Torrential flood house-entry early warning method and system, and alarm

Abstract

The present invention discloses a torrential flood house-entry early warning method and system, and an alarm. The method comprises the steps of: obtaining current rainfall information sent by a house-entry simple rainfall station through a preset relay station and current water level information sent by a house-entry simple water level station through a relay station; and if the current rainfall can reach a preset rainfall early warning threshold and / or the current water level reaches a preset water level early warning threshold, and performing alarm according to a pre-determined alarm mode. The method disclosed by the invention prolongs a transmission distance by the relay station to greatly enlarge the coverage range of the early warning system while effectively solving bad early warningtimeliness caused by a short transmission distance. The method introduces the alarm indoors, the rainfall information and the water level information are sent to the alarm in a user's house to achieve that early warning information directly enters the house for the user so as to obviously improve the early warning accuracy and the timeliness.

Description

technical field [0001] The invention relates to the field of monitoring and early warning, in particular to a method, an alarm and a system for early warning of mountain torrents entering households. Background technique [0002] Small watershed rainstorm and mountain torrent disaster forecasting and early warning technology is a very important work in the non-engineering prevention and control measures system. Due to the characteristics of mountainous small watershed floods, such as fierce onslaught, concentrated water volume, short forecast period, and shortage of data, the early warning, forecasting and prevention of them have always been It is a difficult point in disaster prevention and reduction work in mountainous areas. [0003] Mountain torrent disasters caused by local torrential rains in hilly areas, mountain torrents and other areas have the characteristics of rapid onset, loud noise, and damage to power supply facilities. In addition, there are remote scattered ...

AI Technical Summary

Problems solved by technology

[0003] Mountain torrent disasters caused by local torrential rains in hilly areas, mountain torrents and other areas have the characteristics of rapid onset, loud noise, and damage to power supply facilities. In addition, there are remote scattered households, "empty nest" families, widowed elderly, and some audiovisual disabilities in mountainous rural areas. Farmers account for a considerable number of cases, especially when mountain torrent disasters occur at night when people are sleeping soundly, so early warning broadcasts, simple rainfall alarms and other equipment that rely on sound transmission early warning outdoors have problems such as sound coverage blind spots and dead spots at critical moments. , leading to problems such as low timeliness of early warning, small coverage and low precision of early warning
