Abstract

Intelligent manufacturing has become a research hotspot, as the development direction of the new generation manufacturing system. CNC machine tools are the core manufacturing equipment of discrete manufacturing enterprises, however the traditional remote monitoring method for five-axis CNC machine tools has some problems, such as access latency, short coverage distance, low utilization rate of equipment, and so on. To solve this problem, this study proposed a remote intelligent monitoring system based on MQTT and LoRa communication for five-axis CNC machine tool. And the system integrates multi-source sensor signals of CNC machine tools to conduct synchronous real-time monitoring, interface control and fault alarm for multiple five-axis CNC machine tools. The results show that the system can monitor the functions and production process status of five-axis CNC machine tools within 3km based on MQTT and LoRa communication, and remotely realize the linkage control and real-time monitoring of multiple NC machining equipment by publishing and subscribing the status information of machine tools in real time.
基于MQTT和LoRa通信的五轴数控机床远程智能监控系统研究
智能制造作为新一代制造系统的发展方向,已成为研究热点。数控机床是离散制造企业的核心制造设备,但传统的五轴数控机床远程监控方法存在接入延迟、覆盖距离短、设备利用率低等问题。针对这一问题,本研究提出了一种基于MQTT和LoRa通信的五轴数控机床远程智能监控系统。该系统集成数控机床多源传感器信号,对多台五轴数控机床进行同步实时监控、接口控制和故障报警。结果表明,该系统基于MQTT和LoRa通信,可以实时监控3km范围内五轴数控机床的功能和生产过程状态,并通过机床状态信息的实时发布和订阅,远程实现多台数控加工设备的联动控制和实时监控。
