Description

Street lamp providing the function of controlling the blinking or illuminance of the lighting lamp by using the motion detection function of the camera sensor {The streelight which has lamp on / off and step-dimming control function by the motion detection of camera sensor}

Many street lights or security lights are installed on the roads, helping to keep the vehicle safe and pedestrians safe at night. The flashing driving conditions of the current street light, the daylight conditions around the street according to the sunrise or sunset; A time condition reflecting the average value of the sunrise or sunset accumulated for several years in response to the seasonal environment for each year 365 days; And weather conditions that reflect a sudden change in weather deterioration regardless of sunrise or sunset; Composed of any one or two or more of the combined conditions and operating in conjunction with the control device to blink the street light. Because of this control device, even if there are no people or vehicles on the road that the street lamp is in charge of, the street lamp should be turned on according to the flashing driving conditions above. There is. In particular, since late-night and early morning vehicles and pedestrians moving on the road is more rare, this waste tendency is considered to be a big problem. When the mobile communication module is installed on the street lamp, the lamp is turned on at sunset time and the lamp is turned off at sunrise time, and when a special situation occurs, for example, when it suddenly rains a lot and gets dark faster than usual. A system for turning on street lamps in remote locations has also been developed, but they are not activated due to their lack of energy savings.

In order to achieve carbon emission reduction targets and save energy globally, various efforts are being made, including applying various types of smart grids and power-related information and communication technologies to the power industry. Using LED light as a street light, a way to save energy while maintaining current lighting levels, can save more than 40% of the energy of a conventional metal halide street light. Therefore, by using the step-dimming function that can gradually adjust the brightness of the light, you can save an additional 50% of energy while maintaining the security of the city. There are 20 million street lamps in Korea, and when they use LED street lamps (50,000 hours of LED bulb life), they consume about 120W of power, which is about 2.4 million KWh (200,000 KWh of Soyang River Dam). It is being consumed. The present invention relates to a field for dramatically saving street light-related power energy consumption by applying a technology to turn off a street light or extremely low illumination when there are no vehicles and pedestrians using the road.

In the absence of vehicles and pedestrians using roads, sensor technology is needed to detect the presence of vehicles and pedestrians on roads in order to turn off the streetlights or to reduce illumination. At present, the proximity sensor that blinks the entrance entrance lamp using the infrared sensor, or the presence of the vehicle in the parking space in the parking lot by using the ultrasonic sensor is widely used as a tool to make life easier. Although the distance that can be detected using infrared or ultrasonic sensors can be detected within 10 ~ 30m, it is impossible to reliably detect pedestrians or vehicles that move within 30m of street lamp installation with current proximity sensors. In the case of tunnels, there is only one entrance and one exit, so a vehicle sensor is installed at the entrance to turn on the lamp in the tunnel only when the vehicle is in the tunnel.However, in general roads, pedestrians as well as vehicles must be detected. Due to the variety, a light control system in the form of a simple entrance and exit structure such as a tunnel cannot control a street lamp installed on a road. It is impossible to detect pedestrians when using the vehicle sensor installed at the bottom of the road. However, if the captured image processing technology of the camera sensor can be applied, it is judged to be the only solution that can automatically detect the movement of vehicles and pedestrians. In order to detect the movement of vehicles and pedestrians using the camera sensor, the camera sensor must be fixed and the change of movement can be determined by comparing the captured image data.

The present invention relates to a street lamp that can significantly reduce the unnecessary energy consumption of the street lamp by applying a technology to turn off the lamp or extremely low illumination when there is no vehicle and pedestrian using the road. In order to implement this, even when the camera sensor is installed in the street lamp and the lighting time according to the driving conditions of the street lamp flashing, when there are no vehicles and pedestrians using the road (when there is no movement), the illumination of the street lamp is reduced or turned off. Generally, the installation distance of street lights and security lights is about 30m, but considering the moving speed of the vehicle and the driver's viewing distance, it should be able to detect the movement of the vehicle 100 ~ 200m ahead. In the case of pedestrians, the movement speed is not large, but it should be able to detect movements 100m ahead considering pedestrian vision. In order to detect further movements, a wireless network must be established between streetlights to be configured to transmit motion detection data to each other. That is, by combining such motion detection data, it should be possible to efficiently control the illumination and turn off of each street light.

