specific Embodiment approach 1

[0037] Specific implementation mode one: In this implementation mode, a concrete detection and early warning system for icing on the bridge road surface includes:

[0038] Road surface temperature collection module, atmospheric temperature and humidity collection module, analysis module and early warning module;

[0039] The road surface temperature acquisition module is used to obtain the current road surface temperature;

[0040] The atmospheric temperature and humidity acquisition module is used to obtain the current atmospheric temperature and humidity;

[0041] The analysis module is used to analyze the data transmitted by the atmospheric temperature and humidity acquisition module and the road surface temperature acquisition module and issue instructions to the early warning module, that is, whether to issue road icing early warning information;

[0042] The analysis module is arranged inside the spike;

[0043] The core component of the analysis module is a single-chi...

specific Embodiment approach 2

[0048] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the core component of the road surface temperature acquisition module is the road temperature sensing component 10;

[0049] The road temperature sensing part 10 is composed of a temperature sensing probe 101, a connection end 102 and a data transmission line 103; see figure 2 Road temperature acquisition module structure diagram.

[0050] The road temperature sensing part 10 adopts a DS18B20 temperature sensor;

[0051] After fully considering the rationality of the detection effect of each component, the road temperature sensing part 10 is arranged on the lower surface of the road stud, and the road temperature sensing part 10 is arranged in the groove of the road surface, see image 3 ;

[0052] The depth of grooves on the road surface is 2 cm, and the width is 1 cm. The current road surface temperature is obtained by direct detection.

[0053] Considering that the tem...

specific Embodiment approach 3

[0058] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that: the core component of the atmospheric temperature and humidity acquisition module is the atmospheric temperature and humidity detection component 20;

[0059] The atmospheric temperature and humidity detection part 20 includes an NTC temperature measuring element 201 and a resistive humidity sensing element 202, and is connected with a high-performance 8-bit single-chip microcomputer;

[0060] The atmospheric temperature and humidity detection part 20 has four pins, 1pin (VDD) power supply 3-3.5VDC; 2pin (DATA) serial data, which is a single bus; 3pin (NC) is empty and needs to be suspended; 4pin (GND) Ground, connected to the negative pole of the power supply; see Figure 4 Atmospheric temperature and humidity acquisition module structure diagram.

[0061] In order to meet the requirement that the atmospheric temperature and humidity detection part 20 must be ...

Abstract

The invention discloses a bridge pavement icing detection and early warning system and method, and relates to a bridge pavement icing detection and early warning system and method. The invention aimsto solve the problems that dark ice cannot be accurately detected and icing early warning cannot be performed in real time due to the fact that existing detection equipment detects icing by means of icing external characteristics. The method comprises the steps that 1, an atmospheric temperature and humidity acquisition module acquires air temperature data and air humidity data, and a pavement temperature acquisition module acquires pavement temperature data; 2, the data obtained in the step 1 is processed to obtain a dew point temperature; 3, the analysis module performs second preset condition judgment on the current dew point temperature, and if a second preset condition is met, the analysis module issues an early warning command; if the second preset condition is not met, the analysismodule does not issue the early warning command; and 4, the early warning module performs early warning on the pavement after receiving the early warning command issued by the analysis module. The invention is applied to the field of traffic safety.

Description

technical field [0001] The invention relates to a bridge pavement icing detection and early warning system and method in the field of traffic safety, which is widely applicable to bridge pavements where icing occurs frequently in winter. Background technique [0002] Icing on the road surface is a common phenomenon that endangers road driving safety. Ice on the road leads to a significant decrease in the friction coefficient of the road surface, and vehicle skids, sideslips or wheel idling occur, which can easily induce serious traffic accidents and cause huge losses to the country and people's property. According to statistics, the incidence of traffic accidents caused by icy roads is 10 times that of dry roads. How to reduce the vehicle accident rate on icy roads has become a major problem for road transportation. Among various types of road sections, the bridge section itself has the characteristics of being closed on both sides, which has caused certain difficulties for...
