Description

Technical Field

[0001] The present invention relates to the fields of 5G communication technology and crane operation monitoring technology, and in particular to a crane monitoring system and a monitoring method based on 5G communication. Background Art

[0002] Large cranes are important basic equipment in industrial production and engineering construction. Due to the complex operating conditions of cranes, they may malfunction or even cause accidents during operation due to abnormalities in some components. Therefore, it is necessary to regularly inspect and maintain cranes and monitor some important components during operation. In terms of structure, the load-bearing structure of the crane is prone to a series of deformation problems after working for a period of time. In terms of mechanism, damage and failure of components are prone to accidents of uncontrolled lifting. In terms of control systems, excessive temperature and electrical parameters are important causes of accidents. In the current large-scale application environment of crane equipment, more scientific and effective methods must be adopted to carry out inspection and testing of cranes to ensure the safe operation of cranes.

[0003] At present, the main problems in the inspection and testing of cranes include: the inspection and testing of cranes are mostly carried out on-site manually, which has many disadvantages, such as the huge workload of inspectors, the complicated data to be recorded, easy to make mistakes, and low efficiency; due to the limitations of working conditions, many important inspection projects cannot be carried out, or the inspection is not thorough, which lays hidden dangers for the subsequent work of the crane; the report is issued after the data is processed, which wastes time and cannot give the inspection results in time.

[0004] With the continuous development, improvement and widespread application of Internet of Things technology, sensors and detection devices for existing crane detection are emerging in an endless stream. Compared with traditional manual detection, they have extremely high detection efficiency and convenience, and can be detected during the operation of the crane and at idle time, which greatly improves flexibility and reliability. However, due to the complex working site conditions of the crane, the existing solutions using Internet of Things devices for detection still have some limitations or technical bottlenecks in data transmission, which makes the remote detection and monitoring of the crane have a certain lag or data transmission volatility, which is not conducive to the back-end management personnel to take timely management strategies.

[0005] With the continuous popularization of 5G network communication technology, its low latency characteristics enable data exchanged between devices to be transmitted efficiently and stably during long-distance wireless communication. Therefore, how to use 5G technology in the Internet of Things detection equipment of cranes to provide more reliable and timely data feedback for background remote management is a topic of very positive and practical significance. Summary of the invention
