Abstract

The invention discloses a remote monitoring system and method of suspension bridge cable state. The monitoring system comprises a sensor detection unit, wherein the sensor detection unit consists of a plurality of sensor detection subunits; each sensor detection subunit consists of a sensor, a microcontroller I and a radio frequency tag, detects a parameter of cable safety state, and transmits the parameter to a radio frequency read / write unit in a radio frequency manner; the radio frequency read / write unit consists of a plurality of radio frequency read / write subunits; each radio frequency read / write subunit consists of a radio frequency read / write device and a microcontroller II, reads data information of the radio frequency tag and transfers the data information to a wireless transmitting unit; the wireless transmitting unit comprises a wireless transmitter and a microcontroller III, receives the data information transferred by the radio frequency read / write device and transmits the data information to a remote control terminal; the remote control terminal receives and analyzes the data information transmitted by the wireless transmitter of the wireless transmitting unit and performs comprehensive assessment on the safety state of each position of the cable. According to the invention, the system can remotely monitor the safety state of the cable of a suspension bridge and is high in precision and low in 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...