The technology of detecting movement change by using a fixed camera sensor is widely used, and a motion detection function is selectively provided on the back end chip of the camera sensor even without a complicated program. When the camera sensor moves (for example, a PTZ camera), it is very difficult to implement a motion detection function because the video to be compared is constantly changing. According to the present invention, if one or four camera sensors are installed according to the wall area of the street lamp, if the motion is not detected from all the camera sensors, the illuminance of the street lamp is lowered or turned off, and if the motion is detected from the camera sensor, the street light is originally illuminated. It can be solved by configuring it in the form of raising or lighting. The general camera sensor used in smartphones has a visible distance of about 200m, and even if a 2M pixel camera sensor is applied, the reliability of the motion detection function is high within that distance. In the case of camera sensor, power consumption is about 50mW, so if 4 camera sensors are installed, it is about 200mW, which is very small compared to street lamp energy consumption. When the lens of the camera sensor is a fisheye lens, one camera sensor can detect whether there is a moving object in a large area. In the case of the rear camera currently applied to the vehicle, it is a step of applying a fisheye lens and restoring an image, and also has a function of discriminating a parking line. In order to prevent confusion of pedestrians and drivers of vehicles, the street lamps are turned on and off from time to time so that moving object information around adjacent street lamps can be received through a wireless communication network for comprehensive illumination control, light off, and lighting. May be configured to maintain the state for a certain time.

Even in Korea, there are 20 million street lights nationwide, and the current street lights are turned on and off uniformly by the flashing control device according to the sunset and sunrise time set for each season. In recent years, if the ambient light is measured and the brightness is bright, energy saving may be achieved by lowering the brightness of the street light, but the effect is minimal. In order to fundamentally eliminate unnecessary power energy waste, when there are no vehicles and pedestrians on the road, the following effects can be expected if the street lights can be turned off or the illumination can be lowered a lot, as in the present invention.

First, if there are no vehicles and pedestrians passing through the road, the streetlights are turned off or the illumination is reduced a lot to reduce the meaningless energy consumption due to the lighting of the streetlights.

Second, the fact that street lights or security lamps are turned on and off depending on the surrounding conditions, recording them with a camera can reduce crimes by criminals.

Third, when the street lamps are connected to each other by a wireless communication network, there is an effect of efficiently controlling lighting in connection with surrounding street lamps according to the movement of vehicles and pedestrians.

Fourth, if the camera sensor is equipped with a function to record important scenes in the flash memory, such as a car black box, it can provide important investigation data in the event of an accident or a crime near a street lamp.

In the case of the current street lights that are operated by the flash control device based on the stored sunset time information, even if there are no people or vehicles on the road in charge, the street lights are turned on according to the above specified flashing driving conditions. There is a serious problem that unnecessary energy is wasted due to the meaningless lighting of street lights. In particular, since late-night and early morning times, vehicles and pedestrians moving on the road become less rare, such a tendency to waste energy is considered to be a big problem to be solved. To solve this problem, a sensor system is needed to detect whether there are moving pedestrians and vehicles on the road in the area covered by the street light. Existing infrared or ultrasonic sensors are not enclosed spaces. Can not determine the movement of vehicles and pedestrians at a reliable level. Accordingly, in the present invention, it is possible to determine whether there is a moving object on the road by using a motion detection function for capturing an image of a wide overall space opened by one or more camera sensors to determine whether a motion has occurred. In the absence of a moving object, the street lamp is turned on or off to provide a way to minimize unnecessary energy waste. To this end, at least one camera sensor is installed according to the area in charge of the street lamp to determine whether there is a moving object and to configure the illumination and blink of the street lamp individually. Alternatively, at least one camera sensor may be installed at a specific position to determine whether there is a moving object and to control illumination and blinking of adjacent street lamps in the same manner as in Zigbee wireless communication. In the case of street lamps, rather than blinking individually, dozens or hundreds of stored sunset time information is controlled locally by one flashing controller. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a system configuration for turning on and turning off street lights and security lights through a mobile communication network, which may be remotely lit when it is dark due to a sudden deterioration of weather other than the sunset time set by the mobile communication network at a remote control center. If not, it does not provide the function to turn off the light and lower the illuminance. 2 is a block diagram of a street lamp that provides a function of controlling the flashing or illuminance of a light bulb by using a motion detection function of a camera sensor. 3 is a diagram illustrating a wireless communication function between an image information recording function of a street light that provides a function of controlling a flashing or illuminance of a light bulb by using a motion detection function of a camera sensor and a neighboring street light.

That is, in a street light having a pole and an illumination unit, the camera sensor unit 1 is fixed to the street light and has at least one camera sensor for capturing the movement of a vehicle or a pedestrian around the street light; A motion detection means unit 2 for processing an image provided from the camera sensor unit 1 and detecting whether there is a moving object such as a vehicle and a pedestrian; When the moving object is detected by the signal of the motion detecting means 2, the street lamp is turned on or the illuminance is increased; Turn off street lights or reduce illumination when there are no moving objects; Means for generating a signal for controlling the street lamp lighting lamp 4 in the street lamp lighting and extinguishing, illuminance control determining means 3; And a street light blinking drive control means 5 for controlling the street light according to a preset blinking driving condition and time according to the sunset time information.

