Problems solved by technology
[0005] Although the above-mentioned utility model has improved the implementation of the disaster plan in other aspects, its disaster plan alarm method is actually the same as the traditional disaster plan alarm method, and the connection with the disaster place and the broadcasting method of the disaster plan alarm information still exist. Same disadvantages as current technology

Embodiment Construction
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0037] The present invention provides a pre-plan type disaster alarm method for directional and individualized content transmission based on carrier frequency carrier, the steps are as follows:
[0038] 1) According to different disaster situations, different physical locations, and different groups of people, make individualized formulations to form targeted pre-plan alarm content information; the targeted pre-plan alarm content information includes audio alarm information and targeted disaster avoidance guidance audio Information and / or video alarm information, targeted disaster avoidance guidance pictures and video information;
[0039] 2) The disaster alarm content transmitting device broadcasts various disaster-specific pre-plan alarm content information; the so-called pre-plan specifies different and targeted alarm and disaster avoidance...

The present invention relates to a disaster alarm method and a system for carrying out directional content transmission based on a carrier frequency and a carrier wave. The system comprises a directional disaster alarm content transmitting device, disaster alarm devices receiving specifically and an alarm processing system. The disaster alarm content transmitting device sends the disaster alarm information and the disaster avoiding guiding information needed by the respective or grouped disaster alarm devices to the coverage range of the disaster alarm content transmitting device in a broadcast manner. When a disaster alarm is needed, the alarm processing system broadcasts the activation information via a radio station or in a satellite communication manner, and the disaster alarm devices receive all the activation information. After receiving the activation information, the disaster alarm devices compare whether the existing disaster alarm information and the disaster avoiding guiding information is activated by the activation information; if no, the activation information is ignored; if yes, the disaster alarm information and the disaster avoiding guiding information is decrypted, and the disaster alarm information and the disaster avoiding guiding information in allusion to the positions of the alarm devices and the correlated crowds is played.
Description
technical field [0001] The invention relates to the field of disaster preplan alarms, and more specifically, to a disaster alarm method and system for directional content transmission based on carrier frequency carriers. Background technique [0002] Traditional alarm systems can only prompt what kind of alarms have occurred, such as air raids, tsunamis, earthquakes, etc., but cannot guide people on what to do. There are two main reasons: 1. When a disaster occurs, power and communication are often interrupted, and the targeted equipment often fails to give an alarm prompt; 2. When a disaster occurs, the only available communication methods are radio stations and satellite communications. The bandwidth of the two methods is very small, and the limited bandwidth cannot give different disaster avoidance instructions to different places and different groups of people.
