Safety System {SAFETY SYSTEM}

The present invention relates to a safety system comprising a transmission device installed in a dangerous object and a mobile receiving device carried by a protected object, and more particularly, the protected object is a dangerous area (ie, a traffic facility-traffic light area, an overpass; a dangerous facility-old). Building, hazardous building, no swimming zone; construction area-subway construction site, construction site; injury area-cliff, landslide area, etc.) The present invention relates to a safety system that promotes the safety of pedestrians by ventilating the environment by listening to the air, or by emitting light from the lamp of the mobile reception device to allow the manager or the driver to determine the location of the protection target.

For example, most pedestrian crossings are equipped with traffic lights, but drivers are not keeping their stop signal except the pedestrian crossings that are installed on large roads. In this dangerous pedestrian crossing, adults understand the traffic flow and cross it, but children with low judgment and attention often cross the road unconditionally after seeing a blue light signal.

Accordingly, in order to solve such a problem, a method of protecting a child by inducing a driver to perform defensive driving by attaching a lamp to a child's bag or a hat and entering a field of view of an automobile driver has been used.

However, the above method can be obtained due to the light emission of the lamp in the night, but the effect of the lamp is difficult to enter the driver's view during the day. Hard to get

Therefore, it is also important for the driver to know the position of the pedestrian well, but it is necessary to make the pedestrian (particularly the child) aware of the attention that can be taken care of when crossing by himself. In view of the above, some pedestrian crossings are guided and sound generation for the visually impaired.

However, the method is not for the pedestrians who need protection, such as children, but for the visually impaired. In addition, the method works only when the pedestrian crossing traffic light is a blue light, so that the target of protection in the signal waiting is still exposed to danger.

Accordingly, the present invention has been made to solve the above problems,

The purpose is to provide a safety system that allows safety to be noticed through the guidance sound generated when approaching a hazardous facility and a way to make the pedestrian's location visible to the driver and the hazardous facility manager at the same time.

In addition, an object of the present invention is to provide a safety system to prevent pedestrians and people familiar with the pedestrian to listen carefully to the guidance sound, to prevent traffic and / or safety accidents.
