Tower crane data acquisition system based on Zig Bee is designed

aiming at requirement of running status monitoring

operation data obtaining

so as to ensure safe operation of the tower crane system. The system adopts modular design

through data acquisition module

Zig Bee networking module and the STM32 terminal module to realize intelligent monitoring of tower crane. Aiming at electromagnetic interference of Wi Fi on Zig Bee network

system adopts multichannel detection scheme

which preferrs to select the channel that has the smallest effect by Wi Fi channel distribution

which can make the Zig Bee node more efficiently find the available channel.Experiments show that the system has functions of fast networking

sensor real-time send data and interface display

it can also effectively reduce influence of interference. The research has important practical significance on safety monitoring and accident analysis of tower crane.
