Description

Technical Field

[0001] This utility model relates to the field of environmental condition detection technology, specifically to a highway fog visibility monitoring device. Background Technology

[0002] Dense fog is a type of dense fog that appears within a localized area of ​​tens to hundreds of meters in a dense fog environment, influenced by local microclimates. Visibility is good outside the fog patch, but within the fog patch, visibility is less than 50 meters. Studies show that the large temperature difference between day and night on highway surfaces makes dense fog more likely to form. The sharp decrease in visibility under dense fog conditions severely affects drivers' perception, interferes with their vision, and causes illusions of distance and speed, easily leading to traffic accidents, road congestion, and disruption to highway operations. Current installation procedures for highway dense fog monitoring devices typically involve installing frames along both sides of the highway, laying power and signal cables along the frame, and finally installing visibility meters on each frame and connecting them. This process is not only complex but also makes it impossible to move the monitoring points. Utility Model Content

The frame 1 includes a base 11, a pole 12 mounted on the base, and a U-shaped top beam 13 fixed to the top of the pole. The data acquisition mechanism 2 includes a detachable component mounted in the top beam 13. The visibility meter 21 is mounted on a pair of LED infrared light emitters 22 at both ends of the top beam 13. The LED infrared light emitters 22 are installed and fixed at a 30° angle downward from the horizontal plane. The probe of the visibility meter 21 is located in the optical path of the LED infrared light emitters 22. The main control box 3 is fixed to the base 11. The box is equipped with a display screen 31 and a main control board 32 is installed inside the box. The power supply mechanism 4 includes two photovoltaic panels 41 obliquely mounted on the upright 12 and an energy storage battery 42 installed in the main control box 3.

[0022] Implementation method 2: such as Figure 3As shown, the main control board 32 of this highway fog visibility monitoring device integrates a processor, an RS485 interface module, a display driver module, a voltage regulator charging module, a power conversion module, a storage module, and a wireless data transmission module. The signal output terminal of the visibility meter 21 is connected to the processor input terminal via the RS485 interface module, and the processor output terminal is connected to the display screen 31 via the display module.

The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0023] During operation: The main control board controls the LED infrared light emitter to emit infrared light. After passing through fog, the light is received by the visibility meter probe, which converts the received light loss into visibility parameters and sends them to the main control board. The data is then output to the display screen and simultaneously transmitted to the remote monitoring terminal via the wireless data transmission module. The LED infrared light emitters, positioned at a 30° angle, provide sufficient scattering fan area while ensuring that the emitted light does not interfere with each other, thereby ensuring that the probe receives appropriate light and that the data output by the visibility meter is accurate. The photovoltaic panel collects solar energy and converts it into current, which is then processed by the voltage regulation and charging module to charge the energy storage battery. The energy storage battery discharges and is converted by the power conversion module to DC3.3-5V to power the main control board components, DC12V to power the visibility meter and LED infrared light emitter, and DC9V to power the display screen and display driver module circuit.

[0024] This highway fog visibility monitoring device is highly integrated, fully functional, energy-efficient, and easy to deploy in areas prone to fog along highways and move between different areas. It can collect and store visibility data at its location in real time, and transmit it wirelessly and provide on-site alerts for centralized monitoring and analysis by the back-end system, as well as for drivers' on-site reference.
