Abstract

A remote monitoring system and monitoring method for the cable state of a suspension bridge. The monitoring system includes a sensor detection unit. The sensor detection unit is composed of a plurality of sensor detection subunits. The safety state parameters of the cable are transmitted to the radio frequency reading and writing unit in the form of radio frequency; the radio frequency reading and writing unit is composed of a plurality of radio frequency reading and writing subunits, and each radio frequency reading and writing subunit is composed of a radio frequency reading and writing device and a microcontroller. Read the data information of the radio frequency tag and transmit it to the wireless sending unit; the wireless sending unit includes a wireless transmitter and a microcontroller three, receive the data information transmitted by the radio frequency reader and send it to the remote control terminal wirelessly; remotely receive and analyze all The data information sent by the wireless transmitter of the wireless sending unit is used to comprehensively evaluate the safety status of each position of the cable. The system can remotely monitor the cable safety status of the suspension bridge with high precision and low cost.

Description

technical field [0001] The invention relates to a comprehensive monitoring system and a monitoring method for cable safety of a suspension bridge, belonging to the field of civil engineering. Background technique [0002] The suspension bridge is a flexible suspension system composed of main cables, stiffening beams, main towers, saddles, anchorages, slings and other components. The main cable is the most important load-bearing member in the structural system of the suspension bridge. It is suspended on the main tower through the tower top cable saddle and anchored in the anchors at both ends. The sling is a force-transmitting member that transmits the self-weight and external load of the stiffening beam to the main cable, and is the link connecting the stiffening beam and the main cable. Both are very important components in the structural system of the suspension bridge. However, the main cables and slings will be corroded during use, which will affect their strength; an...
