The vehicle detection unit 100 may be installed in the vicinity of the surveillance area A so as to detect the vehicle B entering the intersection as the surveillance area A. The number may be a number of intersections of the intersections, Width, and the like. The vehicle detection unit 100 includes a camera module 110 that photographs an observation area to detect a vehicle object, a vehicle recognition module 120 that recognizes the vehicle from the captured image captured by the camera module 110, 130). The vehicle recognition module 120 analyzes the image photographed by the camera module 110 and transmits the vehicle recognition information to the main notification device 200 when the vehicle is found. Here, the camera module 110 may include a thermal imaging camera, and thus it is possible to analyze whether or not the vehicle in the stopped state is in the ON state or in the OFF state, by analyzing the thermography image. In addition, the acoustic sensor 130 can determine whether the vehicle is in a stopped state or an idling state by measuring the vehicle noise to determine whether the vehicle is a vehicle.

In the embodiment of the present invention, since the surveillance area A is an intersection, the vehicle detection unit 100 includes four first to fourth vehicle detection units 101, 102, 103, and 104 for monitoring four roads connected to an intersection Let's take an example as an example.

The main notification apparatus 200 includes an audio signal output unit 210 for outputting an audio signal, a light output unit 220 for outputting vehicle appearance notification information as light, A storage unit 240, a communication unit 250, a power supply unit 260, and a control unit 270. The environment detection unit 230 includes a storage unit 240,

The audio signal output unit 210 may include a speaker installed in the main body 201 of the main notification device 200. And the control unit 270 controls the audio signal output unit 210 to output a vehicle appearance notification signal as an audio signal. It is preferable that the audio signal outputted here is a fart sound that can induce an immediate reaction to pedestrians walking on the periphery, in particular, children, and more preferably, a fart sound of an uncle of ' It is good. When the vehicle B arriving at the surveillance area A is detected as described above, if the fart sound of the 'uncle' is outputted through the audio signal output unit 210, the surrounding pedestrian immediately reacts to the surrounding situation So that a safety accident caused by the appearance of a vehicle in a blind spot can be prevented.

Also, the audio signal output through the audio signal output unit 210 may be output in various forms according to the environment of the monitoring area A. For example, it may be controlled to increase the output size in a noisy or rainy ambient environment, or to reduce or normally output the output in a clear, noisy environment.

Also, the fart sound to be output may be differently output according to the weather condition, and for example, it can be controlled to output a loud sound on a clear day and a heavy sound on a cloudy day.

The light output unit 220 may include at least one beacon provided in the apparatus main body 201 for outputting a signal indicating the appearance of a vehicle as light. The light intensity of the beacon can be variously selected and the driving of the beacon is controlled by the controller 270. It is preferable that the light output unit 220 is controlled to be repeatedly blinked so as to give a stimulus to the pedestrian so as to be alert.

The environment detecting unit 230 is for detecting an environmental condition of the monitoring area A. The environment detecting unit 230 may include an acoustic sensor 231, a temperature sensor 232, a humidity sensor 233, and an illuminance sensor 234.

The sound sensor 231 senses sounds in the monitoring area A and provides the sensed information to the controller 270. In other words, it can detect the surrounding noise, detect raindrops and wind sounds on rainy days, and can detect the sound of the children. Accordingly, the control unit 270 determines the acoustic information sensed by the acoustic sensor 231 and confirms the size of the surrounding noise, the weather condition, the presence of pedestrians (particularly, children) and the like, And selectively output according to a look-up table stored in the storage unit 240. [0033] FIG. For example, when the controller 270 is installed in front of the school, the control unit 270 recognizes the patterns of the children's sounds and determines that the children are nearby, and outputs a warning light from the light output unit 220 to the audible sound of children And the fart sound is outputted through the audio signal output unit 210, so that the child can awaken the awareness so as to observe the attention.

The temperature sensor 232 is for measuring temperature, and may be installed to supplementarily acquire a weather condition or the like.

The humidity sensor 233 is provided to measure the ambient humidity to confirm whether it is raining or a misty day. That is, the controller 270 receives the humidity measurement information sensed by the humidity sensor 233, comprehensively analyzes the current weather state with the sensed information of the acoustic sensor 231 and the temperature sensor 232, It is possible to judge accurately.

The illuminance sensor 234 measures the illuminance of the surrounding illuminance and transmits the illuminance to the controller 270 so that the controller 270 can receive information that can more specifically determine whether the illuminant is a cloudy day , Accurate environmental judgment becomes possible.

The audio signal data to be output through the audio signal output unit 210 may be stored in the storage unit 240 in a form of a so-called lookup table, The information can also be stored in the form of a look-up table matching the environmental conditions.

Accordingly, the control unit 270 analyzes and determines the detection data detected by the environment detecting unit 230 to check the environmental condition, receives the output data corresponding to the checked environmental condition from the storage unit 240, As shown in FIG.

The communication unit 250 transmits and receives mutual information to and from the vehicle detection unit 100 and the assistant notification device 300 through a wired or wireless communication network and the reception information is provided to the control unit 270.

In addition, the communication unit 250 can transmit information to the control room 510 or the manager terminal 520 via a wired / wireless communication network.

The power supply unit 260 is for supplying power to the main notification device 250 and may include a rechargeable battery for recharging the power supplied from the external power supply. It can be used by itself and supplemented with external power supply.

