, If you want to talk about this emergency broadcast, many people may not quite understand the exact meaning. In fact, it is a means to quickly convey important information to people in specific areas through the broadcast system when encountering emergencies such as natural disasters and public safety events. For example, if a fire occurs, you can quickly tell everyone how to evacuate through emergency broadcasts.
This emergency broadcast system contains many components.
1. Broadcast host : This is a core key component. It shoulders the heavy responsibility, and is responsible for storing a large amount of broadcast content and sending broadcast commands. The broadcast content must contain some of it; for example, how to deal with it in disaster situations.
2. Power amplifier This object is mainly used to increase the intensity of the broadcast signal; this can ensure that the sound is loud enough to be heard in the entire area that needs to be covered. For example, if the power amplifier is not strong on a commercial building, the signal becomes weak, the person in the corner may not hear the radio and it is easy to get into trouble. This is very difficult.
3. Speaker or speaker : This is the important object we actually receive broadcast messages. They are distributed in all places to ensure that there are no blind spots in the comprehensive area to cover the area.
Using emergency broadcasts is a lot and some are very important. It is very important for individuals to ensure that individuals can know how to protect themselves; for a large group like the community, it is conducive to emergency dispatch and organizational evacuation; and the good impact in safety and social effects is greatly reflected.
Here are some common questions to talk about.
Q: How can I get some places with strongly enclosed basements and corridors where emergency broadcast signals cannot be covered in certain special areas?
Answer: At this time, a higher power amplifier can be set up, and wireless emergency speakers can be installed to assist signal transmission to enhance transmission performance. If it is really not good, you can also set multiple repeat broadcasts to ensure a certain signal coverage. For example, in the underground morgue of the hospital, you have to find ways to ensure that there is a signal to prevent people from hearing the radio commands in special scenarios; otherwise, it will be particularly prone to accidents.
Q: What should I do if a device failure delays the report of an emergency? ?
The answer is normal. Regular equipment should be strictly inspected to ensure normal status; set up backup power. For example, there are some rescue equipment in the hospital that has backups, and emergency broadcasts also need to be guaranteed to be completely unfailed at all times. In addition, multiple sets of alarm notification equipment are set up to prevent the sudden suspension of the equipment when it is important. If it is not available online, it will not be used.
In general, the thing about Emergency Radio is definitely very special and very important. If emergency messages cannot be transmitted in a timely and effective manner during the chaos, the society must not mess around by effectively using this advanced emergency broadcasting method, and can quickly spread emergency and clear guidance information so that the public can protect their lives in the correct and standardized ways. In fact, it is indeed a measure that is very beneficial to the stability of human society and the welfare of life; it should be vigorously promoted and used.
