Intelligent control system for tower crane

Abstract

The invention discloses an intelligent control system for a tower crane, and belongs to the field of construction engineering machinery. The control system comprises a control center, a wireless communication module, a cloud server, a mobile control terminal, a high-definition video monitoring module, a lifting hook intelligent obstacle avoidance module, a data acquisition and transmission module, an action execution module and an alarm module, the cloud server, the mobile control terminal, the high-definition video monitoring module and the lifting hook intelligent obstacle avoidance module are connected with the control center through the wireless communication module, and the data acquisition and transmission module, the action execution module and the alarm module are connected with the control center. According to the intelligent control system for the tower crane, the core components of the tower crane are integrated through information technology means and are not detachable, so that intelligent operation and intelligent obstacle avoidance within the calibration range of the tower crane are realized, the labor cost of tower crane operation is reduced, the potential safety hazard of construction is further reduced, and the hoisting operation efficiency of the tower crane is improved.

Description

technical field [0001] The invention relates to the technical field of building construction machinery, in particular to an intelligent control system for tower cranes. Background technique [0002] Tower cranes (tower cranes) undertake the main work of vertically and horizontally transporting heavy objects in construction and bridge construction scenarios, and are indispensable and important construction machinery in the process of urban modernization. During the operation of traditional tower cranes, at least one tower crane driver, two signal workers, and one cable operator are usually equipped. Not only the labor cost is high, but also there are many unsafe behaviors of people, such as lack of safety awareness and negligence, unintended Work with certificates, illegal operations, skill differences, etc., accounted for more than 60% of tower crane safety accidents. Therefore, it is of positive significance to study the intelligent control system of tower cranes to realiz...

Problems solved by technology

[0003] From the point of view of the tower crane control system, the main problems of the existing domestic tower crane control system are: (1) The control mode of some old tower cranes still adopts the relay form, which is simple and rude, and has a large impact on the motor and equipment; The control system and the monitoring system are independent, without information interaction; (3) the tower crane can only realize simple fixed-point and fixed-distance operation, the reliability is not high, and there is still a long way from unmanned driving; (4) the main components of the tower crane ( For example, motors, reducers, hydraulic jacking systems, etc.) are not closely related to the main control center, and are easily disassembled and replaced with those that do not match the original parameters, resulting in poor performance and unstable operation of the tower crane, which is not conducive to the intelligent control of the tower crane system integration
