[0001] The present invention relates to an integrated smart sensor device in which a motion sensor, a noise sensor, a light sensor, a vibration sensor and a positioning sensor are integrated on an interface base that is interoperable and compatible with different types of devices.

[0002] Specifically, the present invention relates to an integrated smart sensor system that uses an integrated smart sensor and a sensing algorithm to detect vehicle or human movement through a motion sensor, detect surrounding noise through a noise sensor, detect surrounding light intensity through a light sensor, detect pole impact (or tilt, earthquake, vibration), etc. through a vibration sensor (or accelerometer), and can link with different devices attached to street lamps, multi-devices mounted poles, and smart poles via a back-end interface, can link with other integrated smart sensors through ZigBee or Bluetooth communication, and can form a control system and network through data linkage with external smartphones or vehicles and Internet of Things (M2M) communication. [Background technology]

[0003] Conventionally, roadway lighting remote control systems have typically utilized wired or wireless communication systems to individually use one-way flashers, two-way flashers, illuminance sensors, motion sensors, etc. to turn roadway lighting on and off and adjust brightness.

[0004] However, unlike conventional methods, it operates independently without any linking function with other devices attached to surrounding street lamps or lampposts on the road, and has limited scalability as it only functions as a simple illumination device and for grasping operating status.

[0005] Furthermore, conventional street lights have caused complaints from surrounding residential areas and buildings due to sensor detection errors and unnecessary lighting caused by vibration of the streetlight poles.

[0006] In addition, the detection range of sensors installed in conventional street lights is within 50 degrees from the front of the sensor, which makes it difficult to optimize and reduce energy consumption due to poor detection performance and minimized lighting range.

[0007] Therefore, there is a need for functions that can guarantee interoperability, compatibility, acceptability, and scalability through the application of data-based APIs and the ability to expand the detection range of sensors to ensure road safety and save energy.

[0008] In addition, the control device must have the ability to grasp and report overloads, temperature rises and error conditions caused by abnormal current in the lighting device, and to grasp and solve problems through real-time precise status analysis and advance inspection of the main components of the lighting device, such as LEDs, converters, communications, power supplies and control devices.

[0009] Furthermore, there is an increasing need for the ability to respond immediately to emergency situations that may occur on roads, such as to ensure the safety of facilities by preventing the impact of light poles, to detect earthquakes and sinkholes, to collect new data by collecting noise emissions around roads, and to increase spatial safety by linking with personal smart devices or emergency vehicles.

[0083] FIG. 7 is a side view of an integrated smart sensor with the housing, divider and lens cover removed according to an embodiment of the invention.

[0084] Referring to FIG. 7, when the integrated smart sensor device 100 is attached to a streetlight, the lens cover 190 faces the ground, so the arrow indicating the sensing direction in the drawing can be understood to face the ground.

[0085] In detail, the first infrared sensor 1021, the second infrared sensor 1022, and the third infrared sensor 1023 are installed facing different directions from each other so as to sense different areas from each other and the sensing areas do not overlap each other.

[0086] For example, based on a state in which the integrated smart sensor device 100 is installed on the fixed arm 120, a line connecting the installation positions of the first to third infrared sensors 1021, 1022, and 1023 may form a triangle.

[0087] In detail, the second sensing direction A2 of the second infrared sensor 1022 may be a vertical direction (toward the ground). Here, the vertical direction refers to the vertical direction when the sensor board 160 is in a horizontal state. That is, it is assumed that the sensor board 160 and the ground on which the fixed pole 110 is installed are parallel to each other. Alternatively, the central axis of the second infrared sensor 1022, i.e., the direction in which the polarizing filter corresponding to the window faces, is disposed to be inclined at a predetermined angle forward from the vertical line (direction facing the center of the road from the sidewalk). The inclination angle of the second infrared sensor 1022 may be 15 degrees or less. The window or polarizing filter can be defined as a sensing surface of the infrared sensor.

