Description

CONNECTION OF THE COMMUNICATION MODULE FOR LIGHT CONTROL AND REGULATION

Technical field

The invention relates to the connection of a communication module for lighting control and regulation.

State of the art

Existing lighting intensity control systems can be controlled by switching the required number of lamps on and off. Smooth regulation of these lamps is trouble-free, but it is necessary to use the most modern control systems, which are larger and are always located in the switchboard. Control is performed by a potentiometer located in the switch.

Furthermore, integrated electronic ballasts, which are referred to as dimmable ballasts, may be used. It is verified that when using regulators operating on the principle of changing the supply voltage (amplitude), the luminous flux size can be changed only in the range from 100% to 30%. A certain disadvantage is that this control system cannot be considered to be entirely economically advantageous because of the fact that the malfunctioning of the electronic ballast elements can be affected and the consequent damage is higher than the savings achieved.

Instead, external electronic ballasts are used, which are predominantly labeled PC-A (Power Control - Automatic) and are controlled either by a DC voltage of 1 to 10V (however, an additional power supply is required here) or by an AC voltage of 0 to 230V. However, both cases of luminous flux control require additional signal wiring.

The latest generation of electronic ballasts are digitally regulated ballasts. They are usually supplemented by lighting level control also according to daylight intensity.

Furthermore, built-in radio-frequency receivers are used to control and regulate lighting, whether central locking of cars or remote control of home appliances, especially in the field of audiovisual technology. This type of control penetrates more and more into electrical installations. Remote-controlled switches or dimmers not only contribute to the increase

levels of comfort in residential buildings, but can also become part of the so-called commercial buildings. LED technology and the associated brightness control of LED and RGB LEDs are currently being promoted.

The simplest, but also the most common way of adjusting the diode current is through a series resistor, which is connected in series with the LED. To control the brightness of the LED, it is possible to use a simple regulator with a transistor, to a slightly more complex pulse width modulator - PWM. Short current pulses flow through the LED. These pulses are delivered at a much higher frequency than the human eye is able to detect, so the LED looks as if it is constantly lit. Changing the duty cycle then changes the brightness. This is a solution used especially in circuits with microcontrollers. If we have enough voltage, we can connect several LEDs in series with only one limiting resistor. The same is true for RGB Led, which is nothing but LED control, but enhanced with Red, Green, Blue. And by combining the intensity of these components, we choose the color of the lighting.

SUMMARY OF THE INVENTION

The object of the invention is to propose a wiring of a communication module which would guarantee a lower consumption depending on the adjustment of the light intensity without the need for building modifications.

The above drawbacks are overcome by the connection of a communication module for lighting control and regulation, which consists in having a communication control block connected to a communication module which is connected to at least one ballast, which is connected to at least one luminaire, with a voltage source and the current is connected both to the communication module and to the ballast.

Advantageously, when the communication module has a central processing unit interconnected with a communication interface block, the central processing unit interconnected with a potentiometer block connected to an operational amplifier block whose outputs lead to individual luminaires, the communication block is connected to a power block.

For greater reliability and more accurate control, it is advantageous if the communication module has a central processing unit connected to both the LED block, the controller connected to the voltage stabilizer block and the potentiometer block connected

to an expansion connector and to a block of communication interfaces comprising an antenna connector, wherein the potentiometer block is further connected to an operational amplifier block which is further connected to an output, wherein the voltage stabilizer block is connected to a voltage source.

Another advantage is that the wiring enables, controlled reduction of electricity consumption, control by a single control device a large number of luminaires, convenience of operation, without the need for building modifications to extend the dimming functions of any luminaire (s) (without additional wiring). Further adjust multiple luminaires, up to whole series of luminaires and create different scenes both in intensity and color. The connection of the communication module enables the regulation of the individual components of the RGB light color. Expansion example: custom scene settings, home abs simulation, market availability, no need to purchase an additional remote to purchase a new fixture.

