Tower crane anti-collision on-line monitoring and early warning system based on ultrasonic sensing network and method thereof

Abstract

The invention discloses a tower crane anti-collision early warning system based on an ultrasonic sensing network and a method thereof. A multi-ultrasonic sensor fusion technology is adopted for monitoring surrounding obstacles of the tower crane, collision early warning information of the tower crane is acquired by positioning and identification of the obstacles, prediction of tracks and calculation of existing ultrasonic map data anti-collision model, and possible collision state is notified to the driver of the tower crane in time. The system comprises a main controller module and an ultrasonic monitoring point module which communicate with each other in a wireless network form, and the ultrasonic monitoring point module adopts an ultrasonic sensor for monitoring the surrounding obstacles of the tower crane. The system and the method solve the difficult problem of tower crane active anti-collision monitoring, and are characterized by strong anti-jamming capability, good real-time and easy-to-use, thus effectively reducing the labor intensity of the driver of the tower crane, improving the anti-collision monitoring level of the tower crane, reducing the occurrence of tower crane collision accidents, and leading the tower crane to run safely and efficiently.

Description

technical field [0001] The invention relates to a tower crane safety monitoring system, in particular to a tower crane anti-collision online monitoring and early warning system based on an ultrasonic sensor network and an online monitoring and early warning method using the system. Background technique [0002] Tower crane (hereinafter referred to as tower crane) is the crane with the largest working space in the construction industry. It has a high lifting height and a large working range. With the sustained and rapid development of my country's economy, the scale of the construction industry has continued to expand, and tower cranes have created good economic and social benefits. [0003] With the expansion of urban capital construction scale, urban building density continues to increase. The operation of tower cranes on new construction sites will be affected by surrounding existing buildings or other obstacles, and there are many hidden dangers of collisions during oper...