[0088] Also, the first sensing direction A1 of the first infrared sensor 1021 may be inclined at a predetermined angle (e.g., 45 degrees or less) to the first side (counterclockwise) from the second sensing direction A2. That is, the sum of an angle (θ1) between the sensor substrate 160 and the central axis of the first infrared sensor 1021 and an angle between the central axis of the first infrared sensor 1021 and a vertical plane is 90 degrees.

[0089] Also, the third sensing direction A3 of the third infrared sensor 1023 may be inclined at a predetermined angle (e.g., about 45 degrees) toward the second side (clockwise) from the second sensing direction A2. That is, the sum of an angle (θ1) between the sensor substrate 160 and the central axis of the third infrared sensor 1023 and an angle between the central axis of the third infrared sensor 1023 and the vertical plane is 90 degrees.

[0090] The first to third infrared sensors 1021, 1022, and 1023 are installed so as to be inclined at a predetermined angle (θ2) (for example, 15 degrees or less) forward from the vertical direction (direction from the road shoulder to the center line of the road). The angle (θ2) can be understood as an angle between a line connecting the road shoulders and the central axis of the first infrared sensor 1021, and an angle between a line connecting the road shoulders and the central axis of the third infrared sensor 1023. Therefore, the angle between the central axis of the second infrared sensor 1022 and the central axis of the first infrared sensor 1021, and the angle between the central axis of the second infrared sensor 1022 and the central axis of the third infrared sensor 1023 can be understood as a value obtained by subtracting the angle (θ2) from 90 degrees.

[0091] As a result, the second infrared sensor 1022 can detect objects passing through an area directly below the integrated smart sensor device 100, several meters ahead facing the center of the road, and several meters behind the integrated smart sensor device 100. The first infrared sensor 1021 can detect objects passing through an area corresponding to a first side of the area detected by the second infrared sensor 1022, i.e., the left side and left front area of ​​the integrated smart sensor device 100. The third infrared sensor 1023 can detect objects passing through the right side and right front area of ​​the integrated smart sensor device 100.

[0092] FIG. 8 is a plan view of the integrated smart sensor device.

[0093] In detail, the drawing shown in FIG. 8 can be understood as showing the state when the integrated smart sensor device 100 is installed on the fixed arm 120 and the user looks up at the integrated smart sensor device 100.

[0094] Also, the second infrared sensor 1022 faces directly below and forward F. Therefore, the second infrared sensor 1022 senses the area directly below and rear B of the smart sensor device 100. The rear area refers to an area covering a pedestrian road.

[0095] The first infrared sensor 1021 covers the left side of the integrated smart sensor device 100 and the left front side including the road, and the third infrared sensor 1023 covers the right side of the integrated smart sensor device 100 and the right front side including the road.

[0096] The first to third infrared sensors 1021 to 1023 may be multi-element sensors having at least two pyroelectric elements for detecting infrared rays. Thus, a detection area detected by the infrared sensors is divided into a positive zone and a negative zone, and a number of positive zones and negative zones are alternately formed according to the number and pattern of Fresnel lenses formed on the lens cover 190. This will be described in detail below with reference to the drawings.

[0097] 9 and 10 are perspective views of a sensor bracket for fixing an infrared sensor to a sensor board according to an embodiment of the present invention.

[0098] 9 and 10, the sensor bracket 30 comprises a first mounting portion 31 to which the first infrared sensor 1021 is fixed, a second mounting portion 32 to which the second infrared sensor 1022 is fixed, and a third mounting portion 33 to which the third infrared sensor 1023 is fixed.

[0099] In detail, the second mounting part 32 is formed to be slightly inclined forward from the vertical plane, and the first and third mounting parts 31 and 33 are not only inclined at a predetermined angle from the sensor board 160 corresponding to the horizontal plane, but also inclined at a predetermined angle to the left and right sides from the second mounting part 32.

[0100] In addition, one or a plurality of sensor fixing holes 301 are formed on the surface on which the first to third infrared sensors are placed. The number of the sensor fixing holes 301 may be set to be different depending on the sensor mounting part. This is to prevent incorrect assembly when the infrared sensors mounted in the respective sensor fixing holes are different in type or specification. For example, when the same type of infrared sensor is adopted for the first infrared sensor 1021 and the third infrared sensor 1023 and only the second infrared sensor 1022 is adopted in a different type or specification of an infrared sensor, two sensor fixing holes 301 may be formed in the second mounting part 32 and three or four sensor fixing holes 301 may be formed in the first and third mounting parts 31 and 33.

