In more detail, the object detecting unit 130 may include at least one of an ultrasonic sensor sensing the sensing object 10 and an acoustic sensing sensor sensing noise generated by a vehicle corresponding to the sensing object 10. The sensor unit 132 may include a sensor.

That is, the object detecting unit 130 may include a plurality of (eg, two) ultrasonic sensors as the sensor unit 132 to detect a person or a vehicle as the sensing object 10, wherein each ultrasonic sensor may be It is preferable to be installed in a spaced direction so that an error does not occur due to interference between each other.

Alternatively, the object detecting unit 130 may include a plurality of (eg, two) sound detecting sensors as the sensor unit 132 to detect the vehicle as the sensing object 10, wherein each sound detecting sensor may be The microphone for receiving sound, that is, the microphone 1 of the acoustic sensor 1 and the microphone 2 of the acoustic sensor 2 are preferably spaced apart from each other by a specific angle so that an error does not occur due to interference between each other.

And, as described above, in order to detect a person or a vehicle as the sensing object 10 as a plurality of (eg, two) ultrasonic sensors as the sensor unit 132, the object detecting unit 130 includes an ultrasonic sensor. Presence determination unit 136 to determine whether the sensing object 10 exists within the entry range, and if the sensing object 10 exists within the entry range, a motion estimation algorithm predefined based on the detection by the ultrasonic sensor It may include a motion estimation unit 138 for estimating at least one of the movement direction and the movement speed with respect to the sensing object 10 by using.

Here, the object existence determining unit 136 may determine whether there is a sensing object 10 present in the entry range through a plurality of ultrasonic sensors provided as the sensor unit 132 (eg, two). . Herein, the entry range may mean a preset detectable range in which a plurality of ultrasonic sensors (eg, two) provided as the sensor unit 132 can detect the sensing object 10, or a street lamp device ( It may mean a preset lighting area that the street lamp lighting lit in 100) affects.

The motion estimation unit 138 detects the detection object 10 using a motion estimation algorithm defined based on detection by the ultrasonic sensor when the detection object 10 exists within the entry range as a result of the determination of the object existence determining unit 136. Probability estimation information is generated by estimating at least one of the direction of motion and the speed of the motion with respect to 10).

For example, the motion estimator 138 may be configured such that the first ultrasonic sensor of one of the plurality of ultrasonic sensors (for example, two) detects the first sensing object 10 and the other ultrasonic sensor first detects the object ( 10) Counting the time until the moment of recognition, and the distance that the two ultrasonic sensors recognize the vehicle for the first time to determine the moving distance of the vehicle to estimate the movement speed and to estimate the direction of movement.

Thus, in order to detect a person or a vehicle as the sensing object 10 as described above, when the plurality of ultrasonic sensors (for example, two) are provided as the sensor unit 132, the object detecting unit 130 may include a sensing object ( The controller 140 may provide the detection result including the presence information and the motion estimation information that determine whether the 10) exists within the entry range.

On the other hand, as described above, in order to detect the vehicle as the sensing object 10, a plurality of (e.g., two) sound detection sensors as the sensor unit 132, the object detection unit 130, the predetermined reference noise By detecting the reference noise in the state in which the sensing object 10 does not exist in the entry range through the acoustic sensor at each detection cycle, calculate the average noise value of the target object and set the reference noise value based on the calculated average noise value.

Here, the reference setting unit 134 does not exist in the entry range through the plurality of sound detection sensors (for example, two) provided as the sensor unit 132 for each preset reference noise detection period. The operation of detecting the reference noise in the absence of state is repeated. Accordingly, the reference setting unit 134 calculates these reference noise average values by calculating an average of the reference noise values repeatedly obtained for each noise detection cycle. The reference setting unit 134 may set the reference noise value based on the calculated average noise average value.

At this time, if the reference setting unit 134 reaches the preset reference noise update period, the reference noise setting operation may be repeated by repeating the above-described reference noise detection operation and averaging to secure the accuracy of the reference noise setting. have.

The object presence determining unit 136 may determine whether there is a sensing object 10 present within an entry range through a plurality of acoustic sensors (eg, two) provided as the sensor unit 132.

For example, the object existence determining unit 136 detects and amplifies sound through a plurality of acoustic sensors (eg, two) provided as the sensor unit 132, and then detects noise generated when the vehicle moves. The wind, rain, voice, etc., except for the noise is judged by using the BandPass Filter to extract only the noise of the vehicle. The object presence determining unit 136 converts the extracted vehicle noise into a smooth waveform through the half-wave rectifier circuit and the LowPass Filter. Therefore, in order to determine the presence of the sensing object 10, that is, the vehicle, a certain value of the waveform which is finally output after the two acoustic sensors are detected is set as a threshold, and when it is lower than the threshold, it is recognized as noise and is higher than the threshold. If the value persists for more than a certain time, the noise of the vehicle may be determined to determine whether the sensing object 10, that is, the vehicle is present.

Here, the entry range may mean a preset detectable range in which a plurality of acoustic sensors (eg, two) provided as the sensor unit 132 can detect the sensing object 10, or a street lamp device. It may mean a predetermined lighting area that the street lamp lighting is turned on at 100.

The motion estimation unit 138 detects the object to be detected using a motion estimation algorithm predefined based on the detection by the acoustic sensor, when the detection object 10 exists within the entry range as a result of the determination of the object existence determining unit 136. Probability estimation information is generated by estimating at least one of the movement direction and the movement speed with respect to (10).

For example, the motion estimation unit 138 may include a threshold value of the microphone 1 corresponding to the acoustic sensor 1 among the plurality of acoustic sensors (eg, two) from the threshold of the microphone 2 corresponding to the acoustic sensor 2. The time difference may be used to estimate the moving direction and the moving speed of the vehicle.

Thus, as described above, in order to detect the noise of the vehicle as the sensing object 10, when the plurality of sound sensors (eg, two) are provided as the sensor unit 132, the object detecting unit 130 may detect the object. The controller 140 may provide the detection result including the presence information and the motion estimation information that determine whether the 10 exists within the entry range.

In this case, the controller 140 may control the streetlight driver 110 to adjust the brightness or the color of the streetlight lighting in response to the movement speed of the sensing object 10 based on the motion estimation information in the detection result.

For example, the controller 140 may reduce psychological stability when the movement speed of the sensing object 10 is lower than the preset speed limit in response to the movement speed of the sensing object 10 based on the motion estimation information in the sensing result. By controlling the streetlight driver 110 to turn on the street lamp (not shown) to the blue system to induce the driver to reduce the psychological burden, and if the higher than the speed limit by step by step increases the red street light ( By controlling the streetlight driver 110 to turn on (not shown), it is possible to induce the driver to be alert to speeding to prevent traffic accidents.

Meanwhile, as described above, the controller 140 may receive the lighting control information from the other streetlight device 100 'in the same way as the controller 140 provides the lighting control information to the other streetlight device 100'.
