Intelligent parking lot lighting system and its control method {SMART LIGHTING SYSTEM FOR PARKINGLOT AND CONTROL-METHOD OF SMART LIGHTING SYSTEM}

The present invention relates to an intelligent parking lot lighting system and a control method for realizing a light distribution of a Gaussian pattern, by using a digital control of the LED light that is spotlighted as a replacement for a conventional light source to configure human detection and low bit rate IR communication It is to develop a lighting device that realizes automatic power saving by only individual installation without the need for separate laying, and it is possible to realize the illumination by applying the Gaussian pattern to the brightness by the Gaussian pattern and the brightness of the space by considering the user's contrast. The present invention relates to a smart lighting device and a control method thereof.

Permanent Supplementary Artificial Lighting In Interiors (PSALI) refers to artificial lighting that assists natural lighting in buildings when natural light alone does not provide sufficient illumination or creates a satisfying atmosphere.In the case of underground parking lot, corridor and toilet The lighting must be configured with PSALI in mind. Like this, the lighting considering PSALI is a state that requires lighting continuously for safety even when the user sometimes uses the toilet and underground parking lot.

In order to solve the lighting with high energy consumption compared to the use, the automatic power saving lighting is installed through human body detection, but due to the slow response speed, the consideration of adaptation time is not considered. There is a disadvantage that a network communication network must be configured separately.

Particularly, in the case of underground parking lot, which is a typical place of artificial lighting, color temperature and illuminance environment are required to secure the driver's sufficient view and prevent the occurrence of incidents caused by dark lighting for the user's safety according to the characteristics of the space. .

Currently, as the light source of the parking lot lighting, fluorescent lamps, metal halide lamps, high pressure sodium lamps, and electrodeless lamps are selected. Among them, fluorescent lamps are overwhelmingly used, but fluorescent lamps are difficult to condense and must be used together. Since the power of the lamp cannot be changed automatically, an additional lighting control system is required. Therefore, it is necessary to overcome the shortcomings of the existing artificial light source, to prevent accident theft and damage in terms of efficiency as well as management, and to develop lighting systems and lighting devices that can be used safely and satisfactorily by users.

LED lighting can reduce power consumption by more than 50% compared to conventional fluorescent lamps, while its lifespan is more than three times longer and LED lighting can maintain a uniform illuminance distribution. It has the advantage of developing various smart lighting systems by integrating IT and advanced IT control system.

Briefly describing the flow of automatic power saving technology, a system for automatically saving power of conventional fluorescent lamps and other analog light sources requires the installation of a separate sensor unit that detects a vehicle and detects human movement. Seeking power saving. There is a disadvantage that a separate automatic power saving system needs to be constructed, and when the lights such as fluorescent lamps are turned on / off from time to time, the life of the lights decreases. In addition, in the case of a fluorescent lamp, when the ambient temperature decreases and approaches 0, redness occurs, and the light output and luminous efficiency rapidly decreases to less than 40%, and has a problem of shortening the lifespan.

Fluorescent lamps, which are currently used as parking lot lights, are difficult to collect and require multiple lamps to be used together. Since the power of the lamps cannot be changed, the power consumption is high, and the luminous flux is reduced by more than 50% when the lamp is exposed to the influence of outside air in winter. This requires a new parking lot lighting system for safety and security.

In order to reduce the energy consumption of these underground parking lots, technologies and products including automatic dimming systems using LED lighting and sensor technology are being introduced.However, these systems and products require a separate installation for network construction. In order to implement the automatic power saving function through replacement, there are problems such as unit price increase and laying work.

In order to reduce the unnecessary waste of electric energy in common facilities such as underground parking lot, and to secure a safe underground parking lot environment, the products for parking lot lighting using LED light source excellent in safety, security, and power consumption are composed in a stand-alone fashion without the network installation. It is necessary to develop the automatic power saving underground parking lot lighting only by replacing the equipment.

In particular, there is a need for a system that allows a driver to secure a comfortable and safe field of view in a parking lot environment by implementing natural dimming in consideration of human dark adaptation and perkinase transition.

