Embodiment 1

[0030] 1) Install a non-contact ultrasonic water level gauge in culverts, pools, reservoirs and lakes that require early warning. The water level gauge transmits the water level information to the server in real time through the IoT serial port module at least once every five seconds. In order to improve the accuracy of the water level The maximum statistical unit of a single indicator cannot exceed centimeters, and the distance between the initialized water bottom and the overflow level is set as the dangerous reference water level value;

[0031] 2) Through the installed and deployed small weather stations in the same area or the self-built small big atmosphere, the rainfall information will be included in the weather station information in the same township. The rainfall information needs to be submitted to the real-time at the maximum interval of every five seconds. For rainfall information, the rainfall level obtained is R1, and the maximum single-index statistical unit is...

In order to improve the accuracy of the water level The maximum statistical unit of a single indicator cannot exceed centimeters, and the distance between the initialized water bottom and the overflow level is set as the dangerous reference water level value;

[0037] 2) Through the installed and deployed small weather stations in the same area or the self-built small big atmosphere, the rainfall information will be included in the weather station information in the same township. The rainfall information needs to be submitted to the real-time at the maximum interval of every five seconds. For rainfall information, the rainfall level obtained is R3, and the maximum single-index statistical unit is...

[0042] 1) Install a non-contact ultrasonic water level gauge in culverts, pools, reservoirs and lakes that require early warning. The water level gauge transmits the water level information to the server in real time through the IoT serial port module at least once every five seconds. In order to improve the accuracy of the water level The maximum statistical unit of a single indicator cannot exceed centimeters, and the distance between the initialized water bottom and the overflow level is set as the dangerous reference water level value;

[0043] 2) Through the installed and deployed small weather stations in the same area or the self-built small big atmosphere, the rainfall information will be included in the weather station information in the same township. The rainfall information needs to be submitted to the real-time at the maximum interval of every five seconds. For rainfall information, the rainfall level obtained is R6, and the maximum single-index statistical unit is...

Abstract

The invention relates to the technical field of early warning equipment, and discloses a method for reckoning flood and overflow occurrence time according to meteorological data, which comprises the following steps of 1) installing non-contact ultrasonic water level gauges in culverts, pools, reservoirs, lakes and the like which need early warning in advance. According to the method for reckoningflood and overflow occurrence time according to meteorological data, associated determination is carried out through rainfall of different levels and water level changes, an initialized calculation model can be automatically established by accumulating real data to acquire and classify original data generated by rainfall of six levels in real time, therefore, the volume of an area needing to be calculated does not need to be measured manually, and the calculation accuracy is improved by refining the minimum calculation unit time and the rainfall water level. Meanwhile, the more the accumulated data is, the longer the use time is, the higher the calculated data and the foreseeable accuracy are, manual calibration is not needed; and the equipment is low in overall cost and low in human input and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of early warning equipment, in particular to a method for estimating the occurrence time of floods and overflows based on meteorological data. Background technique [0002] Urban flood disasters have a huge impact on the city, bringing immeasurable losses to the city. The city is flooded with water, traffic is paralyzed, housing and property are threatened, water resources are polluted, diseases spread rapidly, and building facilities are destroyed. Casualties, mountain torrents in distant urban areas, poor drainage, in addition to urban waterlogging, will also cause surrounding farmland and villages to be flooded, crop production will be severely reduced, livestock and people's lives and properties will be threatened, causing serious economic losses. [0003] At present, the construction of urban flood disaster early warning system is relatively lagging behind, and the monitoring methods used in the existin...
