Intelligent device system capable of preventing building jumping and intercepting objects falling from high altitude

The invention provides an intelligent device system capable of preventing building jumping and intercepting objects falling from the high altitude. An elastic net intercepting unit is composed of multiple elastic net type interceptors. Each elastic net type interceptor comprises a box type shell and two ejection mechanisms. Each box type shell is provided with an intercepting net storing groove and two ejector cavities, wherein the two ejection mechanisms are installed in the two ejector cavities correspondingly. Springs are fixedly connected to a spring base and are in elastic fitting with traction springs. First connecting portions and second connecting portions are arranged on the spring base and the traction springs in a corresponding manner. Connecting needles penetrating through thefirst connecting portions and the second connecting portions are fixedly connected to the end portion of a moving iron core of a push-pull electromagnet. A net bag is arranged in each intercepting netstoring groove. The inner