The advantage of this controller (which is provided, for example, with the BLUETOOTH interface) is that it has a backlight that allows control of the controller's functions under any lighting conditions. The current trend of mobile phone development is indicated by the implementation of various applications in mobile phone, television, means of payment in public transport and so on.

The advantage of the wiring in which the wiring of the communication module is applied is that it works in the order of tens of connected and searched luminaires, while the maximum number can be increased by adapting the output part. Said device comprises both the control electronics located in the luminaire housing (Hardware) and the service programmed application which the user installs on a PDA, PC or notebook (Software) mobile phone and controls the control voltage of the ballast connected to the luminaire.

♦ · ♦

BLUETOOTH for lighting control and regulation according to the present invention solution will be explained on individual examples of its implementation. It is to be understood that the descriptions below are illustrative of the application of the principles of the present invention. Its application possibilities are shown in Figures 1, 2 and 3.

The basic wiring of the communication module, for example with the BLUETOOTH interface for lighting control and regulation, consists of the control block 1 connected to the communication module 2, which is further connected to the ballast 3, preferably analogue, connected to the luminaire 4. 5, which may also be part of the communication module 2

The first part is a control block 1 equipped with a communication interface (eg BLUETOOTH), which can be both a mobile phone and a classic keyboard design, a non-touch phone, or a PC, PDA or notebook, which serves as remote controls that can be expanded functions.

Another part is the communication module 2, which is the main control unit of the whole control system. This module mediates the connection between the control block 1 via the BLUETOOTH interface and the ballast 3 connected to the light source 4, e.g., a fluorescent lamp or an LED, RGB. The communication module 2 remembers the status information on the basis of which it controls the lighting parameters. In the wiring of the communication module 2 according to the invention, the wiring is fitted with a central processing unit 222 into which the control program is implemented. This arrangement of the communication module 2 has the advantage of minimizing the overall dimensions of the communication module 2 and simplifying the entire circuit, thereby increasing accuracy and reliability (without the use of components with large variations and temperature dependencies). of the whole system, since the communication module 2 consists of blocks.

A stabilizer block 230 is connected upstream of the central processing unit 222, which is, for example, fitted with a 3.3V DC stabilizer to provide a stable power supply for the entire circuit, excluding the operational amplifier block 224, which is powered directly by 12V DC. Since it is a device equipped with a central processing unit 222, a potentiometer block 223 and an operational amplifier block 224 having a very low power consumption, several tens of mA are sufficient for proper operation of the device.

The central processing unit 222 is the core of the communication module 2, controlling the operation of all other integrated circuits. In its memory, the EEPROM stores the status

information. The central processing unit 222 operates on its own protocol (value setting, save, read, name configuration, password configuration, test mode).

Potentiometer block 223 (that is, one that loses the set value when the power is turned off). These potentiometers are controlled from the central processing unit 222 via the SPI (Serial Peripheral Interface) bus. The potentiometers are intended to prepare a reference voltage for the operational amplifier block 224. The wiring diagram of the communication module 2 is shown in Fig. 3.

Operational Amplifier Block 224 - These amplifiers amplify the reference voltage to the required level for ballasts 3. Preferably, quad op ops may be used. amp. due to the small size of the housing and the possibility of supplying a relatively large current at the output. Since the operational amplifiers are connected in the usual way as a non-inverting operational amplifier, and because we only need to amplify the positive voltage, there is no need to solve the virtual ground.

A communication interface block 225 comprising a BLUETOOTH module - provides a communication link between the BLUETOOTH communication control block 1 and the CPU unit 222. The CPU unit 222 with the BLUETOOTH module communicates over a serial line (UART) over which the application protocol itself is created as above

Block of 226 LEDs - designed for visual function checking. Firstly, it indicates the proper functioning of the central processing unit 222 and, secondly, the correct operation of the potentiometer block 223 and the BLUETOOTH module. For this reason, it is equipped with a pair of LEDs.

