Embodiment 1

[0032] Such as Figure 1~4As shown, a kind of early warning and control equipment to deal with the source of short-term heavy rainfall in the community, including the community meteorological central station 1, the roof rainwater intelligent regulation and storage device 2, the government's emergency management information center 4 and solar panels 24, the community meteorological central station 1 Monitor the rainfall intensity in real time through the tipping bucket rain gauge. The tipping bucket rain gauge of this embodiment is a double tipping bucket rain gauge with a model of JXBS-3001-YL, and its measurement resolution is 0.2mm. The information center 4 is signal connected; the roof rainwater intelligent regulation and storage device 2 includes a main control circuit module 21 and a roof drain control module 22, and the roof drain control module 22 includes a cofferdam type baffle 221 and a driving mechanism 222, so The cofferdam type baffle plate 221 surrounds the verti...

Abstract

The invention particularly relates to an early warning and control method for a short-time heavy rainfall community source. The method comprises the steps that S1 a community weather master station monitors the rainfall intensity in real time through a tipping bucket rain gauge, the sampling time is recorded as delta T, the collected total rainfall amount is recorded as V, and the rainfall intensity is recorded as P, and then according to a source heavy rainfall recognition and early warning algorithm, P = V / delta T; S2 the community weather master station compares the rainfall intensity P with a set early warning threshold value K, if P is greater than K, it is judged that heavy rainfall occurs once in a short time, otherwise, it is judged that no heavy rainfall exists in the short time; and S3 a roof rainwater intelligent regulation and storage device regulates and controls the water storage capacity of the roof by controlling the rainwater discharge amount of a roof water outlet, and when the roof rainwater intelligent regulation and storage device receives a heavy rainfall signal, the roof water outlet is closed by the roof rainwater intelligent regulation and storage device; and when the roof rainwater intelligent regulation and storage device receives a short-time heavy rainfall-free signal, the roof rainwater intelligent regulation and storage device opens the roof water outlet.

Description

technical field [0001] The invention belongs to the technical field of urban waterlogging prevention and sponge city construction, and in particular relates to an early warning and control method and equipment for responding to short-term heavy rainfall community sources. Background technique [0002] At present, in the process of sponge city construction, low-impact development technical measures and deep storage tunnels are mainly used to control urban waterlogging. According to existing research literature and engineering application results, conventional low-impact development technical measures cannot solve the problem caused by short-term heavy rainfall. urban waterlogging problem. Due to global warming, hardening of urban underlying surfaces, and urban heat island effect, the frequency of extreme short-term heavy rainfall has increased. For example, a short-term heavy rainfall event occurred in Shenzhen on April 11, 2019. The ten-minute rainfall reached 39.2mm, short...
