"Warning area, leave as soon as possible!" After the audible and visual alarm, the AI portrait recognition intelligent warning system of Huaguan Expressway issued a voice prompt to advise pedestrians and non motor vehicles about to enter the expressway to leave quickly. On the 11th, the reporter learned that in order to further improve the safety level of the expressway and effectively prevent pedestrians and motorcycles from accidentally running into the expressway and causing road traffic accidents, Guangzhou Communications Investment Huaguan Expressway, adhering to the concept of "civil air defense+technical defense", deployed AI human image recognition intelligent warning system at Liangtian East Station to effectively and intelligently deal with the pain point of pedestrians and non motor vehicles illegally driving on the expressway. At Liangtian East Station, the reporter saw that the AI portrait recognition intelligent warning system can effectively identify people, vehicles, roads and other objects within 50 meters of the square and ramp in front of the entrance with only one camera gun. "The AI portrait recognition intelligent warning system consists of three parts: intelligent camera, signal detection transmitter and audible and visual alarm. Through the background system setting, the camera gun can trigger the signal to start the audible and visual alarm in the toll canopy when the camera gun detects that there are pedestrians or non motor vehicles passing, so as to realize the immediate alarm function." He Qiyi, the head of Guangzhou Jiaotou Rapid Transit Liangtian Central Station, told reporters. The reporter learned that in the traditional video monitoring process, if the weather is poor or the vision is blocked, the monitoring role of the camera gun will be greatly reduced. The AI portrait recognition intelligent alert system can break this dilemma. "Whether at night or in bad weather, the toll station site can be accurately controlled 24 hours without being affected by the environment." He Qiyi introduced that the system seems to have built an invisible "wall" on the toll plaza. Once pedestrians or non motor vehicles enter, the system will remind them with an audible and visual alarm and warning voice to warn pedestrians that they have entered the warning area, and remind staff to pay attention to the emergency situation in the toll plaza, Make sure to go to the target person in time. He Qiyi said that it has always been a difficult problem for highway management to efficiently detect pedestrians' behaviors of running into highways by mistake, to quickly respond and to quickly persuade them to return. The reporter learned that since the device was put into Liangtian East Railway Station, the road section has successfully intercepted pedestrians and non motor vehicles running on the expressway by mistake for many times through the pedestrian warning system, improving the expressway safety index.
