Problems solved by technology

[0004] 1) Although the combination of modern ground and satellite communication means has been able to achieve coverage without blind spots, the cost of system construction and operation management is very expensive, and it is almost impossible to apply it in remote and scattered small areas threatened by heavy rainstorms and floods, forming an early warning network coverage blind spot;
[0005] 2) The entire system is complex, and communication systems, computer software and hardware systems, rainfall monitoring systems, and early warning systems must be built. The installation and use of these system equipment are complex, difficult to operate, maintain and manage, and require harsh operating conditions. Professional and technical personnel are required perform system administration;
The determination of the threshold value of the early warning p...

Embodiment Construction

[0027] The present invention will be further described below in conjunction with drawings and embodiments.

[0028] Technical principle of the present invention is as follows:

[0029] (1) Time relationship between rainfall and runoff

[0030] figure 1 Schematic diagram of the rainfall runoff segmentation and runoff process. from figure 1 It can be seen that since it takes a certain period of time for the rainfall to converge at the outlet of the watershed (or the disaster-causing site), there is a period of time difference between the maximum rainfall and the maximum runoff, or the occurrence of the disaster-causing rainfall intensity and the disaster-causing runoff, as shown in the figure value. This time difference provides a theoretical and practical basis for early warning of flood disasters by monitoring rainfall intensity. Therefore, it is only necessary to find and establish the mathematical relationship between rainfall intensity and disaster-causing runoff to o...

Abstract

The invention discloses an instantaneous unit hydrograph electronic model flood early warning machine, which comprises a tilting bucket rain gauge, wherein the tilting bucket rain gauge is connected with a net rain simulation module; the net rain simulation module is connected with an instantaneous unit hydrograph simulation module and a loss simulation module; and the instantaneous unit hydrograph simulation module is connected with a recession simulation module and a river basin output monitoring early warning module. The instantaneous unit hydrograph electronic model flood early warning machine has a simple and compact structure; an early warning judgment basis is an instantaneous unit hydrograph theoretical method; and compared with the conventional interval rainfall strength empirical method, the instantaneous unit hydrograph electronic model flood early warning machine has the advantages of high reliability, high early warning, degree-hour and accuracy, reliability in work, convenience for mounting, operation and maintenance, low energy consumption, long service life and wide application range.

Description

technical field [0001] The invention relates to a flood early warning machine, in particular to an instantaneous unit line electronic model flood early warning machine. Background technique [0002] The flood disaster caused by heavy rain is one of the most serious natural disasters in the world today. With the development of society and economy, the losses caused by this disaster are becoming more and more serious. According to the characteristics and laws of rainstorm and flood and social conditions, it is of great social and economic significance to research and develop reliable, practical, simple and economical rainstorm and flood early warning equipment for reducing disaster losses. [0003] At present, systems or equipment that automatically issue flood warnings through rainfall monitoring are mostly composed of communication and computer information management center systems, computer software and hardware systems, rainwater monitoring systems, early warning systems, ...
