostat
For conference rooms, lighting control includes turning on / off lighting fixtures, adjusting their brightness, and
use of pre-programmed "light scenes". "Light Stage" - a combination of on / off lights, their brightness, as well as the position of the blinds / curtains. Control of lighting, curtains and light
scenes "is also available from the multimedia equipment management system
during conferences and other events. For common areas, discrete automatic lighting control using motion sensors is applied (taking into account natural light and / or the presence of people in the premises).
For hospital wards, light control via motion sensors is provided.
6. MICROCLIMATE SUBSYSTEM
The main objectives of indoor climate control are
increased comfort and reduced energy consumption.
The control objects are:
- heating radiators (convectors) with control valves and
electric drives;
- closers of the air conditioning system of premises (fan-coils).
Room thermostats maintain the temperature in
room in accordance with a given algorithm, through interaction with
climate control (see Figure 3).
Figure 3. Climate control
Climate control in the premises is discrete (see
Figure 4). The room thermostat measures the indoor temperature,
compares it with the temperature setting and produces a control
impact.
The principle of operation of the thermostat
Climate control provides the following features:
- temperature measurement in the premises;
- indication of temperature and temperature setting, mode of operation;
- maintenance of the set temperature setting;
- manual change of temperature setting within ± 5ºС;
- elimination of simultaneous operation of air-conditioning units for heating and
cooling (provided by a dead zone between heating and
cooling);
- automatic and remote switching of climatic installations in
economical modes of operation: standby (STANDBY), night and protective
(HEAT / FROST PROTECTION)
Climate control in conference rooms and dining room
carried out with the help of key switches with thermostat.
To control the microclimate in the hospital wards are set
thermostats with remote control. Thermostat
originally programmed to maintain a temperature of 21 ° C and allows
promptly change the temperature setpoint within ± 5ºС from the duty nurse’s post
or from the control room. Like all other devices of the system, the device is connected to
control bus, which is electrically isolated from the power network, which
provides maximum user protection against electric shock
current.
7. SUBSYSTEM OF CONTROL OF PROTECTIVE BLINDS / BLINDS DRIVES
To create optimal conditions for lighting, as well as to reduce
loads on climatic installations on sunny days in rooms with
natural light on the windows set special sun
curtains equipped with motor drives.
The curtains are controlled automatically (by the level of the outer
illumination) or manually from a key switch.
8. MONITORING AND CENTRALIZED MANAGEMENT
has standard interfaces and an open protocol for integration into
automated dispatch control system (BACS).
Information about the state of the system is displayed on the computer screen in
form mnemonic schemes containing various dynamic elements.
Temperature indicators with a number are plotted on the layout of a building fragment.
