A method for dynamically identifying the axle load of a vehicle under vertical displacement-influenced surface loading, comprising: extracting beam type and structural parameter control information; extracting theoretical displacement-influenced surface control information at vertical displacement measurement points; correcting the displacement according to the results of the bridge displacement-influenced surface in the loading test Affected surface; set trigger recognition vehicle axle load identification corresponding vertical displacement threshold; vehicle axle load identification system identifies vehicle axle load passing through the bridge; vertical displacement triggers bridge safety risk early warning system. The present invention integrates comprehensive applications such as big data, machine learning, deep learning, safety monitoring, automatic control, computer technology, precision sensing technology, etc., and realizes based on the extraction of structural characteristic parameters and real-time structural response, based on structural dynamic loads. The vertical displacement is the identification parameter, and the reverse identification of the bridge vehicle load is realized to realize the identification system and method of a new generation of intelligent monitoring products with intelligent computing as the core and self-induction, self-adaptation, self-learning and self-decision as the notable features.

The invention provides a combined regenerative energy power supply device which comprises a wind power generation unit, a photovoltaic power generation unit, a high-capacity energy storage element and a coordination control unit, wherein the high-capacity energy storage element is used for storing electric energy; the coordination control unit is used for enabling the wind power generation unit or the photovoltaic power generation unit to charge the high-capacity energy storage element when the electric quantity produced by the wind power generation unit and the photovoltaic power generation unit is higher than the demand of users in a region, and supplying power to an outside power pool system under the condition that the electric energy is surplus after the charging of the high-capacity energy storage element is finished; and the coordination control unit is also used for cutting off the wind power generation unit and the photovoltaic power generation unit and enabling the outside power pool system to charge the high-capacity energy storage element and supply power to loads of the users in the region when the electric quantity produced by the wind power generation unit and the photovoltaic power generation unit is lower than the demand of the users in the region. According to the invention, line loss and construction investment caused by remote locations of power generation places and long distances from loads can be effectively reduced.

The invention discloses a regional landslide hazard rainfall early warning method and system. For overcoming the defects that in the prior art, according to a landslide hazard rainfall early warning threshold value determined by drawing a lower envelop line in a scatter diagram, the position of the lower envelop is random, and the threshold value is likely to be small, the regional landslide hazard rainfall early warning method comprises the steps that the region is within the landslide hazard early warning range, rainfall capacity data is monitored inside a disaster frequent-occurrence period, and when the rainfall capacity meets the early warning condition, corresponding landslide hazard early warning signals are given out. The rainfall capacity early warning conditions are composed of the judgment rainfall Rc and various levels of early warning threshold values, wherein Rc is a monitoring object in rainfall early warning, and Rc and the various levels of early warning threshold values are determined and obtained through a statistical analysis method on the basis of historic rainfall and landslide hazard data within the regional range. The invention further provides an early warning system utilizing the method. The method is reliable in principle, key rainfall capacity early warning conditions in the method can be obtained on the basis of regional hazard data, and the regional adaptability is high.
