Data Acquisition and Organization of Remote Monitoring System for Gantry Cranes

Reasonable data acquisition method and excellent data organization and management structure are fundamental guarantees for the reliable operation of the remote gantry crane monitoring system. In this paper, the architecture of gantry crane remote monitoring data flow is established, and acquisition of sorted data is analyzed. The data management structure of the remote crane monitoring system for large amount of data with multi users and multi equipments is established by using the E-R model, thus the robustness and maintainability of monitoring system are improved. Real-time database and CMS gateway are designed to ensure the data continuity during the disconnection-recovery of field wireless network. This study provides a basis for further fault diagnosis, performance prediction and none downtime intelligent maintenance of gantry cranes.