Terminal box 227 (not shown) contains pins for supplying power from a voltage / current source 5 and ballast outputs 3.

Via the expansion connector 228, the program of the central processing unit 222 can be inserted or edited.

Power Block 5 - The entire system is powered by an approved power supply to SEC - 12V DC This Power Block 5 is not subject to the protection of the present invention, however, the power supply must provide filtered interference and parasitic interference that could interfere with proper system operation and IC damage.

The wiring function is as follows. The communication module 2, which is connected to the ballast 3 located both inside and outside the body of the luminaire 4, receives a signal transmitted, for example, via a BLUETOOTH interface from a control block 1, eg a PDA mobile phone device or a computer through this interface. Upon receipt

The signal from the control device is received by the BLUETOOTH module and is then processed by the central processing unit 222, which in cooperation with the potentiometer block 223 sets a reference voltage which is amplified to the desired level in the operational amplifier block 224. The voltage thus prepared is applied to the terminals of the ballast 3, which controls the intensity of the luminaire 4, such as a fluorescent lamp or LED. This solution makes it possible to control 2 to four ballasts at the same time 3 by one communication module, independently of each other. This means that it can control four LEDs, ie RGB and solo LEDs, or three LEDs and one fluorescent lamp 4. The solution is suitable for dimming fluorescent lamps as well as LEDs of lamps 4. Due to the very low power consumption is It is possible to control about tens of luminaires by one communication module 2. The solution includes software installed in the control module 1, which sets and controls the functions of the communication module 2. The control of individual luminaires 4 and whole luminaire groups 4 user rights. The illumination intensity status information is stored directly in the memory of the communication module 2, and each user reads the value from the memory of the communication module 2 into the application with the BLUETOOTH communication control block 1, thus avoiding different settings for individual users.

System communication security. The communication module 2 must be protected against unauthorized user misuse. This is realized by a program implemented in the central processing unit 222.

Part of the system solution is software installed in control block 1, which regulates and controls the functions of the communication module 2. This application is downloaded by the user to the mobile phone and the first time the application searches the surroundings and writes down the devices found in memory. The solution of this application is divided into two main tabs namely the service tab where the communication module 2 is searched, deleted, edited and the tabs where the list of ready communication modules 2 for use is displayed. A single telephone or a group of telephones with adjustable user rights can serve the control of the individual luminaires 5 and the whole groups. The application is designed primarily for mobile phones, keyboards and equipped with a touch screen. Communication module 2 can also be controlled by PC, PDA, notebook.

The range of the system is defined mainly by the BLUETOOTH control block 1, which is approximately 10 m for mobile phones. This range is sufficient for the system to function. The signal range of the communication module 2 fitted with the BLUETOOTH module is ideally about 100 m under ideal conditions.

signaled in the application message, which informs about the status of the signal range.

A preferred variant of the wiring of the communication module 2 is shown in FIG. 3. The wiring in this embodiment includes a central processing unit 222 connected to both the LED block 226 and the controller 229 connected to the voltage stabilizer block 230 and to the potentiometer block 223. connected to the expansion connector 228 and secondly to the communication interface block including the antenna connector 231, the potentiometer block 223 is further connected to the operational amplifier block 224, which is further connected to the output, wherein the voltage stabilizer block 230 is connected to the power supply 5 voltages.

Voltage from power supply 5 with 12V DC voltage is stabilized at 3.3V. The operational amplifier is supplied from a power supply 5 with a voltage of 12 V DC. The BLUETOOTH module sends commands to the central processing unit 222 and responds to them by sending appropriate commands to the potentiometer block 223, for example digital, or storing / reading data to / from the EEPROM configuration memory inside the central processing unit 222. output could generate a reference voltage in 256 steps. This reference voltage is then applied to one of the four operational amplifiers that are connected in the operational amplifier block 224, amplifying the voltage to the required level (0-11V) for the ballast 3.
