Description

Technical Field

[0001] The present invention relates to the technical field of road facilities, and in particular to a luminous curbstone system based on photovoltaic power supply and a lighting control method. Background Art

[0002] Curbstones refer to vertical or inclined stone or concrete structures on both sides of the road, which prevent vehicles from deviating from the road and reduce the risk of traffic accidents. Compared with other safety facilities such as road guardrails, curbstones are low-cost and easy to install and maintain. They can not only flexibly adapt to roads with different curves, but also their low profile can reduce the obstruction of the driver's vision. Therefore, they are widely used in road engineering. However, at night or in bad weather such as rain, fog and snow, due to low visibility, curbstones still cannot play a role in warning and protecting vehicles. In order to improve traffic safety, it is necessary to add reflective signs on curbstones.

[0003] Reflective signs commonly used on curbs in the prior art include reflective ground nails, reflective stickers, reflective paints, etc. These materials are easily affected by vehicle collisions or environmental factors during use, and may be worn, fall off, or have reduced reflective effects. They must be regularly maintained and replaced, have high long-term use costs, and have unstable warning effects. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in view of the shortcomings of the existing technology, a luminous curb system and a lighting control method based on photovoltaic power supply are provided, which have low maintenance costs, stable traffic guidance effects, and can effectively improve road traffic safety.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] 1. A photovoltaic powered luminous curb system

[0009] Furthermore, the humidity sensor 9, the illumination sensor 10, the battery 5 and the controller 6 are all arranged in the roadside idle area 3, and the roadside idle area 3 specifically includes: a roadside green belt or a roadside open space.

[0010] Furthermore, the photovoltaic assembly 4 is arranged in an area where the roadside lighting condition meets the requirements, and the area where the lighting condition meets the requirements specifically includes: a road slope or a roof of a roadside building.

[0011] Furthermore, the light strips 8 are embedded in grooves of the curbstones 2 on both sides of the road, and the grooves are opened along the extending direction of the road.

[0012] Furthermore, the opening direction of the groove is inclined downward, and the opening direction forms an inclination angle α with the horizontal plane, 0°<α<30°.

[0013] Furthermore, the light strip 8 is a DC-powered LED light strip, and the photovoltaic assembly 4 is installed in a grid-connected manner and connected to the public power grid through an inverter.

[0014] Furthermore, the capacity and power of the photovoltaic module 4 and the battery 5 are calculated and determined based on the illumination requirements of different working conditions in the road area and the annual average light intensity.

[0015] Furthermore, the humidity sensor 9 and the illumination sensor 10 are connected to the controller 6 via a signal cable, and the controller 6 is connected to the light strip 8 via a control cable;

[0016] The storage battery 5 is connected to the light strip 8 , the controller 6 , the humidity sensor 9 and the illumination sensor 10 respectively through power supply cables.

[0017] 2. A Lighting Control Method for Luminous Curb System Based on Photovoltaic Power Supply

[0018] Based on the same inventive concept, the present invention also provides a lighting control method of the luminous curb system as described above, which specifically comprises the following steps:

[0019] S1, set the humidity threshold H0 and the illumination threshold I0 through the controller, and turn on the humidity sensor and the illumination sensor;

[0020] S2, the humidity sensor and the illumination sensor transmit the collected road environment humidity information and illumination information to the controller respectively, and the controller compares the environmental humidity value and illumination value with the preset humidity threshold H0 and illumination threshold I0 respectively;

[0021] S3, if the detected ambient humidity value H is greater than the humidity threshold H0, it is judged to be rainy, foggy or snowy weather, and the light strip fog light mode is turned on; if the detected ambient humidity value H is less than the humidity threshold H0, and the ambient illumination value I is less than the illumination threshold I0, it is judged to be dark, and the light strip night light mode is turned on; otherwise, the light strip is turned off.
