Problems solved by technology

However, the safety monitoring methods of crane monitors at this stage often ignore the calculation and recording of the specific parameters SWP and BRSWP of the crane
Moreover, the current crane monitors often cannot support multi-machine collaborative monitoring, so that when multi-machines work together, it appears to be inefficient

Abstract

The invention discloses a safety monitoring method for a crane monitor, and belongs to the field of safety monitoring of cranes. The method comprises the following steps of: acquiring three-phase electric voltage signals, and detecting whether a phase defaults; detecting whether a three-phase electric voltage phase sequence is accurate; detecting whether a crane has an action request; detecting whether the crane is in a double-machine coordination state; and processing the action request of the crane and calculating the operating parameters of the crane. By the safety monitoring method for the crane monitor, the use safety accidents of the crane are reduced, the operating safety of the crane is improved, monitoring of multiple operating data of the crane is provided, the requirement of a user for control of the crane can be met, a double-machine coordination function is provided at the same time, integral safety monitoring when multiple machines work simultaneously becomes possible, and the crane runs more safely, more stably and more effectively.

Description

technical field [0001] The invention relates to a safety monitoring method of a crane monitor, in more detail, relates to a method for analyzing the running state of a crane based on a large amount of crane running data and giving running suggestions, which belongs to the field of crane safety monitoring. Background technique [0002] Usually the safety monitoring method of the crane monitor is mainly to judge whether the crane is overloaded and to record some operating data of the crane. This monitoring method is simple to operate and easy to maintain, but its function is relatively single. Since the crane is a special equipment, the aging and wear of the equipment have a great impact on the safety of the operation. The aging and wear of its main components can generally be reflected by specific parameters such as SWP, BRSWP and other data. Monitoring the above parameters can be indirectly Knowing the current crane operating status, remaining use time (number of operations...