In this case, when the lighting control of the street light using the moving object detection sensor information of the road does not sufficiently correspond to the moving speed of the vehicle, the information of the camera sensor of the adjacent street light is necessary because the street light may operate after the vehicle passes. To this end, the camera sensor unit 1 is fixed to the street light and having at least one camera sensor for capturing the movement of the vehicle or pedestrian around the street light; A motion detection means unit 2 for processing an image provided from the camera sensor unit 1 and detecting whether there is a moving object such as a vehicle and a pedestrian; Means for acquiring, via wireless communication means, between adjacent street lamps, whether a moving object is detected in the adjacent street lamps; When the moving object is detected by the moving object information of the adjacent street lamp and the signal of the own motion detecting means 2, the street lamp is turned on or the illuminance is increased; Turn off street lights or reduce illumination when there are no moving objects; Means for generating a signal for controlling the streetlight lighting lamp 4 in the streetlight lighting and extinguishing, illuminance control determining means 3; And a street light blinking drive control means 5 for controlling the street light according to a preset blinking driving condition and time according to the sunset time information. Zigbee communication may be applied as a wireless communication means.

Alternatively, if the lighting control of the street light is used for moving object detection sensor information on the road, it may not correspond enough to the moving speed of the vehicle, so that the street light may operate after passing the vehicle. You need to control it. To this end, the camera sensor unit (1) is fixed to the street light and having at least one camera sensor for capturing the movement of the vehicle or pedestrian around the street light; A motion detection means unit 2 for processing an image provided from the camera sensor unit 1 and detecting whether there is a moving object such as a vehicle and a pedestrian; When the moving object is detected by the signal of the motion detecting means 2, the street lamp is turned on or the illuminance is increased; Turn off street lights or reduce illumination when there are no moving objects; Means for generating a signal for controlling the streetlight lighting lamp 4 in the streetlight lighting and extinguishing, illuminance control determining means 3; And means for adjusting illuminance and lighting of the adjacent transverse motion through the wireless communication means 14 between the adjacent street lamps. And a street light blinking drive control means 5 for controlling the street light according to a preset blinking driving condition and time according to the sunset time information.

In addition, by applying the function of storing the image information of the camera sensor of the street lamp like a car black box, it is possible to obtain useful image information when an event occurs. To this end, a street light having a horizontal pole and an illumination unit, comprising: a camera sensor unit (1) fixed to the street light and having one or more camera sensors for capturing the movement of a vehicle or a pedestrian around the street light; A motion detection means unit 2 for processing an image provided from the camera sensor unit 1 and detecting whether there is a moving object such as a vehicle and a pedestrian; Image information storing means 13 of a camera sensor for recording image information of the camera sensor unit 1 when a moving object is detected; When the moving object is detected by the signal of the motion detecting means 2, the street lamp is turned on or the illuminance is increased; Turn off street lights or reduce illumination when there are no moving objects; Means for generating a signal for controlling the streetlight lighting lamp 4 in the streetlight lighting and extinguishing, illuminance control determining means 3; And a street lamp blinking driving control means 5 for controlling the street lamp according to a preset blinking driving condition and time according to the sunset time information.

As such, the idea of controlling or illuminating the illumination of a light by determining the state of the main surface using a camera sensor may be used in various fields, for example, it may be applied to a home lighting and a parking lot lighting system. That is, a device for remotely turning on and off a light, comprising: a camera sensor unit (1) fixed to the light and having one or more camera sensors for capturing the movement of a user around the light; A motion detection means unit 2 for processing a video provided from the camera sensor unit 1 and detecting a specific motion operation of the user; Turning on or illuminating the lights when a motion instructing to turn on or illuminating the lights is detected by the signal of the motion detection means unit 2; If a motion is detected that instructs the light to turn off or lower the illumination, the light is configured as a means to turn off or lower the illumination. In this case, the motion to turn off the light may be set to draw an "X" with a finger, and the motion to turn on the light may be set to draw an "O" with a finger. In the following application example, a device for turning on and off the lights of a parking lot, the camera sensor unit (1) having at least one camera sensor for capturing the movement of the vehicle and the user; A motion detection means unit 2 for processing an image provided from the camera sensor unit 1 and detecting whether there is a moving object such as a vehicle and a pedestrian; When a moving object is detected by the signal of the motion detection unit 2, the corresponding lamp is turned on or the illuminance is increased; If there is no moving object, configure the lamp to turn off or lower the illumination.

In addition, when applied to home lighting, the user can sense the user's specific gesture to turn the light on or off to provide a very convenient lighting culture.
