Abstract

A D-GPS and RFID fused early warning method against a risk caused by a suspended cage of a cable crane comprises the following steps that an early-warning device determines an area where a construction staff is positioned, and when the construction staff is in an unsafe area, voice caution is provided; real-time spatial position coordinates (X1, Y1, Z1) and the operation speed v of the suspended cage of the cable crane and the spatial position coordinates (X2, Y2, Z2) of the construction staff are measured, the horizontal displacement between the suspended cage of the cable crane and the construction staff is compared with an object striking influence area of the suspended cage of the cable crane, and early warning is provided for the construction staff in a distance early-warning way; andwhen the construction staff enters the object striking influence area of the suspended cage of the cable crane, buzzing caution is carried out till the construction evacuates to a safe area. The object striking influence area of the suspended cage of the cable crane is calculated via positioning technologies, the risk caused by spatial conflict is reduced effectively, and the safety of the construction staff in the construction process is improved.

Description

technical field

[0001] The invention relates to a method for early warning of disaster risk caused by hoisting a tank by a cable crane that integrates D-GPS and RFID, and relates to the technical field of dam construction pouring and hoisting. Background technique

[0002] In the high dam projects that have been built at home and abroad, concrete pouring is indispensable. Among them, the cable crane is widely used in the pouring and hoisting of dam construction, and plays an important role in the entire dam construction period due to its advantages of high lifting height, large operating range, long working hours, and high hoisting efficiency. However, during the dam construction process, when the cable crane and different types of work are simultaneously constructed in the limited dam surface space, due to the limitation of the construction schedule and construction technology, a large number of three-dimensional intersection operations are likely to occur. The three-dimen...