According to the present invention, the present invention utilizes the digital control of the LED light, which is spotlighted as a replacement for the existing light source, and configures the human body detection and low bit rate IR communication to realize automatic power saving by only individual installation without the need for separate installation. The purpose of the present invention is to provide a smart lighting device that enables brightness adjustment using a Gaussian pattern, and brightness adjustment for a space in consideration of the user's contrast adaptation.

In particular, by utilizing the MCU used in LED lighting to the fullest, the sensor sensor control, communication control, Gaussian pattern dimming control by built-in algorithm, and integrated LED lighting and 3D Gaussian pattern to realize illumination It aims to do it.

The present invention provides the following means for solving the above problems.

When the illumination signal is changed by one unit to another LED lighting module and the sensor unit 11 does not recognize a moving object, the LED lighting unit 13 of the LED lighting unit 13 according to the illumination signal received from another neighboring LED lighting module is transmitted. It is characterized by controlling the illuminance.

In this case, when there is no illuminance signal transmitted from another neighboring LED lighting module, the illuminance of the LED illuminating unit 13 is controlled by setting the illuminance signal as a set minimum value.

In addition, when receiving an illuminance signal from another neighboring LED lighting module through the communication unit 12, the control unit 14 controls the illuminance of the LED lighting unit 13 accordingly, 1 unit to the received illuminance signal It is characterized by the transmission to other neighboring LED lighting module.

In particular, the control unit 14 controls the illuminance by giving priority to the illuminance signal according to the recognition of the sensor unit 11, and the value of the illuminance signal when receiving a plurality of illuminance signals through the communication unit 12. The illuminance is controlled by giving priority to the highest among the illuminance.

The illumination system normally maintains the illuminance of the LED lighting units 13 at the set minimum value, and the illuminance of the surrounding LED lighting modules is set to the maximum value of the LED lighting module including the sensor unit 11 in which the movement of the object is recognized. A value of the illuminance signal is set in advance so as to show a Gaussian distribution.

In addition, a plurality of LED lighting modules arranged in a grid in a parking lot, each of which includes a sensor unit 11 for recognizing moving objects within a specific distance and a communication unit 12 for performing short-range communication with another neighboring LED lighting module. In the intelligent parking lot lighting control method used,

Setting a value of an illuminance signal and an illuminance to correspond to the illuminance of an LED illuminating module sequentially indicating a Gaussian distribution by using a maximum value of the LED illuminating module having a sensor unit in which an object movement is recognized; When the sensor unit 11 recognizes the moving object, the illuminance signal is controlled to the set maximum value, and the illuminance of the corresponding LED lighting module is controlled, and the illuminance signal is transmitted to the other LED lighting module by one unit through the communication unit 12. When the sensor unit 11 does not recognize the moving object, the sensor unit 11 controls the illuminance of the LED illuminator 13 according to an illuminance signal transmitted from another neighboring LED lighting module, and transmits the illuminance received. It characterized in that it comprises the step of transmitting a unit to the other LED lighting module by changing the unit of the signal.

The control method controls the illuminance by giving priority to the illuminance signal according to the recognition of the sensor unit 11, and when receiving a plurality of illuminance signals through the communication unit 12, the illuminance of the illuminance signal is the most. It is characterized by controlling the illuminance with a higher priority.

Effects according to the present invention are as follows.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Even if the terms are the same, it is to be noted that when the portions to be displayed differ, the reference signs do not coincide.

The terms to be described below are terms set in consideration of functions in the present invention, and may be changed according to a user's intention or custom such as an experimenter and a measurer, and the definitions should be made based on the contents throughout the present specification.

The terms first, second, etc. in this specification may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component. And / or < / RTI > includes any combination of a plurality of related listed items or any of a plurality of related listed items.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise.

Unless defined otherwise, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant art and are to be interpreted in an ideal or overly formal sense unless explicitly defined in the present application Do not.

The present invention relates to an intelligent parking lot lighting system using a plurality of LED lighting modules arranged in a grid in the parking lot. In the present specification, the "lattice shape" means that the lighting modules are arranged two-dimensionally spaced apart from each other at a predetermined distance on the ceiling surface of the parking lot, and at different intervals including spaced at the same interval. It includes everything that is spaced apart.

