Universal PCB manufacturing equipment information acquisition system based on OPC UA

Abstract

The invention provides a universal PCB manufacturing equipment information acquisition system based on OPC UA; a PCB equipment operation model is provided through abstracting the operation process ofPCB equipment, and an equipment state switching model is described according to the model; through PCB industry data abstraction, a unified industry equipment acquisition information coding table is constructed. According to the PCB equipment operation model, the state switching model and the equipment acquisition information coding table, an OPC UA application is combined, and a PCB equipment information acquisition data model TMSmodem is provided. A client data acquisition system TMSclient is deployed in a field device or a field controller, and is mainly responsible for acquiring, analyzingand uploading equipment information and product information, and receiving a control command issued by a server. The server-side data receiving and storing system TMSserver is deployed in a factory machine room server, and is mainly responsible for receiving, analyzing and storing information transmitted by a factory equipment side, performing data mining on original information stored in a database according to different service requirements, and outputting an intelligent display board and an intelligent report.

Description

technical field [0001] The invention designs the field of industrial automation, and in particular relates to a general-purpose PCB equipment data acquisition system based on the OPC UA protocol used in the PCB discrete manufacturing industry in the field of industrial automation. Background technique [0002] In the traditional printed circuit board PCB industry, due to the complex manufacturing process and large quantity, it is difficult to control the delivery time and quality, and the production process is difficult to trace and other problems are becoming increasingly prominent. Driven by the Industrial Internet, in order to solve the above problems, it is necessary to network all kinds of production equipment and collect production information of various equipment in real time to build a digital smart factory. [0003] On the other hand, in the PCB manufacturing industry, the process flow is complex, there are more than 20 procedures, and there are various types of equ...

Problems solved by technology

[0003] On the other hand, in the PCB manufacturing industry, the process flow is complex, there are more than 20 procedures, and there are various types of equipment. In order to realize the information collection of the underlying equipment, it is necessary to target each type of field equipment, or even the same type of equipment from different manufacturers. Customized development of data acquisition programs not only requires a large workload, but also the data format is not uniform, making it impossible to connect devices
