With the acceleration of urbanization and the improvement of transportation facilities, railway-cross public interchange culverts have become an important part of urban transportation. However, with the increase in the number of trucks and large vehicles, accidents in which bridges and culverts and height limit protective frames are damaged due to over-height vehicle collisions occur from time to time, which brings a serious threat to traffic safety. In order to effectively prevent the occurrence of such accidents, the collision warning system of railway-span public overpass culvert and height limit protection frame came into being, which has become a new weapon to ensure urban traffic safety.
The collision alarm system of railway cross-public overpass culvert and height limit protection frame is a set of intelligent system integrating real-time monitoring, data analysis, and early warning and alarm. The system installs ultra-high plane lidar, cameras and other sensor equipment to carry out all-weather and all-round monitoring of bridges and culverts and height limit protection frames. When the over-height vehicle approaches or hits the bridge culvert and the height limit protection frame, the system can respond quickly, and remind the driver and management personnel to take corresponding measures in time to avoid accidents through sound and light alarms, SMS notifications, etc.
As one of the core equipment, ultra-high plane lidar plays a vital role in the collision alarm system of railway-span public overpass culvert and height limit protection frame. Ultra-high plane lidar uses advanced laser ranging technology, which can measure the height of the vehicle with high precision and high speed, and compare it with the preset height limit value. Once the height of the vehicle exceeds the height limit, the lidar will immediately trigger an alarm mechanism to ensure a timely response.
Ultra-high plane LiDAR products offer a number of advantages. First of all, it has extremely high measurement accuracy and is able to accurately identify over-height vehicles and avoid false alarms and false negatives. Secondly, the response speed of LiDAR is fast, and it can complete measurement and alarm in a short time, effectively reducing the possibility of accidents. In addition, LiDAR also has the characteristics of strong anti-interference ability and high stability, and can work normally under harsh weather and environmental conditions.
In practical application, the collision alarm system of rail-span public overpass culvert and height limit protective frame has achieved remarkable results. Through the installation of ultra-high plane lidar and other sensor equipment, bridges and culverts and height limit protective frames in many cities have been effectively protected, and the incidence of ultra-high vehicle collision accidents has been greatly reduced. This not only ensures the smooth and safe flow of traffic, but also reduces the maintenance and management pressure of relevant departments.