In the case of underground parking lot, it is more difficult to grasp the traffic situation due to the large change of driving space, and it is more disadvantageous than the driver on the road.In the parking lot, the driver is looking for or confirming the parking place. Homogeneous light, high color rendering and anti-glare are required. In particular, the entrance of the underground parking lot is the boundary between the bright outdoors and the dark indoors, so that the light should be careful not to change the brightness rapidly. The underground parking lot has been designed in a quantitative manner to meet the average roughness, and the operation has been carried out with emphasis on energy saving. The operation based on average roughness is a performance evaluation made in an optimal environment, and there is a problem that it may be too difficult to apply it as it is, and cause safety problems.

The gaussian pattern and the optical characteristics of the eye, which are one of the main features used in the present invention, will be briefly described.

Experiments have shown that night vision is about 50% lower than before sunset, due to the difference in function of the cells called abstracts and rods on the retina of our eyes, because these cells do not function properly at sunset. to be.

The human eye adjusts the pupil size according to the amount of light, decreases sensitivity in bright light, and increases sensitivity in dark light. For example, when you enter a dark movie theater, it takes about 30 minutes for your eyes to get used to the darkness, and it takes about 1 minute for the brightness outside, and the former is called dark adaptation, and the latter is called light adaptation.

The Purkinje shift means that the sensitivity of the visual organ to brightness varies with wavelength. The rod that occurs during dark adaptation is more sensitive to short wavelength (blue) light than the abstract, and the abstract is more sensitive to long wavelength (red) light, which means that the visibility of long wavelength is decreased when the illumination level is decreased.

This is why red light, which was clearly visible when it became darker at dusk, became darker, and blue was clearly visible, and the emergency door light was green. The curve indicating the degree of brightness perceived by the human eye with respect to the light energy is a visibility curve, which is similar to the curve of the Gaussian distribution as shown in FIG. 1.

A Gaussian curve, called a normal distribution, is a probability distribution that is the most basic idea and basis when we deal with statistics and collects natural phenomena and plots it. It is worn. The Gaussian distribution shown in FIG. 2 is a continuous distribution having a random value within a section and becomes a key keyword that plays a very important role in understanding human life and providence of nature.

The illumination system provided by the present invention normally maintains the illuminance of the LED lighting units 13 below a predetermined value, and surrounds the LED lighting around the LED lighting module including the sensor unit 11 that recognizes the movement of an object. It is characterized by controlling the illuminance of the module to show a Gaussian distribution. In other words, while maintaining minimal illumination in general, when the movement of the object is recognized, the brightness of the illumination is controlled two-dimensionally in the area.

The automatic power saving lighting control system applying the Gaussian pattern provided by the present invention can implement a low-bit rate wireless network communication instead of a wired network method so that a power-saving configuration can be easily performed without additional installation for replacing an existing parking lot light. By detecting the movement of the vehicle and the human using the motion detection sensor, the Gaussian pattern algorithm is applied, thereby naturally and rapidly changing the illuminance.

In particular, it was developed to express the illuminance of each individual without the separate terminal control device of wired / wireless network by the control method by MCU embedded in each luminaire unit.

Referring to FIG. 3, a receiver and a transmitter for IR communication, a sensor unit 11 capable of detecting movement, and a driver for dimming control of the LED lighting unit are designed and configured on a PCB. A smart circuit unit capable of doing so is provided. The IR communication unit 12, the sensor unit 11, the control unit 14, and the LED lighting unit 13 are all configured in the integrated lighting device to form a lighting device network without additional installation. This will be collectively referred to as an LED lighting module.

The LED lighting module includes an LED lighting unit 13 with adjustable illumination, a sensor unit 11 for recognizing moving objects in the vicinity, a communication unit 12 performing near field communication with another neighboring LED lighting module, and an illumination signal In accordance with the predetermined illumination according to the control unit 14 for controlling the illumination of the LED lighting unit (13).

The main feature of the present invention is not the form of ZigBee, WiFi, which is a wireless sensor network technology that has been mainly used in order to implement communication, but an IR method used in a TV remote control, and each luminaire comprises an IR receiver and an IR transmitter. By configuring the communication unit, it is possible to implement a low-cost device compared to the existing wireless smart lighting device.

