Description

Automatic sensing early warning signs for waterlogged road sections

technical field

The invention relates to an automatic induction early warning sign on a waterlogged road section.

Background technique

Recently, continuous torrential rains in Beijing, Tianjin, and Hebei have caused a large amount of water accumulation on low-level road sections. Since there is no clear "waterlogged road" warning message, many vehicles cannot know the wading road ahead and fail to detour in advance. Or hastily underestimated the water depth of the road section and directly drove into the deep water area, causing unnecessary vehicle damage and even casualties. Cities will be put to the test with the onset of the rainy season and may experience similar situations. In order to avoid the above accidents, it is imperative to establish a fast, effective and timely emergency warning system.

Contents of the invention

Purpose: In order to overcome the deficiencies in the prior art, the present invention provides an automatic induction early warning sign for waterlogged sections, which has a simple structure and is easy to use. In the early warning state, the water level detector at the front section detects the water level of the road section, and the central controller collects and analyzes the detection value of the water level detector at the front section, and displays three levels of early warning information on the LED traffic signs at the rear end according to different water level values.

Technical solution: In order to solve the above technical problems, the technical solution adopted in the present invention is: an automatic induction early warning sign for waterlogged road sections, which is characterized in that: the automatic induction early warning sign for waterlogged road sections includes a water level detector, an LED traffic sign and a central Controller; the central controller is connected with the water level detector and the LED traffic sign, realizes the core control function of the automatic induction warning sign of the water accumulation road section, and converts the monitoring data of the water level detector into different warning display states of the LED traffic sign.

The automatic induction early warning sign on the waterlogged road section is powered by a solar battery arranged on the LED traffic sign.

The water level detector is arranged on the side edge of the road, includes four sensing probe points for sensing the height of the water level, and uses a DC 12V weak current as the system power supply.

As a preferred solution, the water level detector is provided with a cylindrical protective cover for protecting the sensing probe points, and the protective cover is uniformly provided with openings. the

As a preferred solution, the LED traffic sign includes a main sign for warning and an auxiliary sign for displaying the height of the road surface water level. the

As a preferred solution, the LED traffic sign is installed in the form of a single column, and a strobe light with strong warning performance is placed on the top.

Beneficial effects: the automatic induction early warning sign on the waterlogged road section provided by the present invention can warn the passing people in advance to pay attention to the water level ahead and drive cautiously, so as to realize the timeliness and effectiveness of traffic management and control, avoid disasters and accidents, and ensure the traffic safety of the waterlogged road section Unimpeded; powered by solar batteries, no external power supply is required, avoiding the external limitations that cannot be connected to electricity in remote areas.

Description of drawings

Fig. 2 is a schematic structural diagram of the water level detector in the present invention.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1, it is a kind of automatic induction early warning sign of road section with water accumulation, described automatic induction early warning sign of road section of accumulation of water comprises water level detector, LED traffic sign and central controller; Central controller is connected with water level detector and LED traffic sign The connection realizes the core control function of the automatic induction warning sign on the waterlogged section, and converts the monitoring data of the water level detector into different warning display states of the LED traffic signs; the automatic induction warning sign on the waterlogged section passes through the solar battery installed on the LED traffic sign powered by.

As shown in Figure 2, the water level detector is installed on the side edge of the road. The system uses DC 12V (no harm to humans) weak current as the system power supply. It is composed of four sensing points, of which A, B, and C are The information collection probe point, the common zero point is the common zero terminal of the A, B, and C probe points:

When the water level is below point A, detection points A, B, C and the common zero point cannot form a circuit, and the system recognizes that the water level H0 is below point A, which is in blue state;

When the water level reaches point A, the detection point A and the common zero point form a loop, and the detection point A is turned on, and the system recognizes that the water level H1 is between A and B, and it is in a yellow state;

When the water level reaches point B, detection points A and B form a loop with the common zero point, and the detection points A and B are turned on. The system recognizes that the water level H2 is between B and C, and it is in an orange state;

When the water level reaches point C, detection points A, B, and C form a loop with the common zero point, and the detection points A, B, and C are turned on. The system recognizes that the water level H3 is between the C points, and it is in a red state;

A cylindrical protective cover for protecting the sensing probe point is arranged outside the water level detector, and openings are uniformly arranged on the protective cover. Prevent damage or misjudgment of data from direct impact of some floating objects or dirt on the probe when water flow occurs.

LED traffic signs are usually installed in the first 30 meters of the road section at ground level to meet the buffer distance for advance notice; the signs are installed on a single column of ?? Rectangular sign, the layout is engineering-grade reflective film, the main sign pattern is "Water-crossing road" triangle warning sign (alarm 32), the lower part is "water depth is dangerous, pass carefully", and high-power LED light-emitting tubes are embedded in the pattern; auxiliary signs There are three LED red, orange, and yellow warning signs respectively. The content of the red sign is "water depth 30cm", the content of orange sign is "water depth 20cm", and the content of yellow sign is "water depth 10cm".

It is displayed as follows:

a) When blue is in normal state, the main logo is displayed, and the auxiliary logo is not displayed;

b) In the yellow warning state, the main sign displays, and the auxiliary sign 1 displays "water depth 10cm";

c) When the blue color is normal, the main sign will display, and the auxiliary sign 2 will display "water depth 20cm";

d) When blue is in normal state, the main sign will display, and the auxiliary sign 3 will display "water depth 30cm". the

Central controller: it is the core control part of the present invention, connecting between the front-end water level detector and the rear-end LED traffic sign. By invoking the water level detection data in the front stage, after logical processing and analysis, the three warning display states of the LED traffic signs in the back end are assigned matching values.

The logical structure is as follows:

a) If A=0 & B=0 & C=0, the water level status is blue and normal;

b) If A=1 & B=0 & C=0, the water level status is yellow warning;

c) If A=1 & B=1 & C=0, the water level status is orange warning;

d) If A=1 & B=1 & C=1, the water level status is red warning.

The power supply system is powered by a solar battery, and the solar energy charges the battery to ensure sufficient power. The single-chip computer judges the battery voltage to protect the battery from overcharge and overdischarge.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also possible. It should be regarded as the protection scope of the present invention.
