Rigging tension on-line monitoring platform, monitoring system and method

Abstract

The invention belongs to the technical field of tension monitoring equipment, and discloses a rigging tension online monitoring platform, system and method. The platform comprises a data collection and transmission system, a data processing and control system, and a diagnosis and evaluation system. The data collection and transmission system, the data processing and control system and the diagnosis and evaluation system are connected in sequence; the data collection and transmission system consists of a rigging tension testing device, transmits monitoring data to the diagnosis system, compares the monitoring data with an input model, and transmits rigging information to the evaluation system; and the data processing and control system is composed of a data acquisition and transmission system, a data acquisition control module, a data classification and extraction module, a human-computer interaction interface and a data storage unit. Measurement of stress and strain on a sensitive metal sheet replaces direct measurement of the rigging, so that measurement data is more accurate; within a certain range, the size of the sensitive metal sheet and a rope belt is replaced, and the tension measuring range can be widened.

Description

technical field [0001] The invention belongs to the technical field of tension monitoring equipment, and in particular relates to an online monitoring platform, monitoring system and method for rigging tension. Background technique [0002] At present, the suspension cable structure is a load-bearing structure formed by flexible tension cables and their edge components. It is widely used in bridges, houses and other long-span buildings, such as gymnasiums, industrial workshops, cultural and living buildings, and special structures. Due to the great influence of the cables on the overall structural performance, periodic testing is required. Conventional detection methods not only affect the normal use of facilities, but also increase the cost of daily maintenance, so it is very important to study the online monitoring platform of rigging tension. [0003] There are mainly the following methods for safety inspection of rigging structure: 1. Tensile machine test method 2. Rigg...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing technology cannot solve the real-time monitoring of the rigging structure, and cannot make an early warning for the sudden damage of the rigging, and cannot make a judgment on the fatigue damage

[0006] (2) The detection of the existing technology is relatively cumbersome, which affects the normal use of the rigging structure during the detection period

[0007] (3) The existing technology needs to be tested periodically, and the cost of use is relatively high
