Description

Security light system{SECURITY LIGHT SYSTEM}

The present invention relates to a security light installed for safety in areas where crimes or accidents are likely to occur. More specifically, it relates to a security light that automatically adjusts the illuminance to a predetermined brightness level according to the requirements of pedestrians by reflecting the visual characteristics of individual pedestrians. It's about the security light system.

In general, security lights are relatively high-capacity light sources installed at considerable intervals for security purposes such as night traffic safety and crime prevention.

As the light source of these security lights, LED lamps with extremely high lifespan and electrical efficiency are mainly used. In addition, the brightness is automatically adjusted according to the surrounding light level and automatically switches to power saving mode after a certain period of time when there are no pedestrians. This method is applied to reduce power waste.

For example, Patent Document 1 discloses a method of increasing the illumination intensity when a sensor detects human movement, such as a pedestrian being located or passing within the detection area of a security light, and lowering the illumination intensity when there are no pedestrians.

However, this is a simple method of adjusting the illumination intensity step by step according to the movement of the object or a pre-entered standard value. That is, it is a structure that increases the illumination intensity above a certain level for all pedestrians without distinguishing pedestrians, so it consumes a lot of power unnecessarily, resulting in energy savings. has to be low.

In addition, each pedestrian has a different subjective brightness standard as to what level of illumination is appropriate for safe walking, so there are individual differences, such as some pedestrians feeling safe at a certain illumination level, while others feel unsafe, and the uniformly determined standard value of illumination is different from the eye. There is a problem in that it does not properly reflect the visual characteristics of individual pedestrians, such as those who need protection or are sensitive to light.

The background or prior art described above herein is information possessed by the present inventor or acquired in the process of deriving and completing the present invention, and is helpful in understanding the technical significance of the present invention and useful for prior art search and examination. It is to be noted that this does not refer to technology generally known and widely used in the technical field to which the invention pertains prior to the filing of the present invention. In addition, the reference numerals in the prior art are unrelated to the reference numerals in the present invention. .

Referring to Figure 1, the security light system according to an embodiment of the present invention includes a security light (100) installed on a light pole erected in an arbitrary location such as a pedestrian road, an alley, or a park, and a mobile terminal (200) carried by the user (pedestrian). ), and in particular, the main elements that make up the security light 100 are the LED module 110, the sensor unit 120, the wireless communication unit 130, the user verification unit 140, the memory 150, and the processor 160. ) and an LED driver (170).

The LED module 110 receives power from a separate power supply under the control of the processor 160 and emits light.

And the LED module 110 can be implemented with an LED lighting element and module that facilitates dimming, that is, easy illuminance control.

That is, the LED module 110 can adjust the brightness through modulation by turning on/off the voltage while maintaining the current supply constant under the control of the processor 160, and can adjust the brightness by the current while maintaining the voltage supply constant. Brightness may be adjustable.

The sensor unit 120 detects movement information of an object within a certain area and outputs a motion detection signal.

That is, the sensor unit 120 detects movement information of people (pedestrians) approaching or passing around the security light 100 and transmits this to the processor 160 through the memory 150 in a wired or wireless manner.

Here, as the sensor unit 120, it is preferable to use a directional sensor such as an ultrasonic sensor or a microwave Doppler sensor that detects the moving body and detects movement. Alternatively, a PIR sensor that detects the movement of an object through infrared changes or an image of a moving person may be used as the sensor unit 120. People can also be detected by analyzing the output image using an image sensor (camera) that outputs.

Meanwhile, the motion information detected by the sensor unit 120 may be information based on the movement when a person moves within the detection range of the sensor unit 120. For example, when the sensor unit 120 detects the movement of a pedestrian within a passageway, it can transmit this as movement information.

The wireless communication unit 130 periodically transmits a signal to the mobile terminal 200 and receives a wireless signal transmitted from the mobile terminal 200 to extract pre-assigned identification information to identify the user to the mobile terminal 200. do.

In addition, the wireless communication unit 130 receives an emergency call signal transmitted from the mobile terminal 200.

Here, the wireless communication unit 130 includes a communication module that transmits and receives wireless communication signals, and short-range wireless communication devices supported by the wireless communication unit 130 include beacons based on Bluetooth Low Energy (BLE). An example would be:

And the wireless communication unit 130 may operate according to the Advertise Mode or Broadcast Mode specified in the Bluetooth 4.0 specification version.

In addition, unlike the typical Bluetooth connection mode, the wireless communication unit 130 transmits an advertising packet, that is, a beacon signal, to the surrounding area without designating a specific device.

