Technical Field

The invention relates to a safety alarm system, in particular to a safety alarm system for a no-standing area in a vehicle.

Background

The interior of a bus, a bus or a rail transit vehicle is provided with a yellow area for prohibiting passengers from standing, and the yellow area is used for warning the passengers not to stand or stay in the dangerous area. But most passengers stand or lean on the "yellow zone" due to congestion or fatigue. This may cause accidents such as door opening and closing obstruction, driver sight obstruction, untimely handling of dangerous situations, and throwing of passengers who are opening the door by mistake.

At present, the main solution to the problem is to set a warning sign in a no-standing area, and investigation finds that the reminding strength is not enough and is easy to ignore; some patents mention that an infrared receiving and transmitting device is used for monitoring, but infrared rays are greatly influenced by the environment and are easy to generate misjudgment; there are also patents that mention the "door in door" in this area, which undoubtedly increase the overall vehicle cost and weight.
