The invention provides a foundation pit excavation state
monitoring system and method based on
laser range finder networking, and belongs to the field of earth excavation. A detection unit comprises multiple
laser range finders; the multiple
laser range finders are uniformly erected on the side face of a crown beam of an excavated foundation pit or the lower part of a support beam; a first
wireless transmission module is packaged in each laser range finder; each laser range finder is use for acquiring earth excavation basic information at a certain time in a certain section, feeding back the earth excavation basic information to a monitoring unit through the first
wireless transmission modules, and meanwhile, receiving a
remote control command of the monitoring unit through the first
wireless transmission modules so as to execute active /
passive control commands; and the monitoring unit comprises a second
wireless transmission module, a
data processing and analyzing module, a networkingcontrol module, a
monitoring data display module, a
monitoring data storage module and a monitoring and early earning module. According to the foundation pit excavation state
monitoring system and method based on laser range finder networking provided by the invention, the speed of acquiring the earth excavation state is fast, the
data processing difficulty is low, and the application cost is low.