At this time, the beacon signal may include unique ID information for identification of the security light 100.

That is, the wireless communication unit 130 detects the mobile terminal 200 within a short range based on short-range communication technologies such as Bluetooth low energy (BLE) and infrared, periodically transmits various information, data, and signals, and transmits various information, data, and signals to the mobile terminal 200. ) can receive identification information.

Meanwhile, referring to Figure 2, the mobile terminal 200 is equipped with a security light 100 and a communication module for wireless communication, and searches for the security light 100, pairing for connection, illuminance, and a predetermined brightness level. An app is installed to transmit a signal to set the illuminance maintenance time and dimming time to change the brightness value, and to transmit an emergency signal.

That is, the mobile terminal 200 can connect to the security light 100 using Bluetooth, Wi-Fi, short-distance wireless communication, etc. and arbitrarily set the illuminance, illuminance maintenance time, and dimming time through user registration or authentication. .

And the mobile terminal 200 transmits identification information to the security light 100 in response to the beacon signal received from the wireless communication unit 130 of the security light 100.

Additionally, the mobile terminal 200 can receive a wake-up signal at low power through a low-power transceiver.

For example, the mobile terminal 200 may receive a wake-up signal transmitted from the security light 100 through a low-power transceiver that operates at low power while the main data transceiver, which consumes a lot of power, is turned off.

And the mobile terminal 200 can activate or keep the main data transceiver inactive based on the wake-up signal.

For example, the BLE beacon communication module operation mode of the mobile terminal 200 is normally in the first mode for battery power saving, but when it enters a certain area around the security light 100 and receives a wake-up signal, the short-range wireless communication function is activated. The state is converted to a second mode capable of receiving a BLE beacon signal, and the second mode can continue until the pedestrian completely leaves the certain area around the security light 100.

That is, if BLE beacon signals are not received from the security light 100 or are outside a certain area, the operation mode of the mobile terminal 200 returns to the first mode in which power saving is performed.

In addition, when the mobile terminal 200 receives a wake-up signal to execute the application and activate the BLE beacon communication module from the security light 100, it wakes up (drives) the application and the BLE beacon communication module corresponding to the wake-up signal. ) includes a wake-up driver that functions to wake up the device.

Here, the mobile terminal 200 may be a smart terminal in the form of a smartphone, tablet PC, laptop, or vehicle-mounted navigation device or smart device that the user can carry and has a built-in GPS sensor.

In other words, the mobile terminal 200 can access the Internet using wireless Internet, and can download and install mobile application programs through communication (data communication) from a web server such as Google Market or Apple Store, and use them. It may be a mobile device equipped with an operating system of Android 4.3 or higher or iOS 71 or higher, which can implement an interface through a mobile application.

The user verification unit 140 compares the identification information extracted from the wireless communication unit 130 with the identification information stored in the memory 150 to confirm whether the identification information is already registered.

That is, the user verification unit 140 verifies whether the user accessing the security light system 100 through the Bluetooth communication network is a legitimate registered user.

The memory 150 stores identification information of the mobile terminal 200 and illuminance, illuminance maintenance time, and dimming time setting information for each identification information.

Here, the memory 150 may be made of flash, RAM, etc., and may also store movement information of the sensor unit 120 and data about the movement information.

The processor 160 generates a dimming control signal that sequentially turns on, blinks, or adjusts the illuminance of the LED module 110 for each zone or step based on the motion detection signal received from the sensor unit 120.

In addition, the processor 160 generates a control signal to turn off the LED module 110 to reduce unnecessary electricity consumption if no one is present until a certain period of time has elapsed.

And, based on the identification information of the user confirmation unit 140, the processor 160 adjusts the illuminance of the LED module 110 according to the illuminance, illuminance maintenance time, and dimming time setting information pre-stored in the memory 150 by the user of the corresponding identification information. , generates illuminance maintenance time and dimming time control signals.

In addition, the processor 160 generates a lighting and flashing control signal for the LED module 110 when the wireless communication unit 130 receives an emergency signal transmitted from the mobile terminal 200.

The LED driver 170 controls the lighting, illuminance, illuminance maintenance time, and dimming time of the LED module 110 according to the control signal from the processor 160.

That is, the LED driver 170 adjusts the driving power supplied to the LED module 110. LED operation provides power supply according to brightness according to the control algorithm and minimizes power consumption through efficient power supply.

Here, the LED driver 170 includes PWM (Pulse Width Modulation) control. PWM control adjusts the size of the average voltage by changing the duty ratio of pulses applied within a certain period. The brightness of the light source within the LED module 110 can be adjusted depending on the size of the average voltage.

