Embodiment 1

[0061] This embodiment provides a system for quickly finding the height of water accumulation and recording the first water accumulation point, such as figure 1 As shown, it includes: a central processing unit and M waterlogging detection terminal devices, where M is an integer greater than 1.

[0062] Each of the accumulated water detection terminal devices has a specific ID number, and is arranged in the detected area according to a certain distance. and data output unit;

[0063] The water height judging sensor includes several judging contacts A i Arranged on the insulation board in sequence along the direction away from the road surface, where 0≤i≤n, each of the judgment contacts A i The resistance value ≈0 and there is a certain interval between two adjacent judgment contacts; each judgment contact A i One end of the resistor R is connected to the positive pole of the power supply V + Connected; the other end is led to the node J to be judged by the wire i ;

[006...

Embodiment 2

[0078] This embodiment also provides a method for quickly discovering the height of the accumulated water and recording the system that first forms the accumulated water point based on the above system, including the following steps:

[0079] S1: Set M waterlogging detection terminal devices with a specific ID number on the detected area according to a certain distance, M is an integer greater than 1; each of the waterlogging detection terminal devices detects the road surface of the road section where it is located Whether there is water accumulation, and the detection result and the current time and the ID number of the water accumulation detection terminal equipment are sent to the central processing unit, and the central processing unit includes a clock synchronization control module, a data processing module, a terminal equipment information database and a display module; The clocks of the M waterlogging detection terminal devices and the central processing unit are kept c...

Embodiment 3

[0095] In this embodiment, the interval between the judging contacts can be selected according to the requirements of judgment accuracy. In theory, the smaller the interval is, the higher the judgment accuracy is, but the engineering quantity of the system's wiring is also larger. Therefore, in order to balance the accuracy and The relationship between the engineering quantities of the laid lines, the present embodiment selects the judgment contact A i with judgment contact A i+1 The distance between them is 3-10 cm, such as 3 cm, 5 cm, 7 cm or 10 cm, but a preferred embodiment is 5 cm.

[0096] The highest position of the inspection contact is determined according to the maximum height of the judged ponding. Generally, when the height of the ponding is above 0.5 meters, traffic control must be implemented. Considering the requirement of redundancy, this embodiment The following improvements are made on the basis of the first embodiment. In this embodiment, 25-40 judgment con...

Abstract

The invention relates to a system and method for rapidly finding a ponding height and recording a first formed ponding point. The system for rapidly finding the ponding height and recording the first formed ponding point is composed of M ponding monitoring terminal devices which are arranged in a central processing unit and are distributed on the road surface at intervals. The method for rapidly finding the ponding height and recording the first formed ponding point comprises the steps that 1-M numbering is carried out on the ponding monitoring terminal devices, corresponding positions are stored on a terminal information database of the central processing unit in an ID serial number mode, the central processing unit reads surface ponding results of the ponding monitoring terminal devices at the same time, and thus the first formed ponding point is displayed on the central processing unit. The system for rapidly finding the ponding height and recording the first formed ponding point further has the function of fault judgment, can effectively judge ponding on the road surface and the ponding height, can also judge whether the system has faults or not when ponding does not exist on the road surface, can instantly give out alarm information to remind command personnel of a public traffic management department to carry out timely maintenance once the system has the faults, and effectively solves the problem that an alarm cannot be given out in time when ponding occurs on the road surface due to the fact that the system faults cannot be found in one second.

Description

technical field [0001] The invention relates to the field of road traffic condition monitoring, in particular to a system and method for quickly discovering the height of accumulated water and recording the first formed water accumulation point. Background technique [0002] With the rapid development of social economy, urban road traffic is becoming more and more busy, and traffic congestion is becoming more and more serious, especially when there is a sudden rainstorm, the drainage speed of the road surface lags behind the rainfall speed and water will accumulate, and the accumulated water will hinder traffic when it reaches a certain height Safety. For example, the torrential rains in Beijing on July 10, 2010, June 23, 2011, and July 21, 2012 all caused large-scale traffic congestion in the urban area of ​​Beijing. Due to the lack of waterlogging equipment in the waterlogged section, vehicles The damage and casualties have brought serious losses to the country and people...
