Generally, various temporary operating platforms and operating frames are often set up on the construction site, which are divided into mobile unloading platforms, floor-standing unloading platforms, and cantilevered unloading platforms. In the existing technology, in order to improve the safety of the construction platform, guardrails or baffles are set at the outer edge of the construction platform to provide anti-fall protection for the construction platform and prevent people from falling from the construction platform. However, the construction personnel on the construction site are complex, and some construction personnel have low safety awareness. During the construction process, personnel will get too close to the outer edge of the construction platform, which increases the probability of people falling from the construction platform.