For example, the processor 160 controls the LED driver 170 step by step to control the illuminance of the LED module 110 to light at 100%, light at 50%, or sequentially lower by 25% due to current/voltage changes. can do.

Meanwhile, the security lights 100 can be installed on light poles erected at regular intervals in arbitrary places such as pedestrian roads, alleys, parks, etc. In addition, a separate management server transmits and receives data remotely using a wireless network such as the Internet. By doing so, it is possible to control and monitor a plurality of security lights 100, respectively.

Additionally, each security light 100 has a unique identifier for identification, and an IP address may be used as this identifier.

In addition, the security light 100 may automatically turn on in stages under the control of the processor 160, turn on or blink sequentially for each zone, and adjust the illuminance (brightness) to guide and induce the movement of vehicles or pedestrians.

The main operations and functions of the security light system according to the embodiment of the present invention configured as described above are described as follows.

First, the user (pedestrian) runs the app installed on the mobile terminal 200, accesses the security light 100, registers the user, and sets the illuminance standard value or illuminance level through a login process or authentication such as entering an ID and password. You can register to use the service by arbitrarily setting the maintenance time and dimming time.

And the processor 160 periodically transmits a beacon signal through the wireless communication unit 130.

In this state, when the sensor unit 120 detects movement information of an object within a certain area around the security light 100 and outputs a motion detection signal, the processor 160 receives the lighting control signal of the LED module 110, that is, the corresponding The LED driver 170 of the area generates a control signal to turn on the LED module 110 at a standard illuminance level.

Next, when the wireless communication unit 130 receives a response signal to the beacon signal from the mobile terminal 200, it extracts identification information previously assigned to the mobile terminal 200.

Next, the user confirmation unit 140 compares the identification information extracted from the wireless communication unit 130 with the identification information stored in the memory 150 to confirm whether it is pre-registered identification information.

Subsequently, the processor 160 determines the LED according to the illuminance, illuminance maintenance time, and dimming time setting information previously stored in the memory 150 by the user of the mobile terminal 200 based on the identification information confirmation result of the user confirmation unit 140. Generates a control signal for the module 110.

Next, the LED driver 170 in the corresponding area controls the LED module 110 to adjust the illuminance, illuminance maintenance time, and dimming time according to the user's setting information.

In other words, dimming control is used to adjust the LED module 110, which is turned on at the standard illuminance by the body movement detection signal of the sensor unit 120, to the maximum brightness for a set time, or to lower it to the minimum illuminance after the set time has elapsed. It can be done.

Additionally, if a user (pedestrian) passes through the area and there is no response signal to the beacon signal, dimming control may be performed to lower the maximum illumination state back to the standard illumination level.

For example, among the security lights 100 installed at regular intervals, the illuminance of the security light 100 closest to the mobile terminal 200 is gradually controlled to be brighter or illuminated at 100%, and the remaining security lights ( 10) and the illuminance of the security light 100 located at the rear where the pedestrian has already passed is controlled to be dimmed to 50% at once or lowered by 25% sequentially, so that the pedestrian follows the security light 100 that becomes brighter sequentially. You can move safely.

Furthermore, when the wireless communication unit 130 receives an emergency signal transmitted from the mobile terminal 200, that is, a signal transmitted by a user (pedestrian) to notify the occurrence of an emergency situation, the processor 160 turns on the LED module 110 and A blinking control signal is generated, and the LED driver 170 in the corresponding area controls the LED module 110 to turn on all LED elements to increase illuminance to the maximum or control them to blink at maximum brightness for a certain period of time.

As another example, an emergency light that turns on the LED module at maximum brightness when receiving an emergency signal can be installed on the light pole.

In addition, the emergency light can turn on emergency lights installed on neighboring light poles at the same time, so that when pedestrians are in danger, they can be protected from danger by informing them of the danger through brightness.

As another example, a camera that captures surrounding images may be installed on the light pole to store the captured images.

In addition, a dangerous situation can be determined through the captured image and notified to the surroundings or emergency lights can be turned on, and the dangerous situation can be determined through previously learned stored information.

In addition, the power supply device (SMPS; switched mode power supply) applied to the present invention to supply power may further include a power control unit that controls power for efficient and stable supply of energy, and the power control unit Can control the LED module 110 connected in parallel, as well as emergency lights, cameras, etc.

Meanwhile, the present invention is not limited to the above-described embodiments and the accompanying drawings, and may be modified and applied in various ways not exemplified without departing from the technical spirit of the present invention. It is clear to those skilled in the art that the present invention can be broadly applied by replacing components and changing it to other equivalent embodiments.
