I: Requirements background and pain points<\/b><\/strong><\/p>\n

        High-speed railway station is an intensive place with a very large flow of people. In order to prevent passengers from illegally invading the end of the platform to cross the railroad line, the Railway Bureau requires the installation of an anti-passage system, which can detect and capture the illegal invasion in time and stop the violation to avoid major losses.<\/p>\n

        In order to pursue the high accuracy and stability of the system, the \"millimeter wave radar + camera + voice alarm\" program is usually used. It can accurately recognize whether there is someone intruding within a set short distance, and if there is someone intruding, it will link up with the alarm to broadcast voice and the camera to capture the picture.<\/p>\n

        Although the system can accurately identify whether there are people who mistakenly enter the dangerous area, but can not distinguish the attributes of the people crossing the system, the legitimate railroad station maintenance staff to carry out normal safety checks will also trigger the alarm, which greatly affects the passenger experience, and at the same time a waste of human resources station management.<\/p>\n

According to the status of the relays, it can be determined whether there are staff members (usually wearing white list tags) in the alarm area, so as to decide whether to release the anti-passage alarm.
