Urban storm flood monitoring and traffic controlling and guiding system and method

Abstract

The invention discloses an urban storm flood monitoring and traffic controlling and guiding system and method. The urban storm flood monitoring and traffic controlling and guiding system comprises a water depth data collecting and rectifying unit, a unit for analyzing and predicting water depth and on-off control of a drainage pump station and an early warning issuing and traffic controlling and guiding processing unit. The water depth data collecting and rectifying unit is used for performing comparison and check analysis by collecting water depth data of different types at water accumulating spots and obtaining water depths at the water accumulating spots. The unit for analyzing and predicting water depth and on-off control of the drainage pump station is used for performing trend analysis and rolling correction on the water depths of the water accumulating spots by combining zone rainfall data of surrounding rainfall stations on the basis of the water depths obtained by the water depth data collecting and rectifying unit and achieving automatic on-off of a drainage pump unit according to an accumulating water depth predicting curve. The early warning issuing and traffic controlling and guiding unit is used for processing obtained traffic controlling and guiding information and sending the information to a controller and early warning and instructing pedestrians and vehicle drivers in various manners according to safety pass standards of water-accumulating roads. The urban storm flood monitoring and traffic controlling and guiding system and method have the advantages of being reliable in data, stable in communication, comprehensive in function, professional in handling and the like.

Description

technical field [0001] The invention relates to the fields of water level monitoring and traffic control, in particular to a system and method for urban rainstorm flood monitoring and traffic control and guidance. Background technique [0002] The development of road traffic has brought convenience to people's travel, but the increase of the impermeable layer has led to the concentrated and rapid confluence of rainfall, which has brought great challenges to the drainage system. In recent years, the problem of urban waterlogging has been very serious, and the flooding of sunken overpasses is particularly serious, which has caused huge losses to people's lives and properties. Analyzing the personnel and property loss incidents, it can be found that the lack of early warning information is an important factor. If everyone can get the water depth information of the waterlogged road section when passing, vehicles that have not entered can avoid the waterlogged route. Vehicles th...

Problems solved by technology

[0003] The existing wading traffic guidance system can realize single-point water level monitoring, rainfall monitoring and image monitoring, and can also realize on-site traffic control and indication system transformation at a single point, but there are the following problems: (1) The monitoring method is single and the data Failed to correct effectively; (2) The installation method is complicated, such as the float type water level gauge and the pressure type water level gauge need to dig side wells, which not only requires a large amount of engineering, but also takes up too much space, which is not suitable for installation in urban environments; (3) Data Ineffective use, due to data accuracy and other issues, the data is only used as historical data for analysis, and cannot provide real-time services for traffic control; (4) Lack of effective data analysis and forecasting means

Single data and isolated information islands lead to unreliable data, which cannot be easily released. At the same time, unreliable data also prevents subsequent monitoring from obtaining data that can be checked. The final result is that the monitoring data cannot be used effectively. Due to lack of data and unsmooth information, the on-site control and guidance work failed to realize warning, circuit breaker and turn-off valve in time
