Description

Technical Field

[0001] The utility model specifically relates to an embedded industrial gateway for machine tool electric disk Internet of Things. Background Art

[0002] With the rise of machine tool IoT, a large number of CNC machine tool manufacturers and CNC machine tool end customers hope to achieve data collection and more intelligent functions (such as equipment monitoring, remote start and stop, equipment domain maintenance, etc.) through machine tool IoT. These intelligent functions rely on the collection of various data in the machine tool.

[0003] At present, the data collection of machine tools generally adopts adding an industrial gateway to the machine tool cabinet to realize the data collection of CNC or PLC, thereby realizing the collection of a large amount of machine tool operation data. This kind of industrial gateway is external, like a component module track-type or directly drilled screws installed on the track or sheet metal shell of the machine tool cabinet. They occupy part of the space of the machine tool cabinet, connect to the CNC system of the machine tool through the network cable, and use the protocol conversion in the industrial gateway to realize communication with the CNC system of the machine tool and obtain the machine tool data in the CNC system.

[0004] The above method can obtain most of the machine tool data, but the machine tool operation data generated by the machine tool panel in the machine tool electrical cabinet cannot be obtained through the industrial gateway, such as the status, operating current, voltage, etc. of the electrical components of the machine tool panel.

[0005] Furthermore, currently, CNC machine tool manufacturers generally use electrical components or modules to integrate the electrical cabinets into machine tool panels according to the electrical schematic diagram. This type of machine tool panel has too many electrical components or modules, which results in a huge wiring workload, greatly reducing the production efficiency of CNC machine tool manufacturers.

[0006] Subsequently, a new type of integrated PCB machine tool panel came into being, replacing the traditional machine tool panel. The integrated PCB machine tool panel realizes the functions of the original machine tool panel through electronic circuits. The new machine tool panel is essentially an integrated PCB, with only external input and output interfaces and power ports, which fully realizes the functions of the traditional machine tool panel and greatly reduces the workload of electrical wiring. This new type of machine tool panel will also generate a large amount of machine tool operation data during its operation. The collection of this data can help realize more intelligent functions such as machine tool status monitoring, fault analysis, and diagnosis. However, it does not have the ability of machine tool IoT, and it is difficult to realize machine tool IoT quickly and conveniently. Utility Model Content
