Automatic control system for a cable strand traction system of a suspension bridge, and monitoring platform

Abstract

The invention discloses an automatic control system for a cable strand traction system of a suspension bridge, which comprises a traction system, a data processing center and a winch chamber control module. The traction system comprises a main traction winch, an auxiliary traction winch, a first traction rope, a second traction rope, a third traction rope, a first puller, a second puller, an anchor gantry guide wheel set, a catwalk gantry guide wheel set, a tower top gantry guide wheel set, an anchor back gantry guide wheel set, a rotary wheel, an RFID electronic tag, an RFID card reader and afirst wireless communication terminal. The RFID card reader can send the encoded information of the read RFID electronic tag to the data processing center through the first wireless communication terminal, and the data processing center analyzes the encoded information and sends corresponding control instructions to the control module of the hoist room to control the hoist or the hoist to performcorresponding operation. The control system can realize the automatic monitoring of the puller and the automatic control of the puller without human manipulation and save the human cost.

Description

technical field [0001] The invention relates to the technical field of main cable erection of a suspension bridge, in particular to an automatic control system for a suspension bridge strand traction system and a monitoring platform for a suspension bridge strand traction system based on the Internet of Things. Background technique [0002] With the development of science and technology and national economy, my country has increased the investment and construction of transportation infrastructure, and many super-long-span bridges have been built and opened to traffic one after another. Among them, suspension bridges are one of the main forms of super-long-span bridges. The central part of the installation and construction of the upper structure of the suspension bridge on the traction system, in addition to being used for the erection of the main cable strand, it also undertakes the erection of the catwalk in the early stage. The design of the traction system will directly af...

Problems solved by technology

In the existing traction system, it is impossible to automatically monitor the position of the puller in the traction system. Usually, the position is judged manually and radio communication is used on site to notify other staff to perform corresponding operations.

Manual judgment of the position is prone to deviation, and the staff cannot always pay attention to the dynamics of the puller, which is prone to mistakes; in addition, the labor cost is high by manually controlling the puller
