Modular and bus real-time monitoring system for tower crane

Abstract

A real-time monitoring system of a modularized and bus-type tower crane belongs to the technical field of mechanical and electrical integration and comprises a bus-type field information acquisition terminal, a bus-type data processing module, a bus-type functional expansion unit, wherein, the bus-type field information acquisition terminal completes the concentration of the analog quantity information and pulse quantity information of the field status, and sends the status information and a mark to the bus-type data processing module by a CAN bus; the bus-type data processing module sends parameter classification information to the bus functional expansion unit; in the bus-type functional expansion unit, a bus-type field display unit performs the working status display and alarm of the tower crane according to the CAN bus information received; a bus-type remote communication unit sends the status information to a remote monitoring center; and a bus-type field control unit controls electric motors of the tower crane according to the CAN bus information received. The real-time monitoring system meets the requirements of flexible expansion of the monitoring parameters and compatibility and exchangeability of product.

Description

technical field [0001] The invention relates to a monitoring system in the technical field of electromechanical integration, in particular to a modularized and bus-based real-time monitoring system for tower cranes. Background technique [0002] Tower cranes are the most commonly used construction machinery in the construction field, and they are also one of the most accident-prone construction machinery. With the development of tower cranes in the direction of large-scale and automation, its status monitoring and real-time monitoring are becoming more and more important. At present, there is a lack of unified standards for tower crane monitoring systems on the market, and it is useless to widely promote and apply real-time monitoring systems. The development of a standardized and easy-to-promote real-time monitoring system for tower cranes has become an important means to ensure the safety of tower crane operations. [0003] After searching the literature of the existing t...
