Description

The useful model of the lighting control system refers mainly to lighting systems with remote control of regulated power supply of lighting lamps, in particular to systems that provide outdoor lighting in cities, can be widely used as energy-saving electric lighting systems for streets and roads, for which the increased comfort of lighting is an important factor , and energy saving.

Known lighting systems designed to provide control of lighting elements at a distance do not meet modern requirements regarding energy consumption, quality and reliability in operation. Traditionally used control systems for electromagnetic devices powering discharge lamps have a small coefficient of effectiveness, because in addition to active power, they consume significant reactive power, which is released on the power conductors and depends on the remoteness of the location of the power supply device of discharge lamps. In this way, almost half of the consumed electricity is wasted, heating the power wires and the electromagnetic device itself.

The main disadvantages of the current lighting control systems are significant losses of electricity due to the low value of CO5Ff and low efficiency, large starting currents, conductor costs, etc. Therefore, the defining problem during the creation of modern lighting control systems is to ensure a reduction in the number of conductors, electricity consumption, and an increase in the quality and reliability of the devices that make up the systems.

The external lighting scheme is known from science and technology (USSR application Me4616276/00-07 dated 07.12.88, cl.

НО5БВИ, which is mainly used in the external lighting network with cascade switching. The device has main, intermediate and final power points. The executive point of the telemechanical control device, which is located in the main power point, is connected by a two-wire communication line with the control panel of the telemechanical control device. Current transformers are installed in the phase wires. In the above outdoor lighting system, differentiated control of sections of the lighting network is carried out. This technical solution provides the necessary mode of operation of the lighting system, has high reliability, provides the possibility of selective control of areas in the lighting network. At the same time, it should be noted that the known scheme is not energy-efficient, requires large capital investments, requires constant maintenance and personnel intervention. Modern requirements regarding the introduction of energy-saving technologies and the saving of electricity consumption are not satisfied by the given technical solution, which is its defining shortcoming.

The lighting control system selected as a prototype is the closest to the declared technical essence and achievable effect (Japanese patent VA 3-32877, cl. NOBV, 1985I), which has a main control panel in which the level setting unit is located, several final adjustment devices, optical sensors connected on one side to the console by a conductor that transmits a signal, and connected on the other side to several lighting loads. A separate line provides the connection of optical sensors that monitor the lighting in the locations of the adjustment devices for several lighting loads, and provides the possibility obtaining relevant data for making decisions about lighting control. The system regulates the light emission of loads by sending control signals from the main control panel, according to the set mode in the setpoint unit. Thus, it ensures compliance with the range of output signal levels set by the setpoint unit light control sensors to the set (set) level for each load. This design has significant advantages with the known ones, it provides probable savings in electricity costs. The introduction of additional lines for sensors, the possibility of receiving a local signal from controlled places, mainly from the locations of adjustment devices for several lighting loads, provides the ability to regulate lighting. At the same time, the prototype has significant shortcomings, which should be attributed to: a large number of conductors (provide power for sensors, control of devices and supply of control signals), lack of stabilization of the luminous flux of the lamp; fixed (during operation) and not flexible control of light flow; lack of indication of the malfunction mode of the lamp power circuit (open circuit, short circuit) and the lamp itself, lack of the possibility of automatic power off during lamp failure (malfunction); powering the lamp with current at a frequency of 50 Hz leads to an increase in dimensions, weight, a decrease in efficiency and the appearance of a stroboscopic effect.

Also, the following should be attributed to the shortcomings of the prototype. In the prototype, for the system to function, it is necessary to have two lines, such as: a line for controlling local devices and a line for connecting light sensors (the signal about the need to change the light comes via a separate line from the sensor to the main control panel), which limits the use in local lighting systems, the lighting devices of which located on unlimited (remote) territories. In addition, the optical sensors used in the prototype are unstable in operation, have a significant reading error in urban conditions, depend on the dustiness and gassiness of the environment, are sensitive to changes in ambient temperatures, which requires additional constant maintenance during operation.

Therefore, the known design is limited in its wide use, does not fully satisfy modern requirements. The presence of the above significant shortcomings became a requirement for the development and creation of more ergonomic and reliable modern systems with devices with extended functions and capabilities.

The stated design of a useful model of the lighting control system is based on the task of creating a new design of the power supply system for lighting lamps, with the possibility of controlling lighting and power on one line and ensuring continuous control of the operation of the lighting lamp, expanding the possibilities of individual adjustment settings, with increased reliability of the design, by the use of a modern element base, the combination of the power supply and control line, the introduction of the power control scheme of each lighting device and the adjusting element with smooth adjustment of the setpoint level in the power supply device of the lighting lamp.

The main essential features that are common to the prototype and the declared technical solution: a control panel connected to a current source for several networks provides power with lighting lamps, it is equipped with at least one level control unit with sensor lines connected to it according to the number of power supply devices and with at least one line a power supply to which several power supply devices for lighting lamps are connected, while one device regulates the brightness of at least one lamp.

