Dual-channel disaster early-warning information receiving system and receiving method thereof

Abstract

The invention provides a dual-channel disaster early-warning information receiving system and a receiving method thereof. The system comprises a mobile phone information preprocessing module, a DAB receiver information preprocessing module, an adapter, a mobile phone and a DAB receiver. The early-warning information receiving method includes a satellite DAB receiving mode and a GPRS short message receiving mode: for an urban region, the mobile phone GPRS short message receiving mode is adopted, a mobile communication network is utilized, an early-warning region is automatically identified according to address area-owning region information, and thereby the mobile phone terminal can select and real-timely and accurately receive early-warning information; and for a rural region, the DAB receiving terminal automatically identifies an early-warning region address code according to the region parameter information of the Compass satellite, and thereby can receive the early-warning information of the remote region. By means of the dual-channel receiving mode, the invention can ensure to the max that the early-warning information of various departments at all levels can be real-timely and accurately received nationwide, thus guaranteeing the safety of lives and properties of people.

Description

technical field [0001] The invention belongs to the field of real-time data reception, in particular to the real-time reception of meteorological warning information. Background technique [0002] my country is one of the countries seriously affected by natural disasters in the world. Disasters such as typhoon, heavy rain (snow), lightning, drought, strong wind, hail, heavy fog, haze, sandstorm, high temperature heat wave, low temperature freeze damage occur from time to time, and there are many types of disasters. , wide distribution, high frequency of occurrence, and heavy losses. For most disasters, more accurate forecast information with varying timeliness can be obtained through scientific and technological means. Traditional meteorological information is mainly released through TV, newspapers, radio, SMS, Internet and other channels. These release methods require a media transfer process, and there will be a certain time delay. The public must also receive information ...

AI Technical Summary

Problems solved by technology

Traditional meteorological information is mainly released through TV, newspapers, radio, SMS, Internet and other channels. These release methods require a media transfer process, and there will be a certain time delay. The public must also receive information through these media channels. Its arrival rate will be lost to a certain extent, which will affect the effectiveness of meteorological information release

Therefore, the traditional method of issuing weather warnings cannot respond to sudden meteorological disasters in a timely manner.
