Description

Technical Field

[0001] This utility model relates to the field of traffic safety technology, specifically to a safety warning system for underground parking garage ramps. Background Technology

[0002] At the bends of ramps in two-way underground parking garages, vehicles traveling in opposite directions are highly susceptible to collisions. Currently, the main method used is to install convex mirrors to reduce the risk of collisions, but the effect is not significant and there are still considerable safety hazards.

[0003] Existing technology also provides a parking garage ramp blind spot warning device, mainly to improve driving safety at the intersection of the parking garage driveway and the ramp. This device uses infrared beam sensors to detect vehicles in the parking garage driveway and an indicator light at the top of the ramp to warn vehicles on the ramp. However, this method has the following drawbacks: ① It can only detect and warn vehicles in one direction, resulting in low safety; ② The infrared beam sensors are located at the intersection and cannot detect vehicles in advance. By the time the infrared sensors detect a vehicle, it is too late to warn, posing a significant risk; ③ The infrared beam sensors can detect vehicles in two lanes, including vehicles in the opposite lane, leading to false detections; ④ The indicator lights are located at the top of the ramp, making them difficult for drivers to observe and reducing their warning effectiveness. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, a safety warning system for underground parking garage ramps is provided. This system detects oncoming vehicles on the ramps in real time and alerts drivers, thereby improving the safety of ramp curves in underground parking garages.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] The underground parking garage ramp safety warning system is applied to the ramp curves in underground parking garages, including the uphill and downhill lanes; the uphill lane is divided into the front uphill section, the uphill curve section, and the rear uphill section along the direction of travel; the downhill lane is divided into the front downhill section, the downhill curve section, and the rear downhill section along the direction of travel.

For the bends of two-way underground parking garage ramps, sensors are installed on the ground ahead of the corresponding lane to detect whether a vehicle is approaching in real time; a warning device is installed ahead of the opposite lane, connected to the aforementioned sensors, to alert oncoming vehicles based on the detected vehicle traffic signals. Based on these measures, the presence of oncoming vehicles on the underground parking garage ramp is monitored in real time, and drivers are alerted, thereby improving the safety of the bends in the underground parking garage ramp.

[0020] 2. The warning devices are set in two forms: one is a ground warning light located on the ground, and the other is a voice alarm located next to the lane. Both of them use sound and light signals to remind drivers of oncoming vehicles whether there are vehicles passing by at the curve and curve of the underground garage, which greatly improves the safety of the curve and curve of the underground garage.