[0101] A pair of fixing hooks 302 for fixing a sensor are provided on side surfaces of each of the first to third mounting parts 31 to 33. The pair of fixing hooks 302 may be formed at positions facing each other.

[0102] In addition, a bracket fixing protrusion 34 protrudes from the opposite side of the mounting surface on which the first to third infrared sensors 1021 to 1023 are placed. The bracket fixing protrusion 34 is inserted into the sensor board 160 through the bracket fixing protrusion 34.

[0103] FIG. 11 is a left bottom perspective view of a divider that constitutes an integrated smart sensor device in an embodiment of the present invention, FIG. 12 is a right bottom perspective view of the divider, and FIG. 13 is a partial longitudinal cross-sectional view of the smart sensor device.

[0104] 11 to 13, in the integrated smart sensor device 100 according to the embodiment of the present invention, the hemispherical lens cover 190 is coupled to the inner edge of the lower end of a housing 170 based on a state in which the integrated smart sensor device 100 is mounted on a fixed pole 110, and the divider 180 is disposed above the lens cover 190. Then, the sensor board 160 on which the first to third infrared sensors 1021 to 1023 are mounted is disposed above the divider 180.

[0105] More specifically, the divider 180 has a hemispherical shape similar to the shape of the lens cover 190. The divider 180 has a number of guide grooves recessed to a predetermined depth from the spherical surface, and the width of the guide grooves becomes narrower as the recession depth becomes deeper.

[0106] The multiple guide grooves include a first guide groove 181 that guides infrared rays emitted from an object passing through the first sensing area so that the infrared rays are focused on the first infrared sensor 1021, a second guide groove 182 that guides infrared rays emitted from an object passing through the second sensing area so that the infrared rays are focused on the second infrared sensor 1022, and a third guide groove 183 that guides infrared rays emitted from an object passing through the third sensing area so that the infrared rays are focused on the third infrared sensor 1023.

[0107] A first sensor hole 1811 is formed at a bottom surface of the first guide groove 181, and an infrared receiving window of the first infrared sensor 1021, or more precisely, a polarizing filter, is exposed in the first sensor hole 1811. A second sensor hole 1821 is formed at a bottom surface of the second guide groove 182, and an infrared receiving window of the second infrared sensor 1022 is exposed in the second sensor hole 1821. A third sensor hole 1831 is formed at a bottom surface of the third guide groove 183, and an infrared receiving window of the third infrared sensor 1023 is exposed in the third sensor hole 1831.

[0108] The first guide groove 181 and the third guide groove 183 extend in directions extending at a predetermined angle to the left and right sides, respectively, with respect to the second guide groove 182. The first to third guide grooves 181 to 183 form front surfaces 1812, 1822, and 1832, rear surfaces 1813, 1823, and 1833, and a pair of side surfaces 1814, 1824, and 1834, respectively.

[0109] The first to third guide grooves 181 to 183 are formed in a partitioned manner, thereby preventing adjacent infrared sensors from detecting the same object repeatedly and causing crosstalk or noise. For example, an object moving within the first detection area is detected only by the first infrared sensor 181, and is not detected by the second infrared sensor 182 or the third infrared sensor 183.

[0110] Since the divider 180 is disposed between the infrared sensors 181 to 183 and the lens cover 190, and can prevent crosstalk due to overlapping of sensing areas, a plurality of sensors can be disposed close to each other, and the integrated smart sensor device 100 can be designed to have a compact size. As a result, the manufacturing cost of the smart sensor device 100 can be reduced.

[0111] Furthermore, the separation angle or spread angle between adjacent sensors, which is set to prevent crosstalk between the adjacent sensors, can be minimized, which has the advantage of minimizing blind spots formed between adjacent sensing areas, i.e., the range of areas not sensed by the sensors.