In addition, the control method by the CPU embedded in each luminaire to express the illuminance of the individual individually without the separate terminal control device of the wired and wireless network. In particular, the illumination control is set in advance so that the illuminance of the luminaire can be distributed in a Gaussian curve according to the illumination signal.

In particular, by applying a Gaussian curve algorithm to the illumination control of the luminaire, it is possible to achieve a more comfortable and safe view in the parking lot environment by implementing a natural non-linear Gaussian dimming instead of the conventional stepping dimming.

When the sensor unit 11 recognizes a moving object, the controller 14 sets the illuminance signal to a predetermined value and controls the illuminance of the LED lighting unit 13 accordingly, and through the communication unit 12. The illumination signal is increased by one unit to another neighboring LED lighting module.

In addition, when receiving an illuminance signal from another neighboring LED lighting module through the communication unit 12, the control unit 14 controls the illuminance of the LED lighting unit 13 accordingly, 1 unit to the received illuminance signal It increases by transmitting to the neighboring other LED lighting module.

In the present specification, the term "one unit" means that the brightness level of the illumination is preset in a plurality of stages to have a predetermined interval, and the difference between the stages is expressed. However, in case of 1 unit, it should not be set to have the same interval unconditionally.

For example, the value of the illuminance signal is set in advance so that the illuminance of the surrounding LED illuminating module exhibits a Gaussian distribution by using the LED illuminating module including the sensor unit 11 in which the movement of the object is recognized as the maximum value. It is done. 4 shows a Gaussian illumination pattern to be expressed in the present invention. In general, unlike the illumination values vary by the same size for each distance unit, the present invention sets the illumination signal so that different illumination values may vary for each distance unit to follow the Gaussian curve distribution. In FIG. 4 and FIG. 5, the change in the illuminance value means that the illuminance signal changes by one unit.

Figure 4 shows the change in the illumination value according to the change in the illumination signal of the neighboring LED lighting module to follow the Gaussian illumination pattern in accordance with the present invention. In the present invention, it is not controlled to change the illuminance value according to the Gaussian pattern according to the distance rather than to change the same value. When the illuminance signal is increased by one unit at the first position (which can also be reduced depending on the setting method), the illuminance value is changed to the second position, and when it is increased by one unit, the illuminance value is obtained at the third position.

In contrast, the conventional system of FIG. 5 is formed by simply proportionally decreasing the illuminance value at the first position, the second position, and the third position, regardless of the Gaussian illumination pattern.

As used herein, the term " another LED lighting module " means an LED lighting module that is arranged adjacently in a x direction, a y direction, and a diagonal direction from a specific LED light module. If arranged in a square, there may be eight.

In the present invention, the communication unit of each LED lighting module is characterized in that it can be limited to communicate with other neighboring LED lighting module. Through this, it may be possible to implement a gradation distribution of the Gaussian distribution.

4 to 7 illustrate a light distribution of a Gaussian pattern, which realizes maximum illuminance when a vehicle and a person are detected by the sensor unit, and the detected light is +1 (one unit increment or decrease) through the communication unit. Data is transmitted, and when the signal of +1 is received from the lighting next to it, it implements the value defined in the 3D Gaussian pattern. For example, this can be implemented by increasing the luminaire that receives a value of +1 through the communication unit from the initial value (for example, 35 lx) to the desired target value as a Gaussian two-dimensional curve.

In the present specification, the illuminance signal is not necessarily proportional to the illuminance value of the lighting unit. For example, when the illuminance signal is increased by one unit, the illuminance of the lighting unit may be set to increase (brighter) by one set unit, but may also be set to decrease (darker) by one unit set upside down.

In addition, in the LED lighting module for adjusting the illumination, the illumination maintaining time according to the illumination signal of the LED lighting unit is limited, and after a predetermined time passes in the state where the sensor does not recognize the moving object, the existing illumination signal is ignored and newly transmitted. The LED lighting unit is adjusted according to the illumination signal. For example, the LED lighting module that detects the movement of the car controls the illumination of the LED lighting unit at the highest brightness accordingly, but when the vehicle moves its position and the sensor cannot detect the movement, the LED lighting module located near the vehicle The illuminance of the LED lighting unit is changed according to the value transmitted from the communication unit.

