LoRa based quayside data wireless monitoring system

Abstract

The invention discloses a LoRa based quayside data wireless monitoring system which comprises a terminal sensing system, a sensor gateway, a network server and a central monitoring platform. In recentyears, the logistics industry develops rapidly, establishment of ancillary facilities is gradually comprehensive, and the requirements for large structure equipment of harbors and wharfs are continuously enhanced. A set of perfect monitoring system is self-evident to the safety of the whole harbor. Aiming to the specificity of a harbor working field, the invention provides the LoRa based quaysidedata wireless monitoring system to perform data collection on a quayside container crane. The system takes LoRa radio frequency module as a core and adopts a star-shaped networking manner to realizedata interaction. The general situations including a network architecture mechanism and a working mode are elaborated in details, and the existing data transmission method is improved by combining with the characteristics of a harbor mechanical structure. LoRa, as a newly-developing communication network, is applied to the field of sea harbors, fully exerts the advantages of long transmission distance, low power consumption and the like, realizes quayside work real-time monitoring, data transmission, intelligent management and control and guarantees reliable and stable running of large equipment.

Description

technical field [0001] The invention relates to the field of low power consumption wide area network communication, in particular to a LoRa-based wireless monitoring system for quay crane data. Background technique [0002] With the rapid development of the logistics industry, the requirements for port lifting equipment have also increased accordingly. The port crane is a kind of heavy machinery equipment with very heavy working conditions, its load is complex and changeable, and its dynamic characteristics are remarkable. As the most important loading and unloading equipment in container ports, the normal operation of quay cranes directly affects the production efficiency and economy of the port. It is the general trend to improve the management level of port equipment by installing sensors in key parts of the quay crane to monitor the quay crane. At present, the existing sensors are connected to the host through cables. This traditional wired communication method is lack...
