ZigBee and multi-hop routing-based ore pulp pipeline displacement fault detection system

Abstract

The invention relates to a ZigBee and multi-hop routing-based ore pulp pipeline displacement fault detection system.A plurality of acquisition nodes are arranged at each interface of an ore pulp pipeline; a coordination node is arranged in a central control room, and an ad hoc network is established by adopting a ZigBee wireless communication technology; all the acquisition nodes and the coordination node can communicate with each other, so that wireless transmission of data along the pipeline and real-time monitoring of the displacement of the pipeline are realized; the system adopts an AVDOjr multi-hop routing algorithm, realizes cascade long-distance data transmission and network self-healing functions, and can work normally under the condition that a certain node fails; displacement information acquired by the acquisition nodes is transmitted to the coordination node through the wireless ad hoc network and then is transmitted to the PC by the coordination node through an RS232 bus, and the PC displays and stores data. According to the invention, the displacement fault condition of the ore pulp pipeline can be monitored on line in real time, and early warning is carried out, so that stable conveying operation of the ore pulp pipeline is effectively guaranteed, and economic losses and environmental pollution caused by displacement of a pipeline foundation are reduced.

Description

technical field [0001] The invention relates to an ore slurry pipeline displacement fault detection system based on ZigBee and multi-hop routing, which belongs to the technical field of measurement and control. Background technique [0002] The slurry pipeline is a special delivery pipeline that mixes granular solid minerals with liquid media, transports them by pumping, and separates them at the end of the pipeline. Compared with the traditional transportation methods (railway and road) in the past, pipeline transportation has the following characteristics: (1) less investment and faster construction speed; (2) not limited by terrain, short line distance and low transportation cost; (3) land occupation (4) It is not affected by climate change; (5) There is no no-load reverse transportation, which saves costs; (6) The equipment is reliable in operation and low in maintenance costs; (7) Generate noise and pollute the environment; (8) High degree of automation can save a lot ...
