A natural disaster automatic early warning system and its realization method

Abstract

The invention discloses a natural disaster automatic early warning system and a realization method thereof. Defects that according to the conventional natural disaster early warning system, the early warning is not in time, and the human disturbance factor is large are overcome. The natural disaster automatic early warning system comprises a satellite positioning early warning system, a sensor direct early warning system, a safety evaluation system used for receiving feedback signal data from the satellite positioning early warning system and the sensor direct early warning system and performing safety assessment, and an early warning device used for performing early warning according to an assessment result of the safety evaluation system, the satellite positioning early warning system comprises a displacement and positioning device and a satellite positioning device used for monitoring the displacement and positioning device in real time, and the sensor direct early warning system comprises a sensor set and an acquisition center used for receiving and collecting data acquired by the sensor set. According to the natural disaster automatic early warning system, the satellite positioning early warning system and the conventional sensor early warning system are combined, the rapidness of satellite monitoring is provided, and the monitoring accuracy of the conventional sensors is provided.

Description

technical field [0001] The invention relates to an early warning system, in particular to an automatic early warning system for natural disasters and a realization method. Background technique [0002] After more than 30 years of development, the scale and capacity of my country's highway and waterway transportation network have rapidly expanded, the structure has been continuously optimized, and the service level has been continuously improved. A relatively complete road and waterway transportation system has been established. At present, my country's expressways cover more than 90% of the country's medium-sized cities, ordinary trunk roads have basically realized the connection and coverage of administrative regions at the county level and above, and rural roads have reached almost all towns and villages. my country's total highway mileage, port handling capacity, inland river navigation mileage, highway passenger and freight volume, waterway freight volume and turnover vo...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, most of the slope monitoring for roads, waterways and railway networks requires special observers to monitor and alarm. This method has poor real-time performance and often cannot make timely and effective early warnings when encountering danger. Some automatic early warning technologies also hand over the decision-making power of early warning to specialized personnel.

In addition, there is a lack of electronic warning devices on disaster-prone road sections, and the failure to transmit disaster information to passing vehicles in time may easily cause secondary losses after disasters