[0112] FIG. 14 is a rear view of a lens cover provided in an integrated smart sensor device according to an embodiment of the present invention, and FIG. 15 is a view showing a sensing area sensed by an infrared sensor.

[0113] 14 and 15, the first to third sensors 1021 to 1023 each include two or more pyroelectric elements and a FET element for amplifying an infrared signal received through the polarizing filter. In this embodiment, a double element sensor having two pyroelectric elements will be described as an example.

[0114] In general, a Fresnel lens is provided in front of an infrared sensor to increase the sensing distance, sensing range and sensitivity of the sensor. In the present invention, a Fresnel lens array with different shapes is formed for each sensing area on the back side of a plastic cover formed in a round shape of a hemisphere.

[0115] The Fresnel lens extends the sensing distance of the infrared sensor to maximize its sensitivity, and prevents the sensor from being affected by external wind, as well as blocking the influence of external miscellaneous light. The focal point of the Fresnel lens array is designed to be formed on the polarizing filter of the infrared sensor.

[0116] In addition, in the structure of an infrared sensor having two pyroelectric elements, the sensing area corresponding to one Fresnel lens is divided into a positive area and a negative area. Therefore, when a moving object moves in the sensing area, it passes through the positive area and the negative area in sequence, and when infrared rays are incident on the pyroelectric element provided in the infrared sensor, a pyroelectric effect occurs in the pyroelectric element, and the infrared sensor detects the movement and moving speed of the object by detecting the voltage change at this time. The positive area and the negative area can be defined as subzones. Therefore, it can be understood that the projection plane defined in the sensing area of ​​the Fresnel lens array has subzones corresponding to the number of Fresnel lenses constituting the Fresnel lens array.

[0117] According to an embodiment of the present invention, a plurality of Fresnel lens arrays having independent sensing areas are provided on the rear surface of the lens cover 190. The plurality of Fresnel lens arrays may be defined as a collection of a plurality of Fresnel lenses, and Fresnel lenses having different shapes are provided for each sensing area. The plurality of Fresnel lenses are formed on the rear surface of the lens cover 190.

[0118] In detail, the plurality of Fresnel lens arrays may include a first lens array 191 for allowing infrared rays to be incident on the first infrared sensor 1021, a second lens array 192 for allowing infrared rays to be incident on the second infrared sensor 1022, and a third lens array 193 for allowing infrared rays to be incident on the third infrared sensor 1023. The second lens array 192 is divided into a front lens array 1921 and a lower lens array 1922.

[0119] Based on the infrared sensor assembly, specifically, on a point of the lens cover 190 corresponding to a position immediately in front of the sensor bracket 30, the first lens array 191 is formed on the left side, the second lens array 192 is formed in the center, and the third lens array 193 is formed on the right side.

[0120] The first lens array 191 and the third lens array 193 are provided in a symmetrical shape at positions symmetrical to each other with respect to a line that bisects the lens cover 190. The shapes of the first and third lens arrays 191 and 193 may be designed to be different from the lens shape of the second lens array 192, and the first and third infrared sensors 1021 and 1023 may detect different objects from the second infrared sensor 1022. For this reason, the second infrared sensor 1022 may have a different specification from the first and third infrared sensors 1021 and 1023.

[0121] The first and third lens arrays 191 and 193 may have a structure in which a number of Fresnel lenses, each having a long and curved rectangular shape, are arranged in the radial direction of the lens cover 190 as shown in the figure.

[0122] The second lens array 192 may have a dimple structure in which a number of circular Fresnel lenses are arranged adjacent to each other, and the diameter of the Fresnel lenses constituting the front lens array 1921 and the separation distance between adjacent lenses may be designed to be different from the diameter of the Fresnel lenses constituting the lower lens array 1922 and the separation distance between adjacent lenses.

[0123] As an example, by designing the size of the Fresnel lenses constituting the front lens array 1922 and the separation distance between adjacent Fresnel lenses to be larger than the size of the Fresnel lenses constituting the rear lens array 1922 and the separation distance between adjacent Fresnel lenses, the sensing area covered by the front lens array 192 can be expanded from the sidewalk toward the center of the road.

