Combined positioning cable machine operation monitoring system and cable machine anti-collision regulation and control method

Abstract

A combined positioning cable machine operation monitoring system and a cable machine anti-collision regulation and control method are disclosed. The system comprises a cable machine, a construction device, a first positioning device, a second positioning device, a combined positioning device, a first reference station, a second positioning base station, a wireless communication device, a synchronous controller, a positioning server, a database server and a display device. The invention also comprises a cable machine collision detection method, the cable machine anti-collision regulation and control method, a cable machine anti-collision shift up or shift down determining method and a data conversion and synthesis method for a combined positioning device. The system and the method disclosedin the invention are high in combined positioning precision and real time performance; a monitoring scope cannot be limited, a cable machine can be monitored in real time in a seamless manner, and cable machine construction processes can be monitored in a visualized manner; via the collision detection method and the anti-collision regulation and control method adopted in the invention, an effective cable machine anti-collision regulation and control mechanism is formed so as to ensure safe and highly efficient operation of the cable machine.

Description

technical field [0001] The invention belongs to the field of cable machine operation, and in particular relates to a combined positioning cable machine operation monitoring system and a cable machine anti-collision control method. Background technique [0002] The cable crane is easy to install, flexible, large lifting capacity, wide working range, high mechanical efficiency, and has the characteristics of being erected once and playing a role throughout the construction period. Therefore, it has been widely used in hydropower projects in my country, especially in the construction of high arch dams. used widely. However, most of the high arch dams in our country are built in the alpine and canyon areas, where the meteorological environment is harsh, the construction site is narrow, the construction activities are frequent, and there are many spatial cross operations, which may easily cause cable crane collision accidents. At present, in order to prevent the occurrence of cab...

AI Technical Summary

Problems solved by technology

[0003] There are following deficiencies in the above-mentioned cable crane positioning and anti-collision methods: first, for areas such as high mountains and valleys where arch dams are constructed, other global positioning such as GPS or Beidou is adopted, and its satellite signals are seriously blocked, especially in the valley foundation pit position (also known as cable crane location). When the hanging tank is transported into the warehouse), the number of visible satellites decreases sharply. When there are less than 4 satellites, the positioning accuracy of GPS, especially the vertical accuracy, will be significantly reduced.