The controller 270 controls the audio signal output unit 210 and the light output unit 210 to receive the information about the vehicle B entering the monitoring area A from the vehicle detection unit 100, 220 to output vehicle presence notification information. In particular, the control unit 270 controls the output unit 230 to output an output signal corresponding to the environmental condition-specific output data stored in the storage unit 240 on the basis of the environmental information detected by the environment detecting unit 230, So-called customized announcement information can be provided by controlling the output data differently depending on the presence or absence of noise, the size of noise, presence of children, and the like.

In addition, the main notification device 200 preferably further includes a photographing module 280. The photographing module 280 may include a surveillance camera installed to photograph the surveillance area A and a pan / tilting driver that drives the surveillance camera to pan / tilt. The photographing module 280 may be installed in the apparatus main body 201 or may be installed in a separate pole (a pole, a lamppost, etc.). The photographing module 280 is driven and controlled by the control unit 270, and the photographed photographed image is stored and managed in the storage unit 240. That is, when receiving the vehicle detection information from the vehicle detecting unit 100, the control unit 270 drives the photographing module 280 from that time to photograph the monitoring area A, 240). Therefore, the control unit 270 drives the photographing module 280 only when the vehicle B enters the surveillance area A, so as to photograph the surveillance area A, thereby reducing the maintenance cost, (B) records and manages safety incidents that may occur when entering the monitoring area (A), so that they can be used as evidence materials in the future.

As shown in FIG. 4, the auxiliary notification device 300 may be connected to the main notification device 200 through a signal cable as shown in FIG. 4 and FIG. Can be delivered. The auxiliary notification device 300 includes a base 310 and a cover 320 coupled to the base 310 and a plurality of lights 331, 332, 333, and 334 installed in the cover 320. The plurality of lights 331, 332, 333, and 334 are independently driven and controlled by the control unit 270 of the main notification device 200.

That is, when the control unit 270 finds the vehicle B entering the intersection through the fourth vehicle detecting unit 104 among a plurality of roads as shown in FIG. 2, the control unit 270 enters the vehicle B in a rectangular area And controls the first and third lights 331 and 333 to be turned on and off in red so as to give a warning signal to a pedestrian or a driver of the vehicle. Therefore, the fact that the vehicle B is approaching the crossing point of the intersection can be recognized by the pedestrian and the vehicle driver located in the blind spot. The plurality of lights 331, 332, 333, and 334 are normally blinking in yellow or the like. When it is confirmed that the vehicle enters the intersection, the lights are changed to red or the like and blinking is performed. More preferably, the blinking operation is performed more quickly than usual It is preferable to maximize the warning signal notification effect.

The external speaker 400 may be further provided adjacent to the vehicle detection unit 100. The external speaker 400 may be controlled by the control unit 270 to stop the vehicle for a long time, And can output a message.

Hereinafter, a method of informing a vehicle passage using the vehicle passing detection system according to the embodiment of the present invention having the above-described configuration will be described in detail.

Referring to FIG. 1 to FIG. 6, the normal mode in which the lights 331, 332, 333, and 334 of the auxiliary notification device 300 are blinkingly operated in a yellow color or the like is performed normally (S10).

When the vehicle detection unit 100 detects the vehicle B during the normal mode operation (S11), the main notification device 200 and the auxiliary notification device 300 are controlled to output a signal indicating the appearance of the vehicle (S12). That is, in the main notification device 200, as described in detail above, when the vehicle detection signal from the vehicle detection unit 100 is transmitted to the control unit 270 in step S12, the control unit 270 controls the environment detection unit And outputs the notification signal according to the environment through the audio signal output unit 210. The light detection unit 220 detects the fart sound of the ' It is possible to output information to the pedestrian or the driver by outputting light in various output modes.

Here, the notification signal output step S12 is performed for a predetermined set time until it is confirmed that the vehicle is out of the monitoring area A. When the vehicle continuously enters, The operation time of step S12 can be extended.

On the other hand, it is determined whether the operation time (notification signal output time) of the notification signal output step S12 exceeds one set time (N seconds) (S13). If the operation time exceeds the set time, It is determined whether the temperature change state of the vehicle is continued for a predetermined time or longer based on the detection information from the vehicle detection unit 100 (S14).

If the temperature change state occurs within the reference time in step S14, the control unit 270 determines that the vehicle is stopped while the vehicle is not moving and the vehicle is stopped. Thus, a warning message about illegal parking or occupancy is transmitted to the external speaker 400 Or through its own audio signal output unit 210 (S15).

If it is determined in step S14 that the temperature change state does not occur within the reference time, the controller 270 determines whether the vehicle is in idling in the stop state, And detects whether sound is generated (S16).

If it is determined in step S16 that the vehicle sound is not generated, it is determined that the vehicle is stopped in the off state and the step S15 is performed. On the contrary, if it is determined that the vehicle sound is generated, And outputs a CO2 generation alarm signal through the output unit 210 (S17).

If it is determined that the sound of the vehicle continues for at least the reference time after the step S17, the step S15 is performed if the sound is not continued for more than the reference time. Otherwise, if the sound exceeds the reference time, (520) or the manager terminal (520) so as to be able to take subsequent actions (S19).

As described above, according to the pedestrian-friendly safety alert device and method according to the embodiment of the present invention, when a vehicle enters a surveillance area A having a blind spot such as an intersection or a curve, To tell the emergence of the vehicle, audibly to tell the sound of a fart of 'Uncle' and visually light the light to inform you can be easily recognized.

Therefore, it is possible to prevent a safety accident caused by carelessness or a sudden appearance of a vehicle.

In addition, it is possible to monitor a long-time stopping state or an idling state of the vehicle, and to follow-up not only a warning about an occupied vehicle or an idling vehicle for a long time.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
