Construction hoist security application for tall building construction in wireless networks

With the radio frequency transceiver CC1101, a construction elevator security application for tall building construction is presented. The construction elevator security system consists of a paging system and a self-locking strategy for landing door. A variant binary exponential back-off (variant BEB) messaging model is proposed to lower the package collision probability in multi-channel paging process. With the variant BEB model, transmitters may effectively ensure fairness in wireless shared channel. Self-locking mechanism of landing door based on wireless signal networks is presented with the combination of electrical and mechanical locking. Experimental results show the validity of proposed construction hoist security application in the wireless signal network.
