Self-powered wireless duplex emergency broadcasting system

Abstract

The invention discloses a self-powered wireless duplex emergency broadcasting system and belongs to the technical field of broadcasting, comprising a solar cell panel and a mobile terminal. The electrical output of the solar cell panel is connected with a storage cell. The electrical output of a central processing unit is connected with a voice broadcasting library. The electrical input of the central processing unit is connected with a base station. The electrical output of the base station is connected with a broadcasting terminal and the mobile terminal. The electrical input of the centralprocessing unit is connected with a network terminal. The electrical output of the central processing unit is connected with an emergency switch. The electrical output of the emergency switch is connected with an emergency base station. The electrical output of the emergency base station is connected with the broadcasting terminal and the mobile terminal. The electrical output of the central processing unit is connected with the emergency base station. The electrical output of an emergency network terminal is connected with the central processing unit. According to the system, the duplex emergency intercom under the emergency condition is also not influenced, moreover, a voice can be identified, the content needing to be broadcasted is judged, and when a danger or disaster comes, the normal work of the system can be ensured.

Problems solved by technology

[0006] Similarly, in the traditional emergency broadcasting system, the commander needs to enter the broadcasting room to turn on the broadcasting equipment before broadcasting. Due to the low efficiency of this emergency broadcasting system, it is easy to delay the best time to deal with emergencies. The emergency broadcast system is remotely controlled. When the emergency broadcast system is remotely controlled, even if the commander is far away from the incident, the emergency broadcast system can be activated as soon as the incident occurs, so as to carry out emergency command and information release. However, such a broadcast system It can only be controlled by the command personnel. When an emergency occurs, the command personnel often cannot know it immediately. At the same time, when the disaster strikes, the traditional broadcasting system often cannot work normally due to power failure, network interruption and other reasons. And often when a disaster strikes, due to the interruption of communication, broadcasting is particularly important
