With the rapid development of the Industrial Internet of Things, data acquisition and processing technology has become a research hotspot. This paper focuses on the industrial Internet data acquisition and processing technology. In view of the current situation and existing problems of industrial Internet data collection technology, such as slow transmission speed, low data quality, poor security, etc., from the three aspects of data transmission, data processing and data security. Specifically, the transmission mode based on the Internet of Things, distributed data processing technology and encryption algorithm and other technical means are adopted to improve the speed and quality of data transmission and ensure the data security. The research results of this paper provide reference and reference for the further development of industrial Internet data acquisition and processing technology, which has certain theoretical and practical significance.

MES system is an integrated information system integrating multiple functional modules, which is used to manage and monitor the production process and improve the production efficiency and quality. With the rapid development of the manufacturing industry, the manufacturing management system (MES) has become a key technology to improve the production efficiency and product quality of the manufacturing enterprises. In this paper, we deeply study and discuss the key technology and application of MES system. Through the design of the physical layer and software layer architecture of the MES system, including the overall system structure, database, functional module, system integration, etc., the development of the manufacturing management system (MES) is realized.

At present, most of the coating production still adopts relatively backward traditional methods, there are its equipment status, operation, production, repair and maintenance information of digital technology application less problems. In view of this problem, a data acquisition module and data processing system are developed to realize the data acquisition and real-time monitoring of the equipment temperature, vacuum degree, rotation speed, target material, film thickness and surface condition. The data acquisition module consists of a self-organized network system formed by the sensor nodes deployed in the detection area and installed on the device, combined with / wireless communication. Through the development of the system to achieve the digital and intelligent application of coating equipment.