Therefore, the movement of the object that can be recognized by the sensor unit should be limited to within a predetermined distance. It is desirable that the predetermined distance does not deviate from the two-dimensional area connecting neighboring LED lighting modules.

In other words, if the sensitivity of the sensor unit is so great that it is recognized until it is out of the region, the highest illuminance is generated even in a region in which no automobile, etc. exist, and thus it is difficult to implement the illuminance distribution according to the Gaussian distribution implemented in the present invention. . However, when the area to be kept bright according to the type of moving object is wide, the sensor may recognize the area beyond the area. In this case, the illuminance is maintained at the maximum value in several LED lighting units.

In the priority of the signal, sensing is the highest priority in the sensor unit, and priority is given to the smallest value received from the communication unit. That is, the control unit 14 controls the illuminance by giving priority to the illuminance signal according to the recognition of the sensor unit 11, and the value of the illuminance signal when receiving a plurality of illuminance signals through the communication unit 12. The illuminance is controlled by giving priority to the smallest value.

What has been described above is only one embodiment of generating the illumination signal in the present invention, it is also possible to reduce by one step to the neighboring LED lighting module. Alternatively, the illuminance signal may be set directly to a specific value in illuminance units.

FIG. 6 illustrates an example in which illuminance changes with respect to the LED lighting module where the movement is sensed toward the periphery, and FIG. 7 illustrates an example in which the overall illuminance is changed when an object moves to a neighboring LED lighting module through movement. It is shown. The illuminance values are illustrative only and do not limit the scope of the right.

According to the present invention, when an object is recognized through a sensor unit of a specific LED lighting module, and the object moves to another region and the sensor unit of a neighboring LED lighting module recognizes the object again, the illuminance of the LED lighting module that was initially recognized Is maintained for a predetermined time. Therefore, it is desirable not to initialize the motion because it is not detected, but to maintain it according to the input illuminance signal for a predetermined time, and to reduce the illuminance naturally by a signal transmitted from a neighboring LED lighting module thereafter. Do. Through this, it is possible to provide the effect of improving the driver's driving convenience in the underground parking lot by allowing the illuminance to naturally change instead of suddenly changing the illuminance.

LED lighting driving circuit requires a constant current control circuit to fix the current value in order to maintain the luminous flux characteristics of the LED chip uniformly.In order to supply the LED constant current, PWM control in the form of constant current receives the voltage value from the SMPS from the control circuit. The control circuit should be designed and manufactured to control the luminous flux characteristics and the lost power value by controlling it in the possible form.

In addition, the present invention is a plurality of LEDs are arranged in a grid in a parking lot, each of which includes a sensor unit 11 for recognizing moving objects within a specific distance and a communication unit 12 for performing short-range communication with another neighboring LED lighting module. Intelligent parking lot lighting control method using lighting module is provided.

This is a step of setting the value of the illuminance signal and the illuminance to correspond to the illuminance of the LED lighting module in which the motion of the object is recognized as the maximum value with the illumination value of the surrounding LED lighting module sequentially showing a Gaussian distribution. When the sensor unit 11 recognizes a moving object, the illuminance signal is set to a maximum value to control the illuminance of the corresponding LED lighting module, and transmits the illuminance signal to another neighboring LED lighting module through the communication unit 12. Transmitting by changing the unit by one unit, and if the sensor unit 11 does not recognize the moving object, the illumination of the LED lighting unit 13 is controlled and transmitted according to the illumination signal received from another neighboring LED lighting module And changing one unit of the received illuminance signal to another neighboring LED lighting module.

In particular, in the control method, the illumination intensity is controlled by giving priority to an illumination signal according to the recognition of the sensor unit 11, and when a plurality of illumination signals are transmitted through the communication unit 12, the illumination intensity among the values of the illumination signal Is characterized by controlling the illuminance by giving the highest one.

The present invention is not limited to the scope of the embodiments by the above embodiments, all having the technical spirit of the present invention can be seen to fall within the scope of the present invention, the present invention is the scope of the claims by the claims Note that is determined.
