Video monitoring and walkie-talkie network system used for high-rise building construction

Abstract

The invention relates to a video monitoring and wireless walkie-talkie network system used for a high-rise building construction. The system comprises a video monitoring subsystem and a wireless walkie-talkie subsystem. The video monitoring subsystem comprises a front-end image and video capture portion, a middle image signal and video signal transmission portion and a central image switching, controlling and storing portion; the front-end image and video capture portion includes video cameras; the middle image signal and video signal transmission portion includes horizontal copper cables, an optical transceiver and a backbone optical fiber; the central image switching, controlling and storing portion comprises a coder, a hard disk recorder and a monitor which are both arranged inside a master-control room. The wireless walkie-talkie subsystem comprises an indoor antenna which is used for receiving walkie-talkie signals. The video monitoring and walkie-talkie network system used for the high-rise building construction enables the functions of the video monitoring system to be more complete, and achieves the full coverage of the walkie-talkie system signals.

Description

technical field [0001] The invention relates to the technical field of signal processing for high-rise building construction, in particular to a video monitoring and wireless intercom signal coverage system for high-rise building construction. Background technique [0002] With the continuous progress of society, the concept of safe production has been deeply rooted in the hearts of the people, and people's requirements for safe production are getting higher and higher. The construction industry is an industry with frequent safety accidents, especially how to ensure the personal safety of construction personnel when hoisting equipment and materials, as well as the safety of building materials, equipment and other properties on the construction site are the top concerns of construction units. [0003] The 35KV general step-down station of Shanghai Tower is located on the basement floor, and a total of 30 high-voltage cables are laid to the 8 substations above the ground, amon...

AI Technical Summary

Problems solved by technology

[0004] When hoisting cables in the electrical pipe shaft, personnel on different floors and key positions cannot visually see each other's operating conditions, and are completely blind to the progress of hoisting, the position of the cable head, the operation of the hoisting machinery, and the working status of the vertical steering pulley. Status, you can only know about the progress through the wireless walkie-talkie

However, this building is a super high-rise (skyscraper) building, and the vertical height of the tube well alone reaches 543 meters, and the signal of the wireless walkie-talkie in the tube well is shielded by the steel structure, and the signal strength, calling distance, voice clarity, etc. signal transmission work
