Problems solved by technology
The realization of intelligent manufacturing requires the joint participation of users, controllers and field devices. The three-layer architecture of user layer, control layer and device layer has been widely used in the field of manufacturing, but as the core layer of the three-layer It is mainly implemented through the integration of various controllers from different manufacturers, different protocols, and different interfaces. There are various problems such as protocol conversion, bus transmission delay, and compatibility. Data acquisition / device control requirements and industrial field controllers that can realize local / cloud data storage and access are particularly urgent

The invention discloses a method for designing a Hub controller oriented to manufacturing IoT. The method adopts the ZYNQ-7000 SoC design of Xilinx Company, including: designing a device perception module, which includes a protocol processing unit and a data preprocessing unit, Among them, the protocol processing unit is responsible for data collection of heterogeneous equipment and issuing control instructions, and the data preprocessing unit is responsible for generating data frames that meet user needs; designing a comprehensive processing module, which includes a server unit, a data transmission unit and a digital Twin unit, in which the server unit is responsible for building an embedded server, the data transmission unit is responsible for data transmission with the device perception module and concurrent communication with the external LAN and WAN, and the digital twin unit is responsible for storing and controlling the virtual model of the device to realize the physical entity of the device Linkage with virtual model.
Description
technical field [0001] The invention belongs to the fields of electronic engineering and computer science, and in particular relates to a design method for a Hub controller oriented to manufacturing IoT. Background technique [0002] Intelligent manufacturing has become a key development field in my country and even in the world. Intelligent units, intelligent workshops, and intelligent factories are the primary prerequisites for realizing intelligent manufacturing. factory premises. The realization of intelligent manufacturing requires the joint participation of users, controllers and field devices. The three-layer architecture of user layer, control layer and device layer has been widely used in the field of manufacturing, but as the core layer of the three-layer It is mainly implemented through the integration of various controllers from different manufacturers, different protocols, and different interfaces. There are various problems such as protocol conversion, bus tran...
