Description

The utility model relates to the equipment of municipal equipment of residential buildings and industrial and office premises, and in particular to systems (devices) for automatically controlling electrical quantities, in particular, to devices for automatically controlling lighting devices for various purposes.

A lighting control device is known (RU 2001125028, 2001) [1], comprising a primary converter comprising an RC oscillator with a photocell included in a timing circuit; secondary converter, which includes: power supply unit; line control module; microcontroller; amplifier-driver with a characteristic of the type "hysteresis"; switch; display module and lighting control module; modules of floor lighting switches containing a smooth on-off circuit, a motion sensor and a timer - one per floor.

The disadvantages of this device are: round-the-clock operation of the primary converter; the presence of switches on each floor; one lighting control channel, if we take into consideration one residential building, the device controls the lighting of one entrance; the absence of a second control channel for emergency lighting (in high-rise buildings there are halls and walkways where it is necessary to control the lighting during daylight hours), when the primary converter fails, the lighting is switched on and its manual control using a switch is necessary; increased electrical hazard - lighting may turn on at the time of replacement of failed lighting lamps and injure a person.

The closest analogue of the proposed technical solution is a lighting control system (device) comprising a controller connected to photosensors and control channels, and

having discrete inputs and discrete outputs. Two lighting control channels are used in the device: the first channel, the standard one, controls turning on and off the lighting in the dark, the second channel controls the lighting of rooms where lighting is needed and in the daytime - elevator landing sites, the ground floor hall, corridors and platforms with insufficient lighting during daylight hours. The control is carried out not by turning on and off the lighting, but by controlling the brightness of the illumination of the lighting lamps, network power controllers and switches with a mode of smooth on and off voltage are used (RU 2249925, publ. 2005).

The disadvantages of the closest analogue are the presence of only one smooth control channel, which is not able to provide rational lighting in rooms with different levels of natural light penetrating into them (in the standard entrance of a residential building, as a rule, there is a room that does not have windows that needs to be lit around the clock, there is a room with a standard window opening and there is a room with a reduced size window). If you use the smooth control channel only for rooms without windows, and in other rooms turn on and off the lighting discretely, then the economic effect will be insignificant. In addition, the closest analogue does not provide "energy-saving" control for lighting basements, attics and architectural lighting.

The technical problem to which the utility model is aimed is to increase energy savings, the life of incandescent lamps, reliability and comfort of use.

The problem is solved in that the lighting control system comprising a controller connected to photosensors and control channels, and having discrete inputs and discrete outputs, contains at least eight control channels, each of which is controlled by the controller according to an individual program, three of which

these channels are connected to separate power modules for smoothly controlling the brightness of the lighting lamps, and five of these channels are connected to discrete outputs, while the number of discrete inputs is at least four.

In private versions of the utility model, the photosensor for measuring the level of illumination (natural light) has an integrated microprocessor and an RS-485 interface module for communication with the controller.

The controller has a two-line 16-character liquid crystal display, four-button keyboard for programming, a real-time clock, 4 discrete inputs of the “dry contact” type, 6 discrete relay outputs and an RS-485 interface module for communication with the photosensor and power modules.

Power modules are designed to continuously control the brightness of lighting lamps, which in the device (system) can be up to 128 pcs. per controller, depending on the lighting load of the building. Power modules are based on IGBT keys, have their own microcontroller, a forced cooling system for power element radiators, an interference filtering system, and an RS-485 interface module for communication with the controller.

The first (D01) of discrete channels is used to control communal lighting (lamps at entrances and waste bins), the second (D02) - facade lighting (illumination of the pre-house area), the third (D03) - lighting of the basement, 4th (D04) - attic lighting, 5th (D05) - architectural lighting of the building.

6th - a channel for continuously regulating the brightness of lighting lamps is made for entrance rooms of a residential building that do not have windows, for example, a platform at the entrance doors to apartments (a separate power module); 7th - a channel for continuously regulating the brightness of lighting lamps for rooms of an entrance to a residential building having standard-sized window openings, for example, an elevator hall (separate power module), 8th — a channel for continuously regulating the brightness of lighting lamps for premises of a residential entrance

houses with window openings of a reduced size, for example, an interfloor flight of stairs (a separate power module).

