[0003] At present, as the floors of buildings such as communities and shopping malls are getting higher and higher, the use of elevators is becoming more and more extensive. People's pursuit of elevators is getting higher and higher. In some high-rise buildings, people's lives cannot be satisfied without elevators. However, as a common tool for high-level life, elevators still have many safety crises. Elevator accidents happen from time to time. In real life, we also see many incidents of people being trapped in elevator doors. People are the key to solving elevator safety problems. The current elevators have certain anti-pinch devices, but they are not perfect enough, and there are still some accidental situations.
