Abstract

The invention discloses a method for dynamically sensing regional personnel positioning of a portal crane based on millimeter-wave radars. The method comprises the following specific steps: arranging a plurality of millimeter-wave radars which are arranged in the transverse direction and the longitudinal direction on a cart which linearly walks on the portal crane; a radar 4D graph under operation of the portal crane is formed through micro-Doppler features, distances, angles and the like of a plurality of millimeter-wave radars, personnel feature information in the radar 4D graph is analyzed and judged, and if it is obtained through analysis of the plurality of millimeter-wave radars that an operator is located at a high-risk position, the system gives a prompt and an alarm. According to the invention, the plurality of millimeter wave radar heads are used for positioning and monitoring the operators below the portal crane, the positioning is simple, the cost is low, the realization is fast, and the positioning information acquisition of the operators of the portal crane is realized, so that the systematic automatic management is convenient, and the safety management effect of the operation area of the portal crane is improved. The patent comes from the science and technology research subject of the railway container intelligent station key technology research of the Chinese railway group limited company, and the subject number is N2020X009.

Description

technical field [0001] The invention belongs to the technical field of safety identification of railway container cranes, and in particular relates to a method for dynamically sensing personnel positioning in a gantry crane area based on millimeter-wave radar. Background technique [0002] In the existing railway container yard operations, gantry cranes have been widely used for hoisting operations. Most of the gantry cranes on site are only installed with gantry crane monitoring, and no real-time intelligent analysis has been achieved. They can only be used for future reference. The safety situation of on-site operations is severe, and various safety accidents occur from time to time. At present, there is no way to intelligently analyze and judge whether the operators are installed or not, especially for the workers working under the gantry crane. The risk of operation safety is high, and there is an urgent need for real-time and effective monitoring of compliance operation...
