Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] figure 1 It is the overall structure diagram of the monitoring and fault diagnosis system in this embodiment, describing the information connection between the system and the crane.

[0033] The system consists of five parts: signal pickup subsystem 1, data acquisition subsystem 2, field monitoring and alarm subsystem 3, wireless communication subsystem 4, and remote monitoring and diagnosis subsystem 5. Signal pickup subsystem 1 acquires status signals from different parts of the crane; outputs them to data acquisition subsystem 2 for preprocessing such as filtering and amplification and data acquisition; the collected data is transmitted and stored to on-site monitoring and alarm subsystem 3 for status display and fault alarm; then the real-time data stored on site is transmitted to the remote monitoring and diagnosis subsystem 5 thro...

Abstract

The invention discloses an online and fault diagnosing system for a crane. The system comprises: a signal collection subsystem which is used for obtaining various state information in the crane operation process; a datum acquisition subsystem which is used for acquiring the information obtained by the signal collection subsystem, preprocessing the information and outputting the information; an online monitoring and alarming subsystem which is used for analyzing the information output by the datum acquisition subsystem, the online monitoring, and the fault alarming; a wireless communication subsystem which is used for positioning the crane and transmitting data input to the online monitoring and alarming subsystem; and a remote monitoring and diagnosing subsystem which is used receiving and analyzing the data transmitted by the wireless communication subsystem to realize online monitoring, fault alarming, fault diagnosing and trend analyzing in a remote manner. The system has the functions of online monitoring, advance warning and alarming, analyzing, diagnosing, wireless communication remote monitoring and the like, so reliable bases are provided for the safe operation of the crane, and safety accidents are avoided or reduced.

Description

technical field [0001] The invention relates to the field of monitoring and maintenance of cranes, in particular to an online monitoring and fault diagnosis system for cranes, especially suitable for bridge cranes, gantry cranes and tower cranes. Background technique [0002] Crane is a kind of large-scale engineering machinery used for lifting and transporting heavy objects. It is often used in industries such as construction, bridges, metallurgy, ports, electric power, petrochemicals, and automobiles. According to the structural shape, it can be divided into: bridge crane, gantry crane and tower crane. [0003] Some cranes work in the open air outdoors, experience wind, frost, snow, rain, and even overload operation. After a long period of operation, various failures will inevitably occur. The occurrence of failure not only affects the normal operation of the crane, but also may lead to safety accidents, and even cause major economic losses or casualties. It is not uncom...
