Description

TECHNICAL FIELD [0001] The present invention relates to a smart advertising video output device for outdoor use,

The present invention relates to a smart advertisement image outputting apparatus for an outdoor unit, and more particularly, to a smart advertisement image outputting apparatus for an outdoor unit, which is installed outdoors such as a crosswalk or a streetlight telephone pole and can transmit an image including an advertisement or a public interest phrase to a pedestrian or a vehicle driver And a smart advertisement image output device for outdoor use.

Generally, a roadway is provided with a pedestrian crossing at predetermined intervals so that a pedestrian can cross the roadway, a pedestrian can be safely crossed by using a pedestrian crossing on a road provided with the pedestrian crossing, Traffic lights that indicate traffic conditions in color are installed so that the vehicle can be operated safely.

In this way, a traffic light installed on a pedestrian crossing usually means a signal for stopping without walking when a red light is on, and a signal for a pedestrian to walk on a pedestrian crossing when a green light is on.

Therefore, when the red light of a traffic light is turned on, a lot of pedestrians waiting at the both ends of the crosswalk are waiting for the green light to turn on to cross the roadway through the crosswalk, and the green light of the traffic light is turned on When pedestrians are waiting in India at both ends of the crosswalk, they walk across the crosswalk and cross the roadway.

On the other hand, drivers who drive the vehicle on the road watch the traffic light on the road where the crosswalk is provided, and when the red light of the traffic light on the road is lit, the vehicle is stopped on the stopwatch provided on both sides of the crosswalk Pedestrians can safely cross the roadway through the crosswalk, and if the traffic lights are lit green, they will cross the crosswalk.

Around the crosswalk, there are many pedestrians or pedestrians crossing the pedestrian crossing, or waiting in India, or pedestrians crossing the pedestrian crossing, many vehicles stop at the pedestrian crossing stop line. At this time, most of the pedestrians and drivers I wasted my time indefinitely.

Therefore, in order to expose the advertisement to the pedestrian waiting on the pedestrian crossing, a method of exposing the advertisement to the pedestrian or the driver by putting the advertisement phrase in the pedestrian crossing near the pedestrian crosswalk has been developed and used. However, When finished, new paint is applied to put new advertisement texts, and there is a problem that replacement of advertisement texts is troublesome and the advertising expression method to be transmitted to the public is limited to pictures or characters, .

Thus, in recent years, an advertising system such as a beam projector has been used to develop an advertisement system in which advertisements or advertising texts are transmitted to pedestrians or drivers by crossing footage or India with images containing various advertisements or public utterances However, in the case of an advertising image output device such as the above-mentioned beam projector, when installed outdoors such as a pedestrian crossing, a streetlight, or a telephone pole, there is a possibility that external environmental factors such as rain, wind, snow, humidity, There is a problem that a failure or malfunction occurs due to a physical environment element, so that there are many problems to be applied to an advertisement system installed outdoors, and thus it is not used.

For example, the control unit 150 may include a temperature sensing sensor 151 and a control unit 152.

The temperature sensor 151 is disposed inside the case 110 to detect a temperature inside the case 110.

The control unit 152 compares the temperature inside the case 110 sensed by the temperature sensor 151 with the predetermined temperature and determines that the temperature inside the case 110 is higher than the pre- Thereby stopping the operation of the battery 120.

Meanwhile, the controller 152 may be connected to the outdoor air circulation fan 133 and the indoor air circulation fan 134.

Accordingly, when it is determined by the controller 152 that the temperature inside the case 110 is higher than the pre-set temperature, the rotation speed of the outside air circulation fan 133 and the circulation circulation fan 134 is set to be equal to or higher than the set rotation speed It is possible to control the outside air circulation fan 133 and the inside air circulation fan 134. When it is determined that the temperature inside the case 110 is lower than the preset temperature, the outside air circulation fan 133 and the inside air circulation fan 134 The circulation fan 133 and the circulation fan 134 can be controlled such that the rotation speed of the circulation fan 133 is equal to or lower than the set rotation speed.