The specified features different from the prototype meet the requirements of the novelty criterion of a useful model, and together with the features common to the prototype, the task is solved and the necessary technical result is provided.

The essence of the useful model is that the functionality of the lighting control system made it possible to change lighting technology, simplify the lighting network, and reduce electricity consumption by almost two times. Each lamp in the proposed system is powered by a discharge lamp power supply device, and a group of discharge lamp power supply devices is controlled by one power control unit, which is located in the control cabinet, from which the mains voltage of 2208, 50 Hz is supplied to the group of lighting devices. On the same cable (power and control line) of the lighting lamps from the transmitter located in the control panel, the commands to turn on (off) the lighting lamps and the command to switch to the mode of reduced lighting power are transmitted in the form of a tone signal. The transmitter, in turn, receives control commands from the lighting control system. The power supply device of the lighting lamp ensures all modes of operation of the lighting lamp, such as: ignition (ignition), current stabilization, reduced power mode, and also monitors the power circuit of the lamp (short circuit, break in the power circuit of the lighting lamp, its failure (lamp malfunction ) and signals the nature of the malfunction.Depending on the set time of gradual reduction of power for each control unit, a smooth reduction of the consumed power is carried out to the set (by setting) level for each lighting lamp.

Thus, each lighting lamp can be individually adjusted to the required power level depending on the specifics and individual factors of the location of the lighting lamp.

The main advantages of the declared useful model of the lighting control system are: - the possibility of setting a preset for each individual lighting lamp; - the possibility of individually setting the level of reduced power for each lighting lamp; - the possibility of remote control of switching on and off lighting without disconnection from the voltage network; - there is no need to use additional conductor lines for control, control and power supply is carried out via one power and control line;

- the luminous flux of each lamp is stabilized individually, according to the setting of the device from which power is supplied; - high reliability of communication because the control signals are transmitted through the power and control line of the lighting lamps.

The drawing shows the functional scheme of the lighting control system.

The system consists of a control unit 1, a dispatcher control panel 2, a power supply and control line 3, a group of discharge lamp power supply devices 4-1,...,4-i,...,4-n, connected to the control unit 1, which provide ignition and current control of the lighting lamp 5-1,...,5-i,...,,2-n, power sensors 6-1,...,6-i,...,6-n and the setpoint regulator 7-1,...,7-i,...,7-p. The control unit 1 consists of a filter 8 and a command generator 9.

The lighting control system works as follows.

When the system is turned on, the mains voltage is applied to the first input of the control unit 1, which through the control unit 1 enters the power supply and control line 3. Signals from the command generator 9, which converts the signals from the dispatch control panel, also come to the power line C through the second input of the filter 2 in high-frequency parcels. If it is necessary to turn on the lighting, the second input of the control unit 1 receives the switch-on command from the dispatcher control panel 2, which is converted into a high-frequency parcel with a length of 11, and further along the power and control line C, it is sent to all power devices 4-1.,...,4 -i,...,4-n of corresponding discharge lamps 5-1,...,5-i,...,2-P. Each of the power supply devices 4-1,...,4-i,...,4-n lighting lamps 5-1.,...,5-i,...,5- n receive and execute commands switching on, ensuring ignition, heating and operation of lighting lamps 5-1,...,5-i,...,5-n in the mode of 10095 power, controlling the power supply of lighting lamps 5-1,...,5-i, ..., 2nd according to the signal of sensors 6-1,..., 6th,..., 6th. If it is necessary to switch the lighting of any of the lamps 5-1,...,5-i,...,.5-p to the reduced power mode, a power reduction command is sent to the second input of the control unit, which is converted into a high-frequency parcel Ta2 and of the power supply line C enters all power supply devices 4-1,...,4- and,...,4-p of the corresponding lighting lamps 5-1,...,5-i,...,2-p. The power supply device 4-1....,4-i,...,4-n of the corresponding discharge lamps receives and executes the command to switch to the reduced power mode, ensuring the setting of the power level corresponding to the set point set by the corresponding set point regulator 7-1 ,...,7th,..., 7th, and controlling the power according to the signal from the corresponding sensor 6-1.,...,6th,...,6th.

If it is necessary to turn off the lighting, a switch-off command is sent to the second input of the control unit 1, which is converted into a high-frequency packet with a length of ТZ and is fed to all the corresponding power supply devices 4-1,...,4-i,...4-n through the power supply line lighting lamps 5-1,...,5th,...,2nd. Power supply devices 4-1,...,4- and,...,4-n lighting lamps receive and execute the shutdown command, while power is removed from lighting lamps 5-1.,...,5-i,. ..,9-P.

The proposed system was tested on bench equipment, significant advantages compared to known designs were confirmed. The system provides the possibility of individually setting the level of reduced power for each lighting lamp and the possibility of remote control of turning on and off the lighting without removing the mains voltage from the power line; the luminous flux of each lighting lamp is stabilized individually, according to the setting of the device that powers it; the reliability of communication is confirmed due to the transmission of control signals through the power line of lighting devices. there is