[0124] The positions and number of the Fresnel lens arrays may correspond to the number of infrared sensors provided in the integrated smart sensor device 100 and the directions in which the polarizing filters of the infrared sensors face.

[0125] In addition, based on the integrated smart sensor device 100, a projection surface defined as a left sensing area 710 is formed on the left ground, a projection surface defined as a central sensing area 720 is formed on the center ground, and a projection surface defined as a right sensing area 710 is formed on the right ground. In addition, a projection surface defined as a front sensing area 7201 and a projection surface defined as a lower sensing area 7202 are divided and formed in the central sensing area 720.

[0126] The positions at which these sensing regions are formed and the sensing areas are determined by the positions at which the lens arrays 191 to 193 are formed and the sizes and shapes of the Fresnel lenses that form each of the lens arrays.

[0127] Specifically, the left detection area 710 and the right detection area 730 are projected onto the road S to detect the movement of bicycles and automobiles which are moving at relatively high speeds, the front detection area 7201 of the central detection area 720 is projected onto the road S to detect the movement of automobiles, and the lower detection area 7201 is projected onto the sidewalk P to detect the movement of people or pets walking or bicycles which are moving at relatively slow speeds.

[0128] Meanwhile, as shown in Fig. 7, each sensing area is divided into a plurality of divided areas. The motion sensor 102 can determine the type of an object based on the size and speed of the object when passing through each divided area. The plurality of divided areas includes a plurality of positive areas and negative areas as described above.

[0129] For example, the left sensing area 710 is divided into a pattern in which a first division area 711 (positive area) and a second division area 712 (negative area) are repeated, and the right sensing area 730 is divided into a pattern in which a seventh division area 731 (positive area) and an eighth division area 732 (negative area) are repeated.

[0130] Meanwhile, the central sensing area 720 can include divided areas in which different patterns are repeated since it simultaneously senses the road S and the sidewalk P (or bicycle path). For example, the forward sensing area 7201 sensing the road S is divided into a pattern in which the third divided area 721 (positive area) and the fourth divided area 722 (negative area) are repeated. And the lower sensing area 7202 sensing the sidewalk P is divided into a pattern in which the fifth divided area 723 (positive area) and the sixth divided area 724 (negative area) are repeated.

[0131] Meanwhile, the size of each of the fifth and sixth divided regions 723 and 724, which are regions detecting the sidewalk P (or bicycle path), may be smaller than the size of the third and fourth divided regions 721 and 722 in the region detecting the road. That is, the size of the divided regions in the region detecting a slow-moving object is formed small, and the size of the divided regions in the region detecting a fast-moving object is formed relatively large. Thus, in the region detecting the sidewalk (or bicycle path), humans and bicycles move slower than vehicles traveling on the road, so the divided regions can be small in size.

[0132] The control unit 109 may obtain moving object type information based on object motion information sensed in each sensing area corresponding to the first infrared sensor 1021, the second infrared sensor 1022, and the third infrared sensor 1023 defined as the motion sensor 102. The object motion information may include object size information and object speed information, and the object types may be classified into vehicles, bicycles, humans, and pets.

[0133] The control unit 107 can transmit the acquired object movement information and object type information to the control server 200 via the communication unit 101 .

[0134] Thus, the control server 200 can provide the control device 300 with information regarding the type of each object moving around the lighting device 130 and the size and speed of each object.

[0135] According to the present invention, the divider 180 is provided between the infrared sensor and the lens cover 190, thereby minimizing the area of ​​the non-detectable zone or blind spot formed between the left sensing area 710 (or the right sensing area 730) and the central sensing area 720. Furthermore, depending on the arrangement of the lens arrays 191 to 193 formed on the lens cover 190 and the shapes and sizes of the Fresnel lenses constituting each lens array, target objects with different speeds can be accurately detected.

[0136] The present invention described above can be embodied as computer readable code on a medium having a program recorded thereon. The computer readable medium includes all kinds of recording devices in which data readable by a computer system is stored. Examples of computer readable media include HDD (Hard Disk Drive), SSD (Solid State Disk), SDD (Silicon Disk Drive), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc.