The proposed device (system) has 4 discrete inputs of the “dry contact” type: 1st (DI1) - for connecting to a building fire alarm station: in case of fire (contact closure of DI1 and Com) lighting on the 6th, 7th and 8th its smooth control channels at night are turned on at full power to ensure normal evacuation of people from the building; 2nd (DI2) - for connecting to the elevator automation system: in case of elevator malfunction (closing of the DI2 and Com contacts), the illumination of the 3rd smooth control channel (mezzanine) is switched on at full or increased power (programmed) for comfortable movement of residents between floors at night; 3rd (DI3) - programmable button to turn on the basement lighting; 4th (DI4) - programmable button to turn on the attic lighting.

The device may have additional discrete inputs and outputs for control channels.

The essence of the utility model is explained using the device diagram and structural diagrams of the elements making up the device. Figure 1 shows the general diagram of the device, figure 2 shows the structural diagram of the controller, figure 3 - power module, figure 4 - photosensor.

Figure 1 shows:

D11-D14 - discrete inputs of the "dry contact" type, D15-D16 additional discrete inputs of the "dry contact" type - for the future.

D01-D05 - discrete control channels, D06 - for the future. discrete control channel.

An example of the proposed device (system) lighting control.

The photosensor converts an analog signal proportional to the light level into 99 levels of a discrete value and transmits it to

controller via RS-485 network. The current signal value is displayed on the controller display.

The controller receives signals from the photosensor, digital inputs DI1 - DI4 and controls the digital outputs D01 - D05 and three smooth control channels according to the program.

Channel 1 D01 Public lighting is a twilight switch with its own programmed threshold;

2nd channel D02 facade lighting is also a twilight switch with its programmed threshold. In channels 1 and 2, a trip delay of 40 seconds is provided for protection from dazzle of the photosensor, for example, by car headlights.

3rd channel P03 basement lighting - controlled by a button connected to a digital input DI3. Programmable lamp time when pressing a button once. For example, if 1 press = 10 min of the operation of the D03 output is programmed, then by pressing the button 3 times, we get 30 min of the basement illumination work, after which it will automatically turn off, warning about this for a short flash. This function is convenient for routine bypassing basements and attics with utilities, because you do not need to return to the 1st entrance again to turn off the lights.

4th channel D04 attic lighting - similar to 3rd channel.

Channel 5 D05 The architectural illumination of the building is switched on simultaneously with the facade lighting. Then it turns off at night at the programmed time and turns on again at the programmed time in the morning. It turns off completely simultaneously with facade lighting.

The 6th, 7th, 8th channels of continuous lighting control are made in the form of separate power modules and each operate according to its own program, receiving commands from the controller via the RS-485 network.

For these modules, the day is divided into 9 time intervals, during which different signals for controlling the power of the glow of the lamps are given to the corresponding power modules. For example, 0:00 - 6:00 - 40% of the nominal for channels No. 6, 7 and 55% - for channel No. 8; 6:01 - 8:00 - 100% of the nominal value for channels No. 6, 7 and 80% of the nominal value for channel No. 8, etc. At the same time, the output signal level of the power module is also divided into 99 units of brightness level and is displayed on the controller display. To correct the degree of regulation in rooms with windows, depending on the level of illumination in the street, the controller uses the signal received from the photosensor. When the natural light level reaches the programmed threshold value, the controller turns off the lighting in channels 6, 7, 8.

On weekends, the lamp brightness level can automatically increase by a predetermined amount (programmed, for example, by 20%).

The program provides automatic adjustment of the degree of brightness control when replacing lamps of one power with another (correction factors are introduced, which eliminates the re-adjustment of the system when changing lamps).

If incandescent lamps are used, they turn on smoothly, which significantly increases their service life.

The advantages of the proposed lighting control device:

- Significant energy savings in the operation of residential lighting systems by regulating its power depending on the time of day and on the flow of people moving around the building;

- rational use of architectural lighting of the building;

- the lighting of basements and attics cannot be left on for

a long period of time due to the negligence of the staff serving the building;

- extension of the service life of incandescent lamps (up to 5 times) in smooth control channels;

- Communication with other engineering systems of the building (fire alarm, elevator facilities);

- a large allowable distance between the location of the system elements (photosensor, controller and power modules) at the facility - up to 1.2 km through the use of the industrial communication interface RS-485 (two-wire line);

- the use of the principle of “all devices in one” - the management of the entire lighting load of a building or residential building using one device.
