Description

Wireless broadcasting device for moving objects based on 4G mobile communication {WIRELESS BROADCASTING APPARATUS FOR MOVING OBJECTS BASED IN 4TH GENERATION MOBILE COMMUNICATION}

The present invention relates to a wireless broadcasting device for a mobile object based on 4th Generation Mobile Communication (4G).

In general, in places where a large number of tourists gather, such as amusement parks, coastal areas, and national parks, there are general announcements such as opening and closing hours, real-time weather information, facility use information, evacuation tips in case of disaster, or disaster situations such as fire. Broadcasting facilities that can perform evacuation broadcasts in case of occurrence have been established.

Conventional broadcasting facilities are systems that install speakers in certain areas near facilities mainly used by users or along roads to broadcast general announcements or evacuation broadcasts in case of emergency at a management office, etc., and a network connection method for broadcasting transmission, There is only a difference in the speaker's power supply method and the structure of components, and it belongs to a similar technology conceptually in that it provides announcements by installing speakers on streetlights or general posts.

However, in the conventional broadcasting facility, there is a problem in that there is a limitation according to the speaker installation cost in order to perform announcements over a wide area, and a lot of manpower and cost are required to check, maintain, and manage wired networks and speakers.

In particular, in the event of a disaster, such as a fire, announcements should be effectively conducted in places where there are few users intensively in a specific danger area.Since speakers are fixedly installed only in specific places in conventional broadcasting facilities, the evacuation induction effect is halved. As a result, there is a problem in that a small number of users are isolated in a certain place, and thus, disaster response cannot be quickly implemented.

In addition, if a machine breakdown, error, or network disconnection occurs due to a disaster, announcements may not be sent to some areas. To solve this problem, workers need to check all the speakers and have a lot of manpower and time. And because of the need for cost, there is a problem that a lot of difficulties are involved in improving the efficiency of announcements, reducing installation costs, and maintaining.

In addition, conventional broadcasting facilities require installation of speakers, etc. using buoys in the case of the sea more than a certain distance from the coast, and broadcasting facilities including speakers in places where work is difficult such as the sea or inaccessible places such as deep valleys. It is not only very difficult to construct, but also there is a problem with a large risk of loss.
